WHEN USING THE DRIVER'S SIDE FRONT SEAT BELT ON MY DAUGHTER'S CAR ON FRIDAY, 11/13/2020, THE METAL BELT CLIP CLICKS INTO THE BUCKLE WITH AN AUDIBLE CLICK. THIS APPEARS TO BE SAFELY ENGAGED, YET IF I TUG ON THE BELT, THE CLIP POPS OUT OF THE BUCKLE. I TRIED THIS REPEATEDLY AND HAD THE SAME EXPERIENCE EACH TIME. MY DAUGHTER TOLD ME THIS HAD BEEN OCCURRING FOR SEVERAL WEEKS. REALIZING THIS IS A SERIOUS SAFETY HAZARD THAT NEEDS TO BE ADDRESSED, I CALLED THE GM DEALER FOR HELP. THEY TOLD ME THE BUCKLE ASSEMBLY IS NO LONGER AVAILABLE TO BE REPLACED. I THEN CALLED GM DIRECTLY TO SEE ABOUT GETTING THIS PART AND TO REPORT THE SERIOUSNESS OF THIS SAFETY CONCERN. THEY CREATED A SERVICE REQUEST CASE NUMBER 9-6357435144. THEY IN TURN DIRECTED ME BACK TO THE DEALER I ORIGINALLY CALLED. THE DEALER'S SERVICE TECHNICIAN THEN SUGGESTED I GET A USED BELT BUCKLE FROM A JUNKYARD. I CALLED GM AGAIN AND THEY ATTEMPTED TO DIRECT ME AGAIN BACK TO THE ORIGINAL DEALER I HAD CALLED AND THEY CONNECTED ME TO PREVIOUSLY. WHEN I TOLD THEM I NEEDED TO HAVE THEM FIND THIS PART FOR ME, THEY SIMPLY DIRECTED ME TO ANOTHER NEARBY DEALER. WHEN SPEAKING TO THIS DEALER, THEY DID NOT HAVE THE BUCKLE ASSEMBLY ALSO, BUT WERE ABLE TO LOCATE OTHER DEALERS THAT HAD IT. IT WILL TAKE A WEEK FOR THIS PART TO ARRIVE. IN THE MEANTIME, MY DAUGHTER IS DRIVING IN THE TWIN CITIES WITHOUT A SEAT BELT AS IT IS DEFECTIVE. I PRAY SHE DOES NOT GET IN AN ACCIDENT AS IT IS WINTER IN MINNESOTA. PLEASE NOTIFY OTHER OWNERS OF THIS MODEL CAR THAT THEY MAY HAVE A SIMILAR BAD EXPERIENCE AND NOTIFY GM TO TAKE THIS PROBLEM MORE SERIOUSLY THAN THEY HAVE WITH ME SO FAR. RESPECTFULLY, GLEN WOLF
