The primary concern of this PE is loss of engine power.stalling may occur at low speed or high speed.at the time of occurrence the average vehicle mileage is 30,000 miles.because these vehicles stall and/or hesitate unpredictably, an increased risk is inherent to these vehicles.if a driver expecting this vehicle to perform as designed, is trying to cross an intersection or merge into traffic when the vehicle stalls it places all motorists within the area at risk.a disabled vehicle is vulnerable to collisions not only within the roadway, but also along side the road as it waits for assistance.
