While driving to work one morning an error message flashed engine reduced power, stability control loss. Truck struggled to accelerate. Has happened several times since November 2015 on city streets or highways can happen at any time. I had to replace entire system from throttle body to the pedal assembly have found out that this is common problem that GM knows about along with the cracks in the dash around air bag on passenger side and the instrument cluster and refuses to recall and fix cracks in air bag housing could pose a safety hazard along with loss of engine power from faulty wiring.

Dash has cracked from the passenger side airbag to the front of dash cap and along instrument cluster to the front of dash cap. This can easily cause a problem should the airbag go off. At this point I believe the center of the dash would shatter sending shrapnel to every direction inside the truck should the airbag go off or a collision. For me to replace this is going to cost $1000 this is GMC's responsibility for poor engineering and poor quality. They should fix this before someone gets seriously hurt or killed! I shouldn't have to spend $1000 on a $60,000 truck because the dash isn't supported properly to keep from falling apart. Besides, why spend $1000 on a new one when it's just going to crack again. Structural flaw!!

Dashboard surrounding airbag and instrument cluster is cracking and essentially disintegrating. If my airbag deploys or I'm involved in a collision these sharp plastic fragments will become a safety hazard. This truck has 38K miles and is in otherwise pristine condition with zero scratches on the interior parts aside from these dash cracks. The plastic is protected every three months at least with aerospace 303 and protected from sunlight when not in use. This is not a maintenance issue, it's a structural defect. Thousands of these vehicles are affected.

There is a crack on the dashboard right beside the passenger airbag on the inboard side. As the driver, I am worried that a shard of plastic could explosively tear through my skull, killing me, in the event of airbag deployment. GMC needs to fix this potentially dangerous problem before someone gets killed!!!!

The dash is cracked, there are two cracks where the air-bag is, which could possibly interfere with the deployment of the air-bag. This problem is widespread and involves several models and several years. I contacted the dealership and also General Motors and they refuse to do anything to fix it. Several people replaced their dashes at their expense only to have those crack also.

Dashboard has cracked in multiple places. In a crash or airbag inflation, loose shards of dashboard plastic may become hazardous flying debris or they may puncture and/or cut the airbag preventing proper airbag inflation and decreasing the airbag's effectiveness.

  • 50,423 miles
There are 4 cracks in the dash of the truck and 1 on the corner of the passenger side airbag my concern is if the passenger air bag deployed it could potentially send plastic flying projectiles and cause bodily injury or worse loss of vision. GM has not had a recall because they claim its not a safety concern but there must be a test performed in order to raise a safety concern or wait till someone gets hurt

This truck is four years old, has 30,000 miles, is garage kept (never parked in the sun) and the dash has cracked near the air bag area. I am concerned the deployment of the airbag could be affected by the cracked dash.
