Re: 2014GC Strange sound from the engine room when dead stop
If you park and turn it off, do you hear the same noise without the engine running? I ask because it could be the load leveling suspension. There is a compressor that will run intermittently. I won't say all the time, but often enough. You could try to force it on by having a friend stand on the hitch or sit in the cargo area to simulate a load and change the height.
