BUICK Complaints

The contact owns a 2018 Buick Regal TourX. The contact stated that the driveline rear differential unit was leaking fluid onto the garage floor. The vehicle was taken to the dealer, and the dealer replaced the rear differential pinion seal. The manufacturer was not made aware of the failure. The failure mileage was approximately 27,483.

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

This car has front and back wheels differential issues. I bought this car last month and was on the highway when I heard loud clicking noises and tried to reverse and almost hit another driver. I took the car to 4 repair shops and was told to send it back to Carvana or Buick because of mechanical issues where Pep Boys decline to repair for they didn’t have the heavy equipment so I finally got the car towed for the fifth time to Faulkner Buick in Trevor’s PA where it’s currently at! Also I found out from Buick that they car had a major brakes and rotors problem that I didn’t did for as I stated I just bought this car last month and was not put 100 miles on it and I can’t afford to get it repaired! Carvana isn’t supportive of the above issues and I want my money back asap!

The contact stated the warning lights were then unilluminated. The contact stated that the following day while the vehicle was parked and turned on, the power steering warning light illuminated and the steering wheel seized. The contact stated she called a tow truck to tow the vehicle to the local dealer and while she waited she was able to steer the steering wheel; however, she did not feel safe driving the vehicle and it was then towed to a local dealer. The dealer informed the contact that the diagnosis was that the vehicle needed to update the power control module(PCM) software. The vehicle was repaired. The manufacturer was made aware of the failure and informed the contact the failure was not covered under the warranty. The failure mileage was 92,968.

At highway speeds with the Adaptive Cruise Control engaged, the brakes are heavily applied when other vehicles or obstructions are not observed. ACC engaged on controlled access highway no vehicles or obstructions and random hard braking takes place. Vehicle has been taken to the dealer numerous times for this condition and dealer reports no problems.

Had an oil change done 6/13/22. 6/21/22 Temp gauge rose to 3/4 mark, AC shut off, car really hot under hood, loss of power, car threw crankshaft position sensor code which we replaced. Had the temp gauge do it few more times from 6/21/22 to 8/13/22 when temp gauge did the same thing and car really hot under hood, smoke from tailpipe and loss of power. Took to repair shop, they want to replace engine, oil lines, turbo and gaskets. Car has 121530 miles on it.

Rear vision camera or monitor does not provide adequate view of objects directly behind the vehicle, especially during daylight hours. Even moderate sunlight causes severe fading of what the driver should see on the monitor. The problem is exacerbated by inability to make any significant adjustments of contrast. One day at about noon, while moving my Buick from the driveway to an on-street parking space, I very nearly ran over a toddler who was on a walk with his granddad. The toddler momentarily escaped the supervision of his granddad who was several yards behind him. The toddler was not within my sight when I walked behind my vehicle to reach the driver's door. He apparently ran ahead of his granddad, turned a corner and was waiting behind my vehicle for his grandfather to catch up. I now had a toddler standing right behind my vehicle, who was nowhere in sight when I approached the car. Nevertheless, these things happen. I put the Buick in "Reverse", activating the back-up camera. I checked the monitor which should have given me a view of the toddler, but it did not. Fortunately, I did not rush to back into the street. Instead, I paused to carefully establish that no traffic was passing behind me. As I looked to my left, the granddad was waving his arms, indicating that I should not back up. As I put the Buick back into "Park" I realized that a neighbor working in his yard across the street, ran up to the rear of my vehicle & picked up the toddler to bring him to safety. Fortunately, the neighbor's efforts were unnecessary, as the vehicle remained motionless until the toddler was safely out of danger. Despite my best efforts to maintain safety, this incident could have ended in tragedy. I am angered that a device installed for the purpose of preventing exactly this incident, failed to perform in the manner in which it was intended. An internet search found other complaints regarding the picture quality of the back-up camera on this 2017 Buick Enclave. Thanks

When stopped on a incline and you step on brake the transmission will go out of gear ,then when you start off you have to hold brake till transmission engages, it is really scary , I have almost rolled back into another car several times . Went back to place we bought the car new , they said it must be a safety feature, it is not ! My wife is scared to even drive , love the car except for this !
