Driving through town when the car started slamming into gear. Right before, the abs warning light came on and the dash said "stabilitrack disengaged". Car started beeping and lost power. When I was able, pulled over and shut down car. It would not start. Towed it to the dealer and they had difficulty diagnosing. Ultimately replace ip junction box and fp gateway. Same thing happened again 10,000 miles later.
