Blend door actuator. Turn on and cycle the HVAC system and see if you hear a constant clocking noise. Not terrible, just a plastic gear that breaks. Well documented on the forums.
Check the rear arches, antennae, and jams/where the sheetmetal is rolled over (like door skins) for rust.
Check and verify if the coolant recall has been performed.
Old coolant reservoir that was stock, pre-recall.
The resevior that's replaced with the recall and the new sensor.
Check the driveshaft boots/CV boots for tearing.
Beyond that these things are pretty much indestructible.
