Default Noise

My 2010 coupe has a noise. it can only be heard inside with the doors closed while the car is in drive. I only hear it when i am stopped.
Dealer is not sure, cant really hear it but thinks its the exhaust.
noise sounds like when you put bad gas back in the day.
I am very picky and drive it everyday. It was not there a month ago
Has anybody had this issue or have any suggestions?
Thanks

If you're looking for help in diagnosing the noise, you might start by describing it. "My car has a noise." What is anyone supposed to do with that?

I thought I did by saying it sounds like when you put bad gas in a car back in the day. It is hard to describe. It sounds with the same rhythm of the engine and it stops when you are in park or in neutral. Sorry i am not too mechanically inclined. Thanks for your interest

juancarlosg,

Have you had a chance to ride along with the dealer to help in pointing out the noise? Keep us posted. Feel free to contact me or Evan via private message if you have any further questions. Thank you.

Tricia, Chevrolet Customer Service (Assisting Evan).

I only hear it when the shifter is in D Drive and stopped. I do not hear while i am moving or when the car is in Park or in Neutral
Does that clarify?

I would say that narrows it down to the transmission, but I'm no expert. Could you just be hearing the fluid circulating through the transmission?
Hopefully someone with more knowledge will chime in.

Maybe it's the normal sound of the brake relay. Happens every time you apply the brakes.

Maybe you just need a new relay... the 4-prong relays are noisier than the 5-prong replacement.

exhaust pipes perhaps. sounds like something is loose if you only hear it in drive. i had the same problem and with the vibration, one of the claps had come loose. had it tightened and haven't heard the noise since.

That would be my first guess as well.

Kinda hard to explain a sound but when I put my truck in gear with the brake on, it sounds like fluid flowing through some valves.
