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

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.

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.

11/26/2024 Crash ODI #11627455.0

[XXX] my car failed to let me use the brake, i was going about 45mph and when i went to apply brake pressure the pedal was so stiff i couldnt use the brake. Causing from end collision, when i made a trip to springdale to have my car inspected it didnt make it, started backfiring and dying around 65 mph then the motor blew, it had some issues starting but nothing like what happened within that few seconds. Im out of a car now because it drove perfect and i never have to give it thought. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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.

At routine oil change appointment (71000 miles) plus my concern to check out a noise during cold startups, Buick dealership tech noted no oil on dipstick. They recommended oil consumption test, discussed possible need to replace pistons @ $3200 and told me to return in 1000 miles to reassess. On leaving the dealership, my check engine light was lit (no warnings/lights/ driving performance issues prior to leaving the dealership that day), I immediately turned around and they re-ran diagnostic screen, reported to me that it reported nothing different than the one run earlier that day, told me again to return in 1000 miles. Approx 100 miles later, my engine suffered catastrophic damage, leaving me stranded at a stoplight intersection. I feel lucky that this happened in a safe town in broad d

Car burns 1 qt. Oil/ 1000 miles excessive oil consumption requires pistons and rings to be replaced --- many gm 2.4 liter engines have this problem. This first happened under warranty but we did not realize what the problem was until the 5 years was just passed. However it was still under 60,000 miles when I brought it in for an "oil consumption test".

11/03/2020 163,247 mi ODI #11372918.0

The 2012 Buick regal consumes a quart or more of oil in less than 2 weeks or 300 miles. I am putting a quart in it just to get it to read on the dip stick and more if needed. As it consumes oil, the engine gains a noticable ticking noise with a rough start. All of this is noticed while driving on a highway or rural road. The back right tire and or tire area makes a thumping noise at all speeds. The tire is not the issue. The stabilitrak warning light comes on often . I am the 3rd owner to the car with with 164,333 current miles. The car has had routine oil changes etc by all owners.
