I have a 2007 g6 2.4L 4cyl when I turn my car on It sounds fine on the outside but as soon as I get inside and close my door the engine sounds like a diesel engine I asked my gm mechanic where get all my service done and they said it should be normal but I don't know because Im never in my car without my stereo on lol what about you guys? Any sounds? Even after I'm done driving it still sounds like it I'm kinda worked I only have 52k on it and still have a bumper to bumper warranty but it cost me $50 to get something fixed so I don't want to bring it in for nothing :( please help!!!!

I have a 3.5 v6 and brought it into the dealer for the same reason, they told me that it was just the fuel injectors making the noise and that it was normal...I've heard this same noise coming from both diesels and new cars that have direct injection systems, but this is the first car i've had that has made this noise from a normal fuel injection system, I don't hear it all the time, just occassionally...I guess its just GM's design..
