What is the 2017-2020 Ford F-150 3.5L EcoBoost cam phaser rattle on cold start?

Second-gen 3.5L EcoBoost engines develop a loud rattle/knock from the front timing cover for 2-5 seconds on cold start (and sometimes at idle). The variable-cam-timing (VCT) phasers have a lock pin that fails to engage on startup, allowing the phaser to rattle against the cam spr… Repairs typically run $800-$3,600. Severity: high.

What is the 2015-2022 Ford F-150 2.7L EcoBoost Coolant Intrusion from Cracked Cylinder Head?

Ford's 2.7L EcoBoost (and related small-displacement EcoBoost engines) is prone to micro-cracks forming in the cylinder head around the exhaust ports, allowing coolant to seep into the combustion chamber. This produces unexplained coolant loss with no external leak, white sweet-s… Repairs typically run $4,000-$8,000. Severity: high.

What is the 2017-2023 Ford F-150 10-Speed Transmission Shudder/Harsh Shifts?

The 10R80 10-speed automatic transmission can develop a shudder during light acceleration, typically between 25-50 mph. This is caused by torque converter clutch issues and affects many F-150s. Ford has released multiple TSBs and fluid updates to address this. Repairs typically run $200-$3,500. Severity: medium.

What is the 2015-2020 Ford F-150 EcoBoost Oil Pan Leak?

The EcoBoost engines can develop oil leaks from the oil pan gasket. The leak often appears at the rear of the oil pan and can drip onto exhaust components, causing a burning oil smell. This is common on trucks with higher mileage. Repairs typically run $400-$1,200. Severity: medium.

What is the 2015-2020 Ford F-150 Driveshaft Carrier Bearing Failure?

The two-piece driveshaft uses a center support (carrier) bearing that can wear out, causing vibration and noise. The rubber support degrades over time, especially in hot climates or with heavy towing. Ford TSB addresses this issue. Repairs typically run $300-$700. Severity: medium.

What is the 2017-2021 Ford F-150 Water Pump Leak/Failure (3.5L EcoBoost)?

The water pump on the 3.5L EcoBoost can fail or develop leaks, causing coolant loss and potential overheating. The pump is internal and driven by the timing chain, making replacement labor-intensive. Repairs typically run $800-$2,000. Severity: medium.

What is the 2004-2020 Ford F-150 Exhaust Manifold Studs / Bolts Break — Exhaust Leak and Cold-Start Ticking?

Ford modular V8s (and the EcoBoost V6 turbo manifolds) are notorious for snapping the small (8mm) exhaust-manifold-to-head studs/bolts. They are installed without anti-seize and corrode/fatigue from repeated heat cycling; on the turbo EcoBoost engines, a large share of the turbo/… Repairs typically run $50-$700. Severity: medium.

What is the 2015-2020 Ford F-150 Front Wheel Hub Bearing Assembly Failure — Humming Noise and ABS Light?

The sealed, non-serviceable front hub/bearing assemblies on 13th-gen F-150s wear out and produce a speed-dependent humming or grinding that gets louder with speed and can shift with cornering load, plus steering-wheel/floor vibration. Because the wheel-speed sensor lives in the h… Repairs typically run $300-$750. Severity: medium.

What is the 2011-2020 Ford F-150 3.5L EcoBoost Fuel Injector Failure — Startup Misfire, Rough Idle, and Fuel-Injector DTCs?

The 3.5L EcoBoost's high-pressure direct (GDI) injectors run at diesel-like pressures and are a common failure item, especially at higher mileage and after heat-soak. A stuck-open or electrically failing injector floods a cylinder and can wash down neighboring cylinders on the sa… Repairs typically run $650-$1,500. Severity: medium.

What is the 2004-2024 Ford F-150 IWE (Integrated Wheel End) Failure — Front-End Grinding and Partial 4x4 Hub Engagement?

Ford's 4x4 F-150s use a vacuum-operated Integrated Wheel End (IWE) system instead of conventional locking hubs: vacuum keeps the front hubs UNLOCKED in 2WD and is released to lock them for 4WD. The system relies on vacuum lines, a hood-area solenoid, and a check valve that are hi… Repairs typically run $100-$700. Severity: medium.

What is the 2018-2020 Ford F-150 5.0L Coyote (Gen 3) excessive oil consumption?

Third-generation 5.0L Coyote V8 trucks consume oil at an abnormally high rate (greater than ~1 quart per 3,000 miles) with no visible external leaks. Ford TSB 19-2365 attributes it to high intake-manifold vacuum during deceleration fuel shut-off pulling oil past the rings/valve g… Repairs typically run $0-$2,000. Severity: medium.

What is the 2018-2020 Ford F-150 5.0L Coyote Excessive Oil Consumption from Deceleration Fuel Shut-Off?

Third-generation 5.0L Coyote F-150s consume engine oil at a high rate — greater than 1 quart per 3,000 miles — with no visible external leaks. Ford attributes the loss to high intake-manifold vacuum during deceleration fuel shut-off (DFSO) events pulling oil past the rings, valve… Repairs typically run $0-$400. Severity: medium.

What is the 2009-2024 Ford F-150 Center High-Mount Stop Lamp (Third Brake Light) Gasket Leak — Water Intrusion into Cab?

The foam gasket that seals the roof-mounted center high-mount stop lamp (CHMSL / third brake light) against the cab dries out, compresses and shrinks with heat and UV exposure, breaking the watertight seal. Rainwater then runs down inside the cab from the roof opening, soaking th… Repairs typically run $40-$250. Severity: medium.
