2007 Cadillac DTS Brakes Problems

“We have an approximately 14 miles downhill run from the ski slope to I-95. The DTS does not compression brake. Cruise control will not hold a downhill speed. So I am on the brakes most of the way down. Halfway down the hill the front end starts to shake violently I am guessing the front brakes are warped from the constant use. I make it down the hill and drive onto I-95s. After 30 or so miles the brakes cool and no more vibration. This is not the first time. I asked the Cadillac dealer how to put it into compression braking and they said I cannot do that. …”

“Engine stopped. All power equipment ceased to function. I was able to get to the side of the freeway. Put the car in neutral, turned the key and the car started and continued for the duration of the 200 mile trip. The second time approximately three weeks ago my wife was driving in heavy city traffic when the same problem occurred and she lost the use of all power equipment. She was able to put the car in park and get it started again without incident. I called GM complaint department. They instructed me to take the car to a dealership and have a diagnostic test done on it. …”

“In traffic..truck in front of me, applied brakes and did not have any.,.stepped on gas and had no response..swerved to avoid crash..drifted into a parking lot and car came to a stop after several minutes started car and slowly drove home. As car unable to go more than 20 MPH..not the first time..twice before...was driving and again no brakes...gas pedal not responsive...no warning lights on dash at any time. Taken to dealer twice...they could not find anything wrong. I am afraid I will be killed or will kill someone because I can't control the car as I never know when this will happen.”

“After prolonged and continuous braking, car will pulsate or shake as if the brake discs are becoming warped. Is obviously connected to heat buildup, as normal braking is not affected.”
