A good read.

You have 1 of two things happening:

1) You haven't put a good enough seal from the pump nozzle to the filler hole to create a pressure seal, not allowing the gas to build up to trigger the auto shut-off.

2) You have a leak somewhere in your tank or filler neck causing air to escape. Do you ever get a check engine light? A leak is possible, however unlikely, due to the sensitivity of auto shut-offs, and the massive leak necessary to render them ineffective. That and a fuel leak in your tank would drive your sensors crazy, giving you constant check engine lights.
