Affected is the 2005 Dodge Ram 1500 built between January 2004 and August 2005. The problem stems from a pinion nut that can loosen, leading to the possibility of the rear axle seizing. The driveshaft may also detach, leading to a loss of power and increasing the risk of a crash.
The National Highway Traffic Safety Administration launched an investigation into these pickup trucks in June of this year after receiving 15 complaints. Seven of those incidents happened at speeds above 50 mph, with no noise or indication beforehand that anything was wrong.
Chrysler dealers will install a retention feature to the pinion nut to make sure it cannot work itself loose.
