Sounds similar to our problem. Loss of power steering? If so, tell the Mt. Kisco ScC to call Dublin CA. It's a 5 minute fix (at least it was for me two times). I know the second time was immediately after a software update. I'm pretty sure the first time was also, but can't confirm that 100%. The FWD recalibrate was something I only saw after the fix was done. The fix is a total vehicle reboot. They disconnected the high voltage power then the negative lead off the 12v battery. Waited several minutes that reconnected in reverse order. Upon reboot power steering was back. The tech and I are speculating that it's something to do with the sequence of bringing systems back online after a software reboot. According to Dublin they had about 3 or 4 the same day I had my first experience with the problem. Mine also was delivered mid Sept.



At this juncture I will only do a update to firmware if I'm parked at a SvC that is open and has agreed to reboot my car or someone from Tesla tells me they've figured out the problem and the fix is in the update being pushed out. Currently I'm on 40.1.



Except for the software engineers pushing software out the door without testing I'm really really happy with our X. Just got back from a week long mountain trip. It's a great car.
