Known issues on the 2004 Wrangler. Three recalls are on federal record for this model year: a loss of brake fluid that can lower brake line pressure and increase stopping distance, a tire and loading information label fault that leaves the owner without the correct tire, wheel, and inflation pressure information, and a fuel-pump fuel leak that could cause a fire in the presence of an ignition source. Owners have filed 281 complaints and Jeep has issued 33 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 2004 Wrangler.
