Known issues on the 2023 Gladiator. Four recalls are on federal record for this model year: overheated clutch components that can increase the risk of a fire, a disabled rearview image that reduces the driver's visibility to the rear, a driver frontal air bag that may not deploy in a crash and can increase the risk of injury, and a diesel fuel pump failure that can cause an engine stall and a crash. Owners have filed 68 complaints and Jeep has issued 354 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 2023 Gladiator.
