I was driving along a city roadway when the vehicle's stability, traction control, and engine light came on simultaneously when all of a sudden the vehicle just stopped, almost causing the car behind me to collide with my vehicle. I called the dealer, lawley's gm store in sierra vista, az. Where I had just purchased the vehicle and told the service manager what happened...he sent a tow truck to pickup the vehicle and after inspecting the vehicle at the dealership told me it was the throttle body needing replacement...I bought a new one and had it installed. Ran fine for a couple of weeks after which the vehicle began stalling while driving on a city road when the same thing happened again, but this time when the vehicle stopped without any warning causing the vehicles behind me had to swerve around me almost causing accidents with oncoming vehicles. Called the dealer again, had the vehicle towed in and this time was told that the vehicles computer was not programmed right and that it also needed throttle body harness...bought the harness and had it installed as well as the dealer reprogramming the computer. Car did well for a few months when it happened again (vehicle stopping unexpectedly), this time approaching a major crosswalk and once again causing the vehicles behind me to come a abrupt stops, fortunately a city police vehicle was on the opposite side of the crosswalk and the officer witnessed what happened, put his vehicle's emergency lights on and came over to help me push out from the street to a walgreen's parking lot where I once again called the dealer, had it towed to dealer where they told me the throttle body pin connectors had to be soldered on which they did. Car is running ok for now, but I am concerned that I may be driving and the vehicle will once again stop unexpectedly and cause an accident.there are consumer posts on this problem on the web.

I own a 2005 cadillac sts. I notice a loud rattling noise followed by sluggish and stalling engine while in the midst of driving. I took the car to the dealership and told me there was a problem with my timing chain. While at the dealership at least 3 other cars of the same type complained of the same problem. This is not safe while the consumer is driving and the car begins to stall at 55 or 60 MPH. This repair costs over $3100.00.
