NHTSA Complaint #11460987 — 2017 HYUNDAI SONATA

I have a 2.4L 4 cylinder enginr.lI noticed that I would get my oil change and a few weeks later my oil light would come on and I would have to add oil. This had been going on for the past year with no one able to provide an explanation. About a month or so ago, my car began to violently shake,, loss acceleration and my check engine light came on. A mechanic looked at my vehicle advised he saw oil on all my spark plugs and said the 3rd chamber was losing compression. Doing some research I found out that the engine in my car has a recall for defective connecting rod bearing issues. The dealership is telling me that is not the issue even though the have not broken down the engine as the issue could be due to the recall....I need help I am without a car and my warranty has expired.
