“What component or system failed or malfunctioned, and is it available for inspection upon request? Since april 2025 i’ve been having low oil readings in my vehicle despite regular oil changes I took it into the dealer since my vehicle was still under warranty, which they stated only one part was under warranty. I had to pay $800 after this was replaced. I started having engine light come on. This engine light when I paid a diagnostic fee I learned that the cylinder three was misfiring. It was suggested that I have an oil change and get the oil level checked again within a week. …”
