NEW YORK (AP) — Honda is recalling more than 25,000 cars in the U.S. to replace the rear grab rail brackets, which it says could interfere with the deployment of a side curtain air bag.

The carmaker says no such instances have been reported and that it discovered the faulty design during internal testing.

The company says owners of affected vehicles should go to authorized dealers once they receive notification of the recall. It says notifications will be mailed to customers starting in early December.

The recall affects 25,367 of the Fit LX vehicles, model year 2015-2016.

Owners can also determine if their cars will need repair by going to www.recalls.honda.com or by calling (888) 234-2138.
