2025 Hyundai Santa Fe Hybrid

On 08/22/26 at approximately 11:45 AM I was stopped at a traffic light and struck by a Ford Pickup truck whose approximate speed was 45 mph as described in the police officer who witness the accident totaling my Hyundai 2025 Santa Fe. No airbags were deployed. According to the police officer the frame was bent as well. Please see attached vehicles pictures

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)

The contact owns a 2025 Hyundai Santa Fe. The local dealer was contacted and confirmed that the parts to repair the vehicle under NHTSA Campaign Number 25V808000 (Back Over Prevention) were on backorder. The vehicle was not diagnosed or repaired. The manufacturer was able to confirm that parts were not yet available. The contact had not experienced a failure.

Everything normal when parked in store parking lot. When vehicle was started to leave I noticed the vehicle had no sounds ... no radio sound from any source at any volume setting, no turn signal clicks, no parking proximity beeps, no navigation voice guidance, no sounds at all. All dashboard/visual displays were normal. Parked vehicle in garage when I got home and the next morning the battery was dead. Had to jump start the vehicle (the dead battery "fixed" the sound problem). An AI search shows this is a known issue for the 2024 & 2025 Hyundai Santa Fe and I found AI & You Tube fixes saying to "soft reset" the Infotainment/Sound system by turning the ignition to the "On" position (not starting the vehicle ... foot off the brake and push ignition once, then again). Use a paper clip or pen to press and hold the little dimple reset button just below the right side radio knob until the system resets, then foot on the brake and start the vehicle. If this does not work, disconnect the starting battery's Negative battery cable for 15 minutes. This is a mid level safety issue because audible warning systems will not work. Took the vehicle to the Hyundai dealer we bought it from but they didn't offer any acknowledgement that other same model vehicles have had similar problems and said they could not check or do anything since the vehicle wasn't currently having the problem. I had to argue like hell just to get them to record that the issue had occurred.

1. The SUV experiences complete power loss and goes into limp mode. Have been in nearly 3 accidents on highways with a vehicle that goes from 65 to 35 with no warning and then cannot accelerate or gain speed. 2. Battery, out of no where, goes from 3/4 full to 1 or 2 bars. 3. Extreme shaking of the vehicle while driving and at rest. 4. Vehicle is less than a year old and has been in for the same issue 4x. Currently with dealership since 6 July with no communication despite calls and in-person visits. 5. Loaner not provided despite car being under warranty and brand new.

There are two main causes of concern that have occurred numerous times. The first is a driver attention alert will flash on the screen very frequently, which is very distracting to the driver. It says you should take a break but will come on very frequently right after starting driving and seems to be due to someone squinting their eyes. The second is that when sensors get blocked or dirty it will flash messages about the parking system, not being active while you were driving the vehicle, which is a huge issue and very distracting, especially considering that it’s a parking system that you are not using because you’re actively driving the vehicle. These notifications need to be able to be disabled or should be adjusted to not do this.

Less than 10 month old Santa Fe Calligraphy suddenly started flashing warning signs like Check Drivers Assistance System, Check Headlight LED, Check door assistance system. It comes on randomly, sometimes when the car is running, sometimes when the car is stopped. It flashes these warnings rapidly. When it is going on, the side view cameras stop working. One time when this was happening, I was at a stop light and it automatically went to park. It has happened multiple times so far. I have 2 children ages [XXX] and [XXX] that I drive around with and am concerned about safety. I have taken it to two different service centers at 2 different dealerships based on recommendation from Hyundai and they have not been able to replicate the problem hence they can't find the diagnostics of what is wrong. We have opened a case with Hyundai. The case number is XXX The case manager is [XXX] [XXX] I have taken videos of it whenever it has happened. I am not sure how to upload it as your documentations only allow photos. I am sharing the photos with you. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
