The vehicle suddenly loss power while I was driving on a busy interstate. I was almost rear-ended by the vehicle behind me. I had to coast my vehicle to the shoulder of the road crossing lanes of traffic without power! It was terrifying. I could have been wrecked our worse! The check engine lights flashed on saying: "Service Electronic Throttle Control" and "Start / Stop unavailable". I took the car to get it checked out and I was told that this is a common problem currently under recall for the 2018 models, but not my 2020. The mechanic says the scanner code is P008A, a fuel system problem which is likely a faulty fuel pump.
