Defect
On certain vehicles equipped with a trailer lighting control module, water may enter the module and connector, and could cause wiring corrosion and damage to the module. This could result in an electrical short to ground, which could cause an uncommanded seat belt pretensioner deployment, a burning smell and/or an increased risk of fire, even when the vehicle is parked and the ignition is off. This may also cause turn signals to flash rapidly as well as cause a loss of the instrument cluster display, heater and air conditioning controls, and multimedia system (radio, screens, SYNC). An electrical short could increase the risk of injury and/or damage to property.
