“The electronic engine/gearbox protection switched off the engine while the car is on the move in a highway. The incidence happen twice in 2011 and 2012. Fortunately, I was able to pull over on the shoulder and restart the engine without any adverse incidence. But, the potential for catastrophic injury as a result of sudden loss of engine power in a highway concerns me.”
