This is absolutely ridiculous! This is my 3rd Tesla over the past 5 years and the delivery process in this case is just unforgivable. Got my M3 from the Fremont Delivery Center last Saturday, AFTER a 2 hour delay due to "needing to update firmware." Blowing smoke. But finally got my introduction to the car and with great fanfare, the keyless iPhone entry feature. Worked great for about 18 hours. Then the M3, without warning, stopped showing up on my App. I've now learned that this is supposed to be normal. But NOTHING was ever mentioned during the introduction. So I spent an hour or so the next day trying to figure what was going on, assuming of course that it was something that I did. So I was told on Monday, after calling Tesla Service, that paperwork needed to be completed and the App would magically start showing the M3. NADA today. And we leave for an 800 mile road trip tomorrow. Pretty sure I have the system understood now, but not because of Tesla Support. And still no keyless iPhone entry. The Tesla App is not available for the M3 currently. Presents difficulties in monitoring charging status and the cabin temp for our dog. IMHO they are definitely not ready for prime-time with the M3! I would strongly recommend waiting for delivery a while. And this is from a Tesla fanboy!
