VISIBILITY/WIPER

Windshield wipers intermittently malfunction in the intermittent setting. The wipers stop at random locations in the middle of the windshield, pause, move a short distance, stop again, and behave erratically. This can obstruct the driver’s forward visibility. The problem occurs without snow, ice, or an obstruction on the windshield. A previous NHTSA complaint concerning a 2021 Hyundai Elantra describes essentially the same failure: wipers stopping midway and obstructing the driver’s view (NHTSA complaint 11685493/complaint record). A separate 2026 complaint involving a 2021 Elantra reported intermittent wiper operation along with other multifunction-switch functions, and the dealer diagnosed a failed multifunction switch (NHTSA 11726986). I believe this represents a safety-related defect in the windshield-wiper/control system and request that NHTSA investigate whether additional vehicles should be included in a safety recall or other corrective action. The problem persist to this day.

LANE DEPARTURE,BACK OVER PREVENTION

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)

ENGINE

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)

UNKNOWN OR OTHER

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.

ELECTRICAL SYSTEM,EXTERIOR LIGHTING,VISIBILITY/WIPER

Daytime and night time running lights turn off and on randomly with brights engaging random as well. Turn signals not operating but intermittently and wipers not turning on intermittently. This Started in Nov 2025. First time dealership could get it in was Jan 2026, stated Multifunction switch was bad and covered under warranty, now not covered after getting it in 3.5 months later. Due to the this being a known safety concern for Hyundai Genesis with extended warranty put in place, would love a review on Elantra as well because there are several spots in threads stating the same issue. Thank you for your time and consideration.

UNKNOWN OR OTHER,ENGINE

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.
