Tesla rear camber arms (see the photo silver colored) fail due to the heavy battery load and will incur substantial negative camber angle causing severe inner tire wear and potential blow out of rear tires and causing accident and injury. Those camber arms are not adjustable as designed by Tesla on all vehicles of Model S, 3, X and Y on all vehicle years. This is a design flaw that Tesla was made aware of but they are reluctant to fix it. Also, if we as consumers fix this issue with an aftermarket adjustable camber arms (blue in color in the photo), Tesla would not do the wheel alignment.
