I was driving on the highway going 50mph and the car stalled and went down to 20mph and it shut off. I was able to get it started again and was only able to go 20mph all the way home. My car insurance app has engine alerts and it stated it is the throttle/pedal position sensor/switch 'd'/'E' voltage correlation. The the alert stated it was urgent because it decreases the engine performance and the engine may enter limp home mode. I was very lucky no cars where behind me when this happened.

The contact owns a 2005 Buick Lacrosse. While driving between 55-60 mph on normal road conditions, a low power response occurred when the accelerator pedal was depressed. In addition, the brakes were not performing properly and the stopping distance increased. There were no warning indicators illuminated on the instrument panel. The failure occurred each time the vehicle is in use. The vehicle was taken to the authorized dealer for diagnostic testing and the front brake pads were replaced. On a separate occasion, the vehicle was taken to an independent mechanic for identical failures and the tie rod and wheel hub were replaced, and the brake drums were resurfaced. However, the failures still persist. The failure mileage was 52,000. The VIN and current mileage were unknown.
