the one year I've owned this car, I've had so many crazy sounds coming from under the hood, sometimes when you start it up, you hear a loud rattly sound which sounds like bent valves, but if you give it a little gas.. it goes away. and when you press on the gas, you hear an annoying clicking sound coming from the passenger side of the engine. as soon as you turn the AC, the engine misfires, idles rough, and the clicking sound from the right side of the engine gets much worse.

Kept maintenance up to date, and nothing has fixed these sounds.
