   I have replaced the GDI engine on the 2017 Hyundai Accent once. I have also had the catalytic converter replaced 3x. The car lunges as if there will be another catalytic converter issue soon. Hyuandi recommended a fuel induction completion to prevent the issue from occurring again, but it did. This is a safety issue because the car and stall out at any given time. The cause of this issue has yet to be detected. It is believe a recall is needed on the GDI engine and catalytic…

   I have had this vehicle for 5 years and even replaced the engine in this vehicle for it to end up with the same issue. I take very good care of it and get its maintenance done. But the car is slow to get up to speed and misfires really bad. I replaced the spark plugs in it and they were coated in oil. The airbag sensor will come on indicating it’s not operating properly. Overall a very unreliable vehicle that has multiple issues. It has ended in catastrophic engine failure…

   To preference, I have only owned this vehicle for less than six months, and that the only major issue concerning the vehicle was the replacement of the catalytic converter manifold.

   I had two different mechanics I trust tell me that this car has a particular engine that had an error in manufacturing, but Hyundai didn't correct it, because it would cost them too much. The error is heavy oil burning, such that it destroys the catalytic converter. I am now on my third catalytic converter in this car, and the check-engine light is beginning to flicker. Mechanic recommended contacting Hyundai corporate to file a complaint. He knows of others with this same…
