NHTSA Complaint #11695711 — 2019 HYUNDAI KONA

My Kona has been stalling/hesitating when accelerating. It has been happening for a little over a year. It got very bad and the check engine light came on. I had it towed to Hyundai dealership and they said it was the fuel injectors so I paid to have those replaced, they said my warranty didn’t cover it. Replacing the fuel injectors made the car drivable but it was still stalling/hesitating but Hyundai said it was working properly. So I took it home. I have been driving it and it just keeps stalling and hesitating more and more. It is stalling and hesitating and has lack of power when I try to accelerate. I am afraid one day I’ll stall in traffic and get hit or cause an accident. I have also just realized my Kona has been using excessive oil. I just had an oil change mid August and today had to add at least 3 quarts. Even when I had my oil changed, the shop said I barely had maybe a quart in there, when it was just changed in May. We do not see any oil leaking out from anywhere. I have no choice but to use it to get around and Hyundai said it was working properly. I have recently looked online and I seen a lot of other owners reported the same issues. I have contacted Hyundai but they say theres nothing they can do. I am not sure where to go from here.
