2017 FORD F-150 RAPTOR

Typical onset: 60,000-120,000 mi

Symptoms: Metallic knocking at idle that worsens under load, Low oil pressure warning, Metal shavings in oil filter, Sudden loss of power

Fix: The gen-2 3.5L EcoBoost HO has known issues with rod bearing clearances and oiling under high stress. Debris from cam phaser wear can also circulate and damage bearings. Fix requires complete engine rebuild or replacement. Short block replacement takes 18-24 hours, full rebuild 25-35 hours depending on machine shop turnaround.

Estimated cost: $8,000-15,000

Typical onset: 40,000-80,000 mi

Symptoms: Transmission fluid leaking near radiator, Overheating transmission temperature warnings, Milky or discolored transmission fluid indicating coolant cross-contamination, Transmission slipping or harsh shifts

Fix: The factory cooler lines corrode internally or develop leaks at crimp points, and when they fail internally, coolant mixes with ATF destroying the 10R80 transmission. Requires cooler line replacement and full flush at minimum. If cross-contamination occurred, transmission replacement needed. Line replacement is 2-3 hours, transmission replacement 12-16 hours.

Estimated cost: $400-800 for lines only, $5,500-8,500 with transmission replacement

Typical onset: 50,000-100,000 mi

Symptoms: Cold-start rattle lasting 3-10 seconds, Check engine light with cam/crank correlation codes (P0016, P0017, P0018, P0019), Rough idle, Reduced power and fuel economy

Fix: EcoBoost phasers fail due to design issues, and metallic debris from failing phasers circulates through the engine damaging bearings. Requires both cam phasers, timing chains, guides, and tensioners. Critical to replace before catastrophic failure. 14-18 hours labor for phaser job on this engine.

Estimated cost: $3,500-5,500

Typical onset: 30,000-70,000 mi

Symptoms: Clunking when shifting into gear, Excessive driveline vibration under acceleration, Visible sagging or torn rubber in transmission mount, Harsh engagement from park to drive

Fix: The Raptor's aggressive driving style and power output tears the factory transmission mount prematurely. The mount literally tears apart from the bracket. Simple replacement, but quality aftermarket units recommended over OEM. 1.5-2 hours labor.

Estimated cost: $300-500

Typical onset: 60,000-100,000 mi

Symptoms: Rattling noise from engine bay at idle or light throttle, Loss of boost pressure, Check engine light with boost control codes, Reduced acceleration

Fix: Wastegate actuator rods wear and develop play, causing rattle and eventually boost control issues. Can sometimes be adjusted, but often requires turbocharger replacement. Each turbo replacement is 6-8 hours labor.

Estimated cost: $1,500-2,800 per turbo

Typical onset: 70,000-110,000 mi

Symptoms: Hard starting especially when hot, Rough running and misfires under load, Fuel pressure codes (P0087, P0088), Stalling or no-start condition

Fix: The direct-injection high-pressure fuel pump fails internally, sending metal debris through the fuel system contaminating injectors. Requires pump, filter, and often all six injectors if contamination occurred. Pump replacement is 3-4 hours, with injectors adds another 4-6 hours.

Estimated cost: $1,200-2,000 pump only, $3,500-5,000 with injectors
