“The contact owns a 2021 Jeep Compass. The contact stated that while driving 75 MPH, the vehicle unexpectedly stalled in the middle of the highway. The vehicle lost power, but was able to be restarted, and the vehicle drove in LIMP Mode to the dealer. The "D" on the instrument panel was flashing during failure, and there was an electrical odor inside the vehicle. The failure was a recurring failure.
