DETROIT (AP) — Ford is recalling more than 73,000 full-sized vans in North America to fix a wiring problem that could cause fires and other electrical issues.

The recall covers Ford Transit vans from 2015 through 2017 that have a trailer tow computer module.

Ford says water can enter the module and cause corrosion. That could cause an electrical short and an increased fire risk. Corrosion also can cause unexpected seat belt pretensioner activation, rapid flashing of turn signals, loss of heating and air conditioning controls and other problems.

Ford says fires could happen when the ignition is off so it’s recommending they be parked outdoors until repairs are made.

The company says it knows of two fires in Canadian fleet vehicles that could be related. There’ve been no injuries reported.
