GMC Complaints

The contact owns a 2009 GMC Envoy. The contact stated that while driving at an undisclosed speed, the service stabili-trak warning light illuminated. The contact stated that while depressing the accelerator pedal, the vehicle filed accelerate as intended. The contact stated that the failure occurred intermittently. The vehicle was taken to an independent mechanic, but the failure could not be duplicated. Additionally, the contact stated that the battery was drained. The contact stated that the failure had occurred several times previously. The contact stated the battery was charged. The vehicle was taken to an independent mechanic where it was diagnosed with a peracetic battery drain, the battery needed to be replaced. The vehicle was repaired. The failure reoccurred. The manufacturer was made aware of the failure but provided no assistance. The failure mileage was approximately 145,000.

While slowly driving, like when parking or trying to park vehicle in garage, it will randomly surge when almost at complete stop forcing vehicle to lunge forward requiring operator to apply quick additional firm braking. It almost feels like vehicle is creeping in 2nd gear and decides to downshift into 1st gear just before coming to a stop and engine applies slightly more throttle. I have almost hit garage wall and other vehicles in parking lots due to this issue. Again, it is intermittent but is alarming when happens. I have not had vehicle in for repairs yet but concerns dealer will not be able to duplicate. No warning lights on dash for this issue.

Blind spot warning system continues to illuminate when traveling on two lane roads with no objects in the blind spot(false positives). Especially the passenger side. I continue to be distracted while driving to check the mirror to see what is there, nothing. Then while traveling on multi-lane highways, both sides will sometimes not illuminate when there is a vehicle present in the blind spot. Both of these examples also happen more often after dusk or during dark/cloudy days. I have not taken into dealer yet for repairs but will soon. No system warning of malfunction on dash, just the false positive lights on side mirrors.

Overly sensitive automatic emergency braking/pedestrian warning. System would alert with lights and audible warning for no reason driving at ~55mph. While turning around in a Michigan left turn, system went off and brakes applied abruptly until I was at complete stop. No vehicles or persons were in front of me. There was a car following closely behind which almost hit me. Fast forward a few weeks later and now forward collision system inop light illuminated on dash and will not go off.

When the vehicle is in park and you try to turn it off with the start/stop button an on dash error code of ‘Shift to Park’ appears even though the vehicle is clearly in park. You are not able to turn the vehicle off. I am scheduled to take the vehicle in for service on 1/11/24. This currently is forcing me to restart the engine, put my car in reverse, shift back in drive, try re-parking and turning it off again, repeating the process until it eventually turns off. I do not know if my car is truly in gear or not. I’m afraid that it might cause a dangerous situation.

The contact owns a 2021 GMC Yukon. The contact stated while driving 25 MPH, upon accelerating from a light, the vehicle began to shake and decelerated and failed to accelerate and exceed 25 MPH. The vehicle accelerated, jerked, and stalled. The check engine warning light was illuminated. The vehicle was taken to the local dealer, where it was diagnosed that the fuel pump control module needed to be replaced. The mechanic informed the contact that the parts were on backorder. The vehicle was not repaired. The contact stated that the failure was related to NHTSA Campaign Number: 21V739000 (Fuel System, Gasoline). The manufacturer was notified of the failure and opened a case. The failure mileage was approximately 67,150.

When driving in a parking lot, due to the design of the cruise control set switch, it is very easy to unintentionally set the adaptive cruise control. Specifically, when maneuvering in a parking lot at low speeds (below 5mph) and allowing the wheel to return to center by spinning in your hands, the cruise control switch which is a dial/lever that sticks out beyond the surface of the wheel, catches on your hand and engages the cruise. This sets the cruise control target speed to a 15 MPH even if you are currently going slower than that. The vehicle then accelerates on its own at a fairly aggressive pace to get up to 15mph. You can of course hit the brakes and cancel the cruise control, but in a tight parking lot scenario this unintended acceleration could easily cause you to strike another vehicle, obstacle, or pedestrian. The cruise control on this vehicle is enabled by default on start up and the single action of hitting the set switch/dial engages the cruise and accelerates sharply even if you had not previously used cruise in that ignition cycle. This seems like a stupid design and dangerous, and would be very easy to fix with a software update to not let the cruise become enabled below 15mph. We did not have the dealer investigate because this appears to be the normal operation of the cruise control system. There were no unusual warning lamps. This has happened several times and also has happened to my wife while driving.
