The 2020 Hyundai Sonata has 6 recalls, the most serious being a fuel tank that can expand, contact hot exhaust components, and melt, allowing fuel to leak and creating a fire risk. This fuel system issue appears across two related recalls: one affecting vehicles with a 1.6-liter turbocharged engine, where a worn purge control check valve allows the tank to swell, and a broader filing where a damaged check valve lets air into the tank with the same result. There is also a software defect in the Remote Smart Parking Assist feature, where the vehicle can continue moving in its last commanded direction even after the system detects a malfunction, raising the risk of striking a bystander. On the hardware side, the trunk latch can become damaged and prevent the trunk from opening from the inside, trapping anyone inside the compartment. A label recall also affects vehicles built during a specific production window, where the tire pressure label and owner's manual list an incorrect tire size, which can lead to installing the wrong tires and affect handling.
