NHTSA Complaint #11113563 — 2017 CHEVROLET SILVERADO

THIS VEHICLE, LIKE MANY OTHERS OF THIS SAME DESIGN, HAS HAD A VIBRATION AT HIGHWAY SPEEDS SINCE THE VEHICLE WAS PURCHASE ON 9-14-2017. IT HAS BEEN ADDRESSED BY THE DEALER FOUR TIMES WITH THE TIRES BEING THE PRESUMED ISSUE. THE VIBRATION HAS CONTINUED EVEN AFTER DIFFERENT TIRES INSTALLED AND RECENTLY THE VIBRATION CAUSED THE VEHICLE TO BEGIN TO DRIFT TOWARD THE EDGE OF THE ROADWAY WHILE TRAVELLING AT 70 MPH IN A 70 MPH SPEED ZONE IN A CURVE THAT WAS NOT POSTED WITH A REDUCED SUGGESTED SPEED. THE TRUCK HAS CURRENTLY BEEN AT THE GENERAL MOTORS DEALER IN DELAWARE OHIO FOR EIGHT DAYS WHERE THEY HAVE VERIFIED THE ISSUE, HAVE NOT BEEN ABLE TO LOCATE A CAUSE AND HAVE NOTIFIED GENERAL MOTORS FOR GUIDANCE. WHILE RESEARCHING THIS ISSUE I HAVE FOUND THAT IT APPEARS TO BE A LONG TERM ISSUE FOR THIS MANUFACTURER THAT IS NOT BEING ADDRESSED. BEING A RETIRED STATE TROOPER WHO HAS DRIVEN MANY MANY MILES IN HIS CAREER, I FEEL THIS SITUATION COULD CAUSE A SERIOUS SAFETY ISSUE THAT COULD POTENTIALLY CAUSE A LOSS OF CONTROL AND CONTRIBUTE TO INJURIES OR WORSE TO THE VEHICLE OCCUPANTS. PERSONNEL AT THE DEALERSHIP HAVE CONFIRMED TO ME THAT THEY HAVE HEARD OF THIS SITUATION AND THAT SOME TRUCKS ARE ABSOLUTELY PERFECT WHILE OTHERS DEVELOP THIS CONTINUING PROBLEM. THIS VIBRATION BEGINS AT APPROXIMATELY 68 MPH AND CONTINUES TO AT LEAST 76 MPH AND IS FELT THROUGH THE SEAT, ACCELERATOR AND STEERING WHEEL. I DO HAVE SOME OF THE "REPAIR" DOCUMENTS BUT THEY ARE INCOMPLETE AT THIS TIME.
