Known issues on the 2020 Gladiator. Six recalls are on federal record for this model year: a driveshaft joint that, run without grease, can overheat and seize and fracture the driveshaft; three separate clutch recalls for overheated clutch components that raise the risk of a fire; front seat belts that may fail to lock in a crash (injury risk); and a rearview camera that holds a lingering image and can distract the driver (crash risk). Owners have filed 623 complaints and Jeep has issued 642 technical service bulletins for the year.

From the recalled driveshaft and clutch components to the seat-belt and rearview-camera systems flagged this year, the data here stays specific to the 2020 Gladiator and its 3.6L V6.
