2020 Hyundai Elantra

Defect. Hyundai Motor America (Hyundai) is recalling certain 2019-2020 Elantra, 2019-2021 Kona and Veloster vehicles equipped with 2.0L Nu MPI engines. The piston oil rings may not have been properly heat-treated, which could result in engine damage.

Risk. A damaged engine may stall, increasing the risk of a crash. In addition, oil may leak onto hot exhaust components, increasing the risk of a fire.

Remedy. Dealers will inspect and, if necessary, replace the engine, free of charge. In addition, Hyundai will deploy Piston Ring Noise Sensing System (PNSS) software. Owner notification letters were mailed August 24, 2021. Owners may contact Hyundai customer service at 1-855-371-9460.

Defect. Hyundai Motor America (Hyundai) is recalling certain 2019 Ioniq Hybrid and 2020 Elantra vehicles. The right-side rear wheel lug nuts may have been insufficiently tightened, allowing the wheel to detach from the vehicle.

Risk. A wheel detaching from the vehicle increases the risk of a crash.

Remedy. Hyundai will notify owners, and dealers will inspect and, if necessary, tighten the lug nuts, free of charge. The recall began November 15, 2019. Owners may contact Hyundai customer service at 1-800-251-0871. Hyundai's number for this recall is 184.

Defect. Hyundai Motor America (Hyundai) is recalling certain 2020 Elantra vehicles. The lower control arm ball joint fasteners may have been insufficiently tightened allowing the ball joint to detach from the lower control arm.

Risk. A detached ball joint can cause a loss of vehicle control, increasing the risk of a crash.

Remedy. Hyundai will notify owners, and dealers will inspect and, as necessary, tighten the ball joint fasteners, free of charge. The recall began November 20, 2019. Owners may contact Hyundai customer service at 1-855-371-9460. Hyundai's number for this recall is 185.

The car went into 'limp mode' after rpm fluxuation. It's in the shop. Blake, a service manager at Temecula Hyundai, tells me it has "piston slap," which AI says is related to a piston ring recall for this car. Blake went on to say it has 2 power train issues (and needs a catalytic converter). NHTSA shows no recall, but whether engine or transmission, my daughter was nearly rear-ended due to this mechanical failure occurring on a two-lane highway at 55 mph. RE: Transmission (copied from Facebook): "Summarized by Meta AI " "Several 2020 Elantra owners describe shuddering, hesitation, and complete transmission failure at low mileage. Some report the car won’t accelerate from a stop or surges in RPM while cruising. Hyundai issued a recall for shifting issues that a software update can fix, but not all owners have been notified." It seems to me that the incident could have been transmission and the the engine 'piston slap' is conincidentally simultaneously discovered by Temecula Hyundai. Naturally, I conferred with AI as to the possibilities and found both transmission software recalls and a piston ring recall both a matter of record, but somehow not fully reported or complied with by Hyundai. Thank you for your attention to this matter.

2020 Hyundai Elantra, VIN [XXX], ~79,239 mi. On or about [XXX], while entering a parking lot at low speed on an incline, I pressed the accelerator but the car had severe power loss and then stalled. It would not move in reverse. All dashboard lights came on only after the stall. I restarted it; the lights cleared. It was towed to Westlake Hyundai, 3610 Thousand Oaks Blvd, Thousand Oaks, CA 91362; checked in Sep 29, 2026 8:59 AM. Dealer found engine oil below the low mark, no external leaks, DTCs P0302/P0304 (misfires cyl 2 & 4), and all spark plugs worn/fouled. They replaced the plugs and started an oil consumption test per TSB 23-EM-008H. Critical safety issue: the oil pressure warning light never illuminated before or during the stall, despite critically low oil. This removed my only warning to pull over safely. A sudden stall in traffic could cause a crash. The vehicle has the 2.0L Nu MPI engine covered by Recall 21V301 for defective piston oil rings causing excessive oil consumption and engine failure. My VIN is not included, but it shows the same failure. Vehicle is available for inspection. No police/insurance inspection. Manufacturer not yet inspected. Concern: engine defect and oil pressure warning system failure. Attached: Westlake Hyundai repair order/inspection.

Back in early July, I noticed a ticking sound coming from my engine so when I took it in to a Hyundai dealership, they told me the only way I could pursue any help further was by completing a oil consumption test, which I complied and paid for out-of-pocket very soon after within 48 hours my check engine light came on and was flashing. after pulling the code at an AutoZone which I have documentation of it was a P 1327 which signals that the car had entered limp mode. I very quickly reached out to Hyundai themselves and after going back-and-forth on paperwork, they assured me that since I had no coverage on the vehicle due to its mileageand that it was not produced in the same factory as the other recall vehicles with that same problem that they could not pay or help me with any of the services I would need done to my engine. They told me the only chance I had was by completing the oil consumption test, which would then put me and my safety at risk by driving a car with a faulty engine while it was also in limp mode. I’ve only had the car for about a year and a half when it threw the first sign at me and I’m now struggling to figure out how to afford a completely new engine all on my own with no financial assistance all because my car was not made in the same factory as all the other ones that have had the same issue. I have not been able to drive the vehicle in the last two months and it just put me into financial deficit, trying to figure out reliable transportation to get t

The contact owns a 2020 Hyundai Elantra. While driving at an undisclosed speed, the vehicle suddenly shut off without warning. The contact referenced NHTSA Campaign Number: 21V301000 (Engine) as a potential cause for the failure; however, the VIN was not included in the recall. The contact stated that the vehicle shook violently with an abnormal electrical wire burning odor. The manufacturer was notified of the failure. The vehicle was taken to an authorized dealer, where it was diagnosed with an engine starter failure. The engine starter was replaced; however, the failure persisted. The failure mileage was 102,474.

The vehicle entered limp mode. The Hyundai dealer diagnosed a camshaft problem, said the repair would be covered, ordered the part, and began the work. After the engine was opened, the dealer noted sludge/varnish and denied coverage, claiming lack of maintenance. This VIN is included in safety recall 21V301 for improperly heat-treated piston oil rings on the 2.0L Nu MPI engine. Hyundai told NHTSA that chipped rings can scuff the cylinder bore, cause accelerated oil consumption, knocking, oil-pressure warning, connecting-rod bearing seizure, stall, and in limited cases fire. The published remedy is inspection of the cylinder bore and piston skirt, engine replacement if damage is found, and PNSS software, at no charge. Hyundai National Consumer Affairs Case #XXX. I sent a written demand that they complete Campaign 203 and not convert an open safety recall into a customer-pay job. On XXX, case manager Mohammad issued a letter denying only “limited warranty” coverage for lack of Owner’s Manual maintenance. That letter does not state whether the Campaign 203 bore/skirt inspection was done, does not state whether PNSS was installed, and does not decide the incomplete recall. Oil and filter were changed on a regular schedule by the owner’s family using the specified oil. A signed affidavit was provided. Hyundai’s warranty does not require dealer-only oil changes. The symptom of the recalled oil-consumption defect (varnish/sludge) is being used to refuse the recall remedy. The vehicl

The contact owns a 2020 Hyundai Elantra. The contact stated that while driving 25 MPH, there was an abnormal rattling sound coming from the engine, with the check engine warning light illuminated. The contact pulled over to the side of the road. The vehicle was restarted but unexpectedly stalled. The vehicle was taken to an independent mechanic and was diagnosed with camshaft failure. The vehicle was towed to the dealer and was diagnosed with engine failure caused by a misfire. The contact was informed that the engine needed to be repaired. The vehicle was not repaired. The vehicle was taken to another independent mechanic and was diagnosed with camshaft failure. The manufacturer was not made aware of the failure. The approximate failure mileage was 46,691.

Transmission TCM/IVT had a service campaign recall #963 for TCM relearn / IVT replacement for premature transmission failure. Hyundai USA and dealership Big Star Hyundai of Friendswood, TX have made claims of the repair being done. Service records indicate there was no replacement, relearn or anything transmission related done with the vehicle and Hyundai USA has claimed on their end that their records show it was completed, but refuse to show or display records of completion, and have not maintained outreach to the dealership regarding maintenance records for this specific issue. Transmission has popped a P0867 code at 65,000 miles, just outside of it's warranty, and reflects the same codes listed for an issue regarding the TCM/IVT service campaign 963. The safety risk is the transmission giving way on a highway or some other location where it could potentially lead to an accident or stranding, that could lead to serious injury or death. This puts other vehicles on the road and passengers at high risk for an accident or incident. The problem has been reproduced by my husband, and confirmed with ECM readers. Independent service in Atascocita TX confirmed the check engine light indeed coincided with the P0867 code and that it has to do with the very same recall they have claimed to have supported and completed, which is once again not listed under any service completed on the vehicle. We are attempting to have this component looked at by the dealership, but they refuse to ackn

My 2020 Hyundai Elantra SEL experienced a total transmission/IVT failure at 81,185 miles. I paid $4,804.14 out of pocket to have the vehicle repaired at a certified Hyundai dealership, Dick Smith Hyundai Genesis of Greenville, now known as Hyundai of Greenville. The transmission was replaced with a new replacement unit. The replacement transmission has now suffered a second total failure at 117,922 miles, meaning the vehicle has experienced two total transmission failures before reaching 120,000 miles. The repeated failure of the IVT system is extremely concerning, particularly because the first replacement was performed by an authorized Hyundai dealership and the replacement unit failed after approximately 36,700 miles. I am requesting that this repeated transmission failure be documented and investigated. I also believe Hyundai should review the vehicle’s transmission history and consider the possibility of a systemic defect or premature failure involving the IVT system. I have already contacted Hyundai Customer Care regarding a Prior Repair Goodwill Reimbursement request for the $4,804.14 I previously paid out of pocket. Hyundai Customer Care case #43147944 was denied based on the vehicle being outside the factory warranty, although Hyundai directed me to the dealership for possible goodwill consideration. I am requesting full retroactive reimbursement of the $4,804.14 I paid for the first transmission replacement. I can provide the original repair invoice, service records

Steering wheel has been making whining noises when turning. Previously replaced worm shaft on steering while under warranty due to malfunction when first purchased. Issue has resurfaced but no longer covered under warranty. Dealer quoted nearly $800.00 to replace worm shaft.

Logic board failure part number 99211-F2000 leading to inoperable lane keeping assist and forward collision avoidance.

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

I have a 2020 Hyundai Elantra Limited that was purchased new in December of 2020, has 17,764 miles, and no damage. At the end of May/early June of 2026, the car gave warning messages for the following: check forward collision avoidance assist system, check lane keep assist system, and check high beam assist system. The car was inspected by the dealership, from which it was purchased, on June 29, 2026. The technician report says error codes C1604 and C1606 were found and that the car required replacement of the front camera system at the cost of $1991.49. Front camera failure negates the ability to use the advanced safety features of this car. These features are so important to alert and, more importantly, assist the driver avoid accidents and improve all motorists safety. I have read numerous complaints depicting the same problem with this front camera system. Hyundai issued TSB 20-BE-006H due to multiple problems just like the one that happened to me. I have corresponded with Hyundai about this situation and my concerns on why a car with this few miles and no damage had a failure of this magnitude. They are unwilling to assist due to the warranty expiring 6 months ago. For components this important to the safety of all drivers, I would like to see a recall established to hold Hyundai accountable for faulty components. Safety should not be limited by a warranty and last longer than 5 1/2 years. Than you for your consideration.

A few weeks ago, I was driving home on a 3-Lane local state route here in NJ from a family outing on a rainy dark evening when a large portion of the body paint from the hood flaked / peeled off and somehow got stuck under the drivers side windshield wiper as they were on during the rain at highway speed. It was a large enough piece (at least 3" wide) , to not only get stuck under the wiper, but create a serious issue for me to see out the windshield where the wiper wouldn't clear my vision out of the windshield. I managed somehow to safely pull to the side of the road and get out to inspect what it was.. I was able to remove the large piece of peeling paint from under the wiper but it did ruin the edge of the wiper blade which made for a treacherous drive home and I had to replace the wiper at a later date. The paint is peeling from all over my car (Hood, Pillars, Roof) and I've done my best to get all the loose pieces off but I'm afraid to drive it anywhere with the thought more paint will peel off with the wind & get carried to someone else driving behind me. My Hyundai Elantra is a 2020 and has only 48,526 miles currently. I contacted my local Hyundai dealer who advised me I am "Out of warranty for paint coverage" and suggested I further open a case with Hyundai Corporate, which I did, and was assigned a case manager who requested I take it back to my local Hyundai dealer in Avenel, NJ (Sansone) and have a service advisor/technician take pictures and submit them to Warran

Reporting on 2020 Hyundai Elantra. I have owned since 2023, my car is currently at a Hyundai certified dealership for it's 3rd transmission in the three years I have owned it. All 3 transmission were inspected and then replaced by Hyundai certified technicians. The Safety aspect is the inability to get you vehicle off the highway.

Currently, there are 30,564 miles on my vehicle and I am the original owner of the vehicle since early 2021. This is a continuous intermittent problem that can occur at any time when trying to accelerate the vehicle. The vehicle could be moving down the road and you go to accelerate and the RPM's drop dramatically, giving you no power. The same thing has happened when trying to accelerate from a stop. The vehicle would start to accelerate and then all of a sudden the RPM's drop, giving you no power. I have had the vehicle to the dealership for this problem and I am being told that they can't do anything about it because they can't duplicate it. If this happened when it was necessary for me to get out of the way of a vehicle, an accident could occur, resulting in sirius injury or death. Also, there were no warning lights or check engine light that came on at any time when the problem presented itself.

Around 9 p.m., I was driving home on the XXX highway at about 60 mph. The road was clear, with no obstacles ahead, and it was lightly drizzling in the [XXX] area. Suddenly, the car's emergency braking system activated, then returned to normal. Although it startled me, thankfully there were no cars behind me to avoid a collision.

The contact owns a 2020 Hyundai Elantra. The contact stated that while driving, the vehicle unexpectedly stalled. The vehicle was able to restart. The check engine light illuminated. The vehicle was taken to an independent mechanic Camshaft sensor failure. The camshaft sensors were replaced; however, the issue persisted. The vehicle was then taken to the dealer where it was diagnosed with engine failure but the vehicle was not repaired. The manufacturer was notified of the issue. The contact associated the issue with NHTSA Campaign Number 21V301000 (Engine). The approximate failure mileage was 105,000.

This complaint documents a recurring automatic transmission failure resulting in three complete vehicle shutdowns during active operation — two at highway speed and one in an active turning lane. The most recent failure occurred within 15 minutes of the vehicle being released from an authorized Hyundai dealership in College Park, Maryland, whose general manager admitted in a recorded call that the vehicle was released knowing the transmission was unrepaired and unsafe. The first failure occurred in 2025 on a highway with no prior warning. The vehicle was towed to the dealership, where the transmission was confirmed defective and repaired under warranty. The second failure occurred in January 2026, again on a highway with no warning. The dealership held the vehicle from January through May 2026 — four months — with no updates despite multiple owner inquiries. In April 2026 the dealership confirmed the transmission had failed again and was seeking Hyundai corporate authorization for the warranty repair. On May 21, 2026 I was told the vehicle was ready and the transmission had been fully repaired under warranty. This was false. On [XXX], within 15 minutes of leaving the dealership, the transmission failed a third time, completely shutting the vehicle down in an active turning lane with no warning. The general manager at Hyundai College Park later admitted in a recorded call that the transmission was never repaired and the vehicle was released only to recover the dealership's ren

I bought a 2020 Hyundai Elantra in 2024 with 67k miles on it. After driving 22k miles the check engine light went on and when it was brought in to get it checked the transmission went out. I did not buy a warranty so I understood it would not be covered. The issue I had was it was very hard to get information on the condition of the car that was sold to me. What I found out was that the transmission fluid was likley not changed ever and definetly not checked before the car was sold since the check engine light was not on and the engine sounded fine when I bought it. Which when I did meet with the service manager was informed of. The service manager noted that the IVT transmission has a long history of going out and is a bad design. He stated that most cars are not being made with it anymore and that this is well known problem. My biggest issue is that they knew this when it was sold and since the car was already over 60k when they got it should have at least checked the fluid or put in new fluid due to the history of transmission problems on the car. It is very likely this was not done to the likelihood the fluid was already bad and the transmission would have gone out so they wanted to pass it on to the customer. I know it is on me to know about a car when it is purchased but did not think of checking specifically on what type of transmission was in the car and now always will. I have had two Hyundai and both went over 200k without problem. To have one go 89k and go out was

The contact owns a 2020 Hyundai Elantra. The contact stated that while driving at an unknown speed and at a stop, the vehicle lunged forward. The RPM increased and decreased without applying the accelerator pedal. The check engine light was illuminated. A mobile mechanic reset the codes but was unable to determine the failure. The vehicle was taken to an independent mechanic who referred him to the local dealer. The local dealer was contacted, who stated there was a transmission pressure sensor issue. which prevents the service from being performed under Hyundai Service Campaign 863 T5B Bulletin: 20-01-028H. The manufacturer was contacted, but no additional assistance was provided. The failure mileage was approximately 76,000.

The Contact owns a 2020 HYUNDAI Elantra. The contact stated while operating the vehicle at an undisclosed speed, he noticed that his RPM were going back and forth while on cruise control, after removing cruise control the vehicle stayed the same. The vehicle was pulled over and restarted but the vehicle was hesitating to accelerate and noticed a issue with the gears not. The vehicle was towed to a independent mechanic but was not fully diagnosed due to the transmission driving forward when in neutral. The dealer was notified of the failure and a appointment was set for a later date. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 106,000.

I am submitting this complaint to document ongoing brake related concerns on my 2020 Hyundai Elantra that may affect vehicle safety. Since April 2024, I have experienced repeated brake rotor warpage that causes vibration during braking, reduced braking consistency, and a noticeable change in stopping behavior. These symptoms raise concerns about braking performance and overall vehicle control. I reported the issue to Hyundai Motor America and followed their required warranty process, including an inspection at High Desert Hyundai. The dealership indicated the condition should be covered under warranty, but I was charged twice for what should have been a no cost warranty inspection. HMA later denied warranty coverage based on an undefined claim of “outside influence” without providing any criteria, explanation, or evidence supporting that conclusion. The denial prevented me from understanding the basis of their determination or how it applied to the brake condition. HMA then directed me into the BBB Auto Line program under case number HYU2605570 as the next step for disputing the decision. Throughout this process, Hyundai did not provide any additional information or documentation explaining the cause of the brake condition or addressing the safety concerns I raised. Because braking performance affects stopping distance and vehicle control, I am reporting this issue to NHTSA so the agency is aware of the repeated brake vibration and rotor warpage, the inconsistent braking beha

I no longer have this vehicle, as I traded it in once I was able to lower some of my negative equity. During owning the 2020 Hyundai Elantra, a deer it the side of my vehicle and knocked me into the center of the road while I was driving. No airbags had come out, nor was any sensor activated. About 6-8 months later, I was driving down the same road and a deer had run across the road. The forward collision sensor did not alert me (I was paying attention to the road, but would have absolutely heard it), and my airbags did not deploy. My car suffered over $9,000 in damage and I had a concussion.

On January 1, 2025, I discovered my vehicle had been stolen after finding broken glass in my driveway and immediately reported the incident to the police, who arrived within approximately 20 minutes; neighbors later provided camera footage of the theft, and I also observed other nearby vehicles with similar damage, including a broken rear window and another Hyundai Elantra that appeared abandoned. The following day, police informed me the vehicle had been recovered, and upon inspection I found the rear driver-side window completely broken and the ignition area under the steering wheel damaged. Couple months later I received a recall notice for the antitheft system on my 2020 Hyundai Elantra (VIN [XXX] ). When I brought the vehicle to the dealership on April 1, 2026, I was informed that the recall cannot be completed unless an additional part is replaced, at a cost of approximately $1,178. This part was damaged during a prior theft incident. My vehicle was stolen last year and later recovered, and it sustained damage during that incident. However, I understand that safety recalls are required to be repaired at no cost to the owner under federal law. I am concerned that I am being asked to pay for repairs in order to complete a safety recall, and that my vehicle remains vulnerable without the recall remedy being performed. I am also concerned about the safety and legal compliance of continuing to operate the vehicle under these conditions. I am attaching supporting documents as

How can this not be coved under a recall when it is clearly a safety issue and many mentions on line with others having the same problem? The vin.# says there are no open recalls. How can I get this covered on my car that is the same model and year as others with the same problem. I see a couple service bulletin's and would like to know if any apply. Please respond with any help or suggestions on this matter as I need help from the NHTSA to get Hyundai to fix it. I am happy to send a video for proof. I look forward to your reply. Thank you very much!

The vehicle suffered a total, simultaneous failure of both low-beam and high-beam headlights due to a known manufacturer defect involving internal wiring and melted pigtail sockets. This matches the failure pattern described in Hyundai TSB 20-BE-004H and Service Campaign T5G (TSB 21-01-004H). ​On January 22, 2026, Robert Woodall Hyundai (Danville, VA) inspected the vehicle and confirmed on Invoice #[XXX] that "BOTH HEADLIGHTS ARE INOP". Despite this verification and the presence of technical bulletins for the ADa model line, the dealer refused the repair and refused to submit a Goodwill Authorization request as mandated on Page 2, Note 2 of the TSB. ​The Service Manager (Alan Pyles) claimed in an email that the TSB had "expired," despite the defect being active and documented in more recent campaigns. Releasing a vehicle with documented inoperative headlights creates an immediate safety risk for nighttime operation.

Vehicle has ongoing issues with headlights prior to purchasing, they claim to have repaired & satisfied recall, however, they replaced headlights with the same faulty part the replacement lights are the same, with same issues, no high beams they have a steel rod operating a plastic gear that operates a shutter to dim & operates high beam. The problem is with the heat of halogens the rod gets hot and melts the gear connection rendering the shutter inoperable so as it is , we get a year and a half out of them then they are junk. Dealer cost is 900 dollars each just for 1 light. If dealership installs 2000 dollars. The issue is, they didn't reengineer the unit! Just keep selling faulty parts! There is no way we should have to go through this every year and a half. So we're going around with no high beams ( I'm including all owners) many complaints. Foremost, it's an obvious safety concern! I've been to Bergstrom Hyundai 3 times called corporate HQ no results. In addition, the bulbs constantly burn out. I may get 4 months out of them before replacement is needed 40 dollars each suggesting a electric current surge issue idk for sure. In closing, the manufacturer must redesign the units. They should last the lifetime of the vehicle ( not the bulbs obviously). The high beam operation system. They need a push to motivate them to correct safety concern thank you!

This vehicle’s engine failed on 10/25/21. This was 2 months after it was purchased. When we tried to have a Hyundai dealership diagnose the car, they said it would be an extended amount of time before the could look at it. When they finally did, they said it was not eligible for the warranty or recall relief. I reached out to the Hyundai corporate office and received no assistance. They tried to say it was due to no drain plug. It was recommended that we take it to another dealership who said the same thing. We ended up paying out of pocket to replace the engine. The mechanic who replaced the engine said there was no oil splatter under the car that would indicate an oil leak. Now on 1/15/26, the 2nd engine has now failed for apparently the same recall. For either engine there was never any warning of low oil or any evidence under the car of a leak.

Paint is peeling off vehicle.

Engine is stalling and consuming oil at a higher then normal rate. Knock sensor is having issues at 24k miles both part of recall campaign 974 and recall 203. Took the auto to dealer for service and was told Hyundai would not honor the recall due to a branded title which now puts me in a scenario of possibly engine stall in the middle of highway traffic.

Reporting motor has a cold start ticking sound coming from the motor.
