I dont think the problem is with the Jeep but with the owners
we have had our '03 from day 1 and take very good care of it
it has NEVER had any thing go out that was not normal wear
yeah brakes at 60K+ ,normal, dead batt, after 4+ years ,normal
shocks/struts after 30K ,premature but they still go out around 36-40K
tires ,put the right ones on from day 1 and they will be fine
we have not even had a light bulb burn out and the thing is 5+ years old
we do have a hole in the driver side CV boot ,RTV fix 6 moths ago still holding
but that happened off road so I call that normal or expected
Take care of them and they will last just fine
