BACKGROUND

The safety recall portion of this bulletin refers to the welds in the fuel tank for the crossover pipe that are improperly sealed. Clients may notice a strong fuel smell.

There is additionally a product update portion that refers to the thermostat inner seal that detaches and allows the thermostat to be held open. This causes the coolant temperature to increase higher than the expected rate which causes the MIL to come on with DTC P0128 (cooling system malfunction).

California residents only: This safety recall also affects emissions. Have the service consultant give the certificate to the client as proof that both the recall was completed.

 

CLIENT NOTIFICATION

Owners of affected vehicles will be sent a notification of this campaign.

Do an iN VIN status inquiry to make sure the vehicle is shown as eligible.

Failure to repair a vehicle subject to a recall or campaign may subject your dealership to claims or lawsuits from the client or anyone else harmed as a result of such failure. To see if a vehicle in inventory is affected by this safety recall, do a VIN status inquiry before selling it.
