2003 Jeep Wrangler ProblemsJeep recall on ignition switch due to short-circuit
Jeep issued a recall on the ignition switch because the switch could short-circuit in the presence of water or impurities.
Water can leak near the A-pillar, at the front edge of the driver and passenger side doors. An improved seal is available.
A Check Engine Light may illuminate indicating a "Cylinder #3 Misfire." This normally occurs in hot weather after the vehicle has been driven, parked for ten to twenty minutes, and then restarted. Heat from the exhaust vaporizes fuel inside the #3 fuel injector and causes the misfire. Installing an insulator sleeve normally lowers the temperature enough so the fuel will not vaporize.
