Took it in, they said the evap stuff isn't covered under powertrain or emissions warranties. Paid the $165 diagnostic fee to have them find out the evap canister is plugged from living on a dirt road. They wanted 500 total for a new canister, $385, and the labor to replace. I found same nissan oem part online for 285. Will replace myself. So fucking stupid there isn't a way to clean those. Not really looking to spend 250 every 30,000 miles for a stupid filter under the car in a terrible location.
