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.
Chrysler (FCA US LLC) is recalling certain 2020 Jeep Gladiator vehicles. The rear driveshafts may have been incorrectly assembled without grease in the monoblock joint.
A joint without grease may overheat and seize, possibly causing the driveshaft to fracture, resulting in a sudden loss of drive power. If the driveshaft completely separates from the vehicle it may become a road hazard. Either of these scenarios can increase the risk of a crash.
FCA US will notify owners, and dealers will replace the driveshaft, free of charge. The recall began October 10, 2019. Owners may contact FCA US customer service at 1-800-853-1403. FCA US number for this recall is V95.

The lingering rearview image can distract the driver, increasing the risk of a crash.

The EDR report shows the ABS system was turned off as a result of the sensor. The attached documentation shows an expert reviewed the information and came to the conclusion the failed sensor caused the ABS to be off which in turn caused the brakes to lock. The brakes locking caused a skid which caused the accident. Also to

Steering is very loose, wanders all over the road and is especially noticeable at higher speeds. It’s very exhausting constantly correcting the steering to keep straight on the road. There is a lot of play in the steering box. I’ve taken my jeep to be fixed by the dealership more times than I can count. I’ve had the steering box replaced 3 times with no improvement. This has been a day 1 issue that hasn’t been fixed. It’s especially dangerous in the snow, I had a perfect driving record till I we
