Known issues on the 2021 Gladiator. Five recalls are on federal record for this model year: two power-train recalls for overheated clutch components that can increase the risk of a fire, a rearview camera that does not display an image and reduces the driver's rear view (crash risk), a gasoline fuel-pump fault that can cause an engine stall, and a diesel fuel-pump failure that can also stall the engine — both raising crash risk. Owners have filed 424 complaints and 682 technical service bulletins are on record for the year.
From a routine service interval to a hard-to-trace wiring fault, it keeps you on the factory procedure and the correct specification for your specific 2021 Gladiator.
