  • 38,000 miles
Cracks in dash cover around air bag and over instrument cluster. No hard road hits, no junk on the dash. Heard a rattle, looked up there and found the cracks. Thousands of incidents across internet. Seat tracks rough sliding and motor failure. Outside mirror motor failure. I am the only driver and dont move seats much. Lack of use kills motors? rear window leaking water due to plastic frame shrinking, cracking and leaving a gap. Only took the window out once before finding it leaking 2 years later due to the plastic frame shrink and crack. Door handles paint falling off in flakes. Fronts replaced by dealer at 17K. 38K rear handles started doing it. Dealers unwilling to do anything after 36K. 78K on truck now, making last $575 payment this month and truck needs thousands in repairs. I would have thought buying a 45K truck and using it as a family traveler it would be the last one I would have to buy since it is well cared for. These trucks are now know for problems and less appealing. Selling it isn't easy because of these continual issues GM failed to address. The truck was discontinued in 2013 most likely due to mfg defects and complaint ratios. All GM trucks have these issues from 07 through 2013.

Cracked, broken dashboard. Cracked in 2 corners of the passenger air bag. Crack goes all the way across to the drivers side. A section around the speaker has completely broke off. Cruise control no longer workers. Some speakers work sometimes, other times other ones work. Makes horrible rattling sound. Dealership says won't cover it and a new dash is over $800 for parts.

On 10/13/2015 I took my Avalanche to galles Chevrolet, albuquerque, nm for repair of a cracked instrument cluster and faulty L/R door lock actuator. I picked it up on 10/15/2015. While parking the truck on 10/17/2015 I shut off the engine and suddenly there was no power to lock the locks with the key fob. It was as if the battery I had had replaced new about 6 weeks prior suddenly went dead. Then I heard a clicking noise in the doors/lock actuators and suddenly the battery power was restored. I next experienced this problem while driving on New Mexico hwy 485 on 10/25/2015 only worse. While driving for about 10 miles at speeds of between 35-50 mph the door lock actuators locked and unlocked the doors numerous times, the airbag, stabilatrac, and ABS sensor alarms kept activating and the cruise control suddenly disengaged many times again while driving. When we reached our destination about 10 minutes later I turned off the ignition and immediately lost battery power and heard the same clicking noises in the doors and needed a hotshot from another driver to get restarted. We were able to drive home in the darkness with all equipment and lights working without further incident. On 10/26/2015 I experienced another incident of sudden sensor and lock activations and alarms while driving in traffic and the hwy. This went on intermittently for about 10 minutes and then stopped. I had the battery, charging system and fault codes checked by a Firestone mechanic 2X on 10/26/2015 but no faults were found in the computer and the battery and charging system checked out good. The technician mentioned that the only possible explanation was that the battery or one of the computer modules was somehow losing its ground contact but he checked each of ground contact wires and found each securely connected. I will try to take a video of these events if it occurs again.

Especially when ignition key switch is engaged it will stick and cause the starting motor to remain engaged requiring turning the switch back to off position then trying to restart the vehicle. Being careful not to hold the ignition switch key in the position necessary to engage the starter any longer than absolutely necessary to hear the engine fire then returning the key position to the run position seems to prevent the problem.

  • 88,000 miles
The contact owns a 2009 Chevrolet Avalanche. The contact stated that while driving approximately 75 mph the vehicle stalled, then automatically restarted independently. All of the warning lights in the vehicle illuminated after the failure and the door locks began erratically functioning. The vehicle was taken to the dealer for approximately one month however, within that month they were unable to duplicate or diagnose the failure. The manufacturer was contacted and offered no assistance. The failure mileage was approximately 88,000. The current mileage was approximately 92,000.
