- My dashboard has had a large crack in it for some time now and I am needing it to be repaired as I am not the only one with this issue. - The dashboard is considered the cover for the instrument/control panel of my vehicle. It is not in good shape due to this crack which would cause a greater hazard should the air bag deploy and cause the dash to send pieces of plastic flying everywhere. - This problem has already been brought to GM's attention in a lawsuit. - It has been inspected by myself and other passengers in the vehicle and a cause for great concern since I have no idea why the crack even appeared after having taken care of my truck very well since the first day I've owned it. - No warning lamps that I am aware of but then again, not sure if issues I've faced since owning it are due to this crack.

I drove to work & parked my 2007 Avalanche in my employers truck garage as I do every day. I went into the office attended a job briefing & we put on our coveralls for work then we got ready to leave to go to the 1st jobsite but as soon as the 1st two coworkers walked out of the shop they turned around yelling that my truck was on fire. I didn't believe them at 1st because I had just parked like 15 minutes prior. Parked & not running. Well I looked and my whole engine compartment was full of flames. We used 4 fire extinguishers to put the fire out & the fire department arrived to finish. My vehicle was totalled & I only had liability insurance.
I used my factory remote to unlock the truck the ignition sparked twice and then went on fire, for no reason it just started burning the entire steering column and all of what is around it burned up we used a pitcher of water to put the fire out, I contacted GM and was advised there was no recall for this. It can not be common for a car or truck to just ignite unlocking the doors we are grateful that I was not in the truck and just suffered burns to my hands trying to put the fire out if not my entire home would have been in flames.
Takata inflators:my air bag light came on, it was reset and came back on a short time after. I have electrical issues with cruise control, radio and fan for heat and A/C.once in s while I get a smell ofburning wire. My transmission began bumping on acceleration several months ago also when cranking it move forward a bit in park. The transmission bump is when accelerating, the electrical issues are random, the airbag light stays on.
Vehicle caught on fire and/or exploded while sitting in apartment parking lot. Vehicle was not running and had been sitting for at least 30 minutes to an 1hr. Was in bedroom, when notified by the fire dept. That the vehicle was on fire.
The engine has a hesitation due to a manufacuring problem it also uses more oil than it should between oil changes. Also having problem with the electrical system every time I turn around something stops working like the side mirror on the drivers side won't fold in like its supposed to and the backup sensor stopped working. Tried to get our mechanic to fix it but it needs a code to get into the electrical system and GM won't give it to anyone but thier own mechanics. So now we have to go to the dealership to have it fix which will cost alot more. About amonth after purchase the dash got a small crack around the passenger air bag. This is our second 2007 Avalanche the first one had no problems at all and I had no idea that this model had so many problems that the manufacturer won't fix. …
