“This car now has a reported second failure of an electrical part that controls the correct operation of this vehicle and it's engine. The failure rate on this item now exceeds 33%, which is not an acceptable rate for a critical engine electrical item! The failure noted here is very dangerous for the live of the people in this vehicle, as it may create an inoperable vehicle in a critical situation. At my age, I do require a safe and operable vehicle!!”
