One problem related to ignition switch has been reported for the 2002 Chrysler Town & Country. The most recently reported issues are listed below.
The key cylinder broke. We just bought the van with 28,000 miles on it. After a few weeks we had a hard time turning the key to get the van to start, sometimes it would take 5 to 10 minutes to be able to turn the key to start the van. We took it back to the Chrysler dealership. They had to replace the inside of the ignition. They said it wasn't a warranty item, so I had to pay $191. 82.
