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.

2009 Cadillac CTS Owner Comments

Service traction control and reduced engine power came on the display. Vehicle runs and idles roughly even when in park. Took the vehicle to a mechanic and was told to call Cadillac dealer about a special coverage adjustment: Throttle body-reduced power mode. GM #14582. Looked up this special adjustment and it states it is on 2008-2011 Cadillac Cts models. Called local dealership and was told it had been determined that because my car was not manufactured in a specific plant, it was not included. My car is doing exactly what this special adjustment covers and I am not eligible to have my car repaired because of where it was built? I was told that I could have a GM certified dealership verify the issue and then call GM experience rep. If I was not satisfied with results then I could call GM customer service and ask for help paying for the repair. I should not have to pay for a repair that has already been documented and is currently being fixed on other Cadillac Cts vehicles. This needs to be repaired across the board as obviously this is not just a faulty part put on vehicles in specific plants or with specific parts.

While driving car jumps out of gear causing rapid deceleration, loss of traction control, stability control, power steering, and brakes. When this happens the instrument cluster looses any indication of gear selection, and car must be shut off and restarted several times to regain controls once parked. GM/Cadillac is aware of the issue since they have a tsb relating to the fault code, but no recall, even though this is a severe safety concern. It has happened several times at multiple speeds highest of which was about 45-50 so far. Have had into shop 4 times. They have replaced a detent, which did not fix the problem, and internal mode switch twice within approx. 2-3 weeks apart neither time has fixed the issue. Now they are wanting to replace the transmission control module, which I have not had done yet since I am not confident in their ability to correct the issue and the cost is well over a $1000. Currently looking into legal recourse, since I have a vehicle that is pretty much a lemon and not safe to drive my children in. Cadillac has refused to grant a goodwill repair even though the issue was addressed 3 times under the cpo warranty. I have been looking online and have seen several recalls for similar issues but different model years. Not sure how rapid deceleration, loss of power steering and braking does not qualify as a recall necessity.

We were leaving a diner parking lot in the afternoon, when I had to stop for a delivery truck blocking our exit. When the truck pulled forward I lightly pressed the accelerator and the car began to surge forward and to our left(my wife was in the car with me). I pressed down on the brakes and the car continued forward and began to turn to the right and I tried to steer the car to the left but the steering did not respond resulting in my hitting two parked cars. I had the car towed to the Cadillac dealer. The dealer indicated that there was nothing wrong with the car and suggested that the surge was caused my a secondary car mat but could not explain the steering problem. This same situation occurred during our severe snow storm last winter. At the time I assumed it was due to icing conditions on the road and my dealer indicated that they had reset the car codes to correct any errors(stability control light stayed on)
