There are 1 owner-reported engine complaints for the 2021 Buick Envisionin NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
When I push on the accelerator the car hesitates and then surges forward. I took the vehicle to the dealership where they recreated the problem however it was not throwing any codes. After examination they determined that the problem was turbo lag. I was advised to continue driving the car as usual until it throws a code or turbo fails. I believe that the vehicle randomly hesitating could leave you stranded in an intersection with oncoming traffic, and when if surges puts you at risk for a rear end collision. When I asked the service rep what will happen if the turbo fails, she said pull over and call on-star. I'll be traveling through the mountains for the holidays, it worries me that if the turbo fails I could be stuck on the side of the road in winter weather.
