general problems of the 2018 Hyundai Elantra - part 2

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!.

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.

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!.

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.

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.

See attached document for complaint.

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.

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.

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.

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

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.

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.

The contact owns a 2018 Hyundai Elantra. The contact stated that the seat belt was inoperable. The contact stated that the air bag was falling out of the air bag enclosure. The vehicle failed to start immediately but was started after several attempts. The air bag and seat belt warning lights were illuminated. The contact stated that the battery terminal posts were inoperable. The vehicle was taken to an independent mechanic, who tightened the battery post. The local dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was not contacted. The failure mileage was approximately 46,000.

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.

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 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.

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.

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.

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.

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.

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 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.

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.

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 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.

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.

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.

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 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.

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 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.

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.

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.

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.
