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.

I turned a corner, drove through some sand on the road and broke traction. After that, the traction control system lights came on and within several seconds the check engine light came on. I had onstar service run remote diagnostics and they found ABS failing and a cylinder misfire. The car took an immediate loss in power and started to shake at all power levels.

My new Cadillac with only 6700 miles on it had to have a brand new engine put it because of bad pistons. This is a very common thing for Cadillac Ats models. If you go on the Cadillac forums website, you will see many other Cadillac owners having the same problem.

There has been 2 occasions my brand new car has stalled and lost power. Both times the car has sat for over an hour. When I get into vehicle it starts up and I take off. Within a minute the vehicle is stalling and fails to accelerate. Each time I have taken it into Cadillac and they can't find a problem because it did not register in the computer system nor does a test drive discover problem. The real concern is if I'm crossing an intersection and the vehicle stalls and I'm in an accident. I don't want to be a statistic waiting for GM to find this problem.

ATS 4-cyl

  • 7,250 miles
The "check engine" indicator came on, soon thereafter, "stabilitrak" and "engine power is reduced" indicators came on. Ten minutes later, the car shut down in the middle of the highway. After 10-15 minutes, the car started up again with the "check engine" light still on. Car was repaired at a Cadillac dealership. Service representative advised that it was necessary to solder some wires/terminals behind the right rear wheel well fender liner. A service bulletin (pie0291B) identified this problem. This same exact problem arose in mid-February. The remedy at that time was to replace the throttle body. Hopefully, this new remedy will work now that there is a service bulletin to assist with the diagnosis.

ATS 4-cyl

While driving the car at about 15 to 20 miles an hour the car came to a complete stop. There was a total shut down of the electrical system. The emergency blinkers could not be engaged, the car could not be shifted. The car was towed into the shop, the dealer advised me the engine failed and a new engine was put into the car by the dealer. We have owned the car for two months.
