On certain models the fuel gauge will not read full due to excessive resistance in the sending unit. Replacing the sending unit in the fuel tank will commonly repair this issue.

I just live with it. It seems pretty minor considering how many miles I've put on the thing.

Same as everyone else
My fuel gauge is not reading full nor moving at all.
Yet another problem my car has but I've learned to live with it, not going to repair.
