2022 KIA Sorento Blind Spot Safety Issues

New KIA Sorento SX Line Prestige with issues the dealership cannot resolve and the manufacturer won't authorize work on. The faults are intermittent and clear up with time, but reoccur eventually.

Faults:

- Check Side View Mirror Warning Light
- Check Left Turn Signal.

Additional faults not in this video.

- blind spot safety system turned off.
- doors won't lock or unlock.
- rear left light fast blinking

note:

after noticing the rear left blinker not working, a few taps on the light and eventually the car started later. so far this has happened 3 times. the first 2 times the vehicle was parked. the 3rd time the vehicle was being driven on the freeway when it stalled.
