Official summary
Some vehicles may experience "Blind Spot Monitoring Sensor(s) Blocked" displayed in the instrument cluster while driving over 37 mph {60 km/hr.} in areas without structures or buildings around the vehicle. This may be caused by a partial defect in the blind spot monitoring (BSM) control module. To eliminate this concern, the blind spot monitoring (BSM) control module has been modified.
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.
