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.

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.

Dec. 14, 2018 while driving 50 M.P.H. my 2014 Hyundai Tucson engine: 2.0-L I4-di with 113,000 miles, made an awful sound then moments later, the car engine lost all power, lights and steering. I nearly crashed my car. I was fortunate not to hit the car in front of me who immediately after my engine failed, suddenly stopped to make a left turn barely missing this car, I then had to correct my skid then make an abrupt 90 right hand turn off the highway and up a steep driveway, praying it was enough of an incline to slow my car bringing my car to a safe stop. Unable to restart the engine, the key having failed to illuminate the engine lights again, I was forced to call and pay for the car towed back to the Laconia, N.H. Hyundai dealer where I purchased the car and within 2,900 miles before the catastrophic engine failure. After five days I called the dealership only to find out then that the Hyundai Tucson's engine was blown and needed to be replaced. I was told there were no new Hyundai engines available, due to thousands of reported engine failures of the Hyundai 2.0 engine and, I would need to purchase a junkyard engine with and pay for another warranty. I can only hope the seriousness of the 2014 Hyundai Tucson catastrophic engine failure hazard convinces the N.H.T.S.A. to force Hyundai USA, 2.0 L I 4 direct injection engine to recall all Tucson models with these motors, joining other 2.0 engines installed in the recalled Santa Fe's and Santa Fe models with the exact same motor in my car.

Driving 60 MPH down the highway, the vehicle lost power completely and the engine light came on. It had to be towed from the shoulder and the mechanic said the engine was cracked despite it's low mileage and no warning prior to the breakdown, it also wasn't due for an oil change for a few weeks yet. The day it broke down was pouring rain so I was unable to see any possible oil or other liquid leaking out due to the weather.

Barely missing this car, I then had to correct my skid then make an abrupt 90 right hand turn off the highway and up a steep driveway, praying it was enough of a include to slow my car bringing my car to a safe stop. My passenger was shaken. Unable to restart the engine, the key having failed to even illuminate the engine lights again, I was forced to call and pay for the car towed back to the my hyundai dealership in laconia, n.h. Where I had purchased the car about 2 1/2 years, and within 29,00 miles before the catastrophic engine failure. After five days I called the dealership only to find out then that the hyundai tucson's engine was blown and needed to be replaced. I was told there were no new hyundai engines available, (I suspect the scarcity is likely due to the thousands of reported engine failures of the hyundai 2.0 engine) and, I would need to purchase a junk yard engine with a warranty. I can only hope the seriousness of the 2014 hyundai tucson catastrophic engine failure hazard convinces the nhtsb to persuade hyundai USA, 2.0l i4 di engine, montgomery, alabama to recall all tucson models with engine, joining other 2.0 engines installed in the recalled sonata and santa fe models with the exact same engine in my car. Hyundai place safety above all for this otherwise avoidable safety hazard in their manufacture process and design of what otherwise could be a safe, reliable car. Hyundai tucson recall. 2014 hyundai engine failure. Hyundai USA engine died.

My 2014 tucson recently suffered a catastrophic engine failure. I was driving home from work last tuesday (9/18) on a highway when I heard a bang and then the constant rattling from my engine. I was fortunate that I didn't seem to lose power at cruising speeds, but it was still obvious that something was very wrong. I limped it the 20 or so miles to my local service center where it's now sitting. First thing they did was check the dip stick and it was dry. I have my oil changed regularly, I've never had blue smoke out the back, no oil spots, no sign of even the slightest oil leak. So for the dip stick to be dry was alarming. I spent the next day calling around to hyundai dealerships to see what options I'd have. I commute about 70 miles for work, my tucson is at 130k miles so it's well beyond the 100k warranty. Having the engine replaced was basically my only option.
