2024 Hyundai Santa Fe 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.

Unknown source causing carbon monoxide to go into the cab of vehicle. This causes the occupants, especially those in the passenger seat, to feel symptoms of CO poisoning. Have used multiple air monitors and a carbon monoxide monitor which have shown as much as 983 ppm in the vehicle while driving. I have taken my vehicle to multiple Hyundai dealerships and an exhaust shop in my town and they can not find an issue but it continues to happen. It began from when I first got my car in December of 2025 and still continues t this day.

Every winter since we got my 2024 Santa Fe, the car shakes violently at highway speeds in very cold weather. It started the first winter we had it (2024-2025) and was worse in the winter of 2025-2026, when the shaking was uncontrollable at times. It feels like the wheels are loose and about to come off. The closest comparison is a tire that has blown out and is flapping hard against the road: the whole car shakes uncontrollably while I try to slow down. It would not stop, so I had to keep driving the car like that for long periods because I had no other vehicle. The date entered is approximate (winter 2025-2026). My daughters were often in the car. This is in addition to other unresolved problems with the same vehicle: three total electrical failures, failure to accelerate from a stop, self-braking with nothing in the road, rolling after being shifted into Park, and driver-assistance malfunctions in bad weather. Another owner's complaint on a 2025 Santa Fe describes the same vibration that gets worse in the cold and cites Hyundai bulletin 25-SS-002H-1, so I would like to know whether that bulletin applies to my vehicle.

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.

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 Santa Fe has rolled after I shifted it into Park, on more than one occasion. One time I clearly remember was in my own driveway, a few months ago (around August 2026). Other times have been sporadic, and I did not record the dates. The date entered is approximate. This is the same condition addressed by recall 24V‑529 (Hyundai campaign 263). the federal safety agency VIN lookup shows no open recall on my vehicle, and the Hyundai app shows no open or completed campaigns at all, even though other recalls were performed in June 2026. So I cannot tell whether 24V‑529 applies to my car or was performed. I have asked the dealer for my full recall history. Until this is resolved, I set the parking brake every time I park.

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.

Since delivery in XXX my 2024 Santa Fe 2.5T AWD often fails to accelerate from a stop. When I press the gas, there is a delay before it engages, like a slipping clutch, and on inclines it rolls backward before it catches. It happens most in the first few minutes after the car is started or restarted, when stopped on a slope, and it seemed worse in hot weather. On XXX, I was pulling out of a gas station onto a very busy highway in [XXX] right after refueling. I waited for a larger gap so our older daughters, driving behind us, could pull out at the same time. When I pressed the pedal, the car moved only a few feet, just enough to put us into the road, and stopped. I floored it again and the car still did not move. Oncoming vehicles in both directions, traveling about 50 mph, had to slam on their brakes, nearly causing the traffic behind them to collide, but they avoided hitting us broadside. My husband and our two youngest daughters were in the car with me. I mentioned the failure to accelerate and the lag at several earlier service appointments, but it was never written up or looked at. Those visits usually took only 15 to 20 minutes. On XXX, when I picked the car up after a week-long repair for other problems, I asked the service counter to log this complaint. They had already printed my paperwork and told me to bring it up next time. The car has been back in the shop since XXX, and the technician has not been able to duplicate the problem so far.

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.
