When I bought the car the owner told me the power steering was bad and that they would fix it. They replaced the power steering pump but it didn't fix the issue. When I took the car to get inspected so I could get it titled, it failed the inspection due to a leak in the power steering high pressure line, the rear third brake light being broke, the top motor mount failing and both the front and back wheel bearings being worn. When I took the car back to the dealership, the owner got in my face and shoved me making me leave.

All the Dts from 2007 to 2012, have a faulty 3rd brake light on the trunk. The light works when it want to and they stop lighting when it wants to.it is a factory defect.

The issue was regarding the failure of the ballasts in the hid headlights which, per ntsb and other websites, has been a significant issue with this and other GM models. The issue seems to be diagnosed generally as water backing down the headlight assembly into the ballast causing the failure. There is also a tsb on the issue: www.cadillacforums.com/forums/Cadillac-Dts-forum-2006-through-2012/173283-tsb-flickering-headlights.html and pages of the ntsb filings about the headlamps are here www.carcomplaints.com/Cadillac/Dts/2006/lights/exterior_lighting-3.shtml after being stopped twice by law enforcement for a headlamp out, we took the car to ron carter Cadillac in houston, Texas where we were charged about $850 to replace the right front ballast. The left one was also just starting to show the same problem so I made the contact to GM and was working with kim. My wife was just stopped the other day by a police officer regarding the left lamp. Kim was going to contact ron carter Cadillac and have them contact me regarding the left lamp and work out a deal on is replacement. I assume kim did her job but ron carter has never to this day called us regarding the left lamp. They also had no interest in working with GM on the original right headlight issue saying it was 'the customer's problem to work with GM'.

While driving on the interstate at night at 70 mph, both headlights flickered then turned off. The lights came back on after cycling to automatic light control switch off then back on. A few minutes later, they turn off again. This dangerous situation has repeated numerous times tonight.

Daytime running lamp (drl) / turn signal bulb appears to have melted the headlight housing. Bulb failure caused owner to discover problem. Melted housing will no longer accept bulb fixture. This seems flawed and results in a safety issue where turn signal on front of car is inoperable without expensive replacement of entire headlight housing. New housing may not solve heating problem that causes melting. This problem, and similar consequences of excess lamp heat, is reported by other owners on the Cadillac forum.

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.

Headlamps would flicker and go out intermeadly then the other night they did this and both went out I was driving on a dark road and could have had a serious accident alot of Dts owner have also reported this problem.

Like many other caddy owners are having problems with the twilight sensors operation. Problem being the headlamps come on too early and go off too late resulting in a dimming of the interior dash illumination. This causes the driver not to be able to determine vehicle speed...especially if its still bright enough out for sun glasses to be used. My 2007 Dts and others. See this link also www.cadillacforums.com/forums/Cadillac-forum/T-92975.html I had my car to the garage just today and they did nothing to fix this safety issue. Not going to argue with them any more.... something must be done to help us. The rental Dts I had while my car was in "repair" did not have the same problem yet they said my car twilight was "ok". thanks

The left headlamp assembly had to be replaced due to corrosion. Approximately a month later the right headlamp had to be replaced for the same reason. I have subsequently have learned that Cadillac put out a bulletin, document id #08014A, that addresses the problem with corrosion in the headlights. If the headlights failed out at night, in the rain, clearly it is a safety issue.
