Wont start

Hi, this is Bo, an auto expert on RepairPal's Car Genius team! So your 2012 Hyundai Sonata has been sitting like a dead phone for a year, and now it’s rattling and smoking when you try to start it? That’s a double feature no one asked for! The rattling could indicate an engine issue—like a timing chain or internal damage—while the smoke might mean something’s burning where it shouldn’t. After sitting for a year, fluids could be gunked up, and seals or gaskets might have gone bad. It’s probably time for a deep inspection before you try to fire it up again—don’t push it, or it could turn into a bigger repair bill.
