I own a 2022 Hyundai Elantra N Line. The HVAC system began malfunctioning when the center/forward-facing dashboard vents stopped producing airflow, while the side vents continued to work. Changing the HVAC mode does not properly redirect airflow to the center vents as intended. The vehicle was inspected and diagnosed, and I was informed that the ventilator lever/mode mechanism is broken or not functioning properly. This appears consistent with a known issue described in Hyundai Technical Service Bulletin 25-HA-001H/26-HA-001H concerning the ventilator lever and loss of airflow from the forward-facing center vents. This failure affects my ability to properly control where air is directed inside the vehicle, including directing airflow toward the windshield for defrosting/defogging. This could potentially reduce visibility in conditions where windshield defrosting is necessary and therefore create a safety concern. The problem has been confirmed through a vehicle diagnostic inspection. The vehicle/component is available for inspection upon request. I have also found other Hyundai Elantra owners reporting similar loss of center-vent airflow and HVAC mode-control problems. The issue occurred without a collision or other known event that would have caused the component to fail. The repair is also unusually labor-intensive because the failed ventilator lever is located behind the dashboard and requires extensive disassembly just to access the component. I was informed that the repair would require at least 14 hours of labor, resulting in an extremely high repair cost for what is essentially a small mechanical component. The amount of labor required to reach and replace the lever makes the repair disproportionately expensive. Additionally, I have encountered multiple other Hyundai Elantra owners reporting the same or very similar symptoms, including loss of airflow from the center/forward-facing vents while the side vents continue to function. Suggests occurring issues.

Federal Safety Recall Fraud and Vehicle Endangerment Report Vehicle: 2022 Hyundai Elantra Blue Hybrid | Involved Dealerships: Earnhardt Hyundai North Scottsdale & Larry H. Miller Hyundai Peoria This complaint documents severe federal safety recall fraud and mechanical endangerment by authorized manufacturer franchise dealerships. In April 2025, Earnhardt Hyundai took physical possession of my vehicle for a federally mandated Hydraulic Electronic Control Unit (HCU) braking/cruise control safety recall. Staff verbally verified the recall was complete, but the physical invoice and subsequent written email admission from Service Drive Manager [XXX] confirmed the safety repair was completely omitted with "no excuse."To resolve this braking risk, on April 22, 2026, I brought the vehicle to Larry H. Miller Hyundai Peoria to have the uncompleted HCU safety recall corrected. Subsequently, on June 17, 2026, I returned to the Peoria facility for a warranty deck lid repair and a scheduled oil change.Upon releasing the vehicle on June 17, the Peoria service department actively jeopardized my hybrid engine integrity by installing an incorrect, out-of-spec oil fluid weight (5W30) and releasing the vehicle with a completely loose, unsealed engine oil cap. This gross negligence forced me into a dangerous 140-mile high-altitude mountain highway transit ([XXX] to Flagstaff) with a compromised engine bay, creating an immediate engine fire hazard and risk of sudden highway power failure. The loose cap and incorrect fluid were independently verified and caught on video by Milestone Auto Repair in Flagstaff.The manufacturer's franchise network is falsifying federally mandated safety recall records and releasing vehicles in life-threatening, non-compliant conditions. I'm requesting an immediate NHTSA investigation on both dealerships. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

- #11742526June 7, 2026ELECTRICAL SYSTEM, BACK OVER PREVENTION: WARNINGS
Vehicle: 2022 Hyundai Elantra Hybrid Safety Complaint: While driving on the highway, my 2022 Hyundai Elantra Hybrid displayed a warning message stating “Check Hybrid System. Stop Safely.” Immediately after the warning appeared, the vehicle lost power and acceleration. The car entered a reduced-power mode, making it difficult and unsafe to maintain traffic speed. The warning instructed me to stop the vehicle immediately. This occurred while I was traveling at highway speeds, creating a dangerous situation for myself, my passengers, and other drivers. The sudden loss of power could easily result in a rear-end collision or other serious accident because the vehicle is unable to accelerate normally and traffic may not have enough time to react. My vehicle currently has approximately 69,000 miles and is within Hyundai’s hybrid system warranty period. I believe this issue represents a significant safety risk and should be investigated, as other Hyundai Elantra Hybrid owners have reported similar failures. I am requesting that this issue be reviewed due to the potential danger it poses to drivers and the public. Mileage at failure: Approximately 69,000 miles.

Description of Incident: The vehicle is experiencing significant engine oil dilution by gasoline. Upon inspection of the dipstick, the oil level is consistently found to be well above the "Full" mark, and the oil emits a strong, pungent odor of raw fuel. This indicates that unburnt gasoline is bypassing the piston rings and entering the crankcase during normal operation, particularly in colder temperatures or during hybrid engine cycling. Safety Risk: The dilution of engine oil with fuel significantly reduces the oil's viscosity and lubricating properties. This creates a high risk of premature engine wear, rod bearing failure, and sudden engine seizure or stalling while the vehicle is in motion. A sudden loss of motive power at highway speeds poses a severe crash hazard to myself and other motorists. Attempts to Correct: I have noted that similar Hyundai models using the 1.6L platform (such as the Tucson Hybrid via TSB 23-EE-002H) have received software updates to address this specific issue. However, when contacting the dealer regarding my Elantra Hybrid, I was informed that no such software fix or service campaign currently exists for the CN7 Elantra model, leaving the safety defect unaddressed. Expected Resolution: Hyundai should be required to issue a recall or technical service bulletin for the Elantra Hybrid to update the Engine Control Unit (ECU) logic, ensuring the engine reaches and maintains temperatures necessary to prevent fuel accumulation in the oil.

Vehicle: 2022 Hyundai N Line Mileage at Initial Incident: ~17,000 miles Components Involved: Engine and Engine Cooling; Exhaust System / Emissions; Air Bags (SRS) I am submitting this complaint to document unresolved emissions system and Supplemental Restraint System (SRS) safety concerns involving my 2022 Hyundai N Line, as well as the manufacturer’s refusal to ensure proper diagnosis and corrective action following a documented dealer service error and subsequent warranty repair. At approximately 17,000 miles, a Hyundai-authorized dealership failed to reinstall an engine oil seal during a routine oil change. This error caused rapid engine oil loss at highway speed, activation of the oil warning system, and oil discharge onto the roadway. The incident is documented in Hyundai service records and is not disputed. Sudden oil-loss events of this nature are known to cause latent or progressive damage to internal engine components and federally regulated emissions systems, even when immediate engine failure does not occur. Despite proper maintenance after this incident, the vehicle subsequently set DTC P0420 (Catalyst System Efficiency Below Threshold – Bank 1) at a mileage far below expected durability. Hyundai replaced the catalytic converter under warranty. I requested diagnostic data, inspection findings, and documentation supporting the repair, but the dealership refused to provide anything beyond a basic repair invoice. Immediately following this Hyundai-authorized warranty repair, the vehicle developed a new drivability defect, specifically hesitation during acceleration, which was not present prior to the catalytic converter replacement. This indicates a post-repair nonconformity and raises concern that emissions-related components may not have been fully repaired or that additional systems were affected during the warranty repair process. When I returned the vehicle for evaluation, the dealership stated that it would not diagnose the vehicle unless an acti

There is an issue with mice getting into the front of the car. It smells like urine and is unsafe to breathe. I have cleaned out air filters monthly and find nests every time and have even found a dead mice. My car has nothing that would attract the mice. I have tried everything and spent so much money to prevent this from happening. Apparently with this car it is a known issue, and has not been fixed.

This 2022 Hyundai Elantra Hybrid poses an imminent fire and safety hazard due to catastrophic high-voltage system failures. On December 11, 2025 (Mileage: 54,527), the vehicle displayed a "Check Hybrid System" warning. The dealership diagnosed a swollen 12V battery and, critically, a melted power relay assembly and melted power cable. This indicates extreme thermal overload. The dealer stated they could not repair it independently and deferred to the Hyundai Engineering Team. This is the second major high-voltage failure. On March 23, 2024 (Mileage: 34,276), the vehicle suffered a total electrical blackout while driving at highway speeds at night. The vehicle lost all motive power, interior lights, and hazard flashers, leaving the car invisible in a high-speed lane. The high-voltage battery was replaced in April 2024, yet the system has failed again with melted wiring less than 20 months later. Despite a previous recall performed in August 2024 (Campaign 9B4 - BMS Software Update for 12V Battery Over Voltage), the electrical system remains unstable. The vehicle currently exhibits signs of thermal runaway. I have been informed by the dealer on Dec 16, 2025, that the wiring has melted, yet they initially refused to provide a repair order documenting these specific findings. This vehicle is a fire risk and a threat to public safety. I am requesting assistance in having this vehicle removed from the road immediately as it constitutes a public safety hazard.

- #11705871December 18, 2025FORWARD COLLISION AVOIDANCE: WARNINGS, FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL
I am reporting a safety-related defect involving the vehicle’s infotainment and forward safety systems. When this occurs, the vehicle also shows a “Check Forward Safety System” warning message. Diagnostic trouble code C162078 is triggered, indicating a front radar out of alignment. As a result, critical safety features such as Forward Collision-Avoidance Assist, Smart Cruise Control, and other radar-based driver assistance systems are disabled. This issue creates a significant safety risk because the driver is not alerted to potential forward collisions and cannot rely on active safety systems. The blank infotainment screen also prevents access to vehicle settings, warnings, and camera functions. In South Korea, this same defect has resulted in an official recall and free front radar replacement and calibration. However, in the United States, customers are not covered under a recall and are required to pay out of pocket for radar realignment or replacement, even though the issue is identical and a lot of time the issue came back 3 months later and customer have to pay out of pocket once again to fix the same issue. Many owners report receiving official recall notices in other markets, while U.S. owners must independently diagnose the issue. Dealers often state that the problem may be caused by radar misalignment after a software update or system fault. In some cases, cleaning or recalibration temporarily resolves the issue, but in other cases, full radar replacement is required. This inconsistent treatment places U.S. consumers at a financial disadvantage and allows a known safety defect to remain unresolved. I am requesting that NHTSA investigate this defect and require the manufacturer to issue a U.S. recall with free repair, calibration, or replacement, consistent with actions already taken in other countries.
