There are 4 owner-reported fuel system complaints for the 2016 Hyundai Sonatain NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
The fuel pump where the fuel line connects to it is cracked and squirting fuel all over that area. Some time ago I started smelling fuel when getting close to the vehicle or when opening windows. Took it to a shop to have it checked out and the technician couldn’t find the problem, since there is no check engine light on or any type of warning. A few days ago I decided to check the bottom part of the fuel tank and noticed that there were traces of leaking fluid. Reached to it and checked it closely and certainly was fuel dripping. Checked the top of the tank where the fuel pump is and found out that the problem was there. Did some research online and found out that that’s a very common fail. I Would like to have it investigated and recall all those failing cars for my safety, my family’s safety and everyone else that trusted this company and is letting us down. First time I noticed this was back in 2022 and is when I took it to the shop.
