NHTSA Complaint #10918774 — 2016 CHEVROLET SILVERADO 1500

I AM HAVING AN ISSUE WITH MY NEW 2016 SILVERADO AND A VIBRATION AT HIGHWAY SPEEDS. I TOOK THE TRUCK BACK TO THE DEALER WHERE IT WAS PURCHASED WITH AROUND 340 MILES ON IT. I WAS TOLD THEY COULD DO NOTHING UNTIL I HAD 1000 MILES ON THE TRUCK (THEY STATED THEY COULD NOT GET PAID BY CHEVY FOR WARRANTY ITEMS). THAT TICKET STATED THEY REBALANCED MY TIRES. THIS HAD NO CHANGE. I TOOK THE TRUCK BACK AFTER 1000 MILES. THE DEALER DID A ROAD FORCE BALANCE. THIS HELPED VERY LITTLE. NOW, AT 1345 MILES, IT IS BACK IN THE SHOP. THEY STATE THEY WILL DO A PICOSCOPE ON THE TRUCK AND CHECK THE AXLE. I SHOULD MENTION THE UNDERLYING ISSUE IS A VIBRATION THAT CAN BE FELT AT SPEEDS IN EXCESS OF 65-70MPH. IT IS MORE PREVALENT FROM 70-75MPH. I HAVE FILED A COMPLAINT WITH GM, REFERENCE CASE 82405350103. THIS APPEARS TO BE THE SAME ISSUE FOR THE 2014-2015 MODELS REFERRED TO AS THE "CHEVY SHAKE". ONE MORE ATTEMPT AND I WILL LIKELY START LEMON LAW PROCEDURES IN GA. I WOULD LIKE SOMEONE TO SERIOUSLY INVESTIGATE GM ON THIS COMPLAINT. THERE ARE PLENTY OF FORUMS WITH PEOPLE COMPLAINING ABOUT THE SAME ISSUE. THIS COULD BE AN EXTREMELY DANGEROUS ISSUE IF IT IS TIRE OR WHEEL RELATED, OR EVEN DRIVE SHAFT RELATED. *TR
