2024 Hyundai Santa Fe electrical problems

Filed Nov 9, 2026 · Driver assistance, Electrical · TX

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.

My 2024 Santa Fe has completely lost electrical power three times in under five months: XXX. Each time it was found dead in my driveway. In XXX and XXX, the day before it died, the radio, turn-signal sounds, cameras and alerts lost all sound. The third time there was no warning. Roadside assistance was called all three times. In XXX, the roadside technician jump-started it and his tester showed a bad battery, so I left it running and drove it straight to the dealer. In August and October it had to be towed. The first failure came the day after recall work on the rear-view camera harness (recall 288). The dealer's tests said the battery passed in XXX and XXXX, and no part was replaced. On XXX the dealer said the battery "finally tested bad" and replaced it under warranty. The cause of the drain has not been identified. While driving, the car has also at times sputtered and then come back to life. All three failures happened at home, but a car that loses all power without warning can leave a driver stranded or stall in traffic. The second failure came two weeks after we returned from a long highway trip from [XXX] to [XXX]. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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.

It seems like the computer or electrical system is failing in the main ECU and the entertainment console. The car's entertainment console will blink when driving over a bump or while braking. It will disconnect from apple carplay and won't reconnect. More importantly, it will turn the car completely off while braking sometimes. This happens while moving. There was an incident where the car didn't wake up and unlock with the key fob first thing in the morning. I had to unlock it with the physical key. Once I opened the door th car woke up and the alarm went off.

2024 Hyundai Santa Fe gasoline model. My VIN was included in Hyundai Safety Recall 263 / the federal safety agency Recall 24V‑529 involving the Transmission Control Unit and potential damage to the dual-clutch transmission. On September 25, 2024, at fewer than 5,000 miles, the transmission failed and the vehicle was taken to a Hyundai dealership. The transmission repair/replacement was approved and the vehicle remained out of service until October 21, 2024. On June 5, 2026, the vehicle would not start and required towing to an authorized Hyundai dealership. The vehicle has remained at the dealership continuously since June 5 and has not been returned to me. The dealer has undertaken multiple unsuccessful repair/diagnostic efforts during the current visit. I am currently being told that the condition involves the engine/powertrain. Hyundai is now sending an engineer to the dealership because the condition remains unresolved. I am reporting this history because this vehicle experienced a transmission failure shortly after being subject to a federal transmission-related safety recall and has now developed another major engine/powertrain condition while still relatively new.

With my 2024 Hyundai Santa Fe SEL, at Cold start the coolant gage on the digital cluster always shows 2-3 bars on the gauge and once the vehicle is put into drive (at least 30-45 seconds start up), the coolant gauze immediately increases in temperature reading without full drive (15 feet after gear placed in Drive). This may be improperly reading the coolant temperature and the OEM thermostat may be defective from manufacturer build. This can cause improper cooling and increase engine failure due to overheating.

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
