it varies.
My mother notices things on her own vehicle, my sister in law does not.
I worked on my sister in laws car awhile back, was just doing a simple oil change and when I was finished and was going to take it back to them I didn't even make it a half a mile before I turned around because one of the front wheel bearings was howling so bad it sounded like a plane taking off.
in the midst of taking that apart I also noticed the brake pads getting low and a caliper was leaking, sometimes things just cascade to other problems
