2018 HYUNDAI ELANTRA Engine Problems

I have a 2018 Hyundai Elantra with about 155k miles. It has been consuming oil excessively and has developed serious drivability issues. If I try to accelerate even slightly harder than normal—especially above 2,000 RPM—it makes a metallic, chain-type rattling noise, loses power, and produces heavy smoke from the exhaust. The smoke sometimes continues even after shutting the engine off and restarting. Because of this, I’ve been avoiding rapid acceleration and slowly working up to highway speeds. The car also periodically shakes at idle, idles higher than normal at times, and the RPMs will occasionally rise on their own. In the past it has stalled randomly, and sometimes it feels like the transmission is “stuck” and won’t shift properly. Despite all this, there are currently no check-engine codes. This is terrible and clearly there’s been lawsuits and other recalls regarding the same issue and same engine but nothing for mine? I am out of warranty and had no clue the amount of issues the car was going to have until last year and I’m screwed now, insurance doesn’t cover issues with the engine or transmission. Neither will Hyundai?! Last year Hyundai performed a CVVT repair that cost about $6,000, which temporarily improved things, but the symptoms returned shortly afterward. When I brought it back, they said they couldn’t recreate the issue. The car is now out of warranty. Separately, the car was stolen two months ago due to the immobilization fault and TIk TOKs videos and the police said it has been hundreds of these Elantras stolen and destroyd and the ignition and wiper control switch/harness were damaged, which still hasn’t been repaired.

What component or system failed or malfunctioned, and is it available for inspection upon request? The car began stalling and started to become unresponsive while I was driving to work. While I was not 100% sure of what component was malfunctioning at the time, I suspected that it might be a timing chain problem because I had this same exact issue happen to to this car back in January 2025. I did not expect this issue to occur again because at the time of the previous problem, the dealership confirmed that issue was the timing chain and the VVT system, and replaced those components with new parts. How was your safety or the safety of others put at risk? The car started stalling and sputtering, then became unresponsive while I was driving. If I were in a high-traffic area, I'm not confident that I would have been able to accelerate, stop, or safely pull over to the side of the road without putting myself and/or someone else in harms way. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes, the car is currently at the dealership and they confirmed that the issue is the timing chain and the VVT system. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? Yes, the car is currently at the dealership and they confirmed that the issue is the timing chain and the VVT system. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? No, there were absolutely no warning lights, messages, or symptoms prior to the failure.

It is showing signs of excessive oil consumption. 200 miles before my next scheduled oil change there was no oil in the car, causing overheating issues. It uses the same engine as other recalled years for the same issue. However they never issued a recall for the 2018. The only update I've ever received was a surprise notice from Valvoline, mid oil change, that if I didn't use the more expensive oil change option, which I couldn't afford in the moment, that I would void any warranty from Hyundai. There was no prior notice or contact from Hyundai informing me of this "New" (the valvoline tech's words not mine) policy. So not only is my car experiencing an issue known to affect this engine, they get to absolve themselves from responsibility by surprising someone with a greater expense than they are expecting, by not giving notice to their customers? This doesn't seem fair and needs to be addressed. Since that first visit I have followed their recommended oil change specs and still have excessive consumption. The date I'm giving is the approximate date of that first visit to valvoline when my car had no oil and I was told mid change about the new policy.

Initial Fault Code: P0303 Replaced all 4 spark plugs and all 4 ignition coils. The check engine light extinguished momentarily but returned, logging P0303 and a new P0301 Replaced all 4 fuel injectors. CEL extinguished momentarily and then returned, logging P0303. Replaced the entire engine electrical harness. Concurrently, all related electrical components and connectors were meticulously cleaned with professional contact cleaner. CEL extinguished for significantly longer period of time, and then returned, re-logging P0303 and P0301. Thid suggested the ECU was "handshaking" with new components but re-logging the fault upon detecting the persistent core issue. A full compression test was performed. All cylinders reported results within specification. Using a borescope I inspected cylinder walls in piston tops. There was significant carbon residue buildup but nothing out of the ordinary for similar GDI engines. I still performed a PEA GDI specific chemical cleaning. It was a a little smoother afterwards, but the misfire persisted and CEL remained on. I also removed, cleaned, and tested common sensor faults, with no result. Also p0128 code and no start / electrical drain, and engine light started flashing numerous occasions had to stop the vehicle. I tried swapping the coils, but all that proved was that the coil was good, I did a power and ground test, it passed the connector had 12 plus volt power and a perfect resistance to static ground. The signal wire from the coil connector had perfect continuity to the ECU but had OL to chassis ground showing there was no short. A test light was used to see if anything was coming from the signal wire to the ignition coil and that test failed, there was no signal pulse. The diagnostic process has definitively proven a component-level failure inside the engine control unit. See attached file for more detailed information.

My engine blew in September 2024. I had it replaced. When I replaced it I got a one year warranty and unlimited mile warranty. It now blew in July 2025. I have had it hyundai of mankato which they didnt want to wait on hyundai of America to do anything to fix it and told my mechanics to have my car get offline their lot. My mechanics towed my car to Happy Hyundai of Rochester. HYUNDAI of America will not accept my warranty now and just pay for the new motor, tear down, and the time they have in it. Hyundai of America told my mechanics if they took it from Hyundai of Mankato and brought it to another dealership that they approve of that they would accept my warranty and pay for all parts and everything. Hyundai of America picked Happy Hyundai of Rochester. Where my car is.

Excessive oil consumption. Engine completely dry after 3500 miles in between oil change with no check oil warning light

In early May 2023 I was driving my 2018 Elantra vehicle on the expressway. I had hot an area where there was traffic and had to slow down and move along with the speeds everyone else was going. When I slowed down my engine quit. Everything turned off and the car was stalled. I was able to turn the car back on and start the engine but there was a loud knocking sound coming from the engine and when applying my foot on the gas it wasn't going anywhere. It stalled in traffic again. I put it in park, and restarted it and got enough gas for it to move and get off the main road. I called a tow company and had a certified mechanic take apart the engine $600 and Inform me the engine was shot. The car had maybe 80,000 miles on it. I had no idea what to do. The car sat at the repair shop for several weeks while I figured out what to do. I had it towed to a Hyundai dealership and had them look at it. They told me that there was no recall and that since I wasn't the original owner their powertrain warrenty was not valid. They did their diagnosis, another $300 just for them to tell me the same thing the other mechanics told me, the engine was shot and needed to be replaced. They put together a list of items that needed to be replaced and repaired and it came out to over $17,000 and Hyundai would do nothing for me. A vehicle with less than 80,000 that's engine fails is a recall in my book. It's now been over 2 years and I continue to pay for a car I cannot drive, and Hyundai still doesn't accept responsibility. This is a faulty car and would never recommend to anyone. Look at all the complaints regarding the engine and powertrain, obviously this is an issue. Hyundai needs to acknowledge this and replace these failing engines. Maybe by the time I'm done paying this car off they will take responsibility and the NHTSA will fully support the individuals that are owed a vehicle or engine replacement.

We were heading back to Ohio at Mile marker 8 75N Kentucky when we heard a boom. Then we saw smoke as my husband was pulling over. We jump out to get our child out of the car seat and at the same time a pickup truck pulls up with two guys. They yell that our cars on fire and began putting the fire out with a fire extinguisher. We had an oil change before we left Ohio by Valvoline. This area of the hwy isn't really patrolled and only has a volunteer fire department. A constable just happened to pass by US on the way to Indiana.

Oil consumption will cut off while driving

The engine of my 2018 Hyundai Elantra has a rod bearing defect covered under a safety recall. The vehicle has not been repaired yet, and the issue prevents the car from being safely operated. I have incurred towing expenses due to the inability to use the vehicle, and I am concerned about potential engine failure or safety hazards if the defect is not addressed promptly.

The dealership replaced my engine and spark plugs when the pistons were grinding metal causing a catastrophic failure in November of 2024. In July of 2025 I started experiencing the same issues and the dealership stated that Hyundais ignition coils have a high rate of failure because they changed the design and used my old ones from my engine replacement. It is now I brought my car into the dealership July 18th and they stated that was their best guess but they didn’t now forsure. I was never informed of the high rate of failure until I was experiencing it.

Oil leaking from pistons in engine just like the recalled engines

I purchased a 2018 Hyundai Elantra on April 3, 2024, from CarMax. At the time of purchase, I was not told about any recalls. Later, I discovered that my vehicle is covered by Hyundai Service Campaign 993 (Anti-Theft Software Upgrade), issued February 13, 2023, which addressed the lack of an immobilizer in 2011–2022 Hyundai vehicles. On May 29, 2025, my vehicle was stolen due to this defect. When it was recovered, it had a blown engine and was completely inoperable. Hyundai acknowledges that my VIN is included in the recall, but they have only offered to install the software update now. That does not remedy the damages caused by the theft and resulting engine failure. CarMax has denied responsibility, claiming they were not aware of the recall. I am now left with a financed vehicle that is not drivable and has lost significant value due to Hyundai’s defective design.

Burning oil. Multiple misfires. Replacing spark plugs more often than should have to. Engine knocking.

The crankshaft needed replacement The oil pump broke at 107,000 miles

I started my vehicle and it was running sluggish and low idle. I had an engine light and when I tried to drive there was a clanking sound. When I had the engine light tested I received the following codes: P0017 - Crankshaft Position Correlation Bank 1 Sensor B, P0303 - Cylinder 3 Misfire Detected, P0302 - Cylinder 2 Misfire Detected, P0301, P0014 - Exhaust Camshaft Position Timing - Over Advanced (Bank 1), P0030 H02S Heater Control Circuit (Bank 1, Sensor 1) I had it towed to my nearest Hyundai dealer in Tacoma, WA. After they did a diagnostic they said that they would have to replace the engine due to a shearing of a pin, leading to the belt jumping and causing issues. I am the only owner of the vehicle, I have had all my oil changes on time and my vehicle is 137,000 miles. This should not be happening in a vehicle with such low mileage. In reading online, this is an issue that Hyundai is aware of but not concerned with. There was no warning beforehand. This could have led to my engine stalling on the the freeway at freeway speeds and thus could have caused a great accident and bodily harm to myself and others. Hyundai has denied responsibility but knows this is an ongoing issue with it's poorly manufactured engines. I was not informed of all the problems of Hyundai vehicles before I purchased mine. I have yet to receive help from Hyundai Customer Service or the Hyundai Dealer.

Burning oil internally. Adding 1 quart about every 1000 miles.

Formal Complaint: Engine Failure in 2018 Hyundai Elantra To Whom It May Concern, I am submitting this formal complaint regarding a severe and unresolved issue with my 2018 Hyundai Elantra, which has been problematic since the time of purchase and has now suffered a complete engine failure. Despite regular maintenance and responsible use, the vehicle has proven to be unreliable and unsafe. 1. Nature of the Problem The most recent and critical issue involves total engine failure. On May 12, 2025, I brought the vehicle to North Freeway Hyundai due to the car not starting. Their official diagnostic report revealed that the engine needs to be replaced. Additionally, the inspection showed issues with the transmission cooler coolant lines leaking, EFI system, camshaft exhaust, radiator hoses, and the battery. These problems affect essential systems that are critical to both the performance and safety of the vehicle. 2. History of the Problem From the beginning, the vehicle experienced a series of mechanical issues. These included engine stalling, warning indicator lights, rough idling, and decreased fuel efficiency. I consistently took the car in for service and maintenance, yet the problems worsened. In the days leading up to the failure, the vehicle had trouble starting, made abnormal noises, and eventually stopped working entirely. 3. Risk to Safety The failure of the vehicle to start without warning has placed me in unsafe and potentially dangerous situations, including being stranded in public places. The risk of the car stalling during operation could have endangered not only my safety but also the safety of other road users. This is a serious safety concern that should not be ignored. 4. Diagnosis Confirmation The diagnosis by North Freeway Hyundai confirmed that the engine failure is complete and that replacement is necessary. The service notes also included a recall campaign (24-01-009H-1) for anti-theft software and decals. These issues further demonstrate

I am filing this Vehicle Owner's Questionnaire (VOQ) regarding critical safety defects in my 2018 Hyundai Elantra related to: - Recurrent ignition coil pack failures (3 replacements since 10/2018) - Engine stalling at low speeds (6 incidents since 10/2018) - Dealer refusal to apply TSB 20-01-008H ECM update despite matching symptoms Technical Background: Hyundai Technical Service Bulletin 20-01-008H (February 2020) specifically addresses: - Misfire detection logic flaws in 2018-2019 Elantra 2.0L engines - Required ECM software update (ROM ID AD8SP2AS673D) - Updated ignition coils (P/N 27300-2E601) Safety Incidents: 2025: Stalling event at 25 mph approaching traffic light (no crash) 2021, 2023, 2024: Multiple misfire codes (P0300-P0304) with check engine light Dealer Interactions: - Round Rock Hyundai refused ECM update on 05/2025 claiming "VIN not in campaign" - Round Rock Hyundai refused coil replacements on 05/2025 claiming not under warranty - Service advisor acknowledged stalling/coil failure pattern matches TSB criteria Formal Requests: - Investigate Hyundai's VIN filtering for TSB 20-01-008H applicability Require Hyundai to: - Perform ECM software update per TSB specifications - Replace all coils with updated P/N 27300-2E601 - Reimburse previous coil replacement costs $1700 (6 coils over 7 years) - Open recall investigation for 2018 Elantra ignition systems Attachments available upon request. I authorize NHTSA to share my contact information with Hyundai Motor America. This defect creates unreasonable safety risks through sudden power loss and compromised vehicle control.

While driving on the expressway, my vehicle suddenly stalled out. I was able to restart in but the car would not go over 25mph. I was able to pull off the next exit and call for a tow truck. My vehicle was brought to a local shop and they pulled the engine and find that it was shot. Due to Hyundai, they requested to do their own diagnostic and found the same issue. The vehicle ad less than 80,000 miles on it. I received an invoice for repairs required which was over $16,000 in repairs including replacing the engine. I pleaded that they cover the engine and this seems to be a recurring issue with this model. They refused. I am stuck with a vehicle I cannot a drive and is now sitting in my driveway with no option but to wait for a open recall.

Check engine light came on , car was sluggish and stalled on highway , was able to glide over to the side . Would not start . This is the 4th time this happened to this vehicle , in the past I was able to put in neutral and restart . They fixed it 3 times but they are now Hyundai is now saying it needs a new engine.

Check engine light came on, took to mechanic. Diagnostics showed pistons performing at half of the required psi. Engine replacement required at a cost of nearly $9,000. The vehicle only has 74k miles.

While diving the vehicle started to sputter and the ignition turned off. I was able to start it but the vehicle was making loud clunking sounds and max speed of 10mph. I pulled off on the side of the road and called for a tow to a reputable repair clinic. I told them what happened and they stayed they would be required to remove the engine to determine the issue. $$$ I paid the funds and they informed me the engine was shot. The vehicle has just over 80,000 miles. I contacted Hyundai directly and was told the manufacturer 100,000 mile powertrain warranty was invalid due to me not being the I original owner. I convinced them to take a look and make their determination. After paying out of pocket again for towing and the $175 I initial service fee Hyundai again told me the engine was shot and their was other issues alongside the engine that would need to be fixed. They gave me a quote of over $16,000+ on a vehicle that was less than 6 years old and under 85000 miles. NONE of which they stated was covered under their powertrain warranty. The vehicle is blue booked at about $5,000 and I spent less the what would be required to repair the vehicle. Hyundai has been zero help, they have not supported their product even after I was told by a reputable resalesman that there is a silent recall on this engine for this issue. Im left without a car, still being required to pay the car payment to the loan company and keep full coverage on a car that hasn't driven since early May 2024 and the insurance company isn't helping because the vehicle wasn't in a accident and is an electrical/manufacturing issue, regardless that I have loan lease payoff. I honestly need some advice. Not to mention I am a disabled veteran, Hyundai will not pull any strings. It's sad because I know this is no fault of my own and had taken care of all the vehicles needs when required (oil, tires, spark plugs, alignments ect.. what should I do??

Engine shuts off suddenly in the middle of road; several times on the way back home while my wife was driving with no warnings. Very unsafe if another car is behind. She cranked over and it went, but it happend again in an intersection after a stop sign, fortunately no cars were coming. No shows WARNING LAMPS, check engine light on or diagnostic trouble codes, but engine next day started making noises like knocking or ticking. Car is only 140k miles. Symptoms appeared 2 days ago 2/23/25

I bought my Hyundai Elantra 2018 in 2022. It started knocking by 2023 and i was told by the dealership it was plastic hitting the tire. I brought it back & had it scanned prior because the knocking never stopped. And another dealership confirmed it was the sealed transmission. There is no dipstick to check the fluid & it says in the book the fluid is good for the life of the transmission. The dealership i initially bought it from acted like it was my fault so my car sat May until August 2024. Finally, after i found out the unlimited warranty i paid for was never submitted in 2022 it was approved. They then replaced it with a refurbished transmission which i didn't know until i got my car back. I had mentioned an oil leak & lots of play in the engine that November after replacing it. They said there was no leak or play in the engine. Now in January I had died at the four way & almost coasted into the parking lot nearest to me. Mid me picking my daughter up from school. Due to the leak.

Had to do 3 oil changes in a month had to change ignition coil that had been changed a month ago spark plugs were completely covered in oil was driving and it literally just stopped every time the oil would be checked it wouldn't be any on the dipstick.

My 2018 Hyundai Elantra had an oil pressure light on and the timing chain was slapping the side of the engine. I changed the timing chain, oil pump, oil sending unit, and oil filter. When I dropped the oil pan, there was paint chips in the pan. Who paints the inside of an oil pan? I removed the oil pick up tube and discovered the inlet screen was covered with these paint chips. I cleaned the inlet and reinstalled the tube and oil pan. I no longer have the low-pressure issue. This is causing engines to have major issues and / or making them seize up. Now, I believe there are a lot of Hyundai and Kia vehicles in the junk yards today because of this very issue. Majority of people will not take their engine apart to find out why it stopped working. They ether stop paying on them or junk them. As you can see in the attached photos, you will notice the pain in the pan, inside the oil pick-up tube, how much of the screen was exposed. This is a major fault of the manufacturer and Hyundai and Kia should be held responsible for the repair.

My car lost power on a busy highway which almost caused a tractor trailer to rear end me. I had the car towed and the mechanic said the engine is bad because of issues with this engine losing oil quickly and there is no recall on it but on other years. Now I have no car but still owe money on it and can’t get to work. Luckily i wasn’t hit by the tractor trailer but this should be a recall and i should be able to get it fixed without being out thousands of dollars.

Engine seized up at 142K miles. Had regular oil changes and maintenance. Connecting rod crank shaft end / bearing blew apart and seized engine.

Engine is knocking cannot find a solution for this problem car stalls wen coming to a stop the car completely powers off , noticing a weird smell now ,

Driving on the freeway around 55 MPH the engine would stall. Scared the heck out of me this started around 130000 miles on the car. Fixed a sensor still didn’t fixed the issue did an oil change that seemed to fixed the stalling. Low oil light never came on. So for years after that when the car stalled I did and oil. change. Finally at 183000 the engine gave out. Did my research found out Hyundai knew there was a problem with the engines. On 2019 and 2020 Elantra engines have been recall. 2018 not enough complaints on th engine. There was a knock sensor recall on the car. I never got a recall notice. Sent an email to Hyundai saw that the email was received but no one has responded this was a month ago. Taking my Hyundai to the dealership to see if they’ll do anything for me. My miles are all highway miles. Engine should have lasted longer. Very disappointed that Hyundai has known that the 2.0 liter engines since 2015 has had issue over 500000 cars are effected with this issue but Hyundai doesn’t want to fix the issue. It’ll all about the money for the company producing defected cars even Kia have the same issue.

The engine experienced rod bearing failure while driving the vehicle. The vehicle died on the road in a high traffic area, which put me and others at risk as they tried to maneuver around the car and as I tried to get the car off the road. The car had just had the oil changed, and had consistent/regular maintenance. No warning lamps lit up on the dashboard at all until the engine died, at which point the oil indicator lit up. The vehicle has been taken to Hyundai and confirmed to have rod bearing failure, a known issue with engines in Hyundais and Kias.

Hyundai engine from 2017 and up are not good engines my experience on my 2018 Hyundai engine is the same as what I see 90 percent of Hyundai owners are having regardless of the year there all the same engines it’s burning oil it’s making ticking noise with regular maintenance no neglecting y’all have to understand there are so many ways and possibilities of engine premature failure then it is Maintaining the engine during buliding these engines you have metal particles over tighten the heads the blocks not seating the piston rings properly dirt that can clog up the oil galleys to luberciate the moving parts poor design there’s so many ways to say it’s not a manufacturer defect and they tell us change the oil ok how come I’m having more issues and hearing issues from a engine then the transmission you do more maintenance on a engine then a transmission these transmission are not the problem you are hearing engine problems even when people do maintenance so sounds to me the manufacturer should recall 2018 models as well it’s beyond me for you to skip a year and say that model isn’t having issues it’s definitely happening in 2018 models as well the transmission is fine I never heard or experience and transmission failure in these cars when there are a lot of people complaining about a similar issue in the same model car at that point it has to be a issue manufacturer aspect we’re told as consumers and vehicle owners change your oil that’s it there’s no way I should be dealing with major issues on a simple solution you don’t hear Toyotas breaking down Hondas breaking down with regular maintenance oil changes you hear Hyundais engine all across the board and it is a safety issue going on with these cars not just 2017 2018 engine it’s ticking because lack of lubercation the manufacturer could have left metal particles in the engine could have warped heads over tighten bolts dirt that was already in those engines a bunch of causes poor design I really hope they replace it

This has happened a couple of times where in the middle of driving, my car automatically shuts off, I can not turn my steering wheel I can not push the brakes, everything stops working. I have to wait till my car comes to a complete stop on its own, put the car in park, turn off the ignition, turn my keys and start my car again. Then it sometimes acts like there is no power to accelerate when I'm at a full stop. RPMs go crazy, but acceleration doesn't occur. No warnings have ever come up. I received an notice about a recall, but it's for 2019 Elantra and up. Mine is a 2018, but the issues for that recall is the same thing that is happening with my car. This is DANGEROUS and can lead to serious repercussions or even death. Something needs to be done to fix this. I don't not have thousands of dollars to pay for an issue with the manufacturer.

About 4 weeks ago (mid-May) I was driving in stop and go traffic on a major highway. My car is a 2018 Hyundai Elantra, manual transmission. After about 30 minutes of this, the car started to just cut out, the engine cut out when I was changing gears. It did this about 6 times on my drive home. I noticed that when the rev meter got below 1, the engine would just stall out, so I tried to give it gas to keep the revs up. In addition, the engine was making a knocking sound. I took it to my mechanic's the next day and when he heard the sound, he said it needs a new engine. He has had a few customer's with similar issues with their Hyundais. He told me to tow it to the dealer and they would help me get the engine replaced. That same day, I had it towed to a dealer nearby. They charged me $195 for a diagnostic and said it needed new spark plugs and replaced cylinder 1 coil, which they did. ($900) I picked it up, but I could tell it still wasn't right. The mechanic assured me he fixed it. However, they also told me the "check engine" light was on (it wasn't). When I was driving it, it started to stall again when I was changing gears. I brought it back to the dealer, he told me his mechanic had trouble getting it into reverse, there was a problem with the clutch. He would need to "tear down the transmission" for $2,000 and even then, he wouldn't know what the problem was. This just didn't feel right--I got the impression they didn't know what they were doing and that this mechanic couldn't even drive stick. I took it back to my own mechanic who couldn't find the problem. He told me to drive it around and when it makes the sound/cuts off, to bring it back. I drove it home--today--and the knocking sound started after 15 minutes. I recorded it and texted it to my mechanic. He called me and said "it's the engine. the dealership mis-diagnosed your problem and overcharged you." I called a different dealer, got an appointment for next week and must play the $200 diagnostic .

May 24 2024, while driving on Interstate95 at approx 70mph, I experienced catastrophic engine failure, with metal shards and screws shooting out, oil spewing, and smoke billowing everywhere. Loss of control of vehicle and nearly hit by passersby while trying to guide vehicle to swale. There were absolutely no warning lights or signals, and vehicle had just been serviced at Hyundai dealership at 77k miles (odometer reading 81k at time of incident). Independent mechanic diagnosed engine failure, hole in block, and provided attached photos. Vehicle was towed to Wallace Hyundai, in Ft Pierce, where it awaits dealer mechanical inspection.

I was driving about 45 mph when the car just turned off the first time. I was able to put it in neutral and start it back up to get to the side of the road and it died on me again. I was about 30 feet from my destination at this point so I got it where I was going and turned it off. When I turned it back on it was making a terrible knocking/grinding noise. It didn’t have a drop of oil in it (about a thousand miles after my last oil change mind you) so I put oil in it and started it again and the sound quit. I went to drive it and it died before I could accelerate to a decent speed, got it cranked and rolling again and it slowly got up to 40 mph, but the second I started to slow down again it would die. So I had it towed to my mechanic who at first thought it was because the timing chain had a lot of slack in it, assuming it jumped time so he changed that, but it was still dying. He ended up finding the cause to be the exhaust cam sprocket? I’ve never heard of this before but I do know that ever since I bought the car 3 years ago it never felt like it would get up and go whenever I hit the gas. Since I picked it up from being fixed, this thing zoom zooms everywhere now! But it is still using an ungodly amount of oil between oil changes.

Mileage: 136,000

I am losing engine oil all the time to the point the car engine shut off My engine start losing oil after 2000 miles 1000 miles before oil change [XXX] [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The contact owns a 2018 Hyundai Elantra. The contact stated that while driving at 70 MPH, the vehicle made an abnormally loud popping sound. Two other drivers alerted the contact that flames were coming from underneath the vehicle. The contact checked the rearview mirror and noticed smoke coming from the vehicle's rear end. The steering wheel then seized, and the vehicle lost motive power. The check engine and several other unknown warning lights were illuminated. The contact pulled over to the side of the road and exited the vehicle. No injuries were sustained, and no medical attention was received. The flames extinguished themselves. There were no police or fire department reports filed. The vehicle was towed to the dealer, where it was diagnosed with a seized crankshaft and determined that the engine needed to be replaced. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was 224,809.

Mileage: 224,809

AT LESS THAN 62,000 MILES THE ENGINE NO LONGER HAS PRESSURE AND THE CAR IS INOPERABLE. VEHICLE BEGAN STALLING 1 WEEK PRIOR TO CAR BECOMING INOPERABLE.

ON THE FREEWAY GOING ABOUT 45 MPH TRIED TO SPEED UP AND SWITCH LANES AS I PRESSED THE GAS YOU CAN HEAR THE ACCERATION BUT THE CAR DIDNT INCREASE IN SPEED THE WHOLE DASHBOARD WENT BLANK (BLACK). CAR WAS UNRESPONSIVE. ITS VERY DANGEROUS THAT THE CAR FALFUCTIONS IN CRITICAL CONDITIONS LIKE BEING ON THE FREEWAY. YES I HAVE TOOKEN IT TO HYUNDAI AND THEY NEVER FIND ANYTHING WRONG. ALSO AT TIMES THE CAR WONT EVEN TURN ON. NO TYPE OF WARING LIGHTS ON DASHBOARD.

Having issues in several instances the past few months , where my car abruptly stalled in highway traffic, again less than a month later while at a stop light, traffic built up, I became nervous an scared, finally after turning my car off an on several times I was able to get my car to stop stalling an drive away. Third instance has been the ammount of oil consumption my car is needing, I’ve noticed an increase use of oil for my car I use as a daily driver just commuting to a from work, an a clicking/knocking sound, other instances was my car accelerated at high rates of speed on the freeway on its own. Only after smash the break button was I able to disengage the throttle. An now just recently my car is using up more an more oil an has developed a hard knock in the engine. Similar to other models that have been recalled for the same reason. Reading online has made it clear thousands an thousands of other people are having issues just like mine around the same mileage as me an other models that have had the problems

Unfortunately I bought a Hyundai Elantra sport brand new in 2018 i’ve kept the maintenance even to this day the car currently at 147,300miles. However I started having issues at 30,000 miles check engine would go on the car with shake and stall and miss fires would occur frequently. Every time I took it to the dealer they reset the computer but never made an actual note of what was going on with the car. That dealership that I took it at the time was Universal Hyundai in Orlando, Florida. So now that I have 147,300 miles the same misfires are now catastrophic failures on the same cylinders, to add insult to injury I took it to a different dealer located in Sanford Fl so they can try to get willful engine replacement, and my claim was denied because I was out of warranty and over the mileage, the dealership new that I was both over mileage and out of warranty the second I brought the car in somehow I still get charged $213. It seems like no one can do anything about it cause Hyundai America made there decision to deny my claim. These cars are straight up trash my buddies Kia similar situation has made it to 150,000 before he had total engine failure engine seized up on him. To make things worse I’m making payments on a car that’s needs an engine replaced. I’m never buying a car from Hyundai ever again they’re straight garbage and now I have to purchase another vehicle. Thanks Hyundai America for making unreliable vehicles and then taking my $213 to just deny my claim despite having a perfect maintenance record. I hope people read this and realize what crooks you guys are. Side note Hyundai America refused to help, however when I threatened to contact the BBB to complaint about there product the customer service agent Ciani mentioned they will open up case as to why I’m putting a complaint to the BBB, I don’t know what the outcome of this will be but it’s irrelevant I wouldn’t take a free Hyundai even if it was given to me! You lost another customer for life!!!

MY 2018 HYUNDAI ELANTRA WENT FROM 50 MPH TO 0 IN SECONDS. I WAS ABLE TO COAST TO THE SIDE OF THE ROAD. THE ENGINE SHUT OFF. THE ENGINE AND OIL LIGHTS CAME ON . CAR DIDNT TURN OVER AFTER THAT GOT IT TOWED TO MY HOUSE AND ONCE THERE CHECKD THE OIL AND THE OIL WAS COMPLETELY EMPTY. RECEIVED MY LAST OIL CHANGE ON 1/31/2024 STILL HAD MILES LEFT OVER BEFORE GETTING ANOTHER OIL CHANGE. THERE WAS NO WARNING OR SIGNAL NOTIFYING OF OIL LOW OR ANYTHING AFTER SPEAKING WITH SERVICE MECHANINC THEY MENTIONED THE ENGINE BEING SHOT. THERE IS NOT EVEN 100,000 MILES ON THIS ENGINE AND IT NEEDS A NEW ONE. CONTACTED DEALERSHIP THEY ADVISED NO RECALLS ON THIS MODEL. HOPEFULLY ADDING ANOTHER COMPLAINT CAN GET THE BALL ROLLING SO THERE CAN BE A INVESTIGATION.

I got this car like 5 months ago and after driving it for 2 months I had to get a new engine for 4500 dollars. There is no way it can go bad in 2 months. The car only had 52,000 miles on it and it went bad when it reached 54,000 miles. After fixing that it went bad again after 4 months. I was also told that Hyundai Elantras are known for their engine problems. It would be great if there is an engine recall on this car. I am not trying to sell this car but I was this car to be fixed. Thank you!

Our hyundai elantra 2018 car started with a knocking sound while we were driving and it got worse our of nowhere when we accelerated and suddenly did this throttling sound with a pop. The battery light came on, the engine light came on and suddenly our car engine turned off and we were able to go on the side of the street we were on. Fumes were coming out of the hood and oil began to leak. The car was not able to be turned on to move it. We have towed it to our home, our local mechanic told us it was the engine. It has 135,000 miles on it. We got it from the dealership about 5 years ago and had not had issues until suddenly our engine blew!

When I drive my car shuts off in the middle of driving in traffic I almost got into an accident with my kids in the car The dealership doesn’t know what’s the problem they fixed a code of p0011 can anybody help because it’s a safety hazard with me and my family in the car please help feel like I’m just wasting money

I was at work when my wife contacted me and informed me that the car has started to make a ticking noise (shared car mind you) upon acceleration and start up. This all started on 1/4/2024. Well I checked the oil level and it was a on the line of being on the low side so I changed the oil as I needed to anyways and topped it off. I went to start to the car and ticking again, well I called around as I'm not going to ignore any sort of noise and was able to get a lcoal mechinic to look at it the next day as my local Hyundai dealership didn't have any opening until Saturday (1/6/2024). The next day I'm on my way to drop the car off to see where the sound could be coming from and the car shuts off. There were no warning lights or anything of that matter until the car shut off. I had to pull off into a street off the road. We get the car towed to the mechanic and he gets back to me the next day and states the car had low oil and that is why the engine failed. Hyundai shame on you all for knowingly putting a terrible engine into your products and for also at least not giving us the time by having poor sensors.

The contact owns a 2018 Hyundai Elantra. The contact stated that while a friend was driving the vehicle at various speeds, the vehicle suddenly shut off and would not restart. The vehicle was towed to the local mechanic who was unable to determine the cause of the failure. The vehicle was restarted without any service being performed. The contact stated that the failure occurred intermittently. The cause of the failure was not yet determined. The manufacturer and local dealer were notified of the failure, but no assistance was offered. The failure mileage was 60,000.

Mileage: 60,000

I was driving on the highway early in the morning and my car would not accelerate and slowed down until stopped running. Then the check engine, check oil, and battery light came on after. I tried to restart the car and it would not do anything. I popped the hood to check the oil and there was no oil in the engine. My car was not due for any oil change until another 1000 miles. No notification for low oil. No sounds , no smoke, nothing I had to tow it to my house.

I noticed around 100,000 miles that my car was going through oil when I heard a ticking in the engine. I pulled over and checked and there was no oil on the dipstick. No warning lights or nothing. I just kept adding oil after that and thinking that I will never buy another Hyundai again but never thinking my engine would fail full of oil. In June of 2023 my car lost power just as I got off the freeway. Thankfully it happened just as I got out of rush hour traffic otherwise it could have caused an accident. I had it towed home and the repair shop said my engine failed. I had it towed to a dealer and they confirmed that the engine failed. After many email and phone discussions with the dealership and Hyundai, they said they would cover 50% and then 70% of the repairs. The repair shop in town said this was common in Hyundai's and after checking online I found out that this has been an issue for 6 years before my car was built so Hyundai KNOWINGLY put a defective motor in my car. I have 149,000 miles on it but I still had over a year left to pay on it. just to get it moving I accepted the 70% and 9/27/23 I received an email saying it was done. The same day I received another email saying that they were wrong and it needed another part but should be ready early October. 3 months later I still have no car. I had to use an old truck I have that gets half the mpg. I've been paying insurance and payments on a car I don't have and don't want back. A page on Facebook, Engine Failure Kia/Hyundai describes many people's frustration with the same issue. When most get their car back, the engine fails again. I drive 110 miles a day just for work and its freeway 95% of the drive. If I have to drive in rush hour and my engine fails again, it could be disastrous. I want the dealer to buy my car back with compensation for lost money. I should not be forced to drive something that is a proven hazard on the road. I can mail all pertaining documents if needed. I can't scan them.

WHILE DRIVING, HEARD A LOUD POP THEN SMOKE CAME FROM THE ENGINE. THE ELECTRICAL SYSTEM FLASHED THEN WENT OUT. A PASSER BY COMING FROM THE OPPOSITE DIRECTION STOPPED AND TOLD ME THAT MY CAR WAS ON FIRE. I GOT OUT AND THERE WAS A SMALL FIRE ON THE GROUNG UNDERNEITH MY CAR. THEN OPENED THE HOOD WHERE THERE WAS A SMALL FIRE BEHIND THE ENGINE. ANOTHER TRUCK PASSING BY HAD A FIRE ESTINGUISHER AND PUT THE FIRE OUT. THERE WAS OIL ALL OVER THE ROAD. CALLED A WRECKER SERVICE TO COME AND PICK IT UP. UPON DELIVERY OF MY VEHICLE, THERE WAS OIL ALL OVER THE WRECKER. I'M VERY LUCKY TO HAVE HAD SOMEONE COME BY TO PUT THE FIRE OUT. I COULD OF BEEN IN THE CAR AND BEEN BURNED. THE INSURANCE COMPANY HAS BEEN OUT AND DONE A FULL REPORT ON IT. THERE WERE NO WARNING LIGHT THAT CAME ON DETECTING ANY ISSUES.

Engine completely out of oil. Only owned the car for 9 months. No warning lights no check engine lights just completely stalled on the freeway. Now has a very loud engine knock and needs a new engine

MY 2018 HYUNDAI ELANTRA SHUTS OFF WHILE DRIVING. THE ENGINE AND OIL LIGHTS COME ON AND THE CAR WILL SHUT OFF ANYWHERE WHILE I AM DRIVING AS OF APRIL 02, 2023. I HAD TAKEN MY 2018 HYUNDAI ELANTRA TO THE DEALER TO HAVE THE CRANK SENSOR REPLACED AND THEY COMPLETED THE REPLACEMEMT TODAY, WEDNESDAY, AUGUST 09, 2023. NOW MY 2018 HYUNDAI SHUTS OFF MORE OFTEN THAN BEFORE. I WAS TOLD BY THE HYUNDAI CORPORATION OFFICE TO TAKE MY VEHICLE BACK TO THE DEALER AND INFORM THEM THAT MY 2018 HYUNDAI ELANTRA IS SHUTTING OFF MORE FEQUENTLY THAN BEFORE....AS OF TODAY, WEDNESDAY, AUGUST 09, 2023.

UNKNOWN- intermittently - multiple times a day for the last month the car starts making clicking noises like a card in the spokes of a bicycle. Mechanic could not find the cause. UNKNOWN- two times in 2 weeks- while making a turn my car stalled in the middle of an intersection, all the lights on the dash went on, and wouldn't start up again for a couple minutes. Then car starts and runs fine besides the intermittent clicking

Knocking coming from the engine, OIL in the engine, Oil pressure light came on. Was looked at by two private mechanics and the dealership and was told the engine was faulty and not to drive it. The engine needed to be replaced. Was denied replacement by corporate since it just passed the warranty and was told to go to the BBB if I didn’t like it.

First, the plastic around wheel wells began to come out, then other parts of underneath near the skid area at the front of car begin to drag. Eventually a lot of the plastic pulled away underneath the car taking some of the front bumper. Then the car ran hot and had zero fluid in the radiator even though I regularly have oil changed and fluids topped off. Now the air conditioner throws out hot air when it on. I’ve regularly had oil changed. After only 3500 miles of having oil changed my oil light would come and car stalls when I’m turning. This could get me hit and killed. I bought car from car max and took it back as I have Extended Warranty that I’m paying for. They told me I had to have an appointment nearly a month out. I told them car needed to be seen now, that engine is probably going to go. CarMax refused to see my car and I now have an appointment at the Huyandi dealership . CarMax stated that Hyundai would replace my engine for free. I would like to state that I used car fax and found out car was a rental car and driven in three states. Also according to the vin number the oil in my Hyundai was changed for the first time At 18,000 miles. I still owe three years and I’m not going to have a car because it may blow the engine before I can get it into dealership. I NEVER would have bought the car had I known it was a rental, but CarMax kept telling me it was a one car owner. The car had 36,000 miles on it and I should have known. Yes, it was a one car owner by the Car rental agency and driven by hundreds of people, who didn’t care because it was a rental. Also, the check engine light is on and I can’t get car inspected or renew my tag. I had to replace calipers on both sides of car and I’ve had to have it aligned three times. It also makes a thumping sound on right front tire while I’m driving it. Feels very unsafe. Replaced brakes tires and it still makes noise. There needs to be a way to protect the consumer!!!!

I noticed around 97k miles that car just died as I turned left out of a parking lot at low speed. Thought nothing of it at first maybe I hit the keys with my knee. Then it happened again at 101k and recurred consistantly always within 1000 miles of an oil change at the scheduled interval in the manual. Then at 117k it did it again but when I started the car it developed a loud knock. I got the car home and took it to my mechanic and they said that the engine would need replaced. This is incredibly dangerous as it happens while traveling at speed and you lose control of power steering and acceleration.

I purchased this car as a used car at CarMax in July 2022 and it drove fine for about 10,000 miles, but starting in February 2023, my engine started to misfire. The first misfire happened when I started my car. I was told by my local mechanic that I needed a new engine after a compression test was run. My engine misfired a 2nd time while I was merging on the highway and a third time while I was starting my car. I only have 68,975 original miles on my car. The first 2 misfires illuminated the check engine light and the third misfire illuminated the check engine light, the battery light and oil pressure light, however my mechanic didn't find any codes with my third misfire. My car regularly rough idles and has a delay when I accelerate as well.

ENGINE SHUT DOWN AND INOPERABLE. POSSESSION OF CAR LESS THAN 2 YEARS, DRIVEN TO COLLEGE, WORK, ETC.

The contact owns a 2018 Hyundai Elantra. The contact stated that while operating the vehicle, smoke and an oil leak coming from the engine compartment. The vehicle was towed to the local mechanic who diagnosed that the engine was faulty and needed to be replaced. The vehicle was not yet repaired. The manufacturer and local dealer were notified of the failure, but no assistance was provided. The failure mileage was 93,000.

Mileage: 93,000

I just started my drive and my car seems to have rebooted while I was driving. The whole ordeal only lasted a few seconds. Things I noticed: 1) The steering locked (Guessing the electronic controls were down) 2) A few telltales were triggered and then the instrument cluster went blank 3) A the same time, the infotainment system went blank. Both the instrument cluster and the Infotainment came back after a few seconds 4) The engine revved up a bit at some point This has never happened to me before. I suspect it may be because of a new build software that was flashed to fix a security issue with Hyundai cars but I'm not sure.

Engine internal parts failure causing the car the to become a danger to the occupants of the vehicle and to others on the road the 1.6 litter gdi Engine is known for having Engine problems but little is said about the 2018 tgdi 1.6 litter in the hyundai elantra sport having the same issues. I thought I was getting a safe car for my wife and my children I guess I was wrong. We are second owners of the car we bought it from carmax and we got the max care extended warranty they knew hyundai had engine problems sold us the car without revealing any information about the problems and the when the engine problems accrued they along with another actual hyundai dealer have done everything in their power not to help so I'm stuck paying $16,000 for a car that does not run. I am extremely disappointed in their willingness to accept any responsibility for the faulty engine they $3,600 out of my pocket just for them to check out the engine to see if the would replace it which would not be reimbursed. That is a lot of money just to throw in and hope they'll fix it if not a new motor is $10,000. We don't have $13,600 just laying around. This engine issue has to be addressed I'm sure there are other people having this issue. Thank you for your time

Engine seizes or stalls shutting off the car completely and randomly. This puts myself and passengers and other on the road at serious risk of injury or death due to not being able to maintain speed or control of vehicle. It is available for inspection upon request. It has been an ongoing issue since 2020 and the dealership has “fixed the issue” twice. It is not fixed as it keeps happening. They deny any further issues and claim they cannot replicate the issue. I drove it from the lot again today after they “fixed” it and had it shut off on my way home. There has not been a check engine light that comes on in the past however this time it did making today the first time the check engine light came on. The check engine light came on before the car shut off while driving home from dealership. I put date of occurrence as of today but the first time it happened was back in 2020. It will shut off while at a stop light or even going 45 mph. I am unsure of how many miles were on the car at first occurrence. I think around 20 or many 30k

Engine is defective and using excessive amounts of oil and will eventually fail or seize resulting in catastrophic failure or leaving customer with a lemon that they still own on. Hyundai hasn't issued a recall for this make and model but should have. As a result, been forced to constantly check the oil levels, and oil must be added to the engine more frequently than even the owner’s manuals recommend. MALFUNCTION INDICATOR LAMP (ENGINE LIGHT) suddenly came on at 123K miles. When engine light appeared, customer checked oil level which revealed low/no oil. Engine oil pressure warning light fails to come on dashboard display. Oil change had been scheduled months in advance but not due until about another 770 miles. Customers must suffer through extremely long wait times often 3-4 months later for service appointment at dealership even just for an oil change. The customer also expected to leave vehicle for up to a week or longer just for a diagnosis meanwhile footing the cost to rent a vehicle. Customer having to service vehicle elsewhere for diagnostic only for code to clear temporarily before reappearing. Major issues cannot be addressed timely dealerships, leaving customer with one of two options: drive the car until it fails or foot the bill for a $10,000 engine replacement outside of any Hyundai dealership. Engine should be recalled & replaced under warranty.

I fill up my oil at regular service intervals. When i drive my car after 3500 miles if i turn the engine stalls. This is dangerous due to loss of power. This has happened multiple times.

ENGINE COMPLETLY STALLED WHILE DRIVING, WAS PARKING IN A PARKING GARAGE, AND WAS DRIVING UP ON AN INCLINE TO PARK AND MY CAR JUST STALLED AND ALL WARNING LIGHTS CAME ON. NO WARNING LIGHTS WERE PRESENT PRIOR TO, AND ALL POWER WAS STILL ON. I WAS STUCK IN THE MIDDLE OF THE LANE, BLOCKING CARS IN. I WAS ABLE TO TURN THE CAR OFF AND RESTART IT AND IT STARTED UP WITH NO WARNING LIGHTS AND AS IF NOTHING JUST HAPPENED. I DO NOT FEEL SAFE DRIVING THIS CAR AND WILL BE HAVING IT INSPECTED IMMEDIATELY

Without any warning, the vehicle suddenly shut off while driving in a very busy intersection. It was able to be started two times as we tried to get out of the way of other moving vehicles but it eventually had to be towed. There were no warning lights that appeared on the vehicle to give us any indication something was wrong. It was towed to the dealership and we were told that there was engine damage, the engine needed to be replace and that it would not be covered.

My daughter is in college in Tallahassee. About 4 months ago, she told me that when she presses the accelerator, the car doesn’t go as fast as it should. In July 2022, the car was serviced in Tallahassee at the dealership; however, none of this is reflected on the receipt. In November she came home to Palm Beach County, on her way back, she told me that she was having the same issue when she pressed the accelerator. She made it to Tallahassee and I had her take it to the dealership. The Service Manager called me and said she had gone over the recommended miles for an oil change and this may have caused damage to the engine; however, he decided to change her oil and spark plug which coated about $318. She drove the car for a few days and noticed a loud tapping noise; also, the car rolls in all gears, and the same issue with when pressing the accelerator. Upon taking it back to the dealer, they told me that the engine would have to be replaced at a cost of $9500. The car had sat at the dealer since November 14, 2022 because no one would call back; provide updates after I started questioning the issues with other vehicles like this one based on my research. In addition, I was told the manufacturers warranty did not apply to my daughter’s car because she was the 2nd owner. I had the car towed today, November 30, 2022 to AAMCO. It is available if needed. This issue has put my daughter at risk because Tallahassee is very hilly. The vehicle not getting enough speed to drive up a hill, pass vehicles or possibly be hit from behind puts my daughter and others at risk. The dealership has indicated there is a problem with the engine that will require it to be replaced. The vehicle was inspected by Werner Hyundai in Tallahassee who said there was an issue with the engine. It is now at AAMCO. Outside of my daughter indicating the problem, I am not aware of any other warnings.

The engine suddenly started stalling at stop sign or red lights at random times and the engine immobilizer light came on along with check engine and oil light. This was dangerous when turning left at an intersection. Car would be fine after restarting the car. Other times the ESC malfunction light would show while driving and the engine would not accelerate properly on the highway and the engine would also start jerking at times. Dealer said they could not fix it as this was an intermittent issues and they could not reproduce the issue when given for repair. Dealer and company did not agree to do a complete check and replace sensors, etc.

My Elantra was taken by theft. Rear driver side door broken. Ignition harness torn apart and the car was driven away from my senior living home parking lot on July 23rd at 3 P.M. Police were called but car was taken off the lot before they arrived. I received call from police on July 27th that the car was in an impound lot in St. Paul. Drivers side front tire blown out, wheel severly damaged. Some body scratched in left rear. Front passenger seat badly stained. Other damage unknown. Vehicle been at Walser Hyundai since about August 1st. Shop waiting for parts for repairs.

The contact owns a 2018 Hyundai Elantra. The contact stated that while her son was driving at an undisclosed speed, there was a loud sound coming from underneath the vehicle with the check engine warning light illuminated. Additionally, there was smoke coming from the front end of the vehicle. Another driver alerted her son that there was a flash of flame coming from underneath the vehicle. The vehicle was towed to the dealer where it was determined that the engine needed to be replaced. The vehicle was not repaired and remained at the dealer. The manufacturer was made aware of the failure and a case was opened. The manufacturer informed her that the vehicle was out of warranty and offered to cover 60% of the repair cost. The failure mileage was approximately 70,000.

Mileage: 70,000

The car has a security vulnerability where the car is able to start without the key being present. Also, the engine will shutter randomly (car will shake) when in idle. This happens especially the first few minutes from a cold start.

My car will shut off as I’m driving it. I was going thru a busy intersection and my car turned off, I was in my car with my 3 babies traffic backed up and almost got slammed into. I had to get out and push my car to the side of the road. The check engine light started flashing then the whole dashboard started flicking

While driving lost acceleration, car stalled multiple times. No dash light on at all when this happens. Having to add oil to my engine between oil changes.

The contact owns a 2018 Hyundai Elantra. The contact stated while driving 35 MPH, she depressed the accelerator pedal and the vehicle began to jerk and shake from the front end. The vehicle also hesitated prior to responding to the accelerator pedal being depressed. The contact stated no warning light was illuminated. The failure had become a recurring failure. The contact had taken the vehicle to a local dealer however, the vehicle was not diagnosed or repaired. The manufacturer had been informed of the failure. The failure mileage was approximately 38,000.

Mileage: 38,000

While driving, the acceleration stopped working and loud clanging noises were heard in the engine. There were no warning lights, nothing. I was driving on a busy road and the lack of acceleration created a major safety hazard for me and the vehicles around me. I eventually pulled over and restarted the car. It happened three more times on the way home. I got the car to my local mechanic and he said that it was the engine and it needed to be replaced. He saw this many times before on this model and told me to bring it to the dealer. I had the car towed to the Hyundai dealer/service center in Milford, Connecticut. I am waiting for them to look at it. I know that this has happened to many others with a 2018 Elantra and I am very upset that the car failed.

Engine stalls while driving. No warning, intermitted full shut down of the engine. Can happen multiple times in a row, only making it a few hundred feet before stalling again. The only remedy is to put the car in park and start the engine again, however, that is not always easy to do when on the road, and the car can only drift and brake. It is not safe when the car stalls, especially in traffic -- can be dangerous to myself and others on the road if I am unable to pull the car over or get it to start up again on the interstate. I have been to a mechanic, and 2 dealerships who claim they cannot replicate the problem, and even when it stalled in the parking lot when I was leaving, there were no error codes on the computer. This being said, without a code or a proper diagnosis, I am at a standstill because "nothing can be done or authorized' by Hyundai without a code. I have been suggested by both dealerships to try and run it and 'kill the engine' because it is still under warranty for another 15,000 miles--but this puts myself and other drivers at risk because the car is unsafe to drive. There is a code from July 16, 2020, a little less than 2 months before I purchased the car about an engine light, this has yet to be addressed. This problem appeared out of nowhere one day while driving on the interstate and has been an issue ever since.

The contact owns a 2018 Hyundai Elantra. The contact stated while driving approximately 35 MPH, the vehicle stalled and lost motive power. The check engine warning light illuminated. The vehicle was towed to the dealer. The vehicle was not diagnosed; however, the contact was informed that the engine needed to be replaced. The vehicle was not repaired. The contact related the failure to NHTSA Campaign Number: 21V301000 (Engine). The manufacturer was notified of the failure. The approximate failure mileage was 106,000.

Mileage: 106,000

My husband was driving the car when all of a sudden it stalled during morning rush hour traffic. As traffic zipped by us he quickly put the car in neutral and started the car. When it turned back on the car made a loud knocking noise. He proceeded to drive back home where it stalled one more time. When he was getting close to the house the knocking noise got louder. He then called our local Hyundai dealership and they stated that they would not inspect the car for well over a week. We then had a mechanic come over the house to take a look at it. The mechanic stated that we didn’t have any oil left in the engine. Even though we had an oil change three months, the engine had burned through all of the oil. We bought oil to fill the engine but chose not to drive the car anymore out of fear for our safety and of messing up the engine any further. The car has not been inspected yet by the manufacturer, but we are speaking to Hyundai Consumer Affairs about it. Also, before the incident and at the time of, there was no lights or warnings for the engine or that it was missing oil.

UNKNOWN - for the past several months, since my car hit the 70,000 mileage mark, my check engine light has come on while experiencing hard idling, delayed acceleration/power while driving - particularly on gradual inclines and hilly roads. I would suspect it has something to do with the power or fuel system. I have changed oil twice and had a diagnostic test done and mechanic is unable to pinpoint issue since it is not consistent.

Multiple events of engine shutoff while driving. This results in loss of power braking, power steering and any acceleration. This occurs both at highway and non-highway speeds. This is obviously a safety concern, as, until the engine is restarted, there is difficulty in safely manuevering the vehicle. The engine may or may not be immediately able to restart. This occurs with the vehicle in gear during normal driving conditions (IE, driving at a steady speed on flat road) This is accompanied by multiple CEL faults relating to CCV timing, engine misfire, etc. This was a known issue in prior engine revision (Theta 2.0L), and appears to be subject to a recall of the same engine (Nu 2.0L) in other models. This vehicle was taken to the local dealer and confirmed to need an engine replacement with a similar failure mechanism as the Theta 2.0L (failed lubrication of pistons resulting in premature wear leading to early failure resulting in misfire/"piston slap")

I just purchased this car on may 10 2022 after only having it a week engine light came on.startes to loose power and shake really bad. Took to shop replaced spark plugs and some other .think that was just a week ago .now while driving to day car just cuts of now don't wants to start.no waring lights just died .wondering do I have a lemon.

At slow speeds car just shuts off engine. Starts back up but does it constantly. Also the engine lifters are starting to make noises like a clacking someone said it was a defective motor.

I've had several issues over the years with this vehicle but nothing too major but more so a nuisance. Such as the car hesitating when accelerating, light bulbs constantly burning out on the vehicle within less than a year of being replaced by myself , etc. It is now April 2022 and vehicle problems begin arising, I heard a weird noise coming from the engine (after much personal research learned this is a knocking sound). Which also happens to be the same issue from the prior year models. One day while out running errands the car just completely dies and goes into limp mode while I was turning onto a busy street (very dangerous). I drove it a very short distance back & forth to work a couple of times because thats as far as I felt going safety wise. The engine jerked forward one day but still continued to run. Then one day on my way home from work when I began slowing down to turn into a driveway. The car completely died again. It went into limp mode enough for me to creep and barely park it where I ended up having to get out & push the vehicle. It doesn't turn over or start at all now. The car gave absolutely no warnings no codes for me to turn to regarding what was going on etc. Hyundai says in order for it to be covered under the warranty that I have to provide them with information. Which I have no problem doing. However based on the research that I've done from other Hyundai Elantra owners others have had similar issues. My Car is barely 4 years old & only has about 65,000 miles on it. I went with Hyundai's because I wanted something that would be safe and reliable especially because I had a child coming into the world at any moment. I ended up going with this vehicle which isn't even 5 years old & it has already become a lemon. Hyundai currently has the vehicle as I try to figure out what to do with it. Since I no longer feel safe driving it. There are no warning lamps etc that came on.

Engine would randomly idle mild to very rough when started and would sometimes correct and sometimes not correct while driving. This would turn on the check engine light for a misfire on cylinder 4. All ignition coils were replaced, and same code would happen. Hyundai was aware of this being a widespread issue and did a software update (Tech Bulletin 90C042R1). The problem continued, but seemed the check engine light would not come on as soon as before the software upgrade. Took back to dealership and they said the ignition coils would need to be Hyundai brand, change cylinder 4 to OEM and still having the issue. Engine also burns about 1 quart of oil every 7000 miles and often has a rough idle, with very rough idle periodically. I feel this would put myself and others on the road in danger if the engine were to fail while driving due to the ongoing damage rough idling appears to be causing to the engine.

While driving the vehicle this past January, I experienced a brief “clunking” noise in the engine, and the car stalled. The check engine came on briefly and then disappeared. The code identified was a “faulty crankshaft” code. I made an appointment with the dealership to take it in to be inspected, but later that day my son was driving to pick me up from work and the vehicle literally died in the middle of an intersection. No warning, all lights came on in the vehicle, the electrical system terminated, and the vehicle died. I had to have it towed to the nearest garage, which was a Pep Boys, and they diagnosed the problem as an alternator and battery, serpentine also. So. 1300 dollars worth of work later…. Turns out the car has an engine issue.

MY 2018 ELENTRA VALUE EDITION STARTED KNOCKING IN AUGUST OF 2018. I CALLED THE DEALERSHIP IN CHILLICOTHE OH AND THEY TOLD ME IT WAS FINE TO DRIVE AND TO BRING IT IN THE FOLLOWING MONDAY. THEY SAID I SHOULD PLAN TO WAIT WHILE THEY LOOKED AT IT AND THAT I WOULD BE DRIVING IT HOME THAT DAY.. I DROVE ABOUT 20 MILES AND THE ENGINE MADE A LOUD NOISE AND DIED. THEY NEVER TOLD ME WHAT CAUSED THE FAILURE BUT THERE WAS OIL AND CHUNKS OF ALUMINUM ALL OVER THE ROAD. THEY REPLACED THE ENGINE UNDER THE WARRANTY. THE CAR HAD 33,000 MILES AT THAT TIME. THEN ON DECEMBER 23 OF 2020 MY ENGINE STARTED MAKING THE SAME EXACT NOISE. THE CAR IS NOW OUT OF WARRANTY WITH 144,000 MILES ON IT. I REMOVED THE OIL PAN TO FIND THE PROBLEM. IT WAS THE NUMBER 3 CYLINDER. THE CONNECTING ROD BEARING WAS BAD. I CLEANED THE JOURNAL ON THE CRANKSHAFT AND MEASURED IT WITH PLASTIGAUGE. IT WAS 0.001" OVER THE TOLERANCE. I INSTALLED NEW BEARING ON ALL FOUR RODS IN HOPES THAT 0.001" OUT OF TOLERANCE WOULDN'T BE TO MUCH. EVERY BEARING ON THE ROD SIDE WAS WORN OUT AND THE COATING GONE. THE BEARINGS ON THE BOTTOM "CAP" SIDE WERE IN DECENT SHAPE EXCEPT FOR THE NUMBER 3 CYLINDER WHICH WAS DESTROYED. AFTER THE ENGINE HAD STARTED AND I HAD DROVE FOR AROUND 5 MILES IT STARTED KNOCKING AGAIN. THE JOURNAL ON THE CRANKSHAFT IS TO WORN FOR THE BEARING TO WORK. I HAVE AN ENGINE ORDERED AND I AM REPLACING IT MYSELF. I HAVE SEVERAL YEARS OF SCHOOLING IN AUTO MECHANICS AND HAVE GROWN UP IN A GARAGE, I UNDERSTAND THE IMPORTANCE OF MAINTENANCE AND NEVER MISSED ANY ON MY CAR. IT HAD EVERY OIL CHANGE WITH SYNTHETIC OIL, OIL FILTER CHANGED EVERY TIME, FLUID LEVELS WERE CHECKED ON A REGULAR BASIS AS WAS THE AIR FILTER. THE CAR ISN'T DRIVEN HARD, THERE IS NO REASON FOR THE ISSUES I'VE HAD OTHER THEN DEFECTIVE PARTS OR DESIGN OF THE ENGINE IN THIS CAR.

IN NOVEMBER 2018, I TURNED ON MY CAR, AND THE ENTIRE VEHICLE SHOOK VIOLENTLY. I TURNED IT BACK OFF, THEN ON. IT SHOOK AGAIN, AND THE CHECK ENGINE LINE WAS ON. I CALLED THE DEALERSHIP, AND THEY SAID SINCE THE LIGHT WASN'T FLASHING, I COULD DRIVE IT OVER. TURNED IT ON, NO ISSUES, DROVE OVER. THEY READ THE CODE AND REPLACED THE IGNITION COIL. MILEAGE WAS 12,884. THIS MORNING (MAY 2), THE CAR TRIED TO TURN ON, BUT COULDN'T (LIKE A DYING BATTERY). OIL, ENGINE, AND BATTERY LIGHTS ALL CAME ON. WAITED A FEW MINUTES, TRIED AGAIN, SAME ISSUE. THE THIRD TIME, IT FINALLY STARTED, BUT SHOOK VIOLENTLY FOR A COUPLE SECONDS. NO LIGHTS ILLUMINATED. CALLED THE DEALER, THEY SAID TO DRIVE IT OVER. THEY ARE UNABLE TO REPLICATE THE PROBLEM, AND SAID IT CAN'T POSSIBLY BE THE IGNITION COIL, AND CAN'T DO ANYTHING FOR ME. THE CAR CURRENTLY HAS JUST OVER 15,000 MILES. ALL MAINTENANCE HAS BEEN DONE BY THE DEALERSHIP PER THE SCHEDULE. I USED THE CAR THE EVENING OF MAY 1 WITH NO ISSUES, AS WELL AS FOR A 45 MINUTE DRIVE ON APRIL 29, SO, I DON'T BELIEVE IT'S THE BATTERY, EITHER. THIS IS A KNOWN ISSUE WITH THIS MAKE/MODEL OF CAR.

WHEN ACCELERATING WITH MODERATE TO HEAVY THROTTLE INPUT, THE ENGINE EMITS EXCESSIVE PINGING AND RATTLES NOISES. IT SOUNDS LIKE "SPARK KNOCK". NO MATTER WHAT BRAND OF FUEL OR OCTANE I RUN THE CAR ON, THE ENGINE MAKES THESE PINGING AND RATTLING NOISES. I'VE BROUGHT THE CAR TO THE DEALERSHIP SERVICE DEPT. TWICE SO FAR TO ADDRESS THIS CONCERN. I WAS INFORMED THE FIRST TIME THAT THEY HEAR THE NOISE, BUT CANNOT DIAGNOSE IT BECAUSE THE CHECK ENGINE LIGHT ISN'T ILLUMINATED. ON THE SECOND VISIT, THEY TOLD ME IT IS A NORMAL NOISE FOR THE CAR. HAVING OWNED A HANDFUL OF VEHICLES OVER THE YEARS, THIS NOISE IS INDICATIVE OF SPARK KNOCK. IF THE PROBLEM IS INDEED EXCESSIVE SPARK KNOCK, THIS CAN LEAD TO CATASTROPHIC ENGINE FAILURE, CAUSING SUDDEN LOSS OF ALL POWER. AFTER RESEARCHING THE ISSUE ONLINE AND SPEAKING WITH OTHER OWNERS, IT IS APPARENT TO ME THAT IT IS A FAIRLY COMMON PROBLEM WITH THE 2018 HYUNDAI ELANTRA SEDAN. I WOULD LIKE HYUNDAI TO INVESTIGATE THIS ISSUE AND COME UP WITH A FIX. THIS PROBLEM HAS EXISTED SINCE BRAND-NEW OFF THE DEALER LOT. THE CAR CURRENTLY HAS APPROXIMATELY 4,000 MILES.
