2014 Hyundai Elantra: sudden loss of power

Filed Apr 29, 2026 · Engine, Transmission · TX

The 2.0L Nu GDI engine in this vehicle is experiencing terminal internal failure. Following a P1326 KSDS warning event, a borescope inspection at an authorized dealership documented severe cylinder wall scoring in all four cylinders. Despite this documented internal block destruction, the manufacturer has denied the mandated settlement warranty repair based on a software-based proxy test (BCT). The vehicle was returned in an unsafe condition and is currently stalling and vibrating violently while in traffic, posing an immediate risk of loss of power and traffic collision. The manufacturer is ignoring the documented physical failure of a core engine component.

This has occurred three separate times, but this report explains what happened during the most recent occurrence. I was driving at 40 mph. The car in front of me hit their brakes, so I lightly tapped my brakes to slow down. When I tapped the gas pedal, the car would not increase speed. The check engine light, oil light, and battery light each turned on simultaneously. The car then stalled completely, but the lights remained on and the car didn’t lose power. I hit the brakes (which were now hard to push down), hit my emergency flashes so that the car behind me would pass me, pulled over to the side of the road, and then I turned off the car. When I turned the car back on, 30 seconds later, all of the lights were off and the car started with no issue.

I had my vehicle serviced to diagnose a ticking problem I had. I was told that it's an engine issue & known to Hyundai. As I was traveling 177 miles from home, the engine lost power and failed. Thankfully it didn't cause an accident. My engine has less than 100,000 miles!!! This should not happen and every engine that experiences this ought to be replaced through a recall!! Probably, most people don't even realize this is a problem and let themselves be taken advantage of.

2014 elantra driving the car in town at slow speeds, usually around 15-25 miles an hour, with rpms at about 1250. First noticed an issue with extremely jerky driving, but added gas and the problem went away, and I thought it was a one-time thing. About a week later, it happened again. I set an appointment to the murdock hyundai of murray utah to solve this issue that was putting my family and my security in risk. On june 18th around 6 pm, the did a diagnostic check in the dealership and then, they recommended me to clean my gas injectors, to do a tune-up, to do an alignment and to add new four tires change since they were totally damaged., some kind of hyundai solvent cleaners for the gas engine. All of the services had a total of $1043 dollars. I thought it was all it needed but not it was not. A few days later, the car started to have the same symptoms as before, losing power again, engine slowing down and bad gas mileage... I set up another appointment with the dealership.

2014 elantra gt manual 6 speed, purchased 8/6/18 with 31,636 miles from a non hyundai dealer in massachusetts. I live in upstate ny. The car came with a 90 day or 3,750 mile dealer warranty, and is still under the factory warranty up to 60,000 miles. I'm the 2nd owner. At approx 34,500 miles, on 10/5/18, while accelerating uphill, the engine began to make a sharp and loud rapping and squealing noise and lost power. I was in heavy traffic on a country road with no where to stop, but I managed to pull over after coasting downhill for approximately one mile. I checked the engine oil immediately and there was no oil showing on the dipstick. I called my wife to come and pick me up and asked her to bring 3 quarts of sae 5-20 oil as indicated on the fill cap. It took 2 quarts of added oil for any oil to show on the dipstick, indicating that there had been significant and excessive oil consumption in the 2 months from my date of purchase, at which time the dipstick indicated that the oil was at the full level. The car had an oil change prior to my purchase per the salesman at the dealership where I bought the car. There were no warning lights on prior to the engine failure, and non came on afterward. The car is at a local hyundai dealer being diagnosed. The hyundai dealer provided me with a loaner car "for the duration", that they told me was included as part of the factory warranty and would be free of charge. I suspect a crankshaft bearing, con rod bearing and/or wrist pin failure, and seized piston(s) due to oil starvation.

Engine started with "dry (no oil)" sound, which dissipated within a few seconds. Checked the oil level, was ok. Traveled approximately 12-14 miles. At highway speed of 70-75 MPH, engine lost power. Let off the gas pedal and engine died, I pushed in the clutch pedal, coasted, then let off the clutch pedal and engine restarted making a very loud sound. Made it to the highway exit, about 1.5 miles. As vehicle slowed, it was apparent that the engine had suffered a catastrophic failure, sounded like broken bolts rolling around in the engine. Parked the car. When the tow truck arrived, there was a large chunk of metal, assumed and later confirmed to be part of an internal engine component, laying on the ground which had came through the engine block and making a hole in it. Required an engine replacement.

While driving on 5 freeway in california my 2014 hyundai elantra started to violently shake like someone hitting the brake. I threw it in neutral and help my wife turn the steering wheel because we lost power steering. We got lucky and had a space to coast to the side of the road. When we got towed to tuttle-click in irvine, ca and our car turned into the service department, they basically said we are on our own to find a ride back home and no loaner car. Two days later I have to call them to find out the problem, first a technician said that it was a bad battery but that would not have caused it to completely shut down. Then a few hours later the service manager calls to say it was the battery and that is what caused it to shut down on us. After (4) days of keeping the car, the hyundai dealership said that our battery had a catastrophic failure which caused our car to completely shut down on the freeway. I have filed a complaint with hyundai corporate but don't know what they can do?
