The failure pattern owners describe

Owners describe a cascade of electrical failures in 2021 F-150s. Battery drain without obvious cause, often paired with AC malfunction, leaves vehicles unable to start after parking. Alternators fail suddenly, disabling power steering and forcing unwanted park shifts mid-drive. Gateway module software faults trigger "Stop Safely Now" warnings and complete power loss at highway speed, leaving drivers stranded in traffic.

Trailer systems are particularly problematic. Brake controllers lose recognition of connected trailers; owners apply brakes only to discover they're inoperable. Some report trailer push-back incidents where failure to engage trailer brakes caused off-road excursions. Trailer brake lights fail; false "trailer attached" warnings persist after disconnection.

Software-related failures plague infotainment and cluster displays. Screens go completely black; instrument clusters reboot while driving at 30–65 mph, leaving drivers without speedometer or vital gauges. Audio systems spike to 100+ decibels without user input. A few owners report soy-based underbody wiring chewed by rodents, leaving vehicles unable to start or steer.

One owner's vehicle caught fire after 15 miles; another reported unintended airbag deployment without collision. Parking brake systems engage unexpectedly or malfunction, with some recalls performed twice yielding no fix. Dealerships often decline repeat recalls citing prior service history, leaving owners responsible for costs.

Cluster will randomly shut off causing all gauges to act like the vehicle isn't on. Then it will turn back on.
