The back hatch would not open while the car was on and in park. Upon reaching in without being in the car, we turned it off, and it engaged reverse on its own, causing it to reverse immediately almost causing terminal harm to myself and my family. It careened into the woods with us unable to stop it due to the immediate speed. No one was in the vehicle, it was solely self propelled. We have a video of the path it took and the damage it caused. When the car wrecked, even when turned off, the lights and windshields wipers engaged by themselves.
We just purchased this vehicle from winegardner GMC in prince frederick, MD. On [xxx} on our drive home from the dealership, we kept hearing a terrible screeching/ clucking noise coming from the rear when we were braking or applying any pressure to the brake pedal. We instantly contacted the dealership and they had us bring the vehicle back the next morning for them to look at and to make the repairs but unfortunate for us. They do not have the parts in stock, so we have to take it back Tuesday, October 8 , 2024 at 8am and leave it for the day. Hoping it is repaired correctly with the new parts “both rear calipers” as I left the dealership, I was approximately 10 miles away and out of no where my dash displayed “service, trailer, brakes”, constantly along with a loud dinging noise for the rest of the drive home. I contacted the dealership and spoke with the service manager and informed him of the situation. He told me it has been an ongoing issue with gm for years and it’s electrical and because we purchased a used vehicle. It’s not covered to be repaired. We would have to pay out-of-pocket for it to be fixed. This is very upsetting because we just spent $40,000 on a used low mileage Yukon denali for our family to travel in, but it’s unsafe, because it affects the traction control, and abs brake system. I would also like to note that I did not have a trailer hooked to the vehicle, so I do not understand how that service indicator would appear unless it was cleared by the dealership during maryland state inspection. We have asked them several times for a copy of the maryland state inspection they performed, and we are getting the runaround. As the purchaser of a vehicle, it is all right to have that document, showing what past and what failed maryland inspection before being resold to us.

May 31st 2022-while driving on the highway, I lost control of my power steering. Luckily my husband was with me to drive it back home. June 1st 2022-took it to a service center and was told it needed a part to fix the problem. We ordered the part, which would not be delivered until may 6th 2022. June 4th 2022- went to drive, made it a couple blocks down the road when the abs, electronic stability control, & the engine light came on. So I turned around to take it back home, only now my power steering was completely out, my car would not shift out of first gear. After arriving home, I attempted to put it in park but was unable to. My motor shut off but would not allow me to place it in park or turn the electric power off. The only option I had was to disconnect the battery. I let it sit for a few hours, reconnected the battery, now my car will not start at all. I am now unable to take my car to the dealership due to power failure note: June 2nd & 3rd, my vehicle was not driven I did contact my local dealer to check if there were any open recalls, was told no.
I was involved in a traffic collision. A large vehicle turned left in front of me and I t boned that vehicle. We were traveling about 30-35 mph at the moment of impact. My vehicle sustained major damage ($20,000+) to repair according to the body shop. My wife, daughter and myself sustained injuries. My wife and I have significant injuries. I truly believe, based on vehicle damages, and injuries that our airbags should’ve deployed. I believe it has a fault sensor that should be inspected.
Keeps showing a service trailer brake system, it does it once in a while but when it does it keeps showing the message after pressing dismiss, I was researching online and apparently there is a lot of people dealing with this same issue and looks like it is a defect from factory.
Side rear brake lights work intermittently, often cutting out and losing all power while driving.
