The recall affects 2010 model year Wranglers with automatic transmissions.
The problem is with a skid plate that's located close to the vehicle's catalytic converter that can trap debris. Catalytic converters get extremely hot and that heat can ignite the debris and cause a fire.
Chrysler has acknowledged at least 14 reports of fires so far.
Wranglers that were built in subsequent model years don't have this problem, because Chrysler switched to lighter-weight skid bars, which don't trap debris in the same way.
To fix the problem, Wrangler owners will be asked to bring their vehicles to a jeep dealership to have the skid plate replaced with skid bars.
