Talked to service department on May 20 2020 over the telephone that the speedometer was not measuring the true MPH with an error speed reading between 10 to 15 miles per hour when driving the car. Our son observed suddenly the problem that we did not notice, we that it was related to break-in period but the problem continues after many months. The Service department said that was a first, never heard of the problem so they setup a appointment for May 26 2020 to check the car. We will inform on the results about the problem later.
