Defect
On certain hybrid vehicles, if the vehicle continues to be operated for a prolonged period of time following a cooling system malfunction that causes the vehicle to overheat, the hybrid powertrain control module will shut off the engine, as designed, to prevent damage. This could cause the engine to shut off while the vehicle is in motion, which would result in a loss of motive power which could increase the risk of a crash causing injury and/or damage to property.
Safety Risk
No risk description available.
Remedy
Dealers will reprogram the software for the hybrid control module, automatic transmission control unit and inverter to allow the engine to continue operating at reduced power in the event of a cooling system malfunction.
