July 2021

Chrysler (FCA US, LLC) is recalling certain 2020-2021 Dodge Challenger, Dodge Charger, and Chrysler 300 vehicles. During manufacturing, the windshield may not have been properly bonded to the vehicle, allowing it to detach in a crash. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 212, "Windshield Mounting."

Remedy: Dealers will remove and replace the front windshield urethane sealant, free of charge. Owner notification letters were mailed on August 31, 2021. Owners may contact FCA US LLC customer service at 1-800-853-1403. FCA US LLC's number for this recall is Y47.
