# Service bulletin N118NAS1

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: 10130729
- Published by NHTSA: 2018\-04\-02
- Manufacturer's number: N118NAS1
- Manufacturer's date: 2018\-01\-17
- NHTSA component: POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE \(TCM/PCM/TECM\)

## NHTSA's summary

An issue has been identified on certain vehicles within the listed Affected Vehicle Range where the 'Service Required' message will not appear on the Instrument Cluster \(IC\) if a vehicle has reached its service point and the engine is started normally by pressing the engine START/STOP button with the brake pedal pressed. Turning on the ignition only, by pressing the engine START/STOP button without the brake pedal pressed, will still allow the 'Service Required' warning message to be displayed. In addition, the latest Powertrain Control Module \(PCM\) software has introduced a concern relating to the ability to reset the service message indicator. The latest IC software will rectify these concerns.
