NHTSA Complaint #10251260 — 2007 GMC SIERRA 1500

I HAVE A 2007 SIERRA,WHICH HAS BEEN GIVING ME PROBLEMS SINCE IT WAS PUR CHASED. IT HAS STOP IN THE MIDDLE OF THE TRAFFIC WHEN I WAS DRIVING. IT HAS DONE THIS 4 TIMES SINCE I PURCHASED THE VEHICLE. I HAVE TAKING THE VEHICLE TO THE DEALER, BUT, THEY NEVER FIND ANYTHING WRONG. ON SATURDAY THE CAR STOP , IN THE MIDDLE OF TRAFFIC, AND THIS TIME IT DID NOT MOVE AT ALL. THE TRUCK WOULD NOT MOVE, AND I WAS TRYING TO MAKE A RIGHT, BUT I WAS STUCK. I WAS WORRIED THAT SOMEONE COULD CRUSH FROM THE BACK, BECAUSE THEY COULD NOT PASS, THERE WAS A MAN THAT CAME AND PUSH MY TRUCK TO GET OUT OF THE STREET .AND NOW I AM CONCERNED FOR THE SAFETY OF MY DAUGHTER AND ME. THIS VEHICLE HAS GIVING ME MANY PROBLEMS, BUT THE DEALER NEVER SEEMS TO FIND ANYTHING WRONG WITH THE VEHICLE. I HAD SOME ITEMS INSTALLED BY THEM. ONE WAS A DVD PLAYER, IT COST 2,300. AND THEY SAID THAT IT WAS MY FAULT SO THEY DID NOT FIX IT. AND THAT WAS 3 MOTHS AFTER THE INSTALLATION OF THE DVD BY THEM. AND THE BATTERY DIE ON THE TRUCK 4 MONTHS AFTER IT WAS PURCHASED. THAT WAS THE ONLY THING THEY CHANGE. I HOPE THAT I CAN BE HELPED, I FEEL VERY INSECURE IN THIS VEHICLE. I'M HAPPY THAT I DID NOT GET INTO A MAJOR ACCIDENT BECAUSE OF ALL THESE PROBLEMS. THANK YOU . *TR
