NHTSA Complaint #11635372 — 2019 HYUNDAI KONA

On Christmas, Wednesday 25, 2024, my husband and son were in the car with the husband's driving and they heard a knocking sound as if going from the engine, and the car was losing power; there was no the "check engine sign" but it was remembered that few days before that there was the oil lamp sign lighting up for seconds and then disappearing, and also, the blind spot signal not working. So, we brought the car to our local mechanic, and he inspected the engine and said that the left back cylinder is broken. I called the Hyundai corporation and they advised to bring the car to the Hyundai repair shop- the car was then inspected in the shop - found some " lower rod bearing failure" but the Hyundai denied a Goodwill claim because of some maintenance neglect which has not been true - they had all our oil change receipts - I am the original owner - bought the car in finance and overall paid it off in 5 years - the car cost me 30K brand new- we were changing oil as soon as the message for the need to change oil would come up - every 5 - 5.5 K miles, all the records have been sent to the corporation, they have just said " neglect" out of the blue...They have denied the Goodwill engine replacement based on that falsely stated "neglect." I see there have been recalls for the oil ring piston issues in Konas including 2019 - for the engines 2.0L Nu MPI- the cylinders would start knocking from some overheat of the ring. Our engine is 1.6 GTI - but the engines are related, and our problem seems to be the same as in that 2.0L Nu MPI engine. Please, look for the similar cases for those Kona GTI Turbo engines for 2019- the one we have, seems that our Kona is fitting into the profile of those defected engines and the recalls like the one under the number 21V 301 203. Please, help!
