What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
Air bags failed to deploy and seat belt mechanism failed to work. Injured shoulder from seat belt & hit head on visor/windshield. Car was flat-bedded to auto body shop. Airbag sensors were crushed in collision & seat belt mechanism was fully intact. There was about $15,000-20,000 worth of damage to the vehicle.
Brake failure - loss of pressure/fluid. Brake lines from master cylinder to abs distribution block corroded and ruptured. Luckily, failure occurred just after returning home, maneuvering in the driveway. I have contacted gm to open a case and seek diagnosis/repair. Vehicle is in tn; not a high snow/corrosion area.
Service air bag is on and every one on line has the exact same problem. It is on all the time. Air bags wont work until fixed.
Speedometer is not working and due to research on internet it is a common problem with this make and model vehicle. Dealer will not rectify problem as a recall.
I have a 2005 chevy avalanche that I am the original owner and have recently had a problem with the speedometer not working correctly. Some days it works fine and other days it doesn't work or the speed is all over the place. I have heard this has been an issue on previous year models and gm has not done a recall.
The speedometer in the electronic dash locked up while driving in a snowstorm. This left it difficult to determine my speed resulting in an unsafe condition.
