Under extremely cold conditions, the seat heater control circuit could overheat due to insufficient electrical grounding and burn the seat cushion’s surface. In a worst-case scenario, it could cause a fire.
Dealers will install an additional ground harness on the seat heater control system, replace the entire system or replace the seat if necessary. Whatever the fix, it will be done free of charge.
