All 3 of the engine stalls have occurred on the highway as I have reduced speed in preparation to enter a lower speed limit zone or in preparation to stop at an intersection. The loss of power during these stalls makes breaking and turning extremely difficult. In addition, I'm forced to come to a stop in the middle of the road in order to restart the engine. This is a very dangerous situation.”
