2006 Cadillac DTS: headlights failing or too dim

Filed Mar 17, 2024 · Electrical, Lights · IA

Driving at night on I-29 South and headlights went off intermittently but not simultaneously. Headlamps continued intermittent cut-out until reached destination (approx 3 hours later). As a safety issue for driving while dark, had both assemblies replaced at Cadillac dealer for approx $3,950.00. Replacement was Cadillac recommendation as it was stated the electronics do fail in these headlight assemblies. After replacement and as a follow-up, new assemblies were installed and are not sealed against the elements. In February 2024, on a 5,000 mile trip, drove several hours during cold, snowy and raining conditions. Both headlight assemblies had a considerable amount of moisture inside the lens housings (see photo). Cadillac dealer did replace one of the new headlight assemblies due to moisture accumulation in assembly under parts warranty, but not both.

Both headlight assemblies are operating without incident since replacement, except as noted above on assemblies not sealed against environment/elements.

I bought this car, and the steering wheel controls(audio/cruise control) have not worked, prior owner was advised to replace the bcm. Front driver's headlight intermittently goes on and off when driving. The steering wheel switch to adjust the height, angle, and settings for each driver also are not working. Apparently these are known issues. I had similar issues with my 2000 chevy impala, and my 2004 chevy impala ss.

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.

Head lights go off by themselves while driving, either the left one or the right one. Sometimes even while sitting in the garage warming up the vehicle the headlights will start to flicker and then one will go out. Shut off the light switch weather its in the auto mode or off mode and lights will come back on and my go out again. Very dangerous when driving. Been going on for months now and cadillac dealer says they have no idea what the problem is and no fix. Why not a recall from gm as a number of others with the same vehicle are having the same problem

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.

Headlight ballast failure due to poor headlight design with housing etc... Causes headlights to shut of while driving due to moisture. Happened at night. I have seen numerous reports about this issue and curious as to why no recalls?
