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.

Temperature blend and recirculation doors commonly fail, which can cause the AC modes not to change or the temperature to be different on the left and right sides. If replacing blend air doors, a recirculation door, a door link, or a sub-assembly housing, new heating, ventilation and AC (HVAC) sub-assemblies are available that improve reliability.

The ABS light can come on, indicating an ABS pump motor circuit fault. This is most likely to occur in warmer areas (above 90° F) and usually after a quick stop, like a refueling. If no faults can be found in the pump motor circuit after proper diagnostics, there is a revised ABS control module which should correct this concern.

Jeep issued an emissions recall in late 2006 to update the powertrain control module (PCM) software on certain 1996 vehicles. As part of the recall, the catalytic converter will also be inspected for damage and replaced as necessary. To see if your vehicle is included in the recall you can visit the Jeep website (owners' section) that allows owners to input their VIN number and check the recalls on their vehicle.
