Known issues on the 2003 Grand Cherokee. Six recalls are on federal record for this model year: a hydraulic service-brake fault where a loss of brake fluid can lower brake line pressure and increase stopping distance, a headlight defect where missing amber reflectors leave the vehicle poorly illuminated and can lead to a crash, a second headlight problem where decreased lighting visibility may result in a crash, a front-seat heater that can overheat and cause a fire or injury, an exterior-lighting fault where decreased lighting visibility may result in a crash, and a fuel-pump leak that could cause a fire in the presence of an ignition source. Owners have filed 889 complaints and Jeep has issued 70 technical service bulletins for the year. This manual carries the factory diagnostic and repair procedures behind each of those systems.
From a routine service interval to a control-module reflash or a hard-to-trace wiring fault, it keeps you on the OEM procedure and the correct specification for your specific 2003 Grand Cherokee.
