2024 Hyundai Santa Fe driver assistance problems

1. What component or system failed or malfunctioned, and is it available for inspection upon request? • The factory digital A/V audio amplifier failed due to an internal electrical short circuit. It is physically located on the driver's side behind the 3rd-row side panel trim. Yes, the component is still inside the vehicle and is available for inspection upon request. 2. How was your safety or the safety of others put at risk? • The failure completely disables the vehicle's audio output, leaving it 100% silent. This cuts off all audible warning chimes for critical safety features—including Forward Collision-Avoidance Assist, Blind-Spot Collision Warnings, Rear Cross-Traffic Alerts, and Parking Sensors. Driving without audible crash-avoidance alerts significantly increases the risk of an accident. Additionally, the internal short creates an active parasitic battery drain that can unexpectedly stall or strand the vehicle in dangerous situations. 3. Has the problem been reproduced or confirmed by a dealer or independent service center? • Yes. The problem was officially reproduced, diagnosed, and confirmed by AutoNation Hyundai [XXX] on XXX under Repair Order #XXX. 4. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? • Yes, the vehicle and component were formally inspected by a factory-trained Hyundai dealership technician ([XXX], Technician ID XXX). 5. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? • The primary symptom was a severe, unexplained parasitic battery drain that first appeared and completely destroyed the battery in XXX. The battery had to be replaced under warranty at that time. The complete loss of cabin sound and safety chimes occurred suddenly on XXX, caused by the amplifier shorting out and continuously draining the electrical system.

Since delivery in May 2024, the driver-assistance systems on my 2024 Santa Fe malfunction in rain and snow at highway speeds, around 65 mph. The cameras report being blocked and a cascade of alerts goes off: warnings to put my hands on the wheel when they already are, "take a break" driver-attention warnings, and "conditions not met" messages. Smart cruise control shuts off without warning, and lane assist loses the lines. About two months ago (around September 2026), driving in pouring rain, the car flashed a message that it was shutting down while I was on the road. The date entered is approximate. The driver-attention camera also gives constant false warnings in normal driving: when wearing sunglasses, with an arm resting on top of the steering wheel, or with dust on the camera. Both drivers in our household experience this. Sudden alarms and systems shutting off at highway speed in bad weather are distracting and dangerous. I reported this in writing to the dealer in February 2025, saying the safety features had nearly caused numerous accidents, especially in bad weather. The dealer offered to show me how to turn the features off, but that never happened, and nothing has been repaired. My daughters were usually in the car when these events happened.

On 10/19/2026 at about 7:03 AM, driving about 50 mph on a rural two-lane road, with no vehicles, pedestrians, stop signs or lights nearby, my 2024 Santa Fe suddenly braked hard on its own. The electronic parking brake and Auto Hold engaged, and the car sounded a series of alarms and showed a warning screen I had never seen before. It was not the normal forward collision warning. My two daughters were in the car on the way to school. I photographed the dashboard right after, once the car was moving again. It showed 4 active warnings plus driver-assistance warning lights. It was a cold, foggy morning, about 42 degrees F. I have reported this to the dealer and asked them to pull the stored codes and driver-assistance logs. The car is at the dealer now for repeated electrical failures and a failure to accelerate from a stop.

My 2024 Hyundai Santa Fe Calligraphy was purchased in February 2026 with about 12,000 miles on it. The previous owner had problems with the backup camera and had returned it to the dealership. When I bought it, I was assured that the camera issues had been fixed. It worked fine for a few months, then I started getting a green screen with "no signal" message when I tried to go into reverse about 75% of the time in May of 2026. I took it to the dealership and they could not get the problem to duplicate. They ran a basic diagnostics test on it and said everything was fine. I picked up the vehicle and it started malfunctioning again, so I took it back. I alerted the service department driver what was going on with it and asked him to see if he could duplicate the problem while I spoke with the advisor. The driver was able to get it to duplicate the green screen. The service department replaced a cluster unit (it is under warranty) and returned the vehicle to me. It worked fine until early October, and then the green screen issue occurred again. The screen also began flickering at times when I put it in drive. I made an appointment to come in and have it looked at but they said if it was working on the day I came in that they would not be able to do anything, as it had to throw a code. A few days before my appointment I was backing up in a parking lot and the reverse camera screen wasn't working. Another vehicle was backing up at the same time and I was unable to see them (they didn't see me either) and my collision warning did not work, either. We collided and my vehicle was dented badly on the lift gate. I took the vehicle back to Hyundai and they found a coaxial cable that was loose, tightened it, and it worked for 3 days. Now it's not working again and I still have damage to the rear-end of my car from the parking lot accident.

Multiple warnings flashing across dashboard regarding lane assist and emergency stopping. The Auto Hold came on by itself and turned orange. The emergency parking brake came on and stayed on. The warnings kept dinging every 30 seconds while driving and lit up every icon on the dashboard. Once parked I turned off lane assist, but it continued to trigger warnings. Lights flickered in park and with engine turned off. There is a clear malfunction going on somewhere.

I have had the vehicle in 4 times for check forward attendition warning system light keeps coming on. The first time they replaced the front camera. The situation came back after I was using the cruise control on a express way. Did not do it do it on the road but as soon as you stopped and turned the vehicle off the vehicle check forward attention warning system would come on and off and the only way to shut it off was to stop from more than 20 minutes and it would reset. Took the vehicle back 3 times and they could replicate so there was nothing they could do. The issue came back today. The check forward attention warning system light keeps going on and off. We stopped and let the vehicle sit and upon restarting the check forward attention did not reset . This time the vehicle lost all volume from the dash board. You could recieve phone but no volume. No radio volume. All the safety features that Bing are not working. Check the set up and the volume had a red 🔺️ next to the volume. 4 times into the shop for the same issur

Hyundai - DAW - Driver Attention Warning / Forward Attention Warning System This issue warrants immediate consideration for a recall. Despite wearing glasses, sunglasses, or no glasses, the problem persists. I occasional do remove my glasses while driving, and the warning continues to sound. This occurs regardless of the time of day, weather conditions, or whether I am sitting upright or reclining. The warning randomly activates and deactivates, sometimes without any intervention. Occasionally, I simply allow the warning to sound without taking any action, and it remains active for a few seconds or until it triggers a warning that the system will be turned off, at which point it deactivates. I have attempted various troubleshooting methods, such as keeping my eyes open, adjusting my seating position, wearing and removing my glasses, and tilting them to minimize glare. None of these methods have proven effective in preventing the warning from activating or in making it deactivate. This is a persistent problem. Hyundai dealerships initially informed me that the warning might be an annoyance and their response was to simply refrain from using it. However, if a basic feature like cruise control in a 2024 & 2025 model is rendered unusable due to a design flaw (which this certainly is), it constitutes a clear violation of safety standards and should be addressed through a recall. The incessant alerts are highly disruptive and can be quite frustrating. For instance, driving with an arm in the 12 o’clock position triggers a warning, while wearing polarized sunglasses also results in an alert. The presence of a setting to disable the warning is a welcome feature, but the system’s persistent alerts can be overwhelming. The alerts continue even after taking a break. It is distracting and a safety hazard. Drivers should be able to adjust the sensitivity of the feature to turn off this feature. Currently, there is no way to disable or temporarily disable this feature.
