II. BACKGROUND
Some of the subject vehicles may be equipped with an engine block that was manufactured incorrectly. This issue may cause coolant to leak internally and/or externally during normal engine operation. This can lead to engine noise, engine smoke, warning lights/malfunction indicator illumination, an audible chime sounding, and/or, in some cases, engine overheating and possible internal mechanical engine damage. If this occurs in a conventional gasoline vehicle, it is possible the vehicle could stall while driving at higher speeds without prior warning, increasing the risk of a crash. For both hybrid and conventional gasoline vehicles, the mechanical engine damage could cause engine oil to leak, which, in the presence of an ignition source, can lead to an increased risk of fire.
NOTE: If the engine stalls in a hybrid vehicle, the vehicle will enter a fail safe driving mode, allowing the driver to operate the vehicle at reduced power for certain distances to maneuver the vehicle to a safe location.
III. IDENTIFICATION OF AFFECTED VEHICLES
• Check the TIS Vehicle Inquiry System to confirm the VIN is involved in this Safety Recall, and that it has not already been completed prior to dealer shipment or by another dealer.
• TMS warranty will not reimburse dealers for repairs completed on vehicles that are not affected or were completed by another dealer.
