Chrysler Group is recalling 291,703 vehicles in the US to check for a faulty ignition switch which could inadvertently turn off the engine.

In the affected vehicles, the ignition key may not return to the ON position after being rotated to START position, instead sticking between the two positions. Potentially, while the vehicle is being driven, the ignition may inadvertently move through the RUN position to the ACCESSORY or OFF ignition position, turning off the engine

The cars are 2008 Chrysler 300s made between 31 May, 2007 to 12 May, 2008, Dodge Magnums made from 23 May, 2007 to 12 May, 2008, Dodge Chargers made between 24 May, 2007 to 12 May, 2008, Jeep Commanders made between 3 April, 2007 to 12 May, 2008 and Jeep Grand Cherokees made between 21 March, 2007 and 12 May, 2008.

If the ignition stays between START and ON positions it could cause loss of certain electrical functions, the NHTSA said. If the ignition key inadvertently moves into the OFF or ACCESSORY position, the engine will turn off, which will then depower various key safety systems including but not limited to air bags, power steering, and power braking. Loss of functionality of these systems may increase the risk of crash and/or increase the risk of injury in the event of a crash.

The remedy for this recall campaign is still under development, NHTSA added.
