I just got this car last week. Today I noticed an electrical hum somewhere in the left rear when the car is off after its driven. I looked underneath and it appears to be coming from a black box that looks like its connected to hoses (emissions?).
Anyone got any ideas?

 

That's the EVAP system doing a self-test by pressurizing the fuel system. Totally, normal.

Also, you don't have a GLX, there's no such thing.


If you're confused about your trim level, it's explained in great detail in the FAQs.

 

Thanks!

BTW it is in fact a GXE. Thanks for the correction.

 

Its ok...i have a GX-L

 

No you dont.

 

i was joking.

 

No you weren't.
