Engine And Engine Cooling Problems of Hyundai Elantra - part 1

Vehicle routinely sputters and stalls at slow speeds. This happens once or twice during most times I use the car. This has happened in intersections and on highways at stop and go traffic. The car is not safe to drive. I haves brought the vehicle into the dealer at least three times for this and they have replaced a different valve (don't know what it was) on two of the occasions but the problem continues. I have an upcoming appointment with my authorized Hyundai dealer (the vehicle is still under warranty) and hope I have better luck next time. But a vehicle that stalls on every trip is not safety.

I am writing to formally file a safety complaint regarding my 2020 Hyundai Elantra. I recently learned that Hyundai issued a recall related to a defect that poses a risk of engine fires in certain vehicles. However, my vehicle, which has exhibited the same dangerous symptoms, was not included in this recall campaign. Specifically, my vehicle has experienced a critical error relating to a defect included in NHTSA recall #21v-301, which I understand is directly related to the safety defect identified in Hyundai’s recall. Despite this, I have not received a recall notice, and Hyundai has declined to provide repair coverage under the recall. This raises serious concerns for my safety, the safety of my passengers, and the public. A defect that can cause an engine fire should not be limited to specific VIN ranges if the underlying issue is present in additional vehicles like mine. I respectfully request that NHTSA investigate this matter and ensure Hyundai expands the recall to include affected vehicles such as mine. If Hyundai continues to exclude vehicles with the same defect, I believe this could warrant further legal and consumer protection actions, including potential class action litigation. Please find my vehicle information below: 2020 Hyundai Elantra VIN: 5npd74lf1lh538038 mileage: 51,000 thank you for your time and attention to this urgent safety concern. I look forward to your response and am willing to provide additional documentation, repair invoices, or photographs as needed. Sincerely, alexis beliveau.

In or about December/2022, I had made numerous attempts to fix my vehicle's engine. It kept stalling on the roadway and finally Hyundai agreed the motor was the problem and they ended up installing a new motor. The vehicle was then out not warranty and they said they were not responsible for the vehicle any longer. The vehicle's check engine light kept coming on and off at times. I did minor work to the vehicle and kept up with maintenance. Now my vehicle's motor is blown again without notice. It stalls on the highway and leaves me stranded. I believe that this type of vehicles were flawed from the beginning. I really convinced these vehicles should be recalled and taken off the highways since, in my opinion, they are not safe to be on the road.

The component that failed was the pistons in my engine on my 2019 Hyundai Elantra se which I see is on recall. I understand that my VIN may have been missed or looked over during the recalling systems decision making. I was on my way to work when my engine just shut off in the middle of traffic! since that happened my anxiety levels has been extremely high! I took my car to the dealership and they confirmed that it was my pistons and to keep checking the recall website because they have seen something like this before. Before the engine cut off there was abosulutly no warning! date of incident [xxx] information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

My 2015 Hyundai Elantra fits the 'window' of Elantras where the engine transmission slips gears without notice. Hyundai dealers have been replacing transmissions at no cost, if the car is still under 100,000 miles, as part of a class action settlement. As the second owner, I have no warranty rights to get Hyundai to fix my car at no cost. This is despite the Hyundai dealer just today (Aug 20, 2025) here in las vegas was ready to replace my transmission at no cost until they found out I am the second owner. The car is still unsafe. The need is still relevant. The dealer was willing at first. Now I am faced with an unsafe vehicle forced to possibly pass in excess of $4,000 to fix an issue that has been know and litigated.

After the recall at Hyundai, my car wouldn't run and there were many lights on the dashboard. It was later checked and the instability light problem persisted. They fixed on the same time, and say something problem with the update. They later informed me that I have a problem with the brake switch, and the brake lights don't work because of it. I replaced and doesn’t work, I went back to the store and they want me to pay a fee to have it analyzed again. Even though before the recall, the lights and the car were working perfectly.

The contact owns a 2019 Hyundai Elantra. While the contact’s daughter was driving at an undisclosed speed, the vehicle stalled. During the failure, the check engine and oil warning lights were illuminated. The vehicle was later towed to an independent mechanic and was diagnosed and determined that the engine had failed and needed to be replaced. The vehicle was not yet repaired. The contact was informed that the VIN was not included in NHTSA campaign number: 21v301000 (engine). The contact stated that the vehicle had experienced the same failure listed in the recall. The failure mileage was 130,000.

The car turn off in the middle of the road and it ain’t wanna turn back on and I had cars behind me and almost hit the back of my car my emergency light were on too and I was in the city I had to get it towed.

On August 9, 2025, my 2013 Hyundai Elantra suffered catastrophic engine failure while driving. The engine seized, creating immediate danger on the road. This vehicle is under NHTSA recall 23v651000 (Hyundai recall 251), which warns of fire/engine compartment risks both while parked and driving. Hyundai denied my claim, citing a vendor report that found “no thermal damage” to the abs wiring. However, the dealer’s inspection confirmed internal engine failure with thermal damage, and I directly witnessed flames. The recall does not require abs wiring itself to burn , it covers the broader safety hazard of fire and failure, which is exactly what occurred. In addition, Hyundai tried to shift blame onto owner maintenance. Their own recall language acknowledges failures occur due to the defect, not neglect. Furthermore, the handling by Hyundai’s case managers was unacceptable: my case was transferred without notice, calls were ignored, and I was left without clear instructions or remedy while my vehicle was disabled. I have attached the denial letter, the dealer report, the recall notice, and proof of maintenance. I request NHTSA review Hyundai’s mishandling of this recall obligation and require them to provide remedy and compensation.

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

My 2013 Hyundai Elantra with the 1. 8l nu engine suffered catastrophic engine failure. A mechanic found metal shavings in the oil and diagnosed a failed connecting rod bearing. The Hyundai dealership quoted $10,000 for a new engine and refused warranty coverage because I am over 120,000 miles, even though this is a well-documented defect. Hyundai issued TSB 22-em-007h covering rod bearing wear in this engine, and there have been class actions and warranty extensions for similar failures. This failure creates a safety hazard, as the engine can seize or stall suddenly while driving, increasing risk of an accident. I request NHTSA investigate this known defect in the 1. 8l nu engine, as it poses a safety risk to myself and others.

While driving down the road, the car lost complete power. No warning lights came on until after the car had lost power. Car struggled to start back up. I put flashers on in hopes that others would notice my disabled vehicle in the middle of the road, while it was also pouring down the rain. The vehicle was towed to my local dealership where it was confirmed that I would need a new engine. The engine had a high oil consumption issue that caused it to stale while driving. The dealership informed me either there was a rod bearing issue or a piston slap in the engine. They recommended to park the car until fixed.

When you accelerate & let off the gas pedal, the vehicle still accelerated for 2 seconds after you release the gas pedal. It is like there is a delay with drive by wire signal. This situation can cause rear end collisions & hard panic braking. Please recall this situation to prevent higher insurance cost & increased accidents!.

I have taken my car in twice due to my car braking when there is not a vehicle and or object in front of me but there are vehicles right behind me that have to brake but crain denies that there are any issues. My engine light came on a couple of weeks ago and I took it to auto zone to have a diagnostic test done. The report states that it has something wrong with the transmission/transmission line and or fluid. When I looked it up online it stated that there are recalls on engine pistons that could cause the diagnostic test to read that it's the transmission. My car is a 2020 Hyundai Elantra value edition but according to your website, there are no recalls!?.

I purchased my 2019 Hyundai Elantra from a third-party dealer (mike carlson motor company in haltom city, TX) on may 30, 2024. I have kept the oil changed on a regular basis since I purchased it. At the time I bought the vehicle, I purchased an extended service warranty that was through assurant/first extended service corporation. July 16, 2025, while out of state (over 640 miles away from where I purchased the vehicle) my vehicle started making a rattling sound from the engine. The mileage on my vehicle was 85,320. I called the warranty company and opened a claim. I was told since I was not in the dfw area and more than 40 miles from the selling dealer or any sister properties, I could take it to any shop that will accept warranty work. July 18, 2025, the vehicle was finally picked up by a towing company and taken to the mechanic. An estimate was created on 07/23/25, stating test system oil is full, has code p0304 (which I looked up and is a misfire in cylinder 4), engine knocking from rod and/or piston, will need engine. Claim was sent to warranty company 07/31/25 and was finally denied today 08/08/25. First, they said lack of maintenance however, they had copies of all receipts. Then they said denied because covered under Hyundai powertrain warranty. However, after speaking with Hyundai customer care, it wasn't sold pre-owned certified. Had to send proof to warranty company showing no factory warranty (sent signed selectcertified form signed date of purchase). Now it was denied again stating open recall on vehicle would have to contact Hyundai. The nearest Hyundai dealership is over 1 hour or more away. I'm hoping tomorrow when I reach out to Hyundai they can shed some light on the situation. I've been stranded in illinois (I live in texas) since 07/16/25 and have made no head way to get the vehicle back on the road.

When driving at low speeds(20mph and under) vehicle stalls. It appears to happen at random. It makes driving pretty dangerous for other vehicles that would not be able to tell the vehicle has stalled and hit me at low speeds. All electrics stay on, there is no check engine light. The problem first appeared after ignition lock was broken, even before replaced it started stalls at low speeds, seems to possibly happen more after engine is warmed up.

Spun bearing in engine. All service on vehicle up to date.

Car began to make clicking noise which turned into a louder “dying” sound. Car completely stopped, and had to get towed. I was told the engine failed due to parts from the recall.

This seems to be a very common and serious issue with Hyundai vehicles. 2013 Hyundai elanta, believed to be a frequent crankshaft position sensor issue. When driving the car, they vehicle will feel that it is losing power. When coming to a stop the engine will idle so low that it feels like it will stall or it does stall. The tachometer registered zero rpm's, even when accellearting. Attempting to accelerate up any incline and the car can not provide enough power. Sometimes the car will crank up, other times it will require time to restart. The car has stalled and low power idling multiple times, but it did happen in the middle of a 4 way intersection twice, and when the issue is present. Although we've been fortunate, no accidents have occurred, it is very unsafe for the owner and other drivers. This occurance has happended several times over the past year. Two times it was immediatley brought into the dealer service, the second time it did stall with the service member there. Both times they were unable to diagnose the problem and stated no error codes were reported. You have already issued a recall for this same issue with a different model. Oct. 13, 2017 – Hyundai motor America has recalled more than 400 vehicles potentially equipped with defective crankshaft assemblies, according to documentation submitted to the national transportation safety administration. There are so many others that have reported this same issue and have been corrected with the replacement of the crankshaft position sensor. . Read more...

The contact owns a 2025 Hyundai Elantra. The contact stated that while his wife was pulling into a customer's driveway at 5 mph, the vehicle stalled and rolled back and crashed into a parked Ford f-150. The brake pedal was applied, but the vehicle failed to respond. The vehicle failed to restart. There were no warning lights illuminated. The collision feature failed to engage. There was no fire or airbag deployment. A police report was filed. The driver sustained injuries to her neck and shoulder, and medical attention was provided at the hospital. The vehicle was towed to a tow lot. The local dealer was contacted, but the vehicle was not diagnosed or repaired. The manufacturer was contacted, but no additional assistance was provided. The failure mileage was approximately 4,000.

I was driving and I felt my car sputter and lunge forward slightly. Then my car lost power and when I pressed down on the accelerator it would not give out any power. The battery light came on and the car would not start after pulling over.

My vehicle is a 2019 Hyundai Elantra. It has the Hyundai nu 2. 0l engine, which has been the subject of recalls for engine failure, stalling, and sudden loss of power. The check engine light came on but not before the majority of the dangerous driving conditions surfaced, meaning I had almost no warning before the issue put my life in danger. My vehicle was not included in the recall even though other models with the same engine had been. I experienced unpredictable stalling, hesitation, and engine failure while driving. On several occasions, the car stalled unexpectedly in traffic, creating a serious safety risk; I nearly was rear-ended multiple times. The vehicle became increasingly unreliable, prompting me to take it to the dealership. The dealership confirmed that the engine failure was consistent with the known nu 2. 0l engine defect. There was metal debris in the oil even though I have kept up with maintaince and oil changes at the regular intervals suggested by Hyundai guidelines. Hyundai covered approximately 90% of the engine replacement under a “good faith” adjustment. Documentation of engine inspection and repair available upon request.

The contact owns a 2020 Hyundai Elantra. The contact stated that while attempting to turn at approximately 5 mph, the traction control warning light illuminated. The contact pulled over to the shoulder of the road and restarted the vehicle; however, the vehicle failed to accelerate as intended while the accelerator pedal was depressed. The check engine warning light was illuminated. The vehicle was towed to a local independent mechanic, where it was diagnosed with excessive oil consumption, catalytic converter failure, and related the failure to NHTSA campaign number: 21v301000 (engine). The local dealer was contacted however, the VIN was not included in NHTSA campaign number: 21v301000 (engine). The vehicle was not diagnosed or repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 89,709.

I started to see the oil light on the dashboard and I heard a hard sound from the engine so that I changed the oil then after a couple days I saw the light again on with a little bit high temperature, so stooped by a gas station and I added some more oil after I shut the car off and waited to cool the engine down and I started the car, the oil light was gone and the engine sound was smoother then I started to get the same issue every couple days and I used to fix it the same way and I've had the same experience with my previous car which was the same brand but different year band model which I found a recall on the engine after it blown and the agency or the manufacturer changed the engine for free for that car and the current car has the same issues and it's included in the year range for that recall which from 2012 to 2019, that scares me because I drive everyday for rideshare and that can be dangerous for me and my clients who ride with me, also some of them stopped calling me for rides once they knew about that issue. And today I noticed the car beep which I used to hear when I lock the car with the remote has stopped too.

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.

The contact owns a 2020 Hyundai Elantra. The contact stated that while driving at an undisclosed speed, the vehicle hesitated and lost automotive power. No warning lights were illuminated. The local dealer was contacted; however, the vehicle was not diagnosed or repaired. The contact stated that an appointment with the dealer was scheduled to inspect the vehicle. The manufacturer was not made aware of the failure. The failure mileage was approximately 68,000.

My oil plug fell out causing engine damage. They are saying it is fault of wal mart who did last oil change but 2 months and 12,000 miles have passed since oil change and they will not cover under warranty.

I am filing this vehicle owner's questionnaire (voq) regarding critical safety defects in my 2018 Hyundai Elantra related - 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 - 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.

Car had check engine come on with no significant symptom. Mechanic said this code leads them to either timing chain, phasers, or piston valve all located in the engine. The car does not have much time at this point. It’s very costly after just having changed all the oil gaskets from a leaky engine. Mechanic said it will suddenly get bad if left unpaired and could be dangerous for me while driving.

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.

Engine timing chains are failing in a direct result from recall campaign id 21v301000 piston ring noise sensing system which contaminated my oil accelerating wear on my engine chain and sprockets. A failed or ineffective piston ring noise sensing system can let piston/ring damage go unchecked, leading to oil contamination, which in turn wears out or destroys the timing chain system.

The contact owns a 2019 Hyundai Elantra. The contact received notification of NHTSA campaign number: 21v301000 (engine); however, the part to do the recall repair was not yet available. The contact was stationed in guam when the vehicle was purchased. The vehicle was manufactured in south korea. The contact then moved to the USA, and the vehicle was taken to colorado however, the vehicle was registered in florida. The dealer was contacted and refused to repair the vehicle, because the vehicle was considered a foreign vehicle. The manufacturer was not made aware of the issue. The contact had not experienced a failure. Parts distribution disconnect.

Large amount of oil consumption. Told by dealership that engine replacement is needed.

The issue involves the hybrid electric powertrain or electrical control system in my 2023 Hyundai Elantra limited hybrid. The vehicle has shut off multiple times while driving, with complete loss of power and propulsion. This poses a serious safety risk, as it happens without warning in the middle of the road. Restarting the car requires shifting into park and trying multiple times to turn it off, but the vacuole turns back on the first try. I have experienced this issue several times, including twice during a 300-mile highway trip. After each shutdown, the dashboard displays multiple warning lights, including the check engine light, battery light, oil pressure light, and hybrid system warning (orange car icon). I took a photo immediately after the most recent failure to document these warnings. The vehicle has been inspected three times by two different Hyundai dealerships. Both confirmed the vehicle is under warranty but have not repaired or diagnosed the issue, citing that they cannot replicate it. They have driven it ~200 miles without success. However, they have not pulled ecu data or freeze-frame codes, even though warning lights were active at the time of failure. There are no symptoms or warning messages before the failure — the vehicle shuts off suddenly. The car is available for inspection, and I am in the process of opening a formal case with Hyundai. This is a significant and recurring safety hazard that must be addressed. This issue has an occurred a various speeds including during acceleration and braking. The picture attached is the dashboard after the I indent has occurred and have shifted to park after stopping to try and restart the car to get out of the middle of the road.
