2018 Hyundai Elantra

This vehicle lacks an engine immobilizer, a defect that has made 2011-2022 Hyundai and Kia vehicles unusually susceptible to theft via a method widely publicized on social media as the "Kia Challenge." My vehicle was stolen using this method, driven approximately 30-40 miles, and abandoned. It was found stripped of parts, including the catalytic converter. This defect is already the subject of a nationwide class-action settlement (hyundaitheftsettlement.com) and a multistate Attorney General settlement. I am filing this report to ensure my vehicle/incident is included in NHTSA's records on this ongoing safety issue.

The engine in my 2018 Hyundai Elantra suffered a sudden internal failure at 118,444 miles. The vehicle began knocking, losing power, and running roughly. A dealership inspection confirmed heavy scoring on cylinders 1, 3, and 4, oil intrusion into the cylinders, and piston top slapping. The engine is not repairable and requires full replacement. This failure matches the known defect pattern of Hyundai’s Nu 2.0L MPI engine, which has widespread issues with piston ring wear, oil consumption, cylinder scoring, and internal mechanical failure. The failure occurred without warning/messages and created a safety hazard due to loss of power while driving. My VIN is not included in any recall, but the defect is identical to other Hyundai engine failures that have resulted in recalls and investigations. I am reporting this because the engine failure appears to be part of a larger safety‑related defect affecting this engine family.

Alarming rate of oil consumption causes sudden loss of power / acceleration which definitely increases probably of causing an accident. Local repair shop confirmed extremely low oil level with no evidence of where oil went shortly after oil change and annual safety inspection. All the dashboard warning lights came on when it happened but low oil warning light came on prior to event. No warning whatsoever, just sudden loss of power and completely lit up dashboard.

Engine has consumed an alarming rate of oil for years. I brought to a mechanic and they performed a $2,600 repair on engine. It ran fine for while and got much worse with oil consumption to the point that I needing to add oil monthly. It has been difficult to keep up on keeping enough oil in car and engine has now sustained damaged. There is no ticking or noise, but there is a loss of power and sometimes, the engine runs rough. I continue to drive it and add oil. But I have researched this is an apparent problem with the elantra.

The vehicle is experiencing premature paint failure and delamination on factory-painted body panels with Quartz White Pearl (W8) paint. Paint is peeling, chipping, and separating from the underlying surface without collision damage, abnormal wear, or neglect. The issue appears consistent with widely reported Hyundai white paint adhesion defects affecting similar vehicles and paint codes. The condition developed gradually and continues to spread to additional areas of the vehicle. The affected paint failure exposes underlying surfaces and may reduce long-term corrosion protection of the body panels. No warning lights or messages appeared prior to the issue. The vehicle remains operational, but the paint defect appears to involve loss of adhesion of the factory-applied paint system rather than normal cosmetic wear or isolated rock chips. The issue is available for inspection upon request. The manufacturer has issued warranty extensions and programs related to similar white paint delamination conditions on Hyundai vehicles, but this vehicle was reportedly excluded despite having the affected paint code and similar failure pattern.

I am filing a safety complaint regarding a complete engine failure on my Hyundai vehicle. My vehicle experienced sudden engine failure and is now completely inoperable. There were no prior warning lights that indicated an imminent failure (or: include warning details if you had them). The vehicle shut down and cannot be restarted or driven. There are no open recalls associated with my VIN; however, I am reporting this because the failure appears to be sudden and severe, and I am concerned it may indicate a potential manufacturing defect or broader engine issue. The vehicle is still under financial obligation, and the engine failure has rendered it unusable. I am requesting that this incident be documented for safety tracking and investigation purposes.

The vehicle is experiencing engine-related excessive oil consumption, which has led to failure of the catalytic converter and emissions system. The root issue appears to be an internal engine defect causing oil to burn during operation. Yes, the vehicle is available for inspection upon request, including the engine and catalytic converter components. The excessive oil consumption creates a risk of engine damage or sudden engine failure while driving, which could lead to loss of power in traffic. Additionally, a failing catalytic converter can cause reduced engine performance, stalling, or overheating, increasing the risk of unsafe driving conditions, especially on highways or in heavy traffic. Yes, the issue was previously reported to a dealership, including concerns about excessive oil consumption. The problem has continued and worsened over time, now resulting in a check engine light and catalytic converter-related fault codes, confirming the ongoing condition. The vehicle has been inspected by a dealership service department in the past regarding oil consumption concerns. At this time, it has not been inspected by police or insurance representatives. Further inspection by the manufacturer or authorized dealership can be conducted upon request. Yes, symptoms began with excessive oil loss requiring frequent top-offs, followed by the appearance of a check engine light. The issue was first reported approximately one year ago and has progressively worsened, ultimately resulting in catalytic converter-related fault codes and continued oil consumption.

I am writing to formally report a safety concern regarding my 2018 Hyundai Elantra. The vehicle has experienced a failure of the heater hose/pipe, which appears to be made of plastic and connected to a metal component. This failure has resulted in a coolant leak, creating a serious risk of engine overheating. This issue is not only inconvenient but also dangerous. A sudden loss of coolant while driving can cause the engine to overheat without warning, potentially leading to engine failure, loss of vehicle control, or leaving the driver stranded in unsafe conditions. This is especially concerning while driving on busy roads or highways. Based on my experience and discussions with repair professionals, this appears to be a known issue with this model, as the part is not widely available outside of Hyundai/Kia and may indicate a design flaw. A critical cooling system component should not fail prematurely under normal driving conditions. Given the safety risks associated with this defect, I believe this issue warrants further investigation and consideration for a recall or extended warranty coverage. Consumers should not be responsible for costly repairs caused by a potentially defective design. I respectfully request that Hyundai review this issue and provide assistance with the repair, as well as take appropriate action to ensure the safety and reliability of affected vehicles. Sincerely, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I've contacted Hyundai to try and do a recall repair on my Hyundai Elantra GT 2018 both through a local dealership (Planet Hyundai in Golden, CO) and Hyundai corporate. The engine is stalling and knocking very bad to the point where it's no longer drivable. It's burning oil non-stop and I am constantly adding oil to it. I'm getting pushback from Hyundai saying I never fixed the recall when I was actually not notified to begin with. I'm the 2nd owner of the car so if I was never notified, how can I be responsible for something I was never told about? Now they are saying this little sensor was supposed to help let you know there's a problem with the engine (sounds like a check engine light?). Hyundai has known about their engines being faulty for quite some time. I need this vehicle to get to and from my job as well as taking my grandson to multiple doctor's appointments each week because he has a disability (he's only [XXX] old). They need to take responsibility for this. Is there anything the NHTSA can do? INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I purchased the car on April 7th, 2022 with roughly 115k miles on it and got a blinking CEL shortly after. The engine was listed as a recall and was swapped with 115,610 miles on it directly after the swap. During this, the Hyundai dealership representative called Hyundai's engineer department twice, trying to get this taken care of by Hyundai/paid for by them and they denied it twice, causing me to have to pay half of what the company I got the car from covered. I was told it was denied due to being the 2nd owner and for high mileage/being out of warranty because of this mileage. I submitted all repair invoices and proof of payment through the Hyundai Campaign Reimbursement Portal, got ignored for about 3 months, then when I followed up, I was denied for the same reason, approximately around September 30th, 2025. The settlement terms for these engines typically cover all subsequent owners and do not have a mileage cap for the lifetime warranty, yet I was still illegally denied. As seen, That you have already exhausted Hyundai’s internal rebuttal process without success. I would appreciate any and all help in receiving the money paid rightfully given to me due to Hyundai's non compliance on this matter, thank you very much.

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.

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.

Car was being driven home when car started shaking heavily and check engine light started flashing. Car had been needing 1qt of oil every 600-800 miles, depending on drive (highway would go longer). Pulled off to the side and plugged in code reader - found that cylinder 3 misfired and catalyst system below threshold. Was able to get the car home. Towed it to Hyundai dealership the following week once they were available and they found a bad cylinder head and leaking cylinder. Assumption is the amount of oil it was using ended up backing up carbon buildup. Car has less than 100,000 miles on it and even with maintenance it needs a new engine.

I have been having transmission issues with my car since before July 2024. The transmission would stutter or not engage when I put my foot on the accelerator. The transmission failed in November 2024 and was eventually replaced by Hyundai in May 2025. I noticed stuttering the first day of having my car back but was told there was nothing wrong with it. Today, Sept.11, I was making a left turn on a busy two lane road. I had enough distance between the oncoming truck to make the turn. When I put my foot on the accelerator, my car rolls into the road but clutch is not engaging. As the truck is now fast approaching my car that's basically sitting in the road the clutch engages. Since my foot had been on the accelerator the whole time, I was probably at like 3000rpm so we lunged forward slamming our heads into the seat. Every time I have taken this car to Hyundai complaining about issues with the transmission they say it's perfectly fine. Since their certified technicians say it's perfectly fine, then I am only left to assume that there is an inherent flaw in the transmission that is allowing events like this to occur and based on my experience have the potential to result in a crash.

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.

In mid-2024, the vehicle experienced a flashing check engine light. I brought it to Murfreesboro Hyundai (TN), where they confirmed the oil was low and started an oil consumption test. A bearing clearance test (BCT) was also performed and passed. After back-and-forth over several weeks, I was told the oil consumption was within spec, but the dealership stated Hyundai would cover all necessary repairs, including a combustion chamber cleaning, under warranty. I was told this work was completed and the vehicle was returned to me. In July 2025, the exact same flashing CEL returned. I brought the car back to the same dealership, where they again found the oil was 2.5 quarts low. However, this time they claimed no previous combustion cleaning or repairs had been done, and that I would now need to pay over $1,100 out of pocket for the same cleaning that was supposedly already performed — and which they had told me would be covered under warranty. This indicates that the dealership misrepresented completed service work, failed to address a recurring defect, and is now trying to shift the financial burden to me. Hyundai’s claim that oil consumption is not “high enough” to warrant coverage is concerning, especially when the condition continues to damage the engine and cause driveability issues. This appears to be part of a broader known defect affecting Hyundai 2.0L engines. I am requesting that NHTSA investigate Hyundai’s handling of oil consumption, engine misfire, and warranty practices related to the 2018 Elantra GT and similar models.

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.

It uses a lot of oil with no visible leak or reason. I put new oil in all the time. All the time! For two years since buying it used. Warning light does not come on till it's out. Car is hot, of course, and stops running in the middle of the road. I see there is a recall on some elantras for oil piston seals but not this car. Seems it should be.

I am writing to report an issue with a paint recall repair performed on my Hyundai vehicle. The vehicle was repaired in 2023 at Sheehy Hyundai of Waldorf. However, the paint has started peeling within one to two years of the repair, which indicates that the issue was not properly resolved. I spoke with Hyundai corporate office which offered no solutions and deferred me to the dealership whom performed the repainting. After speaking with the dealership I was told that is just what happens with this color vehicle and that a ticket of some sort was submitted and denied by corporate to fix the issue. I am seeking assistance from the NHTSA to address this matter and ensure that the recall repair is appropriately handled.

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

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.
