Bought my car here 3 years ago. I have never had an excellent experience with the service department. Only one time have I been greeted outside when I pulled into the service bay. I have to go in to the service department and every person seems engrossed on their phone call or their computer and gives off the vibe of "please don't choose me!" Yesterday is the first time I was greeted with a smile and offer to help. I must insert here that I have visited Lexus Plano many times with my friend. There is ALWAYS a person to greet her, outside, BY NAME. So I know what excellent service looks like. I called for status of my car; spoke to three humans who put me back on hold until I get the business's generic voicemail to leave a message. It has been 24 hours since I left my car AT an appointment time, which I made online because I could not get anyone to answer the phone in the service department to let me explain my issues before I made an appointment! with an appointment, I feel a mechanic should have had that time set aside to examine my car or perform the service for which I left it. read more

I bought a used 2025 Corvette Z06 on March 7, 2026. The sale price was decent at $101,888.00. I traveled 4.5 hours from Tulsa to buy the car and had been pre-approved for financing. I wired the dealer $10k days before. I told my sales guy I needed to be home by 4:30 because I am in a band and was playing that evening. 1- I was stuck arguing about extended warranties and maintenance plans that I would never use and the car was under full factory bumper to bumper warranty. I usually only keep my cars for a year or maybe 2 tops. Over an hour debating with Gibert Martinez, the finance guy would not do a bare bones contract. I did plan on refinancing when I got home to get a 3.49% APR at my credit union. So, finally at around 12:30 said fine, I'll just cancel the warranty and maintenance when I get home. I HAD TO GO to be home in time. (I had to speed the whole way home and was still 1 hour late because we ran into 2 plus hours of bad weather.) 2- When I received my contract there was an additional paint and interior warranty for $1349.00 which btw was never applied. Sunday, I rinsed the car off and the water did not bead up at all. NO paint protection wax or silicone or ceramic coating was applied to my car. I took the car that week to a reputable detail shop and they did checks on the car. It showed no wax or any paint protection on the car was ever applied. ZAKTEK is a interior and exterior protection "warranty" that in non- refundable and also never applied. 3- The contract numbers do NOT add up. OKlahoma sales tax $4647.78, Ext. Warranty $2150.41 (although contract states $2205) Maintenance agreement $960.00, Doc fee $225, Government license fee $800 (?), Etag $10, dealer inventory tax $155.41, price of car (listed at $101,888) add all up equals $110,836.60, plus $10,000 down should be $100,836.60 financed. But the contract says $103,535.17 financed. That's a $2698.57 discrepancy. Remember point 2? the $1349 for the non applied ZAKTEK? guess what $1349 x 2 comes to? $2698. Not only did they charge me for the paint protection that was never applied but they charged me twice. but the $1349 was not listed on the financed break down but I do have the contract in my paper work.... This is a deceptive, crooked company. DO NOT BUY FROM THEM!! you have been warned. LOOK AT THEIR YELP RATING 2.2 read more

Very disappointing experience at GMC McKinney. My vehicle sat there for an entire week, and I received poor communication and inaccurate information the whole time. My advisor, Tommy, repeatedly said he would follow up but never did, and I was given incorrect details about a recall and my warranty coverage, even though I have an active Platinum Elite plan. It was frustrating having to constantly seek updates myself, and to make matters worse, Tommy left without ensuring I was taken care of. I will say Brycen stepped in at the end and was extremely helpful and professional. He provided the level of service that should have been given from the start, and I truly appreciated his help. Overall, this experience lacked communication, accuracy, and accountability. I hope the dealership addresses these issues moving forward. read more

I own a 2024 GMC Sierra 2500 Duramax that I use for real towing and heavy work. During a routine oil change at McKinney Buick GMC, I received an inspection report through the Xtime system saying "1 item failed: Needs immediate attention." The "failed" item was a $220 EFI (Electronic Fuel Injection) system cleaning. Here is the problem. EFI cleaning is not a GM-required maintenance item. It is not part of the Duramax service schedule, it cannot "fail," and there is no way to diagnose the need for it during a basic oil change. The failure they flagged was simply not real. When I called the Service Manager to ask about it, he gave explanations that were technically impossible, including telling me you can "physically see carbon deposits coming out of the tailpipes" to justify the service. None of this is supported by GM documentation. I later spoke with the Fixed Operations Director. On a recorded call, he admitted that EFI cleaning is not GM-required, should not have been marked as a failed item, should not have been labeled "needs immediate attention," and should not have been recommended at 15,000 miles. He also acknowledged the way it was presented to me was incorrect. This was not an isolated incident. On a previous visit, they tried to sell me an oil "conditioner" that GM does not require or recommend. After seeing this pattern, I cannot trust them with major repairs on a $90,000 truck. If they are willing to misrepresent something this small, I do not want to find out how they handle bigger jobs. I have already moved all future service to another dealership and submitted a formal complaint to GM Corporate. If you bring your vehicle here, double-check any "failed" items against GM's maintenance schedule. My recorded call with the Service Manager is here: https://youtu.be/JKbQg1ME8l4 read more

We purchased a used 2020 Ford Expedition from McKinney Buick GMC and also paid separately for a 1-year powertrain warranty/service contract. We paid cash for the vehicle, signed paperwork, and were told the vehicle would go through the shop and be detailed before pickup. When we picked it up, it was barely cleaned, and shortly after purchase we began having concerns about the vehicle and warranty process. The biggest issue has been the complete lack of communication and professionalism from the dealership. Without our approval or agreement, the dealership apparently decided to cancel the warranty we legally purchased and is now mailing us a refund check instead of honoring the contract. At no point did we authorize cancellation of the warranty, and no one properly communicated this decision to us beforehand. We have repeatedly tried to get answers and clarity, but instead of transparency and customer service, we've been ignored and left to figure things out ourselves. Regardless of whether the vehicle was sold "as is," the separately purchased warranty was still a binding agreement that we paid for in good faith. The way this situation has been handled has been incredibly frustrating and disappointing. Customers deserve honest communication, accountability, and respect after making a major purchase. Unfortunately, that was not our experience with McKinney Buick GMC. read more

The manager there is an idiot who likes the salesman to scam customers. I was there in person at the dealership. Horrible sales tactics. Deceiving practices. Too many add ons. Overpriced vehicles. They hide and pocket manufacture incentives. No dealer incentives. Or they use the manufacture incentives as their own incentives. Just plainly stay away from this dealership. Save your money. Go somewhere else. Don't try negotiating with them online either. They will never give you an hones't offer. Allways overpriced unless you go to the dealership so they can waste your time. read more

--- Wow, thanks for the totally‑not‑copy‑and‑pasted response. Really refreshing to see the same exact script you leave under every negative review.Just so we're clear: I've had David Kellie's email since January -- but thank you for pretending like you just discovered fire by posting it again. He's been copied on multiple emails along with Rob and whoever else I could find, so the whole 'please reach out to us' routine is adorable.I also spent weeks trying to get your magician‑level‑disappearing service director, Jon, on the phone. Every time I called, I got the classic 'he'll call you right back' line. He finally materialized during the ice storm in mid January I believe.... then vanished again like a Snapchat message.So no, I don't need to 'reach out.' I already did -- repeatedly -- while juggling a job, a family, and the patience of a saint.Maybe instead of recycling the same generic reply you use on every unhappy customer, try actually responding like a real human being. -Clint read more

THIS is A SERVICE REVIEW. We have Been here a lot over the last few years. We have always dealt with Amanda in service. She is the best, always goes the extra mile to take care of us. Communicates every step of the way and explains everything in detail. She will give recommendations but never tries to sell up on things that don't need to be done. Honest! We will always take our vehicles here because of how we have been treated. Thank you Amanda! read more

I had the good fortune to have Adrianna as my service rep. She let me know right away she was new to the job and helped me to the extent of her experience and then involved others to successfully complete the mission that brought me to the dealership. She was good with follow-up, communicated the necessary information and tag team with their colleague Bryson to get the time sensitive information to me. She's the type of person that creates loyalty to a brand, to a company, to a dealership. I will definitely be coming back the next time I have a need. Thank you Adrianna. read more

The buying process with McKinney Buick GMC was completely deceptive; nothing they told us ended up being true. Kevin Currey, the pre-owned manager, and William Reigler, the sales consultant, both lied to us during the sales negotiations, and Kevin Escudero, the business manager, lied to us during the finance and warranty negotiations. We love the vehicle we bought, but I would never buy from McKinney Buick GMC ever again and will never recommend them to anybody else. Buyer Beware!!! read more

I purchased a 2026 GMC Hummer EV and specifically told Patrick Varrassi not to include the MPP service contract and he added it anyway. I stayed at the dealership from 3pm - 9pm dealing with lending and finance and I realized they spent that amount of time manipulating the contract. Be very careful of Patrick Varrassi in finance, when I called (5/30 @ 9:55am) and asked him why he added the MPP warranty even though I asked him not to do it he told me to call MPP and get it removed, no apologies and then he says it did not change my monthly payment but that's wasnt the point, it was the fact that I asked him not to add it. I filed a complaint with BBB and the Consumer Financial Protection Bureau to get the $2300 MPP warranty removed because I don't need a warranty when there is already a bumper to bumper warranty on there. I can just add the additional warranty when the original warranty expires. read more

My girlfriend left her 2024 GMC Terrain at McKinney Buick GMC for transmission repairs, and what followed was extremely concerning. Over multiple visits, the dealership misdiagnosed an active transmission leak four separate times, failing to properly identify or fix the issue. While the vehicle was still in their care for these transmission problems, it was taken without authorization and involved in a major accident. The vehicle was being driven late at night by a 16-year-old minor, with a McKinney Buick GMC service advisor as the passenger. The car was used for a personal errand unrelated to servicing or testing. As a result, the vehicle was damaged, and my girlfriend was forced to deal with insurance claims, police reports, and ongoing stress--none of which should happen when a car is left with a dealership for repairs. This situation reflects a serious lack of professionalism and responsibility, from repeated misdiagnoses to misuse of a customer's vehicle. I would strongly caution anyone considering this dealership to think twice before leaving their vehicle here. read more

I can see by the other reviews I am not alone here. We asked for the plugs and fluids to be checked for a rough idle. Specifically said ignore the emissions code that had been there for years. In short, we got an estimate for $7,000 in miscellaneous nonsense. We selected and signed off on an estimate for a timing belt and air filter only for $415. When we arrived to pick up they charged $633. A diagnostic fee I never signed for nor asked for was added on. Condescending service advisor and manager. I will tell everyone I know never to go to this shady operation. Avoid at all costs. read more

I have a google review from when we first moved to McKinney and continued servicing our 2018 GMC Yukon XL. Since then my husband & I traded for a lower payment and I now drive a 2021 GMC Acadia Denali. We have been pleased with our service here from the very beginning. The whole car sale experience as well as continued service & maintenance. Even if we came across issues, they were corrected whenever addressed. They move a LOT of cars buy/sell & service. Christopher Elliott and Willfred were SO helpful and I was notified of each step as my car was serviced. Also, No push back when I was declining a few issues that will be taken care of at a later date. Im very thankful for our McKinney GMC!!! read more

We purchased a used vehicle on 4/4/25. We were told if went through a rigorous inspection process and reconditioning. Less than two weeks of ownership, we discovered major issues with the motor mounts and the control arms that hold the engine in place. We also found rust on the spark plugs and on the battery terminals. Dylan Christian the manager told us that is what we should expect from an older used car. He also said they were not willing to do the right thing and a refund/return would cost them money! Worst customer service experience of my life! He was condescending and rude! read more

Mixed Experience - Proceed With Caution I've been a loyal customer of McKinney Buick GMC since 2021, but the service experience recently left a lot to be desired. I encountered repeated attempts to upsell unnecessary services, charges for work that wasn't actually performed, and quotes that mysteriously increased at checkout--issues that point to a troubling lack of transparency. That said, after posting my original review, John Smidt from the dealership reached out directly. He genuinely listened to my concerns and took steps to make the situation right, especially around the most recent issue. I truly appreciated his professionalism and willingness to own the problem--even if it came after the fact. Because of John's follow-up, I'm updating my review from 1 to 3 stars. While I still urge others to double-check pricing, ask questions, and document everything, I do want to recognize the effort made to repair the relationship. It went a long way. read more

I called in the morning and asked if a truck was still available for sale. I was told yes. I told them that I would come by later that afternoon to look at the truck. Before I left work early to go look at the truck, I called the salesperson again to see if the truck was still available. He told me yes. When I got to the dealership the salesperson brought (2) trucks out. Neither were the truck I had inquired about. I said, this is the truck I've been asking about. It was right there in front of me. He said oh...sorry that one has already had a deposit on it. The salesperson knew it and tried to bate and switch me, instead of calling me and preventing me from wasting my time. Very unprofessional. Very disappointing. I won't be back and certainly will not be recommending McKinney Buick-GMC. read more

My daughter bought a used car from GMC Pre-Owned. She was a first time car buyer and the "Dylan" the sale manager didn't like that we weren't using their financing. We came in with a auto loan check from our bank and and wanted the price off the internet. As we were walking out with license plates in hand, Dylan told us we had to wait for the cashier's check to clear from the bank and it would be 3-10 days. Today is day 10 and "later" is what they are telling us now. BUYER BEWARE OF GMC Used Car Sales. Dylan is the butt of every used car sales man joke. He really defines the negativity that we all think of when you say someone is a used car salesman. No apologies, or we'll do better. Just Dylan playing games according to another employee at GMC Used Cars McKinney. read more

One star. As a twenty-three-year law-enforcement veteran and United States Navy retiree, I arrived in McKinney after four days on the road with my family, expecting nothing more than a fair transaction. Mario arranged the visit. General Sales Manager Roderick Johnson shook my hand--first to me, then to my wife--and assured us the price was final after giving us numerous financial incentives. Five hours later, signed contract in hand, I drove to Wells Fargo. While standing in line, Roderick called: "We can't honor that three-thousand-five-hundred-dollar incentive." I looked at the paper. I looked at my eight-year-old. I left. I will never recommend McKinney Buick GMC. But I will recommend Ewing Buick GMC in Plano--where Bradley Atkinson and his management treated me with the respect I'd been denied. They gave me a straight price, a real handshake, and a truck in two hours. Not all GMC dealerships are the same. read more

Was looking to buy a used car from here. Don't live in the area and was working with a salesman (Angel) and a sales manager (Dillon) remotely on a deal to make sure it was worth the drive. After a couple of days and a lot of back and forth texts, we came to a compromise and a deal was made that worked for both sides. I drove all the way up to McKinney to sign the papers and drive the new car home, but after signing the preliminary papers, and moving on to the finance department to finalize the deal; the manager came back and said that he could not honor the deal anymore. He told me that he was going to have to raise the APR by more than 2 percentage points which would obviously raise my monthly payment by more than I could afford. Very frustrating since I live out of town and thought that we had a deal and even signed for it. They were both nice enough people, just not sure how they could allow that to happen after confirming with me and having me submit the credit app which affected my score.. read more

Purchased a 2025 2500 sierra Denali ultimate from this dealer end of may 2025. The day I purchased it I was made aware to bring it back that next day to align it and take care of a couple of things. I drove it one day to find out that the vehicle had radio issues , major alignments issues and a loud steering column noise that is very clear when steering left or right from the steering wheel column . I went back to have the service dept take care of this issues as i excepted them to be able to. After multiple attempts to the service dept. I was told there are no known issues and the couldn't replicate those issues reported . I was even told by one of their service floor managers "to take my truck back where I bought it from" knowing that I had purchased it from The same dealership. That showed me the low level of service this dealership has overall. It's a typical sell And run and avoid the customer when they need service , they never call back for status update on repairs "if any. My truck has been at the service dept for at least 4 months now, I HAVE TO CALL THEM to get status updates and when I do, they tell me to go test drive it as issues have been repaired ! I go to test drive and the issues are worse now , same noise , Bluetooth does not even connect to my phone or anyone's phone to that matter, alignment will even pull to the next lane now. Service director was in shock when he was roam the vehicle was ready and I test drove it with him and he was the one to tell me nicely to keep the truck with him again to make sure now GM is aware of it and that a repurchase claim to be issued at this point as they can't repair it ! The GM will never call to address this issue , the dealer owner will never reply to any call or email sent regarding this issue ! STAY AWAY FROM THIS DEALERSHIP, they're the typical USED CAR SALES mentality and very low class all Around, this dealership will have their name get smudged in the mud with reviews rather than servicing their clients . I met several clients at the service dept waiting area that are super frustrated with issues that have been lingering and never been taken care off . BEWARE AND GO ELSEWHERE FOR YOUR NEW TRUCK OR TO SERVICE YOUR VEHICLE. read more

I bought a new 2024 Encore from Buick Mckinney and it has beena horrible experience. The car is a lemon and they do not know how to fix it.

The sales side has been great, wanting to buy a new GMC 3500 ultimate. However, after dealing with Michael Deegear in the service department I don't think I'll be back. This guy was an absolute nightmare to deal with, he called me a liar, asked me why I'm still here, was incredibly rude. I'm not sure how he has a job with the word service anywhere in it... too be honest I'm not sure how he has a job. Acting like a Smart A$$ but not smart, rude and gross attitude. I have a brand new corvette and 2021 Denali 2500 and was about to add a a 2024 3500 but honestly im not sure after having been spoke to and treated the way this guy spoke to me.

do not buy from mckinney gmc! beware i am stuck with a lemon gmc they cannot repair .

This was my second time as a customer to the service department. This time for my Regal in need of a new car battery installation. Samuel was my service advisor once again and he was topnotch on customer service. We had just arrived in Texas and I mentioned that we were hungry. Samuel had the shuttle take us over to Razoo's to get a meal while my car was serviced. That was so much appreciated. Above and beyond. And the complimentary carwash removing all that dirt from my road trip was fantastic. Thank you McKinney Buick-GMC! read more

I have had my truck serviced at this dealership for several years. Unfortunately, today was not a good experience with the service manager, Rob. Very disorganized and not completely sure of what is going on in his service department. Even though he took my order, he claimed I lied because "he never talk to me at all today." However, his name is on my order and receipt because he did take it, and all of the documentation that I needed them to complete. They didn't complete the work requested, because he said I never made it clear even though the documentation needed for me was provided back to me, incomplete,when I checked out. I am guessing I'm not the only one who is experiencing this. This is the second time I've had incomplete service performed at this dealership. However, at least last time they were courteous about the situation. There are many dealerships, repair shops, and options of where to get service performed, and typically the difference is quality of service and reputation of the service team. This dealership took a big notch down with me today based on what I just experienced. I can no longer recommend them in good faith, even though I have sent a lot of business to them in the past. read more

FIVE STARS. Perhaps the ONLY honest dealership in DFW. Customer for 5 years, and I've seen it time and again. Rob Barth's service department has a culture of concern for the customer. Genuine concern. I've seen Rob tell the techs to do a service for free because a lady was caring for a family member and simply did not have the funds. They know I'll do whatever service they recommend. But, they always advise me what is truly necessary and what can wait. Very often, they say a GM recommended service can wait or suggest a plan to make the service efficient by doing it when something else is done. I have never brought my Denali in that they did not leave money on the table. These men tell the truth. Ask for Chris Elliot. He is no nonsense and not a salesman. He shoots straight and is super respectful. He treated me like a valued customer again today. He gave first-class service with attention to detail and complete focus on what was best for me. He voluntarily held the dealership accountable when a mistake was made. He went above and beyond. Thanks Chris! And thanks Rob for a shop where men like Chris can freely do right by people. read more

I want to begin by thanking several members of your team who provided outstanding service during my recent purchase of a 2025 Buick Encore GX on May 12, 2025 at the McKinney Buick. * Kendall Walton, Sales - 100% satisfied. Patient, respectful, and attentive throughout the process. * Gilbert Martinez, Finance - 100% satisfied. Professional, transparent, and supportive of my concerns. * Andrea Elguera, Title Clerk - Courteous and efficient, especially in helping with my veteran license plate transfer. * Roderick Johnson, General Sales Manager - Helped me understand the process of transferring my veteran plates in a kind and respectful manner. I appreciated the way he explained things clearly and patiently. As a service-connected veteran, I often approach large purchases with added caution and anxiety. I felt reassured and supported by your team, which makes this current issue especially disappointing. On June 7, I called the McKinney Buick GMC dealership to report that the paint protection film (PPF) on the hood and fenders, which I was charged $699 plus tax for, was never installed. During that call, I requested a refund. On June 14, I spoke with Mr. Roderick Johnson in person and showed him the missing PPF. On June 18, I followed up by email with Michelle Griffin, your Customer Relations Director, after receiving her message asking whether I was "completely satisfied" with my experience. I've made every effort to resolve this directly and respectfully. However, the PPF was included in the price I financed, and I am now paying interest on a product I never received. Had this missing item been disclosed at the time of delivery, I could have made an informed decision -- but I was not given that opportunity. I am therefore requesting a full refund for the uninstalled PPF. I respectfully do not accept post-sale installation as an adequate resolution. I emailed the General Manager, David Kelley, on June 23, 2025. I want to be clear that this message represents my final effort to resolve this matter directly. If the refund is again declined, I will escalate my concern to other appropriate consumer protection channels. I hope that will not be necessary, and that your team will choose to resolve this fairly and professionally. Thank you for your time and attention. read more

STAY away from this dealership at all costs. I inquired about a 13k used car with 95K miles on it and was quoted $2300 in make ready fees!!! If you want $2300 more for a car, add it to the asking price on the website!! Come on McKinney Buick GMC, do better and stop ripping customers off by making them pay for something that's YOUR responsibility, not the customer. People need to stop paying these bogus fee's.. Like I said, pick an honest dealer, not this shady place. There are plenty of honest dealerships in the DFW area. read more

Took a preapproval letter from cars.com along with all documents requested. The offer was $1500 down and $350 a month from a lender that I had used before and paid off a car. I drove over an hour to the dealership. They took the paperwork from me and insisted that I use their financing company. Another hour later they tell me they want $5000 and $499 a month. The total price on the car was $11000. It's misleading and very unprofessional. read more

Service department is horrible. My truck was towed in on a Thursday and was told that they would have it diagnosed by Tues. Tuesday came and gone and nothing. I spoke to the service advisor and he said they pushed it into a service bay that night which was a wend. Which is fine I was in the hospital anyhow. I drove by there Thursday morning my truck hasn't moved from the spot it was towed into. I get a msg on Thursday afternoon saying something about a guy causing trouble about my truck and they aren't gonna do work on it etc. lies I was in the hospital and this is my truck. So my service advisor Raul lied to me about it being in a service bay and found a way not to work on it. This truck has had this same issue and it never gets permanently fixed. I will never buy a GM product again and certainly not from this place read more

Stay away from this dealership. I never leave bad reviews publicly, but this experience was a nightmare. First, Patrick V. in financing flat out lied to us that all of the warranties are refundable. The Exterior Care Warranty was NOT refundable. We verbally verified with Patrick several times that all of the warranties were refundable and he assured us they all were. That was a lie. When we tried to reach out to the dealership to remedy this, they said "It's not refundable" and did nothing to rectify Patrick's lie. I see in other reviews here he has done this also to other people. Furthermore, we purchased our Yukon XL Denali used, (and the salesman was wonderful by the way), and as we drove off the lot we heard grinding/moaning noises indicating a problem with the rear differential. We immediately returned to the dealership and upon investigation, yes, the rear differential was failing and (after much painful back and forth and a standoff) they ultimately took responsibility and said they'd make it right. However, the service department refused to order a new part saying their protocol specified a fluid flush first. We live out of state and could not keep traveling back for repairs. They would not budge on the protocol of a flush first. So we got in writing that if the flush did not fix the noises they would install a new rear differential. The fluid was on back-order at the time and we were put on the waitlist. Ultimately, with no updates after 2 weeks, we ourselves called around and found the fluid available at a neighboring GMC dealership to McKinney and arranged for that fluid to be used for our car. The McKinney service department called us after the flush and told us the car was "fixed and ready for pick-up". We drove from out of state to pick up the car only to find the issue was NOT fixed, the sound was still present. They wasted our trip when even their own service paperwork listed the sound was still present. We pulled out our "WE OWE YOU OWE" document to have the rear differential part ordered. The service manager refused to honor it but his director upheld it. We were put on a new wait list for the back-ordered part. (This could have been expedited if they'd skipped the flush and not insisted on a useless protocol procedure.) The part was finally shipped 6 weeks later, only to be "lost" in transit. We were dropped to the bottom of the back-order list AGAIN and continued to wait. I'd called GMC Customer Care for help but found out, after back and forth with them for 6 weeks, the wrong department took my case and ultimately said they could not help me. And, because the wrong department took our case, it used up our allotted timeline of getting help through Customer Care. After 3 months of paying interest, insurance and car payments on a car we never took home, the part finally arrived and the car was repaired. When we got the car home finally, our local mechanic found the rear struts had been leaking for quite some time and were badly in need of being replaced. This was NOT disclosed at the point of sale and should have been obvious at their inspection for resale when they are listing the condition. There are a lot more things that happened along this 3 month nightmare with McKinney Buick GMC, but my main complaint is being lied to about the warranty's refundability, the car's mechanical integrity not being assessed or disclosed properly, and the absolute headache of working with any management who would shuffle us to other departments and say it wasn't "their problem", and no one using common sense to adapt protocol steps to a more timely resolution when the customer lives out of state. Ultimately our car was out-of-service for 3 months since the time of purchase. We were even told at one point by management we needed to "take personal responsibility for buying a high mileage vehicle". The vehicle made the noises as we were driving off the lot, how is this ever okay to say to a customer? We will NEVER return to this dealership and strongly recommend against using them for purchasing or service. read more
