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.
