I have been experiencing the same -no start issue on 2015 LE. It will start fine initially, regardless of ambient temp! It is when I shut it off at a stop for 10-15 minutes and go to re-start. Turns and turns with no ignition. Wait and try again...it eventually goes but embarrasing. Hard to believe its a "warm the relays" issue as the sled is at operating temp!?!?
