Chrysler Group LLC is recalling about 40,000 Chrysler, Dodge and Jeep models from the 2010 year. The vehicles may have a defective ignition switch that would allow the key to be removed prior to placing the shifter in the "park" position. This could lead to unintended vehicle movement.

The affected models are:

• 2010 CHRYSLER / 300
• 2010 DODGE / CHALLENGER
• 2010 DODGE / CHARGER
• 2010 DODGE / RAM
• 2010 JEEP / COMMANDER
• 2010 JEEP / GRAND CHEROKEE

Dealers will inspect the ignition module and replace defective units free of charge when the recall begins in July 2010.

Owners may contact Chrysler at 1-800-853-1403.

Consumers may contact the National Highway Traffic Safety Administration (NHTSA) at 1-888-327-4236 (TTY: 1-800-424-9153) or at www.safercar.gov.
