Official summary
All 2021 Bronco Sport vehicles have headlamp low beam pattern with a dark spot dip near the horizon in the left portion of the beam pattern. These dark spots are most noticeable when the high beam is active. Although this dark spot is present by design, this issue may be more perceivable to the customer if the headlamps are aimed too low (dark spot will appear closer to vehicle). The vertical aim should be checked and adjusted upwards if necessary, refer to Workshop Manual (WSM) Section 417-01.
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.
