Isn't there a chance of the issue being temporary, is it 100% permanent and will die soon?
There is always a "chance".
Unlikely, though.
You have a car tire with a slow leak.
You go out in the morning, it is flat.
You get your little pumper thing, and pump it up.
Is it fixed? No.
But it looks just fine, and IS driveable for a few days.
But, a few days days from now, it will go flat again.
This may be while you're driving at 70mph, in the rain.
Leading to loss of control, a spin, a rollover, and everyone dies.
Or, you could replace the faulty tire.
