UNKNOWN OR OTHER, EXTERIOR LIGHTING, ELECTRICAL SYSTEM
The multifunction/turn signal switch in my Hyundai has failed and causes the left turn signal to operate intermittently. While driving, I am unable to reliably activate the left turn signal when making a left turn or changing lanes. The signal may fail to engage when the turn signal lever is operated, requiring repeated attempts to activate it. College Station Hyundai inspected the vehicle and diagnosed the multifunction switch as the failed component requiring replacement. The replacement component has been identified as Hyundai part number 93400-S1750. I consider this a significant safety concern because the failure prevents me from reliably signaling my intention to turn or change lanes to other motorists. The malfunction occurs during normal operation of the vehicle and creates the risk that surrounding drivers will not know that I intend to turn or change lanes. The vehicle currently has approximately 86,611 miles. I reported the issue to Hyundai Motor America and requested assistance because this is a safety-critical component. Hyundai declined my request because the vehicle is outside the warranty period. I am submitting this complaint because I believe the premature failure of a component necessary for the reliable operation of the vehicle's turn signals may constitute a safety-related defect, and I am requesting that NHTSA document and evaluate this failure.

We have been involved with an Oil Consumption problem since 2025 maybe earlier. No leaks just an over use of oil. I have had to fill it myself or take it to the dealer. They did testing and di some kind of cleaning that took 8 hours. We still have the problem and while driving the whole car shut down. No power in the middle of a highway. This has now happened twice and the first time we had to call AAA for help. It showed an engine sign and we checked the code. First it was an small air leak but they didn't find anything. It came up again, same message so we replaced the gas cap, but the oil was still disappearing and the car had shut down again. I spoke with the Hyundai corporation and they said to do the combustion cleaning again. So we set it up but found out that we had to pay for it so we declined. They refused to do anything about the car. We later found there were other cars made by the same company with the same problem. I did some research and they have had an Oil Consumption problem for quite a while. Now the Catalytic Converter is showing up as having problems. Well that's where the oil goes and can shut down the car due to airflow. They never disclosed it to us face to face, we had to find out about it after the the warranty was up. That was very dangerous to have stopped on a highway.

ENGINE, FUEL/PROPULSION SYSTEM, POWER TRAIN
Complete unmitigated loss of acceleration and power while traveling at highway speeds, creating an immediate life-threatening road hazard. Following a warranty engine replacement and mandatory dealer software flash at Clay Cooley Hyundai (Sherman, TX), the vehicle began experiencing powertrain communication issues. While operating the vehicle at 65 MPH on the highway, the vehicle completely failed to accelerate and lost propulsion power, nearly resulting in a catastrophic rear-end collision with an oncoming 18-wheeler semi-truck. Dealership diagnostics claim "no trouble codes present," but live data telemetry confirms the High-Pressure Fuel Pump (HPFP) is actively commanding and delivering a dangerous 1,600 PSI to the fuel rail at hot idle. This abnormal fuel delivery is paired with a severe powertrain stutter in 3rd gear. Service personnel at multiple locations confirm a widespread, high volume of transmission failures and severe drivability issues specifically tied to this recent Hyundai software update. Corporate has denied repair coverage. The vehicle remains an active highway safety hazard and is completely undrivable.

Subject: Formal Dispute: Warranty Breach and Failure to Repair – 2023 Hyundai Santa Fe Timeline & Facts:11/2/25 (~52,000 miles): I officially reported an intermittent loss of power and severe engine revving (up to 7,000 RPM). This created a severe safety hazard when merging and accelerating from an idle stop.3/28/26 (Under 60k miles): After months of diagnostic delays, Hyundai confirmed the Dual-Clutch Transmission (DCT) needed replacement under the 60,000-mile warranty. A Hyundai Case Manager tracked the issue.Service Delay: Hyundai delayed repairs due to a lack of loaner vehicles, which were grounded for recall updates. Commuting pushed my mileage to 60,218. The Case Manager assured me coverage was locked in because the defect was documented before 60,000 miles.4/8/26: Due to corporate protocol, they ordered a valve body installation instead of a new transmission.8/11/26: The valve body failed. Hyundai delaership resubmitted the transmission replacement request. Corporate denied 100% coverage because the odometer was now over 60,000 miles (60,218). They are offering only 80%, leaving me with a $1,000 plus out-of-pocket expense.Legal & Contractual Position:Hyundai is contractually and legally obligated to cover 100% of this replacement. Under federal and state consumer protection laws, any defect reported prior to warranty expiration must be fully repaired by the manufacturer, even if the final repair occurs after the mileage threshold. The current mileage is a direct result of Hyundai’s internal diagnostic and loaner delays.Demanded Resolution:I demand that Hyundai cover 100% of the transmission replacement costs immediately. I am hoping this escalation to the NHTSA will help in bringing this matter to a positive end result, otherwise I have no choice but to pursue formal legal remedies.

ELECTRICAL SYSTEM
The horn has now stopped working in my vehicle twice. It was replaced 01/27/2023, and is now non-functional again. I believe this to be a safety issue as I have no way to warn other drivers or pedestrians of my presence, if necessary. One example of this, was that a vehicle was proceeding into my lane on the interstate yesterday afternoon and I had to avoid them hitting my vehicle by driving onto the shoulder of the road, as I could not use my horn to let them know they were coming into my lane while I was on the side of them.

LANE DEPARTURE: ASSIST, LANE DEPARTURE: WARNING
The Driver Attention Warning system activates a "coffee break" alert repeatedly after approximately two hours of continuous driving, regardless of actual driver attentiveness. There is no way to permanently dismiss or disable this alert. When attempting to cover the cabin camera to stop the alerts, the vehicle triggers a separate "Limited Assistance" warning that is equally intrusive. There is no scenario where the driver is free from one alert or the other during extended drives. This has created dangerous situations. I drive frequently through mountain roads with sharp curves, steep grades, and limited shoulders. On multiple occasions these alerts have diverted my attention from the road at critical moments and I have nearly been involved in accidents as a direct result. A system designed for safety is actively making driving less safe by forcing interaction with dashboard warnings instead of focusing on the road. The component is available for inspection. The system is functioning as programmed, which is the core problem. It is not a mechanical failure but a design issue that creates a real safety hazard for anyone driving longer than two hours. The problem has not been taken to a dealer as it appears to be functioning as Hyundai intended. The vehicle has not been inspected by the manufacturer, police, or insurance representatives for this issue. No prior warning lamps or symptoms preceded this. Alerts began as soon as I started making drives exceeding two hours. The problem is fully reproducible on any drive of that length.

POWER TRAIN, FUEL/PROPULSION SYSTEM
On XXX, at approximately 6:30 PM, my wife was driving our 2025 Hyundai Santa Fe Hybrid on [XXX] when the vehicle suddenly lost propulsion power. It would not accelerate past approximately 55 mph. With the accelerator pedal pressed fully to the floor, the vehicle did not gain speed. I drove the vehicle myself the same day, immediately after she arrived home, to verify the problem, and I reproduced the identical condition. The vehicle accelerates normally from a stop, but at approximately 40 to 50 mph it stops accelerating and will not exceed approximately 50 to 55 mph regardless of accelerator input. No warning lamps illuminated and no messages appeared on the instrument cluster before, during, or after either event. The vehicle health check in the official Hyundai application reports the vehicle status as normal. The driver receives no indication that anything is wrong. This is a serious safety hazard. Sudden inability to accelerate in traffic creates a substantial risk of a rear-end collision and makes it dangerous to merge onto a highway, pass, or clear an intersection. Because there is no warning, the driver cannot anticipate it. The vehicle has approximately 13,741 miles and was purchased new on XXX. Scheduled maintenance was performed at the selling dealer on XXX at 7,924 miles. The vehicle has not been driven since XXX and is available for inspection on request. It is scheduled for dealer inspection on XXX. The problem has not yet been reproduced or confirmed by a dealer. I am aware of numerous owner reports of a similar loss-of-power condition in 2025 Santa Fe Hybrid vehicles in which the gasoline engine reportedly fails to engage and the vehicle operates on hybrid battery power alone. In several of those reports the trouble code cleared itself before the dealer inspected the vehicle. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

POWER TRAIN, FUEL/PROPULSION SYSTEM, UNKNOWN OR OTHER
This complaint concerns a serious, unresolved powertrain/propulsion safety defect in my 2023 Hyundai Santa Fe. While traveling approximately 70 mph, the vehicle suddenly lost propulsion and would not accelerate normally while surrounded by highway traffic.MOST IMPORTANTLY, THERE WAS NO WARNING OR ADVANCE INDICATION. No warning lights, messages, or symptoms appeared before the loss of propulsion. I had no opportunity to anticipate the failure or prepare to safely exit traffic. This placed me and other motorists at immediate risk of a serious or potentially fatal collision.A Hyundai dealership inspected the vehicle and documented DTC P284001, Shift Fork D Position Fault. Despite this documented fault, the underlying safety issue remains unresolved. Hyundai has not identified a permanent correction or established that the vehicle is safe to operate.There has not been another incident because I will not risk another sudden loss of propulsion by driving the vehicle. The absence of another failure does NOT mean the problem is resolved. The vehicle remains available for inspection.I have repeatedly sought assistance from Hyundai and the dealership without a meaningful resolution. Newer information regarding a possible computer reset/relearn procedure has also been presented, but the dealership refuses to perform it.I reviewed NHTSA complaints for 2023 Santa Fe vehicles and found multiple reports describing similar safety symptoms, including sudden loss of propulsion, inability to accelerate, abnormal transmission shifting, and loss of speed. This raises serious concern that this may not be an isolated failure.A vehicle that can unexpectedly lose propulsion at highway speed WITHOUT ANY WARNING creates an extreme crash risk. I respectfully request that NHTSA review the similar complaints, investigate whether a broader transmission/powertrain safety defect exists, and determine whether corrective action is necessary before this results in serious injury or death.

The 2017 Hyundai Santa Fe was brought to dealership on 3/27/26 for an oil change and a computer update was completed for Emissions Improvement. Upon picking the vehicle up after service, it was noticeable that it was not shifting correctly. I spoke to the service department and asked if the memory was cleared with the update an if it was having to relearn how I drive and the said it should not be affected. This went on for a few days and I left the car with them to duplicate as there were3 no stored codes. After a few weeks, the Teck Line recommended a new transmission, which Hyundai offered goodwill assistance. As we were waiting for the transmission to arrive from being on backorder, a bulletin for Service Campaign 9C2 was release on 5/18/26 that described my experience with shifting issue almost exactly. The transmission was replaced and the drivability issues still persist. Hyundai says that I must let my car warm up for 1-3 minutes to allow a catalyst to reach temperature and not cause rough shifting. This rough shifting is the effect of the update and thus te reason that my transmission needed to be replaced. Further investigation showed that this update is a known issue and cannot be reversed once installed. Currently, I must start my car in 90 degree weather to warm it up as a result of this update which is not logical in any thought process. I have asked Hyundai to cover the balance of the new transmission as this is a result of thier faulty software update with no success.

AIR BAGS
I request that NHTSA review what I believe is a misleading Hyundai warranty extension involving the Occupant Classification System (OCS/ODS), part of the air bag system. Around Mid May 2026, my air bag warning light began illuminating intermittently. I waited because I needed to save up the cash. Around June 2026, Hyundai mailed me a Warranty Extension Notice stating that if the air bag warning light came on, I should take the vehicle and the letter to a Hyundai dealer. The notice contains no exclusions or limitations. I was excited because my local repair shop said it would cost $800 to $2000 depending on the issue. Relying on Hyundai's written instructions, I took my vehicle to the dealer. I was told my repair not covered under the scope of the warranty and was charged over $900. I paid under protest because I felt it was a safety risk to continue driving with an air bag warning. Although my initial goal was to receive a full refund, my main concern is that owners may rely on Hyundai's notice, only to discover the repair is denied. Some may delay repairing an air bag system because of the unexpected cost, creating a potential safety risk. I have written Hyundai July 2026 requesting a full explanation as to why my repair was excluded or a full refund but to date I have not received a response. I ask NHTSA to review whether Hyundai's warranty notice adequately discloses its actual coverage and limitations. I have attached the warranty letter, which contains no exclusions, and my repair invoice.

Hyundai Sante Fe Hybrid 2025 has a bad factory seal on the high voltage harness - hybrid battery connector that causes water to intrude the connector under normal conditions which can short the battery and pose a major safety issue. Hyundai is refusing warranty coverage of my shorted hybrid battery on my brand new 2025 Hyundai Sante Fe Hybrid stating “Flood” with no evidence of flood damage. My car experienced multiple P engine hybrid system faults on XXX and would not drive. I had it towed the Van Hyundai Carrollton on that date. They did not look at the car for over a week and it sat on their lot the entire time. On XXX they finally inspected it and claimed the car had been “flooded” and shorted the hybrid battery. The only evidence they provided was moisture in the high voltage harness. There were no water/silt lines, any other damage to any other components, and no evidence of any water anywhere else on the vehicle. The video they showed of the undercarriage only showed normal splash marks from driving. The car was never flooded/submerged. Any water/moisture found in the harness would have been due to a faulty/defective factory seal that should be impervious to water under normal operating conditions. No water/flooding/submersion damage would have been obvious of this. The dealership refused to provide any evidence and had no follow-up. One key aspect they refused to acknowledge was there was a massive rainstorm in [XXX] onXXX which was also the only rainstorm in the area in the previous 1-2 months. This happened while the car was on the dealer’s lot. The car had no issues with any water prior to being at Van Hyundai. A case was opened with Hyundai Corporate and the Dealship also lied stating the car wasn’t in their system until XXX, which is false as I have phone records, tow records, and appointments showing the 7/10 date, so corporate overlooked that. I disagreed with the dealerships diagnosis as it was a scapegoat finding putting all blame o INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT

A Hyundai recall 9C2 update was applied to my vehicle. Ever since that update my vehicle hard shifts on cold starts which I fear is damaging the transmission. Hyundai dealer was able to replicate this and keeps advising us that concern is ‘under review with Hyundai’. I have the service order that states this. This problem has been ongoing for Months! I think Hyundai needs to find a resolution to this as my research indicates it is impacting a lot of customers.
