Quality Buick GMC

I am writing once again to express my escalating frustration and disappointment regarding my 2022 GMC Sierra 2500HD Denali. Despite numerous service visits, the issues with this vehicle remain unresolved. As of today, my truck has been in the service department 32 times, all related to the diesel exhaust/emissions system. Most recently, I picked up the vehicle from Quality GMC on July 1, 2025, only to have the check engine light return just two days later, on July 3, indicating yet another emissions-related failure. This is completely unacceptable. I have been patient and cooperative throughout this ordeal. My previous complaint came when the truck was in for its 15th service visit. That number has now more than doubled. It is beyond clear that this vehicle has a serious and persistent manufacturing defect that GMC has failed to properly diagnose or repair. I have repeatedly asked GMC to step in—to take accountability and assist with a buyback or replacement. I have even expressed a willingness to purchase another vehicle if GMC would simply help me out of this ongoing nightmare. Yet, despite my efforts, I have received no meaningful support or resolution from either GMC corporate or the dealership. How many times must a customer return to the shop before GMC stands behind its product? This experience has completely shattered my trust in your brand. I have acted reasonably, given your service teams multiple opportunities, and documented every visit. I am now left with no option but to explore legal and regulatory remedies. These include: Filing a formal claim under the New Mexico Lemon Law Reporting this matter to the Better Business Bureau (BBB) Submitting a complaint to the National Highway Traffic Safety Administration (NHTSA) Publicly sharing my experience so others understand the risks of purchasing a GMC diesel truck I urge GMC to take immediate and meaningful action. I am requesting a formal response with a proposed resolution—whether that be a buyback, vehicle replacement, or financial settlement. Please treat this matter with the seriousness and urgency it deserves. Sincerely, Mike Martinez

Very shady dealership, at first our family had called to get a gasket replaced, quoted 2.9 hours, make it 4 just being fair because mechanics need to eat and take breaks too, ended up staying 9 hours, lady named Destiny told us the mechanic said the front brakes were shot and needed new pads and rotors, mind you the gasket was around 400 parts labor and tax, ended up paying an excruciatingly high price of $1400 for pads rotors and a measly gasket plus labor and tax, ridiculously high price for all of that, destiny never even gave us an estimate of the price for the pads and rotors, deceptive practices are very common here, workers always have a frown on their face and it gets even worse when you approach them, car was leaking oil and after the mechanic “repaired” our vehicle it was still left with the same problem we took it in for, ended up leaving extremely disappointed, basically they robbed us of $1400 and left with the same problem, maybe even worse, actually yes with low coolant AND low oil, after the circus was over they still drove it back and added another quart, mechanics are either high or have their experience from middle school, very unprofessional and deceptive dealership, would rate 0/5 if I could. If you need your Buick or GMC serviced, I beg of you, find another place or do it yourself and save yourself a lot of money, because these guys are hungry for it and will take every last penny.

I purchased my 2018 Buick Encore from Quality in 2017. I have been extremely pleased with the staff, service department and my vehicle since 2017. My June 19, 2025 scheduled maintenance visit was my very first disappointment. I scheduled my regular maintenance visit and shared that my front passenger door's lock was no longer working and the customer service rep told me they were too busy to check the lock. She said that I needed to schedule a Monday visit. Usually, the service person comes into the waiting area and share recommendations and findings. That did not happen on June 19, 2024. I waited over two hours for my vehicle and walked outside and saw that my vehicle was parked in the area where completed vehicles were parked. I went to the Service window and asked if my car was ready. The young lady got up and went to look for my paperwork. She told me a gentle would complete my paperwork when he completed the client's he was servicing. Eventually the gentleman came into the waiting area and told me that my paperwork was at the service window. I looked at my paperwork and asked where were my recommendations and she said if they weren't written on the paper they probably didn't have any. I asked where were my rewards discounts and she said she didn't know that I had any. I shared when I scheduled my appointment, I indicated that I wanted to use my reward points. Then I discovered that the oil change monitor had not been updated after the oil change. The service gentleman went outside to reset the monitor. This experience did not reflect my usual Quality Buick service experience. Not sure if there's been a change in Management or if inadequate training of new hires led to this experience. I just want my traditional Quality Buick experience to return.
