I’ve never had an issue in 2+ decades, I have T-shirts that are 10 years old and still in good shape. What really kills clothes is the dryer, I try to line dry everything for that reason.

And the only washing machine I’ve had to replace was due to an electronics failure, the seals were fine 😊

Ordinary white vinegar is good for a lot of things, but it’s too dilute to use as a fabric softener or limescale prevention.

I’ve used acetic acid (32%) for decades, 30ml or so per wash. It’s even listed right on the bottle that it works as a fabric softener, keeps colors from fading and prevents limescale buildup.

And it goes in the fabric softener compartment of course, if you mix it with the detergent the acidity will reduce its washing power(detergent is alkaline).
