Risk: If the rear lower control arm fractures it may result in a change in ride height, loss of rear end stability, and reduced braking capabilities, increasing the risk of a crash.
Remedy: Chrysler will notify owners, and dealers will inspect and if necessary replace the lower control arms, free of charge.
