Call your dealer. They were the only ones who could tell me that, YES, my VIN out of a whopping 9500 or so affected vehicles fell in the range. It can't be fixed anytime soon, either, because they don't have the parts thanks to the damned corona virus and the plant being shut down. Mid-July at the earliest and it's UNSAFE to drive. Thanks, Toyota...
EDITED.........Using The F word here is a great way to get booted out. Don't do it again.
So just like the engine block issue, I can't believe all of the control arms are made in the same plant with the same material. Unless the wrong material was called out on the spec sheet, then they can all be bad.
Mine was made in Japan so I wonder if that will make a difference.
