Ford Motor Co. recalled 33,228 new vehicles during Christmas week in North America for possible burn risk and power loss, including vehicles sometimes used as hotel and airport shuttles and ambulances.

The 2021 Ford E-Series vans with a 7.3-liter engine may have insulation under the engine cover that fails to extend over the whole area as intended, allowing heat from the engine to make the engine cover too hot. The situation may be exacerbated in vans modified with “stationary elevated idle control or battery charge protect.”

Direct contact with the engine cover in the passenger compartment may cause burns to the driver or front passenger, Ford said.

Ford said in a news release it is unaware of any accidents or injuries related to this condition.
