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 driver side door latch became inoperable, and the brake, check engine, and traction control indicators illuminated. The contact waited for a few minutes and the vehicle restarted. The failure occurred multiple times. The vehicle was taken to an independent mechanic, but the cause of the failures could not be diagnosed. The vehicle was not repaired.

CTS 6-cyl

  • Automatic transmission
  • 80,204 miles
The contact owns a 2003 Cadillac Cts. The contact stated that while driving 65 mph, the vehicle swayed abnormally from side to side with the illumination of the stability traction sensor light. The vehicle was taken to the dealer for diagnosis where it was stated that the stability traction sensor needed to be replaced. The vehicle was repaired and the manufacturer was notified. The approximate failure mileage was 80,204. The consumer stated back in 2012, she started having issues with the stability traction engaged displaying on the screen. When the foot pedal started to vibrate, she checked the manual to find the cause, and it stated the stability traction sensor needed to be replaced. After being quoted a price, of $500, she decided to wait. But, on May 29, 2013, while driving down the freeway, at 70 mph, the vehicle started to hop across the lane, the stability traction engaged was displayed on the screen. The consumer was able to drive to the dealer, where she was informed, again about the traction control sensor. Updated 11/20/13

CTS 6-cyl

  • 70,000 miles
2003 Cts - service tracking system began to display and engage frequently. Took to local dealer and was told nothing was wrong with vehicle. Problem continued and began vibrating badly and pulling toward left (unable to brake). Returned vehicle several times before they replaced "steering sensor" $650. Two months later began to lose power immediately after start up, dealer replaced battery. While driving vehicle home problem began again. Displayed low battery, then multiple warning lights for service (ABS, tracking, airbag ect...). returned vehicle to dealer and they are currently replacing alternator. I have no confidence that this is the real problem based on what I have read on-line regarding this same issue. I also have same leakage issues from both coolant and oil sources that I have read on-line. Dealer continues to tell me to replace both gaskets and thermostat. These again are common issues that are posted consistently on-line by consumers. These are seriously dangerous failures based on people's personal safety. GM must step up and honor these safety issues by recalling these items. Inability to control vehicle due to tracking system engaging and not able to brake, vehicle losing power and stalling while driving 50 miles an hour, and lastly fire hazard due to leaking plastic valve cover gaskets.
