The worst model year for it is 2017.
On 6/12/26, the engine had a sudden, catastrophic failure that caused a life-threatening hazard on a 2-lane highway in a remote mountain grade with no shoulder. Prior to this incident, the forward collision system had falsely gone off several times in dark or rainy conditions when there was no actual hazard or oncoming traffic on the road, which is very distracting and dangerous. Hyundai is not abiding by the terms of the federal class action lawsuit settlement, refuses to replace the defective engine, and is generally a danger to the public. What is the NHTSA going to do the next time a Hyundai catches fire and causes a catastrophic disaster in Southern California? I was fortunate the engine didn't catch fire...it was lightning-hot when I opened the hood a full 30 minutes after the breakdown. This has a Nu series MPI engine...there are 5 known classes of Hyundai/Kia engines that fail without warning and the company is still getting away with endangering drivers, refusing to replace or reimburse. I have a 10k lien on this vehicle and my livelihood is at risk because of Hyundai's negligence and disregard for the law. My stalled vehicle could have caused a deadly accident when it failed had another driver failed to see it blocking the road. This is happening to millions of Hyundai owners and we're not getting the recourse we were promised. My VIN was excluded from recalls and class action, yet it has the same exact dangerous engine defect. Please investigate the Nu 2.0 MPI engine series if this hasn't already been established as an additional unsafe configuration. It would be in the interest of public safety if Hyundai went out of business; the company's manufacturing is a danger to society and Hyundai doesn't care as long as they continue to profit from consumer hardship and suffering.
NHTSA complaint #11758964 — an unverified report by a vehicle owner.
2023 Hyundai Elantra SEL. Car has been slow to start this week. When I depress the brake pedal and push to start, it will start then shut off in the middle of starting then I have to try again or it will sputter then fully start but every safety alert and electrical alarm will go off in my car and nothing clears it until I drive for about 5 minutes then they all clear. I went to AutoZone and they said my battery was normal health. When this slow start happens I also notice that my vehicle doesn’t accelerate as well and it feels like it’s trying too hard to the point it will jerk forward even when I’m only lightly pressing the accelerator. I noticed this, 2 winters ago (2024) as well and I thought it was due to the very cold weather we had. Brought it to my sister’s fiancée and he couldn’t find any DTC’s but agreed something felt off. The problem stopped and now it’s the middle of summer 2 years later and doing the same thing, to the point where I’m trying to merge onto I-95 and my car isn’t accelerating fast enough and I almost got rear ended!! It only happens at speeds under 50 and is extremely unsafe to have a vehicle where you don’t know if it will just turn off while you’re driving, stop accelerating or decide to not start that morning!!!
NHTSA complaint #11758620 — an unverified report by a vehicle owner.
The contact owns a 2012 Hyundai Elantra. The contact stated that while driving at an undisclosed speed, the vehicle lost motive power and stalled. The check engine warning light illuminated after the failure. The vehicle was taken to an independent mechanic, where the vehicle was diagnosed with a failed crankshaft sensor. The vehicle was repaired; however, the failure reoccurred. The vehicle was taken back to the independent mechanic, and the contact was advised to take the vehicle to the dealer. The contact was informed of an unknown recall; however, the VIN was not associated with a recall associated with the failure. The dealer was made aware of the failure. The contact was informed that the repair was not covered under warranty because the mileage was 3,000 miles over the mileage limitation. The vehicle was scheduled for a diagnostic test with the dealer. The vehicle was not diagnosed or repaired by an independent mechanic or dealer. The manufacturer was not made aware of the failure. The failure mileage was approximately 151,000.

The engine mounts on this vehicle failed. Dealership and many others online have stated that this seems to be a reoccurring issue with the 2021-2023 generation of Hyundai elantras. The vibrations of these failed motor mounts become so severe that they can dislodge the brakes making it very unsafe to drive. Hyundai should be doing a recall for this to avoid safety issues for their customers

An independent mechanic was contacted. The vehicle was taken to an independent mechanic where it was diagnosed and determined that the engine needed to be replaced. The engine was replaced, and the vehicle was repaired. The manufacturer was not notified of the failure and referred the contact to the BBB to report the issue. The approximate failure mileage was 108,404.
NHTSA complaint #11757404 — an unverified report by a vehicle owner.
Vehicle stalled while driving on a highway without warning. The car was able to start back up, would go a few feet and stall again. Had it towed to a Hyundai dealership to repair. They replaced the exhaust camshaft and timing components. They released the car, saying it was fixed. Less than 12 hours later, the car stalled again while driving through Washington DC. Once again, it would start up again but stall every few feet. We took it to another Hyundai dealership. They replaced the oil pump (saying the oil pressure was too high). That did not fix the issue and the dealership stated that the intake camshaft needed to be repaired. The third party warranty company would not approve that repair, as they are saying the engine needs to be completely replaced. We bought the car in March. The first incident occurred in June and the second incident was 12 hours later. The car has been at the dealership for 'repairs' ever since.

At 105,000 MI. My car stalled out and the engine stopped. It needs a new cam shaft, timing chain set, cam phaser and timing cover. We also had to replace the Variable valve timing solenoids as the metal melted.

On July 13, 2026, my engine light came on and I don't understand why. My oil change was update and not sure what else can be wrong. So, I went to AutoZone so that can do a diagnostic and they gave me a printout of the problem. Took the vehicle to the shop gave him the printout from AutoZone so that he will know what the problem is. Brought the part and that didn't take the engine light off and I paid $300 for nothing because I am still experiencing the issue. I took it back to the shop and the guy said that I need to replace my engine. I have had the car for about three years and not understanding why the engine needs to be replaced already. Then the passenger seat belt light keeps going off when there's no one sitting in the seat. I think there's a problem with the engine and my seatbelt light, but there's a recall on the vehicle. I replaced the air filter like it was suggest to me the car dealer where I purchase the car from. So, I did that and the car is running a little loud at times.
NHTSA complaint #11754355 — an unverified report by a vehicle owner.
About two months ago, I had to replace the camshaft on my vehicle. Then about 3 weeks ago while driving down the road I began to hear a grinding slap near the front right of the vehicle. Then the power died and the vehicle limped into a parking lot. After stopping for about 30 minutes, I was able to restart the vehicle and get it home. The same noise occurred the whole drive. I couldn't start it again, and had it towed to my mechanic. The mechanic's review showed that the engine had seized up despite only being down a quart of oil. The engine was getting plenty of oil to give him confidence that missing oil wasn't the cause of the problem. The vehicle has about 104000 miles on it. To date, Hyundai refuses to even acknowledge that it's their problem despite a similar recall (21V301000) already being announced for this Elantra model.

While the car is in drive, it would power off in the middle of driving. Took the car to repair and advised regarding the engine. My safety was at risk because I loss power to operation the car in the middle of traffic, which could have called an accident for myself and others. The problem have been confirmed a repair shop. No, the manufacture stated since my vin # is not included in their recall, it will not be cover but clearly its something wrong with the car. When the engine light came on, I took it to the repair shop and was advised regarding the engine.

The engine failed for my 2019 Hyundai Elantra. We bought it at Atlantic Hyundai dealership. They used a passing recall inspection to clear a defective engine, misdiagnosed the ensuing failure as an oil pan leak, and abandoned me with a vehicle that stalled dangerously in traffic. We brought car to Atlantic Hyundai told them that the car just stopped on the highway in the middle of driving. Our mechanic told me to tell Hyundai the car was rapidly consuming oil. Hyundai said oh no it’s just an oil pan snd we trusted them allowed them to fix it. Several weeks later the car completely stopped in middle of driving on exit ramp. Police came to make sure traffic was diverted so they could help me get car to side of road safely. It was towed back to my mechanic who said same exact thing car is dangerous bring it to Hyundai they need to fix this for you it’s the engine recall. We had it towed to dealership and after 2 weeks they said oh yeah you need new engine. We brought it to independent mechanic because Atlantic Hyundai knowingly sent me off in a dangerous vehicle the first time and no longer did I trust them with safety of myself and others on the road

The car was driving on the highway and out of nowhere the car just stopped in the middle of the highway. I brought it to my mechanic who said the car was rapidly consuming oil and my cars engine was seizing. and he safely brought me and the car to Atlantic Hyundai where I had bought the car to have them diagnose and fix the issue. After several days they diagnosed the issue as a simple oil pan issue and replaced the oil pan and sent me on my way. The same issue with the engine seizing up in the middle of driving on the highway endangering my life and others. I am still terrified thinking of this. We brought car back to Hyundai by tow truck because I was scared to drive it and after 2 weeks of waiting they then told me the car needed new engine however they never mentioned what I later discovered was a serious recall for this specific engine . Upon further research my car was listed under the recall however before I bought the car it says it passed the test to see if it needed engine replacement under recall 203 . They knowingly said my vehicle was safe they sold it to me knowing it was unsafe and then they put a bandaid ( oil pan) and sent me on my way knowing I was in danger. I am lucky to be alive because the car stalled out on a major highway .
