On august 27, 2019, i purchased a 2020 bmw x7. since purchasing the vehicle, it's been returned for repairs at two authorized dealers at least two times and spends two weeks of my 2 months ownership in the service. according to the authorized dealer, the defects affecting the vehicle and creating unpleasant, whistling noise is due to the design of the vehicle. it is too much money for a vehicle that gives me headaches.
