My Civic Type S 2.2 has started making a constant high pitched squeal above 15mph, very intermittent. From inside it sounds like a radiator with an air lock, when you turn right it goes away. When the window is down it is really noisy, like metal on metal noise, sounds like train wheels on a train track. It gets noisier when your turn left. I know its not the brakes as I changed them a few months back and have plenty of meat left, I personally think its the EPAS motor, are there any known issues with these?
