So, I noticed there was a grinding noise that lasted about 1-2 seconds on start up for about a month and a half, the car is at 27xxx miles so not very "old" at all. I thought maybe it was from cold-starting, I park my car in the garage, but it still gets cold enough when I get to my car around 630 and I hear it every so often when I have to go to lunch or home. Took it in to the dealer and apparently it's coming from the muffler. Yesterday I took it in after the part came in earlier in the week and when I got it back all is well and my MPG and throttle response shot up.

When looking through the service invoice(no cost due to warranty) it stated that the muffler was coming apart from the inside out. Anybody ever have this issue or was there a recall that went out and I simply never got it???
