[xxx] from memphistn. 2006 Cadillac Dts left headlights flicker on and off, turn on manually to get them back on. Cigarette lighters seem to work when they want to. My car pulls to the left for no apparent reason, had the front end checked, nothing was found wrong with my front end, headlights were checked for loose connection, nothing found wrong but they continue to flicker when I drive at night, until I keep turning the light switch on and off. I had the cigarette lighters fixed twice, only to have the front lighter on the console to quit working for no apparent reason.

Headlights turn off by themselves without warning. They do come back on when turned on manually but continue to turn off for no apparent reason. They turn off in no particular order, sometimes one or the other or sometimes both of them. It's very dangerous because it happens without warning.

Headlights flicker and shut off everytime head light are turned on in automatic or manual modes. Headlights were replaced and problem continues. Ballast is the next step but is very expensive and difficult to do. This is a manufacturing / engineering critical problem. GM should be responsible for this repair. You purchase a car and expect a critical item like your head lights to work properly everytime.

Power points, instruments, seats periodically fail. One day seat cooler will work, others it won't. windshield wipers automatic function, "rainsense" starts normally but then stops in heavy rain requiring manual operation.

Headlamp intermittently flickers and then eventually goes out and stays out. Headlamp comes back on if switch is manually turned off or if vehicle is shut off and restarted. Dealer did not do anything to correct problem because lights were working when vehicle was brought into shop. I asked that lamp be replaced, but dealer refused and stated there were no complaints or service bulletins about this issue. There are tons of complaints on the internet about 2006 Dts hid lights or ballast failing. The vehicle has a short warranty time left so I feel that at lest the bulb should be replaced as it is the most likely cause. The service department did not document the problem or state what was done. I have called back and ask that they send me documentation and state what was done to fix my issue.

Information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6) my 2006 Cadillac Dts [xxx] has an intermittent hid headlight problem that occurs in colder temperatures. The lamps will flicker and one or the other will go out. The only way to get the headlight to come on again is to turn off the headlights and turn them on again. The vehicle has been in to the local Cadillac dealer, and is in there now, but they don't seem to be able to fix the problem. Also, the right taillight/brakelight/turnsignal will occasionally go out completely. The side-marker led lights still illuminate, but the rest of the light assembly goes dark and the turn signal in the back doesn't work. This also happens in cold weather. The dealer hasn't been able to fix this problem either. Similar problems are being documented in the Cadillac owners forum online.

I purchased a used 2006 Cadillac Dts in October of '06. In the spring of 2009, the headlights on said vehicle began to flicker. I thought it was a bad headlamp. I took it to a mechanic and they could not duplicate the problem to determine why this was happening. I've been driving the vehicle for 8 - 9 months since this problem started and now one headlight or the other or sometimes both will go out. Took it back to the mechanic and it was determined after 4 hours of testing that the ballasts in the headlight unit are both bad causing the headlights to do this. Repair cost at a non-GM mechanic was $1700 - $2000. A GM certified mechanic verified the problem and repair cost will be $1403.82. This is to replace the ballasts, headlamps and the labor costs. I feel this is a ridiculous cost for repair of headlights, but have ordered parts and hopefully will have my car repaired next week. This is very unsafe, as I can be driving down the road at night and have my headlights just shut off. The only way to get the headlights back on is to turn them off and back on, but even then it only works for a short period of time before repeating the same problem. In researching this, I have seen other internet posts from Cadillac owners experiencing similar issues with the headlights. I did complain to GM/Cadillac and they are offering to cover 25% of the repair costs. In the interim, I have been pulled over by police for having headlights not working and I have not even been aware that they had gone out while I've been driving.
