What 2012 GMC Denali owners say
Most recent owner complaints, unedited.
The dash has cracked above the instrument panel and by the air bag. Unsure when it accorded. Noticed it was making a sound and in 2 weeks has gotten much worse
Crack in passenger side of dashboard....vehicle was statioary
My dash is cracking for no apparent reason. It's to a point now of needing replaced and has raised my safety concern for myself and passenger if I was to come involved in a crash by broken large plastic fragments.
When the vehicle is at 50 60 or any speed - the tachometer jumps and the car surges feels like it going to stop
Dash board has cracked around airbag. Concerned that if there was a collision that tye airbag would explode and entire dash would explode with it
