What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
On another occasion, while driving 40 mph, the vehicle stalled without warning and the driver crashed into a ditch. The air bags failed to deploy. A police report was filed. The driver sustained a concussion that required medical attention. The vehicle was destroyed and towed.
When we first got the truck my husband and I were driving at about 55 mph and went to brake suddenly and the truck would not stop, it made a grinding sound and I had to pump the brakes a few times before the finally stopped. After that we called the dealer and they said it is because the truck was new..
The contact stated that while driving 55 mph, another vehicle crashed into the contact's vehicle and the air bag failed to deploy. The driver sustained injuries to the neck and the front passenger sustained injuries to the right leg which required medical attention.
My 2005 chevy trailblazer 360 just shut off and I rolled back and slammed in to a tree on the driver side. The keys were also stuck in the ignition and we could not get them out. As we got the truck back home we had to use a crowbar to get the driver door open and take the door panel off to fix the window.
The contact inspected underneath the hood and noticed the power steering pump was leaking fluid onto the ground. In addition, the serpentine belt disconnected. The vehicle was not diagnosed nor repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 100,000.
Tl* the contact owns a 2005 chevrolet trailblazer 360. While driving 30 mph, both frontal side air bags deployed inadvertently without an impact. There were no injuries. The vehicle was not diagnosed nor repaired. The manufacturer was notified of the failure. The failure mileage was 80,000.
The contact also witnessed fuel leaking from the rear of the vehicle. The vehicle was taken to an independent mechanic where it was diagnosed that the fuel pump module failed and needed to be replaced. The vehicle was not repaired. The vin was not included in nhtsa campaign number: 12v59000 (fuel system, gasoline).
The contact constantly had to ensure that the brake pedal was applied when the accelerator pedal was released because the vehicle would independently surge forward numerous times without warning. The vehicle was taken to the dealer more than twice and they were not able to replicate and diagnose the failure.
