I am reporting a serious and recurring safety defect with my 2023 Hyundai Santa Fe hybrid, purchased new in January 2024. The vehicle has suffered from over 30–40 sudden hybrid system failures, including loss of acceleration, “stop vehicle” warnings, and check engine lights. These incidents happen without warning, including while driving at legal speeds (40–70 mph), on residential streets and highways. Most recently, the car failed twice in two days, while my teenage son was driving within all road laws, including once with a friend in the car. The vehicle simply stopped accelerating in the middle of traffic, endangering them and everyone around them. These failures have happened at legal speeds ranging from 40–70 mph, on both residential roads and highways. There is no advance warning, just abrupt loss of power and sudden warning messages. We’ve taken the vehicle to the south charlotte Hyundai dealership multiple times. Each time, they either reset the check engine light or replaced indicators: but never addressed the root hybrid system failure. We filed a lemon law case, and Hyundai responded with only a $2,000 offer including legal fees, requiring us to keep the dangerous vehicle. We rejected the offer. These failures have occurred with children and passengers in the car. We have documented as many incidents as we could, including photos, service records, and communication with Hyundai. The vehicle is available for inspection upon request. I no longer feel safe driving or allowing my family to drive this car. This is a critical hybrid system failure that continues to place lives at risk. I believe this may be part of a wider pattern affecting Hyundai hybrid vehicles, and I am pleading with the NHTSA to open an investigation before someone is seriously injured or worse.

The horns stopped working, and this is a safety item since it’s the only way to notify another vehicle or pedestrian if they will be hit by my car. Another day, a car came out of the parking lot and almost hit my car. I was only able to avoid that accident because I reversed quickly. I took my car to the dealership, and it was confirmed that the horns are not working. To fix this issue, I need to replace them. But since my car is out of warranty, I will need to pay for this service. On 07/14/2025, I called Hyundai (case number 4117-7538) to request the application of an extended warranty that they started to offer for the 2021-2025 model year elantra (z03). Since my car is the 2022 model year Santa Fe, they did not accept my request. I noticed that on several websites, Hyundai car owners are complaining about their car horns. Just the fact that Hyundai started to provide an extended warranty for a different model, but in the same year range as my car, confirms that they are having issues with this part. I just know about this extended warranty because I also have an 2024 elantra hybrid, that is covered by it (as you can see on the uploaded letter).

The car horn stopped working very suddenly, without any prior warning, while I was driving. The car has around 36000 miles on it, so the horn dying out was a surprise. Driving without a functioning horn has also become a safety issue. I have an upcoming appointment with the dealership to diagnose and fix the problem.

I tried to open the doors of my locked vehicle with the key fob and there was no response. I tried several times and nothing happened. I called aaa and they opened the door with my valet key and was able to pop the trunk. He checked the battery and it was working fine. He then noticed that the wire connecting the battery to the fuse box has melted at the point of contract with the fuse box and actually melted part of the plastic fuse box. There was nothing he could do, so I had to have the car towed to the dealer. I was lucky that the total meltdown of the electrical system did not occur when I was driving or I would not have been able to see any of the controls on the inside of the auto and not be able to use the gear shift to put the car in park.

I am reporting a critical safety defect involving my brand-new 2025 Hyundai Santa Fe. While driving on the freeway, the vehicle experienced a complete brake system failure, nearly causing a serious accident. My boyfriend was driving at the time, and when he tried to brake, the vehicle did not stop. He had to take immediate evasive action to avoid crashing, which put both of us — and nearby drivers — in immediate danger. The vehicle was purchased about a month ago and had never been serviced or modified. After the failure, it was towed to hanlees auto mall Hyundai in richmond, California, where the service department inspected it and confirmed the problem was caused by a missing clamp, which is a critical component of the braking system. This appears to be a manufacturing or dealership oversight. They took photos, documented the issue, and made the repair — but they also told me they cannot guarantee this won’t happen again. There were no warning lights, messages, or symptoms before the failure — the brakes simply stopped working during operation on the freeway. As of now: •the issue has been confirmed by hanlees Hyundai in richmond. •I have not yet received a loaner vehicle. •the car is currently in my possession, but I do not feel safe driving it. •I have been in contact with supervisor steve at Hyundai of vacaville, who has offered to pick up the vehicle and provide a loaner, but that has not yet occurred. This is an extremely dangerous failure that occurred on a brand-new vehicle. I am requesting a formal investigation into this issue to determine if it’s isolated or part of a broader manufacturing defect with the 2025 Hyundai Santa Fe. A missing brake component that results in total failure at freeway speeds is a life-threatening safety hazard and should be taken seriously by the manufacturer and federal safety officials.

The oil pressure switch has a faulty seal causing oil to leak out onto the engine block. This causes oil on the underbody and ground, smoke amd smell from oil on got surfaces, knocking noises from the engine, reduced power or hesitation, illumination or the check engine light and oil pressure light, high speed stall, and will also cause fire in the engine compartment resulting in death or sever injury. I have taken my car to the red mccombs Hyundai dealership in san antonio TX for repair and they have confirmed that it is the oil pressure switch seal that failed. The oil leak has also damaged electrical components causing a malfunction in the dash cluster and steering wheel control.

I've been having a few issues with my 2025 calligraphy hybrid I bought in November related to the main screen, sometimes when I start the vehicle it doesn't properly initialize and it will show me some of the icons and nothing else. No hud, no speedometer, no remaining fuel, no hybrid information. It's a huge safety issue, it seems to happen every couple of weeks. I thought it was the digital key not working properly so I disabled that but still having issues. I have to let the car sit for a few hours or overnight and then when I turn it on then it's back to normal. I realized that when the main screen is off, it doesn't capture the mileage so the mileage is off by close to 300 miles right now. Huge issue, I've had it happen on my way home from work (25 miles) at least 4 times, and once on a road trip (150 miles). Also when this happens because I can't see the speedometer, I have to use waze on the infotainment screen (which works without issue) to see my actual speed because the built-in navigation only shows me increments of 10 mph on the screen (this is just stupid).

Hello, to whom this may concern, the abs light turned on the dashboard on a Tuesday evening. My wife kept driving. In the next couple of days, it would feel like the car was all over the road, under braking. It seemed very hard to take off. On Friday, I was outside and heard the car was making a noise. As an automotive technician, I knew the abs module was cycling nonstop. I pulled the fuse out of the fuse panel to make sure it wouldn't catch fire. We took the car back to the dealer when the bulletin came out for these cars catching fire due to an abs issue years ago. I went to the dealer on that Saturday and informed them of the abs module cycling nonstop. They told me that the bulletin had been done already and there was nothing they could do for me. I called Hyundai customer support, and they forced me to pay a diagnostic charge of $220 to tell me it was a failure internally in the abs module and that they wouldn't cover the repairs. I found it very surprising that Hyundai only had to change a fuse to prevent cars from catching fire. It doesn't make sense to me how the NHTSA allowed them to only change a fuse and not the module that Hyundai said was faulty. This puts every car that I drive next to in danger, with the module going off nonstop while I drive down the road. This has all happened in the last month. Please hold Hyundai truly accountable for this nonsense. It is unacceptable that they can get away with just changing a fuse to prevent a fire, and not fix the actual issue, the abs module. Thank you,.

As we were driving down the interstate we began to see smoke coming out our vents and after a few seconds saw flames coming from the passenger side of car. We quickly tried to pull over but brakes weren’t working. Safely pulled into grass median. Luckily we were able to quickly exit through the driver door. After about 30 seconds the car was engulfed in flames.

I bought this vehicle at enterprise car sales back in March 2nd 2019 and it's been having issues for a while now recall after recall I bought this vehicle at 7745 indiana avenue riverside California 92504 I actually bought this vehicle without realizing that this car had a recall prior to buying it off the lot therefore in California law this company should have not sold the vehicle with a recall as Hyundai has warned me about this as he advised they cannot sell a vehicle with a recall on it. When I had to google search my recall as I have not received a letter enterprise car sales gained the letter for the recall prior to my buy and did not mention anything as this recall was sent out on the letter way prior to buying ever since buying this vehicle I have had numerous recalls as to now there is a gdi issue with the engines as I have made many complaints through the financing company santander consumer USA, Hyundai, enterprise car sales, and it seems like no one has listened to me on the lemon I have gained as I'm sure it sounds just like a complaining customer. I pay a very high interest rate and very high monthly payments 523 a month is expensive let alone expensive to pay for a vehicle that I constantly have to put in maintenance and now my engine is gone my VIN number somehow is not on regards to the recall but yet my VIN number has been on every recall Hyundai has ever given out when it comes to my vehicle as the gdi 3. 3 l should be really considered on regards to a recall as well as the 2. 4. I'm not very happy as I would like to have a voice on to what is fair I am sick of this vehicle having issues after issues as I do take care of my vehicles with good maintenance routine all I can ask for is to have someone here my voice and to take action either from enterprise car sales to Hyundai which I believe enterprise car sales is more reliable at this point than Hyundai since Hyundai let me be aware of the California law they cannot sell a vehicle with recall.

I was on a semi residential-commercial street that turns on to a freeway entrance. I was turning right and unavoidably entered the freeway when the sudden loss of power occurred. The car slowed down to about 20 mph and pressing on the gas medal didn't yield any more power. I immediately pulled over to the emergency lane upon entering freeway to let fast moving vehicles pass me on the left side. I turned off the vehicle and turned it back on. It seemed to turn on as normal so I proceeded to drive home slowly, staying on the slow right lane of the freeway driving under the speed limit until I took my exit to get to my home. All seemed ok until I turned onto residential street near my home. Again the car slowed down suddenly to 20mph and giving it more gas did not make a difference. The time difference between the first and second (recorded) incident was 25 minutes apart, having driven the vehicle only 140 total miles. The dashboard flashed a 20mph speed limit even though I never set those parameters, didn't set cruise control, and I didn't have auto stop or hold buttons engaged. The car simply slowed down to a 20mph speed limit without my input to the vehicle settings.

Car was unused for less than a week and upon going to use it the vehicle was dead. Jumped vehicle and next day was dead again. In researching the problem, many other Santa Fe hybrid owners have run into this same issue. Dealership admitted many hybrids from Hyundai face this issue and recommended installing a trickle charger for when not using the vehicle for a couple days which seems ridiculous for a brand new vehicle. Likely something draining battery slowly in car.

Stopped for gas, vehicle started but would not go into gear, engine lights indicated 'check hybrid system', warning lights shown. 1/2 hr on the phone with dealership to assist. No problem detected when returning to home dealer. Second episode occurred, vehicle at dealer for the past 4 weeks. Episode repeated at dealership yet "no abnormalities are detected with diagnostics ".

Vehicle killed the battery even with new alternator and new battery. Dealership does not know why and it died while at the shop. Vehicle has extremely high oil consumption and light comes on every once in a while. Vehicle started shaking and took to two dealership. Vehicle was diagnosed with a burnt valve in cylinder one. Dealer stated they have not heard of this problem. Called Hyundai representative corporate and was told they never had this problem before and have not heard of it. Out of warranty and was informed I would have to pay for it even though it is common in these vehicles.

Frequent intermittent dash warning lights, no speed indicated, no tach indicated, cycles through warnings of safety systems malfunctioning. No lane departure, no adaptive cruise, no cruise, no forward collision warning, no blind spot warning. The disabling of these systems puts all drivers at risk. Dealership replaced front camera and windshield to fix this issue. Not fixed, continues to alarm at random times while driving.

Horn failure, confirmed by Hyundai dealership. No warning or indication of failure. Went to use horn in a safety situation when I needed it, and it was non-functional. A huge safety risk for myself and other drivers on the road. In doing research, this is a known manufacturer defect, with most owners having to replace low and high horns multiple times due to failure. The horn units apparently due to placement and design fill up with water, which leads to failure, again, without warning.

I am reporting an urgent request immediate action regarding a serious unresolved, recurring public safety issue with my vehicle. It is potentially the fault of alexandria Hyundai's service department (in alexandria, va) who had just serviced my vehicle for what should have been a routine servicing (on may 7). My car had a catastrophic and complete failure on a high speed highway (the car quickly decelerated) which represented an incredibly danger situation for myself and other drivers on the road. My car was purchased in 2023 and has 15,241 miles. It has been perfectly maintained. On [xxx], I was returning to my home in virginia from maryland on an 8 lane highway with a 55mph speed limit when I had a very dangerous complete failure of my car. Simultaneously, the car started bucking back, the speed was decelerating regardless of my pressing the accelerator to keep my speed the same as traffic, and I received a flashing large red message that said "check hybrid system - stop safely. " fortunately I was in the far right lane and was able to veer it over to a narrow shoulder. It was 8pm and getting dark. After a short while, the car lost all power so I was on a narrow shoulder with no lights flashing anymore. I was in this dark car with a lot of traffic speeding my with my 2 dogs. I became incredibly stressed about how we were going to get home. I contacted aaa, a police officer and uber pet who worked together in this unsafe situation on the side of the highway to get myself and my dogs home into the uber vehicle with only the front door opening (no power). It was over 2 hours before I was home safely it was incredibly stressful situation. The car was towed to alexandria Hyundai and they dismissed the issue and fixed nothing. I contacted Hyundai customer service and asked for escalation and they have done nothing. I am restricted in my driving because of the severe safety risk but had to drive again on [xxx] and it occurred again on a highway information redacted pursuant to the freedom of information act (foia), 5 u.

The horn has failed and been replaced 2 times after purchasing from brand-new. It has failed again but the vehicle is now out of warranty.

I am writing to express my concern regarding an ongoing and persistent issue with excessive engine oil consumption in my 2015 Hyundai Santa Fe, subject: severe oil consumption issue - 2015 Hyundai Santa Fe - VIN: 5xyzwdla1fg238718 the vehicle consumes an alarming amount of oil, approximately 1 quart every 300 miles. This rate of consumption is far beyond what is considered normal and strongly suggests a serious mechanical or manufacturing defect. I have already taken the vehicle to a mechanic to diagnose and attempt to resolve this problem. Based on their professional advice, the following parts were recently replaced: 1. Engine valve cover gasket 2. Turbo charger oil line 3. Spark plugs unfortunately, despite these repairs, the issue of excessive oil consumption remains unresolved. The rate of oil loss remains consistent and dangerously high. This was first informed by a service center when I took the car for a random check. Then, after traveling 1,000 miles, the engine oil level dropped again. After that, I am keeping an eye on that. This level of oil consumption poses a significant risk to the engine's long-term health and reliability, and it is a major inconvenience and expense for me as the owner. I am deeply concerned that a major engine component may be failing.

I own a 2014 Hyundai Santa Fe sport 2. 0t which has had door latch issues.   recently, the front passenger side door latch needed to be fully replaced due to a failure which caused the door to be loose latching and the latch sensor always showing open.   I paid out-out-pocked for this repair as the Hyundai dealership said there are models which this exact issue was identified, but they said the parts extension had not been placed for my exact vehicle.   they were also confused as to why this was not being covered as they see so many of these same repairs. Now, less than one month later, the front driver's side door is now experiencing lock issues in which a loud grinding noise is occurring when the vehicle attempts to lock or unlock the door.   additionally, the door does not unlock some of the time from the external and the manual door handle on the interior is getting harder and harder to open.   both of these issues are consistent with other recalls for other Hyundai models and consistent with the door latch module and actuator failure.   I would like to file a complaint regarding this issue as it seems to be a common issue with Hyundai models using this door latch module.   I believe the parts extension and repairs for these door latches should be covered by Hyundai especially as this becomes a large safety issue with driving the vehicle with concerns of door latch stability and security.

The car loses power. The battery and key ignition light keep coming on. A message displays auto engine off. Please shift to n or p and start engine manually. After communicating and showing video proof of the incident, the dealership replaced the alternator and battery. The issues started around 5000 miles. The infotainment system lags and the car lags. Sometimes I am left on the road because the case refuses to cut on or off.

Car did dashboard update on 4/10/25. Had less than 4300 miles. Unable to unlock car due to dead battery. Car unlock service opened door for tow company to jump battery and advise that the new 2025 Santa Fe hybrid battery needs to be replaced. May need other service (alternator or hybrid battery too) but the 12v battery had been drained. Interior lights would not turn on prior to this happening.

Loss of acceleration and stuttering when I was trying to get up to speed on the interstate going up a hill. Instantly blinking check engine light. Won't go above 2000rpm or 60mph. P1326 code read glow relay short circuit.

The reverse camera system did not come on when reversing. It could lead to someone like a child getting hurt if they’re walking behind the vehicle. The problem was reproduced by the dealer and serviced for this issue. They confirmed it was the same problem as the recall. There is a recall for 2022 Hyundai Santa Fe’s that were manufactured in the alabama plant. This is where my car was manufactured. For some reason, it was not included in the vins that were recalled.

Vehicle will not change out of ev electric mode and return to gas power causing hybrid battery drains to zero, vehicle loses acceleration, you can push the gas pedal to the floor and you have no acceleration, very unsafe when you are in traffic, no power to maneuver or avoid other vehicles quickly if needed, potential for accidents, hybrid system warning lights and alarms go on, have to try and pull over safely, battery will not recharge or takes a very long time to do so, only recourse is to shut vehicle off and restart which seems to reset vehicle, which in turn does not leave any warning lights other than codes on to show dealer, very dangerous to lose all acceleration capacity while in traffic, this has happened multiple times with the latest being today 3/23/25, vehicle is available for you to inspect, have had other powertrain codes issues as well, dealer has replaced fuel pump and erg valve but it does not resolve this hybrid issue, this battery drain issue has occurred multiple times but no resolution, help!.

My steering would work while I was driving with my kids in the car, my breaks were barely working, the hood started smoking and something under the hood in the engine caught on fire, there was a horrible smell when I was breaking and the breaks would jolt. The engine and cooling was not turning off even with my key taken out, the fan engine was running nonstop no matter what, smoking etc.

The contact owns a 2017 Hyundai Santa Fe. The contact stated that the automatic power door locks failed to operate as needed. Due to the failure, the contact had to manually unlock and lock all doors inside the vehicle. In addition, the contact stated that the button to unlock the gas cap also failed to operate as needed. The vehicle was not yet diagnosed or repaired. Neither the dealer nor the manufacturer were notified of the failure. The failure mileage was approximately 72,000.

12v battery discharges and SUV has to be junp started. Hyundai removed the battery reset button that existed until 2023 model year. Manufacturer should do recall to change the 12v battery charging characteristics for 2024/2025 model years.

12v connector for phone charger melted my phone cord. Reported to centennial Hyundai las vegas and high desert Hyundai kingman az. Both service departments said my vehicle cannot detect the problem because I purchased a substandard plug-in. I have worked as an operator of high voltage electrical systems. I understand in some circumstances that a system cannot detect a fault, however the company is still responsible for the fire it caused. This is unsafe and can cause serious consequences. It must be corrected.

Our vehicle continues to experience loss of power driving , on cold days below freezing. When driving normally this hybrid vehicle will be in hybrid mode at a stop, then when accelerating, the ice engine will not start to assist the hybrid, causing a bare minimum of power to be available, just enough to pull over. On several occasions this has led to very near rear end collisions from the driver's behind. So far I've been able to avoid injury, as I recognize the condition and am hyper attentive to its possible happening. The vehicle handed shown any check engine warnings until yesterday. As it was dying I pumped the accelerator to see if it would go, latching a tps out of range code. The condition has been brought to Hyundai corporate and dealerships with no repair, and no resolution, they say it's fine. This is well documented by others driving Santa Fe hybrids, and tucson hybrids on forums. No one fix has been established, with some dealerships replacing parts, and others no work being done because their scan tool sees nothing. With dozens of recalls for minor inconvenience issues, I do not understand why a recall for this drivability safety issue has not been mandated! these vehicles are defective, and potentially very dangerous. Loss of power, acceleration when others are behind you anticipating you to go, is a real serious danger, not to mention you being stranded in frigid weather. This began happening at 23k miles and continues today with 48k miles on mine. If the vehicle is shut off, then restarted, it is again drivable, until the next happening. One reason Hyundai, says nothing's wrong, and often blames the owners. I can't be without a vehicle, and Hyundai has washed their hands on this, so I'm stuck Hyundai must be forced into an investigation, and a safety recall on this or nothing will be done. How many accidents or deaths are required to get a recall accomplished?.

Every time it rains, one of the dual tone horns will fail. I have had the horn replaced 2 times. I am beginning to have a problem with the horn again after this last rain. It is a matter of time before it fails completely after a rain and becomes unusable. I feel this is a significant warning feature that must be reliable.
