I brought my 2019 VW Passat to Midas in Diamond Bar, CA for an oil change, and the experience was outstanding from start to finish. Right away, the staff was friendly, professional, and respectful of my time. The shop was clean, well-organized, and clearly run by people who care about their work. The oil change was completed efficiently, and everything was explained clearly--no pressure, no upselling, just honest service. A special shout-out to Eric Waltz, the Service Manager, for his exceptional customer service. Eric was knowledgeable, transparent, and made sure I felt confident about the work being done on my vehicle. It's rare to find a service manager who is both professional and genuinely customer-focused, and he sets the tone for the entire team. The rest of the staff personnel were equally impressive--courteous, attentive, and easy to work with. It's clear this location values customer satisfaction and quality workmanship. If you're looking for a trustworthy place for routine maintenance like an oil change--or anything else--I highly recommend Midas of Diamond Bar. I'll definitely be returning for future service.

Never again. I have been going to this Midas for years. It was great. Then Mr. Patel retired. My last two visits were a total of $4,100. I own two well maintained Hondas, which are supposed to average $600-$1,000 maintenance per year. I am now looking for a new, honest auto shop. When I searched online, AI explained that Midas in NOT known for being a very honest business, and that you are wholly reliant on the manager's professionalism and ethics. I gave them 2 stars because they are courteous and professional while gouging you. : ( read more

Your favorite Yelp correspondent happens to be nearly stone deaf without his hearing aids, so when my beautiful bride told me that my brakes were whistling on date night last night, you can bet I was up early, primed to get my brakes checked out. I don't know about you, but I regard taking my car to a mechanic as a chore on the order of a root canal or watching my beloved Trojans blow a winnable game. So I took the necessary precautions before arriving at my neighborhood Midas- I fortified myself with a stout bowl of Wheaties and took an antacid, half bracing myself for the inevitable bad news. And HERE, my fellow Yelpers, is where the story caroms off script quicker than your favorite bank heist film! Thanks to manager ZACH THORNTON and mechanics like DEVIN, I actually received an honest appraisal and ZERO CHARGES. How's that for a great value?! The issue that was likely causing the minor squealing noises that Leti heard? From a rotor-thinning (remachining) job that was performed a month before I acquired my Highlander. In nearly forty years as a driver, this is only the second time I've ever departed an auto shop without a noticeable limp, my face contorted with a sour countenance. The friendly demeanor and honesty exhibited by Zach and his staff are so refreshing in today's dog-eat-dog, prioritize-profits-over-people culture. I was in and out in approximately 90 minutes. In closing, if you want the PEACE OF MIND of knowing that you're dealing with an honest broker who will treat you fairly- Entrust your carriage to Zach and his team of automotive professionals at Midas, Diamond Bar. read more

Got my van for an oil change at this location. Pretty easy to get an appointment and very efficient on notification of the appointment. There is a Groupon special for oil change on your car or van. Follow the instruction to get an appointment after the coupon purchased. Nothing sure about other services but the regular maintenance is fine. Zack checked us in and you can see the work bay as you're waiting for your car for services. read more

I had an oil change done on October 22, 2025, and unfortunately I later discovered a serious issue related to that service. The drain screw/plug was not properly tightened after the oil change, which caused oil to leak from my car. I didn't notice the problem earlier because I don't know much about cars and trusted that the service had been done correctly. My family noticed oil on the garage floor where I park in February 2026, which is what first made us realize something might be wrong. On March 3, 2026, I went to another mechanic for an oil change and tire rotation. That's when the mechanic checked my car and told me that the drain screw from the previous oil change hadn't been tightened properly. He also explained that this could have caused serious damage to the engine. He also advised me to go back to the original shop and report the issue, because if the engine ends up being damaged due to this mistake, the auto shop that did the oil change could be responsible. When the oil was checked, there was only about one quart left in the engine, which was very concerning. This is a basic step during an oil change, so it's disappointing that something like this was missed. Because of this experience, I personally would not trust this shop with other services in the future. I hope they improve their quality checks and are more careful when completing routine maintenance so this doesn't happen to someone else. Also, I paid full price for the service (not with a Groupon or any discount), so I expected the work to be done properly and carefully. read more

2020 Chevy Express 2500. Came in because I had two squeaks: one from the engine and the brakes. I replaced the serpentine belt and front brakes elsewhere. I asked them to look into it found the reason was due to aftermarket belt and tensioner. Was honest about needed repairs and fair pricing. Took care of me same day. No more squeaks! Jonathon was the one I interfaced with throughout the process. Simple and straightforward. Plan to come back for future needs. Highly recommend. read more

Can't recommend this business highly enough. Service was quick and fantastic quality. Eric auto applied a discount for me as well and gave me some pointers on care that I should address soon with the dealer (since it might be under warranty still) rather than trying to insist it be done with him then and there. Really honest guy and treated me like I've known him for years. read more

My engine overheated and I was able to get my car checked the same day. They priced me fairly and was able to fix my car! There's also warranty on the labor, so I think for 90 days if anything pops up from their job I can bring it back. Zach was very helpful and knowledgeable. Would come back! read more

Eric was new but he and the team got the oil change done in less than an hour, less than he said it would take. Quick. Concise. Efficient. Bro got it done. 5/5 read more

Had an appointment for my son's car and my wife's car for 8am oil changes today. I had to take the day off to arrange this because my wife and my schedules are opposite. Drove 3 cars there from the neighboring city in order to drop those 2 cars off for the day, only to wait for 45 minutes for someone to open the store. I called multiple times and nobody ever answered or opened the store. We finally left assuming it was not going to open for the day. I called at 9:15 and the manager Zach answered. I asked what time they open today and he said, "well we were supposed to open at 8 today but I slept in." Then told me to have a good day. He didnt care at all how that effected our day. Glad you got your sleep Zach. You wasted my whole families time, money, and gas. We and nobody I know will ever go here again. How do businesses like this stay open? Crazy read more

Eric was a great help to getting my brakes done. He showed me everything I needed to make sure they weren't overcharging for anything unnecessary. Very trustworthy shop. Would definitely recommend read more

If I could give this Midas 10 stars, I absolutely would! The service here is the main reason I keep coming back. The staff is always friendly, professional, and always ready to help. I know I'm getting top-notch, quality work every time, and the best part is, they aren't trying to upsell me on things I don't need. It's so refreshing to have a shop that's genuinely honest, focused on doing great work, interested in making sure that I am educated on what is happening to my car and what needs to be fixed. Highly recommend for anyone looking for reliable, trustworthy car care! read more

I saw a Groupon at a great value to change my oil and rotate my tires. It said to make and apptmnt. I spoke to Zack and arrived at the right time. Even though 2 people were out with injuries he did the work himself while he contacted someone to come in to help with the office. Even with the stress of the situation they both were wonderful. I loved that they do a print out for me on other items that need attention. Also they put on my phone the picts he took of the actual part of my car. WOW. Smart Zack, you deserve not 2, not 3 but 5 special gold stars and 2 extra ones for keeping your cool under difficult situation. With my Groupon it cost me just under $17.00 and it was done in about 1 hr. Yes, I shall be back later for the other items that need attention. And Thank you. Donna R. p.s. They called a few of the clients that were to come in later to reschedule because of the lack of mechanics and to not cause the people to have to wait for a long period of time. I liked that. They care about their clients. read more

I was sent to this location by my warranty company to fix the issue with my car doors. I spoke to Jason and was VERY UNPROFESSIONAL. They had my car for 2 days and he had let me know that he would call with an update. I never heard from him, so I called. When he answered the phone he said "what's up". I asked for an update on my car and he said that they would have to keep it for another day. Again I called the following day, only to be told that it was too complicated for their mechanic. Disappointed in their service, professionalism and knowledge. Would not recommend taking your car there. read more

Fast, easy, and great service from Zach and his crew. Zach was a very honest manager that really cared about me and the other customers I noticed come in. Super friendly and professional. His honesty about pricing and what kind of work would need to be done was not only really helpful but sincere in that I know I wouldn't be taken advantage of. Will definitely be coming back for all my tune ups and check ups. read more

I would NOT go here if you are a young woman and don't want to get scammed of your money. Nice people but they definitely over charge you and you can find great service elsewhere. I got my spark plugs fixed then a couple months later my engine light came on again. They have a warranty so i took it back to them for them to fix. They were trying to charge me again for spark plugs when it should be covered under warranty right? they saw a young girl and thought they would get me with charging me but good thing i said no and i actually went to Auto Squad Repair and they helped me and pointed out to me that they were trying to charge me again for they issue they should've fixed the first time. I would not recommend coming here and I won't be back. Went to Auto Squad Repair across the way and they were sooo helpful and honest! read more

Great timely work was done on my car. I ran over a pallet and busted my tire. They fixed everything including the damage under the car. The manager was kind enough to drop me off & pick me up. This place provides top notch quality service. They were conscientious of costs as well. There is a new owner who provides fantastic customer service. Highly recommended! read more

I started coming here in 2013, shortly after moving to the area. I began using them for simple maintenance - mileage servicing, oil changes, etc. They were always up front about what was wrong with my car, and perhaps more importantly - what was not wrong with it. I've never been pressured into an up-sale. When I bought my challenger, I took it to the dealership for it's first (10k mileage) service, and had a horrible experience. Since then, I've used Midas in Diamond Bar exclusively. The third vehicle I had them take care of was a Toyota pickup, and I had them give it a full pre-purchase inspection for me. They gave me an itemized estimate, including noting how urgent each repair was - I used this to negotiate a fair price from the seller. I wish I would have been able to have them inspect my newest Dodge, which I purchased from back East this weekend. I brought it in today for oil change and inspection, and again - they found the issues, gave me fair pricing, and let me know which items were urgent and which were not. They finished the urgent problems the same day, and they'll take care of the rest at my next mileage service. I'm very confident that I won't have any surprises between now and then. They've helped me maintain vehicles well past when I thought I would have to get rid of them - my first two had a combined total of about 550,000 miles before losing them to collisions. Nitin has earned my trust and respect, and his mechanics have never let me drive off without being completely satisfied. read more

Not a trustworthy place to go if you are a young women. They will take advantage and charge you a higher fee for and oil change. My daughter went to get an oil change, we had checked the website and the price they promote is $27.99, when she got there the tech didn't give her prices or any information. Once the service was done she got charged $47.99 for a synthetic blend on a Honda civic. My daughter mention the coupon and the tech told her it was no longer valid. read more

I went here already before the new management, but this was my first time since the new management took place and they were really nice! They took in my car last minute and found a cheaper part that helped fit my budget! Overall, they were very kind, professional and very helpful! read more

Highly Highly disappointed with the Customer Service and price. Today just now , I got a pin on my tire and I called them they said come and get fix. So I went there and I walked into the store I saw a man with a pink shirt was siting there and I said hello and he didn't reply me anything and ask me which tire and I showed him the left one at the back. So he looked it up and said 35 dollars. I immediately told him 20 dollars ok? He was like 'no .. No .., LEAVE now' leave now !!!! I was shocked !! How on earth in this country like this kind of service giving enterprise would be so unprofessionally treating a customer like this. I am so disappointed! I rarely rarely write a review but this is unacceptable! read more

What a bummer. Went in to get a brake estimate, had to pay $10, with the guy behind the counter being very over-bearing and forcefully telling me "We all gotta pay up!". Okeee then...moving on to the actual inspection, I was quoted an incredible price of nearly $700 to replace my front brakes and rotors. Being that I usually replace them myself, I know the rotors were new 4 years ago and I probably had another 7-10 k miles on the organic pads I had installed. I asked to see for myself what they claimed were "unrepairable" warped rotors and pads worn down to the metal. What I observed were evenly worn, and not deeply grooved, wear on both rotors, with about 6 mil of pad left on each side, well above the indicator. They claimed both calipers were faulty and had to be replaced (?!?!?) with brand new ones. There was no indication of sticking calipers, and I knew these guys were scamming me. They wanted to do a complete rebuild of my front brakes when my car needed turned rotors and new pads. I went back in the office and asked for a detailed estimate and was refused. I paid the (now) $20 inspection fee and got a printout that said "Front axle brakes" as the item, and a hard, hard sell by the rude guy behind the counter, telling me I was leaving in a "death trap" and he was not responsible. This must work on unsuspecting customers, because he was not giving up, and seemed like he was used to bullying people. As I walked out of the shop, he was still yelling that we "all gotta pay". I went the following week to another auto shop in Chino, who gave me a reasonable estimate of $220 to turn the rotors and replace the pads. Unfortunately, when inspecting the car, I found a nice long, somewhat fresh cut on the top of my CV boot on my left wheel. I'm pretty sure this came from Midas when I refused the insane estimate for work my vehicle didn't need. Buyer beware, this shop is one to avoid. read more

WORST CUSTOMER SERVICE EVER ! Let's just say I had to get the police involved to get my car keys back !!! DO NOT GO TO THIS SHOP ! They'll have you chase problems for days until you drop few thousands replacing things that don't need to be replaced. The manager is a piece of something inhuman! read more

I have been going for 14 years and I exclusively bring my cars here, including purchasing tires. The service is always good and honest. They always take responsibility (not that there is much need for that as the work is good). I have found no unnecessary up selling. The price is fair, they will not drop the quality of service to get another customer, but they have not gouged me either. If you are a good customer, you will do great by them. read more

I had to take my car back 4x's to get my brakes fixed, even though I took my car back 4x's my brakes still makes noise. I called owner Neiton one more time about the Noise, and he told me he "I didn't want to see me anymore, don't come back. I spent $2,500.00 for brake job, spark plugs and oil, transmission and brake fluid change, and 4 struts, because he told me I need all this work. Now after spending all that money I needed a life time warrant for my brakes. I came to find out from the last brake job. They didn't change out the rear drums I, but when I went back this time they changed it, but my brakes still makes noise every time I apply them. read more

Yeah. I take back my Compliments. Service feels mediocre based on quality:cost ratio and the energy over the young mechanic(s), I think it gives off the vibe of taking advantage of people who don't know any better. It also doesn't help that they are always on their phones until the manager guy who speak with the customer says something to them. They feel robotic and quite frankly come across unreliable. I will say that the energy still feels friendly for the most part, but it feels off at times and comes off more just as a front to take advantage versus just being polite. I really wish I didn't think this way with the subtle hints, I just won't likely come back anymore. read more

Called for a price on a tire patch which should only cost literally from 15-25$ being the most. The guy who answered the phone seemed as is he already woke up in a bad mood, if your gonna be answering phone please have someone who is polite because they will drive all your customers away. At that point it wasn't the price it was the attitude of the person behind the counter. All I needed was reassurance on the person who is working on my vehicle and with that kind of personality I could tell they were going to overprice just to make a profit. I understand they aren't in control of the price but they are of their attitude! read more

Simply RUDE. Accused me of not showing up for any appointment when in fact I showed up on time and they're the one who only have one mechanic and was told they can't work on my car. To set another appointment. Now that I'm calling to set up, accused me of not showing up and just hung up on me while I was still explaining. So I quickly called again in a courteous tone to say never mind and I'll find someone better, hung up again. Nice for your business! Remember Being respectful and courteous is also part of it!... read more

Horrible place if I could leave a negative star review I would , I went to get my tire patched and he tried to charge me 35 dollars , and try saying the dealer charges 60 I left in a heart beat and went to auto zone and spent $6 dollars and patched it my self , read more

Nittin and the others at Midas in Diamond Bar are the best. They are very thorough in their inspections and are honest in their recommendations of necessary repairs on vehicles. I've been using their services for many years and recommend them to close friends and family. They take your safety seriously and make it a point to communicate possible upcoming maintenance. They are flexible with drop off/pick up times. I really don't go anywhere else for servicing. read more

I took my car to this Diamond Bar location a few weeks ago for just an oil change bc I had a coupon. He told me that I also needed brake pads desperately and he needed to change them asap. My car sputtered and shut off on Saturday. I checked the dipstick and the oil was completely dry. I took it to my real mechanic (Mandalay Auto) and he said they didn't put a filter plug back in that should Never be taken out for just an oil change. He also said my brake pads were totally fine! Rip Off Artist, Incompetent Mechanic and Shyster. F off with your reply to this review. He'll be lying (as usual) anyway read more

Called in to see if I can get my oil changed without an appointment and the nice man, Nitin, said if I can get here in 10 minutes they can fit me in today. Luckily this place is close to my home so it was very convenient to be serviced without an appointment. Very nice customer service so I will be coming back read more

The Indian dude is rude AF. When I walked in he looked bothers already even though there was only one guy in there. I asked him about the 49.99 oil change special. He quickly brought up the small print and extra charges; which I was fine with. Then I asked if it comes with a tire rotation but he assumed my tires needed to be replaced so he said he would not rotate my tires. I decided to take my business elsewhere and I advice you to do the same.. read more

They were able to assist me in the change oil service in no time. Superb service and gave fair price. Kudos to the team!

I was recommended by Costco to come here as part of their partner program but I think they should find another shop to partner with. My experience with Midas was bad and the only reason that they aren't getting one star is because the front desk manager actually refunded me. After getting my new tires from Costco, I called their Costco Auto Program that referred me to Midas to get a Wheel alignment done. I called Midas the same day, and did not mention I was referred by Costco. A gentleman at Midas told me the price and I told him I will be in the next day which they said they would be available at 11am. The next day, I called again, asking the same thing as a random customer, and again I was told the same price the day before so I take my car to the shop. Once I get to the shop the gentleman was very nice and this time i asked how much for a wheel alignment and I was told the same price as on the phone. Then I mentioned I was referred by Costco and have a 15% off coupon from Costco. The gentleman then said, "oh that price is the price for Costco members". That was the first red flag. He didn't check to see if I even had a Costco card or ask for the coupon. He also gave me a original price which did not match up to the "Costco" price after 15% off. I decided I didn't have time to argue, so I'll just pay their normal fee and have them do the work on my car. I was told it would take an hour and I went down the street to grab some food. After I returned to pick up my car, he handed me my receipt, which didn't have the alignment numbers, which was odd because this was not my first time getting an alignment and usually I get to see the numbers of different they are from before the alignment and after. The manager didn't mention anything charged me, handed me my keys and said everything is good to go. I trusted him and drove off. It only took me a minute to realize, that my car was still not aligned. I called Midas again and told the manager that my car doesn't feel aligned because it was still pulling to one side. The manager gets angry and says that's wrong, we use a computer to align it so everything should be good. I said, nope its not so he said to bring it back. I drive back and this time I stay to see everything done, and to my surprise and apparently theirs, my car was NOT aligned. Then they ask me did I do anything to the car after the alignment because it was aligned when I left. I told them I drove no more than 5 minutes so there's no way anything could have changed. Then after talking to the mechanic, they tell me that my car cannot be properly aligned due to some special tools they are missing. Funny how they didn't bother to mention this when I picked up my car. After wasting another 1.5 hrs there, finally I was offered a refund. Overall, I'd steer clear of this place. Few key points from this experience: 1. Manager lied about the price charged me normal price and didn't give me a Costco member discount, considering they are part of the Costco Auto program. I will be reporting this to Costco to have them investigate. 2. May not have done my alignment at all and just let my car sit there for 1 hour and claimed they did it. OR did do it, saw there was an issue but decided to not mention anything because they knew since my car was not aligned they would have to issue me a refund. 3. Wasted 2.5 hours of my time for a wheel alignment that should be done right the first time or at least notified me if they could not so I could go elsewhere. It was a horrible experience, and I will be notifying Midas and Costco about this shop and its business practices. If you need an alignment, plenty of other shops to go to. Do your research, call and get a quote first, and if the quote doesn't match up when you actually get there, that's a red flag to go somewhere else. read more
