Tailgate problems of the 2003 Chevrolet Suburban

I noticed a sound like that from an open window and check all driver and passenger windows verifying that they were closed. Upon utilization of the rear hatch, it was noted that one of the two (50%) latches that hold the rear window/door to the car had separated. I brought it to Chevrolet dealer at the time and was told there was nothing they could do. They did not consider the doors as required or this to be a safety issue. At the time, I found 1000's of people online complaining about the same issue. I'm sure that this has increased 10 fold since then. I only use this car as a 2nd car now and do not utilize it daily. I fear that the 2nd rear window/door latch will also fail and cause the entire window/door to separate from the vehicle thus landing on the highway behind me (hopefully) or on the poor family in the vehicle behind me (worse case). Unfortunately, I live in the washington DC area where people like to tailgate. Traveling on highways with the wind rushing through the window causing additional stress on the latch make the later scenario more deadly and more of a reality. Gm/Chevrolet should fix what seems to me as a minor repair to ensure the safety of the general public why hasn't this been addressed if so many people are having issues with the latch?.
