Exhaust manifold is notorious for cracking. Although mine hasn't yet, it's pretty much a given that it will soon. Everyone's does. Mildly expensive to repair ~$500.
The AC compressor is notoriously unreliable. I've needed to replace mine twice. Mildly expensive to repair ~$600.
The radiator has been replaced twice. Mildly cheap to repair ~$300.
Although built well, the engine and transmission have a few reoccurring leaks.
The engine gets extremely hot and over time can make removal of old spark plugs, hardened wires, bolts etc. very difficult.
Brake rotors have warped.
Various interior electrical components have ceased to work.
Paint is slightly faded and a small area has begun to peel.
