On 10/13/25, I was driving on a state hwy & lost all power. All of my warning lights came on. I managed to pull into a driveway & when I tried to start it, puffs of smoke were coming from under the hood. I got it to my mechanic & he said my starter was burnt up. He replaced the starter & discovered that my engine is seized up. It was a scary incident especially driving on a busy state highway. It put my life & others lives in danger. There were no warning lights on prior to this. I acquired the vehicle in February from a car lot. I have had it serviced regularly.

While driving at approximately 70MPH on the highway, my 2014 Hyundai Tucson Limited suddenly locked up with no warning lights, no noise and no prior symptoms. The engine completely seized, causing immediate loss of power. I was barely able to coast off the highway exit to a final stop on the feeder shoulder, in a desolate area. The vehicle has always been properly maintained and is in excellent condition. Upon research, I learned that Hyundai has known of internal engine defects caused by metallic debris left from manufacturing since 2010, which can cause bearing failure and engine seizure. My Tucson's failure matches the same pattern described in Hyundai's Theta II engine recall and warranty extension campaigns. This sudden failure created an extremely dangerous situation at highway speed and possibility of injury while being stranded on an open road. Many owners, myself included, were never properly notified of the risks. I am filing this report because this incident represents a serious safety defect and potential recurrence among similar vehicles that may not yet be covered by recall. I respectfully request that the National Highway Traffic Safety Administration investigate this issue and ensure Hyundai expands its recall and warranty coverage to include affected 2014 Hyundai Tucson Limited vehicles exhibiting this defect that was well-known to the Hyundai Corporation. Date of Incident: October 23,2025 in Houston Texas. Vehicle towed to Hyundai dealer which diagnosed Engine Seized and currently awaiting Warranty Extension Approval (TXXC/TXXI)

The engine experienced catastrophic failure. A piston punctured the engine block, likely due to failure of the connecting rods, an issue known to be associated with the recalled Theta II engine. The engine is still in the vehicle and available for inspection upon request. We were scared and felt seriously endangered during the incident. The engine failed suddenly while we were driving on a busy highway. After a loud clunk, the vehicle immediately lost acceleration and would not respond to throttle input. We had to quickly pull over onto the shoulder while traffic sped past us at high speeds. The sudden loss of power in fast-moving traffic put us at serious risk of being rear-ended or causing an accident. It was a frightening experience that could have resulted in injury or worse. An independent mechanic inspected the vehicle and confirmed there is a hole in the engine block caused by a piston. We brought the vehicle to a Hyundai dealership for further inspection. Still, their communication has been poor, and they have not yet confirmed whether they acknowledge the issue or its relation to the Theta II engine recall. Our independent mechanic has inspected the vehicle and is currently with a Hyundai dealership for inspection. It has not been checked by police or insurance representatives. No third-party inspector has been involved beyond the dealer and mechanic. There were no warning lights, error messages, noises, or performance symptoms before the failure. The engine failure was sudden and occurred without any prior indication of a problem.

I purchased a 2014 Hyundai Tucson with the 2.4L Theta II engine, which has since experienced complete engine failure due to bearing wear. The Hyundai dealership diagnosed this as the same defect covered under Recall 20V-520 and the Kinnick & Coats v. Hyundai class-action settlement (Case No. 8:17-cv-00838-JLS-JDE). Under the terms of that class action, this defect — specifically premature bearing wear leading to engine seizure — should be covered. However, Hyundai Corporate denied my repair, stating that my vehicle did not qualify under the 953 recall. I was never notified of this recall, as I had recently purchased the vehicle used and was unaware of the outstanding recall eligibility or class-action timelines. I maintain my vehicles meticulously, including regular oil changes every 3,000 miles, and this failure occurred under normal driving conditions. Given that the dealership confirmed the defect is exactly what’s outlined in the recall and lawsuit, and the fact that the recall should have applied to my engine based on symptoms and model, I am requesting an expansion of recall coverage or support through warranty or settlement coverage. I have already contacted Hyundai and was denied support. I am requesting investigation into why my VIN is not included and believe the recall scope should be extended.

As with many Hyundai vehicles, soon after I hit 100,000 miles, there was unbeknownst to me and oil leak that caused the engine to seize. There was no indicatior lights warning of the issue. My car’s has been maintained, and although this is under warranty, Hyundai is refusing to fix the issue because I cannot produce oil receipts for the past 4 1/2 years that I’ve owned the car. Those that I have produced, they say are not enough. The service station that I normally had my oil changed at has shuttered. So I cannot get as many oil change receipts as they want. Besides, who keeps receipts of this nature and what if oil changes were done privately?

A recall caused my engine to fail, and needs replacing. it is i believe “campaign 966” They are claiming that i needed to have the system software updated PRIOR to the engine failing. they know that their recall is responsible for the engine failing, but they are trying to go around it by saying that it needed to be fixed before the engine gave out. They NEVER, not one time, reached out about this needing to be fixed. not by email, or regular mail. Nothing. i’m reading everywhere that they do this shady stuff constantly to people, and it is just not right. Thank you

On August 17th 2024 my 2014 Hyundai Tucson wouldn't start. I had my vehicle towed to the dealership so that they can figure out why my vehicle wasn't working. I just leased the vehicle in March 2024. The dealership told me there was an engine recall on my vehicle and they didn't handle engine work and it needed to be towed to an Hyundai dealership. I contacted the Hyundai dealership and they told me there was an engine recall on my vehicle and that it would be serviced on October 17th 2024 at 11 am and hopefully done by 6 pm that day. I was and still am blown away that I have to be without my vehicle for 2 months. Fast forward to October 17th 2024 I'm excited about finally getting my vehicle back as this recall has caused me so much stress and a Major Inconvenience on my life. I contact Hyundai and am told the appointment is for a vehicle diagnostic and they don't have the engine it has to be ordered and then make an appointment to install. I also was told there were 2 other recalls on the vehicle that would be covered under the warranty or recall but the engine would not be covered under the warranty or recall because my name is listed under the dealership name on the title so my vehicle is currently still sitting at Hyundai with no answers from either party about me getting my vehicle fixed and back on the road

For a year my vehicle has this sort of loud noise, sort of a vibration , it has been consuming and burning large amounts of oil, to now where I'm having to put 1-2 Quarts of oil in a week. I was made aware from a mechanic at Hyundai there is a class action lawsuit for an engine defect where the rod bearing breaks which damages the engine and can cause either the engine to seize or catch on fire.. Hyundai refused to fix the engine until it is deemed a total loss despite them being aware my vehicle is already displaying the symptoms of this engine defect. This is so unsafe for not only myself and my family but other motorists .

Hyundai Corporate and Bentley Huntsville are refusing to fix faulty engine in vehicle. Bentley Hyundai submitted a fake PA asking for Hyundai Corporation to pay for engine combustion cleaning. Hyundai Corporation and Bentley Hyundai Huntsville Alabama are not honoring extended warranties on known engine failure in their vehicles that are stalling on highways, catching fire and damaging other car parts such as catalytic converter, compressors and rod throwing of engines on highways. This is a danger to consumers and should be addressed.

Friday [XXX] I was driving my 4 year old to preschool. We were on the highway traveling about 55 mph. Without warning my car engine turned off. After coasting for awhile, because I couldn't pull over due to guardrails, I was able to get to shoulder of road. Vehicle was towed to local chevy dealership with inspection result of seized engine. car is available for inspection at chevy dealer, manufacturer has not inspected yet because I will need to have it towed the 35 miles to their dealership but they are aware of the situation. I didn't notice any symptoms prior to engine failure. This was a very scary situation for me and my child. I was so worried I was going to get hit by a car traveling behind me since my car was slowly coasting in the lane of the traffic and I couldn't get off of the highway right away because of guardrails. Once I could get off the highway, my car could only coast enough to get about 1 foot off of road which caused a hazard to other vehicles, myself, and child.
