Headlights normal (low) beam intermittently go off while driving, usually individually (both left and right) and on occasion both have gone out although sometimes one goes off, don't realize it at first until the other goes off. . There is no commonality (for example, can happen on smooth roads, on bumps, but also can go over bumps and lights stay on) and when the headlight goes out, the only way to get it back on is to turn the lights off and on. This happens whether using the automatic light feature or having them manually turned on. This has been going on for over a year. I've seen similar complaints online for this particular car, and gm appears to have done a recall for similar cars in their Buick and other lines but not for Cadillac.

While driving at night on I-70 my headlights when out. I pulled off the road for a minute or so and they started working. Occasionally they will blink and then settle down. In investing this on the computer I discovered this happens frequently on this model. I think the mfg. Should announce a recall on this defect. Visualize driving at 65 mph in total darkness.

When headlights are on auto, or manual, the lights flicker, turn off, shut off while driving. I have to turn the headlights off and then back on thus far. I find this to be a safety issue and don't know the cause, have contacted general motors to find if there are issues known to them.

We had to open the front passenger door and look for the shoulder. We don't drive this car after dark. I don't understand why this issue has not been recalled.

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.

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.

Continued problem with left headlight going out.

My lens covering is discoloring and has become clouded over. This was brought to the dealers attention under warranty. He said this is not covered. How can this be when now the headlights are significantly less effective through this cloudy lens. Other Cadillac owners in the dealer hear my conversation and they had the same problem. They had the lens replaced at a cost of over $350. A blind eye seems to be a true safety issue that should be a recall item.

The left headlight will turn a rose color & then go out. The right is o. K. I bought the car used last July & possibly the right has been repaired already. The high cost to change a bulb is because of the design of the front. The inner fender & the front fasica has to come off to access the ballast or bulb. I think g. M. Should pick up the cost for headlight repairs.

Headlights flicker on and off then one or both will just go out.
