Jeep intermittently failed to start, turn over, and would shut off while driving down the highway. Then would restart for no apparent reason. Left me miles from home on a -10 degree night in a blizzard. Replaced fuel pump for a cost of $400, had truck towed twice, garage could not find problem.....truck started after unloaded from the tow truck.....finally mechanics put truck in reverse and it cut out.

They found wiring harness behind valve cover was being pinched by engine and broke crankcase sensor wiring harness. Every time they touched it, while truck was running, it would cut out and stop. Another $400. Engineers at Chrysler really messed this one up. Very disappointed in reputation of Jeep being so damaged.
