Almost all problems afflict models before 2006, as design flaws were corrected later. Brake judder, caused by rotors or calipers and steering gear, may require updated replacement parts. Noisy fan clutch  should be replaced by updated new one. Chirping or squealing from the engine comportment is due to serpentine drive belt, fixed by updated replacement belt. The limited slip differential may chatter on slow turns, for which there are improved clutch packs. Vibrations at highway speeds in the floor or steering wheel may be corrected by installation of a frame-mounted damper kit. Insignificant random problems, such as vacuum-line leaks and slow power windows.
