Headlights failing or too dim by model year

What owners say

Filed Jul 27, 2025 · Electrical, Lights · GA

There is a water seal leak around the driver side headlight. I have photos showing proof of standing water. It has now caused the headlight, left turn signal, and drivers side brake light to fail. My passenger side headlight is doing the same. I have no headlights, no driverside lights period. I drive 2 children around in this car and it's gotten very dangerous. I contacted GM, and the local dealership and they won't fix it. I'm a [XXX] and don't have the $3200-$5000 I was told the repair would be. It is a problem in certain GM models, Cadillac Srx 2010-2015 having the same issue and the recall being fixed for those drivers. So, I have no choice but to drive around with no headlights, no left blinker, and no driver side brake light with two you children. I have to work and have no other options. It's a catastrophe waiting to happen, I live in the metropolitan area of Atlanta, Georgia. Please help me with this, I am terrified to drive this car around. I've had two people flag me down at a red light to let me know my brake light is out which is terribly dangerous and if it starts raining while I am out I have no headlights. This has become an emergency situation for me and my children. I have photo proof of the water pooling inside the headlight assembly. The seal is so bad that even covered the condensation pools inside the headlight. Please help me get a dealership to fix this issue. They want to charge me $275 for diagnostics and this is already and issue on this model car, reported by many drivers with the recall on the Cadillac. They need to fix it before I end up a casualty to this problem. Thank you so much. I can send a video of the emergency flasher and signal not working. I replaced the headlight in January and the new one never worked. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

2nd bad headlamp assembly that develops moisture and causes lamp to go out. First was passenger side now driver side

Filed Sep 26, 2023 · Lights · WI

The driver headlight assembly has water in it and unable to fix it without replacing whole assembly that can be as much as $1500. The light bulb and valance was replaced. The valance was filled with water. The headlight still wouldn’t work. Upon further investigation there is a part sealed into the assembly that also has water in it with no way to get it out or replace. This is a safety risk since i am unable to see on driver side in dark without my light. There are no recalls but have found many complaints on same issue. The part water is in is sealed and shouldn’t have a way for to get in. The only fix is replacing entire assembly. I have no light at all on that side until fixed.

I previously reported an issue with a he condensation in the driver side headlight which every one of these models with the hid headlights has this issue. Now it is becoming a safety issue as both headlights are doing it and are randomly going off while driving I almost hit a telephone pole with my infant in the car this is an extremely common issue with these vehicles and Buick has no fix they even stopped producing the replacement headlights this is an extremely dangerous issue I’ve made both nhsta and Buick aware of these issues and if nothings done to rectify them and something happens I will pursue legal action

The headlight area had condensation in it that resulted in water in the headlight. This caused the headlight to go dark. This is a safety issue as one of my headlights is not working. I can’t see that section of the road or adjacent sidelines. Very dangerous particularly at this time of year with deer running into road from the side. There are many other regal owners with this problem which can be verified by googling the problem. This is the second time the light has failed for condensation. Other drivers and pedestrians are at risk because they cannot be seen with the headlight out. Headlight was replaced once and has failed again. Cost to repair 2 years ago $1600 new estimate $1800. This is for one headlight but recommended to replace both.

The driver side headlamp assembly has a faulty seal which allows water to leak inside the housing under normal daily conditions. When this happens the water leaks down through the assembly where the headlight ballast is mounted, causing water to collect in the ballast, and killing it (making the headlight go out) as well as the electrical components that power the L.E.D. daytime running lights also making those stop functioning. There is no quick and easy fix for this, as the headlamp assembly must be replaced to restore the headlight because even replacing the burned out ballast will only provide light temporarily again until that too is again destroyed by water. Because there is no good alternative available with an aftermarket replacement, I was forced to purchase an entirely new assembly which cost $1,505 and took months to save and be able to afford. This is a manufacturing flaw that should have been recalled and addressed. My warranty does not cover any damage due to water, so I had to pay for this myself, along with many many other people with the same issue. Having my headlight randomly stop working was a dangerous situation to be put into.

Headlight housing leaks water into headlight. This appears to be a problem with this vehicle as I read numerous complaints about this.

Filed Jun 19, 2021 · Lights · VA

Issue with the condensation/water getting inside our HID headlights. Have replaced once and now they are both full of water again. Dealer refuses to cover as a defect. VERY expensive to repair. Huge safety issue because lights can fail at any time going down a dark road! Safety to thers as they may not see me coming.
