Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety.

Impala 6-cyl

  • Automatic transmission
  • 43,000 miles
In January 2004 we purchased a pre-owned 2003 Chevrolet Impala from larry puckett Chevrolet's program car fleet, [xxx]. the warranty on the vehicle was up to 36,000 miles. Until the past 2 weeks we have been more than pleased with the performance of the vehicle. On June 17, 2005 my wife, her mother and our two children, (4 yrs. And 10 months old), were traveling on interstate 85 South coming to montgomery from atlanta when the vehicle shuts down and loses all power. My wife lost all power steering and power brakes, at 70 mph she had to wrestle the wheel and stand on the brakes to direct the vehicle to the shoulder of the road. At that point, the vehicle cranks up fine and she completes the trip. Following the total power shutdown the vehicle was taken to larry puckett Chevrolet for repair. Mr. Donald barber was the associate who was our service consultant. He explained to my wife following replacement of the ignition switch that he had seen this situation before. That, was of great concern with me. Has this problem caused injury or death to another consumer? I am writing a letter to robert lange, executive director of vehicle safety for General Motors, and I will be copying the NHTSA with the letter. Thank you for any assisstance.
