The official notice
Defect
On certain vehicles, due to software programming within the engine control unit, the operating threshold of the radiator fan used to cool the fuel temperature is not set low enough for the fan to operate at an appropriate temperature when using winter blend fuels. This could result in the fuel vaporizing prematurely under certain outside temperatures and driving conditions, which could cause a decrease in fuel pressure. If this occurs, the engine may stall in certain circumstances while the vehicle is in motion, including low speed, stop-and-go traffic, or at a stop and may not be able to be restarted immediately, which could increase the risk of a crash causing injury and/or property damage.
Safety Risk
No risk description available.
Remedy
Dealers will reprogram the engine control unit with new software.
