NHTSA Complaint #11443845 — 2013 HYUNDAI TUCSON

My engine failed without any check engine lights prior. Started making a REALLY loud flapping noise when accelerating and would get worse the higher the RPM and the higher MPH. Even while coasting the noise was still prominent. It started around 12pm on 12/11/2021 and at 1:07pm (approximately 1 hour later) on the same day, it officially failed. The noise had started and gradually got worse while I was on the highway going approximately 65-70mph. I had stopped and pulled over shortly after it had started and made some calls to some certified Hyundai dealers to try and see what to do. I had made an appointment for first thing on Tuesday morning, 12/14/2021. I told them I would drop it off as soon as possible because I was sure it was going to blow. Tuesday appointment was the earliest appointment available at ANY Hyundai dealer within an acceptable/safe range. After I had made the calls, I proceeded to try and make it home. I was about 35-40 miles to home and my engine got EXTREMELY loud and not running properly. I was approximately 10 minutes from the dealership I bought my car from and I decided, if I made it there that I would leave the car there and not drive it home because I did not feel safe. About 45-60 seconds after the noise got so loud I couldn’t hear the radio. I was trying to find a safe spot to pull over but apparently didn’t make the decision in time because at 65-70mph (cruise control set at 67mph) my engine made a crash/boom sound then every light on my car’s dash lit up and car longer was functioning. I got pulled off to the curb immediately and shut the car off. Approx 5/2021, check engine came on, code read all cylinders were misfiring, spark pugs were changed because no engine failure was detected. My KDS recall serviced 11/27/2021, approximately 78,000-79,000 miles. Shop never mentioned and concerns with my car while it was there. Engine failed just over 80,000 miles.
