I've noticed this the last couple of days. I went for a drive, everything "felt" ok, but the noise remains. It seems to start after I rev the engine... Any ideas? Thanks.

that is strange, sorry I have no idea...

 

Exhaust leak?

 

Doesn't sound like an exhaust leak to me... that's hard parts hitting each other, that, or he got the popcorn maker option.

I am no expert... but I once had an inline 6 on a 1978 Camaro that made a similar noise... turned out to be a loose rocker arm.

 

I agree sounds like hard parts hitting but it isn't consistent. Maybe a loose piece of plastic hitting a cooling fan?

 

yikes, hope it's not a bearing. please provide an update once you find out!

 

Thanks for the help guys. I took her into the dealership over the weekend and so far that haven't found the issue. They are going to spend some more time on it in the morning. I'll let you know what happens... Glad I have the warranty! Hopefully it's something minor.

 

Grimlin with a small hammer?

you've got a lazy or cracked coil pack. if it continues to deteriorate the car will misfire tripping the cel. diy on these are a ***** on your back. save yourself the time and have the dealer replace. while you're in there----do the plugs too.

 

I left the car at the dealership for two days and they were not able to duplicate the issue. I showed them the video as well and tried to duplicate it myself... The 3 days prior to bringing it in this was happening every time I started the car. So the mystery continues.
