2005 rubicon-2480 miles. Engine indicator light has come on for the 8th time. Dealer checked with digital reader which identifies "small evaporative leak". First time, tightened gas cap, but dealer had turned off the indicator light with the reader. Third occurrence dealer scheduled check of exhaust and clean air system, all tested fine. Last 4 times I disconnected battery until light reset. Dealer has changed hands, and just scheduled for another check, mentioned replacing gas cap. This appears to be a nuisance issue rather than a serious defect. I wish they could fix it once and for all. I am not sure how this new dealer will support the warranty issues. Formerly they were great.
