Perfectlap, you are no doubt correct that the numbers are incomplete and therefore undereported, but I would not refer to them as the 'tip of the iceberg'. Porsche's numbers include all cases which ended up at a Porsche dealership (or with a claim or request for coverage after the expiry of the warranty period), regardless of age and mileage. Did some people not take it to the Porsche dealership after failure, or even try to get something out of Porsche? No doubt. But most people would have done one, or both (and there are certainly reported cases where Porsche provided full or partial coverage after the warranty expired - albeit, typically only for those who purchased the car new). So if an additional 25% or even 50% of failures never came to Porsche's attention, it takes 'much less than 1%' to what - maybe 1%? You're right, however, that a 25 - 50% increase on the published numbers for the single-row bearing would make a bad situation worse - ie, if 50%, then 8 - 12% becomes 12 - 15% Still unlikely, but.....
