Electrical System problem #1

I am not sure this qualifies but I will submit the problem. All of a sudden, the center console display disappeared. Besides showing the radio tuner, it provides access to the gps, cell phone connection and other devices. It also provides access to the backup camera which does light up when put in reverse. The cell phone connection provides hands free use of the phone which comes in handy during an emergency.

Electrical System problem #2

When turning the steering wheel several things happen. Channels change, phone hangs up, gps stops, air bag light comes on. Dealership inspected and said need to change spiral cable. $1200 dollars.

Electrical System problem #3

I purchased a 2022 Toyota 4runner and 9 days later the wiring harness was destroyed by rodents most like squirrels. Toyota switched to soy based wire insulation without taking precautions in the design to protect the wiring from rodents attracted to the insulation material. The resulting damage cost $8000 to repair and it will take months for the harness to be in stock. This failure caused all safety features to be disabled leaving the vehicle without standard safety functions.
