Description
On your vehicle, the high voltage battery main contactors may overheat, which can result in a contactor that remains open or a contactor that welds closed.
Safety Risk
If your vehicle was previously repaired for this issue under recall 22S41, the remedy may not proactively detect damage to the contactors on your vehicle and needs this new repair. Similarly, if your vehicle was not repaired under recall 22S41, it needs this new repair. Should the contactors weld closed while driving, a powertrain malfunction warning light will be illuminated on the next key cycle, along with a possible no start condition. If the contactors are prevented from closing while driving, a powertrain malfunction warning light will be illuminated, the vehicle will display stop safely now in the instrument panel cluster, and the vehicle will experience an immediate loss of motive power. The vehicle will coast to a stop and all 12V systems including power brakes and steering will remain functional. An immediate loss of motive power increases the risk of a crash.
