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).

When I turn the car off the key will not allow me to remove it from ignition to the proper position to remove the key. This is a safety hazzard. I have to mess with the brakes, steering wheel and parking console and keep starting and turning off the car to get key removed. The dealer said they could not locate the problem however several of your other gm vehicles are having this issue. Please assist. I am being stranded in the dark in the cold with a car I cannot leave the key in or someone could steal the car, the doors will not lock with key in ignition.

November 24th 2024 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 I soected 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.

Hello, I am the original owner of my 2019 Buick Regal sportback which shows a "shift to park message when I attempt to shut off the car and the car shifter is in the park position. I am unable to turn off lights, radio, or accessories. This condition runs down the battery and prevents me from starting the car as the shifter stays locked in position unless the car is running. This should be covered under the gm drivetrain warranty. Please help.

The two systems that failed are the airbag release on the front passenger side and the stabilitrak system. Both systems show error lights on the dash. The front seat passenger does not have airbag protection. The stabilitrak system error light appears intermittently and when the traction system goes off the car brakes almost stop the car while driving. We go to royal Buick in tucson, arizona. We worked with germaine kendrick. I've attached the dealer service invoice dated April 14, 2023. The invoice summarized the problem and stated that 1) a new seatbelt assesmbly is needed and 2) the service technician states that they can not replicate or repair the traction problems. Today is June 11, 2023. We are still waiting for the seatbelt assembly to "arrive". There is no solution for the traction system. We have phoned and texted 4 times. The most recent conversation on June 5th with "chris" was interesting; chris stated that the seatbelt part was never ordered and furthermore, is not needed to repair the airbag warning light problem.

Left headlamp assembly and driver’s window regulator were replaced under warranty and now need replacing again! trim strips were replaced under warranty because they were rusting and now they are all rusty again! electrical system now blows fuses. 2103 Buick Regal turbo just reached 60,000 miles. How many times will I have to spend $2,000 to fix the faulty left headlamp assembly which was going on in 2011 & 2012? there’s complaints all over online!!!! I haven’t been able to go out at night for 6 months because of no front headlight!!!!! I have been to 3 Buick dealers and they all have no idea how long this $2k light assembly will last because it should have been recalled!!! the lastest Buick dealer was trying to steal my vehicle by saying the “check engine” light indicated that I am going to have all kinds of problems with my turbo or engine (he wasn’t sure what it was) and that my car was not worth keeping!!! I should get a new car! I asked him how much to take care of the engine problems and he said $3,500. So with the supposed engine problem & headlamp, that’s $5k. I should buy a new car per dixie Buick in fort myers, FL!! the other dealerships said it was likely just a sensor since the car was not running rough and there was no hurry to have the “check engine” light looked at by their mechanics!!! they felt waiting 2 weeks until they could schedule an appointment for me was fine. Buick needs to recall their left headlamp assembly which was a known problem years before manufacturing their 2013 Regals and get rid of their sleazy ripoff service rep’s!!!.

While driving the vehicle, I received an alert message on the instrument panel that stated “remote not detected,” then the vehicle immediately shutdown in the middle of the road. I lost all power to the vehicle, I couldn’t put the vehicle in gear, neutral or anything to get it out of the road. I immediately replaced the key fob battery, no change vehicle didn’t start or power didn’t return. The vehicle had to be towed. After a couple hours power was restored and the vehicle started up again. I have replaced key fobs, had the dealership replace the car battery and the problem persists. This appears to be a defect, could you please advise on how to proceed with dealership?.

Condensation is getting in the high def headlamps, and causing headlights to blow. It's a known issue and the assembly is between $1,200 and $1,500 dollars.

The contact owns a 2019 Buick Regal. The contact stated that when he attempted to start his vehicle there was no battery power, no clicking sound of the ignition. The contact stated that the vehicle dash was blank as well. The contact stated that he had the vehicle jump started and the vehicle ran normally. The contact stated that the "check engine" light had illuminated and then turned off after the vehicle was turned on. The contact also heard an abnormal "whistling" noise coming from the engine compartment. The contact stated that the dead battery failure is an ongoing failure. The contact had taken the vehicle to a local dealer, where it was diagnosed and determined that the battery and electrical system were in working order. The vehicle had not been repaired. The manufacturer had been informed of the failure. The failure mileage was approximately 6,000.

My car has had suspension issues for 2 years and I have repeatedly taken the car to the dealership.

Projector lights in headlamp assembly go out and moisture gets into headlamp causing poor visibility after sundown or poor weather. General motors case number: 9-10416199921.

Dear NHTSA, I am submitting a formal complaint regarding a 2019 Buick Regal, which I purchased as a used vehicle in 2023 with approximately 19,000 miles. Since owning the car, I have added only 14,000 miles, yet I have experienced multiple significant and ongoing issues that raise serious concerns about the safety, reliability, and warranty service associated with this vehicle. Vehicle problems: suspension issues: shortly after purchase, the car has had persistent suspension problems, which negatively affect stability and ride quality. The dealership has replaced multiple suspension components, but the issue continues and remains unresolved. General motors (gm) initially agreed to cover these repairs even if my warranty expired and also stated I would qualify for a vehicle buyback. They have now backtracked and are refusing to honor that commitment, despite the ongoing unresolved safety issue electrical and transmission malfunctions: I have reported intermittent electrical and transmission issues to the dealer. These include erratic shifting, hesitation, and occasional system malfunctions. Each time, I have been told they cannot replicate the problems, so no repairs have been made. These issues are intermittent, but they occur while driving and are potentially dangerous. Delays in repairs and warranty coverage: the dealership delayed parts ordering and repairs for my suspension concerns until after my warranty expired. This delay appears to have been intentional, potentially to avoid honoring warranty coverage. Refusal to service due to location (puerto rico): I live in puerto rico, and both gm and the dealership have stated that they are limited in what they can do for me because of my location. For example, I was told they cannot order a replacement windshield to puerto rico, and that what they can do based on a buyback or warranty coverage is limited. I have been patient and waited for the dealership and gm to make things right for 2 years.

There is condensation and moisture present inside the high definition front headlight assemblies, which causes the headlight illumination to be diminished and created a visibility hazard while driving at night. The vehicle was taken to the ganley Chevrolet dealership who diagnosed that the front headlight assemblies were faulty and needed to be replaced. The cost to replace both is about $3,000. Then I went to damper's automotive of cleveland ohio for a second opinion and after replacing the bulb in the passenger side headlight, the bulb immediately blew. Based on complaints from other customers this is a known issue on low and high mileage vehicles of the same make and model. It's a astronomical cost to replace these assemblies and they could go out at any time while driving due to the trapped moisture and-or electrical wiring exposed behind the headlight.

After heavy rain in mid-September 2022, both headlights just stopped working. The dashboard will usually display a warning or pop up symbol that something is not working, but I had no warning and got pulled over driving at dusk with no headlights. There has been been other issues with this vehicle too! the other issues include: bluetooth connection not working at all, the transmission has “jerking” issues while changing gears and the engine revving too high while only going 30mph while driving in suburban massachusetts. The car has less than 70k miles, these issues should not be happening. The main issue is the headlights, considering they cost around $200/ea and just stopped working with no notice.

Car lost all electrical power while driving (moving) and fully shut down, stalling immediately. Nothing electrical worked, including 4 way flashers. The alternator was just replaced 2 weeks after this same full loss of electrical power was diagnosed when going to start the car while parked. The battery was fully recharged at the repair shop and deemed ok. I had my road service come out to address the issue. Before they arrived, I was able to restart the car. The service tech checked the battery and alternator. Both checked ok, but the battery was almost drained and did not show signs of any dead cells, despite it having been able to restart the car shortly before the road service arrived. We replaced the battery. Car is in the shop now. The safety risk is full loss of power while moving resulting in no brake lights, 4 way emergency lights, full stall, loss of power steering and brakes that can lead to a collision on the highway. This type of problem has been reported on numerous Regals.

My car continues to run on battery. I’ve had the battery and alternator replaced.

On my way home from purchasing the vehicle, the car began to lose power and I noticed black smoke though the rear view mirror. Another driver signaled me down, so I pulled over and realized my car was on fire. The fire was in the engine compartment from what appeared to be the exhaust manifold. Since I was in a residential area, I grabbed a water hose and began to diffuse the fire. The fire department arrived and forced my hood open to reassure the fire was out. Luckily I was able to make it out safe. But I strongly believe my life and the lives of other drivers were definitely in danger.

Vacuum pump blew up forcing cam shaft sensor to blew out of engine and caused my brakes to fail. This happened at a stop sign. I proceed through the stop in front of a semi-tractor. Fortunately it was in front of the police station in(30mph) town zone and he was able to brake before killing me. My vehicle stopped before going through the front door of an auto shop, my timing cam is damaged and shepherds is quoting $2600 to replace, plus an additional $800 already spent in replacing the vacuum pump. I’ve driven the car an additional 6 months with the cam sensor detached but the vehicle stalls when I slow or stop. This has caused additional hazardous situations. Person(s) will die if this defect is not addressed, it’s probably already happened. I have over 25 years in automotive safety systems design and manufacture, this needs addressed immediately.

After shifting the vehicle into park and shutting off the engine I get a warning light on the dash that says shift to park. Even though the vehicle is already in park.

When I shift the car from park to drive it does a very hard jerk. And vehicle has no codes on dash or anything.

We purchased this vehicle in may 2016 and from the beginning had strange issues with the engine. It was in and out of the dealer with them trying to figure out the exact problem. They could not, so they contacted gm for approval for an engine replacement. We were concerned about going this route but were assured it would be taken care of for the life of the car. After the replacement in July 2016, the car seemed to be better but other weird issues arose. The engine always made a squealing noise that we were told was fine. We have done all required maintenance, recalls, and regular service. For the past 2 months, the car has had strange shifting issues. It was taken in to be looked at and nothing was found. The transmission received its' routine maintenance on schedule. It still was a problem and we were told to drive it until a code appeared. The car got progressively worse and had great difficulty shifting, which had us involved in a few close calls. Took it to a different dealer that also didn't find a problem. They said since there was no code, but seemed transmission related, they would drain it and replace the fluid. This also didn't work. We continued to drive the car and almost ended up stranded in the middle of the night while driving the freeway. The car became almost uncontrollable. We made it home. But, the following day while driving it to work, the car was jerking, stalled, and then lost the capability of reverse and neutral. We had to have it towed and a new transmission put in. We were told by the dealer that there was an explosion in the transmission, and we were lucky we were somewhere safe when the car died. It's very frustrating paying for a vehicle that didn't seem right from the beginning. We have put well over $6,500 in trying to repair a car that seems like it was never right in the first place. We have been fortunate that neither of us, or any of our children, have been hurt considering the major issues with our car.

The contact owns a 2012 Buick Regal. The contact stated that the vehicle would not immediately start-up, and while at a stop light the entire vehicle would shake and vibrate. The cause of the failure was not determined. The local dealer and manufacturer were notified of the failure. The VIN was included in NHTSA campaign number: 20v764000 (suspension) however, the part to do the recall repair was not yet available. The contact indicated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The failure mileage was 72,000. Parts distribution disconnect.

While the vehicle was driving, there was a loss of power, at that moment sparks was seen emanating from under the hood, then the vehicle completely stopped running. Once pulled over smoke was bellowing out from the hood and subsequently ignited into flames. Fire department was dispatched and fire was extinguished. The vehicle was towed away and is still at the tow yard. The tow operator, based on visual inspection stated the fire did start in the engine compartment and spread to the fire wall, totaling the vehicle.

Front headlamp burned out due to moisture in the assembly. There is an issue with the ballast in the headlamp assembly for the turbo model. The seal may be faulty due to the headlamp shorting out except for the daytime running lights. I realized that it had malfunctioned and there was moisture in the assembly itself. My repair shop quoted $1500. 00 for the repair/replacement as the whole assebly needs to be replaced. This is definitely a safety hazard and a common one for this make and model. This should be a recall due to the faulty headlamp assembly.

Condensation in driver side headlight now headlight will not work bought a new 112. 00 buld and still doesnt work. Looked issue up on internet and found hundreds of complaints.
