After purchasing my vehicle through a bank loan, the frame started to deteriorate resulting in suspension components to come loose and fall off. Lastly, rear driveshaft broke off, leaving me inoperable.

The vehicle was sold with significant rust damage to the underbody of the truck. The truck parts are rusted to a point the suspension, and axel are about to fall out. The truck is leaking gasoline due to the amount of rust. The power steering that they fixed after one day driving it had issues when sold is still having issues leaking fluid. It has been deemed unsafe to drive on road. The dealership sold the vehicle in unsafe conditions, and will not rectify the situation. I have documentation, and photos of the damage to the vehicle.

Brake lines rusted out. Apparently this is an issue for this year and many other model year vehicles. Considering the brakes stop the vehicle, this is a big safety issue, and very expensive to be fixed.

I was recently involved in an accident where I passed out while operating my vehicle. I believe that carbon monoxide poisoning was the contributing factor that caused this accident. Faulty exhaust manifold fasteners seems to be an issue that could have caused this accident. I was shocked to see that there is no recall for this problem. I have incurred numerous personal expenses due to the accident, but feel lucky that there were no serious injuries or fatalities. I am writing this to call attention to the issue in hopes that you will do something to keep this from happening to someone else who might not be aware of the issue. I am disappointed that there has been no recall on this product. The vehicle is totaled, but could still be examined to find the cause.

Heated seat comes on by itself all the time. It has burned my father's rear end. I checked it out and it came on 12 times in 5 minutes. My father is older and did not realize he was burning until it was too late. I was told by three different dealers that there are no safety recalls for this. Upon reading help forums, I discovered they do have a recall. I am waiting for a response before I take any further actions. Thank you

Driving down the road the truck engine will be running with no abnormal sounds, smells, leaks but will act as if not in gear. Rpm's will rev but truck will not move. Only after putting truck in park (lots of grinding noises) then pressing the 4wheel button then back to 2wheel (sometimes through two cycles) the truck will back into gear and operate properly. Took it to a transmission shop put it on the diagnostic machine and no error codes were given to give reason why the transfer case disengages randomly. Replaced the transfer switch per shop recommendation "just in case"it was okay for about a month then once again issues started again just the same as before.

The airbag indicator light is on and off. Took it to serive centers the light came off for a week then came back again. Mechanic told me the spring coul needs to be replaced got it replaced but the problem is still the same. When ithe weather is cold the lights comes off when its warm the lights are one told the mechanics they said its the connection they tried to fix light will come of for a few days then back again. The second problem is the engine light - they told me its the fuel ejection pump got it replaced but not resolved. I keep taking tthe truck back to the service centers but after a week the light indicators are on. I also failed my inspections due to this problem. The only reason I pass is that it has to be fixed but after inspection the lights are on again. I have read all complaints about this problems but gmc motors doesn't have an active recall for it its just a communication stating the problem. The truck is still running but this safety issue needs to be resolved by the company. And I think thats part of the reason tgey dont make the avalance anymore.

Rear brake lines burst while I was in motion. I was going down the highway and had to use the gears to slow down. They were corroded through. Same thing happened in 2016 with my fuel pump line corroded through. Was leaking while I was driving. Did not notice for a few days until there was puddles of gas where I park. Over the past few years my cladding has been falling off from rust through on the bottom secure points.
