I had the same problem. @1770 km the engine didn't start while in the start-stop mode the car was @ the junction. After my foot get off of the brake nothing happened. Had to put it in P, then press the Start/Stop engine for a few seconds. Then the EPC error showed up. Turned the car off and on and it worked Ok for a while ...
The dealer had found nothing. Will keep bugging them 🤢
