NHTSA complaint #11217302, filed 2019-06, 40,000 miles

“The dashboard in my 2011 Gmc Sierra Denali 1500 has multiple cracks in the dashboard, they have appeared significantly within in the last year and gotten much larger to the point where a hole has opened up due to a piece of the dashboard breaking loose and falling inside of the dash console. The cracks and loose debris have caused me concern because if the airbags were to deploy during a motor vehicle accident the occupants of the vehicle would be subjected to flying debris/ shrapnel from the dashboard. …”

NHTSA complaint #11277871, filed 2019-10, 112,276 miles

“The dash cracked near the passenger side airbag. The dealership said they know all about this and said it is safe to drive. Fearing plastic pieces flying in the event of an airbag deployment, I paid to have the dash replaced. Later, I drove into a pothole at a very low rate of speed. The second dash cracked in the same spot. The dealer says it is my fault and that there are no safety concerns. Gm is aware of this and is unwilling to pay for a new dash. They are jeopardizing the lives of my passengers so that they do not lose profits. …”

“On july 29, 2015, while driving at approximately 45 MPH, the vehicle suddenly downshifted itself into first gear causing the vehicle to slow down suddenly with no notice. I was able to get the vehicle off the road and into a gas station. After the fact the check engine light was illuminated. The vehicle was towed to the dealership. I was told the TCM (transmission control module) needed replacing and that there is a known issue with this year truck. This is a very dangerous situation to have your vehicle suddenly slow down while driving at speed. …”
