2025 Hyundai Santa Fe Hybrid

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.

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

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 NHTSA Hotline for assistance. The failure mileage was 13,000.
