The largest - and potentially the most dangerous - recall involves 469,072 Jeep SUVs that may be at risk to roll away when parked. According to a notice posted on the National Highway Traffic Safety Administration's website, an electrical failure in the transfer case actuator encoder may result in an unintentional shift into neutral during the vehicle startup sequence.
The recall affects 2006-10 Jeep Commanders and 2005-10 Jeep Grand Cherokees, including 295,000 SUVs in the U.S.
To address the problem, dealers will reflash the final drive controller that governs the transfer case. The recall is expected to begin in June.
Twenty-six crashes and two injuries stemming from the rollaway issue have been reported, Chrysler spokesman Eric Mayne says.
The second recall pertains to 5,440 right-hand-drive Jeep Wranglers from the 2008 to 2012 model years. These vehicles - used almost exclusively for mail delivery in rural U.S. areas - need to have a dust shield installed to prevent the buildup of dirt in the airbag clockspring wiring assembly, which can keep the driver's front airbag from deploying properly in the event of a crash.
This recall - which is set to begin this month - was actually originally announced back in 2011, but at that time Chrysler and the NHTSA didn't yet have a solution for the issue.
The final recall seeks to remedy a cooling system problem in 498 Ram 1500 pickups from the 2013 model year. In these vehicles, the coolant bypass valve is at risk to stick in a position that prevents coolant from flowing to the heater core, preventing the defroster from working properly.
Chrysler will notify owners of the recall in June, at which time dealers will replace the faulty cooling valve and perform a software update.
