Diamond Chevrolet Buick GMC Cadillac

I am a very disappointed Diamond auto group service customer, I wouldn’t recommend them for service work to anyone. I purchased a 2021 GMC Acadia Denali from an Arkansas Chevy/GMC dealer and had it s customer, I wouldn’t recommend them for service work to anyone. I purchased a 2021 GMC Acadia Denali from an Arkansas Chevy/GMC dealer and had it shipped to Massachusetts where I live. The car has 45k miles on it in very nice condition and no NE winters. Upon receiving the car the backup/surround vision camera was working intermittently, maybe 50% of the time. Looking the up problem there is a recall for this exact problem. I have purchased a number of cars this way and accept that risk. I made an appointment to have the car looked at to see if it would be covered by the recall. Providing the VIN I was told the recall has already been performed. I still wanted to get the camera repaired so I made the appointment to have the problem diagnosed. The day before the car was to be taken to the dealer I was called to cancel because the service advisor was not going to be available. I misunderstand and thought that the person performing the work was not available, so the appointment was rescheduled. The service advisor is the person that checks the vehicle in, why did my appointment get cancel for that reason? I was quoted $199 to diagnose the problem, (the symptoms are exactly the same as the manufacture recall) so not something totally unique to my car’s problem. The car was in the diamond shop for a couple of days and I was informed that the rear camera was the problem and needed to be replaced (quote $521). The repair was approved and the service performed. I picked up the car and the problem was still the same, replacing the rear camera did not resolve the problem. I left the car again for about another 10 days and was called to inform me that they wanted another $600 to continue the diagnostics of the camera system. I declined and picked up the car. I then looked up the parts that were to be replaced as part of the recall repair (GM 86775887 and 86775888). Thinking that those would be a dealer only part and difficult to acquire. To my surprise they are easily available from a number of online vendors, seems that maybe this is not such a unique problem. Next I purchased the two parts from RockAuto and with a few hours of my time fixed the problem for $92.32 (tax and shipping included) by replacing the two cables that were replaced as part of the recall. Seems GM still has quality issues on these cables so replacing them for a 2nd time resolved the problem. I was charged $199 for diags, $521 for a camera that did not need to be replaced, and $17.61 in shop fees and I still had the same problem I brought the car in for and I fixed it myself for less than $93. I am not a mechanic (retired IT) the dealership should have been able to better diagnose this reoccurring problem with this make and model. More

Great customer care and response. Aime Barnes especially was a delight to talk to because she took her time to talk to me and explain everything. Aime Barnes especially was a delight to talk to because she took her time to talk to me and explain everything. More

Bought a brand new 2025 trailblazer from this dealership. I had it about a month and it started leaking transmission fluid. I brought it to the service department, where the service advisor told me they coul I had it about a month and it started leaking transmission fluid. I brought it to the service department, where the service advisor told me they couldnt check it that day and said it was safe to drive. I returned the next day and the service advisor continued to give me a hard time about getting a loaner. I asked to talk to a manager and then the service advisor finally agreed to find me a loaner and keep my car for diagnosis and repair. It was in the shop for 14 days, they had supposedly fixed the problem but the car is still not driving right. The worst experience with a service department I have ever had. What happened to the "lemon law". I do not recommend this dealership to anyone. Very poor. More
