2025 Hyundai Santa FE problems

POWER TRAIN

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 ?

TIRES

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

Chest Clip, Buckle, Harness

While driving, the chest clip fell apart into multiple little pieces. I was not aware until we were parked at our destination and I went to remove my child from the seat. I am unaware how long he did not have a chest clip for during the duration of the ride. It also broke apart into pieces small enough for my child to choke on. I have reached out to the company.

VISIBILITY/WIPER

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.

POWER TRAIN

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.

Auto had a very strong gas smell after arriving at work. Check the engine and underneath the car for leaks but no fluids on the ground or my garage. Smell persisted while out of town and made appointment for inspection. The dealer service man said it was suffering numerous leaks and we’re awaiting parts. Latest info was still leaks present and would advise after making certain no leaks persist.

STEERING

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.

POWER TRAIN

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

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.

TIRES

235/60R18 103H While driving the 1year old car, the tire pressure reading in the vehicle began to go down, upon exiting the vehicle it was determined that two holes blew through in the side wall of the tire. Thankfully, this was not as dangerous of a situation as it could’ve been as the car had just come off the highway and was traveling at a lower speed a residential neighborhood. The tire is not available, it was disposed at the place it was replaced at. There were no major tire stores open as it was a Sunday so it replacement tire had to be purchased from a local tire vendor.

FORWARD COLLISION AVOIDANCE: WARNINGS

I am submitting a second and more urgent safety complaint regarding the Driver Monitoring and Driver Assistance systems in my vehicle. I previously reported this same core defect: the system falsely fails to recognize my face, sounds repeated warnings, and disables driving assistance while the vehicle is moving. Despite that prior complaint, the defect remains, and the seriousness of the danger has clearly not been recognized or addressed. This defect has now placed my life in immediate danger. While I was driving, the system falsely determined that it could not properly see my face. It sounded repeated warnings and then abruptly disabled driving assistance. That sudden withdrawal of assistance created a near-crash situation. I was attentive and was not experiencing a medical emergency. The danger was created by the system’s false detection and defective response. A safety system should reduce danger. This system detected a supposed problem and made the situation more dangerous by removing the assistance that was helping keep the vehicle under control. Had this occurred beside a concrete barrier, near stopped traffic, in a construction zone, on a curve, or next to a large truck, the result could have been a fatal collision. I could have been killed because of this system defect. When a driver cannot be verified, the vehicle should maintain lane control, reduce speed, activate hazard warnings, and perform a controlled safe stop. It should never abruptly withdraw assistance and create a more dangerous condition. I request that NHTSA investigate why a previously reported life-threatening defect remains unresolved and require Hyundai to correct this system logic before someone is seriously injured or killed.
