The 2023 Hyundai Sonata has two recalls, both carrying fire risk: a fuel tank that can melt and leak after contacting hot exhaust components, and an electric oil pump controller that can overheat.
On the fuel system side, a damaged check valve can allow air into the fuel tank, causing it to expand until it contacts hot exhaust components nearby, melting the tank and creating a fuel leak that raises the risk of fire. The second concern involves the controller for the idle stop-start oil pump assembly, where damaged electrical components inside the controller can cause it to overheat, also posing a fire risk.
