One problem related to radiator hose has been reported for the 2003 Chrysler Town & Country. The most recently reported issues are listed below.
11/2/11 while parked & running idle, van shuts off and all power is lost. After 15 min the van finally starts. However, after driving 200 feet it loses power again. Road side service jumps the battery, all seems to operate normally. Over the next couple of days the same thing happens many times. 11/8/11 a new battery is installed. (starter & alternator pass tests) new battery van still losses power when running idle parked/in operation(at traffic light). Frequency increases and eventually van loses power/ stalls while driving. At times van is able to start up right away, other times it has to sit for a few min. Some warning or indication that system may fail, van may shutter a bit/rpm gage needle fluctuates wildly. Another new glitch, the door power locks and power door locks alarm. Power door locks stop working 2/12. Fuse is replaced. Problem is fixed temp, locks stop working days later. Fuse is removed and reseated. Power locks work but only for a short period of time. This process is repeated several times. Battery cable is taken off in hopes of resetting power module but upon reconnecting cable, battery has no life. End result, battery is replaced, tests are run again on starter/alternator, they pass. Van runs okay for about a day, locks stop working again. Next door open alarm and interior lights are set off repeatedly. As of today all issues are still present but seem to come and go.
