2022 FORD F-250

Typical onset: 20,000-60,000 mi

Symptoms: Sudden metallic knocking or rattling from engine bay, Loss of oil pressure warning, Check engine light with misfire codes, Metal shavings in oil during routine changes, Complete engine seizure in worst cases

Fix: This is a full short block replacement or complete engine rebuild involving all pistons, rings, bearings, and often crankshaft. Ford has issued TSB 23-2472 acknowledging manufacturing defects in early 7.3L builds (piston skirt cracking, bearing debris). Warranty coverage varies; out-of-warranty jobs run 40-60 hours labor plus $8,000-12,000 in parts. Some owners report Ford goodwill assistance even past warranty.

Estimated cost: $15,000-22,000

Typical onset: 40,000-80,000 mi

Symptoms: Transmission fluid puddle under truck (passenger side, mid-frame), Burnt transmission fluid smell, Harsh shifting or slipping when fluid level drops, Pink or red fluid mixed in coolant reservoir in severe cases

Fix: The cooler lines to the 10-speed's external cooler corrode or crack at crimped fittings, especially in salt-belt states. Replacement involves new hard lines and sometimes the cooler itself if contamination occurred. 3-5 hours labor depending on cab clearance and whether cooler is replaced. Flush system and verify no coolant cross-contamination.

Estimated cost: $800-1,800

Typical onset: 60,000-120,000 mi

Symptoms: Hard starting after sitting overnight (air in fuel system), Extended cranking before firing, White smoke on cold start, Loss of power under load, Fuel puddle on top of engine or frame rail

Fix: The secondary fuel filter housing (frame-mounted) develops hairline cracks or O-ring leaks, allowing air to enter the high-pressure system. Replacement housing with updated seals is the fix. Ford revised the design mid-2021. 2-3 hours labor including fuel system priming and bleed procedure. Use OEM housing; aftermarket quality is inconsistent.

Estimated cost: $600-1,200

Typical onset: 50,000-90,000 mi

Symptoms: Clunk on hard acceleration or deceleration, Vibration at idle in Drive, Visible sag or torn rubber on crossmember mount inspection, Driveline shudder during 2-3 upshift

Fix: The rear transmission mount (crossmember-style) fatigues under the torque of both engines, especially with towing. Mount itself is $150-250, 1.5-2.5 hours labor depending on exhaust and driveshaft clearance. Not a safety issue but accelerates driveline wear if ignored. Upgraded polyurethane mounts available but increase NVH.

Estimated cost: $400-700

Typical onset: 80,000-140,000 mi

Symptoms: Gradual coolant loss with no external leaks, White smoke from exhaust after warm-up, Check engine light with EGR flow codes (P0401, P0402), Overheating under load, Sweet smell from exhaust

Fix: Fourth-gen 6.7L improved EGR reliability, but coolers still clog with soot or develop internal leaks (coolant into exhaust). Delete is illegal; proper fix is OEM cooler replacement and full EGR system cleaning. 6-9 hours labor, requires cab removal on some configurations for access. Use Ford coolant spec only (VC-13-G); aftermarket coolants accelerate corrosion.

Estimated cost: $2,200-3,800

Typical onset: 30,000-70,000 mi

Symptoms: Ticking or hissing noise from engine bay (worst on passenger side), Exhaust smell in cabin, Visible soot around manifold-to-head interface, Louder exhaust note under throttle

Fix: Cast iron manifolds on the 7.3L develop stud failures due to thermal cycling, similar to older Ford V8s. Requires drilling out broken studs, re-threading, and installing time-serts or helicoils. Manifolds often warp and need resurfacing or replacement. 4-7 hours per side. Preventive retorquing at 30k miles helps but isn't in service schedule.

Estimated cost: $1,200-2,400
