I have a new to me 2012 rav4 base. On first start up of the day in a cold or warm climate I start it and makes a loud muffler noise (Muffler was replaced). Not the noise that on the Youtube videos that terrible sounding. It's more or a roar sound then idles fine. Any ideas or is that just how it is? Does ur Rav4 sound like that on first start? Second is when putting it in drive or reverse it tends to slam into gear again only on first start up of the day. All these goes away after warmed up. I think I'm over thinking just want some input.. Plus I brought it into Toyota last week they said it was okay checked out fine. also anyway to turn off the chime the dealer wouldn't do it for me.... Thanks!!!
