Open the full vehicle complaint log (all categories)Turbo charger has gone out 4 times since I purchased it in April 2021. I have been on the interstate driving and suddenly my car slows down and a message that says “engine power reduced” comes up and my check engine light comes on. This is dangerous as I was on the interstate with 18 wheelers and could’ve been rear ended and badly hurt or killed. My grandchildren could’ve been in the car with me. When this happens the vehicle slows down considerably and does not accelerate properly. I have to drive in the right lane at a much slower speed putting myself and others in danger. Leachman Buick in Bowling Green, KY has repaired the car twice. Campbell Chevrolet in the same city has repaired it twice and it is currently at this dealership due to the engine power situation occurring again. This has caused me severe inconvenience as I have had to drop my car at the dealership several times in the past few weeks and rearrange my schedule as a rental car has not been provided. Campbell Chevrolet repaired the vehicle a few weeks ago and the check engine light and reduce power message was back on within 6 hours of them initially completing the repair. Two weeks or less it was the waste gate actuator solenoid that was replaced but the engine message and check engine light are back on. I am VERY FRUSTRATED at having to jump through hoops regarding this vehicle. I own the Bluegrass Edition model and it is obvious that something serious is wrong with the car and Buick needs to recall the car IMMEDIATELY. It is either a lemon or something else is causing the turbo charger to repeatedly fail. I have taken the car to TWO different dealerships and neither one of them have been able to rectify the issue long term. The vehicle needs to have a TOTAL diagnostic test on EVERYTHING relating to the engine and power system. PLEASE LOOK INTO HAVING THIS VEHICLE RECALLED AS I DO NOT WANT TO LOSE MY LIFE ON THE INTERSTATE DUE TO REDUCED ENGINE POWER AND MY CAR AUTOMATICALLY SLOWING DOWN!!
