Vehicle Speed Control Problems of Cadillac STS

Certain times while driving, the traction assist comes on, and all power is lost to the engine. Lights are still on, car is still on, but gas does not accelerate and car is hard to steer. I have had to pull over 6 times in the last few months, turn the car off, restart and hope it does not happen again.

Driving home on the interstate at the posted 70 mph speed my electronic stability light goes off and the cars engaged suddenly begins to rapidly power down. A few moments later I was unable to maintain 40 mph as the transition revived to 2x normal levels. I was forced to pull off the interstate and turn off the car for a few minutes, restart the car and drive while the transition light remained light up. Over the past couple weeks the electronic stability light/engine powering down situation has become more frequent and almost a daily situation I expect--not a comforting feeling when on the interstate. I took the car the a local mechanic today and for once the transmition light was not on and the traction stability situation was not a problem--go figure. Anyway, the mechanic tested the car and said the issue appeared to be moisture getting into the accelerator sensor and causing the issue. He was not 100% sure and recommended I keep driving the car and bring in once the issue pops up again--sure it will. Difficult to prove without being an expert mechanic but I believe there is an engineering defect with the car creating this issue and the part should be recalled and replaced with a newly engineered moisture sealed part. All acceleration issues like this are very serious as gm should accept responsibility to fix. I replaced the same sensor approximately 2 years ago and problem persistent over that same period of time. Not what you expect when you invest in the Cadillac brand.

My wife went to the local gas station and as she was pulling in she made a right hand turn past the pumps to park. She hit the brakes and the car sped up. She slammed them harder and it slightly slowed down but she hit 2 guard rails and then crashed into the cinderblock wall destroying the front bumper, both front fenders, headlights and the internal aluminum bumper was crushed as it was designed to do. The air bags did not go off but she was not hurt. She said the car sped up while the brakes were deployed. Also, after she hit the wall she tried to put the card in reverse but she had to put it in neutral to actually go in reverse. The car is at the mechanic being fixed at this time but I am concerned about this speeding up instead of stopping when the brakes are applied. . . This is not a good thing and the insurance company said it was up to me to find the cause. Someone from Cadillac or NHTSA needs to come and look at this before the car is fixed.
