NHTSA Complaint #10256603 — 2007 CHEVROLET SILVERADO

I TOOK MY NEW CHEVY TRUCK INTO THE DEALER FOR SOME NEW FACTORY EQUIPMENT (BUG DEFLECTOR AND BED LINER) TO BE INSTALLED BY THEM. WHILE THE DEALER HAD MY 2007 CHEVY TRUCK THEY LOADED 2008 POWER TRAIN SOFTWARE INTO IT'S COMPUTER WITHOUT MY PERMISSION. THE 2008 SOFTWARE CHANGED THE WAY MY TRUCK RUNS. THE POWER TRAIN NOW HAS A SPEED LIMITER ON IT AND THE STABILITY CONTROL WAS CHANGED. IT WILL NOT GO AS FAST IT AS USE TO GO BEFORE THE CHANGE. I WAS TOLD BY THE DEALER AND GM THEY WOULD NOT PUT MY TRUCK BACK THE WAY IT WAS AS WHEN I BOUGHT IT. THEY TOLD ME THAT THE REASON WAS THE GOODYEAR TIRES AND THE TRUCK DESIGN WERE UNSAFE WITHOUT THE 2008 SOFTWARE INSTALLED AND WOULD NOT CHANGE MY TRUCK BACK TO THE 2007 CONFIGRATION . I HAVE NOT GOTTEN ANY RECALL OR SAFETY NOTICES ABOUT THIS ISSUE. I THINK GM AND THE DEALER MADE A MISTAKE AND DO NOT WANT TO CORRECT IT. IF THERE IS A PROBLEM WITH THE TIRES (GOODYEAR WRANGLER TIRES) AND THE 2007 TRUCK DESIGN (GM SILVERADO 1500 LTS CREW CAB) GM IS TRYING TO COVER IT UP. THERE ARE HUNDREDS OF THOUSANDS OF 2007 GM TRUCKS, CARS, SUV'S EVEN CADILLAC'S THAT HAVE THE SAME POWER TRAIN IN THEM THAT MY TRUCK HAS AND THEY ARE NOT CHANGING THE COMPUTER PROGRAMS IN ALL THOSE VEHICLES. I WAS TOLD THEY WOULD BE CHANGED ONLY IF THE TRUCKS, SUV'S AND CARS WERE BROUGHT IN FOR ANY KIND OF SERVICE WORK, BUT WOULD NOT BE CHANGED IF NOT SERVICED BY GM. SENSE THERE HAVE BEEN NO RECALL NOTICES ABOUT THESE ISSUES I THINK GM IS TRYING TO COVER SOMETHING UP . THE VERY LEAST TRYING TO COVER UP THEIR DEALERS AND THERE MISTAKE BY ALTERING MY TRUCK WITHOUT MY PERMISSION OR THEY DO HAVE A SERIOUS PROBLEM THAT THE PUBLIC SHOULD BE AWARE OF. PLEASE LOOK INTO THIS. THE SAME TIRES ARE ON FORDS AND DODGES AND THEY DON'T SOFTWARE LIMIT THERE PERFORMANCE. I PAID TOP DOLLAR FOR GM'S BEST TRUCK WITH THE BIGGEST ENGINE MADE FOR IT, I COULD HAVE SAVED A LOT OF MONEY BY BUYING A SIX CYLINDER ENGINE INSTEAD OF THE BIG V-8. IF I KNEW GM WAS GOING TO DE-RATE MINE. *TR
