# 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.

- Type: Service bulletin
- NHTSA id: 11017479
- Published by NHTSA: 2025\-05\-02
- Manufacturer's number: 09\-004\-25a

## 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.
