If the transmission was recently serviced and the part number for the cooler return filter contains an "AB" suffix at the end, a new filter should be installed.

The throttle body may malfunction in very cold climates causing symptoms at engine start up. A throttle body causing problems will require replacement.
If a Check Engine Light illuminates indicating leak detection pump (LDP) failure, the cause is often pinched or disconnected vacuum lines to the pump. Vacuum lines should be inspected before replacing the leak detection pump. Contamination (carbon or debris) in the pump can cause failure and any hoses should be cleared before a new pump is installed.
The drip rail door seal may become torn form contact with the lower A-piller. A revised secondary door seal is available to correct this concern. This is not a recall but a technical service bulletin (TSB) which means the failed part will be replaced at the customers expense once the warranty has expired.
On the 3.7L V6 and 4.7L V8 the camshaft position sensor may fail and cause the engine to crank but not start or it can cause intermittent stalling. A failed camshaft sensor will require replacement.
