  • Hint: Use a descriptive title for your new message
    If you're looking for help and want to draw people in who can assist you, use a descriptive subject title when posting your message. In other words, "I need help with my car" could be about anything and can easily be overlooked by people who can help. However, "I need help with my transmission" will draw interest from people who can help with a transmission specific issue. Be as descriptive as you can. Please also post in the appropriate forum. The "Lounge" is for introducing yourself. If you need help with your G70, please post in the G70 section - and so on... This message can be closed by clicking the X in the top right corner.

I seem to get this diagnostic code shortly after I get gas. Anyone else get this?
I check a solid check engine light for while (like a week) and then it disappears. See below for history:

Same issue here. I'm leasing a 2025 as well. It has happened 5 times this year, including 3 times this month. It's scheduled to be serviced for the 3rd time. First time, they ran a smoke test and found no issues. The second time, they replaced the evap cannister. None of this fixed the problem. Car is running fine otherwise. It is just annoying not to mention inconvenient for a brand new $50000 vehicle.
 
Has anybody checked to see what the fuel tank pressure sensor is reading when this is happening? If it is an impossible value, then it would be the next part to throw at it.
