# Service bulletin SB\-19\-20\-003 R2

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: 10181263
- Published by NHTSA: 2020\-10\-19
- Manufacturer's number: SB\-19\-20\-003 R2
