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.

The front headlights get water in them and fogs up. . Causing your headlights to look dim at night.

12 Headlights problem

Failure Date: 04/19/2019

Both driver and passenger headlights constantly show condensation/water in the headlight assembly after it rains. At one point, the condensation caused the premature failure of the hid ballast, an loss of headlight. In viewing a Buick Regal forum, this seems to be a common problem on this model car and gm should be responsible for fixing the problem. Vehicle can be stationary or moving. Rain causes the faulty headlight seals to show the problem. Happens on a regular basis when it rains. Images to large to send.

13 Headlights problem

Failure Date: 03/01/2019

Condensation issue in drivers side headlight. This is a manufacturers defect as thousands have complained about this issue and nothing is being done. The entire hid headlight assembly cost $1,320. 95 at the dealer without taxes. This is appalling to me that I should have to pay for this problem when clearly this is a manufacturers defect. This is a very serious safety issue. My car did not even have 45,000 miles on it when the headlight went out.

14 Headlights problem

Failure Date: 12/17/2018

Tamara recall I noticed that there was water in the front left headlight and as I was driving down the road the bulb burnt out. When I took the light out the water ran down into the ballast this the second headlight that I have brought and the same problems exist. This is very dangerous especially driving on a back dark road I did research on this problem and I noticed everybody was having the same problem. Gm had discontinued the headlight because they was aware of this problem. I think they should replace these headlights as it is a safety concern.

15 Headlights problem

Failure Date: 06/19/2018

My hid headlight assembly has a seal leak, causing moisture to form in it every morning which results in the headlight electrical and headlight to burn out. The first time it was the drivers side, now the passenger side. The consequence is that inadequate lighting may reduce the visibility of the driver, thus increasing the risk of a crash. It should have been under the manufactory warranty.

16 Headlights problem

Failure Date: 06/03/2018

I have had problems with the stabilitrak - check engine light / multifunction indicator light coming on at random times (the on star diagnostic report doesn't give any indication of whats going on with the car so that regular people can understand before going in talking to a dealer about the issue) - powertrain issues I have had to replace my battery when I bought the car I was told it was newer and shouldn't have issues. My driver side headlight is full of water. There have been so many issues with this car yet no recalls have been found on my particular car. I read reviews from others and the 2012 Buick Regal just seems to have a lot of problems consumers such as myself should be entitled to a huge portion of cash paid for the defective vehicle. I thought it would be a safe family car but it just didn't turn out that way. I was afraid to take my family in my car for 6 months because I didn't know if I would we would be stranded. When I took my car to a certified dealer to get it repaired it was worse my car shook while I drove. Buick just isn't the car for me or anyone until they are able to create a safe car. Aesthetically newer model Buicks are nice but mechanically they are a bust.

17 Headlights problem

Failure Date: 01/01/2017

Takata recall I noticed that the driver side light keep getting condensation in it I noticed that everybody who have the GS model has condensation in causing the ballast to fill with water and causing the bulb to burn out and the ballast and bulb have to be replaced because of water entering into the headlight.
