My Qx70 3.0D had this same noise which ended up being under tensioned wheel spacers (H&R bolt-on). However it can also be caused as per the infiniti service bulletin found at https://static.nhtsa.gov/odi/tsbs/2020/MC-10171195-0001.pdfi am having the same noise. i thought it was maybe more toward the rear end. not sure what it is but would like to pinpoint if anyone has dealt with this
