GMC Complaints

The contact owns a 2017 GMC Sierra 1500. The contact stated that while driving at various speeds, the vehicle jerked and stalled with the check engine warning light illuminated. The manufacturer was notified of the failure and informed the contact that there were no recalls on the VIN related to the failure. The contact was referred to the dealer for assistance. The vehicle was not diagnosed or repaired. The failure mileage was unknown.

Unwanted Radio Volume Ramp Up to Max: The radio volume turned up to the maximum while driving and could not be turned down with user controls including those both on the steering wheel and the volume knob on the dash. The situation lasted about 60 seconds before it began responding again. The vehicle has the optional Bose radio system which is EXTREMELY loud. This issue presents risks with damage to my small daughter's ears, as well a significant distraction from driving due to frantic attempts to decrease the volume while being overwhelmed by the noise level.

The rear window is leaking severely. It seem to be an ongoing issue with these trucks at the rear brake light spoiler. It’s a substantial amount of water and there is water damage and mold.

The rear window on this vehicle is leaking water and has been for some time. It has become quite bad and is causing an odor and discoloration in the carpet. I could not find the cause of the problem until recently with the plastic cracking more. The vehicle has 41,000 miles and the dealer stated that is out of warranty and all repairs would be a cost to me. I researched this and have found it is a common fault this this vehicle.

My 2021 Acadia digital dash goes out (completely black). I took it to the dealership on Friday August 25, as the issue was happening more frequently. I was told the software was not current. This was attributed to parking in a garage each night. Yesterday September 22 while driving, the dash again went out for a much longer timeframe (several miles). I called the dealership. Service was closing but was told by the receptionist that one of the sale people said to (1) park the car, (2) turn off the engine, (3) open the drivers door and leave open for 5 minutes to reset the system and everything should be fine. The black dash prevents the driver from seeing current MPH. I am uncertain if it also disengages adaptive cruise control and auto-braking. Is it acceptable for the digital dash to routinely go black while being operated? Is there a more sustainable resolution for the dash going out? Thank you!

On Sept 17, 20123 my SUV stalled while driving in heavy traffic causing a sudden and unexpected loss of power and putting me in jeopardy of a crash My vehicle was towed to the dealer as it would not start. The dealership replaced the Fuel Pump Power Control Module. There is a recall for this part on 2021 Yukon. My vehicle was not included in the recall. Further, this make /year SUV has 11 safety recalls . I contacted GMC and opened a case. No one has contacted me to discuss the issue. I called several times and have been provided little information other than “the Regional Service Rep” will contact me and that GMC sent an email to the dealership. I have been repeatedly told my vehicle is not part of the recall. Logic dictates otherwise. I do not believe the part failure was a coincidence. Rather, the recall should have included my SUV. Further, GMC should contact me to discuss this issue as a consumer with a safety concern. I cannot operate this vehicle with confidence knowing that some of the other recall items could cause a sudden loss of power. I do not have trust in GMC to accurately identify vehicles with issues. I want GMC to explain how any driver should feel safe to operate a vehicle on the roads under these facts- knowing a vehicle was not included in one of the recalls and could be left out of others. I also question why GMC makes a vehicle that cannot be put in neutral without the vehicle running. This creates a whole other safety issue if the vehicle stalls on a highway and needs to be pushed off the road. I had an issue with the tow because of this fact. In summary for required information: 1)Unknown if the part is available as the dealer removed it 2) I was in traffic and my vehicle stalled 3) The dealer confirmed the part needed to be replaced as the SUV would not start 4) See number 1 5) There were no warning lights or other. The SUV stalled. I know GMC wants to make a profit. It should not be at consumer’s safety and peace of mind..

The engine light has come on spuradically for the last 1.5 years and has been consistently on since May of 2023. This starting approx. 95,000 miles. During this time after starting the Yukon it is chuggy and missing, as I drive off it jerks and darts forward. Seems to be when I stop and start to go this happens, again engine light is always on...sometimes flashing. Starting 9/19/23 (106,000 miles) when slowing down to turn into a parking lot the engine revved high, no movement with the touch of the gas pedal and suddenly takes off with a jerk and a squeal of the tires. VERY SCARY. Since then I have experienced this DAILY, at least once a day. So far it is when I am going slow, either taking off and accelerating or slowing down. The engine and RPMS rev up and go high with no way of moving when touching the gas pedal then suddenly jerks and takes off with the tires squealing. I am also experiencing the transmission shifting VERY hard, mainly when slowing down. I am feeling very timid and scared to drive this vehicle...this is a seriously dangerous situation and can cause a serious accident or life! I believe this fits into the description of the GM Class Action Lawsuit filed over transmission problems. When I previously talked to the dealership they kept saying that there was no recall for the problems and to bring it in. I am not going to continue to get things fixed that do not fix this problem, as I have already. I know of a friend who has the same vehicle/year only a Tahoe and is experiencing the same problem and had work done at a dealership with no fix for their issue neither. Something has to happen with this problem from GM! The contact stated the issue has gotten worse pushing down the gas pedal rendering the vehicle immobile, then all of a sudden it jerks and shifts into gear jolting the vehicle forward.

The contact owns a 2012 GMC Acadia. The contact stated that while driving 70 MPH, the RPM would rise to 4,000 however, the vehicle failed to respond as intended. The check engine warning light was illuminated. The contact pulled over to the side of the road and inspected the vehicle and became aware of smoke coming from the engine compartment. The vehicle was towed to an independent mechanic where it was diagnosed that the engine block, camshaft, reverse gear, and transmission housing needed to be replaced. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was 158,000.
