2020 6.6 Has Custom Still not quite 30,000 miles. My 3 year bumper to bumper warranty expired April 30. Just a few days before, my orange CE light comes on. Only thing noticeable was that it would not allow remote start. It didn't seem to go into any other default settings. So I went on line to schedule my service. They can't get me in for a couple of weeks. Finally get serviced a few days after having changed the air filter and an oil change an the u tell me my purge canister is bad. Will be almost $300. So I ask about the warrant, having scheduled the service prior to the expiration. They say it's a no go, as GM will only go off the date the computer is connected to the truck. This northern Michigan dealer is below par anyway, may get a hold of another dealer a couple hours away this time. So I get the truck back and the light is out. They cleared the code, without having saying anything and all was back to normal. Now a week and a half later, the truck won't start via remote this morning and the light is back on. I haven't looked to see how difficult it is to get to the cannister yet. Wondering if anybody else is seeing a CEL much? Looks like I'll probably start looking into a catch can. I love this truck, but if this is gonna be a thing, I'll start reviewing my options.
Any GM customer service listening? 6.6 gas, 29650 +/- miles.
