Defect
In the generator motor of the electric continuously variable transmission, the crimp securing the magnet retention plate on the motor shaft is improperly formed. Extended idling or high-load driving causes the plate to wear until it contacts the coil, resulting in a short circuit. This causes a warning light to illuminate and, in the worst case, the hybrid system may shut down, rendering the vehicle inoperable.
Corrective action
Replace the electric continuously variable transmission with a conforming unit.
