What NHTSA recorded

A deficiency in the routing of the heater duct hose could allow the hose to rest against a terminal post of the accessory relay. Vibration will eventually cause the terminal post to penetrate the hose fabric and short circuit the wire reinforcement and overload the circuit.

Remedy

Dealer will replace the portion of the existing hose that is closest to the accessory relay with an all-rubber hose.
