GMC Reviews

Long story short (over 10 months of fighting - Calling nearly every day), we owned a 2017 suburban premier. My wife and two small children were driving to soccer practice when my wife hit a pot hole. This is a common occurrence that happens to most of us on a semi-regular basis. However, what is not common, when my wife hit the pot hole, a portion of the 7 total airbags deployed. Burning my wife's arm and scaring my children to death. Luckily the injuries were only minor. Now, we were instructed by our insurance agent (because the car is now "totaled" basically) to call GMC and they should have a program to assist with clear malfunctions like this. We were told that there have been numerous other cases where airbags have malfunctioned and manufacturers are normally open to assisting in these cases.

I recently purchased my first GM vehicle, a 2025 Buick Investa while living in St. Louis. Unfortunately, I've had continuous issues with the passenger side door speaker, which has been cutting in and out and producing a lot of static. When I took it to the dealership, they acknowledged it as a known issue and assured me they could fix it. However, just two weeks later, the problem returned, along with issues with the vent knob, which broke after I attempted to adjust it. I visited several dealerships, Houston TX only to be told at the last minute that they didn't have the necessary parts, despite having made appointments. This has been incredibly inconvenient. Today, I drove over an hour after leaving work early to get my car fixed, North 1 Houston TX only to find out that the dealership's internet was down for two hours and they hadn't notified any of the customers with appointments.

I bought a 2017 GMC 6.2 new, kept it serviced better than factory recommends, it had a lifter noise. Had to replace cam, all lifters, etc. Parts alone were over 2,000.00. Labor was as bad, it's a 4x4. I've owned GM pickups since the 70s and would not drive anything else, I worked at Chevrolet dealer in the 70s now I will never buy another one, if I ever buy another truck it will either be a Dodge Hemi, or a Toyota pickup. I never thought I would say that but they have designed a problem child.

I own a GMC 2022 Sierra Denali that has been sitting in the dealership parking lot for 5 months now. The engine light came on and it was diagnosed with a transmission issue that they can not seem to acquire the part to repair it. They have no idea of any kind of timeline for the part and are telling me that I could be waiting a year for the repair. Meanwhile, I have contacted corporate and they are not offering me any more information or hope for the repair. I have not been offered a loaner that I can use and am at the mercy of GMC. I will never, ever buy another GMC vehicle of any kind again. The company is the worst I have ever dealt with on any issue that I have ever had with a product. As long as they receive money from the government to keep the company running, they do not need to worry about making their customers whole or happy.

I currently own 4 GM vehicles and 10 over the years. Never again. Letter to GM. I am writing to formally express my deep dissatisfaction with my recent experience as a GMC customer. Over the years, I have been a loyal supporter of the brand, having owned no fewer than ten GMC vehicles. In total, I have owned over twenty different vehicles, including motorcycles, and I can confidently say that my recent experience with this Buick has been the worst I have ever encountered with any automotive company.

Purchased a new 2025 GMC Canyon. Day 4, engine light came on. Took it to local dealer (different from purchase dealership), and they told me that the entire engine may need to be rebuilt. This may take 4 - 6 weeks. That is roughly three times as long as I have had the vehicle. They did not have a "courtesy" car so I had to Uber it to Enterprise, rent a car on my dime, and wait. We will see how long this takes.
