Chrysler Group issued a rare recall Sunday for 2013 Dodge Challengers equipped with V-6 engines, and took the even more unusual step of telling owners not to drive them.
The recall affects only 4,459 Challengers because of a wire harness that can overheat and lead to fires. Chrysler says it is a aware of seven incidents, none of which caused injuries.
Spokesman Eric Mayne says the problem is due to a single batch of misconfigured electrical components. He refused to specify the particular part, not necessarily the wiring harness, at the heart of the problem. In any case, workers tried to reconfigure the parts, but the result was harnesses that can overheat and catch fire.
The recall applies only to cars made over the two months leading up to Jan. 24. About 2,500 of them are in the hands of owners. The rest are on dealers' lots.
Chrysler says it is trying to reach owners by phone and mail to tell them to park their cars until they can be repaired. In addition, it's telling them to make sure their cars aren't parked in garages or near other structures just in case they catch on fire. The automaker will provide a free loaner car.
The Challenger is a performance car that is often ordered with a big V-8 engine, but those aren't affected by the recall.
