Hyundai
Tucson

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 contact owns a 2014 Hyundai Tucson. The contact stated that while driving at an undisclosed speed, the vehicle inadvertently lost motive power. The contact was able to coast to the shoulder of the roadway, where the vehicle was able to be restarted. The vehicle returned to normal functionality, but the failure became a regular occurrence. The low oil warning light was illuminated. The vehicle was taken to the dealer, and an oil consumption test was performed. The contact stated that after performing the oil consumption test, the contact was informed that the vehicle was consuming over 1 quart of oil per 1,000 miles driven. The contact was advised by the dealer to continue driving the vehicle for another 1,000 for further evaluation. The manufacturer was notified of the failure, and a case was filed. The failure mileage was 110,000.

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.

The high pressure fuel line began leaking gasoline after warrantee replacement of engine.

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.

While I was driving ,my vehicle unexpectedly shut off without warning ,creating a dangerous situation ,thankfully I was able to safely pull over .Due to this issue I had my car towed to dealership for inspection I discovered my car is included a recall number 22v056000 Hyundai refusal to honor a recall that directly affected my car Hyundai have denied the recall on my car for no reason

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?
