Official summary
Some 2021-2022 Bronco vehicles equipped with the 2.3L engine may exhibit a red brake warning lamp and/or brake system warning message in the instrument panel cluster (IPC) with a diagnostic trouble code (DTC) P050F in the anti-lock brake system (ABS) module and a firm brake pedal. This may be due to contamination in a brake booster vacuum line. To correct this condition, replace the vehicle's vacuum hose (MB3Z-2420-A). Refer to Workshop Manual (WSM), Section 206-09 for installation instructions. For claiming, use casual part 2420.
Vehicles covered
What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
