I noticed swollen lug nuts on my 2017 Ford Mustang GT350 after less than two years at 10,900 miles when I was performing a periodic torque check and couldn't get the correct 21mm socket onto several of the lug nuts. The Ford dealer service representative told me this was a common problem with the two-piece aluminum-over-steel design, and replaced the swollen lug nuts under warranty. Fortunately, I caught this issue before the lug nuts had swollen enough that a 22mm socket would not work. I understand one of the class-action lawsuits was thrown out because there was no evidence presented that the issue had occurred (i.e., problem documented and corrected under warranty), so Ford was "unaware" of the issue. I would be that example. I plan to replace the OEM lug nuts with after-market McGard one-piece lug nuts to ensure I don't have to pay for expensive removal and replacement at some time in the future.
