Wanted to give everyone an update, I have 4300 miles on my car now and unfortunately have to add another issue. I now have a vibration in the clutch pedal which gets worse as rpm increases, also noticed throw out bearing noise when idling. I have used Mobil 1 and Pennzoil Ultra in the engine, valve train noise did not change and probably got slightly worse over time. Rear diff. noise did get better for a very short time when I changed out the fluid but then came back.. Very sad that in 2014 quality control can't be better!
