2014 Kia Optima Ex
Hi everyone. My Optima has developed a knocking sound when at a stop when brake applied. It only happens in drive and reverse. When put in neutral or park it goes away. Also if in drive and i put the emergency brake on it goes away. If the emergency brake is on and it is in drive the knock will start again when brake is applied. It only does it after the car has warmed up after driving for an extended period. Car runs and shifts fine and does not make the noise while accelerating... New plugs, oil change and transmission drain and fill...Thanks for any help you can give.
