On [XXX] my 2011 Hyundai Sonata seized and all lights illuminated on the dash while accelerating on to a busy street. I was able to pull to the side of the road but unable to restart the vehicle. I had it towed to Wesley Chapel Hyundai (27000 Wesley Chapel Blvd., Wesley Chapel, FL 33544) who notified me that there was an oil pan leak which was the possible cause of the engine failing. They corrected that issue and completed an oil change on 3/14/2025. I picked up the vehicle and there were no issues on the drive home which was approximately 11 miles. Then on [XXX] after driving approximately 24 miles to my place of employment, the engine started knocking but I was able to arrive and park with no issues. I immediately turned the vehicle off and contacted the closest dealership to have it towed there which was Courtesy Hyundai (3810 W Hillsborough Ave, Tampa, FL 33614). I informed them that the vehicle was on it's way there and to notify me when it arrived. It wasn't until I called several hours later that they advised me the vehicle was received and that they would be submitting a claim to Hyundai Motors of America for the Engine. I had to continuously call to get updates as no one would contact me. I then was told that HMA was requesting service records. I emailed those records to the service advisor on 3/20/2025. I had not heard anything for about a week so I contacted the Service Manager who stated HMA is requesting additional service records. I asked why I was not informed sooner but was unable to get a real answer. I then forwarded those documents directly to the manager on 3/28/25. I was then notified on 4/1/25 that HMA had denied the claim due to negligence of the motor despite providing the requested documents as well as confirming via Hyundai's website that my vehicle was affected by the Sonata Engine Connecting Rod Bearing Inspection Recall Campaign. I am now being quoted $4059.89 + tax to replace the engine. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

On June 28th 2023, while driving on Route80-West near Parsippany, NJ my 2011 Hyundai Sonata GLS seized on the highway. I was forced to veer to the shoulder as the oil light flashed on, followed by multiple lights flashing on with immediate engine failure. I waited almost 3 hours for a tow to arrive late night, where many vehicles continued to speed past dangeriously close to my seized car. Even with my hazard lights on, this is not a safe situation a driver should be in. Having an engine stall is especially dangerous when traveling highway speeds. I assumed my engine stalled due to the widely known recall issue that Hyundai Theta-2 are susceptible to. After having my Sonata towed to Towne Hyundai at Denville, NJ- they informed me that it was not a valid engine recall but that my oil completely drained, destroying my engine in the process. They said quote "the oil pan cap was not properly torqued, resulting in it falling off mid-drive. Your last mechanic probably did not tighten it, and after months of vehicle vibrations, it fell off". After speaking to my regular mechanic and gathering opinions of many others, nobody has seen an oil drain plug fall off on its own. My last oil change had been almost 2 months prior to the incident, only 1,400 miles driven since then. I also had my same mechanic fix a check engine light issue 2 weeks before the incident, where they again saw no oil leakage or notifiable issues. I did not hit any potholes or damage the underside, my dash cam footage can confirm this. Towne Hyundai quoted me nearly $13,000 for a new rebuilt engine, and refused to front any cost. They denied it to be apart of their engine recall program. They returned back saying they can install a junkyard find engine and fix the car for around $6,400 that I have to pay out of pocket. After escalating my issue with Hyundai Corporate and building a case, they said they would speak to Towne Hyundai-Denville to confirm the incident.

Well, very simply I was merging onto a parkway and pushing down on the accelerator, car was speeding up then I noticed that it seemed like I wasn't getting any acceleration. Looked at the dashboard and saw that it seemed all the lights were on and realized that the engine had shut itself down. Pulled off to the shoulder and tried to restart it (head kind of a whirring noise), but it wouldn't start.

My car caught fire and was not involved in an accident. I was going around 30mph, all the dashboard lights came on, the car would not accelerate, so I stopped the car and turned on the hazards. The car started smoking soon after so I left the car. A few moments later it caught fire. I called 911 and had the fire put out. I have never received any notices from hyundai about my car. I purchased the car late april of 2017 used. I have read this issue is not uncommon with this car.
