Experiencing a low frequency popping, rumbling sound at all speeds at partial throttle. Sounds like an exhaust system leak. Worst when it rains. (cools the exhaust?). Has anyone had similar experience? or any ideas?

 

welcome to HAF.......
.. my advice ....... do not waste any time trying to figure it out,, your car is totaly under warranty, take it to dealer and have them deal with it.........
Any work that you might do, could void the warranty

 

thank you for advice. After long drive to dealer, noise is muted and difficult to hear. It comes and goes,but it is alwaysthere.
