2014 Hyundai Elantra Engine Problems

the car only has 76000 miles on it. there are no check engine lights and the oil has always been perfect and changed on time. There is a known issue apparently with Piston slap that will lead to engine failure. Hyundai refuses to replace the engine, knowing the issue. Driving it puts my safety and others at risk. the Hyundai dealership in Merriam KS has confirmed the issue.

Noticed symptoms about a week before I had it towed to a garage for what I thought was a timing chain tensioner, Tech scoped it and found out it was much worse.

Engine is burning too hot its burning though oil. Oil change sept 3rd 2025 and by nov 7 2025 car had NO OIL. this is an oil burn off issue with the sport engine in this model Elantra. i cannot get an oil change every month. that is ridiculous. this time it caused my car to have flashing engine light due to insanely low oil after just TWO MONTHS. i only drive 60 miles a day. shop told me in april15 20205 i had an oil leak and they fixed it, resealed again in july cuz the oil was still going low. now they told me nov 11th they did a test and the engine is running too hot and is burning off the oil.

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 in my car (Hyundai Elantra gt 2014) basically did everything I read about all the other Hyundai engines doing that are under engine recalls. Years ago it started having misfires, had the catalytic converter or parts of it replaced, sensors, over consuming oil, loud noises when it's lower on oil and eventually it just recently died. Unfortunately it's only 11,000 miles over the extended warranty period to get it replaced. The bad engine stuff basically broke the current catalytic converter and the dealership wants over 10,000 dollars to fix it and replace the engine... not including tax. The worse part is sometime like a year ago I went to a dealership because I had an apt for an oil change. The day before my check engine light turned on. So at the apt while checking in my car I mentioned to the guy taking photos of my car that the check engine light was on and please check it out. I waited two hours for them to give me my keys back and say I didn't make the appointment for the check engine light so they couldn't see what was wrong with it that day. And that had never happened before. At the time I had only been to dealerships to fix my car and The dealerships always agreed to check out the engine light when it was on except for this one time. Felt like I was getting pushed out the door. So I've spent the last year going to other mechanics attempting to fix the check engine light and it always just came back on when I got my car back. Tune ups, spark plugs, cylinder misfires. Elantra GT's are not represented in any of the recall articles I read about online so I felt the need to share my story because I think my car had the same engine as some of the other cars. RIP Elantra GT

When I had near 50,000 miles on my car, my car emitted lots of smoke (like severe burning) from the back when I drove on highway. I had to immediately take the car to Hyundai service. They said nothing is wrong with engine. Years later, I started hearing knocking noise from the front and got engine light on twice in the past. The last time was 3 days ago when I drove to the local airport to pick up my son. Someone inspected my car yesterday because Hyundai had no availability until the next month. He advised me to take the car to Hyundai as soon as possible. I took it to Hyundai service and they said nothing is wrong just like the last time years ago. He told me oil was leaking inappropriately and damaged the motor inside. He informed me this is normal with Hyundai vehicles as they used GDI engine. Today Hyundai service charted me the inspection and said nothing is wrong with the engine. I told them I brought the car because knocking noise and engine light. I shouldn't pay even though they found nothing is wrong with the engine. I feel.very unsafe with driving this car. The guy who inspected the car said the motor is damaged due to the engine defect and excessively burn oil. They attempted to charge me for what Hyundai is responsible of ensuring the safety affected by manufacturing issues. Thank you!

roughly 5 months ago i started to hear a ticking/knocking sound. since then it has gotten louder and the car is having issues accelerating. Hyundai refuses to fix it even thought they’ve had a class action for this exact issue.

Scored cylinder walls and needing a full motor replacement before the engine just seizes

I was driving home on april 13, 2023 when the power seemed to leave my car & steering & brakes felt like they weren't working right like I had no control. The battery & oil change lights came on. I was scared & didn't know what to do but then a min or so later I was able to get enough control to direct it into a parking lot across from my house & turned off the engine. When I turned the car back on the 2 warning lights were gone & I was able to drive it across the street. I had been hearing a noise under the hood & wasn't sure if it was a belt or something. A mechanic said the belts, hoses etc were good but he thinks that noise was my engine rod bearings going & he had dealt with more Hyundai engine problems recently. I had Hyundai dealership check my engine & they said my connecting rod bearings are bad & I need new engine. They said this is not covered under their extended warranty & I am over the warranty miles & they won't help in any way. This is a bad engine & I have met other Hyundai owners in same situation. & it wasn't until I read an article where another Hyundai driver experienced the same thing I did on April 13 before her engine died on a highway that I connected that event with a bad engine so I believe that is what happened to me on April 13 except my engine didn't completely die on me. This is a safety issue if a car engine stops working while driving on a road. I have receipts from everything I have done to my car & you can tell it wasn't lack of care that caused this engine failure. It is engine defects I believe are causing them. Please investigate the problem & keep Hyundai & Kia drivers & drivers around them safe. And get Hyundai to do right by their customers & replace these defective engines. I can show invoice where Hyundai declined providing assistance because of miles as 2nd owner but service man only hand wrote problem with engine was connecting rod bearings on it. He didn't include it on printed invoice. Hyundai has photos & info.

My 2014 Elantra has a blinking check engine light on. This is an ongoing problem. The dealership diagnostic keeps saying that it is a misfire and I have paid to have it fixed. Change all the plugs twice and the check engine light is back blinking. I can't drive it at all. Each time this happened I was in the middle of traffic when I was forced to try to pull over. Very dangerous situation.

The oil light is blinking and car repeatedly shuts off while driving mostly when going 25-45mph. When it shuts off I have to turn it off take the key out and turn it back on until the next time it happens. This usually occurs within an 20 minutes of driving. My safety was at risk because of other cars behind me going speed limit while car automatically shuts off. Car was bought on carvana no local dealer but have taken it to multiple shops and they are shocked to hear of no recall. The car has not been inspected by police insurance but local mechanic shops. Oil light blinks while driving constantly from start to finish while car shuts off steady oil engine and battery light on.

ENGINE STALL WHILE DRIVING TWICE . ENGILE OIL WAS SERVICED 3 DAYS BEFORE THE INCIDENT . OIL LEVEL IS GOOD OIL INDICATION WAS FLASHING FOR 3 SECONDS WITH ENGINE TICKING BEFORE STALLING. LUCKILY I WASNT DRIVING ON THE HIGHWAY . A CAR SHOULD NEVER SUDDENLY DIE WHILE DRIVING WITH NO WARNINGS .

I PURCHASED THE CAR AT A USED CAR DEALERSHIP. I DROVE IT HOME AND THE NEXT DAY THE ENGINE LIGHT LIT UP AND IT STARTED TO RUN ROUGH. WHILE DRIVING IT DOWN THE ROAD THE CAR SHUT DOWN AND I COULD NOT EVEN GET IT OFF THE ROAD. I HAD IT TOWED AND THEY AGREED TO TAKE IT AT THE HYUNDAI DEALERSHIP. AFTER RUNNING DIAGNOSTIC ON IT THEY TOLD ME I NEEDED A NEW ENGINE AND THAT THERE WAS NO RECALL AND THAT IT WAS NOT COVERED UNDER WARRANTY. AFTER PAYING 9500.00 FOR THIS VEHICLE AND IT DYING LEAVING ME STRANDED ON THE ROAD. I HAVE NO VEHICLE.

Hyundai has had numerous engine failures and fires, due to piston slap. Multiple lawsuits and recalls in other countries. Hyundai has a T6G service campaign to replace these engines and they even extended it to unlimited mileage for the first owner. The problem is that they will not honor this unless you are the first owner and you did all of your oil changes at the dealership. They have an 85% rejection rate for claims that have the eligible flaw... That is ridiculous. Why are they able to refuse to fix 85% of these engines that blow up and catch fire prematurely due to a known issue? Please recall these engines. Multiple times my engine has stopped leaving me with no power steering or brakes, one of which almost ended in a collusion on the highway. It took a lot of strength to push the break in to stop the car. The scariest moment of my life. And I knows these are an issue and the dealership even said he sees a bunch of them come in all the time with this issue, and yet until it is an actual recall and I will do nothing about it. Please please for the love of God issue a recall on these, thank you so much NHTSA for keeping automotive industry in check and making sure that our cars are safe and reliable.

My engine has a hole in the block and the starter completely blew up. Noone can explain how this has happened. The car shop wants $12,000 to repair this. The car never leaked any oil until the day it blew up on me. No check engine light ever came on, no oil light ever came on.
