Onstar connectivity module failed after dealer updates. The onstar module controls super cruise hands free driving. Module can fail during use causing accident. Vehicle did not display any warning on display screen. Vehicle is available for inspection. GMC dealer confirmed onstar module failure and is waiting on part delivery for replacement. Several searches in online forums confirm this is an issue for thousands of GMC vehicles.

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. It’s a 2023 and I don’t feel safe driving it with my kids.

My vehicle stalled while driving on a busy highway & I had no option but to pull over, which left me & my family in a very dangerous position. Had to remove my daughter's wheelchair onto a tow truck as the vehicle had no power to use the hoist for her powerchair. Again, on the side of a busy road! Towed the vehicle to a GM dealership, who stated there was catastrophic engine failure & the engine had to be replaced. Had no way to transport my daughter until I got a new engine since her hoist was stuck at the dealership. This was our original vehicle, until the sold me another one with the same defect (2024 Yukon for MORE money!). That vehicle was reported in Complaint 11657786.

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. There was a substantial possibility that other vehicles could not avoid me as I was exiting the travel lanes. There was also a substantial possibility that the vehicle would simply be in the travel lane stopped on a divided highway.

Driving in my newer GM Yukon Ultimate at 13k miles on the freeway. Vehicle with no warning shuts down while going 60mph in the middle lane. Was able to safely steer the car to the side of the road to avoid a collision. Vehicle lost all electrical contact. could not shift into neutral to tow. Turns out vehicle engine had to be replaced. GM approved a new engine replacement and are planning to return the vehicle back to put on the road. The vehicle is unsafe, at 5k miles, 6 months prior, the vehicle had to have the steering system replaced due to failure as well. Online research shows that others are having the same issue with failed engines on these GM vehicles and models.

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.
