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. This began july 6th and is happening more frequently as in several times a day.

What owners say
Driving my daughter from school on I 95 in connecticut near stamford at approximately 12 midnight, and noted chimes related to safety alerts following a particular strong bump in the road. First alert was that the ABS and suspension system was inactive, next airbag was not functioning and then electrical charge was low. Attempted to find a safe place to stop the car; eventually all warning lights came on and all systems in the car began to fail - could not open windows, could not contact onstar, lights inside the car, speedometer, hazard lights, turn signals and the headlamps. Eventually used street lights to guide us to exit on I 287 in white plains, ny. Once we found a safe spot off the road, we turned off the car, because we did not know what the issue was (?engine, ?fire risk, ?would power steering / brakes fail next). Car towed at ~10 am to local cadillac dealer.
I as driving on a farmed market road (f.m.) approx. 55 MPH. And the right headlight lens flew off the car. Luckily there wasn't any other cars behind me, and there wasn't any damage to my car and/or anyone elses vehicle. After I returned home, I checked the driver's side lens to discover it was loose as well.
Noticed that one passenger side headlight was out, but I still had the high beam. A few days later both were out. Went to auto parts store to have them put in new bulbs and they noticed the that plastic cover was missing and they said that caused the bulbs to short out. From reading other complaints I'm afraid I will have to pay hundreds for a new assembly when all I need is a plastic cover.
Headlamp lenses cloud reducing nighttime visibility for driver and for other vehicles. Polycarbonate lenses discolor and turn yellow. Problem is pervasive across most makes and models. Replacement lenses are very costly. The problem did not exist when glass headlamps were used, and replacement was inexpensive.
1.both front headlight lens/covers fell off. One recovered. Adhesive attaching cover to headlight was still on cover, hardened; no adhesive is on headlight assembly. No signs of stress to headlight or surrounding bodywork. 2. Driving in rain causes all four bulbs in headlight assembly to fail with resulting instantaneous loss on headlight (high and low beams) and turn and position lights. 3. Bulbs replaced, recovered cover epoxied to headlight assembly, headlight assembly with missing cover needs to be replaced. Parts, except failed bulbs,currently installed in out of service car.
Tl*the contact owns a 1998 cadillac deville. The plastic lens of the exterior headlamps developed a yellowish tint over time, which reduces visibility while driving. The contact took the vehicle to the dealer and they stated that they would attempt to clean the lens. If that remedy fails, the contact will have to replace the exterior headlamps at the cost of $300 each. The failure mileage was 65,000 and current mileage was 66,000.
For years I have been frustrated by the lack of rear illumination of gm vehicles during rain or fog driving conditions. Drivers seem to think that they do not need to turn on headlights because they have daytime running lights. They probably do not realize that the drl's only illuminate the front of their vehicle. Gm should inform drivers that when headlights are required, daytime running lights do not suffice.
Tl* - the contact has a 1998 cadillac deville with an odometer reading of 133000 miles and both headlight units are cloudy. The contact said that the visibility is very poor an there is no way to clean them to improve visibility. When making a left turn it becomes difficult to see. The contact took the car to the dealer (caramgo cadillac) and he was told that both head light units need to be replaced.
Headlight lens falls off.
