Other Fuel System Pump problems of the 2006 Buick Rainier

The fuel sensor for my 2006 Buick Rainier started to malfunction approximately two years ago. I had it diagnosed by gm dealer, king Chevrolet Buick GMC of longmont, colorado and they informed me the car needed a new fuel sensor. The fuel gauge indicates the tank is empty, when actually full. We decided not to correct the problem, due to the cost. The Buick ran out of gas numerous times throughout the last 2 years. Three days ago the car stalled on interstate 25 with passengers on board. We towed it back to king Chevrolet Buick GMC, longmont, CO. And now diagnosed with a faulty fuel pump with an estimated cost of $1400 to correct the fuel pump/sensor problem. Each time the car was diagnosed by the gm dealer, not a word was mentioned by staff/technicians about the known fuel component failure. I discovered this issue after searching the internet, yesterday. I find it hard to believe that this serious safety hazard is not publicly acknowledged by gm corp and its dealers and a recall for these vehicles has not occurred. Seems gm corp and king Chevrolet Buick GMC have no concern for consumer safety.
