2.4L in my 2011 200 and my wife's 2012 200 have been GREAT. 106K miles and 76K miles, respectively. Neither leaks a drop of any fluid, and neither uses more than 1/2 qt of oil in 4,000 miles between changes. Plenty of power for these cars, only noisy when you get on the throttle. And that's mostly because the automatic kicks down to too low a gear, RPMs sometimes hit 5000 just to accelerate moderately onto the highway.
