The National Highway Traffic Safety Administration is investigating 2009 and 2010 Ram pickups because the rear wheels may lock up, according to The Washington Post. The investigation affects up to 230,000 Ram vehicles.
No recall has been announced yet, and Chrysler said it is cooperating with the government, the Post reported. NHTSA opened the Ram investigation after receiving a dozen complaints about locking rear wheels, the Post reported. Some sources are reporting the issue may involve a pinion nut coming loose in the rear differential that can cause the rear driveshaft to lock up. No specific Ram trims were mentioned.
