Subaru Baja Acceleration problems by year

The car accelarated for no reason, I was driving about 40 miles per hour on a city street

Tl* the contact owns a 2003 subaru baja. While parking the vehicle, it inadvertently accelerated without warning. The vehicle was taken to the dealer (busam subaru, 6195 dixie hwy, fairfield, oh 45014), but the failure could not be duplicated. The vehicle was not repaired. The manufacturer was notified and informed the contact that they would research the failure. The failure mileage was 79,000.

The throttle pedal looses signal to throttle body causing the car to be unresponsive to any throttle input. A check engine code p2138 also occurs as the throttle looses connection. The problem is most evident in winter months with higher humidity and high temperature fluctuation. Each time the issue has occurred the car has been moving both on city streets and highways resulting in being forced to pull over and restart the car. This issue is dangerous to not only people in the vehicle but hose around it when the car suddenly looses all power.

My vehicle is currently in the shop for the 8th time for the same problem. Each time a different part or parts were replaced and each time the dealer stated that the car was fixed but the same behavior would come back, sometimes within a week or sometimes many months after the repair. There is no rhyme or reason as to when it happens (ie. Nothing leads up to it happening) but basically, it hesitates and sputters or lunges forward while you are accelerating. It's as if the acceleration just drops out but then comes...
