I recently noticed several problems with my 2019 Diesel Land cruiser J150 (called Prado elsewhere):

 - When I go straight and let go of the steering it goes left fairly hard, have to constantly apply pressure to keep it centered
 - When I am going exactly straight, the steering wheel is actually at a noticeable right angle 
 - When I go >40kmh, It starts rattling. Rattling at 80kmh is sometimes very intense

I bought this car brand new and haven't changed the AT tires yet, It's now at 70k km. I have used these tires year round. 

I guess the rattling will go away after changing tires?

Which services should I get given this situation? 

Is this something that just has to be adjusted every couple of years, or is this something that might be warranty related?

How urgently should I fix this?

I don't remember hitting anything hard, curbs here and there has definitely happened. Once at speed. 

My Land cruiser has the hydraulics package, not sure if this is relevant.
