Jeep Gladiator JT problems to check before you buy

  1. Run the VIN for recalls firstGladiators have had recalls for rear driveshafts (19V-636), manual clutches (20V-124, 21V-028, 23V-116 and 24V-572), EcoDiesel fuel pumps (22V-767, 23V-263), instrument clusters (24V-652) and, in June 2026, power-steering pump wiring that can start a fire with the truck parked (26V-363). Confirm each one is done.
  2. Manual trucks: ask about the clutchThe clutch pressure plate can overheat and fracture. FCA first issued software, then replaced clutch assemblies under 23V-116, and some 2021 trucks needed a second software fix under 24V-572. Ask for dealer paperwork, not a shrug.
  3. Drive it at 50–65 mph over a bumpGladiators can shimmy or wobble after a highway expansion joint, as JLs can. Owners on JeepGladiatorForum report dealers replacing the steering damper or the steering box. Any wobble means the front end needs inspecting before you hand over money.
  4. Diesel? Check the fuel pump historyEcoDiesels were recalled twice for high-pressure fuel pumps that can fail and stall the engine. Look for the recall paperwork, ask about fuel-filter changes and look at the oil level. Diesel trucks are also about 300 lb heavier, so payload is lower.
  5. Look under the bed and behind the bumpersCheck the frame, bed mounts and spare-tire carrier for damage from off-road use. Check the rock rails and skids for dents that hint at hard use, and the hitch area for signs of heavy towing.
  6. Know which axle and gearing you're buyingSport and Overland trucks came with 3.73 gears and a narrower 62.9 in track. The Max Tow package, Rubicon and Mojave have 4.10 gears and wider track. Rubicons add front and rear lockers and the 4:1 transfer case. Check the window sticker or build sheet.
  7. Lifted trucks: inspect the steering and track-bar mountsBig tires and lifts load the steering box, track bars and their mounts. Look for elongated holes, fresh paint on welds, and torque marks that have moved. Ask what was done to correct the track-bar geometry.
  8. Hardtop and doorsMake sure the Freedom panels, hardtop seals and removable doors come with the truck and fit without leaking. Water stains on the carpet usually mean worn seals or poorly fitted panels.

Driveshafts: recall check and U-joint serviceVibration under acceleration, a clunk on take-off, or a squeak from the driveshafts. Recall 19V-636 covered 2020 Gladiators built between December 15, 2018 and June 25, 2019 whose rear driveshaft monoblock joint may have been assembled without grease. Wikipedia counts about 3,427 trucks.2 / 5≈ 1–2 hoursRecall replacement free; U-joints or a CV shaft otherwise
Re-spring the rear for a real loadThe rear sags or bottoms out once a camper shell, bed rack, rooftop tent or trailer is added.

Owner questions about Jeep Gladiator JT reliability

Is the long wheelbase a problem off-road?

Sometimes. Breakover is 18.4° on a Sport and 20.3° on a Rubicon, and the turning circle is 44.5–45 ft, so tight trails take more shuffling than in a Wrangler. Rock sliders matter more on a Gladiator than on a Wrangler.
