The 2017 F-150 is a solid workhorse, but the 3.5L EcoBoost V6 has serious durability issues and the 10-speed transmission had teething problems. The 5.0L Coyote and naturally-aspirated 3.5L are far more reliable choices.
3.5L EcoBoost Cam Phaser Failure and Timing Chain Stretch
Common · high severityTypical onset: 80,000-150,000 mi
Symptoms: Cold-start rattling for 2-3 seconds, Check engine light with cam/crank correlation codes, Loss of power on acceleration, Rough idle
Fix: Requires timing chain replacement, cam phasers, and often VCT solenoids. 12-16 hours labor due to tight engine bay. Some shops recommend doing oil pump and guides while in there. This is a known weak point on 2nd-gen EcoBoost engines.
Estimated cost: $3,500-5,500
10R80 Transmission Hard Shifts and Shudder
Common · medium severityTypical onset: 30,000-80,000 mi
Symptoms: Harsh 2-3 or 3-4 upshifts, Shudder during light acceleration at 30-50 mph, Delayed engagement from park, Clunking when shifting to reverse
Fix: Early production units need software updates (TSB 18-2431). Persistent cases require torque converter replacement or valve body work. Fluid and filter service sometimes helps temporarily. 6-8 hours for torque converter.
Estimated cost: $2,000-3,800
Transmission Oil Cooler Line Leaks
Common · medium severityTypical onset: 60,000-120,000 mi
Symptoms: Pink fluid spots under truck, Transmission overheating warning, Low transmission fluid level, Fluid dripping near radiator area
Fix: Steel cooler lines rust through where they contact frame or corrode at crimp fittings. Replace lines in pairs with upgraded aftermarket or updated Ford parts. 2-3 hours labor, straightforward job.
Estimated cost: $400-800
2.7L EcoBoost Carbon Buildup and Turbo Failure
Occasional · high severityTypical onset: 90,000-140,000 mi
Symptoms: Loss of boost pressure, Blue smoke on startup, Misfires and rough running, Turbo whistle or grinding noise, Oil consumption over 1 quart per 1,000 miles
Fix: Direct injection causes valve carbon buildup requiring walnut blasting every 80k-100k miles (4-5 hours). Turbo failures often from oil starvation or carbon blockage. Single turbo replacement is 8-10 hours due to access.
Estimated cost: $2,200-4,000
Door Latch Failures (Recall 17V-605 & 20V-134)
Common · medium severitySymptoms: Door won't close or latch properly, Door appears closed but warning light stays on, Door pops open while driving, Unable to open door from inside or outside
Fix: Ford issued multiple recalls for faulty pawl spring clips in door latches. Should be covered under recall, but out-of-recall units fail too. 1-2 hours per door to replace latch assembly.
Estimated cost: $250-450
3.5L EcoBoost Piston Ring Failure and Oil Consumption
Occasional · high severityTypical onset: 100,000-180,000 mi
Symptoms: Burning more than 1 quart per 500 miles, Blue exhaust smoke on acceleration, Fouled spark plugs, Loss of compression, Carbon buildup in combustion chambers
Fix: Ring lands crack or rings collapse from detonation and high cylinder pressures. Requires complete engine teardown, new pistons and rings minimum. Many shops recommend short block. 25-35 hours labor.
Estimated cost: $6,500-12,000
Brake Master Cylinder Leaks (Recall 19V-700)
Occasional · high severityTypical onset: 40,000-90,000 mi
Symptoms: Spongy brake pedal, Pedal slowly sinks to floor when held, Brake fluid dripping down pedal assembly inside cab, Low brake fluid warning
Fix: Master cylinder seal fails internally. Covered under recall 19V-700 but later units outside recall window still fail. Straightforward replacement, 2-3 hours including bleeding entire system.
Estimated cost: $450-750
Buy the 5.0L V8 or base 3.5L V6 with eyes open on the transmission; avoid the EcoBoost V6s unless you enjoy expensive engine work.
