What is the 2015-2020 Ford F-150 Brake Vacuum Pump Failure (EcoBoost)?
The vacuum pump that provides brake assist on EcoBoost F-150s can fail, resulting in a hard brake pedal and reduced braking assist. Since turbo engines don't produce intake vacuum like naturally aspirated engines, they rely on this pump. Repairs typically run $300-$800. Severity: high.
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 2017-2023 Ford F-150 10R80 10-speed transmission harsh/erratic shifting and torque-converter shudder?
The 10R80 10-speed automatic (introduced on the 2017 F-150) is widely reported to shift harshly: jerking, clunking, banging on the 1-2 and 2-3 shifts, hesitation, gear hunting, and occasional limp-mode with a 'Transmission Not in Park' or 'drive mode not available' message. Many… Repairs typically run $150-$4,500. 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 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 2018-2021 Ford F-150 5.0L Coyote Cam Phaser Tick/Rattle?
The 5.0L Coyote V8 can develop a ticking or rattling noise at startup, often from the cam phasers. This is similar to issues in the Mustang GT. The noise typically diminishes after the engine warms up but can indicate phaser wear. Repairs typically run $0-$2,500. Severity: low.
What is the 2015-2023 Ford F-150 HVAC Blend Door Actuator Failure?
The HVAC blend door actuators can fail, causing clicking noises from the dashboard and inability to control air temperature. Air may blow only hot or only cold regardless of settings. Multiple actuators are used and any can fail. Repairs typically run $100-$500. Severity: low.
