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. The contact was transported to an area hospital by EMT and treated for various lacerations to his head and arms and an unstable fracture of the C7 in his lower neck, later requiring surgery. The vehicle was towed to a tow yard and deemed a total loss by the contact's insurance provider due to a bent chassis. The manufacturer was notified of the failure, and they inspected the vehicle, concluding that the impact was not sufficient to trigger air bag deployment, estimating that the vehicle was traveling between 1 and 4 MPH and that the air bags were functioning properly. The VIN was not available. The failure mileage was 32,000.

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! I understand from all I have been reading about this problem gm still IS building and selling trucks with the 8 speed trans in them and still having problems. Really? I guess I will keep driving mine and I hope the transmission just comes apart then they will give me another transmission doing the same thing! just great gm!

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.

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. *tr

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. escalated through gm corporate (sr# 8-3108393xxx), to which they confirmed truck IS running as designed. since the engine was not throwing a code, no further investment/resolution was needed on their end. their solution to me...sell the truck if not happy. of course they did not say that, but that's the way I interpreted their response to mean. buyer beware.
