2015 JK Hot Oil Warning (-58 degrees)

[Bruce]

Following a snow storm I started my 2015 Wrangler Sport in the driveway to warm it up and clear the snow with no problems. More snow came 2 days later and when I went to start it up 4 days later I now have all the warning lights lit up and chiming with a hot oil warning. The transmission temp reads -58F. The vehicle starts and drives but the speedometer does not work. What the heck happened and what needs to done to get back to normal? It rarely snows in south Texas and this has never happened before.

You could have a bad connection, damp weather can cause that. I'd start with cleaning the battery clamps and cables and checking any other grounds in the engine bay area.

X2 on what @BLACKJKU said. Electronics don't like cold temps with moisture. cold temps make things shrink which can let moisture in causing corrosion or a bad connection.
