What's wrong, in plain English
Hyundai says a damaged check valve in some Sonata vehicles can let air get into the fuel tank. That extra air can make the tank expand, and the expanded tank can touch hot parts of the exhaust system. Contact with the hot exhaust can melt the fuel tank, so Hyundai is having dealers check the check valve, fuel tank, and engine control software.
What you should do
2. Contact a Hyundai dealer or call 1-855-371-9460 to schedule the inspection and repair.
3. The check valve, fuel tank (if needed), and software update are all free.
