Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“Above 35mph I begin to get an extreme shake and vibration. It gets more and more pronounced as I drive. At 65mph is nearly unbearable, and shakes and vibrates violently. It gives me headaches, and I can feel it in my arms as I drive. I first noticed it about 100 miles after buying the truck. It now happens daily.”
NHTSA complaint #11325950, filed 2020-05, 60,000 miles“My air conditioning stopped working at only 51,800mi and just over 3 years old on my 2017 Gmc sierra 1500 denali. My mechanic said my AC condenser is leaking and needs to be replaced. He said it is a widely known issue but not a recall.”
NHTSA complaint #11399586, filed 2021-03, 51,800 miles“After being stopped like at a stoplight, then when it's time to accelerate, the truck has a hard jerk to it, and it doesn't want to down shift. Plus when riding down the road, the truck will lo just suddenly jerk so bad that it feels like someone ran into the back of the truck. This has been going on for a long time, and I have taken it to the dealership 4 times and they said they couldn't fix it. I even rode with them, and it did it. They still didn't want to fix it.”
