The contact owns a 2007 GMC Sierra 1500. While driving 60 mph, a loud banging noise was heard coming from the rear of the vehicle. The contact was able to pull the vehicle over to the side of the road. Upon inspection, the rear of the vehicle discovered that the rear passenger side leaf spring fractured and was hanging on top of the axle. There were no warning indicators illuminated. The vehicle was slowly driven to an independent mechanic who diagnosed that the rear passenger and driver side leaf springs were fractured. The leaf springs and brackets were replaced on the vehicle. The vehicle was not taken to a dealer for diagnostic testing or repairs. The manufacturer was notified of the failure and referred the contact to NHTSA. The failure mileage was 125,000.

While driving the vehicle at a rate of 20 mph and started stopping and notice the brakes where going out. I had then lost brake pressure altogether. Used the parking brake to get stopped after putting the vehicle into neutral. I had the truck towed to my local independent mechanic and he checked the vehicle and found all the brake lines to be rusted out, and had lost all brake fluid. Upon finding this he found the majority of the undercarriage to have severe rust damage an several parts also.

This is a constant and ongoing issue with the vehicle. When driving the vehicle on the highway or road at speeds above 15 or 20 mph the front suspension will shake violently when hitting bridge expansions, any sort of road bump, man hole covers with minimal edges, etc. The violent shaking in the suspension will then stop and not be felt during normal smooth highway or road travel but recurs each and every time road bumps are encountered. The shaking is violent and feels as though the whole front end of the vehicle is about to fall off. This has been happening for more than a year now. I have had the vehicle examined by the dealer and independent shops and they all say the suspension components all look intact and in good service condition.

The contact owns a 2007 GMC Sierra 1500. When the pavement was wet, the vehicle would begin to fishtail and aggressively turn 180 degrees. The dealer stated that nothing could be done unless the pavement was wet. They gave her the option to trade in the vehicle for a different vehicle, but she declined. The dealer then advised her to look in her owner's manual and call NHTSA. She stated that the dealer would not even keep the vehicle to inspect. The failure mileage was 12 and current mileage was 11,000.
