2016 FORD F-150

Typical onset: 80,000-150,000 mi

Symptoms: Cold-start rattle or knocking lasting 3-10 seconds, Check engine light with cam/crank correlation codes (P0016, P0018), Metal shavings in oil during changes, Loss of power, rough idle as wear progresses

Fix: Cam phasers fail due to oil debris from timing chain wear. Advanced cases damage bearings,pistons, cylinder walls. Early catch: phasers and chains (12-16 hrs labor). Late catch: short block or full rebuild (25-40 hrs). Both EcoBoost engines affected, 2.7L slightly worse statistically.

Estimated cost: $3,500-9,500

Typical onset: 60,000-120,000 mi

Symptoms: Transmission fluid leak at radiator connection or along frame rail, Sudden transmission slipping or no movement, Pink fluid pooling under truck, Overheating transmission warning

Fix: Quick-connect fittings at radiator crack or corrode, especially in salt states. Line can rupture completely, dumping all ATF in minutes. Replace cooler lines and flush system if caught early (3-4 hrs). If driven low on fluid, expect internal trans damage requiring rebuild (18-24 hrs).

Estimated cost: $800-5,000

Typical onset: 30,000-80,000 mi

Symptoms: Hard downshifts from 3rd to 2nd or 2nd to 1st, Shudder or vibration during light acceleration at 20-40 mph, Clunk when shifting into reverse, Hunting between gears on highway

Fix: 10R80 transmission programming issues and torque converter clutch shudder. Most cases fixed with TSB software updates (1 hr) and fluid change using Mercon ULV. Persistent cases need torque converter replacement (8-10 hrs). Note: Only applies to 2017+ models; 2016 has 6-speed which is more reliable.

Estimated cost: $150-2,800

Symptoms: Sudden loud hissing or popping from engine bay, Immediate misfire and check engine light, Loss of compression on one cylinder, Spark plug physically blown out of head

Fix: Aluminum head threads strip under heat cycling, launching plug out. Requires HeliCoil or TimeSert thread repair on affected cylinder (4-6 hrs if head stays on, 12-16 hrs if head removal needed for proper repair). Some shops try quick inserts—avoid these. Can happen at any mileage, even under 50K.

Estimated cost: $800-3,200

Typical onset: 50,000-100,000 mi

Symptoms: Door won't open from inside or outside handle, Double-pull required to unlatch door, Door ajar warning stays on with doors closed, Power locks cycling or not working on one door

Fix: Internal latch mechanism gears strip or actuator motor fails. Recall 18S32 covered some VINs but not all. Requires door panel removal and latch replacement (1.5-2.5 hrs per door). Driver and rear passenger doors most common. Original parts fail again; aftermarket hit-or-miss.

Estimated cost: $350-600

Typical onset: 40,000-90,000 mi

Symptoms: Grinding or clicking from front wheels during acceleration, Noise worse in cold weather or after sitting overnight, 4WD won't engage or engages intermittently, Hissing sound from under hood

Fix: Vacuum lines crack, solenoid fails, or IWE units themselves lock up. Front hubs don't fully disengage, causing drivetrain binding in 2WD. Replace IWE units both sides and vacuum solenoid (3-4 hrs). Check valve and lines another 1-2 hrs. Very common on trucks in freeze/thaw climates.

Estimated cost: $800-1,400

Symptoms: White powdery corrosion at bed-to-frame mounting areas, Bubbling paint on cab corners near steel subframe, Corrosion between aluminum tailgate and steel hinges, Hood or fender edges pitting near steel brackets

Fix: Galvanic corrosion where aluminum body meets steel frame without proper isolation. Cosmetic but progressive. Requires panel removal, corrosion treatment, isolator replacement, and refinish (varies widely, 4-12 hrs depending on location). Ford applied better isolators in later years. Not a safety issue but expensive to repair correctly.

Estimated cost: $600-2,500
