Just got Infiniti 2021 QX 50, 11,700 miles. There is frequently a fairly loud thump when I change from R to Drive. Problem doesn't occur once car is up to speed, just when starting to accelerate. Thump happens from rear hatch, lower bumper or around to the right side, is usually when car has been parked overnight or for a few hours. Infiniti dealer hasn't been able to hear the thumps - but they are definitely there. It doesn't appear to be coming from the left side or the front end. I like the car but can't stand the thumping. Any help would be greatly appreciated.
