What's wrong?
The high-pressure fuel pipe on 2021-2022 Hyundai Sonata and Santa Fe vehicles with the 2.5L turbocharged engine links the high-pressure fuel pump to the fuel rail. The pump raises fuel pressure, and the rail feeds fuel to the engine injectors. That connection has to seal tightly while the engine is running and fuel pressure is high.
On affected vehicles, the pipe connection was not tightened correctly because the supplier tool was used at an angle and the tooling pin was unstable. That left the pipe with less torque than required and improper alignment at the connection. When the connection does not sit and clamp the way it should, fuel can leak between the pump and the fuel rail.
What you notice is tied to that leak. Hyundai lists fuel odor, smoke, a burning or melting odor, or the MIL, which is the malfunction indicator lamp on the dash.
