Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering powertrain on this vehicle — documented repair instructions, service campaigns, or warranty extensions sent to dealers. A TSB isn't a recall (it's not a free safety remedy), but it's the manufacturer acknowledging the issue and how to fix it.

The failure pattern owners describe
The clutch recall (NHTSA 23V116000) dominates the cluster. Owners report clutch failure as early as 1,300 miles, with smoke and burning smell, but the remedy parts haven't been available—dealerships have told owners to wait months or informed them the fix isn't ready. One owner's vehicle failed again at 49,500 miles even after the recall repair was supposed to be completed. Another waited four months for parts that never arrived and paid an independent shop instead.
The fuel pump recall (Y78/21V-880) has created a separate nightmare. One owner's HPFP failed while cornering, causing total power loss on a mountain road in remote New Mexico. The dealer said it was safe to keep driving until a remedy was available, which took two months—and when the vehicle returned, metal shavings contaminated the fuel system, leaving it inoperable. Another owner's fuel pump failed after being replaced once before under the same recall.
Beyond the recalls, owners describe transmission shifting failures (won't go into or out of neutral or park), rear locker control malfunction (engages and won't respond to buttons), camshaft failures starting after warranty expires, transmission seal leaks, rear differential failure with cascade damage to axles and brakes, and a steering wobble condition. The pattern across multiple owners is one repair spawning another problem.

Failure modes owners describe
High-Pressure Fuel Pump (HPFP) Failure
HPFP failure causes complete loss of engine and transmission power with difficult steering. Owner reports the vehicle was under active recall Y78 / NHTSA 21V-880 with no remedy available; dealership told owner it was safe to continue driving. Failure occurred in remote area. After initial repair, metal shavings remained in fuel system, leaving vehicle inoperable. Second complaint involves a fuel pump (reported as already replaced once under recall) that failed again and was diagnosed as defective; dealership drained fuel, replaced bottom fuel lines and fuel pump multiple times before confirming fuel pump defect.
When: Complaint 1: while entering downhill curve; Complaint 2: fuel pump had been replaced once before under recall; failure occurred after ~80 miles of prior driving
Symptoms owners cite: Complete loss of power to engine and transmission; Difficult steering; Unrecognizable warning light that flashed but did not remain on; Check engine light after initial repair; Metal shavings in fuel system; Vehicle would not start
Codes mentioned: Check engine light
Repairs/costs cited: Complaint 1: HPFP replacement; took 2 months for parts/remedy; metal shavings still present after repair. Complaint 2: fuel tank drain, replacement of bottom fuel lines, fuel pump replacement (multiple times); fuel pump confirmed defective.
Recalls/TSBs owners mention: Complaint 1: NHTSA Recall Y78 / 21V-880 (remedy not yet available when failure occurred); took 2 months to complete initial repair; vehicle still inoperable with metal shavings in fuel system.

Failures occur at low mileage (1,300 miles to 49,500 miles) with symptoms including smoke from clutch, inability to accelerate above 40 mph, inability to shift out of neutral, and burning smell. One owner reports clutch failure at 4,400 miles with flywheel hot spots. Recall parts are not available; repairs are delayed months or not completed. One vehicle failed again after recall repair was supposedly completed.
When: Complaint 4: ~1,300 miles; Complaint 5: ~49,500 miles (after recall repair completed); Complaint 6: ~24,137 miles; Complaint 12: 4,400 miles; Complaint 14: persistent issue over a year
Symptoms owners cite: Smoke coming from clutch; Burning smell from clutch; Failure to accelerate over 40 mph; Service Transmission warning light illuminated; Unable to shift out of neutral; Inability to shift vehicle

Complaint 5: dealer diagnosed clutch failure but did not repair; waiting for warranty determination. Complaint 6: clutch assembly replacement needed but not repaired (parts not available). Complaint 12: clutch burned out with flywheel hot spots; vehicle in dealer for repair.
Recalls/TSBs owners mention: NHTSA Campaign 23V116000 (Power Train clutch recall); parts not yet available at time of complaints; repair timeline exceeded reasonable duration in multiple cases (4 months reported); one vehicle (Complaint 5) failed after recall repair supposedly completed; dealer told owners manufacture had not provided remedy or parts.
Rear Locker Control System Malfunction

When: Complaint 6: ~24,137 miles; Complaint 16: unspecified timing (occurring while traveling)
Symptoms owners cite: Cannot shift out of neutral; Cannot shift into park; Drivetrain stops vehicle from moving; Vehicle will not start
Camshaft and Rocker Arm Failure
Camshaft failure along with rocker arms and cam phasers. Issues started after warranty expired. Owner reports component failures cascade—fixing one problem results in more failures. Vehicle also has automatic start/stop light continuously on.

On Sept 23, the vehicle went into the dealership service department to replace an apparent faulty transmission oil pan gasket, and today October 14, my Gladiator had to be towed to the dealership because the problem was not resolved, causing the check engine light to come on and additional loss of transmission fluid, apparently coming from the main seal.
