I'm about 40mins from you in Barrie and mine does it too. Gets worse under exceleration until warmed up. I run synthetic, don't know if that has anything to do with it.I don't think it hurts them at all but have you gone to get them adjusted yet? I'm gonna, Barrie Acura quoted $100. I'd do it myself but working in this wx sux!
