Problems with 2010 Toyota Venza STEERING

There is a rattle in the steering column when turning it on uneven roads. also, the drivers seat smells like it's burning when the seat heater is on.

The electrical in my car flickers off and on the dome lights my headlights my license plate lights flicker off and on all the time now my driver visor light will not come on when i am driving in motion i can hear sometimes they squeaking noise sometimes i grinding noise and i feel like my car is going all over the place my tires are being worn out way more than they should i was told my struts were leaking and then i was told i would they were not i don't know but at times i do not feel safe driving in this car and for some reason i have to keep changing my brakes almost every 5 months 6 months or so they need to be checked because my brakes will feel like they are going out but i do have brake pads on them still but in order for my car not to make certain noises or drive sometimes a certain way i need to put brand new pads on even though i have new pads on already
