Chrysler has issued a safety recall for one of its most popular Jeep SUV models, because of an issue with headrests. Over 121,300 Jeep vehicles are affected by the recall, according to the National Highway Traffic Safety Administration.

Faulty second-row headrests may not lock in the upright position, increasing the risk of injury to passengers, according to federal safety regulators.

Chrysler, which is owned by the same company as Jeep (Stellantis), reported the recall to the NHTSA on July 17.
