Took mine in to fix my seat from coming undone underneath, the door flexing when traveling over 70mph due to air getting under the steel panel side and to replace the wiper motor. They said they fixed everything but nothing was fixed or replaced.
Why don’t they just put a couple small roller bearings at the ends that touch the tires of the originals. That way they don’t chew at the tires could be a quick $5 fix for the original wheel cover. 1-2 small wheel/baring at the end of each part that touches the tire.
Not saying it’s a good idea but if your window is cracked by debris on the highway in Florida it’s a free repair by the state just call your insurance company. I have ring cameras in my garage and driveway so if mine cracks Tesla is getting a video of it in real time lol
