NHTSA Complaint #11489367 — 2021 HYUNDAI SANTA FE HYBRID

Having issues with the dash going completely black; so you can not see any instruments on the dash panel or the head unit (navigation/radio/airplay). The car has been into the shop three times so far with no resolution. The newest issue; the horn doesn't work, the safety features such as lane assist, lane departure etc. only work intermittently, and I have had the brakes slam on for no reason. The last time I took the car back to dealer and told them I was afraid to drive the car, the service manager changed the settings on the safety features, not sure how that was to fix anything? We have been so close to being rear-ended because of the faulty braking system. The electrical system is having major issues, I have videos of the car doing all these things and have showed them to the dealership and they claim they can not fix the car because it doesn't happen when they drive the car.
