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)

For approximately the past year, my 2021 Hyundai Santa Fe, currently with about 23,000 miles, has experienced intermittent engine and fuel-system problems. During start-up, the vehicle sometimes makes an abnormal rattling/cranking noise, followed by noticeable engine and vehicle vibration. Warning lights may appear, and on some occasions the engine does not start successfully on the first attempt. When it does start, it may initially run rough. The vehicle has also stalled intermittently and has had repeated incidents where pressing the accelerator produced little to no engine response or acceleration. This creates a serious safety concern because the vehicle may unexpectedly stall, lose power, or fail to accelerate when needed while driving. The vehicle has been at an authorized Hyundai dealership for more than one month. The dealership has been working with Hyundai Tech Line and has replaced or evaluated the low-pressure fuel pump, high-pressure fuel injector, high-pressure fuel pump, MPI/port fuel injector, and valve cover. The latest recommendation is to drain, clean, and refill the fuel tank. Despite these repair attempts, the root cause has not been clearly identified or permanently resolved. I am concerned that the repair process has become trial and error, with additional components being replaced while the underlying safety-related issue remains unresolved. I am also being asked to pay out-of-pocket for some of these unsuccessful repair attempts. The vehicle is currently at the Hyundai dealership and is available for inspection if needed.

The vehicle is experience severe, progressive engine oil consumption, completely depleting its engine oil below the safe operating limit ("Low" mark on the dipstick) every 500 miles. This creates an imminent risk of sudden engine seizure, catastrophic mechanical failure, and sudden stalling at highway speeds. The authorized dealers (Safford Hyundai Manassas) and corporate case management (Case #43193472) have failed to fix the issue after multiple visits. Furthermore, dealership service staff explicitly instructed me that I must continue operating the vehicle for an additional 1000 miles even if the oil falls below the safe "Low" limit to satisfy corporate test parameters. Forcing a consumer to drive a vehicle with depleted engine oil is a severe safety hazard to myself and other drivers on the road. The manufacturer is also underreporting oil consumption volumes on service invoices to avoid warranty repairs.

I bought my 2023 Hyundai Santa Fe at Auto Fair Hyundai in [XXX] in XXX new. This is my third Hyundai from this location over the years. I have always serviced it there ever since I bought it. ( oil changes, tire rotation etc.) Back in XXX while driving home from [XXX] to [XXX] on [XXX] I hit the brakes in the left hand lane, in traffic and my vehicle shut off and wouldn’t restart. Very scary luckily a young man helped push my car off the highway. I sat 5 minutes or so and it restarted. I was told to disable the start/ stop feature which I did. On XXX I went back to auto fair in [XXX] with my issue. I was told I needed a new battery there was corrosion $408. I had them clean the corrosion $95 and I’d bring the vehicle to my mechanic friend where my battery was tested and it was good. I was told to disable the start/stop feature. I went out XXX and forgot to disable the feature and I stalled at 4 way intersection. Stuck there people beeping, traffic backing up and drivers passing by running red lights very frustrated. Yesterday I called Auto Fair service department (on a recorded line) asking if this is an ongoing issue with this make/model. Is there a recall? I was told they haven’t heard about this issue at all and she said good luck. I have 5 year warranty and there is only 24,000 miles on my vehicle. I found a forum online with many others with Hyundais having this issue. This is an accident waiting to happen I’m also reporting it to Hyundai Corporate and Highway safety commission.

At times the engine will freeze up, stall the car while driving, or the car will altogether turn off when at a stop sign or light, while the car is still on. I've had the oil changed before the mileage indicated expired because the engine light came on and I was told the car had no oil at all when I know the oil was just changed within a 3 months time frame.

The vehicle experienced a sudden, intermittent engine stall while driving, specifically when slowing down or coasting to a stop in live traffic. When the engine dies, the vehicle immediately loses engine power, power steering, and power braking assist, creating an extreme safety hazard. After stalling, the vehicle refuses to restart for several minutes. An authorized Hyundai dealership previously replaced the high-pressure fuel pump under warranty to address this issue, but the dangerous stalling has persisted over the last 2,000 miles. The vehicle continues to randomly shut off without throwing a permanent check engine light or diagnostic trouble code, and the manufacturer has failed to correct this critical safety defect.

The car started having problems immediately after replacement with a new battery. The issue with the ISG (Idle Stop and GO System) started appearing. When the Auto Stop Indicator turns green, the car stalls which puts my life at risk. I have spoken to a number of mechanics and I am not getting a satisfactory answer on how to fix this problem.. One mechanic told me it was the starter which turned out not to be true. I have also spoken with a number of other mechanics and they are clueless on how this problem can be remedied. And the Hyundai dealter wanted $275 just to look at it but with no guarentee. The whole issue is putting my life and other motorists at risk.
