Strong fuel smell that comes and goes. Dealership replaced fuel injection related parts after finding a leak. Problem is still present.
We drove an hour then sat in the car while it was on for about 30 minutes. The gas tank was 14% full. We started driving again down a bit of a hill & got to a stop light. The car started beeping & said “engine off! Switch to N then start engine” We turned the car off and back on & it started working.
