Front Seat Belt Buckle Assembly problems of the 2003 Chevrolet Tahoe

My wife's 2003 Chevrolet Tahoe has a latching problem with the front drivers seat belt. Frequently the seat belt will not latch. It takes multiple attempts (as many as 6 or 7 attempts) to get the seat belt to finally latch. While this component has not completely failed yet, the likelihood of a complete failure appears probable. This component is a critical safety feature on automobiles and it's failure would probably result in death if the vehicle was in an accident while the seat belt was unlatched. The component is not something that should be subject to failure due to normal usage. The vehicle has 80000 miles on it. I have not reported this to my dealer yet. The obvious critical nature of the component led me to report this to you so that you may investigate if more people are experiencing the same problem. In 34 years of driving, I have never had a seat belt that would not latch including on my 36 year old gto.
