Known issues on the 2021 Wrangler. Eleven recalls are on federal record for this model year: a traction battery that can catch fire and cause injury, overheated clutch components that can lead to a fire (two separate recalls), a rearview camera that fails to display an image and reduces the driver's rear view, an engine shutdown that can cause a loss of drive power, a fuel leak that can ignite in the presence of an ignition source, a second traction-battery fire that can occur while parked or driving, an inoperative windshield defrosting and defogging system that can reduce visibility, a seat belt pretensioner failure that may not properly restrain an occupant in a crash, a gasoline fuel pump fault that can cause an engine stall, and a diesel fuel pump failure that can result in an engine stall. Owners have filed 1,436 complaints and Jeep has issued 1,016 technical service bulletins for the year.
Whether it is a routine service interval or a hard-to-trace fault, everything stays specific to your 2021 Wrangler — the right engine, trim, and year.
