The nut securing the rear axle pinion my loosen because an adhesive patch was not installed during vehicle assembly. If the nut loosens, the axle can lock up with little warning, resulting in a loss of vehicle control and/or a crash. Dealers will install a pinion nut retainer to correct this concern. This is an expansion of a previous recall, NHTSA number 12V474000, Chrysler number M34. The Chrysler recall number for this recall is N08.

The affected vehicles have a spare tire that does not match the specifications listed on the tire placard. If installed, the incorrectly sized spare tire may unexpectedly activate the electronic stability control (ESC) system, altering its effectiveness and increasing the risk of a crash. Dealers will inspect and repair these vehicles as necessary to correct this concern.
