Unknown issues w/ sensors and wiring lead to turbocharger failure. This led to spontaneous acceleration issues on the highway. Less than a year after the warranty covered the replacement of the turbocharger (less than 60k miles on the car) the turbocharger again failed (64k miles on car).
The contact owns a 2020 Buick Encore. The contact stated that while driving at an undisclosed speed, the brake pedal and accelerator pedal became extremely hot to the touch. The contact became aware that the silver heat shield was missing. Additionally, the contact stated that there was electrical activity or electricity coming from the area. No warning lights were illuminated. The vehicle was taken to a local dealer; however, the dealer was unable to determine the cause of the failure. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 77,213.
I was driving on the interstate and the vehicle was in cruise control. It acted as it was accelerating and then the cruise control quit and I lost speed. I regained speed and then it lurched again; the cruise control again went off. When I applied the brake to pull to the side of the road, the engine started to throttle up and accelerate, I had to brake harder to come to a full stop.
