NHTSA Complaint #11290832 — 2019 RAM 1500

THIS INCIDENT HAS BECOME MORE PREVALENT. IT BEGAN ABOUT TWO MONTHS AGO AS WHAT I THOUGHT WAS SOMETHING STUCK IN THE GROOVES OF THE TIRES. BUT AS IT BEGAN TO OCCUR MORE AND MORE REGULARLY I FELT IT WAS TIME TO TRY AND GET SOME HELP WITH THE PROBLEM. WHILE IN MOTION, WHEN I REMOVE MY FOOT FROM THE GAS PEDAL AND IT IS NOT PRESSED AND TRUCK BEGINS DECELERATING, AT APPROXIMATELY 45 TO 50 MILES PER HOUR A DRONE/HUM WILL BEGIN WITHIN THE CAB OF THE TRUCK. IF I DO NOT PRESS THE GAS PEDAL OR ROLL DOWN WINDOWS THE DRONE/HUM WILL GET LOUDER AND MORE PRONOUNCED. IF IT IS NOT ELIMINATED, THE DRONE/HUM WILL INCREASE IN DECIBELS AND ACTUALLY BECOME PHYSICALLY FELT WITHIN THE TRUCK. SINCE THE SOUND ALMOST SEEMS TO RESONATE FROM THE SPEAKERS, I HAVE TRIED UNPLUGGING THE ANC (ACTIVE NOISE CANCELLATION) DEVICE UNDER THE DRIVER'S SEAT. WHILE THIS DOES STOP THE RADIO SPEAKERS FROM PLAYING ANY MUSIC, IT DOES ALSO SEEM TO PREVENT THE DRONE/HUM FROM OCCURRING. THE TRUCK WAS PURCHASED IN EARLY JUNE OF 2019 AND CURRENTLY HAS ABOUT 12,500 MILES ON IT. THERE HAS BEEN NO CUSTOMIZATION OR ALTERATION OF ANYTHING ON THE VEHICLE.
