# Service bulletin PIP5179D

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: 10137203
- Published by NHTSA: 2018\-05\-21
- Manufacturer's number: PIP5179D
- Manufacturer's date: 2018\-03\-27
- NHTSA component: ENGINE; FUEL SYSTEM, GASOLINE:FUEL INJECTION SYSTEM

## NHTSA's summary

This Preliminary Information communication provides information to the technician about vehicles that have extended or long crank time during cold ambient air temperatures. Direct Injection systems run at higher pressures, and the mechanical pump on the engine must build up the required pressure before the first injection event occurs. Direct Injection engines may have slightly longer cold crank times than that of port fuel engines.
