This morning I had a very weird experience. After driving for 80 miles, I tried to pass another car, the transmission downshifted, but then i experience a sudden loss of power for 3-5 seconds and I noticed the D symbol on a dashboard was blinking. After those 5 seconds everything was back to normal and I continued driving for another 120 miles. The car doesn't display any messages and it feels perfectly fine. Anyone has any idea what might have happened? The car is 2018 gas 237hp with automatic transmission and has 9500 miles.
