2018 Model X New MCU LTE Failure

Woke up yesterday to not having LTE/3G or wifi internet access. Has anyone else experienced this issue?

Have you tried to reboot?

The various reboot methods don't seem to work on the new MCU in our X ("Rare" issue per support). I have powered off the car and let it sit overnight but nothing.

Sounds like failure in the MCU itself. I'd contact service.

I contacted them over the weekend and have yet to hear back.

@familytesla80
I had a case of voice commands not working. Also event though LTE was showing as connected, the maps were not showing traffic information.

I pulled into a parking lot and did the brake+both scroll wheels reboot. After that everything was fine. A simple reboot (just scroll wheels) did not fix it.

Happy to report that, per Tesla engineering, 2018.14.2 a88808e resolved the issues we were seeing.
