Example complaints

Air bags: “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.”

NHTSA complaint #11022238, filed 2017-09, 110,000 miles

Other or unknown: “Dashboard cracked approximately 2 from airbag to front windshield vent causing dash to sink resulting in safety issue. Upon further investigation both online and within the fleet of the department of homeland security for which I am charged with maintaining vehicles, I noticed the same issue is epidemic exactly the same location fleet wide. Gm charging $300 to repair for their own manufacturing defect.”

NHTSA complaint #10760622, filed 2015-09, 43,000 miles

Electrical system: “I was in line at a drive through at burger king and as I pulled up to the cashiers window to pay for my food the engine started to accelerate. I put my foot on the brakes as hard as I could while the truck was shaking and lurching trying to go forward. I can't say for sure how high the tachometer was, but it seemed to almost peg for a few seconds while this was going on. Finally I jammed the transmission into neutral and the engine returned to normal idle. I say jammed because it took great strength to get it out of drive. For about 10-15 seconds this truck was totally out of my control. …”

NHTSA complaint #10593395, filed 2014-05, 30,000 miles

Body and structure: “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.”
