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 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 2015-2023 Ford F-150 Coolant Degas / Overflow Bottle Cracks and Quick-Connect Fitting Leaks?

The plastic pressurized coolant degas (overflow/expansion) bottle and the plastic quick-connect tees/Y-fittings that route coolant between the block, radiator, and bottle develop hairline cracks and seep, especially at seams and hose necks and in cold weather where the square-cut… Repairs typically run $150-$450. Severity: medium.

What is the 2015-2020 Ford F-150 Panoramic / twin-panel sunroof spontaneous shattering?

F-150 trucks equipped with the large twin-panel (panoramic) sunroof have reports of the tempered glass spontaneously shattering or 'exploding' with a loud bang, sometimes at highway speed, raining glass into the cabin. Owners and a class action attribute it to the ceramic enamel… Repairs typically run $500-$1,500. 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 2015-2024 Ford F-150 Swollen Two-Piece Lug Nuts Preventing Tire Removal?

Ford's two-piece factory lug nuts (a steel core with a thin chromed/stainless decorative cap) trap moisture between the layers. The steel core corrodes and the resulting rust bloom swells the cap outward, so the standard 21mm/22mm socket and the truck's own lug wrench no longer f… Repairs typically run $40-$200. 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 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 2004-2020 Ford F-150 Rear Differential Pinion Bearing / Ring-and-Pinion Whine and Howl?

The rear axle (commonly the 8.8-inch) develops a speed-dependent whine or howl as the pinion bearing and ring-and-pinion gears wear, often the most common source of axle noise on Ford trucks. The noise typically appears under acceleration or on deceleration and changes with throt… Repairs typically run $500-$1,600. Severity: medium.
