Intermittently, the key may not start the car or release from the ignition. If it is excessively worn, replace the key. If the new key doesn't work, replacing the lock cylinder including tumblers should correct this concern.

Most reported 2003 Chrysler Voyager problems
While turning in either direction during low speed parking lot maneuvers, if a creaking, squawking, squeaking, grinding, or groaning sound is heard from the front strut area, locate the front strut dust boot and rotate the dust boot side to side. If the sound is present, applying lubricant to the jounce bumper (bump stop) of both front struts can help with the noise.
A failing head lamp switch can cause the head lamps and/or instrument cluster lighting to flicker or dim. The head lamp switch should have a noticeable click between each position; a "mushy" feel is a strong indication of a failing switch.
Coolant leaks coming from the underbody on vehicles equipped with rear heat/AC are common. The underbody hoses should be inspected as part of regular maintenance. If you drive on roads where salt is prevalent the problem is generally more severe.
A moaning or fog horn sound may be heard while turning at a slow speed. Installing a finned power steering cooler will help alleviate the problem, but it may be necessary to replace the power steering rack.
An oil leak from the oil filter adapter may be evident. Chrysler has made a revised oil filter adapter is available.
If the HVAC (heater) housing is not properly sealed at the bulkhead (firewall), water can leak into the passenger compartment. Foam sealant should be used to seal any gaps and the evaporator drain tube can be modified to prevent further water entry.
Due to a lack of lubrication, the AC compressor can fail. The AC compressor warranty was extended to seven years or 70,000 miles.
If you experience a harsh downshift from fourth to third gear, the transmission control module (TCM) software should be checked and updated if necessary before any other repairs are performed.
