Hi, this is Bo, an auto expert on RepairPal's Car Genius team! Ah, the ol' check engine light—like a surprise party you never wanted. It could be a few things if it’s popping on after long drives. Common culprits include the oxygen sensor, catalytic converter, or even a loose gas cap. Modern cars are finicky with their emissions systems, and any hiccup there can light up your dash. Given it’s been a couple of months, it's worth getting a diagnostic scan. Most auto parts stores will do it for free. That'll give you a code to narrow it down. You might be able to fix something simple, but if it's more complex, at least you'll know what you're dealing with before chatting with a mechanic. If you need more advice, have other questions, or need to find a certified repair shop in your area, just let me know!
