What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
When slowing down the vehicle surges forward even when brake is being applied. It does not appear to be related to engine surge as it does with sudden gear change as if the vehicle is speeding up from a stand still.
Service stabilitrac system indication comes on, with check engine light, and engine power reduced. Happens randomly, cannot find a "common cause" spent lots of money on pcm, bcm, memory seat module, battery cables, battery, brake light switch, etc. Etc. Dangerous condition when vehicle drops into power reduction mode.
Safety issue. Dash is cracking near airbag. This could possibly cause premature deployment of airbag or shrapnel from dash causing harm during deployment. Dash is also cracking over steering wheel area.
Air bag service light is on the truck will surge with no warning cause the instrument to black out and would cause the truck to stop check engine light is on with no key and control on the steering not functional
Dash cracked right above passenger airbag deployment area. No discoloration in the area or any warning. One day fine, the next day a crack appeared. Truck was parked most of the day and my work commute is 6 miles round trip. I don't off road and I have normal sized tires so no vibration occurred.
Numerous calls with chevy have failed to resolve the problem and chevy refuses to guarantee, in writing, that the airbag will still discharge properly in an accident and remain seated properly and that the radio will not dislodge from the dash. This vehicle is well maintained and has approximately 51k miles on it.
2011 chevrolet avalanche ltz. Dashboard is cracking above the instrument cluster, almost directly above the speedo. Finding a lot of forums on this problem with gm trucks and suv's.
I was driving my truck at about 45 mph when the traction control light came on the dash and my truck suddenly went from 45mph to 20 mph and the motor began to miss fire and buck. If there would have been someone following me they would of hit me in the rearend due to the sudden slowing of my vehicle.
