The other day I noticed a some yellow snow under my HHR at the rear driver side. I wasnt sure where it came from. Today my engine light turns on and i get the code P0449. I looked it up and see it points to the EVAP. I've seen a few post about this might be wiring harness, gas cap, etc, but since I seen the yellow snow in the back, I was thinking this might of been gas. Any ideas what this can be?

 

@simonb, I’m sorry to read about your concerns with your HHR. I can understand how frustrating trying to figure this out on your own can be. I’m sure there will members to help you shortly.

I would like to take a look into any recalls for your vehicle. Please, send me a private message with the VIN. Thank you in advance.
