I just completed a 1100 km trip with my 2022 Limited and the UC5 worked correctly about 50% of the time when starting the truck.
I tried to cold restart by pressing the power button for just over 10 seconds, until the screen goes off. The cold restart doesn’t fix anything. Each time the UC5 reboots and does a complete startup from the ‘loading’ and ‘accept’ screens, the screen pages jump up and down and the selection softkeys on the bottom never appear.
To make the UC5 system work correctly, I have to park the truck, turn it off and let the system shut right down. When I restart the truck, if the UC5 system goes to the ‘loading’ screen, it will not boot up correctly.
In my travels this weekend I had to stop three times, shut off the truck and restart, just to make UC5 work correctly.
This has happened ever since the last oner the update was installed FCA-MY24.U35.26-PROD.
