Is anyone else seeing the errors below pop up?
 
"Car needs service - steering assist unavailable"
"Park assist unavailable"
 
The primary issue is that the power steering is not engaging. Given the 6,000 lb beast the
MX is, it is essentially not maneuverable without power steering. The falcon doors have
become nonfunctional too. All this on a 3-week old Tesla! My MX was sitting pretty in the
local SC for the better part of this week. I called in today and they said all was looked at
and fixed. Initial diagnosis I was provided was that the connectors on the relays and EFuse
were lose and were torqued to company specification. Upon further probing, I was told that
the problem is more software related. They have introduced a new module and the
software needs to be fine-tuned. It was also mentioned that the issue could recur and the
only solution as of now is to hard-reboot (disengage 12V battery). This ultimately will only
be fixed with the next software update. 2 hours out of the SC and few miles on, I'm back to
square one. Errors pop up and the steering is stiff again. Luckily I could get home. Quite
irritated with this right now.
 
If it is a software calibration issues/bug, then someone else must have experienced this
too. If not, did I get a lemon?
