I'm not so sure... While certainly
any mechanical part can fail, and a relative few early cars suffered IMS failure, it seems to have become an 'issue' with the later ('03-?) cars. A sampling of the various forums will probably bear this out.
As far as 20% being the failure rate, I doubt this (at least with the avg. mileage of the boxster 'fleet' to-date), that sounds more like the RMS failure rate.
