The problem stems from the suspension system. According to Chrysler's recall documents, "a combination of loss of clamp load and inadequate joint engagement" might cause the right front lower control arm to come loose from the steering knuckle. If this happens, the driver might lose directional control of the vehicle, which can increase the risk of a crash.

Chrysler discovered the problem after receiving a field report of this part separation, after which point it launched an investigation to determine what was happening. As of Feb. 18, the automaker says it is not aware of any accidents or injuries related to the issue.
