Problem:
Radio changing stations up/down, volume up/down and tuning to different radio stations without using the knob
Drive Control System Error message
Unable to shift the car from park to any gear

Diagnosis:
To rule out the transmission I overrode the brake control switch using the emergency switch located by the gear shifter. I moved the car to the reverse and confirmed no issue with grinding and did similar with drive. This helped to POSSIBLY remove transmission as cause.

Using the above method I held down the brake and put the car in reverse. I then verified that the brake lights did not come on. This told me it was either a fuse or a very difficult to remove and find a replacement for brake switch.

Solution:
I used the below video to determine the stereo and steering control system are both routed through the 10a Gauge fuse. I removed the fuse and verified it had a visible break. Upon replacing this fuse all issues were solved.
