I recently purchased my vehicle and after already transporting my family of 5, including my newborn child for several days, I noticed that my parking sensors were not working and I began receiving a message of my dash that parking assist, rear braking and auto park assist were unavailable. I reached out to GM around 4/4 informing them of the issue and they said they didn't have any recalls or retrofits for my vehicle and advised me to take it to a dealer's service deparment to be reviewed. After having an issue with Simpson GMC of Buena Park of failing to even review my issue for a week, I took it to Penske GMC of Cerritos on 4/17 and they determined that during manufacturing of the vehicle, someone failed to connect the module that controls my parking sensors. They had to remove the front fascia of my vehicle to connect the module for everything to work correctly. …
While driving at approximately 30 mph in moderate traffic on the interstate during a return leg of a 370-mile trip, my vehicle unexpectedly shifted into neutral and became unresponsive. The dashboard displayed the warning message: "condition not correct for shift," and despite repeated attempts to restart the engine, the vehicle would not engage. Although the electrical system remained active, I had no propulsion. Critically, the vehicle became immobilized in a **very dangerous curve on the interstate**, presenting an extreme safety risk to myself and others. The car could not be manually shifted into neutral for towing, prompting Illinois Department of Transportation (IDOT) to declare the location unsafe. I was stranded there for over three hours, after dark, in a vulnerable and exposed position. …
While driving in a gravel driveway, the window curtain airbags and the middle console airbags deployed, with no collision what so ever causing injury to the driver and should you have a child this could have been very damaging as the airbags came out in all the way back through the vehicle. This incident was inspected by police and fire as OnStar called them as it detected a collision, and without the vehicle being moved from the location the officer said there is nothing that should have caused the airbags to deploy, there is absolutely nothing here in this driveway that could have possible caused airbag deployment, The running boards go in and out, even when on the interstate constantly, and when backing up or going forward at times, and especially in a gravel driveway your automatic breaks will stop you abruptly, so fast that your seat belt will lock up on your and thrust you forward …
Following a catastrophic engine failure in my 2023 GMC Yukon XL Denali, I discovered that the vehicle could not be shifted into neutral once the engine failed. This prevented the vehicle from being moved out of traffic if it had stopped in an active lane. The inability to place the vehicle into neutral after a loss-of-power event creates a serious safety hazard, particularly on high-speed roadways. In the event of a failure occurring in traffic, occupants may be left stranded in a travel lane with no ability to push or reposition the vehicle, significantly increasing the risk of a rear-end or multi-vehicle collision. This condition occurred immediately following the engine failure and was not accompanied by any prior warning or instructions to allow safe vehicle repositioning. …
I was driving on a highway with my [redacted] son and 2 dogs when without any warning the vehicle just stopped and completely went dead. I was unable to turn on the hazards so I called 911, the police came within minutes and surrounded the vehicle to keep us from being crashed into. The brakes failed to work, the hazard lights would not work, the doors would not open other than the driver door. The police had to help remove my child and 2 dogs from the vehicle through the driver door. The vehicle could not be put into neutral so the police had to tow the vehicle from the middle of the highway. The result could have been deadly. The vehicle was completely dead with absolutely no function. After the police towed it to the police tow facility it was then towed to the GMC dealership I purchased the vehicle from. The dealership is Jim Curly GMC in Keyport NJ. …
At 9,900 miles my safety camera system failed which disabled the cruise control and all safety features that used the camera. Car was out of service for nearly two weeks and subsequently fixed by the dealer under warranty at no charge. At 11,300 miles I was driving on an interstate highway in the left lane at rush hour, without warning the car stopped accelerating the car shifted into neutral and totally lost power. It was a very dangerous situation with me in the left lane in heavy traffic. I am a skillful driver and thankfully I was able to make it off the travel lanes on the highway. The temperature was 18 degrees at the time and I had to wait outside for a tow truck. The engine seized without warning or noise and this presents a severe danger to the driver of the vehicle and other vehicles on the highway. …
Speed control became stuck and I had to hit my breaks to stop acceleration. Vehicle stopped shifting while driving down the road periodically. Warning collision lights and traction control lights randomly come on with nothing in front of vehicle. Yesterday vehicle would not start or even unlock. When I did get the vehicle to start by manually unlocking it and trying over and over it would not go forward or backward although the engine did rev up. All warning lights were on including traction control and check engine. It did randomly start moving but the "service steering column" light and check engine light are still on . The car periodically revs up while going down a hill when it needs to downshift instead. It has completely shut off driving down the road through town and stopped. I had to hurry and turn it back on as there were cars behind me. …
