my experience was good, the finance department was fast, the deal was worked over the phone as I didn't want to waist time working a deal. It took me 2 hours tops to sign and get out of the dealer. Marvin Tejada was great sales person and John and Leslie where great helped negotiating. Marvin explained some features on my suburban and John took the time to explain the system on the dash board and I left super happy bumping my music lol. My drive with my new suburban up the mountains was the best drive ever. read more

Got spam mail with handwritten personal information, completely unprompted, talk about a major eye roll. I hate companies that waste paper and personally headhunt unsuspecting people in the mail. Nothing new, just another company soliciting and wasting time, money, and effort. read more

UPDATE: We STILL have had no further communication from this dealership. After months of trying to get a response, Patricia finally called us on 4/1/26 and assured us she would follow up by Friday, 4/3/26. Unfortunately, we have received nothing since. I have called, left multiple voicemails, and sent three emails with no response. I genuinely do not understand how a business can publicly respond to a review saying they are "looking into the situation," yet fail to provide even a simple update directly to the customer. At this point, I am asking again: what exactly are you "looking into"? Patricia already confirmed that we were charged for a service that should have been covered under warranty. In addition, your team improperly installed our exhaust pipe, which led to further damage and required a full replacement. We have documentation from another certified Chevrolet dealership supporting both of these claims. We are simply asking to be made whole. Please refund the $2,553.42 for warranty-covered repairs, along with the $1,373.40 in additional repairs caused by improper installation. If this is resolved promptly, we are more than willing to remove our negative reviews and move forward. However, continued lack of communication only reinforces our concerns. read more

I do not recommend this dealership based on my recent experience. Unfortunately, I left feeling that making a sale was more important to them than actually taking care of a customer who was dealing with a serious problem. read more

Got a used 2022 Silverado. 6 days later, took it back to the service department. 6 days later, no communication, no update, no loaner. Spoke to the service advisor once after going in the second day of the truck being there. Left several messages, no calls back. Getting transferred back and forth from, ending on a line with no voicemail option so lucky for them it hangs up. I regret ever coming here. This whole experience sucks. This was a gift for my husband for Father's Day. What a gift! read more

I have now sent two separate emails, one responding to the manager after my initial review, and another a week and a half ago explaining I will now be pursuing legal action! Dodge told me to take my car back to the dealer I bought it from before even more things happen!

I expect a resolution before I Contact the dmv and the BBB read more

Had the best vehicle purchasing experience in my life. Tim Kubo at Diamond Chevrolet is a world class professional. I got exactly what I needed with no hassle the sales process was so simple here. Had very minimal wait to go sign all the documents. Tim made this literally the smoothest vehicle purchase I've done & I buy a vehicle every couple of years. Will definitely be back & will refer him to any friends relatives coworkers who are in need of a vehicle. read more

Diamond Chevrolet - Look at that Sexy thang!!! Thank you Tim - Car Dealers Near Me - San Bernardino, California

had a very bad experience with Diamond Chevrolet and would not recommend their service department. Before bringing my vehicle in, I specifically called and asked how much the diagnostic would cost. I was told it would be about $280 and that after the diagnostic they would contact me with the repair cost so I could decide whether or not to continue. After keeping my vehicle for two days, Alan called me and suddenly said the diagnostic would cost $1,200. I immediately explained that this was not what I was told and will not authorize a $1,200 diagnostic. Instead of trying to resolve the issue professionally, he became upset and told me the car would be ready in about one hour. I showed up over an hour later and my car still was not ready. Because of this delay, I ended up being late to work. Nobody seemed to care about the inconvenience or wasted time. The whole experience felt misleading, unprofessional, and poorly handled from start to finish. Customers deserve honest pricing, accurate timelines, and better communication than this. read more

1 Star - I will not be returning to this service department I reluctantly gave Diamond Chevrolet of Banning's service department a second chance after a poor experience over 1.5 years ago. I live in Beaumont, so Banning is convenient, and they were advertising an oil change special for Corvettes. Unfortunately, my second visit confirmed I should have trusted my first impression--this service department is unprofessional, unfriendly. The appointment: I booked online for 3:30. I arrived on time--no cars in line, no customers waiting, four service advisors chatting about personal things. I stood there unacknowledged until finally someone waved me off with a "one minute." Tyler, the advisor, eventually helped me but with zero professionalism--no eye contact, dismissive attitude, and made me feel like I was interrupting him. The pricing & coupon issue: When I told him I booked the online oil change special, he insisted I "needed the coupon" and wouldn't even look it up himself. After fumbling on my phone to show him, he finally accepted it but acted annoyed the entire time. The oil mistake: Almost three hours later, I was told my car was ready. To my surprise, they put in Dex1 oil instead of Mobil 1, which is what my Corvette has always used. Only when I questioned it did Tyler point to fine print on the special. He never mentioned it beforehand, and when I asked to speak with a manager, he literally turned in his chair and said, "He's busy." Only after I pushed did the service manager, Mike, finally step in. Mike at least listened, admitted the issue, and promised to swap the oil for Mobil 1 if I brought the car back. The follow-up: I returned at 7 a.m. the next morning. Again, I got Tyler. He seemed uninterested, barely recalled the situation, and then told me they were "out of Mobil 1" for my car. And if I wanted to wait while they go get the oil for my car. After another hour wait, they finally swapped it at no charge, which I appreciated--but the frustration, wasted time, and dismissive treatment far outweighed that small courtesy. Bottom line: From being ignored when I arrived, to dealing with rude and disengaged advisor, to having the wrong oil put in my Corvette yes I understand I am to blame as I should have read the small print but I also feel Tyler as the service advisor should have caught this. this was an exhausting and unprofessional experience from start to finish. Mike did the right thing in the end, but the fact that I had to fight to be treated with basic respect speaks volumes. I should have trusted my first experience and not returned. I will not be coming back to Diamond Chevrolet of Banning's service department again. read more

Dylan(Cowboy D)made the car buying experience something that was not stressful.

Joseph Gotti is a fantastic salesman! He was very knowledgeable on various offers and inventory and personable which made the typically long process of buying a vehicle seem much quicker. He worked hard to get us the best deal on a very sought after 2500HD diesel truck. We hope to be back for near future purchases and will go directly to Joseph! Thank you! read more

My 22 Traverse had an exhaust bracket issue which was covered under Chevy warranty. I called the morning of and was able to get an appointment that morning. I dropped off my car with Alan and he was a pleasure to work with. Made check in easy, kept in communication with me about my car, and was able to pick it up the next day. They replaced the exhaust at no charge. I was very impressed how easy the process was and to get my car back quickly was helpful. I would recommend the service department at this location. read more

Very disappointing dealer. They load their cars up with every conceivable extra, paint protection, key protection, GPS, brake light BS, ETC., and you have no choice but to pay them the extra $. My car did NOT even have the $695 brake light extra installed on it. After calling 5 times to resolve the issue they just ghosted me. This dealer lacks integrity and is only interested in getting every dollar out of a one time deal. I'd never return to this dealer nor would I recommend this dealer. They give you your paperwork on a thumb drive. My thumb drive did NOT include any of my purchase documents. When I called about that, I was again ghosted. Avoid this dealer at all costs. read more

Today I came in for an oil change and was sold a new Chevy Suburban by Joseph Gotti, he did an excellent job at finding me the car I wanted with all the features plus some. I really appreciate his help. I highly recommend him and this dealership (Diamond Chevrolet San Bernardino). read more

For me, Service after the sale is Key when it comes to picking a Dealer. Diamond had a great Value coupon mailed to us for an Oil Change. Their Dirty facility (Customer Lounge) and poor Customer service made us realize why the Coupon was needed to draw in New Customers. After this experience, we won't be going back. Anthony in service was less than friendly and ensured the bad review with the added wait time of almost an Hour after the work was done. (Processing Paperwork for an Oil Change takes an Hour?) Never again. read more

Sales process was absolutely horrendous. Since buying the truck, it is virtually impossible to get ahold of anyone there. No customer service at all. Highly advise people to buy their vehicles elsewhere. read more

Update: Go to Tom Bell Chevrolet (Redlands) instead. Helpful, friendly, and did a GREAT job. Avoid Diamond Chev at all costs. Updated Review: 11/12/2025 1-Star Rating still valid Took my CHEVROLET truck in for service. They declined to even look at the truck and informed me that they only service new vehicles. I even made an appointment online and they knew what year it was before I brought the truck in for service. Service advisor was rude and unhelpful. Three strikes. Will never do business with any of the Diamond dealerships again -- including for my 2023 Honda Ridgeline. ---------------------------------------------------------------- Second strike. Won't go back for a third. Brought my truck in for service. They gave me a $900 estimate for new distributor and coil. What they didn't know is that those components were replaced approximately 9 months prior. Problem was actually the ignition module. Bad diagnosis would have cost $900 more than necessary. I suspect that because it is an older truck, that Crest Chevrolet is more interested in selling me a new one than servicing the one I own. This is the second time the service department has shown a lack of interest in maintaining my truck. Fortunately, Tom Bell Chevrolet is not far away and, so far, their service department has been great and wants to help me keep my truck on the road. [Update: Tom Bell Chevrolet found the real problem right away - a $40 Ignition Control Module needed replacing. Now the truck runs great again at a fraction of what Crest wanted to charge.] read more

Truck was there eight weeks getting the transmission serviced got a back worse than before. Red lining paid for a oil change that was never done. As for my money back told me that they would send me a check that they cannot refund me my money in cash never received the check the supervisor Hector said I would have my check for my refund on my oil change since it was not performed in the next two days and it's been a week and a half everyone best advice I could give to you stay far away from diamond Chevy of San Bernardino. Also, I bought the truck in November. It stayed in service for two months now I took it to another Chevy dealer. read more

This was a WILD, CRAZY, and EXCITING moment for me and my family! We had been looking for a used car because we believed we would never be able to get financed for anything brand new, we've been driving a 2008 Honda Civic LX with 214,000 miles on it. it still runs, but it is getting old and it is ready to retire. We knew we needed to buy another car. We just knew we'd have to buy another old car with probably a lot of miles so I've been looking for like the last three months and I happen to come across Diamond Chevrolet Of San Bernadino. I found a car I liked but it was on a different lot, I was working with Timothy and Luis at Diamond Chevrolet, I don't have the greatest of Credit either does my husband that's why we knew it was possible to buy anything new. So as they were working hard at getting us approved that car had fell through and so Timothy suggested why don't you try the 2025 Chevrolet Trax we could get you in that with no problem. I said I don't believe it but you could try if you want so Sam another manager there started working the deal in less than an hour. We were approved for 2025 Chevrolet tracks with 4 miles on it. I could not believe it. They had the car ready for us washed, cleaned everything and we drove down there and it took less than an hour to sign our papers and become happy happy Chevy tracks owners I never in my wildest dreams would've thought this would've happened. I cried. I'm still crying now. They made this process so easy and even with not great credit or terms. I cannot say thank you enough to Timothy Luis and Sam thank you so much for making our dreams come true. I hate dealerships. I always have I stay clear of them and away from aggressive salesmen. They were nothing of that sort. They were patient understanding and really worked hard to get me the car that I deserved and wanted and didn't expect. I'm so happy thank you guys again for everything. read more

I am a loyal customer and Diamond Chevrolet of San Bernardino is a horrible place to take your vehicle. I took my 2019 Chevy silverado1500 LT in for my AC compressor to find out my transmission was bad. When I dropped my truck off I had no oil leak problems. Now they are telling me I have an oil cooler leak. They won't take responsibility for it. They've now have my truck going past three months. I call for updates on my truck, I can't get a hold of anyone. To have my truck for this long is very unexceptable business. I'm very disappointed on how they treat very loyal customers. I will never go back and I will be telling my buddies at work and anyone else willing to listen. Hopefully I can save anyone else from having this headache. read more

Thank you Armando and Alan , I love coming here they have fast service and customer service is definitely amazing .

We just had another amazing experience with Diamond Chevrolet in San Bernardino, and once again, Gotti went above and beyond. He recently helped us get an incredible deal on a brand new Silverado for my son so he can have his first truck. Gotti made the entire process smooth, stress-free, and honestly enjoyable. We are repeat customers and will always come back. He listened to exactly what we needed, answered all of our questions, and truly cared about making sure we were happy with every detail. It's rare to find a salesperson who's this genuine and dedicated, he treated us like family, not just another sale. If you're looking for a vehicle and want someone who will actually look out for you, go see Gotti at Diamond Chevrolet. We couldn't be happier with the experience, and our son is over the moon with his new truck! read more

Had a really good experience at Diamond Chevrolet, Elizabeth was great from the start to the finish. I made an online request for some information about a vehicle that I was interested in. Elizabeth called me right away with all the information that I needed and I made an appointment right away for a test drive. The vehicle was just what I was looking for and she made the process go as smoothly as possible. I would recommend this dealership and definitely working with Elizabeth, she was very helpful and knowledgeable and made this a great experience. read more

Never getting a vehicle from here again since I got it it has been headaches with them they couldn't submit the transfer papers to the dmv correctly so now I have to go and waste time again like the two times I had to go cause they sold me the vehicle with bad parking sensors then a 3 weeks later the battery went bad and the sold me the vehicle with the front camera damaged read more

Service department- Should be no stars! Brought our truck in to check transmission. They said it needed a new one and it would take no more than 2 weeks to replace. We gave them the okay and it took more than 6 weeks for them to complete and had terrible communication the entire time. We would have taken it somewhere else if they would have been honest with us. After they started and were way beyond 2 weeks, they told us they were understaffed in the service dept and there was nothing they could do. And now less than a year later we are having trouble with a temp sensor in the new transmission that another Chevrolet dealer told us they should have replaced already when they installed the new transmission at this dealer. So now we're paying another dealer to replace the transmission temp sensor and all the labor to do that when it should have been done already per another Chevy service dept. And had that part wrecked our transmission the 3 year warranty we had would have been void because this part was not replaced, how convenient for these crooks! We paid a premium at this dealer to get a top notch job, and instead I should have taken it to another dealer or transmission shop and saved my money and gotten it done in a timely manner and gotten it done properly. Never taking our trucks to them ever again! read more

Horrible service horrible customer service and that's thanks to diamond Chevy San Bernardino bought a 2022 Chevy Silverado couple months ago transmission already went out. It's under warranty. It's now five weeks without my truck. Getting the constant ignored no callbacks messages left on read and a whole lotta excuses. Why the trucks not done.

Had an appointment today and was told it would be about an hour and a half. After an hour and a half I checked on my vehicle, they said it was in the service bay being serviced, and would be done shortly. After two hours I checked on my vehicle again, and I found out it had never been in the service bay and was never moved. I understand it can get busy but that was the whole point of making an appointment and to tell me it was being serviced when it never was....wasted two hours of my time for nothing read more

They basically are the reason for the stereotype of used car salesmen. Don't waste your time trying to sell your car to them they will not honor their cars.com offer price but will make excuse after excuse why they won't.

Caution. Make sure you talk to your service rep. Directly when it come to concerns or updates. I dropped off my truck for some overdue recalls, two days before my appointment I noticed my adaptive cruise control. My truck was not functioning. Since I was dropping off my truck, I asked him to take a look at it. $250 to get it diagnosed they told me. I said that's a little steep but OK I have to get fixed right so I agreed with it. As I left the dealer, I talked to a buddy of mine that told me he had the same issue with the adaptive cruise control. He told me that if my windshield had cracks or chips. It might be the cause of the adaptive cruise control not to work. So literally 20 minutes after I dropped off my truck I called the dealer service operator and let them know that I did not want my truck to get diagnosed for the adaptive cruise control. She told me that she would let my service department representative know. Well, she never did when I came to pick up my truck a couple days later I still got charged for the diagnosis. even after I showed him the call log on my cell phone. They told me I still had to pay. come to find out that when you call this dealer, your call goes to an out of the country call center. very thick accents can't understand what they're saying. They can't even understand what you're saying to them so please be aware. read more

Two words for this service department lazy & shady! (For the office workers. The guys outside look like they are hustling!) It took them over 30 minutes after my oil change was done to get the paperwork done. Ridiculous! I even asked what was taking so long 3 times And they just sat around talking and taking their time. Finally got my paperwork and it was $30 more than the original paperwork that gave me. Then the girl got upset when I called her out on it. They still charges me $20 more than the original invoice and tried to act like they were looking me up by taking the $10 off read more

I found out that Diamond Chevrolet uses "bait 'n' switch" as their business model the hard way. I was interested in their Equinox EV lease deal $149/mo + $2,999 down for current Bolt owners. I drove 77 miles in my 2018 Bolt Premier (68k miles, excellent mechanical, decent cosmetic) after talking to them for 10 days about the $149 deal and being told "yeah, we'll definitely buy that car," "you could probably get over what you want for it," and "our used stock is low." I owe $11,600ish on it and that's what KBB value is, so I figured this would be a done deal (or not hard to figure out). When I got there, there were no models with the options I wanted (I had spoken to two sales reps that never indicated this would be the case). I should have taken that as a sign...it turns out they wanted to give me $7,400 for it ($8,000 with pushing) and boost the monthly payment to $588. After thinking about it, I'm not sure how it's mathematically possible that being off on the trade in by $3,600 would drive the monthly payment up over $400. In no way did I think this was going to be the case; I was upfront with everything about my car in our conversations. I thought they would have been eager to make a deal, considering I followed their site for over 22 days, and none of the 15 Equinox EVs on their lot sold. Definitely soured on this dealership and Chevy in general after this. read more
