# Service bulletin 01\-007\-17\-3349

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: 10120346
- Published by NHTSA: 2017\-10\-21
- Manufacturer's number: 01\-007\-17\-3349

## NHTSA's summary

Some vehicles may exhibit a lack of engine power / intake air leak noise from the engine compartment. Hose clamps A and/or B for the air hose \(C\) for the turbocharger air outlet pipe \(D\) may be loose due to insufficient tightening. The tightening torque of the hose clamps has been increased to eliminate this concern.
