2012 Buick Regal Lighting Problems

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

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.

The contact owns a 2012 Buick Regal. The contact stated that after starting the vehicle, he became aware that the electrical system was not functioning properly. No warning lights were illuminated. The vehicle was taken to the dealer, who diagnosed a failure with the body control module. The vehicle was repaired, but the failure reoccurred. After investigating the failure, the contact related it to NHTSA Campaign Number: 12V093000 (Exterior Lighting), but the VIN was not included. The manufacturer was notified of the failure but provided no assistance. The failure mileage was 16,000.

Moisture in headlights causes light to fail while driving .

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.

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 contact's uncle owns a 2012 Buick Regal. The contact stated that the front headlights were burned out. The contact was unsure whether there was a warning light illuminated. The contact did not provide further information.

The manufacturer was notified of the failure and referred the contact to the dealer. The vehicle was not repaired. The failure mileage was unknown.

The contact owns a 2012 Buick Regal. The contact stated that while driving at night, the illumination from the headlights was very dim. The contact had taken the vehicle to an independent mechanic and was informed that condensation had accumulated in both headlight modules causing the failure. The dealer was notified of the issue and informed her that they would call her back. The manufacturer was not notified of the failure. The vehicle was not repaired. The failure mileage was approximately 82,000.

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

MY PASSENGER HEADLIGHT WENT OUT AND DID KNOW TILL I GOT A TICKET. I HAVE TAKEN IT TO A REPAIR SHOP FOR REPAIR TWO TIMES AND THEY FOUND THAT IT IS NOT SEALED PROPERLY. THERE IS CORROSION UNDER THE HEADLIGHT ASSEMBLY DUE TO IT COLLECTING WATER. HOW CAN THIS BE FIXED I HAVE HEARD THAT THIS IS A BIG ISSUE PLEASE ADVISE ON WHAT CAN BE DONE TO HELP EVERYONE AFFECTED.

IN THE 2 YEARS I'VE OWNED THIS VEHICLE, I HAVE HAD TO REPLACE BOTH REAR TURN SIGNAL BULBS 4 TIMES. THE SOCKET LOOKS MELTED. ON OCTOBER 3, 2020...THE FRONT PASSENGER SEAT ADJUSTMENT STOPPED WORKING. IT CAN RECLINE BACK, BUT NOT RETURN TO THE UPRIGHT POSITION

CONDENSATION/WATER GETTING INSIDE HID HEADLIGHT OPTION TF4

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.

BOTH HEADLIGHTS WENT OUT WHILE DRIVING AT NIGHT. MECHANIC TOLD ME I NEEDED NEW BALLAST.

CONDENSATION IN HEADLIGHT CAUSING THE BULB TO QUIT. GET NEW BULB FOR $150, CHANGE BULB, IT RAINS, IT HAPPENS AGAIN. AM TOLD A NEW ASSEMBLY IS $1500. THIS IS A COMMON ISSUE WITH THIS VEHICLE. SEEMS LIKE IT SHOULD BE FIXED BY BUICK.

WATER SEEMS TO BE LEAKING IN HEADLIGHTS, CAUSING BLOWOUT HEADLIGHT HID.

HID DRIVER HEADLIGHT ASSEMBLY BECAME FULL OF CONDENSATION AND STOPPED WORKING. QUOTE FROM DEALER TO REPLACE ENTIRE ASSEMBLY IS $700 PLUS LABOR.

BOTH HEADLIGHTS LET WATER FROM RAIN IN. BOTH HID BULBS HAVE BEEN REPLACED SEVERAL TIMES. I'VE HAD HEADLIGHTS GO OUT AT NIGHT. HAD TO PARK CAR AND CALL SOMEONE TO COME PICK ME UP. GM NEEDS TO FIX THIS PROBLEM BEFORE SOMEONE GETS KILLED FROM THERE HEADLIGHTS GOING COMPLETELY OUT AT NIGHT AND CAUSING AN ACCIDENT.

RIGHT HID HEADLAMP ASSEMBLY CONTAINS MOISTURE AND PREMATURELY WEARS OUT BALLAST. EVEN AFTER REPLACING BALLAST AND REMOVING MOISTURE IT HAS SLOWLY STARTED TO REAPPEAR ON THE INSIDE OF THE HEADLAMP ASSEMBLY.
