Though some would like to know some of the issues we have after 2.5 weeks and 1500 miles. 75D, premium upgrades, auto pilot. 20 inch wheels. Problems noticed thus far. 1. There is a creaking sound from the left front wheel area when backing up and turning to the right, especially when it is hot outside. 2. The driver door speaker is muffled, distorted and low volume. 3. Passenger door window has a knocking sound when it winds up. 4. The second row seat on the drivers side doesn't always return to normal and shows on the screen that it needs to go back further. 5. Relatively small issue, when you do the Xmas show the driver window rarely winds down. I will be going into service but honestly I have been delaying because they wan't to give us a loaner Infinity or Mercedes. I don't want to drive them so soon after getting the X. I am likely going to wait a little longer to take it in. Other than these items the Car if perfect.
