NHTSA defect investigations
Federal safety investigators have looked into a possible defect involving the 2011 Chevrolet Avalanche:
Desiccated Air Bag Inflator Rupture
From 2000 through 2017, Takata produced millions of air bag inflators using two types of phase-stabilized ammonium nitrate ("PSAN") propellant -- propellant 2004 and propellant 2004L. After prolonged exposure to high temperature cycles and humidity, inflators using propellant 2004 can degrade, causing the propellant to burn too quickly when ignited.
What 2011 Chevrolet Avalanche owners say
Air bags all 55 →
February of 2021 I was notified the driver side air bag in my truck I drive daily has an issue that if goes off can cause serious injury or death. that as 6 months ago and still no path forward to fix it, how safe it this for me to drive is death is an option? I feel this would be a concern for drivers and the companies doing more to prevent something if a part cannot be secured. Maybe start offering deals to accept the trade ins so your customer doesn't have to drive around an unsafe vehicle because of supply issues? This needs to be addressed so something silly can be avoided.
Was advised of the recall of my vehicle on Feb 26th 2021 and that the part to fix the problem was not available it is now six months later and have heard nothing and don,t know how log they expect people to wait with a faulty part to be repaired.
Body & structure all 23 →
The structure that holds the rear differential and axle to the frame rusted through and broke off from both sides so the whole rear axle unit broke loose and pulled back so the drive shaft pulled loose and the rear tires were rubbing on the fenders. If this happened at highway speeds I don't know what might have happened. The vehicle was towed to a welding shop to see if it can be repaired. It has not been inspected. If it can not be repaired the vehicle will have to be junked. There was no warning that this would happen.
Tl* the contact owns a 2011 Chevrolet Avalanche. The contact noticed that the front passenger side dashboard was fractured directly above the air bag. The vehicle was taken to dan vaden brunswick Chevrolet Cadillac (121 altama connector, brunswick, ga 31525, [phone]), but was not diagnosed or repaired. The contact received notification of NHTSA campaign number: 16V381000 (air bags), but the part needed for the repair was not available. The contact stated that the manufacturer exceeded a reasonable amount of time for the recall repair. The contact stated that the vehicle was taken to the same dealer three times and the part was not available each time. The manufacturer was made aware of the failure and scheduled an appointment at the same dealer and provided a case number: 9-5453255979. The approximate failure mileage was 80,000. VIN tool confirms parts not available.
Transmission & drivetrain
Purchased a used 2011 Chevy Avalanche with 87,000 miles one owner from a small dealership. After having the vehicle for about a week noticed it shuddering when pulling any kind of grade. Thinking it was some kind of misfire had all the plugs changed only to find that it also had an oil file problem with 1 of the cylinders. When the vehicle would shudder it was around 1500-2000 rpms. If I would give it more gas it made it past the 2,000 rpms and would shift with no problems. Needless to say the transmission is now toast as it gave out completely and needs replaced. No warning lights of any kind made me aware of a potentially serious problem. After reading more I am seeing that the transmission is something that GM has not fully taken care of as stated with older models. The transmission failed while driving on a major interstate roadway while nearing the top of a hill. …
When I am slowing down to a stop the transmission will suddenly make the vehicle surge forward quickly. If I not just as quick to apply a firm brake I risk hitting the car or pedestrians near me which has happen on several occasion. On one occasion, as I was turning into a parking space the vehicle suddenly surged forward so forcefully that it cause the front left bumble to travel outside the planned path and hit a brick column. This problem only occurs in situations when I am slowing down, I.e. Making turns, traffic lights, parking, etc. It can be frightening when it occurs unexpectedly. Recently took into local Chevrolet dealer. They acknowledged the problem and said Chevrolet engineers are working on a fix where the transmission's computer is altered. But they didn't seem confident in the outcome.
