My car started making a noise back in Dec/2024. I scheduled an appointment with Quirk Hyundai in Braintree, Ma on Dec 11, 2024, and paid for a diagnostic the service center came back that it was the oil pan leaking so on this date I had that repaired that same day total cost was $254.76. Please note that my car was under warranty at this time. On [XXX], I brought my car back to Quirk Hyundai in Braintree because the noise had returned and was intermittent, and passenger side makes loud noise when riding over bumps and the car was shaking when driving pass 65 MPH. When I had the diagnostic done on 03/29/2025 the service center came back and said it was the mismatch tires that were put on my car by an outside provider (townfair tire) and that I needed 4 new tires, oil changes, mount and balance tires and four wheel alignment which cost me $959.08. Three days later while driving home from work the noise returned and my car ept shutting off one me. I went to AXP North in Randolph MA on 04/08/2025 (had to make an appt) for a second opinion diagnostic and they told me that my car will need a new engine as the one now is failing. I called Quirk Hyundai back on 04/08/2025 and told them this and they asked to bring the car back so they can recheck my car for misdiagnosis. So, on 4/09/2025 I called Quirk Hyundai for an update the failed engine was confirmed, and now because my car is 40 miles over the warranty it cannot be fixed by Hyundai. This car is a 2018 and should last me longer than 2025. My car is only 8 years old and I have cared for the car whenever it needed maintenance. I need someone to please call me to discuss further at [XXX] . I need a new engine and Quirk Hyundai will not cover the cost despite my several attempts to have this noise resolved when care was under warranty.
