Error notification -Service required


Jun 25, 2014
Colorado Springs, CO
Hey all - trying to figure out a new alert that came up on the dashboard. It reads, “Service is required - use mobile app to schedule service”. If you go to the notifications pop up on the main screen it lists an error code GTW_w026. I can’t find any information about this error code anywhere. Scheduling an appt is possible, but won’t help for weeks. I need to know whether it is safe to drive the car or not. I am in the extended service period with a 2016 Model S, about 60k miles. I did recently swap out the battery for an Ohmmu after getting the 12v alert, but this went without issue and the car was driving fine for about a week afterwards without any alerts.

Anyone else experience this alert or know how to find out what is causing it?
