    Has anyone notice any cracking sounds from the wheel covers? I don't hear it when inside the car, but if my wife drives and I'm outside, one of the aero wheel covers makes cracking noise when it rolls. Its as if the cover is under excess pressure. At first it was the front driver's side wheel. I took it to service and they replaced the cover. Now its the back driver's side wheel. (I feel like they may have just swapped the covers).

    I actually do feel like when I've been in parking lots and moving slowly, I've heard crunching sounds a couple of times from the front like I ran over something brittle - which surprised me since I didn't notice anything big on the ground. And no, this was not hitting a curb or a wheel stop, just rolling slowly on level ground. Last night I got home and it looked like there was a big bulge or warping of that wheel cover, and on closer inspection it had not warped but rather had unseated on one side about 3/4". A firm slap on the part sticking out seated it firmly back in place. It didn't feel like it was loose enough to just fall off, but I wonder at highway speed whether a bump could make that happen.

    In my 35 years of driving, it's interesting that I've never owned a car with "hubcaps" or wheel covers before, even the budget cars like my 1st gen Prius with its skinny 70R14 tires were on solid one-piece wheels. I look at those random wheel covers littered on the side of highways and off-ramps and wonder what happened....

    Don't have my 3 yet, but my parents bought a Camry many years ago that had steel wheels with plastic covers and they also made some snapping noises when rolling.

    I noticed this for the first time just yesterday. I was outside when my wife arrived home and I heard a strange clicking like sound from the Model 3. I got up close and it definitely was coming from the aero wheel covers.

    Maybe that will be enough to convince my wife to go aeroless. I have the parts, but she said she likes the aero cover better. o_O

    Its the new NHTSA mandated noise maker for speeds <10 MPH, studies show the brittle sound of crushing bone (similar to the sound you describe) gets pedestrians to stop looking at their phone and look up before walking in front of you.
