The driver's front airbag can unexpectedly trigger if the wiring harness experiences an electrical short.

Fiat Chrysler Automobiles has launched a recall program for around 209,000 Dodge Grand Caravans from the 2011-2012 model years.Some vehicles may experience a trapped wiring harness between a tab in the steering wheel back cover and the edge of the horn plate, which can chafe the insulation. If left unfixed, the issue can eventually cause a short circuit that inadvertently triggers the airbag.

"Unexpected deployment of the driver's frontal airbag increases the risk of a crash or driver injury," the company warns.

Drivers may have an early indication of potential trouble via the airbag warning light, unintended wiper operation or an inoperable steering wheel switch.

Service technicians will inspect the wiring and replace it if necessary. All affected vehicles will also receive a protective plate to prevent future damage.
