I'll take a look at ours, but it seems like we just has our update this week. Same issue as before...all the "warning" lights turn on (traction control failure, check engine, etc..), then one by one, they turn off after the update, with the check engine light turning off last. We connected our series III to the home WiFi and hopefully the update process will run smoother.
Regarding the "warning" and "failure" lights. Although it's been causing the wife all manner of anxiety, its just the process of owning a car with all this new tech...I've resigned myself to the fact that these notices will continue to turn on/off during the updates and reboot processes for the next few months. Kinda crappy for a >80k SUV!
Fortunately, nothing mechanically seems to be wrong with the car (not yet)
