Ford is issuing a safety recall for approximately 6,500 2011-2013 Ford F-Series Super Duty ambulance vehicles and 2014-2015 Ford F-Series Super Duty ambulance and emergency vehicles equipped with 6.7-liter diesel engines in North America (actual 6,472). The exhaust gas temperature sensors may not function properly, causing the vehicle to incorrectly identify a high temperature condition.

Ford is not aware of any accidents or injuries attributed to this condition, and that includes patients riding in the ambulance vehicles. The company is taking this action because of the unique nature of ambulance and emergency vehicles.

Affected vehicles were built at Kentucky Truck Plant, Feb. 22, 2010 to Feb. 1, 2015.

There are 6,322 vehicles in the United States, 96 in Canada and 54 in Mexico.

Dealers will update the software on affected vehicles at no cost to the customer.
