2016 Buick Verano Complaints

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.

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 transmissio...

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.

The paint has severely faded, chipping, and it is not from environmental factors- I have less than 30,000 miles on a 2016 Buick Verano. There are multiple websites confirming other consumers have had the same issues with their 2015/2016 Buick Verano.
