(NHTSA Tracking Number 11726105) I am updating my existing complaint regarding my 2024 Hyundai Tucson (NHTSA Tracking Number 11726105) for an ongoing safety concern involving an intermittent warning chime while driving. This issue began shortly after I purchased the vehicle in Nov 2025 and has been reported to the dealership multiple times over several months. The warning chime occurs randomly while driving without any visible warning message or dashboard alert. This creates uncertainty because I do not know what the vehicle is trying to warn me about, which is distracting and creates a safety concern while driving. The dealership previously replaced both front seatbelt buckle assemblies after identifying intermittent high resistance as a possible cause. However, after that repair was completed, the warning chime occurred again while I was driving to the dealership for a follow-up visit. This confirmed that the issue was not fully resolved. I immediately returned the vehicle to the dealership, and they are now performing further diagnosis. I was advised that if the issue reoccurred, the next possible areas for diagnosis could involve the instrument cluster or the control module, both of which are safety-related systems connected to warning alerts and seatbelt functions. In addition, during this same visit, the dealership confirmed there is an actual oil leak requiring repair. This is significant because when I first raised this concern after an outside inspection in December 2025, I was told it was likely leftover residue from a prior oil change. The dealership has now confirmed it is a real leak and kept the vehicle for repair while providing a loaner vehicle. Because this vehicle was sold as Certified Pre-Owned and these safety and mechanical concerns continue shortly after purchase, I remain concerned about the reliability and safety of the vehicle.

While driving at approximately 70 mph on a highway under normal conditions, the vehicle experienced a sudden loss of engine power. A check engine light illuminated at the time of the failure, and the vehicle was unable to maintain normal acceleration or consistent speed. The loss of power created a hazardous situation in active traffic, as the vehicle could not safely maintain speed with surrounding vehicles. The vehicle was later inspected by an authorized dealership, which confirmed severe internal engine damage, including cylinder damage and engine misfire requiring major repair or replacement. No clear root cause has been provided. There were no prior warning signs or symptoms before the incident. WARNING SIGNS PRIOR TO FAILURE: NONE OBSERVED. The vehicle is available for inspection upon request. DEALER CONFIRMATION: YES. MANUFACTURER INSPECTION: UNKNOWN.

The same incident has occurred 4 times ( [XXX] While driving on the freeway in light traffic and no vehicles in front. The forward collision sensor triggered dropping the vehicle in speed approx 30 mph almost instantaneously. This is San Diego so no snow, rain or sleet and we were driving eastbound each time with the sun at our back. Hyundai kept the car for a week for diagnostics and found nothing. We have since escalated to corporate and are going in for another round of diagnostics. We have been exceptionally fortunate that we were not rear-ended. We have since installed a dash-cam to record the next event INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The contact owns a 2024 Hyundai Tucson. The contact received notification of NHTSA Campaign Number: 25V893000 (Trailer Hitches). The local dealer was contacted and confirmed that parts were on back order. The vehicle was not diagnosed or repaired. The manufacturer was not contacted. The contact had not experienced a failure.

Component: Engine/Powertrain/Electrical System Incident Description: I am reporting a recurring, life-threatening "Loss of Motive Power" (Dead Pedal) in a 2024 Hyundai Tucson (Alabama-built). On multiple occasions, the vehicle has failed to respond to throttle input during high-risk maneuvers, specifically while merging into 45+ MPH traffic. The vehicle "chugs" and stalls, refusing to exceed 15 MPH despite full accelerator depression. This defect leaves the vehicle and its occupants stranded and defenseless in the path of oncoming high-speed traffic. Technical Context: This vehicle is currently subject to NHTSA Recall 23V-526 (Hyundai Campaign 246) for electronic controller damage that can cause "CAN communication disruptions." I believe the "Dead Pedal" failure is a direct result of these communication disruptions between the engine and transmission control modules. Furthermore, Hyundai has issued TSB #24-AT-001H-1 for "Hesitation when accelerating," yet the authorized dealer (Ed Voyles Hyundai) has been unable to remedy the defect after 84 cumulative days out of service. Safety Risk: This is not a convenience issue; it is a critical safety failure. The unpredictable nature of the power loss makes it impossible to safely judge gaps in traffic. The vehicle effectively becomes a stationary object on active roadways without warning. Manufacturer Response: The manufacturer has been formally notified via certified legal counsel. Despite 79 consecutive days in the current repair attempt (since Jan 16, 2026), the manufacturer has failed to provide a fix or acknowledge the severity of the safety risk. An informal third-party evaluator attempted to dismiss the claim despite the vehicle's documented inability to maintain motive power. We are requesting that NHTSA investigate the adequacy of Recall 23V-526 and TSB #24-AT-001H-1, as these measures have failed to resolve this life-threatening "Dead Pedal" condition in my vehicle.

There has been an urgent safety recall with no fix for 4 months. I need the issue to be resolved so that my vehicle is no longer a safety hazard, but both the dealership I purchased it from and the manufacturer have stated that it's not a big deal.

The contact owns a 2024 Hyundai Tucson. The contact received notification of NHTSA Campaign Number: 25V893000 (TRAILER HITCHES); however, the part to do the recall repair was unavailable. The local dealer was contacted, and it was confirmed that the part was not yet available. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was made aware of the issue. The contact stated that the third brake light remained illuminated after the vehicle was turned off and the key was removed from the ignition. The tow hitch wiring harness was replaced but the failure persisted. The failure mileage was approximately 20,000.

The problem first appeared after I bought my car to the dealership to replace an amplifier. Since then, my car has been there twice and they have not been able to identify the problem. I’m going back-and-forth with the dealership and hyundai corporation. after numerous incidents with my other vehicles, I no longer trust this place to repair and at this time it’s a safety issue while I’m driving. I work in a school district in [XXX] when the kids are around I need my front and back up cameras to work. it’s a safety concern for me and I need your advice.

I am submitting a vehicle safety complaint regarding my 2024 Hyundai Tucson Hybrid. The vehicle has a recurring engine warning issue (code P0471) that has not been resolved despite multiple repair attempts by an authorized Hyundai dealership. Additionally, there is a concerning discrepancy regarding vehicle usage while in dealership custody. My records indicate a substantial increase in mileage during service, which is not reflected in official service documentation. This raises concerns about vehicle handling and accountability. Hyundai has declined to escalate or properly address the issue and has advised that they will continue repair attempts without further resolution. Given the recurring nature of the issue and the lack of accountability, I am concerned about potential safety risks. I respectfully request that this matter be reviewed and recorded as part of any ongoing safety investigations.
