The recall states that this issue occurs over time. It also impacts every 2008 and 2009 fortwo sold.After 10 years, if it hasn’t burst into flames. Your probably fine.
If anything, being ten years old is a bad thing as it seems the fire rate increases as the vehicles age.
It looks like MB hasn't figured things out on their end. That's why you haven't received any recall notification and why you can't even take it to the dealer to get it fixed yet.
