2008 Cadillac CTS: headlights failing or too dim

Filed Jun 28, 2025 · VA

I haven't had a problem with my car and my truck. But my main concern is the LED and laser headlights almost every new car and truck that comes equipped with them. Even the aftermarket replacement bulbs and light assemblies, they are way too bright at night. Blindly bright. I have to put my hand in front of my eyes and face to reduce the amount of glare. I feel like these headlights can be a safety hazard to drivers at night.

During the day my right headlight does not come on. There was a recall on this but I was told my VIN# was not included in the recall. I don't understand, if I have the problem, why would they not include my VIN# and repair the problem.

The problem started with the timing chain, which LED to coil issues and catalytic converters issues which LED to low head beams constantly burning out. Everytime work is done it causes a chain reaction to other parts in the car that requires more and more money. Now the engine light is still on and I am told that since the first catalytic converter was repaired, the second one now needs replacing and the low head beam on the passenger side has wiring issues that will not allow the new bulb to burn, I am told that the wiring appears to be spliced. The catalytic converter was replaced in april and so was the low beam bulb. Headlight was replaced in april, 2015 it is not working today and was told by dealership that the wiring had been spliced or burned out. Radio speakers do not work and all was centered around issues with coils and catalytic coverters.

While I was a passenger riding on a major interstate, in the right front passenger seat, the air bag light (on/off) on the dash/console turned from the "on" status to the "off" status. After stopping we followed onstar's directions to turn off ignition and restart the vehicle and sit in the passenger seat once again. The air bag light stayed in the "off" status. We turned the vehicle off and restarted once again. This time when I sat in the passenger seat the air bag light changed to the "on" status. The following week, my mother was a passenger in the front and the air bag light stayed in the "off" position. Last week, another passenger was in the front passenger seat and the air bag light remained in the "off" position. I took it to a dealer while out of town, and the mechanic said that the right front passenger presence module has a short and needs to be replaced. I had the front right headlight assembly replaced, but was uncomfortable allowing that dealer to replace the passenger air bag sensor. I am bringing it to my dealer to have it replaced under warranty.

Low beam headlights periodically will not light when ignition turned on, or they can go dark after working correctly, or only 1 or the other low beam light might go dark then come back on, while driving.
