Lane DepartureApr 2026 · ODI 11731788Details +

I am filing a complaint regarding a safety recall repair for my vehicle that is not being handled in a timely or reasonable manner by an authorized dealership Delray Hyundai 655 NE Sixth Ave, Delray Beach. Vehicle Information: 2021 Hyundai Elantra SE VIN: [XXX] Recall Information: NHTSA Recall #24V879000 Recall #271 – Backup Camera Inspection/Replacement This recall involves a failure of the backup camera system, which directly impacts visibility while reversing and poses a safety risk. The manufacturer has indicated that a remedy is available; however, the dealership I contacted is refusing to perform recall repairs on weekends and is only offering an appointment more than a month out (scheduled for May 4th). Given that this is a safety-related recall affecting rear visibility, this delay is unreasonable and places me at continued risk while operating the vehicle. I rely on my vehicle daily and should not be required to wait an extended period for a safety recall repair that is already available. Additionally, limiting recall repairs to weekday-only appointments creates an unnecessary barrier for consumers who work standard business hours. I am requesting that this issue be reviewed, and that appropriate action be taken to ensure dealerships are providing timely access to safety recall repairs, especially when the defect impacts vehicle safety. Thank You INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Subject: Vehicle Safety Complaint – Engine Failure – Hyundai To Whom It May Concern, I am submitting a vehicle safety complaint regarding a serious engine failure involving my Hyundai vehicle. The engine experienced a failure significant enough to require replacement. This raises serious safety concerns, as sudden engine failure can result in loss of power while driving, increasing the risk of an accident. In addition: •Hyundai Motor America has not adequately addressed the issue •My case (#xxxx) remains unresolved despite escalation •I have experienced delays, lack of transparency, and no meaningful resolution Given Hyundai’s known history of engine-related issues, I believe this may represent a broader safety concern affecting other drivers. I respectfully request that NHTSA: 1.Review this incident as a potential safety defect 2.Investigate whether this issue is part of a larger pattern 3.Take appropriate action to ensure consumer safety I am available to provide documentation and further details if needed. Sincerely, [XXX] [XXX] [XXX] [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I am filing a complaint regarding an unresolved and ongoing issue with my 2021 Hyundai Elantra N Line. The vehicle currently has approximately 80,100 miles. This issue began when the vehicle had under 60,000 miles. At that time, I brought the vehicle to a Hyundai dealership because the check engine light was on and I was informed it was related to the EVAP system, specifically the purge valve. I spent approximately five hours at the dealership and was told the issue had been repaired. However, shortly after leaving the dealership, the check engine light returned with the same issue. Since then, I have attempted multiple times to resolve this problem. I even purchased a new purge valve and had it installed by an independent mechanic. Despite replacing the purge valve, the check engine light remains on and continues to report EVAP system issues. I also had a mechanic perform a smoke test on the system, which did not reveal any leaks in the EVAP system. The mechanic stated they could not determine why the system continues to show a purge valve or EVAP-related code and suggested that only Hyundai may have the tools necessary to properly diagnose the issue. I contacted Hyundai corporate customer service for assistance, but they informed me that each dealership is privately owned and they could not intervene or assist further. This issue has now been ongoing for approximately two years. I continue to experience the check engine light and now the vehicle is beginning to have drivability problems including vibration and jerking during acceleration. This unresolved issue also affects my ability to pass vehicle inspections if the check engine light remains on. I am requesting assistance in resolving this ongoing issue and receiving proper diagnosis and repair support from Hyundai so that the vehicle can be repaired correctly.

I owned a 2021 Hyundai Elantra N Line that experienced a recurring transmission issue. In warm weather conditions the transmission would intermittently slip and stutter, causing a jerky engagement when attempting to accelerate. In cold weather the vehicle operated normally without these symptoms. When the issue occurred, the vehicle would sometimes hesitate or fail to move forward smoothly when pressing the accelerator. This created unsafe driving situations, particularly when pulling into traffic or accelerating from a stop. On multiple occasions this behavior nearly resulted in rear-end collisions because the vehicle did not respond reliably to throttle input. The issue appeared to be temperature related, as the problem consistently occurred during warmer weather while the vehicle operated normally in colder conditions. Because the vehicle could fail to accelerate predictably, this created a safety hazard for myself and other drivers. I believe this may indicate a potential defect in the transmission system.

I bought my car at McGrath Hyundai in chicago in May 2021. It’s been in their shop 30 plus times for various and repeated issues. As of late, over the last 6 months, I have reported to them and to Hyundai, my drivers side seat belt won’t retract properly and the high mounted brake light warning continuously goes off, a dinging, stating that there is an issue. Hyundai and McGrath repeatedly misdiagnosed and refused to fix these issues when they were first brought to their attention when under 60,000 miles. NOW that the car is over 60,000 miles, conveniently they’re stating that it’s out of warranty and will cost $2k. The technicians and service advisor Christine Tonelli at McGrath, knowingly and willfully misdiagnosed my car, attempting to cover up the issues stating that there was no issue. They said the seat belt was fine and the wiring wasn’t the issue for the high mount d brake light and kept changing the bulb. They knew it should have known there was a seat belt issue with it not retracting and the same with the high mount d brake light. Suddenly after 60,000 miles, they now state I was right the whole time by telling me it will be $2000 to fix it. I have all service records and emails.

Vehicle Speed ControlJan 2026 · ODI 11712831Details +

How are you? The problem with our Hyundai involves the engine and engine control system. My vehicle is equipped with the same 2.0-liter Nu GDI engine that Hyundai recalled in other 2021 and 2022 vehicles for engine stalling, internal engine damage, and fire risk. Although my VIN is not currently listed, the engine itself is identical to the recalled engines and is available for inspection. Since early ownership, the vehicle has repeatedly hesitated, surged, and jumped when accelerating from a stop, especially at stoplights and intersections. This unpredictable behavior creates a clear safety risk because the vehicle does not respond consistently in traffic and increases the risk of a collision. These issues are ongoing and reproducible under normal driving conditions. The symptoms have occurred many times and were not isolated events. The vehicle has been presented for service and the issues described. No misuse or maintenance-related cause has been identified. Prior to and during these events, the vehicle has shown reduced power, inconsistent throttle response, and hesitation. At times, warning lights and engine behavior consistent with internal engine distress have appeared. These symptoms match those described by Hyundai, Consumer Reports, and NHTSA in recalls involving this same engine. Hyundai has already acknowledged that this engine defect can lead to stalling, seizure, oil leaks, and fire, and that warning systems may not fully detect the problem until damage has already begun. Because my vehicle uses the same recalled engine and exhibits the same failure characteristics, I believe it should be reviewed as part of a recall expansion or defect investigation.

Description of the Safety Problem: In the early morning hours of January 8, while driving my Hyundai vehicle, I ran off the road into a ditch. I was extremely disoriented and activated the vehicle’s built-in Blue Link SOS emergency assistance system for help. I successfully connected with a Blue Link operator and repeatedly told her that I did not know where I was and that I was scared and needed assistance. While I was actively requesting help, the SOS call was disconnected. After the disconnection, I attempted to reconnect using the SOS system but was unable to do so, despite the vehicle having power and an active, paid telematics subscription. The system did not reconnect or provide further assistance. I was forced to call 911 from my personal cell phone to obtain emergency help. This resulted in a delayed response and a $1,300 towing expense that I would not have incurred if the SOS system had functioned as marketed. This incident raises serious safety concerns. The vehicle’s emergency SOS system failed during an active emergency, disconnected while the driver was disoriented and requesting help, and provided no ability to reconnect. This defeats the purpose of an integrated emergency safety feature and could place drivers at risk of serious injury or death. I am reporting this incident so NHTSA can evaluate the reliability and safety of Hyundai’s Blue Link SOS emergency system during real-world emergencies.

I’ve had several instances where I get locked out of my car because the vehicle would not read the key. I tried fix the issue because I assumed it was a dead car or key battery but the same problems kept happening shortly after. I became aware of the issue with the horn not working, when I recently purchased the vehicle. I tried to contact the ALM dealership salesman to report the issue and they told me he had recently quit. They mentioned bringing it back to the shop but it wasn’t guaranteed that the issue would be fixed.

In addition to a cop pulling me over for not having my lights on and he asked me if I was playing with the lights since they were going on and off and luckily the cop did not give me a ticket when I explained and he saw the problem (he advised me to get on this website and to make a report). I have reported this problem to the Hyundai dealership for the past 3 years and I don’t even think they take the time to investigate. The dealership just keeps telling me that with another update in the software is going to get fixed. But that is not the case. This is a very dangerous problem that is going to get someone killed.

Electrical SystemMay 2025 · ODI 11661670Details +

I am writing to report a serious and ongoing safety issue with my 2021 Hyundai Elantra Hybrid that remains unresolved despite multiple visits to Hyundai service centers and independent repair shops. I’ve also found numerous consumer discussions online describing nearly identical issues with the same model and newer Elantra Hybrid models, suggesting this may be part of a wider systemic defect. The core issue lies within the vehicle’s hybrid system. Shortly after a recent system/software update performed at a Hyundai dealership, a warning message began appearing at random intervals stating: “Check Hybrid System.” This typically first appears after extended driving — often around 3 hours — but once it occurs, the issue worsens if I continue to drive. Each time the warning appears, the vehicle suddenly and drastically decelerates without driver input, becoming dangerously slow and unresponsive, even while traveling at highway speeds. This creates an urgent safety risk, as I have had to maneuver off the road quickly to avoid collisions. After the initial warning, if I attempt to drive the vehicle again without sufficient downtime, the warning reappears much more frequently — sometimes within minutes. The only temporary relief is to stop using the vehicle and allow it to rest for at least six hours, after which the issue may temporarily subside. In every case, I must use the 12V battery reset button to restart the car, which I suspect may be clearing diagnostic codes before they can be properly recorded. Notably, the check engine light disappears after this reset, even if it was previously displayed. Given that the hybrid battery is located beneath the rear passenger seat, I am deeply concerned that if there is an underlying thermal or electrical issue, it could pose a serious or life-threatening risk to passengers. To date, no dealership or technician has been able to duplicate or permanently resolve the problem.

Electrical SystemOct 2024 · ODI 11621050Details +

I am writing to file a formal complaint regarding a significant safety issue with my vehicle’s backup camera system. The backup camera consistently malfunctions, displaying glitchy images with distorted lines across the screen. This issue renders the camera essentially unusable, as it fails to provide a clear view of the area behind the vehicle, posing a serious safety hazard. This malfunction directly impacts my ability to safely reverse, especially in crowded areas where visibility is crucial. The camera’s unreliability puts pedestrians and other drivers at risk, as I am unable to fully ensure that my path is clear when reversing. I strongly believe this defect poses a significant safety concern that needs to be addressed by the manufacturer. I request that the NHTSA investigate this issue and take appropriate action to ensure that this problem is resolved for myself and the many other affected vehicle owners. Thank you for your attention to this matter.

Forward Collision AvoidanceSep 2024 · ODI 11614945Details +

Several times, including yesterday, my forward collision avoidance engaged by braking suddenly and strongly and INAPPROPRIATELY, almost causing me to be rear-ended. I was nowhere near the car in front of me, and fortunately due to traffic was traveling below the speed limit. This seems to happen whenever there is an overpass above the road. I have reported this to Hyundai, and they don't seem very concerned. Very dangerous. I would think there could be a software or sensor update that can correct this situation.

The windshield is damaged very easily when a small rock hits it on the road. It's been hit before the recall and the new windshield is damaged. It's a hazard especially if it can be easily cracked. I've had other vehicles that can handle small rocks on road ways. These are damages from tiny rocks. This windshield is very weak, the Crack continues to spread all over day to day.

One day I was on the highway driving and the front collusion safety warning appeared. I thought the warning went off because the sensor was dirty due to dead bugs. However, I pulled over and the sensor did not appear dirty. After awhile the sensor went off on its own. Then a few weeks late the front collusion safety warning appeared again while I was driving on the highway. The warning has not fixed itself. I cannot use my cruise control. I took it to the Hyundai dealership and they told the me senor is off alignment and it will cost $500 to repair because they have to remove the entire bumper. I have seen on Hyundai forums this is a common problem.

Over the past 4 months, this car's safety sensors have randomly activated on 4 different occasions. The car will suddenly brake when this occurs, which puts me and the other drivers around me at risk of crashing. Each time, I've taken it to a Hyundai dealership for repairs. They always claim they can't recreate the issue and don't fix anything. I've provided the dealer with pictures and videos of the warning lights on my dashboard. It doesn't seem to help them diagnose the problem.

My car has two warning lights on my dashboard. First one is Check Foward Safety system. Second one is Check Smart Cruise Control System. Both of them turned on when I was driving in the middle of a highway. These warning lights activated out of the blue, without any unusual circumstances.I cannot use my smart cruise control system and the car is not able to alert me about forward collision. This issue has already been addressed through a recall for my vehicle's model and year in Korea. My vehicle was produced in Korea and was imported to the United States; however, Hyundai has not issued a recall regarding the same problem in the United States. This is a safety concern, and Hyundai should repair it free of charge, and the company should compensate customers who have already undergone repairs for the repair costs.

Since last year around 55k miles, my backup camera has stoped working. The first incident happened as I was about to back out of my garage. I opened the garage door and put my car into reverse. As I looked down at the screen and began to back up, I realized the screen showed me an image of a closed garage door ever though the door was open. Almost as if it had taken a screenshot or froze. The second occurrence was similar except it was when I was parking in a job site parking lot. When I put my car in reverse to park, what came on my screen was the image of the highway about 15 minutes prior. I’ve had several experiences like this where the backup camera freezes, has static-like lines all over the screen, discoloration, or delayed effects. This is dangerous because if someone is looking down at the screen and doesn’t realize the backup camera is giving an incorrect output, this can result in an accident (whether it be a single car or multiple car accident). This is because you can end up hitting something/someone if you get delayed feedback on the camera and don’t realize.

Investigations

2 NHTSA investigations on record

Investigations are agency reviews, not findings that a vehicle is defective.

Loss of Motive Power

The National Highway Traffic Safety Administration (NHTSA) received a letter dated July 13, 2022, petitioning the Agency to initiate a safety defect investigation into loss of motive power allegations attributed to oil drain pan assembly failures on certain Hyundai Motor America, Inc. and Kia America, Inc. vehicles spanning Model Years (MY) 2005-2021. The Petitioners cited examples of complaints indicating that the subject vehicles were experiencing rapid loss of engine oil due to oil drain plug back outs, resulting in loss of motive power and/or catastrophic engine damage. Additional complaints were provided which alleged that the oil drain pans lack sufficient structural integrity and are susceptible to cracking. The petition itself can be reviewed at NHTSA.gov under ODI number 11481745. On September 12, 2022, the Office of Defects Investigation (ODI) opened Defect Petition (DP22-003) to evaluate the Petitioners’ request. The Petitioners have provided additional complaints within four supplemental letters dated January 31, 2023, March 21, 2023, May 23, 2023, and August 4, 2023. ODI’s evaluation included the review and analysis of the complaints and supporting information submitted by the Petitioners, as well as additional complaints submitted directly to NHTSA which referenced either the oil drain plug or a crack in the oil pan. After reviewing the available data, ODI has not identified evidence that would support opening a defect investigation into the oil drain pan assemblies of the subject vehicles. Based on a review of the available information, a loss of motive power resulting from an oil drain plug back out has not occurred between the initial sale of a vehicle and the completion of its first oil change. If during an oil change service, a technician fails to remove the existing drain plug gasket before installing a new gasket, it is likely that a proper seal between the drain plug and the oil pan will not be made. An improper seal between the drain plug and oil pan could lead to the backing out on the drain plug, resulting in the sudden loss of oil while driving. Additionally, the provided examples of oil pan cracks were localized to the immediate vicinity of the oil drain plug and/or appeared to be the result of direct-contact with a tool during servicing.  There is no information to support that a vehicle-based defect exists relating to the oil pan assembly, and instead the documented incidents are related to the failure to follow the proper maintenance procedures during oil change service. In October 2023, Hyundai published a Technical Service Bulletin (TSB) that provided detailed instructions for oil change service on its gasoline powered vehicles, specifically highlighting the need to remove and replace the existing drain plug gasket prior to reinstalling the drain plug. After a thorough review of the material submitted by the petitioner, the information already in NHTSA's possession, and the potential risks to motor vehicle safety implicated by the petitioners' allegations, NHTSA does not believe that a formal investigation is warranted. Therefore, the petition is denied. A Federal Register Notice (FRN) further detailing NHTSA’s reasons for denial of the petition will be published. The reference numbers for the complaints to NHTSA cited by the petitioner can be found in the petition submission documents in the public file for DP22-003. To review those complaints and the additional complaints ODI added to its evaluation which are cited in the Closing Resume ODI Report Identification Number document, go to NHTSA.gov.

Seat Belt Pretensioners May Rupture

On August 8, 2022, the Office of Defects Investigation (ODI) opened this Recall Query (RQ) based on 3 incidents alleging front seat belt pretensioners that may rupture during deployment, on model year (MY) 2020-2022 of various Hyundai and Kia Models, resulting in 3 injuries (note: one incident occurred outside the U.S. and its territories).Between October 2021 and March 2023, Hyundai and Kia have filed the following 11 safety recalls for pretensioner rupture: NHTSA Recall No. 21V-796, 22V-069, 22V-123, 22V-127, 22V-218, 22V-354, 22V-447, 22V-458, 22V-816, 23V-094, and 23V-210.Hyundai/Kia have stated that the abnormal deployment of the pretensioners is due to over-pressurization of the pretensioner pipe that can cause metal fragments to enter the vehicle occupant compartment, which can result in injury to vehicle occupants.The various makes/models covered by the above recalls include approximately 405,900 certain 2020-2022 Hyundai Accent, 2021-2022 Hyundai Elantra and Elantra HEV, 2021-2022 Hyundai Santa Fe HEV, 2022-2023 Hyundai Santa Fe PHEV, 2020-2022 Hyundai Venue, 2021-2023 Genesis G80, 2023 Genesis G80 EV, 2023 Genesis G90, 2023 Genesis GV60 EV, 2022-2023 Genesis GV70, 2021-2023 Genesis GV80, 2021-2022 Kia Sorento HEV, and 2022 Kia Sorento PHEV.In response to ODI's investigation, in December 2022, Hyundai notified ODI that they would be conducting testing to validate subject vehicle seat belt pretensioners. This evaluation included sled testing and software testing which was performed by Hyundai and its suppliers. The tests were intended to evaluate pretensioner deployment characteristics based on the unique deployment signature of the subject and peer vehicles. ODI met with representatives from Hyundai on several occasions during the investigation to discuss testing progress and data. As a result of the testing, Hyundai was able to simulate the pretensioner failures. It was determined by Hyundai during testing, the front driver-side and/or passenger-side seat belt pretensioners may explode upon deployment in the event of a crash which can cause metal fragments to enter the vehicle occupant compartment.Hyundai thus notified ODI of their decision to proceed with a safety recall, to expand the scope of the previous safety actions.In view of the recall actions taken by Hyundai and Kia, ODI concerns have been addressed. The agency reserves the right to take additional action if warranted by future circumstances.
