Known issues on the 2003 Wrangler. Three recalls are on federal record for this model year: a hydraulic brake-system fluid loss that decreases brake line pressure and increases stopping distance, an equipment defect that could cause injury by striking persons outside the vehicle, and a fuel-system leak that could result in a fire in the presence of an ignition source. Owners have filed 130 complaints and Jeep has issued 40 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 hard-to-trace wiring fault, it keeps you on the OEM procedure and the correct specification for your specific 2003 Wrangler.
