The defect
Chrysler (FCA US LLC) is recalling certain 2018-2019 RAM 1500 trucks. The rear differential may have been insufficiently filled, possibly resulting in its failure.
The risk
If the rear axle assembly fails, it can cause a loss of drive or the rear wheels may lock up. Either scenario increases the risk of a crash.
