More additions:

Engine:

-- Late-08/early-09 bearing failures (this was a stop-sale recall item, and usually happened at pretty low mileages)
-- 07-08? intake manifold gaskets can leak, causing rough idle
-- Bearings may fail if turbo fails and engine is run with contaminated oil

Turbo/intake/exhaust:

-- VF40 turbo (05-06) is a common failure point
-- Both VF40 (05-06) and VF46 (07-09) can fail due to clogged banjo bolt filter and/or stuck oil control valve (OCV)
-- 05-06 catted up-pipe cat can break up and destroy turbo
-- Stock TMIC end tanks can separate at greater-than-stock boost levels
-- Turbo inlet tears easily when working around turbo, so may need to be replaced

-- Transmission/driveline/suspension:

-- 5MT 5th gear can break; other problems with 5MT on occasion
-- 5MT and 6MT transfer shaft bearings (the new bearings use a revised design)
-- 5EAT often cannot handle power levels significantly above stock
-- Rear wheel bearings (extended warranty up to 100k mi on 05 and early 06)
-- Front right axle boots can fail due to heat from turbo/exhaust
-- LCA and sway bar bushings wear out

Other:

-- Driver's window switch sticks (occurs mainly on 05s, but may become an issue on other years as the cars accumulate miles)
-- Headlight bulbs fail early and often
