2019 Kia Sedona Fuel System Problems

Your car is emitting a strong fuel odor that has made you and passengers feel sick, and your check engine light has been flashing on and off. The dealer has replaced several fuel system parts multiple times over the past year but hasn't been able to fix the problem. An independent mechanic confirmed the leak and noted that the exhaust is running very hot, which could potentially cause a fire hazard. Fixing this will likely require a thorough inspection and replacement of fuel system components, possibly including the fuel injectors, fuel pump, or fuel lines.

You're noticing a strong fuel smell inside your cabin, and your check engine light is staying on. Your dealer found that the high-pressure fuel regulator was faulty and replaced it, but the smell and warning light came back. The fix will likely involve diagnosing why the replacement regulator is also failing, which may require checking fuel system connections, seals, or getting another replacement part.
