2020 Gladiator JT rear driveshaft recall, NHTSA campaign 19V-636

NHTSA campaign 19V-636 was filed by FCA US LLC for certain 2020 Jeep Gladiator vehicles. It falls under the power train, driveline and driveshaft category, and the filing describes a problem with the rear driveshaft. On the platforms this site covers, that is the Gladiator JT, model year 2020, the first year of the truck.

The remedy is a straight replacement. FCA US will notify owners, and dealers will replace the driveshaft free of charge. The filing notes the recall began in October 2019, so most trucks in the affected range should have been repaired long ago. The reason to write it up now is that first-year Gladiators are well into the used market, and a recall that was never completed follows the VIN, not the owner.

The campaign is not stop-drive. But a driveshaft is a component that, if it lets go, can do serious damage on its way out. On a truck that gets used the way a Gladiator does, with the rear end loaded and the driveline working hard in low range, the practical advice is to confirm status and get any open repair done before the next trip.

The check is simple. Run the VIN through the manufacturer's recall lookup, then confirm on the NHTSA recall page. If the campaign shows as open, contact a Jeep dealer and quote 19V-636. The dealer will see the open recall against the VIN and can order the driveshaft. Ask about parts availability when you book, because an older campaign can mean the part is not sitting on the shelf.

If you bought the truck used, ask the seller or the previous dealer for any recall work orders. Absence of paperwork does not mean the work was not done, because the VIN check is authoritative, but a work order is a useful thing to have in the glovebox. Recall repairs are free regardless of ownership history or whether the factory warranty has expired.

Owners who have lifted or otherwise modified the driveline should mention it. Lift kits change driveshaft angles on the JT, and a technician doing a recall replacement will want to know what they are looking at. The recall covers the original driveshaft defect, not wear caused by an angle change, so an honest description at the counter avoids a dispute later.

While you are underneath the truck, this is a reasonable time to look over the driveline generally. Check for play at the universal joints, look for grease thrown from a boot, and listen for a clunk on and off the throttle. None of that substitutes for the recall, but it tells you whether something else needs attention on the same visit.

The JT platform runs from 2020 to 2026 and this campaign covers the first model year only. Later trucks are outside 19V-636. Any JT owner should still run a VIN check once a season, because it catches any other open campaign at the same time.
