Example complaints

Other or unknown: “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

Transmission and drivetrain: “While driving my Gmc Sierra Denali the transmission shudders really bad. I have a 2017 with just 13,200 miles on it. I was pulling my bass boat and the shurdder was so bad my dash was shaking and the steering wheel was also .I have had the fluid changed at the dealership and it shifted fine and did not shudder until it reached around 1000 miles after fluid change and it is doing it worse now than before. I took it to the dealer close to me and they informed me today they were going to do nothing and they told me to take it back to the dealer I bought it from! This is unacceptable! …”

NHTSA complaint #11364221, filed 2020-10, 13,200 miles

Engine: “Noticed vivid and persistent engine vibration shortly after purchase - with no associated check engine code. Vibration happens at all engine and ambient temperatures (especially below 50 degrees fahrenheit), at all altitudes, regardless if in park, neutral, or drive. Vibration is so noticeable, you can watch the waves vibrate through a class of water when placed on the dashboard. Taken to two different dealerships and both have stated the vibration experienced is per normal design for 6.2l engine. Hard to believe GM would design a $65k+ vehicle that purposely vibrates/shakes. …”

Air bags: “The contact owned a 2017 GMC Sierra Denali. The contact stated that while driving at 65 MPH, he briefly fell asleep. As a result, the vehicle left the roadway and collided with the exit median, coming to a complete stop after careening into a side ditch. The air bags did not deploy, and the seat belt failed to properly retrain, resulting in head and neck injuries. No warning lights were illuminated. A police report was filed, and injuries were reported. …”
