Chrysler Group LLC is issuing three separate recalls affecting a total of 301,283 vehicles, the National Highway Traffic Safety Administration reported.

The largest of the three recalls involves 295,345 2005-2010 model-year Jeep Grand Cherokee vehicles and 2006-2010 Jeep Commander vehicles because of a potential electrical system problem.

An electrical failure might result in an unintentional shifting of the transfer case into the neutral position, raising the risk of the vehicle rolling away.

This recall covers Jeep Grand Cherokee vehicles manufactured Feb. 11, 2004, through March 9, 2010, as well as Jeep Commander vehicles manufactured Jan. 31, 2005, through March 10, 2010.

To remedy the problem, Chrysler dealers will reflash the final drive controller, which governs the transfer case, with new software. There will be no charge for this service.

This recall is expected to begin in June.

In a separate action, Chrysler is also recalling 5,440 2008-2012 model-year Jeep Wrangler right-hand drive vehicles because they have airbag clockspring assemblies that could experience broken airbag circuits, NHTSA said. As a result, the airbag may not deploy properly during a crash. These vehicles were manufactured Feb. 1, 2007, through Oct. 10, 2011.

Dealers will replace the clockspring and add a steering wheel dust shield, free of charge. The recall is expected to begin this month.

The third recall covers 498 2013 model-year RAM 1500 trucks that might have a faulty windshield defrosting system. The trucks were all manufactured June 25, 2012, through Dec. 12 2012.

In these trucks, the coolant bypass valve might get stuck in a position that doesn’t allow coolant to flow into the heater core. This condition isn’t in compliance with federal safety standards.

Chrysler dealers will replace any faulty coolant valves and provide an updated calibration. There will be no charge for this service.

Vehicle owners affected by these recalls can reach Chrysler at 1-800-247-9753.
