My 2013 SI has a sort of high pitch grind on cold start-up. Today was the first time that it happened but it is also the first cold day that I have used it ( -5 C). My rsx-s also had this sound and I could never figure out what it was. It is not a squeal like a belt, more of a grind sound and it only lasts about 1-2 seconds. Any Ideas??
