2025 Hyundai Santa Fe Owner Complaints

My 2025 Hyundai Santa Fe experienced a sudden rear passenger-side suspension failure while driving under normal conditions. I was driving straight when I heard a loud bang. The vehicle immediately became unable to continue driving. The rear passenger-side wheel was visibly tilted inward at the top. There was no collision, pothole impact, or other known incident that caused the failure. The vehicle was purchased new and has fewer than 30,000 miles. The dealership has presented an approximately $11,000 repair estimate and indicated that the failure is not covered under warranty. I am concerned about the safety and reliability of the vehicle’s rear suspension system and request that this incident be documented and investigated for a possible component defect or safety issue.

The contact owns a 2025 Hyundai Santa Fe. The contact stated that while driving approximately 65-70 MPH, the vehicle shut off. The contact pulled over to the side of the road and restarted the vehicle. During an oil change appointment, the dealer informed the contact of Hyundai TSB Number: 25-01-028H-1 (Seat Heater Unit Software Update) and associated the bulletin with the failure. The dealer completed the repair; however, the failure persisted. The contact stated that the failure identified in the TSB had caused the battery to drain. The vehicle was taken to the dealer, where the HPCU and main wiring harness were replaced twice, the battery was replaced once, and the transmission was replaced once; however, the failure persisted. The contact stated that while driving approximately 20-25 MPH and coming to a stop on an incline, the vehicle shut off. Several messages, including "HEV Low Battery - Hibernation Mode", were displayed. The contact stated that the vehicle failed to restart. The vehicle was shifted into neutral and rolled into a nearby parking lot. The vehicle was towed to the dealer, where the contact was informed that the vehicle was repaired. The manufacturer was notified of the failure by phone and email, and a case was filed. The failure mileage was 23,489.

I am filing a safety complaint regarding my 2025 Hyundai Santa Fe Hybrid, which I purchased as a Certified Pre-Owned vehicle in April 2026 with approximately 15,000 miles. The vehicle currently has approximately 27,000 miles. While driving on the [XXX], my vehicle suddenly and unexpectedly lost propulsion. The vehicle’s electrical systems remained on, but it would no longer accelerate normally. There were no warning lights, messages, or alerts before the loss of power. I was in active freeway traffic with numerous vehicles behind me. Because my vehicle could no longer maintain speed or accelerate, I was placed in an extremely dangerous situation. I feared being struck from behind by another vehicle. It was a terrifying experience. I was eventually able to pull over to the side of the freeway. I turned the vehicle off and waited briefly before restarting it. I was then able to get off the freeway and reach a gas station. Once at the gas station, multiple warning lights illuminated on the dashboard, and I observed that the hybrid battery was not charging. The vehicle ultimately became undrivable. The vehicle was towed to Centennial Hyundai in [XXX] for diagnosis. The dealership advised that diagnosis could take approximately two to three days. This is the first time the vehicle has experienced this failure. However, the sudden loss of propulsion without any prior warning created a serious risk of a rear-end collision. I am concerned that this failure could happen to other Hyundai Santa Fe Hybrid owners while driving at freeway speeds. I am requesting that NHTSA review this incident as a potential vehicle safety defect, including the sudden loss of propulsion, lack of advance warning, and apparent hybrid charging-system malfunction. At the time of this complaint, the cause of the failure has not yet been confirmed by the dealership. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

My 2025 Hyundai Santa Fe Hybrid has multiple ongoing problems. Several are intermittent. BRAKES: The brake pedal intermittently sticks when I first start the car. STARTING/ELECTRICAL: On two occasions the vehicle would not start and roadside assistance had to come to start it. It is also sometimes hard to start. The Digital Key on my phone intermittently fails to unlock the doors or start the car. On occasion, all audio is lost at startup, including the radio, speakers, and turn signal sound. The front left speaker intermittently cuts out or sounds distorted. The passenger front door exterior handle/unlock intermittently fails. The driver side temperature knob is stuck at 77 degrees F. POWER TRAIN: The vehicle hesitates/stutters during the first half mile of driving after starting. SEATS: The driver seat memory intermittently fails to move to the saved position when the car starts. SUSPENSION: A creaking, spring-like noise occurs when the car rocks during initial acceleration and braking, possibly from the driver side front. I have reported this to the dealer twice before. Inspection: I have reported these problems to Westlake Hyundai in Thousand Oaks, CA, on previous visits and have another service appointment scheduled. The vehicle has not been inspected by the manufacturer, police, or insurance. I am concerned about the brake pedal and no-start problems as safety issues.

On three occasions while Highway Driving Assist / Smart Cruise Control was engaged, my 2025 Hyundai Santa Fe Hybrid did not slow down for the vehicle ahead and continued at its set speed. I had to brake manually to avoid a collision. Dates and conditions: UNKNOWN exact dates. All three occurred within the past several weeks. Warning lamps or messages: UNKNOWN. I did not notice a warning before the system failed to slow down. Inspection: The vehicle has not yet been inspected for this problem. I have reported it to Westlake Hyundai in Thousand Oaks, CA, and it has a service appointment scheduled. It has not been inspected by the manufacturer, police, or insurance. The vehicle also has other ongoing issues, including the brake pedal sticking at startup, two no-start events requiring roadside assistance, and intermittent electrical problems. I am concerned this is a safety defect that could cause a rear-end collision.

2025 Hyundai Santa Fe - The sound for the blinkers, rear-view camera alerts, and radio sounds has gone out 2 times, once in XXX and then on XXX. This is a safety issue. I have had issues with an electrical battery drain with the key fob antenna being one of issues draining the battery and replaced in XXX. After the sound went out on XXX, I did not drive the vehicle for 1 day, then went to get into the vehicle on Wednesday, XXX and the vehicle was dead. No lights were on, it would not unlock. I missed the scheduled service appointment I had on the XXX due to the dead battery. The car had sat unused for less than 24 hours. I had to call Hyundai roadside assistance for them to jump the car off and tow it to the dealership yesterday afternoon. The battery drain started happening at 700 miles on the car, where I jumped it off myself, and continued to happen every month or two. I kept jumping it off and taking it to the dealership to let them know what was going on. Sometimes, they would investigate it, and sometimes nothing would get done about it. I have had to jump this vehicle off myself at least 6 times since XXX. Yesterday, I just called roadside assistance. There is clearly an electrical drain on the car battery somewhere in this vehicle. XXX, the car was located in [XXX] on a vacation and started having shuttering and engine light came on. This was fixed on XXX by replacing #4 fuel injector prior to 30,000 miles. This is not a reliable vehicle, or safe. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

with not warming the vehicle would not start using the standard FOB. It would not be recognized. Fortunately, we had an alternative Digital Card (which is NOT standard equipment) that allowed us to start and drive the vehicle. Upon calling Hyundai support we were instructed to take the vehicle to the nearest Hyundai dealership for diagnosis. The diagnosis was a failed BDC (Body Domain Controller). This part took a week to arrive at the dealership and subsequent repairs were made. The dealership indicated that they had seen this problem before, but no service advisories from Hyundai were available for this issue. I have asked Hyundai for an explanation and nothing has been forthcoming. My primary issue with this problem is that if I had not acquired a digital card, at an additional cost of approximately $200, we would have been stranded, with no manner in which to start or drive the vehicle. There were no indications of a problem, no alerts in car, and no alerts via the My Hyundai web site via the internal diagnostics. The BDC just failed, with no explanation. Without any type of explanation or diagnostic information, who knows if or when this could occur again, and where.

the ongoing safety defect affecting my leased 2025 Hyundai Santa Fe. This summarizes the facts as discussed, the danger this defect presents, and the urgent need for resolution. Summary of the Defect Since leasing the vehicle, it has intermittently and without warning decelerated to a complete stop (0 MPH) while driving, regardless of the speed at which I am traveling — including at approximately 30 MPH on local roads and at approximately 65 MPH on I-95. The specific facts of this defect are as follows: The vehicle decelerates to a full stop within approximately 5-10 seconds of the malfunction beginning, with no advance warning. After the vehicle stops, attempting to accelerate again takes approximately 30-45 seconds before the vehicle begins to move, and it does so only slowly. When this occurs, the vehicle beeps and a flashing green “OFF LIMITS” light appears. No check engine light or other diagnostic warning is triggered at any point. This has occurred approximately 25 times since I leased the vehicle. On the last three occasions I reported this, Hyundai/dealership personnel drove the vehicle and were unable to duplicate the problem. As I have repeatedly explained, the defect occurs intermittently and unpredictably, so this is not evidence the problem does not exist. The Danger This Defect Presents I want to be direct about the severity of this situation. A vehicle that decelerates to a complete stop without warning — whether on a local road or on a highway at 65 MPH — creates an immediate risk of a rear-end collision, a multi-vehicle accident, or worse. The fact that the vehicle then takes 30-45 seconds to regain even slow movement compounds this danger, particularly in moving traffic. This is not a comfort or inconvenience issue; it is a significant, stressful, and potentially deadly safety defect, both for me and for any passengers in my vehicle, as well as for other drivers on the road.

The vehicle repeatedly loses motive power while being driven at highway speed. It slows even with the accelerator pressed to the floor, does not shift into higher gears, and drops to 40 to 50 mph. On [XXX], the vehicle lost power at highway speed while I was driving. I had to stop on the shoulder of the hwy. The vehicle could not be driven and was towed to the dealer. The dealer opened R.O. No. [XXX] on 9-3, recording mileage in of 23,595. It inspected the vehicle and confirmed the concern. It replaced the fuel rail pressure sensor (Part No. 35342-2M400) under warranty, confirmed a good idle with no codes, and performed a test drive of about three miles. The dealer reported the vehicle ready on 9-15-26; mileage out 23,596. On [XXX], within a few miles of picking up the vehicle after the first repair, the malfunction indicator lamp illuminated. We returned the vehicle to the dealer the same day; the dealer recorded the mileage in as 23,602. The MyHyundai app shows active Diagnostic Trouble Code P00BD00 (Mass or Volume Air Flow "A" Circuit Range/Performance — Air Flow Too High), powertrain system, recorded at 23,600 miles, with a listed date of [XXX]. The dealer returned the vehicle on [XXX]. On [XXX], four days after the 2nd repair, we brought the vehicle back to the dealer. We reported that it was idling high, at about 1,200 to 1,900 RPM while stopped, and that we had heard a low clicking sound since the repair. The dealer did not keep the vehicle. The next morning, [XXX], about 7 miles from home, the vehicle lost power on a bridge on [XXX]. It slowed to about 50 miles per hour and did not appear to shift. I stopped on the bridge with my [XXX] daughter in the car. VDOT responded. My husband and I switched cars. [XXX] then drove the vehicle. After about two miles it again lost power, and he had to leave the highway and use secondary roads at low speed to get to the dealer. The car is currently at the dealership.

On XXX Bloomington dealer emailed me, take elsewhere 2nd option. [XXX] drove our car and four other cars. All of them vibrate. he really did research. The other dealer did not. He documented everything shared it with the case manager at Hyundai. At least six trips to have this looked out. cannot figure out why it vibrates. Hyundai sent me an email .XXX “Based on these findings, the dealership determined that the condition is consistent with the operating characteristics of like vehicles and does not indicate a warrantable defect or malfunction. The dealership has completed all applicable diagnostic procedures outlined by Hyundai and has confirmed that your vehicle is operating as designed.

NHTSA Vehicle Safety Complaint My 2025 Hyundai Santa Fe has a recurring problem when starting the vehicle. When I start the vehicle, the engine jumps abnormally. I have taken the vehicle to a Hyundai dealership multiple times specifically because of this problem. The condition continues to occur, but I have repeatedly been told that the dealership cannot find anything wrong and that they have to wait for a diagnostic code to appear before they can determine the cause. The vehicle has now developed an additional symptom. When I turn the vehicle off, it sometimes makes an abnormal prolonged gurgling/squeaking-type noise that continues for approximately 3-4 seconds. This shutdown noise is new and is occurring in addition to the recurring engine jumping during startup. No cause has been identified or repaired despite multiple dealership visits. I am concerned that an unidentified engine/powertrain problem is continuing and appears to be developing additional symptoms while I continue operating the vehicle. The vehicle remains available for inspection. I have also experienced problems with both middle-row seats not properly retracting/folding. I reported the problem to the dealership, but only one side was addressed. A component from the back of one seat has also detached. The detached component and vehicle remain available for inspection. I am reporting these conditions because they have continued despite repeated attempts to obtain diagnosis and repair. I do not know the underlying cause, and the dealership has not identified one. Its becoming worse then before so something is wrong.

Pirelli Scorpion 255/45 R20 I am filing this complaint regarding a serious and unacceptable defect with my Pirelli tires. To date, two of the four tires have proven to be defective. In both instances, the defect was not readily apparent while the tires were mounted on the vehicle. The problem was discovered only when a qualified tire technician attempted to remove the tires from their rims. In both cases, the tire structure collapsed during removal. This is extremely concerning. A tire should not collapse or fail structurally simply because a trained tire technician is removing it from the wheel. The fact that this has now occurred with two out of four tires strongly suggests that this is not an isolated incident. I have also researched complaints filed with the National Highway Traffic Safety Administration (NHTSA) and have found numerous complaints involving Pirelli tires and sidewall failures, including sidewall bulges, blowouts, tread separation, and other structural failures. My research indicates that there are at least 15 complaints specifically involving the sidewall giving way. NHTSA states that consumer complaints are used to identify potential safety-defect trends. There are also recent NHTSA complaints involving Pirelli tires reporting sidewall bulges and failures, including complaints involving relatively new tires. Given that 50% of my four tires have now exhibited a serious structural failure, I am extremely concerned about the safety and reliability of the remaining two tires. I do not believe I should be expected to continue using tires that may contain the same defect. I am requesting that Pirelli: Immediately investigate all four tires, including the two that have already failed. Provide a written explanation as to why these tires collapsed during professional removal from the rims. Determine whether this represents a manufacturing or structural defect. Replace all four tires at no cost to me, rather than requiring me to wait for additional

ON 3 separate occasions the vehicle has suddenly quit going.twice going through an intersection after taking off. the third time going up hill near my house. the car would only go 10 mph. A message would come up on the dash that reads " transmission system error, Check transmission oil immediately. That was not the problem. The Hyundai dealership performed a recall update on the computer the first time.but that didn't solve the problem as a week later the same thing happened .Again the car was towed to the dealership. this time another transmission service was performed according to a tech line information. after retrieving my car from the dealership I drove it for less than a week and the same thing happened. The car was towed back to the dealership again.Now the dealership says they can't do any repairs as the computer will not store any malfunction codes so they will know what to repair. I have been in contact with Hyundai Motor America and a case file has been established. " 43176412 ". Hyundai will not accept any responsibility for placing a computer in a car that will not retain a MIL code. Hyundai now tells me they have done all they can and for me to get my car from the dealership and drive it. That is ridiculous. Hyundai wants me to put myself in danger of having a wreck because the car loses power in front of traffic behind me. People start slamming on brakes to keep from hitting me and blowing their horns.I'm also afraid of some loose cannon out there having road rage at me because I can't get out of the way. As for the car and Hyundai , no mention of the shortcomings of the computer was mentioned until the 3rd time the car was towed back to the dealership. Also, there is some type of serious problem with the transmission which Hyundai is failing to be concerned with . This is a dangerous situation. do I need to be seriously injured or worse before Hyundai addresses this issue ?

I am reporting a potential safety defect involving repeated windshield chipping and cracking on my 2025 Hyundai Santa Fe. The vehicle was purchased new. The first incident occurred on April 15, 2025, approximately three months after I purchased the vehicle. While driving approximately 60 mph on a highway in clear, dry conditions with no gravel or unusual road conditions, a small rock struck the upper-right portion of the windshield. The windshield cracked from the impact. The windshield was subsequently replaced on June 6, 2025. In June 2026, while again driving approximately 60 mph on a highway under clear and dry conditions, a small rock struck the center of the windshield and caused a chip. In July 2026, approximately one month later, another small pebble struck the upper-middle portion of the windshield and caused another chip. There were no crashes, sudden braking, turning maneuvers, or unusual driving conditions involved in these incidents. I am concerned because the windshield has repeatedly chipped or cracked from relatively small rocks or pebbles. I have owned and driven other vehicles for many years and have never experienced this level of repeated windshield damage from minor road debris. The windshield was supplied by Hyundai. I believe the repeated failures warrant investigation into the quality, durability, material, manufacturing, or specifications of the windshield glass used in this vehicle. The windshield is an important safety component, and a chip can potentially develop into a larger crack and impair the windshield's integrity while the vehicle is being driven. I have photographs of the most recent chip and an invoice documenting the windshield replacement performed on June 6, 2025. I am requesting that NHTSA review this complaint and determine whether similar complaints exist and whether a safety-related defect or trend may be present in the 2025 Hyundai Santa Fe.

While operating the vehicle, the vehicle suddenly began severely hesitating and stalling. During the incident, engine RPM surged to approximately 6,000 RPM and accelerator pedal response became abnormal. The vehicle was not responding normally to accelerator input, which significantly affected the ability to operate the vehicle safely. The vehicle subsequently recorded diagnostic trouble code P0304 – Cylinder 4 Misfire Detected. The abnormal operation of the vehicle during the incident was also captured on video. The vehicle was taken to an authorized Hyundai dealership for diagnosis. The dealership has advised that because the condition is not currently occurring and they have been unable to duplicate the problem, they may be unable to diagnose or repair the vehicle. The safety concern is not simply an illuminated check-engine light or a stored P0304 code. The concern is the combination of severe hesitation/stalling, abnormal accelerator response, and the engine surging to approximately 6,000 RPM while the vehicle was being driven. The cause of the condition has not been identified and, at the time of this complaint, the vehicle has not been repaired for the underlying problem. I am concerned that this condition could recur without warning while accelerating, entering or crossing traffic, or traveling at highway speeds. A recurrence could result in an inability to accelerate normally, unexpected vehicle behavior, loss of normal vehicle operation, or a collision. Hyundai has been notified of the issue and I have requested further technical investigation of the engine misfire as well as the transmission/TCU and electronic throttle/accelerator systems due to the high-RPM event and abnormal accelerator response. I am submitting this complaint because this appears to be a potentially serious safety-related defect and I want NHTSA to have a record of the incident and determine whether similar stalling, high-RPM, acceleration, transmission, or engine-misfire.

Multiple occasions of the ADAS lane centering system operating unsafely. The worst one was on a gentle left-hand curve on a concrete surfaced bridge at night. The system allowed the vehicle to slowly drift to the outside of the lane. When it was fairly close to the white line, it jerked the wheel back to the left and then released the steering to my control while pointed hard into the oncoming lane. It will do similarly during the day when approaching a center turn lane on the highway. Sometimes it will decide that it should be in the turn lane, will make a rapid input, and then return control to me, now pointed at the oncoming lane. When the vehicle returns control to me, it indicates it by making the steering wheel and lines in the HUD grey, no chime, no warning icon, just green to grey and release the wheel in whatever direction it's pointing. It also sometimes slows drastically for vehicles that have exited the highway when on cruise control or applies hard braking for vehicles in the other lane while in a curve on a hill. There are no lights or malfunction warnings and the vehicle self-diagnostic says everything is operating correctly.

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.

What component or system failed or malfunctioned, and is it available for inspection upon request? The vehicle suffers from an intermittent, total engine stalling and propulsion failure. Without warning, the engine completely shuts down while driving and automatically drops the vehicle into "Accessory (ACC) Mode". The vehicle is fully intact, operational when it restarts, and is available for immediate inspection upon request How was your safety or the safety of others put at risk? This issue has occurred five total times in live traffic, severely risking the safety of the vehicle's occupants and surrounding drivers. The most recent and dangerous incident occurred on the freeway in heavy, stop-and-go traffic. A sudden, complete loss of power on a high-speed freeway leaves the vehicle entirely vulnerable to rear-end collisions, as it leaves no room or momentum to safely coast to the shoulder. Has the problem been reproduced or confirmed by a dealer or independent service center? No. The vehicle has been brought to an authorized Hyundai dealership five separate times specifically to diagnose this exact stalling issue. Because the failure is intermittent, dealership service technicians have been unable to replicate the problem during their test drives or resolve the root cause. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? The vehicle has been inspected five separate times by authorized Hyundai dealership technicians during the service appointments mentioned above. No police, insurance, or independent manufacturer representatives have inspected the vehicle yet, as the stalling has not yet resulted in a physical crash. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear?There are absolutely no dashboard warning lights, check engine indicators, error messages, or mechanical symptoms prior to the failures.
