Are there are any structural or materials engineers on this thread?
I ask if they might, perhaps, use their professional expertise to analyze some of the far too many failed control arms and report back?
Since Elon is an engineer, he should just look at the facts and demand a recall, even if Tesla is not, necessarily, required to do so by NHTSA or other organizations. It just seems like a prudent course of action, and the cost would be borne by the supplier since I doubt Tesla was making these internally back in 2012-2014.
This falls into the "no-brainer" category of things Tesla needs to do. Yesterday.
While it MIGHT have just been pure coincidence, sending out what is certainly (despite embarrassing language to the opposite) a safety-related, safety-critical, TSB after the affected cars were out of warranty is just wrong. Ethically, morally, and totally WRONG.
Elon: FIX THIS!
(This is such a glaring example of an otherwise brilliant company, filled with many smart people, doing a remarkably stupid thing. Tesla: NOT wait until someone is hurt of killed. If you wait wait long enough, that's probably going to happen. I can only imagine what the publicity, and settlement cost, would look like. We can all pity the attorney trying to defend that utter BS language in the TSB in front of a judge or jury . . . . )
