    Driving on the highway car was starting to loose speed, lights on dash starting to flash I was able to pull off on the side of the road, car stalled and steering wheel locked up. After several minutes it turned on and drove away fine. This is not the first time this has happened. Did oil consumption test several times and stated I’m in the safe zone. This is a severe safety issue but no recalls for my VIN. I saw lots of cars have this same issue with engine stalling.
