Two of Chrysler's most popular vehicles are under government investigations.

The National Highway Traffic Safety Administration is looking into reports that the rear wheels of the Dodge Ram pickup can lock up and possibly cause a crash. The investigation includes the 2009 and 2010 Ram pickups.

The safety agency is also looking into power steering fluid leaks that may cause fires in the 2012 Jeep Grand Cherokee SUV.

No recalls have been issued.
