Share Download Print Statement: Active Head-Restraint System July 3, 2013 , Auburn Hills, Mich. - Chrysler Group LLC will recall approximately 490,000 cars and utility vehicles worldwide to address active head-restraint function. Active head restraints are designed to mitigate neck injuries by automatically moving forward during certain rear-impact collisions. Potentially faulty microcontrollers in some vehicles may prevent the systems from functioning properly. Chrysler Group is unaware of any related injuries or accidents. Airbags and shoulder-restraint systems are not affected. The potentially faulty microcontrollers were installed in a supplied component. They entered the supply chain after the 2011 earthquake and tsunami in Japan caused a worldwide microcontroller shortage. Chrysler Group will replace the component or upgrade system software as needed, at no cost to its customers. Affected are the 2011-2013 Chrysler Sebring, 200 and Dodge Avenger midsize cars; 2011-2013 Jeep Liberty SUVs and 2011-2012 Dodge Nitro SUVs. The campaign involves approximately 442,000 vehicles in the U.S.; 25,000 in Canada; 10,000 in Mexico; and 12,000 outside the NAFTA region. Chrysler Group will notify affected customers. Questions or concerns can be addressed by calling 1-800-853-1403.
