What 2011 Chevrolet Avalanche 1500 owners say
Most recent owner complaints, unedited.
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.
Takata recall; no gm remedy from tn chevrolet dealers. Live in martin, tn. 38237 notr: below date field will not allow prior year date; recall +2 years outstanding with no remedy via gm to date.
Takata recall - my airbag is under recall and I contacted my dealer who does not have a replacement or knows nothing about how I can get a new part. I am fearful to drive the vehicle. Takata
Dash is cracked on driver and passenger side.
2011 chevrolet avalanche has dashboard cracking all around the passenger side air bag. My concern is if the air bag is deployed for any reason the hard plastic dashboard material will shatter a scatter all through the cabin injuring myself, or worse my family. My understanding after reading all the reviews this is not a concern of gm even though most vehicles have this issue. It seems they are simply waiting for enough people to get injured before they have to do a recall due to using inferior products. This was my first chevrolet and will be my last, what a disappointment.
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
General motors dash cracks on various avalanche model years. My research suggest other gm vehicles similar too the avalanche. My meticulously maintained avalanche is typical. Comparing too other gm vehicles of other owners. Crack are near identical in location. Presently one at the passenger airbag. Second crack on the instrument dash hump. I can only conclude the possibility of a design flaw. Crack picture are the best I can do. Airbag crack is near the quarter. Two pictures show the vehicle is not abused. General motors contact have proved useless. "if I want the crack repaired, I would have to pay from my own pocket."
My dashboard right above the drive seat instrument cluster has a large crack and getting bigger. Possible safety issue when traveling the vibration of the road increase cracking
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.
