Our Reviews

Jonathan was great! We met with him 2 times before making the purchase and both times he was very helpful and patient with us.

Speaker still broken

We returned to purchase our most recent vehicle, 3rd Chevrolet, due to the fact EVERYONE treated us fair, the staff was very respectful, and helpful during the entire process. Mr. J. Gotti helped us navigate a great deal and we now have a shiny new vehicle in our driveway. We will always recommend this location for new Chevrolet needs. Thank you very much.

Very good service

Great experience, good people A plus service Matthew went beyond expected to make the deal happen for me .

Jesse helped me alot and was a kind open spirit

The techs did not set the tire psi as written on the service doc. With a tire pressure device, the on-board monitor is inaccurate by 3- psi.

It was a little busy but great service

Took too much time in my vehicle. Now my vehicle has a ckech engine light,

Came in for an oil change and Jeramie took good care of me. Wasn’t there very long and I was back on the road. Thanks

Awesome. Everyone did an awesome job

Jonathan and Duc were great to work with for our Traverse and Silverado. Received wonderful customer service and both went above and beyond to take good care of us.

Found the truck we wanted and got help from Chevys employees to get a great deal and process the paperwork quick. No all day at dealership

Plenty of communication throughout the whole car buying process.

made an appointment started working on it before I left.. communication with me was great everyone asked if I was ok or needed help

EVERYTHING WAS WELL EXCEPT THE TECH DId NOT CHECK THE ENGINE LIGHT TO SEE WHAT WAS THE PROBLEM.

The sales is great and the financial director is awesome very attentive and very helpful

Helpful, good experience

courteous, efficient, knowledgeable and listens to needs and gets the job done. Always great to bring in vehicles for service needs over the years and treated like old friends. New staff, carrying on traditions. Thank you for all your help over the years.

Frustrating to say the least.....Appointment was made for 8am(1st Appointment of the day) I watched as 4 cars were serviced in the same bay prior to my vehicle being taking care of. 3 hours later.....35 of which were actually spent on my vehicle, the service advisor could not get me a straight answer on my inquiry regarding a tapping noise coming from the engine bay and then said the tech. Said it's common on this vehicle. Add this to a list of DO BETTERS!

Service rider could have been a bit more enthusiastic! First impressions is always a lasting one .

Jonathan and the finance team took great care of me. He listened to my expectations, met my demands and exceeded them.

Love the staff at Diamond! The person who maintained my car did a great job!! I believe her name was Yecini. All staff was wonderful

Very friendly and quick accurate service

Had a appointment for 9 for a oil chnage end up being there for 3 hours. Aslo the lady mechanic that was working on my & another car at the same time need a rise if yoi guys have gave her one!

It

I came in to have my car's air-conditioner checked out because it is not working the way that it use to. It does not get as cold as it use to and there is warm air in the car while the air-conditioner is on. I left the car at the service center. The repairman called me and said that the car was ready to be picked up. When I came to get the car the repairman told me that the air-conditioner was working good now. He said that it would get so cold that I would need a jacket to wear. He had me to sit in the car and turn the air-conditioner on. It did not get cold. I said -is that it. He assured me that it would get cold. It still does not get cold and it takes a bit longer for it to just get cool and there is still warm air circulating inside the car.

Their certified service department is all about customer satisfaction. Mr. Claudiu was amazing. He took the time to listen about my car issue and he made sure to keep me updated with the information provided by the service technician. Prices are very competitive and I was very satisfied with their overall performance. I highly recommend Diamond Chevrolet Dealership of San Bernardino. Thank you guys for your great customer service.

I had been working with Timothy Kubo for a few days on what my next vehicle would be. I explained my budget, and what type of vehicle I was looking for. He showed me the Equinox LT and I fell in love. He even went above and beyond and got me a color that I absolutely loved! He stayed in constant contact with me for 2 days on deals, special pricing and answered all of my questions quickly, clearly and with a smile. He took care of everything while I rested at home (being 9 months pregnant and all!) and when it was time, I went to the dealership to sign for my new car! Everything for the new car was prepped and ready to go. I was only in Finance for about 5-7 minutes. It was BY FAR my best car buying experience! Go on over to Diamond Chevrolet and ask for Tim Kubo!! You wont be disappointed! 100/10!

Jeramie Diaz explained everything to me and was very helpful answering my questions.

Good service

I made an appointment for an oil change for Thursday 06/19 at 7:00 am. The oil change took longer than is necessary. I didn’t Uber or go home because I thought it should take no longer than an 1 hour With an appointment. I got my truck back at 10:30 am. If I would have known it was going to take that long I would have ran some Errands or go elsewhere. I try to keep my business in the city of San Bernardino but things like this is making look elsewhere For a simple oil change

It was good Kyle duke was very help full

Great service writer!

Experience was amazing. My salesman Dylan Maraj was very friendly, knowledgeable, and hospitable. He took care of me, provided me with water and food during the entire process.

Brought my car in for an airbag recall and an oil change. When I came to pick up my car the paperwork was not right. The price I was quoted on the coupon was not present. They did indeed lower the price at my inconvenience. Upon driving off I found that my Sirius XM radio antenna was no longer connected. Went back to the dealership, was told it couldn't have been them. Truck was taken to the back to get looked at. 30 minutes later was told it wasn't them and I would need to come back for electrical to look at it. I drove in listening to XM and had no way to disconnect anything. They were working in that area and could have accidentally unplugged it. I also did not receive a copy of the inspection sheet. I won't be returning to this dealership.

Took almost an hour to check in. Got there at 650am to check in Left at 740am when the appointment was at 7am. Frustrating

My experience was very frustrating I would like to express my dissatisfaction with the service I received. I brought in my vehicle for a routine oil change and was told it would be completed the 3 hours or so. However, after calling multiple times to check the status, I received no clear update and my vehicle was not ready until the following day. This is completely unacceptable for such a simple service. Michael Alvarez was my service advisor. I was later told he had a family emergency and had to leave, which I understand can happen. However, what’s concerning is that no one else followed up with me or kept me informed about my vehicle. The lack of communication and accountability from your department was unprofessional. Needless to say, I will not be returning to have my vehicle serviced at your location.

Jonathon is amazing in Sales and Duke is great on the finance side!

I recently purchased a Chevrolet Suburban from Diamond Chevrolet and had such a pleasant experience! Elizabeth Ornelas was the salesperson who assisted me, and she made the entire process incredibly smooth. Her expertise and friendly manner made choosing the right vehicle easy, and her attention to detail ensured that all my questions were answered. The atmosphere at Diamond Chevrolet is very welcoming, which made my purchase experience enjoyable. I am thrilled with my new Suburban and couldn't be happier with the service provided by Elizabeth and the team!

Everything was great

The work on car, including recalls, was fine. The delays were long, especially for an Uber, one never came to pick me up.

Everyone was so friendly the experience was very pleasant it didn't take all day a few hours and I was out there in my new car so happy

You overcharged my husband for oil change. When I made the appointment I advised them I had the coupon online for $79’.95 and it included tire rotation. You guys charged me an extra $10 for it plus extra fees to dump oil. Total was over $106. I feel you took advantage of my elderly husband and for that I will no longer take my Camaro nor my Silverado there. I go out of my way to come to you as we live in north Fontana but for that price and that experience I will definitely be taking my services somewhere else And I will also share my experience with friends, family and social media!

I brought my vehicle in on May 19, 2025, due to a manufacturer recall. While i understood that repairs could take time, I expected at least basic communication about the status of my car. Unfortunately, that never happened. Between May and July, I tried calling no one answered, left voicemails and call was never returned. I even visited the service department, to be met with vague answers. I was even given a number to receive text updates - that didn't work because no one replied back. To make matters worse, we were told after the fact that the rental contract had expired and needed updated signatures. No one had called to inform us, and we were expected to just know we only found out because we went to the shop to ask for an update. I refused to return or sign anything until we received some sort of update. It wasn't until two months later, that I finally got my vehicle back. When I shared my frustration with the service rep, he apologized and said the original person who handled our service was let go back in early June. While that may explain part of the delay, it doesn't excuse the complete lack of follow-up from anyone else on staff. All we wanted was to be informed: what was wrong with the vehicle, whether it was covered, and how long it would take. This experience was beyond frustrating, and due to the poor communication and lack of accountability, I will not be brining any of my vehicles back for service here again.

Jeremy is doing a great job.

The salesman Omar Martinez was very patient & helpful. He made the experience very easy going. Also the finance person, Duke, his customer service was great. He explained to detail the contract and made me feel at ease.

Smooth service visit. 1 hour. Happy pleasant people. THANKS

Sales dept quoted 3 hours. For service. We had an appt. Dropped it off. Good thinner didnt wait. It was an oil change and a recall repair. 5 hours later and we can’t get anyone on the phone. The automated answer service is designed to make you give up. It’s a joke.

I took my 2025 Blazer EV to service for the first 7500 mile service. One part of the service was to connect the code reader to the port located to the left of the steering wheel, near the left foot area. When I received my vehicle after the service was completed and I was half way home, I felt something bumping against my left leg. Upon arrival at home, I noticed the diagnostic port was not put back as found when Im arrived. It was just left dangling. There was no noticeable affect in driving or vehicle performance, and I was able to put it back in place. This made me wonder, if this was not put back properly, what else was not correctly done, put back in place, or service not performed that should have. There are several Chevrolet Dealers within a 20 mile radius of my residence, two closer than Diamond Chevrolet of San Bernardino. With this lack of effort/attention to detail experience at Diamond Chevrolet of San Bernardino, I will take my vehicle to a different dealership to have service done. This is unfortunate due to an Exceptional Sales and Financing staff; however, purchase and financing is done. Service, did not meet same level of performance. Thank you

very good customer service

I don’t understand why I make an appointment and still took 1.5 hours to do plus I get in car and it’s wires hanging down from odb2 port Wich turns out to be a gps tracker. I just pulled it right out and put it in glovebox

Service was quick and friendly.

I always have a great experience with the service department. They are thorough in identifying any mechanical issues with my vehicle, even when I’ve brought it in for unrelated repairs. One area for improvement would be in the video walk-around process. When the service advisor completes the video for damage identification, I think they should review it with the customer and send a copy via email before the customer leaves. This would ensure clarity and provide the customer with a record for future reference.

I can’t say enough great things about my experience working with Joe Gotti! From the very first conversation, Joe went above and beyond to make sure I felt confident, informed, and excited about purchasing my new 2025 Chevy Suburban. Joe’s knowledge of the vehicle was unmatched—he answered every single question in detail and took the time to walk me through all the features, without ever making me feel rushed or pressured. He truly listened to what I needed for my family and made sure we found the perfect fit. What stood out the most was his dedication. Joe worked tirelessly behind the scenes to get me the best possible deal, made the paperwork process smooth and stress-free, and even followed up after the sale to make sure everything was perfect. It’s rare these days to find someone who genuinely cares about their customers the way Joe does. If you’re looking for a trustworthy, hardworking, and friendly salesman who treats you like family, Joe Gotti is the one to see! I couldn’t be happier with my new Suburban and the top-notch service I received.

I am happy that the dealership will work on older Corvettes. They helped me with a broken part but I was a little surprised at the costs. To replace the glove box handle which I had personally ordered the labor was 450$ That seemed excessive. The staff are nice and helpful and scheduling is easy.

Advisor claudio was

The people at Diamond Chevrolet were nice, friendly, and helpful. I dont feel like Im being preyed like the other car dealers.

Service was somewhat expidated. Service employee was cordial and friendly.

No pressure to buy. 100% satisfied

Good service

Work was done well. Slow getting waited on upon arrival. Oil change and tire rotation took 2.5+ hours after being told it would take 1 to 1.5 hours. No report received regarding 28 point inspection

I waited 25 minutes for someone to attend me at the service department. I was not in line waiting. I was next to be attended. The service members were too busy bullshiting with a female there. I was attended after Claudio helped me and asked if I was being helped. It look like he was checking with a mechanic. Claudio also fixed an error with the vin number taken incorrectly. I asked to speak to the service manager but apparently they didn't have one. I will not be going to this dealership for service and recommend service to be looked at by the GM.

Explain to them my problem what I wanted to have done exactly what I told them to do. Happy with results.

After hearing about a previous experience. The team here along with Jonathan was very careful to explain everything in detail to me and my daughter. We were given a tour to know all of the services that are available at Diamond Chevrolet now that we have purchased our new vehicle. Jonathan worked very hard to get me my dream vehicle, but alas we settled on the vehicle that was within my budget. They assured me that my GM buy back would coincide well with first payments of the new car without overlap. I left feeling less overwhelmed by everything, and thanked them for honoring my family general motors discount.

Good

I was very impressed by salesman Nael. He was patient and extremely helpful throughout.

The first car I took in they took the computers word for it on the code and wanted to charge me 5000.00 to replace both catalytic converters and O2 sensors but that wasn't the problem.They didn't verify first but after that I had no problem. The second car was there for 2 weeks because of employees turn around but once that was resolved I was very happy with the customer service and the outcome so I will bring both vehicles back again and just hope the turn around to get them back gets better

They are very friendly helpful and fast on doing all the paperwork I will definitely go back in a few years to get my 2500

Derrick is great at helping you understand all about the finance process. Tim was also great, along with the young man from Lebanon.

Was fast easy, with a smile

It was great. Everything went smoothly, and we found what we were looking for.

I took my camaro in on a wed, Max said it would be diagnosed Friday or Monday the latest, I called Friday and NO ONE was available to speak to, left messages and no response, the receptionist said the WARRANTY company was who they were waiting for, they had to GO IN and see the car, I called the warranty and they had NO SUCH INFORMATION! Monday I called and Max was out, I had to have my daughter go in and see whats going on so I can get a rental from the warranty co, the manager was unavailable and she was ignored for 1/2 hour while waiting, finally some spoke to her and said , itll be looked at tues or wed now, so I called and finally spoke to max and said, 'hey SINCE YOU HAVE THE CAR, HAVE THEM DO THE ANDROID AUTO IT HAS NOT WORKED SINCE I BOUGHT THE CAR 9 MONTHS AGO," he said ok, the car is in the bay , ill call them and tell them to do it. i get a text the car will be ready on Monday 10 days later, so I pick the car up and THE RECEPTIONIST WANTS TO CHARGE 700PLUS, I SAID NOOO I HAVE THE DED FOR THE WARRANTY AND SHE SAYS , OH YEAH I DIDNT SEE IT.... I GET IN MY CAR AND THE ANDROID AUTO IS NOOOTT DONE, ITS ALMOST 2 WEEKS NOW THEY AHD THE CAR. I WILL NEVER GO BACK THERE AGAIN!!

Very well really liked the promotion.

My vehicle was there for over a month and it wasn’t fixed properly. Vehicle wasn’t diagnosed properly. Seem like they were just charging parts and hoping it would be fixed. Communication between service advisor and my warranty weren’t rhe same. Spoke to service director and he said he would personally take charge of my vehicle and call me personally. He never did. I tried calling him for weeks and nothing. I will never take my vehicle there again. Gonna go buy a ford.

I was very satisfied with the customer service Maxwell is a person that I always go to very nice ready to to solve all your problems that you need to fix in your truck thank you Maxwell

This is the fourth Chevrolet we have purchased from Diamond Chevrolet in San Bernardino, and all purchases have been completed with the assistance and guidance of J. Gotti. Mr. Gotti is great to work with. He listened to our needs, provides us with options, and allows us to make the final choice which works best for us. He is a very easy, no pressure team member to work with. This is why we always seek him out for our new vehicle needs.

It was a very good experience very professional and the went out of their way to get me the best deal possible

There’s nice people that work there. I like it that I get to see the technician work on my car. I see how clean he is how neat he is and I like that very much.

Joseph Gotti helped me get into the car that I wanted. My experience here was great!

“I’ve been dealing with Diamond Chevrolet for the past few years, and honestly, the experience has been exhausting. The same issues keep coming back even after being ‘fixed’ under warranty multiple times — especially with the motor mount. It’s frustrating when a dealership doesn’t take long-term accountability for the quality of their repairs or the parts they use. As a customer, I expect consistency, transparency, and better communication. I hope management seriously reviews how service follow-ups are handled and holds their technicians accountable, because loyal customers shouldn’t have to keep paying for the same repairs year after year.”

the best!!!

Great dealership & sales man

Quick service.

Very fast service, in and out..

Excellent service. Completed on time as promised

Diamond Chevrolet has been my go to dealer for oil changes. My service appointment this week felt like I was at a new department. I really missed the old service team, they were awesome. I had a 1230pm appointment and left at 330pm. It felt like everyone was new and had no training. I dont fault the service writer as he said he was new, I fault the service manager, the new guy had no support and had to run around like a chicken with head cut off. My truck sat ready out front for 45 min just to get paperwork to the cashier. After the service was done, the truck was pulled back to the back lot only to sit there rather than being pulled up front to empty pick up area. I had to ask the employee to please bring the truck up. I witnessed 3 other customers ahead of me that were very upset about their service, communication, and wait time. Im going to try this dealer one more time with hopes, things get back to how service was before.

Jeramie is excellent. I brought our Colorado in because the air conditioning was working however there was no heat. Jeramie had the truck fixed with no problem every thing is A ok. And not only that he has a bounce in his step when he walks Jeramie that is.

My oil light came on and I was close to Diamond to help me with an oil change. Everyone was helpful and I was able to take care of my Traverse.

Jeremy was perfect, 85000 mile service, checked for recalls etc. What is rare today Jeremy listened. I thank all for a great job done.

everything was ready to go for me when I arrived

Amaz

Great service

Fast service

Poor communication with service department. Took in my vehicle for recall was there for 3 days. They won’t return my calls. I had to call to find out what was taking so long.

Went to get an oil change and tire rotation. Unfortunately the dealership took almost two hours for that. Even though I had an appt at 9:30AM. On top of that after I asked for the multipoint inspection sheet and the clerk said she didn’t have it. Then she tells me they were unable to do the tire rotation. I asked her why was I charged for it and then why wasn’t it done? She said the couldn’t find the tire lugnut key. I asked why they didn’t call me or look in the glove compartment… she said she didn’t know. I went and got the service advisor to let him know what happened and how this is unacceptable. He told me they would do it right now. After 20 minutes no call saying my car was done I just came back to the service spot to see my car there. I picked it up and drove to the dealership. I think my car is leaking oil now because my car is now having oil drop from the bottom. Will be taking my car back to see if they did something wrong. It’s a 2023 traverse with 20k miles… it shouldn’t have a leak.

Joseph gotti help us to get in a new truck

Took care of the issue fast!

We had a great experience.Narcico was able to work out all our needs to fit our budget.

Knew exactly what I was looking for, the team provided outstanding customer service.

I recently purchased a vehicle from Diamond Chevrolet in San Bernardino, and I had an excellent experience thanks to my salesperson, Timothy Kubo. Timothy did an outstanding job walking me through the numbers and explaining the reality of the situation with complete honesty and clarity. He was patient, polite, and genuinely kind throughout the entire process, which made everything so much easier and stress-free. His manager was also very friendly and took the time to personally go over the final numbers with me, ensuring I understood every detail. Their professionalism and transparency made this one of the smoothest car-buying experiences I’ve ever had. I truly appreciate the exceptional customer service from both Timothy and his manager. I highly recommend them and Diamond Chevrolet to anyone looking for a straightforward and honest car-buying experience!

Great service.

Friendly service and attentive. Made sure we got the vehicle we wanted.

My oil change was completed but I had an appointment and I was told that it would be about an hour to an hour and a half but it took two and a half hours.

Horrible experience Terrible service

I had a stellar experience buying my 2026 Chevrolet Equinox at Diamond Chevrolet. Elizabeth and jonathan was a dream to work with; they were knowledgeable, enthusiastic, and truly made buying a new car seem less daunting. Not once did I feel pressured, which is a breath of fresh air in car sales. I'm thrilled with my purchase and must commend the team for their professionalism. Anyone in San Bernardino looking for a new vehicle should definitely check them out; their service is exceptiona. The best thing was their finance department, im not lying to say that they had all the paperwork ready and I was out within 20min. I've had baugh and finance about 8 cars and I have to say this was the best experience hands down and all.tjanks to Jonathan and Elizabeth and the finance guy wich I dont know his name. Thanks you Jonathan and Elizabeth I mean it.

Great service and very helpful

Even though it was late Saturday afternoon, Luis found a way to get my truck taken care of.

Carla did a great job taking care of me there day was busy and they were short handed. She was great thank you

Wonderful customer service as always. Great experience

Joseph are salesman got us the deal we wanted and we left with our dream truck.

None of my gauges were reset like my oil filter life, oil, air filter… etc…tires weren’t rotated. I chose the $79 oil change online when I made my appt and I got charged almost $300.

They never wash my car and the person who attended me wasn’t to polite

Joe was amazing ! Excellent help. Don’t think we would of purchased if it wasn’t for him!

Fast and efficient

Slow service 🤦‍♂️

Amazing people very helpful

Your service manager is a scam artist I brought my tire based on a factory defect and he told me he did tens of thousands of tires no way it's a factory defect and it's one in a hundred million can be a factory defect and end up patching the tire and charged me $30 just like he cheated last time when I did an oil change they told my $99 and when done charged me $20 more I'm done with dealership it's nothing but crooks management

Great

Great customer service Quality service Great communication

The guy that helped me was very rude, and condescending every time I go in. Not very helpful at all. I've been a loyal customer for over a decade I bought several cars from this dealership. I know Nate its gone however I'm use to dealing with him and his great customer service. I've never said anything due to retaliation towards my vehicle. I try to be polite but it can only go so far dealing with someone who does not have any customer service. I paid for my maintenance when I purchased my truck and I have had several times where I'm given a bill. My side mirror was also broken by a technician and I've been given a difficult time with replacing it. I was asked to leave my truck over night for that mirror replacement which is outrageous. I use my truck for work I just can't imagen it taking that long. Which brings me to feeling distrust with crest.
