Verbatim reports filed with the United States safety regulator (NHTSA) by owners of this exact model year. Public record.
While driving on the highway at 60 mph, warning on dash came on saying “engine power reduced” and drop down speed to around 25 mph and I could not accelerate more than 25 mph on the highway which could have caused an accident because of the traffic flow behind me. I put a code scanner under the dash and it read code P2138, Throttle pedal position sensor switch.
The contact owns a 2011 Buick Regal. The contact stated that while driving at 30 MPH, the vehicle stalled with the check engine warning light illuminated. The vehicle was able to be restarted. The dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was made aware of the failure. The approximate failure mileage was 140,000.
The cars mileage was altered due to car being wrecked prior and the other car that was used to replace wrecked parts was hidden and vin number was altered. Copart Inc and ICT Sharp Rides are party's involved, I bought car on 12/28/2023 mileage was listed as 132525
