The bolt/fastner holding the control arms almost backed all the way out. I was driving and heard metal sound it got worse on the drive home. I also noticed the alignment to get worse and when I got home I looked and the bolt/ fastner almost came out. There is a tesla recall for only a small percent for my year with that issue. Tesla wants 4k to replace it. It is a huge safety issue. I have a family and it could have been serious if it detached not only to me and my family but other vehicles other pedestrians.
