The vehicles' engines may be missing valve stem keepers, which can allow the valve to drop into the engine cylinder causing engine damage.
The engines may also have a reversed camshaft cap that can damage the camshaft bearing causing camshaft failure.
Cylinder damage or camshaft failure can cause the engine to stall, increasing the risk of a crash.
What to do
Chrysler will notify owners, and dealers will inspect and repair or replace the affected engine components, as necessary, free of charge.
The recall is expected to begin July 14, 2018.
