The sound only happened for about half a block until I was able to park on the side of the road. I couldn't get it to reproduce the sound and I have checked the dp and the rest of the exhaust; no leaks or gaps, everything is tight. I even checked all the hoses and connects, they are all tightly connected, so this is why I'm so concerned about this.

 

Last night I had to drive through a puddle and when it splashed some water underneath the car the sound came back. I didn't think of this before, but the first time it happened I also ran through a puddle. Any ideas what this could be?

 

Belts slipping???

 

Are you having any electrical problems too? Like wipers turning on by themselves and so on? Mabye you could try to simulate the puddles with a garden hose then pinpoint the sound?

 

Checked the belts and everything is tight.

 

I did have issues with wipers staying on when I turn it on only once. Found the problem, left side blinker has a leak and when the dealer washed my car I found the wire from the blinker to the inside fuse box wet and the connections were wet. I would run a hose under the car to source the problem or atleast look at it more jacked up, but it's #$^%@* 0 degrees outside I got an appointment to replace my front impact sensor and asked them to check out the blinker leak and will tell them about puddle stuff.
