A discovery of malfunctioning head-restraint devices in several makes and models of Chrysler Group LLC vehicles has resulted in the company issues a recall for their products this week.

According to a statement released by Chrysler Group Wednesday via CNN, the defective microcontrollers, which are used to prevent neck injuries and move head restraints forward in the event of a rear-impact crash, have been proving faulty. The company reported it is unaware of any related injuries or accidents as a result of the error. 

"The potentially faulty microcontrollers were installed in a supplied component," the group said in a statement. "They entered the supply chain after the 2011 earthquake and tsunami in Japan caused a worldwide microcontroller shortage."

A reported 442,000 Chrysler vehicle owners in the U.S. are affected by the recall. Ten-thousand in Mexico, 25,000 in Canada and 12,000 in unidentified locations are also affected. 

Vehicles currently being recalled by Chrysler for malfunctioning microcontrollers include:

  • - 2011-2013 Chrysler Sebrings
  • - 2011-2013 Chrysler 200s
  • - 2011-2013 Dodge Avenger (mid-size cars)
  • - 2011-2012 Dodge Nitro SUVs
  • - 2011-2013 Jeep Liberty SUVs

Vehicle owners affected by the recall will have the part replaced and their system software upgraded at no cost as needed. Questions regarding the recall can be directed to 800-853-1403.

Just last month, Chrysler controversially refused to recall 2.7 million of its vehicles for complaints regarding plastic gas tanks positioned near rear axles. The company changed its tune Tuesday, confirming the company would conduct a voluntary campaign to inspect and provide proper upgrades to affected vehicles.
