2006 Cadillac DTS acceleration problems

Filed Apr 23, 2022 · Acceleration, Electrical · GA

I called OnStar because my car would not start and they sent someone from GM. The guy looked at my car, could not identify the problem, so I got it towed to a repair shop. Ends up, I had to replace the transmission. The repair shop ran electric test on the vehicle and no codes or issues. My dash is now reading service power steering and this is a safety issue that needs to be fixed by the manufacturer.

I bought this car, and the steering wheel controls(audio/cruise control) have not worked, prior owner was advised to replace the bcm. Front driver's headlight intermittently goes on and off when driving. The steering wheel switch to adjust the height, angle, and settings for each driver also are not working. Apparently these are known issues. I had similar issues with my 2000 chevy impala, and my 2004 chevy impala ss.

( just bought this used car , first time driving it home from dealer) speed control was set at 70 MPH on I-88 started down a steep hill, speed keep going up . I keep my foot on he brake as the speed was up to 85 MPH . The car never slowed down. I have had cadillacs beginning in 1991, never had a car do this before, if you are on a flat road doing 50 MPH, take your foot of the gas the car will start slowing down after you drive 3/10 of a mile and than slow very slowly. There is something wrong with this car, after driving for 50 years all makes and models , I never had a car do what this car is doing. There is something wrong for sure.

I turned right out of my place of employment. I was less than a half block from the light. I pulled into the center lane intending to turn left at the light. Suddenly my car accelerated rapidly. I slammed on the brake so hard my leg hurt for days. The car accelerated more and the brake did not stop it completely. I rear ended a large pickup. I went back to my office and contacted cadillac customer service immediately. I requested they check the "black box" computer module. They did eventually do that but said they found no problem. Nobody seems to be listening to what happened. I offered cadillac to just trade me for any identical car they refused any kind of help. I eventually sold the car at a great loss. I had to buy another car, my insurance has gone up dramatically and I am more than discouraged. I was terrified every time I drove the car I had loved before. I constantly drove with one hand on the steering wheel and the other hand on the gear shift in case it happened again hoping it would stop it to shift into neutral.

This happened 6 times. My engine speed would not drop after foot removed from accelerator. 4 of the six times was on freeway exit ramp. I verified that the floor mat was not in any way interfering after the firstime this happened. I contacted my dealer 3 times - central cadillac, and they said they checked and found nothing wrong and that it must have been my floor mat. I know it was not! I don't believe this to be cruise control related as it happened in city traffic twice. When exiting the freeway after braking to stop engine would stay at 1800 RPM to 2300 RPM dependent on occasion. The same RPM range was in city also.

An example of the cruise control concern is as follows; if the cruise control has been engaged at some speed,lets say 40 MPH and then disengaged and the car decelerates to say about 30mph then engage the cruise control again instead of smoothly accelerating back up to the previously set 40 MPH the car abruptly accelerates and sometimes downshifts and the speed can go up to 45 or 50 MPH before it settles back down to the preset 40mph.this seems to be a very random occurrence and cannot be always duplicated. The speeds at which this can occur are varied. This unexpected acceleration can be very upsetting and I believe in some situations may even present a dangerous situation.

Cruise control does not maintain speed downhills within reason. Freewheel on all downhill grade as fast as gravity allows. Easily can go 15-20 over set speed on normal highway conditions. First vehice owned with this condition. Potential safety and speeding ticket problem. Dealer states thats the way it is. Fix is don't use cruise when there are hills per owners manual.
