2016 Buick Verano problems

“I am submitting this complaint to report a safety-related issue involving my 2016 Buick Verano. At approximately 112,000 miles, the vehicle experienced a major transmission failure that significantly affected drivability. Shortly thereafter, an airbag warning light illuminated, indicating a potential malfunction of the supplemental restraint system. An independent mechanic advised that the vehicle was no longer safe or economically reasonable to repair due to the transmission failure and the airbag system warning. The cost of transmission repair was estimated between $5,000.00 and $7,000.00. The vehicle could not be safely driven, sold, or repaired, leaving me with an inoperable vehicle and an outstanding loan balance. I am submitting this complaint to ensure this issue is documented and reviewed, as transmission failure combined with an airbag warning presents a serious safety concern. Also, it’s been widely documented by other consumers of having the same problem with the transmission failing prematurely on these type of vehicles as well.”

“While driving on the highway there was a random harsh jerk on my car, and I was immediately unable to maintain safe speeds driving nearly causing a serious crash. All of the service lights (Service Parking Assist, Service Power Steering, Service StabiliTrak, and Check Engine Light) should up on the dashboard. Trying to engage the vehicle into drive after parked had a harsh jerk shifting into gear and the accelerator was not working properly (going extremely slower than applied pressure). Mobile mechanic reader coded my vehicle with U0101 “Lost Communication with TCM”. After touching that TCM connection all of the service lights randomly turned back off, and the vehicle drove (temporarily) normal. No repairs were performed due to possible recall concerns.”

“After consulting with a certified technician, I’ve learned this model uses the same 6-speed transmission (6T40) found in several GM vehicles, and that it’s widely known to fail prematurely—many as early as 100K–117K miles. There are dozens of similar consumer complaints filed with NHTSA and discussed online. These are not isolated incidents but part of a consistent pattern of early, costly failures.”

“Engine is known for bad piston rings and a poor emission ventilation system causing extreme engine pressure, blowback, and oil consumption. Engine stalled due to NO oil in it. No oil warning light appeared. Almost ran over two pedestrians as my car would not brake quickly enough as there was no power to any of the systems. And now I have to pay well over $6,000 to repair it? I JUST had my oil changed 5 days ago.”

“Power Steering, Brakes, Turn Signals, Monitor Screen. The Cars steering will lock up and pull to the right hand side and the brakes get mushy. This could be deadly to myself and other motor vehicles. It happens suddenly with out warning and if there is a vehicle in the right hand lane, you will crash into it. I am waiting to take it to the dealer but prior to the steering and electrical, I told them on 10/12/21 oil service about the brakes feeling mushy and they said that’s the way they’re supposed to be. Only other passengers have witnessed the electrical and steering problem happen. At the exact same time the steering goes out the stability trek light flashes on the panel, the media screen goes out and my turn signal (if on) has no audio. I bought the car 3/26/21 @ 44,690 miles. On 10/12/21 I mentioned the brakes and about 2 months after that this electrical/steering problem started happening. It started out as little quirks but has progressively gotten worse. There is not 1 specific thing that seems to trigger the effect, it is variable.”

“Buick issued a Special Coverage Adjustment notice for the passenger prescence sensor Reference Number: N15202352 Letter was sent to all customers, I did not ever receive it. I recently started experiencing error messages with my airbags. Upon taking it to the dealer, the airbag sensor issue is related to the notice listed above. Because I never received the notice, I wasn't on alert for issues. I had to pay the full amount for the fix. My bigger concern is that with the airbag service error going off - if I had been in an accident, the airbag might not have deployed. This known issue should have been a recall and fixed in this car.”
