2021 Jeep grand cherokee

I have a jeep grand Cherokee that recently started spitting and sputtering losing all power. First time it acted up we had a message pop up to shift to park. So we pulled over and put in park and then the steering wheel locked up and could not move shifter. We then turn off ignition and restarted then acted normal for awhile. We still this spitting and sputtering without getting the shift to park popping up but we stull use the pull over shift to park and shutoff restart to get it to run ok for awhile. Took to our mechanic and had him run diagnosis on his snap on computer and got 3 codes: B1561-13, B224E-96, and B2860-15. Anyone know what could cause this and/or a fix or place to start? Dealer screwing me around.. 28,100 miles on vehicle.

Open or Short DTC:
B1560-11
B1560-13
B1561-11
B1561-13

Discussion: “Uconnect Box requires service” message popup on the radio screen when vehicle starts. wiTECH shows one or more active or stored DTC(s):
• B1560-11 - Cellular Antenna 1: Circuit Short to Ground
• B1560-13 - Cellular Antenna 1: Circuit Open or Short to Battery
• B1561-11 - Cellular Antenna 2: Circuit Short to Ground
• B1561-13 - Cellular Antenna 2: Circuit Open or Short to Battery
Every time the antenna open or short DTC(s) was set, the Uconnect box error popup will show on the screen. The message will stay on until next ignition off or customer closes the popup by pressing the cross button at top right corner of the screen.

Please check the antenna harness connections on both TBM and antenna for proper installation,
damaged connector locks, bent terminals or terminal push out. Check harness continuity and for cable pinch or damage.
Do not replace the TBM module, if it could not be duplicated and DTC becomes stored. Most likely this was due to an intermittent harness connection concern.
