  Hyundai Motor America (Hyundai) is recalling certain 2011-2014 Sonata and 2013-2014 Santa Fe Sport vehicles previously repaired under recall numbers 15V-568 and 17V-226. The high pressure fuel pipe that connects to the fuel pump outlet may have been damaged, misaligned, or improperly torqued during the engine replacement procedure, allowing fuel to leak from the pipe.

  Risk: A fuel leak in the presence of an ignition source can increase the risk of a fire.

  Remedy: Hyundai will notify owners, and dealers will inspect and replace the fuel pipe, as necessary, free of charge. The recall began March 1, 2019. Owners may contact Hyundai customer service at 1-855-371-9460. Hyundai's recall number for this recall is 180.

   1. The car began to randomly stall and stop running. This happened while driving and it was extremely dangerous. Typically, the engine would restart after at least waiting 15 minutes. Any attempt to start the car before that time would fail. 2. When the stalls happened, the car acted as if it had run out of gas. The engine would simply stop running WITHOUT WARNING, at intersections, on city streets, and on the freeway at high speed. It did not matter how full the gas tank…

After I took it home the check engine light had come on not too long after, the engine stalls when turning the key, pressing on the brake helps start the engine. Turns out the car was a salvage title and my dad didn’t know that and I didn’t know what that was.

   I tried pumping gas and the car would not let me pump the gas into the car. I had to hold the the gas pump hose and pull the trigger myself to pump the gas, which would still make the clicking stop noise that stops the pumping of the gas. Then when I started driving, the check engine light came on. Went O'Reilly to test the check engine light code and it popped up with a P0449 code for the evaporative emissions (EVAP) vent control valve.
