Checking my garage before going to bed last night and hear motorized humming coming from rear of the GX. I slide underneath and it seems to be coming from the spare tire area. I started the engine, then shut it off and the noise went away. The noise reminded me of the air suspension pump on my old Denali, but my Gx has the standard suspension. Any ideas?

 

lol, it freaks out many owners here.

Good to know! I did scan the manual but missed that section.

 

Fixed your answer! Thanks Tecm

 

I have to think this has been in a thread over the years.

 

 

After 2.8 years finally heard this.... quiet day at cabin and came back from a walk and hear that slight hum/whine from the GX. Right around 5 hours since I came back from a drive on the lake beach.

 

It sounds like a pump running, like a fuel pump but could be suspension air bag pump too. Any thoughts?

The rear compressor in our 2011 GX occasionally runs randomly. Wondering if anyone else has noticed this?

I dont know how often this happens, but I have heard it running at random twice in the last 6 months just sitting in the garage. It's pretty quiet, so without it sitting in a quiet garage it's probably not noticeable at other times.
I haven't noticed any rear suspension changes or ride differences. The height control all works fine and it self levels as it should with weight changes in the rear, or loading weight on a trailer.
The first time, I thought it was just random, but hearing it run again tonight made me wonder. It runs for a minute or two, then shuts off.
I have not crawled around under the rear and done a throuough inspection yet, but I did do the diff fluid a couple weeks ago on it and did a brief inspection and didn't note anything odd.
Wondering if anyone noticed similar random compressing on their GX?

I went into my garage tonight where I have a TV on 24/7 with speakers in the ceiling.... What is that sound? It doesn't match what the TV is showing...HAHA, I rarely hear this but it hit me

 

Hi all
I just discovered today that my AHS seemed like it was still on after I had turned off the car. There was this low motor noise that I heard coming from my right wheel well about 4 hours after I had stopped the car. Only reason I heard it was because it’s a quiet cold winter day. I got in the pushed the off button for the Suspension height And then checked and it was gone.
Has anyone any ideas what this could be or encountered this before? is this normal and I need to make sure it is off or Do I need to take it in to the dealer ?
Much obliged for any insight into this.
2019 luxury here. Been two weeks since I bought this car
