so like a week ago my engine lite came on. I pulled the code P0448 EVAP solenoid short. took it in to the STEALER to have it looked at thinking that it would be covered under warranty .. not he case. they said that the have to change the filler hose complete assembly $340... doesn't make sense. anyone else have this issue? I have 78000 KM ( Canada) as much as I love this van I hope this is not the start of the problems.. I have had GMC savana for the last 12 years and I switched because of the on going problems... any help?
