Mine is on 3rd drive unit, now at 125k miles, all replaced under warranty. First one was about 2016-2017 making a high pitched whine. 2nd one replaced in late 2020 while still under warranty. It was making a loud metallic thunk on starts, occasionally on regen. Within a week or two on the new one, noise started again and has been there ever since. At no point were there any other performance or drive quality issues. If I had plans for keeping the car longer, I would probably worry about it more but it seems to have been a stable problem for at least a year now.
