Pads and rotors. Squealer on both sides was broken off, so no warning until they'd dug into the rotors. Rears wear much faster than fronts.

Driver side vents wouldn't spit out hot air. Dealer replaced the Heater core and blend doors. Car was in the shop just over 3 weeks all told. Would have cost ~ $3500 out of pocket. Dealer I bought the car from (discovered the problem 2 days after purchase) ate the cost. As a result of the previous trip to replace the heater core, the heater core hose was torn and I discovered that courtesy of the distinct smell of hot coolant. Dealer replaced under warranty of the previous work done.

Went in for an idle issue on cold start. They changed the 12v hybrid battery. Did not solve the issue. AC Compressor was making some serious noise. Dealer found that part of the compressor "disintegrated" (their words), sending little metal shards all over. This was causing the noise, and required replacing the compressor, then doing a couple of evacuation procedures to get the metal out.
