  • 65,000 miles

A D V E R T I S E M E N T S

The contact owns a 2009 Chevrolet Avalanche. The contact stated that the vehicle experienced independent deceleration and stalled while driving 75 mph. The stabilitrak warning indicator illuminated. The vehicle was taken to the dealer where it was diagnosed that the accelerator pedal assembly needed to be replaced. The vehicle was not repaired. The contact received notification of NHTSA campaign number: 16V381000 (air bags); however, the part to do the repair was unavailable. The manufacturer exceeded a reasonable amount of time for the recall repair. The manufacturer was notified. The senior adviser informed the contact that GMC was planning to rescind the recall for the takata air bags. The failure mileage was approximately 65,000. VIN tool confirms parts not available.

Avalanche

  • 60,000 miles
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.

Avalanche

  • 91,650 miles
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.
