“On september 3rd, sunday 2019, we were driving on highway 60 westbound at the speed of around 65 miles/hour. The engine of my car stopped without any prior warning, and we could move the car 20~30 yards before complete stop. The ontario(california) mercedes benz service center told us the cause of the car failure was a high pressure oil pump related problems. On december 7, 2019, the same car problem occurred. We were driving at the speed of 20 miles/hour on a road in the city of torrence, and the car engine stopped without any warning. …”

The engine was not running after stopping because the tach was at zero. …”
