NHTSA Complaint #11613526 — 2017 TOYOTA CAMRY

My Toyota Camry SE 2017 while driving on freeway, my car started to smell like something burning few minutes later the car radio and lighting started to go crazy on off flashing randomly. going on off random screens by itself. i tried turning radio off but it wouldn't let me. when car turnkey is on without running the warning lights says check charging system. dealer says not sure why it says that but nothing wrong i replaced a battery already bottom half radio doesn't work. cranking sound in steering wheel prior to this about 5months replaced arm controls. Replaced axles my radio still has a issue working and my headlights keep burning out my air bag lights stay on when someone is in front seat or not in seat there for not properly working. wheel is really loose feeling
