“During winter driving, turned on the heated steering wheel, felt the fingers of my left hand begin to burn and noticed smoke coming from the heated steering wheel cover. I immediately switched off the heated steering wheel, the smoking stopped. I have not used that feature since, have not had it repaired. Checked for recalls on this problem, did not find any.”

“My 2005 Cadillac Deville loose steering power when turning for about 20 second to 1 minute about 20 times in 3 years. This happens during the first couple miles of driving. Cad dealer can not confirm problem as it is erratic and only happens once in a while. I noticed that this usually happened when the weather is high humidity and I parked the car outside at night or during rainy day.”

“My A/C runs at will. Off and on by itself. Running, stationary, and in motion. My headlights come on when I put the car in drive ever though they are turned off. My alternator was replaced and the battery and all checked out fine at two local parts /battery stores july 18th 2017. Both were replaced in may of 2016. The display panel for the A/C shows both the fan icon and the auto icon. The auto icon will not turn off. Searching on line for complaints about this make and model show many others with this problem and no answers. …”

NHTSA complaint #11006296, filed 2017-07, 125,000 miles

“Engine began to leak oil after 40000 miles. The company and dealership assured me this was normal. Longer I operated this car, more it began to leak. At first few drops, then later, 1-2 qts between oil changes. Today, it is worst. I have spent several thousand dollars related to this engine. The leaks continue to this date. Engine stopped once on me, shut off, nothing worked. No airbag, any electrical service. Hit hole in road and everything shut off. Called company many times, wrote to president, other executives all to no avail. …”

“Driving on a local freeway, my ignition switch to off. I was only going 55 MPH in heavy traffice. I was able to place the car in neutral & restart the engine, but for a short period I was with limited braking and steering. Had my wife been driving I am certain the outcome would not have been as good. After this I took the car into the local Cadillac dealer to have the ignition switch corrective recall complied with. They adjusted the size of the hole on my keys - this was the fix. However, changing the size of the key hole does nothing to prevent my ignition switch from popping' to off. …”
