Official summary
On some Model S, Model X, and Model 3 vehicles, condensation might build up inside of the B-pillar applique, potentially obscuring the B-pillar camera. This condition might cause some Autopilot features to be temporarily unavailable until the condensation goes away, such as Auto Lane Change, Blind Spot Detection, and Lane Departure Warning.
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.
