2025 Hyundai Santa Fe driver assistance problems

Filed Oct 30, 2026 · Acceleration, Driver assistance · CA

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)

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 the federal safety agency 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.

I own a 2025 Hyundai Santa Fe that was purchased on 08/15/2025. The first malfunction occurred on 08/25/2025, only days after purchase, and the vehicle has experienced repeated safety-related issues since then. The vehicle has repeatedly displayed false Forward Collision Warning alerts, Blind Spot Warning failures, Park/Neutral errors, and intermittent disabling of safety features. The most serious incident occurred when the vehicle unexpectedly entered “Limit 20 MPH” mode while I was pulling into active traffic with my toddler in the vehicle, limiting acceleration and creating a safety risk. I have also experienced false collision alerts while parked and after the vehicle was shut off. The vehicle has been taken to the dealership multiple times for diagnosis and repair attempts. Some issues were duplicated by dealership personnel, while other visits were documented as “could not duplicate.” A front ultrasonic sensor was replaced, but the vehicle continued experiencing safety-related concerns afterward. During the repair process, I was informed and observed that dealership personnel appeared limited in what repair actions could be taken after consulting Hyundai through their diagnostic system. I was also informed that Hyundai influenced what could be included on service reports and that dealership personnel were instructed to “print the book” rather than fully document observed concerns. I believe this may have affected repair efforts and documentation of ongoing issues. The vehicle has been out of service for extended periods and the issues continue despite repeated repair attempts. Due to the ongoing malfunctions and inconsistent operation of the safety systems, I no longer feel safe driving the vehicle because I am concerned it may not function properly during a real emergency situation. Attached are photos of various dashboard errors and warning messages that occurred during these incidents to document the alerts and malfunctions experienced.

On April 27, 2026, my 2025 Hyundai Santa Fe experienced an intermittent electrical/system malfunction affecting multiple vehicle systems at the same time. Multiple orange warning lights/messages appeared on the dash, including driver-assistance warnings and the master warning triangle. At the same time, the front turn signal stopped working, causing rapid flashing; the power locks stopped working; the windows would not roll up or down; and the rear liftgate would not open using the key fob or exterior liftgate button. The vehicle/component is available for inspection upon request. This created a safety and access issue. The malfunction affected exterior signaling, locks, windows, and rear cargo access. My dog was in a crate in the rear cargo area, and I could not open the liftgate normally to access him. The failure of locks/windows/liftgate could create a serious emergency risk if a person, pet, or cargo needed to be accessed quickly, and the turn signal failure affected my ability to safely signal to other drivers. The issue lasted approximately 30–40 minutes and did not immediately clear after turning the vehicle off and back on. It later returned to normal on its own. This has happened more than once. The vehicle was taken to a Hyundai dealership for inspection. The dealer has been working with Hyundai Techline, but as of now they have not been able to reproduce the issue or find active diagnostic codes. I provided video evidence of the dash warnings from the incident. The dealer advised that scans currently show systems operating as designed because the issue is intermittent and not occurring during inspection. There were no prior symptoms before the failure. The warning lamps and messages appeared at the time the malfunction occurred. Seek reimbursement for rental car fees and diagnostic fee.

The vehicle has two display panels, molded into a single frame. There is an infotainment panel on the right that handles music, maps, and phone interaction. There is an instrument panel on the left. The infotainment panel has not issues. The instrument panel blanks out for 3 - 5 seconds every few minutes, and then reappears. Occasionally the words "No SIgnal" in big red letters will appear. Occasionally the gear selection letter will remain on the otherwise blank screen. The screen also shudders / tears occasionally before blanking. It does this whether the vehicle is moving or parked. I purchased the vehicle used, Jan 2 2026. I noticed the problem a couple of days later. It has continued. It is not getting any worse or any better.

Since I bought the car the forward attention warning goes off constantly. I’ve taken it to the dealership multiple times. They took off my eztag, stated it was blocking my camera. This is not the issue. Now there are 56 cars ahead of mine. This will be the 3rd time for the exact same complaint. It affects everything in the car. My cruise control doesn’t work because of this issue. If you turn the toggle back on it has more warning. Just the beeping constantly is going to cause an accident. I’ve asked Hyundai to buy it back they refuse. This is a known issue.
