Okay, so the past two days I have had the P0455 code come on. Cleared it both days and it came back. Checked gas cap it was tight. 2011 with 35k miles on it.

My G6 does the same thing and the cause cannot be found. Told the dealer I would only pay their $95 eval fee IF they find and fix the cause. I didn't wind up paying.

I hope this car is not as difficult.

Anyone with experience with this?

Thanks!

 

Generally, if it isn't the gas cap, it likely is an evap line might be leaking and causing the code.
