The contact owned a 2008 Hyundai Elantra. The contact stated that upon pulling into the driveway, the power steering and abs warning lights illuminated. After researching the warning lights online, the contact turned off and exited the vehicle. The contact became aware of smoke coming from underneath the hood. Upon opening the hood, the contact noticed that the under hood was on fire and called the fire department. The fire department arrived on the scene and extinguished the fire. The contact was informed that fire had originated under the dashboard nearby the computer. The vehicle was inspected, towed, and then deemed a total loss by the insurance company. The contact stated that the vehicle was previously repaired for an engine overheating failure two weeks prior to the fire. The failure mileage was approximately 115,000.

Vehicle is still in my possession and available for inspection upon request. My safety and the safety of others was put at risk due to vibration when braking caused by warped rotors, a vehicle that pulls to one side with an off-center steering wheel, abnormal tire wear including a bald tire with a sidewall bubble, and a transmission that has twice failed and recently felt like it was going to stall while accelerating. The wheel bearing/suspension noise was confirmed by an independent repair shop (firestone) using a listening device at highway speed; however, the dealership's own inspection gave a conflicting finding of no issue. The transmission issues have been reproduced by the dealership in the sense that two replacements were performed; however, the most recent stalling sensation has not yet been independently confirmed. The vehicle has not been inspected by police or insurance. Warning lamps/symptoms included a horn malfunction (tied to Hyundai TSB 25-be-005h-2) and headlight issues that coincided with transmission slipping on more than one occasion. These symptoms first appeared at approximately 10,000 miles with a wheel alignment flag, and have recurred and worsened over time, including three wheel alignments, two sets of front tires, and two rotor replacements.

I have a 2023 hyundal Elantra sel and my rear camera starts flickering and also goes blank frequently. In fact nowadays it is rarely working. I understand that there was a recall for 2021 and 2022 but not for 2023 yet. However it seems the issue continues with 2023 as well cause when I google I see I am not the only one having this issue. I called the dealership and because I am out of warranty they say they will charge as there is no recall for 2023.

2023 Hyundai Elantra sel. Car has been slow to start this week. When I depress the brake pedal and push to start, it will start then shut off in the middle of starting then I have to try again or it will sputter then fully start but every safety alert and electrical alarm will go off in my car and nothing clears it until I drive for about 5 minutes then they all clear. I went to autozone and they said my battery was normal health. When this slow start happens I also notice that my vehicle doesn’t accelerate as well and it feels like it’s trying too hard to the point it will jerk forward even when I’m only lightly pressing the accelerator. I noticed this, 2 winters ago (2024) as well and I thought it was due to the very cold weather we had. Brought it to my sister’s fiancée and he couldn’t find any dtc’s but agreed something felt off. The problem stopped and now it’s the middle of summer 2 years later and doing the same thing, to the point where I’m trying to merge onto I-95 and my car isn’t accelerating fast enough and I almost got rear ended!! it only happens at speeds under 50 and is extremely unsafe to have a vehicle where you don’t know if it will just turn off while you’re driving, stop accelerating or decide to not start that morning!!!.

Horn not functioning. Engine mount needs replacement.

I own a 2022 Hyundai Elantra with only 72,000 miles my check engine light came on for the code p048900 for the egr valve. It is no longer covered by any warranties but other year models have been recalled due to the same issue.

The horn is intermittenly failing and was verified by a weimer Hyundai in morgantown, wv on xxx. This is a known defect in 2023 Hyundai Elantras and they have issued an extended warranty to address the problem. An absence of a horn is a safety issue as you cannot signal other drivers in emergency situations. It is unlawful to have a horn that does not operate in most states including wv ([xxx]) which is where I currently reside. While a horn is not required by NHTSA , if it is present it must be operable by driver (safety standard no. 101, 49 cfr '571. 101). For these reasons I am requesting that this should have and should be considered a safety recall which is not predicated on mileage. By issuing an extended warranty that stops at 120,000 miles Hyundai does not serve those with higher mileage vehicles. It is not fair for a driver to have to pay out of pocket for a known defect that should have absolutely been addressed as a safety recall. Hyundai has been contacted and I was given a case #42976455 and a case manager named edward. Weimer was incontact with either him or Hyundai directly and they offered to split the cost of $600. 00 intead of taking full responsibility. I have no full time job and cannot pay anything (nor should I have to) for a safety issue. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

My 2024 Hyundai Elantra limited keep slamming the breaks and Hyundai keep running me in circles and won’t fix it. I fear my vehicle will cause a collision. A case with Hyundai has been open for over 3 months.

Apparently a very common crankshaft angle sensor malfunction caused the engine to stall out at a stoplight, putting me in harm's way.

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 control panel /radio panel has had a glitch or blacked out screen where it wouldn't come back on for a few hours and I could smell electrical or plastic burning after it did come back on after that the radio started changing channel on its own while screen glitched on and of with saturated static wrench on my dash comes on periodically. The tires pressure unit never has the same amount of air in it according to the gauge. Even though I have made it so that they were all equal several different times. The car feels like it misfires when that it's 9500° outside and you go for any sort of extended drive past 10-15, mi. When the air conditioner is on high, the fuel economy doesn't seem to match the way it's supposed to and some of the programming is missing since the last time it was serviced out of the control panel. Some options that we're supposed to have been there aren't there anymore and I'm pretty sure that when I use the remote to roll down my windows they're all supposed to roll down. Well only one of them does and it doesn't roll it back up the way it's supposed to when that it is foggy out. My camera system says that I'm about to get into a crash and starts blinking at me and beeping and flashing saying that I'm about to crash because my forward safety system or my rear safety system is not working properly. And yes I've let them know about these things my car has less than 25,000 mi on it and the problem started probably 3 months after I got it. When I first got it there was a bunch of little pits in the glass or I want to say hairline bubbles. I don't know what else to call them but they replaced my windshield. They didn't replace the back window that still has them.

Door lock actuator, the door latch is stuck on unlock and it won’t close or lock when the lock button is pressed on key fob.

Vehicle was serviced to remediate recall 271- backup camera replacement in January, 2025. In June 2026, vehicle is exhibiting the same issue. Rear camera is non functional in the following ways: 1. Vehicle is shifted to reverse, backup camera does not function; 2. Vehicle is in park backup camera button is pressed, backup camera does not function.

I woke up to my neighbor banging on my door that my car was on fire. My car was in flames. The fire department had already been called. The entire front of my car as well as the interior was completely destroyed.

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.

The vehicle's security system malfunctioned immediately after service at parks Hyundai of gainesville on 05/27/26 for recall 256 & campaign p33. The alarm blares & emergency lights flash while I am driving on public roads. This defect first presented in the dealership parking lot upon pickup. This creates a severe safety risk: the high-decibel alarm is a major distraction, the flashing lights confuse other motorists, & the malfunction prevents me from using turn signals, violating safety protocols. I demonstrated this to the service manager on 06/10/26. While the technician acknowledged the defect during a road test & performed a 'cap reset' (documented on the repair order), this attempt failed to resolve the issue. Despite this, the service manager refuses to acknowledge the defect, claiming it is an 'intended feature' of a 2023 recall at a different facility (993). This contradicts the technician's findings & my years of incident-free driving until the work on 05/27/26. The dealership initially omitted my return visit from their records, only acknowledging it after I confronted them in writing. An independent shop confirmed this electrical failure likely stems from p33, but requires proprietary dealer tools to diagnose. Attached video proves the vehicle runs while the alarm blares, confirming no relation to old campaign 993 logic. Attached repair order proves the technician acknowledged the defect & attempted a repair. Despite this, the service manager ignores the documentation, his own technician's findings, & my demonstrations, blaming my locking habits while refusing a deep diagnostic. After 16 days in their possession, neither the dealer nor manufacturer has provided a remedy. If this malfunction were an intended feature, it would be an ongoing hazard; it creates a distraction, causes a panic response, & prevents the adequate use of turn signals while in operation. The vehicle is unsafe, & the dealership & manufacturer have failed to provide a valid repair.

The engine failed on a 2015 Hyundai Elantra with approximately 71,000 miles. The vehicle has an open, unresolved safety recall (recall 251, NHTSA #23v651000) for an abs module brake fluid leak that Hyundai has acknowledged but has not provided a remedy for. The vehicle is currently at an independent repair facility and is available for inspection upon request. The vehicle repeatedly shut off without warning while in motion and restarted mid-drive, causing sudden loss of power steering and power brakes while driving. This occurred on multiple occasions and was documented by an independent service center in February 2026. This presents a serious risk of accident, injury, or death to the driver and others on the road. The check engine light was illuminated. The vehicle experienced recurring brake issues requiring multiple repairs over several years, including brake replacement before 2026 and rear rotor, brake pad, and brake line repairs in February 2026. These brake symptoms are consistent with the known abs module defect covered under open recall 251. The engine shutoff symptom was first documented in February 2026 and continued until engine failure in may 2026.

Vehicle was parked and turned off in a residential driveway when a fire spontaneously ignited in the engine compartment. There were no warning lights, unusual sounds, or symptoms prior to the incident. The fire department responded and extinguished the fire using dry chemical suppressant and water. The vehicle was a total loss. The fire appears to have originated in the front engine compartment area. The vehicle was not involved in a collision. The vehicle has a 1. 8l nu dohc engine and 4-wheel abs system. This vehicle falls under known NHTSA recalls and class action litigation related to spontaneous engine fires in Hyundai Elantra vehicles, including issues related to defective abs/hecu modules and engine defects associated with the nu engine series.

The contact owns a 2024 Hyundai Elantra. The contact stated that while driving 40 mph, the tachometer, the odometer, and the power steering became inoperable, nearly causing the contact to drive off the road. Additionally, the turn signal lights were not functioning. All the warning lights were illuminated after the failure. The vehicle was taken to the local dealer, who was unable to duplicate the failure after a 100-mile test drive and returned the vehicle unrepaired. The failure persisted, requiring an aaa tow back to the dealer, who again failed to duplicate the failure during a 3-mile test drive. An independent mechanic informed the contact that the diagnostic trouble codes needed to be reset with a vehicle scanner. The vehicle was not repaired. The failure mileage was approximately 21,000.

I own a Hyundai Elantra with approximately 103,000 miles. The vehicle has developed an intermittent issue where the engine will suddenly stall while driving. This most often occurs when I am decelerating and turning, such as when entering or navigating roundabouts. At the time of the stall, multiple warning indicators appear simultaneously, including the check engine light, battery warning light, and a “no key detected” message. There are no prior warning signs before the failure occurs—no unusual noises, no loss of power leading up to the event, and no dashboard warnings in advance. The stall is sudden and unexpected. When the vehicle stalls, I must quickly shift into park and restart the engine. The car restarts immediately without hesitation, and all warning lights disappear. The vehicle then operates normally again until the issue randomly reoccurs. This has happened multiple times. This issue creates a safety risk because the vehicle loses power unexpectedly while in motion, particularly during low-speed turns and in roundabouts, which could increase the risk of a collision due to sudden loss of propulsion and reduced control. The problem has not yet been formally diagnosed by a dealer or independent repair shop, but based on research and similar reported cases, it may be related to an intermittent engine or electrical signal failure. The issue has not yet been inspected by the manufacturer, police, or insurance representatives. Unknown as to the exact failed component, but the failure appears to involve a sudden loss of engine operation without warning, followed by immediate recovery upon restart.

Within a matter of a few days my car has been stopping by itself. The car was smoking and stopping in the middle of the highway, my dealership is proving me with a new engine but is trying to have me come out of pocket for an fuel injector, please help !.

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).

The horn on my vehicle all of a sudden does not work. Im afraid that I'll be in a accident because im unable to blow it. Plenty times ive almost been in a accident & it was literally nothing I could do because my horn isnt working. Secondly, something is going in with the suspension on the right side of my car. Too much rattling noise. I see in the complaints im not the only one having this issue. Third but not least, the ac isnt working. Blowing out hot air. Ive also seen where alot of people is complaining about that ive had this car only a year and it has too many recall issues.

My vehicle has been in the shop here at mcgrath Hyundai in chicago, IL 30+ times since I bought it 5/21. Electrical, (rear), 6 horns, 6 blower motors, multiple warranty and recalls and now my front driver seat belt. They’re refusing to fix it even though I have reported it before. They’re saying over 60,000 miles makes it no longer under warranty. I reported it before and they said that it was okay. It was not okay and still isn’t okay and they think I’m going to pay $1500 to get it fixed now as well as re wiring the back of the vehicle for $600, which I have been reporting issues with for years.

There was a recall electronic power steering (eps) motor connector that was being done for 2017 Hyundai Elantras and my car is affected by it. Hyundai is saying my car is not affected by the recall that they put out for this issue.

Electrical component with car has been malfunctioning. Adas system malfunctioning (all the lights on the dash have been coming on in and out at different times) despite turning the car on and off. Video and picture evidence has been collected on different days and times this issue has been happening. Blinkers do not work when this is happening. Concerned for safety while driving. Hyundai dealership is not helping and blowing me off.

[xxx] is subject to safety recall 20v-755 Hyundai recall 251 for a defective abs module that may leak brake fluid, cause an electrical short, and increase the risk of an engine compartment fire. The recall remains open and has not been performed. On Feb 2, I brought the vehicle to mcgovern Hyundai of arlington and disclosed an active brake fluid leak consistent with recall 251. I also stated that brakes were recently replaced 4 weeks ago. The service advisor incorrectly said the recall was just for a fuse and unrelated to brake fluid. The dealership drove the car for a state inspection despite knowing about the leak and open recall. They stated the brakes are bad and requested payment for a diagnostic, which I declined. No diagnostic testing was performed. The dealership informed me the required abs module part was unavailable and instructed me to return Friday, waiting 3 5 business days. The recall repair was not completed, and no towing or alternate transportation was offered. The dealership invoice documents the incomplete repair. I live in east boston, MA, a densely populated urban area with street parking. If the defect causes a fire, it could endanger nearby vehicles, residences, and public safety. I am filing this complaint to document the unprepared safety defect, dealership misinformation, and ongoing community fire risk. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

No accident has occurred as of yet (for my case). Ongoing issues with Hyundai left brake bulb and center brake bulb burning out due to over-amperage. These two are on their own 10a circuit separate from the 5a circuit for the right brakelight bulb. It appears that these two bulbs are possibly receiving 15a and therefore burning out prematurely (3 months or less). I recently replaced these two bulbs at the same time, and now my battery is shorted. To keep my battery charged, I need to pull my 15a brake lamp fuse while the car is parked. This has now caused my abs light to come on, as that system relies on the signal from the 15a brake lamp circuit. I suspect that some 15a components (10a+5a) received 20a (15a+5a) and welded shut. I am still looking for it to trace it down, resources are limited and I'm intent on just buying the $35 diagnostics book. Hyundai dealership did not inform me that this fuse was pulled while I drove home from the shop yesterday, creating an unsafe condition. They quoted me $500 to replace a brake lamp relay and the abs (I'm assuming the whole abs, but maybe just the control module), I declined. My plan for now, as this car isn't driven much, is to trace it down and find the shorted component. From my research, this is clearly affecting many years of Hyundais and kias, not just my Elantra and not just my year. In fact, it's so common that there are facebook groups (such as this one [xxx] ) dedicated to helping owners remedy this defect. I think a recall service, and a full investigation of what is electrically wrong with these cars, and what the actual remedy should be, is necessary based on the amount of cars that could be impacted. Hyundai & kia technicians I am sure are intimately knowledgeable about this issue by now and us owners are on the hook, having only 80,000 miles of warranty on anything purchased used. Please reach out with any add'l questions. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

1: driver’s window: don't go up or down, it doesn't respond to control. 2: headlight warning lights is on all the time because bulbs are burn out so soon after replacement .

My fiance and I, bought the vehicle in may 2022? from carvana. His name is [xxx] . Mine is [xxx] (maiden - [xxx] ) price. [xxx] passed away August 6, 2025. I wanted to mention this part before I explain the problem. His son is supposed to sign the car over to me as soon as court proceedings are finished. I love the car. But the car came from carvana with 17k miles. It currently has 42,000k miles on it. I only drive it around town. I live in tulsa, oklahoma. The city is notorious for pot holes. However, I do not think this is a pot hole issue. Around December 2025, the car steering wheel started shaking vigorously. When we purchased the vehicle, the right cv axle was needing to be replaced. Now, I am not sure what the problem is, but I hate to have to trade the car in. This was my very first Hyundai experience, and I want to keep the car for forever, because of my fiance. But I may have to trade her in. I have come to a few conclusions on my own. 1) tires - so I had them replaced. 2) warped brake rotors 3) worn suspension components 4) worn electric steering column coupler. I wanted to give you the VIN because since it is an older vehicle (but like new to me), it may have had a recall. I do not want to keep this vehicle if it is a problem. But I also do not want to give it to anyone else since my fiance bought it for me. To whome this may concern - if you happen to actually read these "complaints" could you give me a call at [xxx] [xxx] ) or my email: [xxx] [xxx] [xxx] I would honestly like to know if this is a huge issue with the car. At least that way I can prepare myself to sell it. I am overall very pleased with the car, except this issue is a big one, and [xxx] is not here to guide me into a decision with it. Thank you kindly, [xxx] information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).
