Replying to: grosloup (Jul 12, 2008 7:15 pm) I've read other blogs stating that the BCM (Body Control Module) and PCM (Powertrain Control Module) should be replaced and reprogrammed to eliminate this problem. If you ever get a solution on the fried radio/cd player problem please let me know! I really think that all Chevy's are Lemons! |

Replying to: klnnc (Feb 19, 2008 10:12 am) Can anyone help me out? I have experienced the same 'popping' sound as others have reported. I have an 2009 Equinox LS with 5000km on it and have also been experiencing the same 'popping' sound at the same speed (18km/hr in my case). I brought it to the dealer - they could not locate the issue. I only hear the sound after a cold start up and accelerate past 18km/hr (does not make the sound at any other speed). If I come to a stop and then accelerate past 18km/hr, I do not hear the sound - it only occurs after a cold startup. The vehicle runs fine, but it sounds like a spring popping... Any ideas? Thanks!

Replying to: northerner19 (Nov 16, 2009 1:28 pm) The noise that you're hearing (thump thump thump) or (pop pop pop) is caused by the EVAP "Vent Selonoid" doing it's emissions diagnosis and it's totally normal. It has nothing to do with the speed your going, you will eventually hear it at a stop (always on cold start) The noise comes from underneath the back of the vehicle on cold starts or a couple of seconds after. Mine does the same, sometimes I can hear it and sometimes I don't. That's why some people think that not all Nox's do this particular noise but they all do it occasionally. Trust me it's been 4 ½ yrs that I drive my Nox, up to 82,000 miles and I can still hear this weird "thump thump" sound at least once a day and never had problems with that. Like I said the system is only doing it's job. Got to live with it.

Replying to: laserblue (Nov 17, 2009 5:02 am) I should clarify, it's not a 'pop pop pop' sound, it's more of a "boing" sound.. like a spring sound. It's just happens once (not a consecutive sound). |

Replying to: klnnc (Nov 16, 2009 4:07 pm) Thanks. I was hoping you would post a reply. I have not found anything further regarding the issue. I am planning to take a trip to a different GM dealership next month and have them take a look at it. If anything comes up, I will post a comment. Thanks

Replying to: klnnc (Nov 17, 2009 4:00 pm) Received a telephone call from G.M. in 2006 explaining all about that noise and the system. So I think I know what I'm talking about here. Or maybe G.M. is off the track to KLNNC ? They must know what there talking about, they built the truck at that place. |
