Flywheel broke. Newer "dual mass" type flywheel is very expensive ($1000) but was covered under warranty along with labor ($350). Failure damaged the clutch and pressure plate which were not covered ($350). Clutch pressure plate! I drive 95% freeway miles - hardly any shifting. 
65000 mi Finally after 6.5 years and 65,000 miles, the first non-maintenance repair -- a split CV joint boot. Shop spotted a small hole in the other and replaced it, too. Work done under warranty.
