P0300 - Random/Multiple Cylinder Misfire Detected
P0302 - Cylinder 2 Misfire Detected
P0312 - Cylinder 12 Misfire Detected

I don't show a listing for code 316, and I really doubt you have a 12 cylinder engine! The most common cause of misfires is spark plugs, and spark plug wires and / or ignition coils, depending on which engine you have. Start with those if they haven't been replaced in a long time.

Thank you. I have warranty on the car as I just bought it 10 back from a car dealer. I am planning to get this checked out and will post back results soon for everyone else knowledge.

Thank you again for the quick response.
