The lighting on the entire interior infotainment area will randomly go bright and dim all by itself. I was almost in an accident on the interstate due to this. It was blinding and distracting to have the lighting dim and then go bright. It has been randomly doing this for about a month. I called GMC and they said they had no record of this happening on other vehicles, however when I searched for the issue with my vehicle, I realized other GMC owners have experienced the same issue. I was able to get a video of it happening one morning while waiting in my driveway to drop my kids off at the bus stop. I was in the parked position. There are no warning or messages when the lighting malfunctions, so I am not at all prepared when the car turns the lighting to MAX brightness. It poses a risk when driving by blinding the driver, causing the driver to loose focus while driving trying to adjust the lighting back to dim. It is an unnecessary distraction. The dealership couldn't confirm any malfunctions in my car. As previously stated, I have a video of the malfunction, but I am not able to upload it. I am willing to send via email.
The contact owns a 2021 GMC Yukon. The contact stated that upon the start of the vehicle, the vehicle independently reversed without warning upon touching the gear shifter. The vehicle first reversed into a cement barrier and then lunged forward into an intersection while she repeatedly depressed her brake pedal to no avail. The contact managed to call 911 and while speaking with an operator, she was able to regain control of the vehicle. The contact crashed into a parked vehicle as well as a barrier during the failure. Once the contact regained control of the vehicle, she pulled into a gas station where she was met by police. A police report was filed. The contact suffered mental anguish as a result of the failure. Due to the failure, the vehicle was towed to a dealer where they were unable to duplicate or diagnose the failure. The vehicle was then towed to an independent body shop where it remained in their possession. The manufacturer had yet to be notified of the failure. The vehicle had yet to be repaired. The failure mileage was approximately 20,000. The VIN was not available.
The vehicle had a sudden loss power shortly after i started the vehicle. When I pressed down the gas pedal, the vehicle turned off. It was only a 20 mph zoned residential neighborhood so I was able to safely coast to the side of the road. I dont think i could have safely gotten to the side of the road if it had been on any type of a multi lane road. There was no warning, no lights, no sounds that there was a problem. I had the truck towed to the local dealership as i was 120 miles from home. The mechanic at dealership said it was a faulty -??fuel pump power control module-?? and that they are failing a lot. Last I heard that the part was on nationwide back order. There was a recall for this very same problem over a year ago but my vehicle is not part of the recall. Yet the problems are still occurring with many similar vehicles (Tahoe / Yukon)
I own a 2021 GMC Yukon Denali that had TOTAL BRAKE FALIURE last Tuesday. I had it towed to a local GMC dealer and are repairing it under warranty. I was lucky to be on a back road when my brakes went out. I had no warning lights come on prior to hitting the brake pedal and was able to coast to a stop on the shoulder When I applied the brakes, the pedal went to the floor and did nothing. You can't stop the car with the parking brake because it is electric. My concern is what if I was on a busy road when this happened or what if this happens to a family in traffic they could be seriously hurt or worse yet killed. I do have good photos of my instrument panel with all of the warning lights coming on after I tried to stop. In good conscience feel that I have to at least try and report this to GM, the state and anyone else that will listen. If nothing comes of this at least I tried and just hope no one gets hurt if this happens again. My wife refuses to ride in that vehicle until I have solid answers. The dealer said they will have my car repaired this week and are replacing the master cylinder and ECS This is fine but why did it happen and how can I be sure it won't happen again? I believe in GM and have a 2023 Yukon Denali on order. I would hope that after 3 years of this model they have most of the little quirks worked out. A rep from GM did contact me and at first was talking about buying my car back but changed that today. My case number is 9-8497380349. The problem is I have no idea when my new car is coming in our should I just cancel it and find something else. In my opinion this is a very serious problem.

Travelling down the highway 69 mph with my wife and three small children when the dash flashed multiple error codes, engine speed limited to 62 mph, and brakes essentially went out. Was able to get safely stopped. Contacted dealership and they advised shutting it off for 20 min and it would "reset". it did not reset and we refused to drive it in such unsafe circumstances without adequate brake function etc. GMC roadside assistance came and towed it away. Could have resulted in much worse outcomes and we are thankful no one was injured. Very nervous to drive it again after we get it back, not knowing if it will malfunction again.
Driving approx. 62 mph on a highway, went to slow down and unable to brake, upon pushing down on the break there was resistance, after pumping the breaks multiple times I was eventually able to slow down with a lot of force. Messages on dashboard read "brake system failure" "62 max speed ESC, service ESC, service trailer break system, and forward collision system unavailable." ABS, ESC and check engine light all illuminated on dash screen.
We were coming back from a trip with my children and this vehicle was barely 2 weeks old with 0 miles and we were on a highway when all the emergency lights on the dash went off. It was flagging the electrical system, the engine, the brakes. Honestly all the lights possible went off. The vehicle was lagging and it felt force when we pushed on the gas. Our hands were gripping the steering wheel to keep it in lane till we could get off.
