Other Fuel System Fuel Gauge problems of the 2004 Chevrolet Venture

We bought the van used from a dealership about a year ago. The van was fine at first but a couple of months after we bought the van the fuel gauge fluctuated. The fuel gauge was at half, it went to empty then full and back to half, all in one motion. I thought it was odd but never had a fuel gauge do that to me before. After that the fuel gauge would fluctuate periodically but would always go back to were it was before it fluctuated. We figured as long as it went back to were it was before it fluctuated then we would just deal with it. Boy, were we stupid for thinking that it wasn't going to get worse. It eventually got worse and now it reads full(but its not) and just out of nowhere goes to empty and the fuel light comes on. Just last week the fuel gauge read empty, we put $50 worth of fuel in the van. The gauge read full, we did some running around town(we live in a small town) so we couldn't have used much fuel. We went home and was going to leave again a few hours later and when we started the van and got down the road, the fuel gauge went to empty immediately. Its frustrating that the fuel gauge doesn't display correctly. My wife usually drives the van and I don't want her to run out of gas and get stranded somewhere. I've been reading a lot about this problem on the internet and I was just wondering how many people does it have to affect to warrant a recall by gm? does someone have to get hurt or killed before something gets done? have always bought gm vehicles(never had any issues) but it doesn't make any sense if gm knew about the problem and decided to do nothing. Now were stuck paying 3 more years on a van that doesn't operate properly. We don't have the money to trade it in for something else and don't have the money to get it fixed. Very frustrating!.
