NHTSA Complaint #11670368 — 2013 HYUNDAI SONATA

I purchased a 2013 Hyundai Sonata in 2022. I never had any problems or warning signs of vehicle until late Feb 2025. The engine begin to making a knocking sound and stalling almost causing my son to have an accident. After researching the issue I found that there had been a law suit filed against this company for the engines in those vehicles and that they had placed a limited lifetime warranty on the engine in my vehicle. I reached out to Hyundai and they assured me that my vehicle was covered under the TXXI warranty due to the class action suit filed against them. Next they set up an appointment for me to take the vehicle to the local Hyundai dealership which was Bentley Hyundai in Huntsville, Alabama. I had the vehicle towed there in March 2025 and was immediately met with unprofessional dialogue on my arrival. I explained that an agent from Hyundai corporate had set and appointment for that day but was told that they had no knowledge of it. They received the car and stated that diagnostics had to run on it and that they had to send the paperwork back to corporate for approval to replace/repair the engine. About a week later after unsuccessful attempts to contact the dealership, I was informed that my claim was denied due to maintenance neglect. Once I asked for further clarification the associate told me that it “looked like the oil had never been changed in the vehicle”. I assured him that it had been maintained properly since the date I purchased it. They pulled the carfax and was able to verify all of my maintenance records and that the vehicle never went over 5000 miles before oil changes. I then asked to speak to a supervisor as the rep began to be very disrespectful in his tone and language (which was always by text and not phone). The service manager that I spoke to after this helped escalate the situation to the appeals department. This was a known issue for these motors and the fact that they would put my family’s lives in jeopardy is upsurd.
