Rob Maurer covered this in Friday's edition of "Tesla Daily" on Youtube. The number of S/X affected in China is 0.1% of 30K units, or exactly 30 cars. Call it $1K wholesale to replace the front half-shafts, and that's $30K total. Peanuts (unless ur short).
In the U.S. the affected rate is 0.05% but their is NO recall. That's why Tesla says the issue doesn't justify a recall in China, but it's more expensvie to appeal the ruling than to just update the 30 cars listed.
The S/X isn't sold globally, but I think that Bjorn broke his half-shafts hooning offroad in his (referral freebee) Ludicrous Model X "
Optimus Prime"
Cheers!
