NHTSA Complaint #11378168 — 2021 HYUNDAI PALISADE

I PURCHASED A PALISADE 2021 LIMITED AWD TRIM FROM A LOCAL DEALERSHIP ON 12/01/2020 NIGHT. I TEST DROVE A DIFFERENT PALISADE, BUT PURCHASED THIS SPECIFIC PALISADE AS WE WERE LOOKING FOR A BEIGE INTERIOR. WE DROVE THE NEW PALISADE FOR THE FIRST TIME ON THE HIGHWAY ON 12/06/2020. IT VIBRATES AND RUMBLES ON THE HIGHWAY. IT MOSTLY COMES FROM THE REAR SUSPICION. 1) IT CONSTANTLY SHAKES AND RUMBLES WITH CONSTANT VIBRATION 2) THE SUSPICION ALMOST FEELS LIKE SEATING ON LOOSE SPRING AND CAUSES THE LOWER PORTIONS OF THE CAR TO SHAKE UP & DOWN CONSTANTLY WITH HIGH FREQUENCY. IT MAKES EVERYONE IN THE CAR SEVERELY MOTION SICK WITH LESS THAN 50 MILES OF ROAD TRIP. IT SOUNDS LIKE PALISADE 2021 LIMITED INHERITED THE VIBRATION PROBLEM FROM PALISADE 2020 [AS DESCRIBED IN TSB # 19-SS-003H].
