The power door lock switch can short-circuit internally causing a battery drain and/or the key operated accessories to function even though the key is off. If the power door lock switch is diagnosed to be the cause, replacement of the switch should fix the concern.
The brake pedal may not return to its fully released position causing the brake lights to stay on. If no brake pedal return spring is in stalled there is a spring kit available. If the brake pedal return spring does not correct the problem the actuator piston should be replaced.
The transmission has numerous problems; symptoms can range from shuddering to completely dying. The majority of the TSBs (service bulletins) require an overhaul of the transmission. Updated internal parts are available.
Poor electrical connections at the input or output speed sensors may cause the cruise control to become intermittently inoperative.
The shifter may become locked in neutral or reverse. A stronger reverse detent spring is available to correct this condition.
A squeak noise when shifting out of gear may develop where the shift cable attaches to the gear shift lever. Our technicians tell us the shifter assembly must be replaced to correct this condition.
A poor connection at the rear load leveling or air suspension relay can cause the rear of the vehicle to sag intermittently. Our technicians tell us that the connector can be secured at the relay using a tie strap.
Improper fuel pressure or fuel pressure fluctuation may be cause by a faulty fuel pump module.
A high pitched whistling noise from the engine may be caused by the idle air control motor. Our technicians tell us there is a revised IAC motor to correct this condition.
A loud snapping noise may be heard from the exhaust after the engine has been shut off. Replacing the exhaust pipe may be necessary to correct this issue.

Child seat tether anchors are available from Chrysler and can improve the performance of child restraints. Each tether kit has all the necessary parts and detailed instructions according to our technicians.
Jeep issued a recall on some ABS equipped vehicles because seals inside the master cylinder fail. When the seals fail, a loss of pressure is detected causing the ABS hydraulic pump to cycle on more frequently or run continuously. This will lead to premature failure in the hydraulic pump. There is a lifetime warranty on the seals and the hydraulic pump motor. Normal braking will still work but brake pedal effort may increase.
Excessive smoke from the exhaust, lack of power, and a grinding or scraping noise from the turbocharger can indicate turbo failures. The most frequent cause of turbocharger failure is a lack of frequent oil changes.
