Just got a brand new (600 miles) 2021 Rubicon with the 8.4 Uconnect and 3.6 e-torque. The entire screen and all the controls below started shutting down every time engine is started or put into run mode. The screen will come on and radio will play while in ACC, but as soon as soon as you start car the whole system shuts down. Basically the only electronics that work are the instrument cluster behind steering wheel and lights. I have tried various different ways to reset the system including disconnecting battery, but nothing has worked. I can drive it, but no radio and the front defrost is on high which I can not change since the climate controls are out. I have contacted my dealer and they are doing research before I bring it in. They are an hour away so trying to exhaust all options before I make that trip. I have seen a lot of threads on here about Uconnect shutting down, but not specifically only in run mode or on newer JL's. Has anybody had a similar issue or got any ideas. TIA!
