GinaB79 0 Posted June 5, 2017 Share Posted June 5, 2017 I own a 2013 Chevy Spark. I am right around 46,000 miles. Starting today I have been hearing what sounds like a very faint humming sound. It started just as a sound when letting off of the gas pedal. Now, it will do it anytime but not as loud. I can hear it inside the car as well as middle of the car when in park. But like I said, it's very faint. Any thoughts? Link to post Share on other sites
Retired old Gearhead 201 Posted June 5, 2017 Share Posted June 5, 2017 (edited) If sound is evident when in park..it is NOT wheel bearings..if the cars runs a smooth idle and drives OK..worry not and just drive it. Could be the air/heat fans making the noise..so try to turn the fans off and see if it disappears .. could also be the fuel pump making the noise..fill up the tank to see if that resolves it.
