Other Fuel System Pump problems of the 2004 Buick Lesabre

I've owned 5 Buick Lesabres, and continue to run two of them (2002 Lesabre with about 180,000 miles, and 2004 Lesabre with over 80,000 miles VIN: [xxx] for the 2004, and [xxx] for the 2002). Both currently owned Lesabres have fuel gauge problems. My 2002 showed erratic inaccurate readings, but now is flatlined at empty, even if the tank has just been filled. My 2004 is showing the opposite reaction, showing full, even after a full trip should be sending it toward an empty reading. Something similar happened on a previous Lesabre I owned, and cost me a new fuel pump & gauge running nearly $500. This is obviously a common occurrence if I've had it occur on 3 of five Lesabres I've owned. It's also a very common complaint on the internet. Just recently on the 2002, I ran out of gas in the middle of heavy traffic due to gas gauge inaccuracy. Fortunately it was a low speed region. However, had I run out of gas in rush hour traffic surrounded by 18 wheelers, this could have lead to traumatic injury or death. 1 failure . . . I could tolerate, and was willing to pay for it without complaint . . . . . But 3 out of 5 Lesabres !!!???? that's a design defect or manufacturing defect. I am seeking a recall on Buick Lesabre gas gauge units information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).
