One problem related to roof and pillar has been reported for the 1997 Jeep Wrangler. The most recently reported issues are listed below.
The top was bought last year. Stored, hard top was removed, soft top was put on, and plastic pieces were screwed on the top over windshield and driver/passenger doors. When the wind stresses against the plastic the fiber plastic material rips open and comes apart, 8 inch tear in both sides.
