Error code 01336 From radio

Along with this strange behavior:

When driving, if the radio is on longer than ~1 hour it will shut itself off. I also have to turn it off and on manually because when i turn the car off it stays on for some reason. Any ideas?

This is associated symptom with the ignition switch, ...

Normally, the radio will continue to play for about 1 hr after turning the engine OFF, Provided the key is in the ignition switch. The radio will turn OFF, when the key is removed from the ignition switch. From your description, is follows that the ignition switch is not sending the "key inserted/removed" status to the steering column control module. The SCCM, uses the ignition key inserted/removed status from the switch, and sends a control message on the infotainment CAN buss to either: keep the radio ON if already ON Key inserted, or to turn OFF the radio when the key is removed from the switch.
The Immobilizer also uses the key inserted/removed status to assert immo engine start authority according to the key insertion status. The symptoms involving the radio key OFF run time, and the intermittent immo assertion of engine start authorization, are both involved with a functional failure of the ignition switch, or the electrical connections to the Steering Column Control Module are faulty.
