- [SGI18\-05](/bulletins/10138657.md), 2018-05-29, Service bulletin: POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE \(TCM/PCM/TECM\); ELECTRICAL SYSTEM. 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.
