Recently reported ELECTRICAL SYSTEM problems on 2006 Cadillac DTS

The drivers side headlight shuts off and on or flickers - most noticeable during night time driving. our dealer, ed shults chevrolet, advised us that this particular model of the cadillac cts was not under recall. we wanted an explanation as to why when all of the testimonials from other 2006 cadillac owners reported the same problem. they dealer stated it had to do with where the car was manufactured. the total charge to us was $901.80 to replace the light + labor. this was probably happening all the time we were driving but we only began to notice it during night time driving, most especially driving back from the buffalo international airport on the thruway. we live in the city of jamestown, ny so it wasn't really noticeable because of the city lights. after that, we were more diligent when driving at night and discovered0 it was on a daily thing. that was very scary.

My wife and i turned on our seat heaters, and both noted a smell of burning wire and plastic. we evacuated the vehicle. i then proceeded to check under the passenger seat where the smell was coming from. i visually noted a small amount of white smoke. i have since pulled the fuse for the heated/cooled seat module, and repaired it. there should be a recall on this if not i'm almost sure a class action lawsuit will be in gm's near future for such a dangerous fault. upon replacement of the module i note several burnt wires and melted connectors on the module. not even a week after i replaced the module it happened a second time! this time there was even more smoke and i was sure there was a fire. there wasn't; just burning wires again. dealers charge upwards of $800.00 for this repair!! a high price to pay for not wanting to be set ablaze for warm of ventilated seats just for it to disastrously fail again! do something about it gm! *tr

This 2006 cadillac dts was purchased used in november of 2011. at the time of purchase the vehicle only had 30,743 miles, was lightly used and never involved in any accidents. the vehicle currently has approximately 69,000 miles. a couple of months ago, i noticed the right side hid headlight flickering and going out while driving. thinking it was a bulb, i spoke to the dealer by phone who advised it may be a bulb, ballast or loose connection. from research and dealer conversation, i learned it was a costly and time consuming repair just to replace the bulb, due to design issues requiring removal of the entire bumper cover just to access the headlight. i took it to the dealer for repair, but was told that they could not duplicate the problem. since then, the flickering has gotten worse, now affecting both headlights. they randomly flicker off and on while driving proving to be a distraction to me, as well as drivers of other vehicles. it is also a safety issue as there is no warning when they are going to go out. a search of this issue via google reveals this is not an isolated instance with my vehicle, but in fact, is very widespread with many documented cases mirroring my situation. cadillac / gm to my knowledge has not offered any relief to an issue that is obviously a defect. per the dealer, repair of the ballast could be well over $1000. however, reviewing other's experience, there has been little success in finding or repairing the issue. cadillac is supposed to be a flagship for gm and a premium automobile. i would think reliable, safe and functional headlights would be a minimum threshold for safety. i ask your assistance in reviewing the documented issues from many frustrated cadillac owners who experience the same issues that i am having and exert some pressure on gm / cadillac to rectify this known issue. *tr

Tl* the contact owns a 2006 cadillac dts. while driving various speeds, both headlights and tail lights flashed and lost power. the failure recurred on numerous occasion. the vehicle was never diagnosed or repaired. the failure mileage was unknown. updated 02/02/15*lj

My 2006 cadillac dts hid headlight will intermittently, but not frequently, shut off. you can restore the headlight by just shutting the headlamp off and back on. my understanding is this is a common problem with the early gm hid systems included on the cadillac and corvette. i believe this is due to a design defect. there is no indication this will occur and there is no warning on the dash of any kind. you simply have diminished view suddenly which is a risk to being able to see what is in the roadway. *tr

Continued problem with left headlight going out. *tr
