GMC Complaints

The rear view camera is not sufficient for full time use. The camera is positioned too low and during times of dawn/night/dusk if a truck of similar size pulls up behind you, your camera is completely blinded by headlights. Leaving you unable to see anything in the rear view camera. This is a serious safety concern as you are unable to see if anyone is approaching your vehicle to cause you harm. The low camera placement also does not allow for an acceptable/comparable view as using the rear view mirror. The zoom does not pull out far enough to see multiple lanes of traffic and even during the daylight, if someone is approaching the vehicle to cause you harm, it would not be visible. The camera placement only allows you to view the front grill or hood of the vehicle behind you.

The contact owns a 2021 GMC Yukon. The contact stated that while driving at various speeds, the vehicle failed to accelerate as intended while the accelerator pedal was depressed. The messages "Reduce Acceleration - Drive with Care", "Service Traction Control", and "Service ESC" were displayed on the instrument panel.

The vehicle was repaired at the owner’s expense; however, the failure reoccurred. The vehicle was taken back to the same local dealer, where it was diagnosed as possibly needing a low-pressure fuel pump failure and codes that needed to be cleared. The vehicle was repaired; however, the failure reoccurred. The vehicle was taken back to the same local dealer, where it was diagnosed as needing a high fuel pressure pump reset. The vehicle was repaired; however, the failure persisted. The vehicle was taken to the same local dealer, where it remained for further investigation.

Vehicle keeps intermittently coming up with "Power Steering Reduced: Drive with Care," during this my steering is perfectly fine, however my A/C stops blowing cold air, the temperature gauge stops working and my engine fan is running constantly. This is obviously a well known issue since googling that warning and my vehicle it comes up with the issue and what the cause is. Which the cause is from the thermostat remaining open and allowing coolant to run through the system, even when the vehicle is not overheating. I just bought this vehicle used from my local dealership and am surprised that GM has not recognized this is an issue affecting numerous vehicle. This should at the very least be put as a warranty covered issue!

While engaged, Super Cruise failed to detect lines on road on a bend and launched the vehicle in the opposite lane without warning. This has occurred two separate times. First time was in late June 2025 on the PA Turnpike. Traveling at 70 mph. It was a left hand bend in the road where it failed to detect lines on road and thrust vehicle into the right hand lane. Happened so fast there was no time to react. In addition Lane Keep Assist was active as well. Also note lines were present on the left and right side of vehicle. Luckily no one was beside me. Second time was one a two lane road going 45 mph. Same scenario as first. Vehicle DIC stated it had lost road lines and threw me into the left lane without warning. Luckily no car was coming or it would have been a head on collision. Same message o display vehicle lost lines on road.

My truck is experiencing the Brake Controller failures as documented in GM Bulletin N232414840 - Customer Satisfaction Program Intermittent Loss of Trailer Brakes. This problem has occurred several times over the past year. I thought it was the wiring on my trailer - so I checked and found no problems (plus it works properly on other tow vehicles). Additionally, the problem resets and works properly after turning the truck off and back on (resets the system). It then works properly until it unexpectedly disconnects again. I thought the problem was unique to my vehicle until I got online and discovered that this is a known issue for others as well (2024 GM HD trucks). I contacted my GM dealer (and GM's customer satisfaction center as noted in the bulletin) and they informed me that my truck is not covered under this recall (not one of the covered VINs). I told them that I'm having this issue and they told me to report the problem to the NHTSA. Needless to say, GM has not included all the applicable vehicles in their recall (like mine) and I need the issue corrected before it causes a serious accident.

UNKNOWN: Transmission/Torque Converter etc. like driving over "rumble strip. shuddering (rumble strip feel, shake), when it happens (e.g., during light acceleration between 25–80 mph)

the digital gauge cluster suddenly black out and do not show any information such as speed, rpm, signal, etc at all. this is very serious issue for driver and passenger safety.

While driving on the and merging onto the highway, the check engine light and other alerts came on our 2021 GMC Yukon. There was a fluttering noise coming from the engine and the vehicle started to have decreased acceleration. We had to immediately exit the highway and park the vehicle. We then had to take our vehicle to our regular mechanic since GMC dealership was backed up and we needed the vehicle repaired. Our mechanic has identified the issue to be with the engine. The lifters in the engine broke which also damaged the cam shaft. This is a very costly repair. Our vehicle is four years old and out of warranty since we have 80k miles on our four year old Yukon. This problem with the GMC L84 5.3L V8 engines seems to be a common issue and other owners have posted their frustrations on various websites and there is currently no recall on this 5.3L engine. This is a safety issue and a recall should be issued like the one for the 6.2L engine. Why is there no recall for the 5.3L engine? A recall needs to be issued for the GMC L84 5.3L V8.
