The 10R80 10-speed automatic in 2019-2021 trucks, and continuing through 2024-2025 variants, is prone to harsh or erratic shifts, clunking noises, hesitation when accelerating, and occasional slipping between gears. If left unaddressed, these symptoms can lead to premature wear of the valve body, torque converter, and clutches, potentially requiring transmission replacement. The cited source lists 479 powertrain complaints for 2019 and 332 for 2021, but provides no specific repair cost.

The 3.5L EcoBoost cam phaser problem affects 2019-2020 models and very early 2021 builds built in the first four months, which retained the older phaser design before the redesigned units arrived. Drivers notice a loud rattle or ticking noise on cold start, reduced engine power, and potential timing chain wear if not repaired. Ignoring the issue can lead to catastrophic engine damage requiring a rebuild or replacement, but the cited sources do not state a specific repair price.

The 2024 F-150 has 44 complaints specifically tied to exterior lighting, making it the most common problem area for that model year. Symptoms include headlight or taillight malfunctions, intermittent outages, and dashboard warning indicators. These failures create a direct safety risk during night driving and may lead to failed safety inspections or traffic stops, though no repair cost estimate is provided in the cited source.

The 2025 F-150 has seven reported complaints specifically tied to service brakes, alongside 14 powertrain and 13 electrical system complaints. Symptoms include irregular brake pedal feel, squealing or grinding noises, premature wear, and brake system warning lights. Failure to address these issues can reduce braking performance and increase stopping distances; the cited source does not provide a repair cost.

Early 2021 builds from the first four months have documented software bugs, while the 2024 model recorded 24 electrical-system complaints and the 2025 model recorded 13. Symptoms include infotainment screen freezes or restarts, false warning lights, intermittent sensor failures, and battery drain. These issues can make driver-assist features unreliable and often require repeated dealer visits, but no specific repair cost is listed in the cited sources.
