2025 HYUNDAI SANTA FE Electrical System Problems

My car was locked and battery had died. I was able to get in car with key from fob. I had to put car charger on battery in order to start car. This car is a year old with 18,531 miles

I am submitting this complaint to formally report ongoing and unresolved vehicle safety defects involving a leased 2025 Hyundai Santa Fe. These defects include persistent toxic or chemical odors inside the passenger cabin, electrical and body control system malfunctions, and unintended vehicle operations that present serious risks to occupant health, vehicle security, and public safety. Despite multiple service visits and repeated requests, Hyundai dealerships have refused or failed to conduct comprehensive diagnostic testing, leaving the vehicle in an unsafe and unreliable condition.

There have been several times that I have been driving and either turning onto a 4-lane road (2 lanes going each way) or driving on the parkway, where my car has slammed on the brakes by itself. Not only was I not prepared for this to happen, but neither were the cars behind me. I tend to drive with at least 1.5 car-length space between myself and the car in front of me. Last week, I was making a right hand turn (going north) into the right lane from a residential street. The only other car near me was the one driving in the left lane (also going north). My car drove about 100 ft and maybe realized that there was a car next to me and just slammed on the brakes. I was suddenly thrown forward. My seat belt locked and I was thrown back into my seat. I had a bruise from my seat belt and came too close to slamming my head on my steering wheel. Thankfully, the car behind wasn't tailgating. About a month ago, I was driving on the parkway going east. I was originally in the right lane. I put on my blinker and when it was clear, I changed lanes to the middle lane. After I was clear and my blinker was off, my car started screaming to tell me that there was a car in my driver's blind spot (this happens EVERY time I switch lanes). I drove for maybe 1.5 - 2 miles and then suddenly, my car slammed on the brakes. Someone must be watching over me because the Escalade behind me (definitely tailgating) was somehow able to swerve into the left lane and then swerve around me to cut me off in revenge. They were screaming and honking at me, while I was screaming and yelling at my car. They could have easily have plowed into me (we were driving at least 60mph) and could have caused a horrible accident that could have killed myself or others around me. I have notified Hyundai of this issue and have read many similar complaints online. Hyundai claims they cannot "replicate the situation" and therefore, Hyundai Corp is unable to fix the problem.

On more than 10 occasions the SUV gets stuck in neutral upon starting the car. You can only switch between Park and neutral and are unable to drive the car. It will not go into drive or reverse. Sometimes this problem lasts for 10 minutes. The car will not shut off during that time even when you press the stop button the screen just resets. The only solution is to wait or to press the hard reset button on the computer screen. It is a dangerous situation because if you need to go somewhere, you physically cannot drive the car. I took it to the car dealership when the car was almost brand new and they had it for eight days and they did a software update but I don’t think they found the problem. this problem is now having more and more frequently.

My 2025 Hyundai Santa Fe Hybrid with 1724 miles was unresponsive in the garage. Not able to get in the car because the 12v battery was completely drained. Hyundai dispatched a tow truck to take it to the local Hyundai dealership. A service provider did call me to let me know the car was there. He also told me that apparently this problem I had was a known issue with the 2025 Santa Fe Hybrids. I had no advance warning of any imminent problems with the battery.

Battery/Electrical: 3 separate occasions the battery drained completely overnight, requiring mechanical key to open and jumpstart services from AAA (covered under Hyundai services). Risk of leaving me stranded on isolated areas. Problem confirmed via 3 requests for AAA to jumpstart my vehicle. Hyundai service dept inspected vehicle, confirmed low battery levels, unable to reproduce issues overnight, reported no electrical or mechanical issues that would cause battery drain. No warning messages, lamps, or symptoms prior to each failure. Steering wheel column has friction squeak when using driver assist and adjusting direction. No issues at this time.

The contact owns a 2025 Hyundai Santa FE. The contact stated that while parked and seated in the vehicle, the instrument panel was blinking on and off several times before going dark. The contact stated that the infotainment system also displayed a blank screen. A dealer was contacted. The vehicle was taken to the dealer for a recall repair, and the contact was informed that there was no failure with the instrument panel. The vehicle was not repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 6,000.

I’ve had several instances where putting the vehicle into park the system doesn’t register the shifter button being pressed and continues to be in the current gear. IThis seems to be a safety issue since it has happened multiple times ever since I bought the vehicle. I made sure to fully press the Park button but it continues to stay in the drive or reverse gear The first time it happened I did not notice the vehicle did not register the gear change and the car started to roll forward towards a building.

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 contact owns a 2025 Hyundai Santa Fe. The contact stated that while driving at various speeds and taking her eyes off the road ahead, there was a warning chime and a red warning light illuminated, advising the driver to "Consider taking a Break". The contact stated that the safety feature is the Driver Monitoring: Camera/Sensor and the safety feature was activating while turning her head or moving her eyes from looking ahead. The contact stated that the chime was loud and was distracting while driving. The contact stated that the failure was almost constant. The contact called a local dealer and was advised that the system could not be deactivated. The dealer referred the contact to the NHTSA Hotline to report the issue. The manufacturer was not informed of the failure. The failure mileage was approximately 700.

Vehicle fails to appropriately recognize when it is put in Park. The dash shows a "P" indicating the vehicle is in park, but emits a continuous beeping sound with a message on the dash that reads, "Auto Stop is Off. Shift to P or N and start engine manually." However, when pressing "P" as it states I must do, it then reads, "Gear already selected," before returning to the previous message. This is all while a "P" is illuminated and beeping is continuous. Throughout this time, if the brake is released, the car begins driving forward as though it is in Drive, not Park. I have 3 separate videos of this happening.To answer the above questions: The vehicle has repeatedly been inspected by a Hyundai dealership and each time I am told the issue cannot be replicated. I am happy to have it inspected again. It most certainly puts my safety and others at risk as it continues driving after I have engaged park. No police or insurance representatives have yet inspected it. No others warnings or messages appear before it occurs, only during. The issue first started just before 5k miles on the car and has since occurred at least 5 more times.
