# Service bulletin Bulletin 13H3

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: 10185255
- Published by NHTSA: 2021\-01\-08
- Manufacturer's number: Bulletin 13H3
- Manufacturer's date: 2020\-12\-01
- NHTSA component: ENGINE; EQUIPMENT ADAPTIVE/MOBILITY

## NHTSA's summary

The engine may not run smoothly due to a non\-optimal control of the camshaft adjuster during specific operating conditions. In rare cases, the engine may even stop running under these conditions. However, it is possible to restart the engine at any time afterwards. Internal research has shown that the issue can only occur when the engine is idling \(i.e. when the vehicle is stationary or just before the vehicle comes to a stop\).
