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.
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.

Headlights flicker and go out. If you turn auto off and back on, the headlights come back on, but do not stay on. . Right side more often then left, but both flicker and turn off. This condition was there when the car was only a year old but wasn't very bad so didn't get it fixed under warrantee. Now the problem is a safety hazard, but cannot get any dealer to even look at the problem. There was a broad recall by gm covering many other models and years, but this one wasn't listed. If there is ever a loss in headlights at night resulting in an accident, gm may finally show some interest. This usually occurs when motion however not 100%. This started back in 2007 and has been intermittent since then. This has been discussed with dealers in wisconsin and florida to no satisfaction because the car is not on any recall list for this problem.
