2021 BUICK ENCORE Complaints

Turbo Charger failed while passing a semi-trailer truck causing a severe lack of power and almost causing a head on collision with on-coming traffic. I had 3 passengers at the time. The problem has been confirmed by a independent service center and I am getting a second opinion from a dealer on 2/3. The check engine light did come on when it happened. There were no symptoms prior to failure. I have since researched the problem and found that Turbo Charger failure is the #1 issue with this make and year.

Went to install a car seat and the place to hook it to is so far Imbedded into the seat I would have to cut the seat to get to it. I need these car seats attached. I am not cutting the seats.
