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.

The contact owns a 2005 Buick Lacrosse which was purchased on 10-14-2006. The headlights would work intermittently. The dealer made necessary repairs to the headlights by adding an unknown sensor, however a short occurred and the headlights have failed completely. The horn was also inoperable. She also stated that the water pump failed and was replaced by the dealer. All of the repairs were covered under her extended warranty plan. To date, no repairs have been made to the headlights to correct the failure. The failure mileage was 26,000 and the current was 78,000.

The contact owns a 2005 Buick Lacrosse. The contact noticed that the oil level on his vehicle was steadily decreasing everytime the vehicle was driven.

LaCrosse 6-cyl

  • Automatic transmission
  • 5,000 miles
The contact owns a 2005 Buick Lacrosse. While driving between 20-30 mph, the vehicle hesitated when the accelerator pedal was depressed. The speed would increase after driving 3-4 miles. When the vehicle was started after being parked for hours, it idled roughly and the "traction control" and "engine power reduced" warning indicator lights illuminated. The dealer reprogrammed the PCM, but the failure continued. The vehicle was taken to another dealer and they were unable to determine the cause of the failure. The failure mileage was 5,000 and current mileage was 15,800. Updated 3/19/08 the consumer stated the vehicle runs rough and would not go over 40mph. The dealer performed brake pedal recall. The consumer stated there was a clunking noise in the steering column. Updated 03/19/08
