NHTSA Complaint #11329741 — 2020 VOLVO XC90

PURCHASED A NEW 2020 XC90 T6 INSCRIPTION WITH THE AIR SUSPENSION. FROM THE FIRST TIME PULLING INTO OUR DRIVEWAY, THERE WAS A DISTINCT, MUFFLED, AGGRESSIVE "THUMP" IN THE FRONT AND REAR END. THE SOUND IS INDEPENDENTLY FROM THE FRONT OR REAR SUSPENSION, DEPENDING ON WHICH IS GOING OVER A BUMP. THIS OCCURS CONSISTENTLY WHEN IN SLOW SPEEDS AND GOING OVER AN ABRUPT BUMP, SUCH AS A SPEED BUMP OR AN AGGRESSIVE CUT OUT IN A DRIVEWAY WHICH IS MADE FOR WATER RUN OFF. ONCE THE SUSPENSION COMPRESSES, THE THUMP OCCURS ON DECOMPRESSION (REBOUND). I TOOK IT INTO THE ORIGINAL DEALER (VOLVO OF TUCSON). A 2019 XC90 T8 MOMENTUM (WITH AIR SUSPENSION) WAS GIVEN AS A LOANER. AS EXPECTED, THE LOANER VEHICLE MADE THE EXACT SAME THUMP SOUND FROM THE FRONT AND REAR SUSPENSION OVER THE EXACT SAME BUMPS. THE DEALER COULD NOT REPLICATE THE SOUND ON MY CAR. I PROVIDED THEM WITH NHTSA ID #'S: 10148803 AND 10128173 (VOLVO BULLETIN #'S: TJ32978 AND TJ3303.1.1). NO RESPONSE YET AS TO THE PROBLEM OR CORRECTION. *TR
