Hi, we just purchased (new to us) our first EV and we did alot of research and pulled the trigger on a 2014 i3 REX, had it for three days fully happy with it however... the connected app and remote preconditioning is very important to as here in Phoenix Arizona it's 110 degrees outside and we wanted to be able to precool our car while plugged in (garage) so we could save the battery for miles instead of cooling down a very hot car. Soo here is the problem. We have only had the car for 4 days - first day (in our garage) fire up the app, ask alexa to cool off the car the preconditioning works great! show it off to friends and family , next day I have the coneected drive apps added to the car (you know the apps like pandora paid $50) try to start preconditioning (it fails) try many times again all fail, try doors unlock/lock all fail. Call BMW they work me thru what seems hours of resetting the car, every result ends in connection fails from either the app or the desktop - will not communicate. Get BMW to remove the connected drive app, and set up an appointment for dealer service, Telemetrics? and today (just for fun) I try and lock/unlock doors while my wife is at work 30 miles away it WORKS perfectly! She gets home tonight, (car in garage) try to lock doors (fails) WTF? do I still bring it in for service? Or is my garage in a wierd dead zone? Why did it work so great the first day? Does anyone have any experiance with this? one of the reasons we bought this car was for the preconditioning.
