Vehicle description: Electric vehicles. The program logic for the motor electronic control unit (ecu) can mistakenly detect a failure of an electrical current sensor at speeds above 50 mph. If this occurs, the ecu quickly reduces vehicle speed in order to maintain proper feedback control.
Risco: This can result in a sudden loss of power and unexpected deceleration that could cause a rear-end collision.
Solução: Dealers will upgrade the ecu .
