As like many others, both rear exhaust manifold studs sheared off. Ticking and popping sound when you start it, slowly subsides when warmed up. My neighbors enjoy the sound of my old Farmall tractor each morning before work reminding them not to buy a Jeep. So, you need to be half monkey, one quarter snake and one quarter contortionist to reach these bolts. Expensive fix that our friends at Chrysler continue not to acknowledge that there is a ...

If the transmission delays initial gear engagement after being parked overnight or longer, it may be due to a suspect transmission cooler return filter. If the transmission was recently serviced and the part number for the cooler return filter contains an "AB" suffix at the end, a new filter should be installed.
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.
Electrical contacts in the tail lamp housing tend to break or melt, which can cause the brake lights to fail or work intermittently. Complete inspection of the tail light housing and bulbs is recommended before replacing any parts.
A no crank or no start condition may develop due to electronic lockup of the wireless control module (WCM), also referred to as the Sentry Key Remote Entry Module (SKREEM). When this module fails the remote keyless entry system will also not operate. The WCM is commonly replaced to correct this concern.
Leaks at the front and/or rear differential pinion seal and from the transfer case are common. Leakage from the transfer case normally occurs at the case-mating surfaces and require removal of the transfer case to reseal.
Software updates are available to solve various Check Engine Light and warning light related issues.
Due to warped front brake rotors or variations in the thickness of the rotors, brake pulsations may develop. The best method to reduce pulsations is to use an "On the Car" brake lathe (as long as the rotors are suitable for turning). "On the Car" equipment can correct variations (or "runout") in the rotor surfaces because it also corrects variations in other components (e.g. the hub).
The fuel tank may become hard to fill and/or the fuel fill nozzle may shut off repeatedly while fueling. Our technicians tell us that various items including the fuel tank, vapor recirculation tube, fuel fill tube, or EVAP system canister control valve may be at fault. Proper diagnoses will be required to determine the exact cause of this concern.
Updated software will solve an intermittent problem where engine speed is limited to 3,900 RPM while driving.
