2025 Hyundai Santa Fe Hybrid driver assistance problems

Filed Nov 6, 2026 · Driver assistance · MS

I only am entering Automatic Emergency Braking because I have no other section to select. While my wife was driving our 2025 Hyundai Santa Fe Hybrid at a speed of approximately 55 mph the vehicle suddenly, without any type of warning, began slowing down to a speed of 20 mph. A message appeard on the display above the steering "20 mph limit". The vehicle decreased the speed from 55 mph to 20 mph in approximately 5 to 6 seconds. She could not accellerate above 20 mph regardless of how hard she tried. She had no control of the speed. Fortunately she was on a two lane highway with little or no traffic. She stopped the vehicle and put it into Park, waited and began travelling again. It would not go over 20 mph and the message remained on the screen. She managed to get home. When the vehicle was parked, turned off and then turned back on the message was no longer on the screen. I then drove it directly to Hyundai dealership to report the problem. I was told they could do nothing unless they were able to get the vehicle to repeat the issue. I had to leave it at the dealership. I have since read that Hyundai has a "Fail Safe" mode that causes the vehicle to do that if there is an issue with the engine, hybrid mode, transmission or emissions. This issue happens with ablolutely no warning. I just begins to stop. My major complaint is that this could occurr when I am traveling at 70 mph on a major Interstate hwy while in the left lane in high traffice and have no way of maintaining my speed long enough to get to the shoulder of the road. This could easily create a major catastrophe. Hyundai should address this issue ASAP before someone is killed because they have no control of the speed of the vehicle.

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.

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)

The driver assistance warning system continuosly goes into shutdown mode. Eye monitoring system always states that you are not keeping your eyes on the road. I have tried using different glasses or no glasses. Changing the steering wheel settings also seem to have no effect. This is very dangerous as it will start decelerating and stopping in the middle of a freeway in heavy traffic when this warning is activated. This only happens with the lane keeping assistance and adaptive cruise control are on. Hyundai issued Technical service bulletin 25-GI-001H, but they did not solve the problem

Driver attention warning system constantly gives aggravating notices of "suggest take a break" with chiming sound when driving with or without sunglasses or other glasses. I cannot use cruise control. I have tried several different sunglass types with no success. After first warning, goes off every 4 minutes, either cancelling cruise control when I am using it or just causing annoying aggravation which takes my attention off the road. I cannot turn this feature off. It is so aggravating that it draws my attention from the road ahead and impacts my patience while driving. Due to eye condition, I must use sunglasses while driving in sun. Hyundai did not make this limitation clear when I was buying the vehicle, and they refuse to do anything about it now.

My wife was parking our vehicle near the front of our home, simply rolling forward toward the car in front of her to complete parking on the left side of the street when the vehicle unexpectedly accelerated on its own. The vehicle turned hard to the right, struck the bumper of the parked car she was pulling up behind, continued right across the traffic lane where it hit two parked cars on the other side of the street with significant impact, lifting and turning one onto the sidewalk, at which point our vehicle went across the sidewalk and stopped after hitting a fence. The forward collision avoidance that we have experienced engaging previously, never engaged, despite hitting multiple vehicles on the lefft side and then right side of the street. The collision avaoidance alarms that we have experienced sounding previously, also never went off. The airbags never deployed, despite hitting 3 cars at two different sides of the street, as well as an iron fence that never moved. The vehicle went from traveling less than 5 mph while completing the last few feet of parking to a high rate of acceleration within a path of less than 40 feet, as evidenced by the significant damage it left. Had my wife not come to a stop as quickly as she did, she could have been seriously injured. If anyone had been on the sidewalk - there are 3 shcools on this block that children are often present - someone could have been killed. The vehicle is currently at a body shop being evaluated by insurance adjuster and likely a total loss. We reported tot the manufacturer and they intend to repsond to us by 9/16 and inspect the vehicle in its current state.

The contact owns a 2025 Hyundai Santa Fe. The contact stated that while his wife was driving at an undisclosed speed, the Forward Attention Warning (FAW) system activated. Shortly afterward, the message "System Shutting Off" was displayed, and the Automatic Emergency Braking System briefly engaged, jerking the vehicle and dramatically reducing its speed of the vehicle but not to a complete stop. The vehicle returned to normal functionality, but the failure became a regular occurrence. No warning lights were illuminated. The vehicle was taken to the dealer, who determined that the vehicle was functioning as designed but informed the contact that his wife's glasses may be interfering with the Forward Attention Warning (FAW) system's eye detection ability to monitor her eyes. The vehicle was not repaired. The manufacturer was notified of the failure, a case was opened, and the contact was referred to the federal safety agency Hotline for assistance. The failure mileage was 13,000.

The “consider taking a break” warning comes on far too much and has almost made me wreck twice due to being startled.
