Accelerator Pedal Sensor problems of the 2018 Chevrolet Malibu

I was driving at approximately 55mph on a highway when the vehicle gave a warning of �engine power is reduced�. My car quickly dropped to 20mph and I was unable accelerate. This happened while there was another vehicle behind me and I was scared I was going to be rear ended. I put my hazard lights on and parked my vehicle. I shut the vehicle off and turned it back on which allowed me to operate the vehicle again but only at a capacity of 40mph. I had the vehicle repaired later that day it needed something with an electronic throttle control and pedal sensor replaced. I also learned that this is an issue that gm is well aware of and feel that they need to recall vehicles affected by this issue. There's no reason a vehicle should be dropping to 20 mph unexpectedly on a highway.

While driving 65 mph car issued warning reduced engine power and check engine light popped on. Car then would not drive faster than 30 mph. Very sudden and with no previous warning this happened. Took to repair shop and after diagnostic was told acceleration pedal sensor was bad. This is not a covered repair and cost $800. This sudden reduction of power is very dangerous and a safety hazard to me and other cars on the road.

While in motion the engine power is reduced then the car slowed to a speed of 20 mph. Upon starting m vehicle a week a later the engine reduction warning came on again. The throttle body was replaced now I'm being told it's the accelerator pedal position sensor . Why should I have to pay for this.
