Tough question, many factors in play: The force(s) distributed to the shock tower are highly variable - There are what, 4/5 combinations of model trim with different wheel/tire combinations and effective damping rates (not to mention jacking forces, road conditions etc, etc).
With Zillon collating the data, one would expect to see definitive patterns that greatly narrow down the probability of each model/equipment group experiencing the issue.
