One problem related to fog light switch has been reported for the 2017 Tesla Model S. The most recently reported issues are listed below.
Touch screen is completely black multiple times per week. Usually at beginning of trips, but occasionally suddenly occurs in the middle of trips. Black out can last upwards of 10 minutes (per smartphone stop watch). Touchscreen blackout limits access to fog light controls, back up camera, garage controls, passenger airbag status indicator, and all audible warnings including emergency brake alert and turn signal noises. The vehicle is covered under Tesla's new extended warranty. I requested service on 10/17. Was scheduled to bring car in on 11/12 (next available). They said it was done on 11/13 after only completing a diagnostic and a firmware flash. No hardware modifications were completed. Same symptoms reoccurred on 11/23. I contacted them that same day and they gave me an appointment of 12/18. Today (11/24) they contacted me to recommend I cancel the appointment as the issue is (they say) software based and they "found no issues with the hardware" via remote diagnostic. Video link below of a recent 7 minute black out. Https://photos. App. Goo. Gl/3bdbafq7ylvjtxfu7 I have attempted multiple forms of reset/reboot when this occurs with no notable improvements.
