We have had our MX for almost two weeks and absolutely love it, but wanted to see if anyone else had run into this issue. Randomly, sometimes, this feature will emit a loud noise over the speakers....almost like an airplane flying over head. The other day, it emitted a loud high pitched noise like two microphones being in the same vicinity together. We can immediately get it to stop by rolling the window down, opening the door, or turning off the feature. This makes sense as it states that in the manual. Has anyone had this occur and found a fix for it? When it works, it works rather well.... something something tesla, I know.
