Have brought car twice for vibration and shutter when vehicle is driven on highway. The shutter is extreme and only stops when car comes to a dead stop at an intersection or toll. Increasing speed or lowering speed does not stop the extreme shutter felt in wheel and passenger compartment. Car has only 37,000 miles on odometer! This extreme vibration and shutter is intermittent and not all the time.This problem has been previously reported to NHTSA as propeller shaft front head on AWD system. Portland Volvo has done alignment on 10/10/22, but could not find reason for shutter/shimmy. Brought car back to dealer on 10/27/22 and they found nothing. Bringing car back to dealer on 11/16/22 for same problem.
