Service bulletin 09-004-25a

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's 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.
