Started acting erratic at 80K miles. At 130K miles now. I knew of this issue when I had a 00 Pontiac Bonneville. Its an issue of cost cutting on GM design and the floater failing. Does Not cause any harm and I've learned my car. Also Now I go by the millage to when I need to fill up.
On and off so I have to keep it close to full and I track it by my odometer to make sure I have enough fuel.
