# Service bulletin SSM 51290

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

This may be due to a front turn signal lamp socket being internally damaged. To correct this condition, replace the affected front turn lamp socket before replacing the BCM.
