# Service bulletin N048NAS2

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: 10125224
- Published by NHTSA: 2017\-12\-14
- Manufacturer's number: N048NAS2
- Manufacturer's date: 2017\-07\-11
- NHTSA component: ENGINE AND ENGINE COOLING

## NHTSA's summary

Situation: An issue has been identified on certain vehicles within the listed Affected Vehicle Range may have been manufactured away from process and in some cases, a front fender has been installed without air flow ducts. Investigations have identified that the air ducts are required to aid brake cooling and therefore, where customers are using their vehicle enthusiastically, an increase in pedal travel after repeated high speed stops may be experienced.
