2024 Hyundai Santa Fe Hybrid

I keep getting the alert “Check Forward Attention Warning system”. It’s nonstop even when I’m not driving the vehicle. I have taken it in to the dealership 4 times. This started only after the most recent software update that Hyundai released. The dealership did everything they could, and contacted Hyundai who told them to replace the camera on the steering wheel (which they did). They thought that would fix the problem, and it did not. I believe this is something with the new software update since other users on forums are complaining about this exact alert. It’s sporadic, it happens very frequently though, but it is unpredictable. All of this points to a software update and Hyundai has not fixed this bug in over a year. It’s beyond frustrating that there is no fix and they are just making their customers deal with this issue with no apparent fix.

The vehicle will not accelerate past 30 mph on the highway. The fuel system will not engage, and the vehicle continues to run on hybrid mode which causes the battery to drain and acceleration to throttle. This occurs on all drive modes and fuel conditions.

While driving on the highway the vehicle lost power and then lowered the transmission gear and would not accelerate over 17mph regardless of pressure on accelerator. I switched from auto hybrid mode over to sport mode so the gasoline engine could be used yet the transmission would not increase power to the tires. I stopped several times and restarted with no corrections. Vehicle battery drained quickly and vehicle alarm told me to pull over to charge battery. Sat for a few minutes to charge battery, put in drive and vehicle went forward to 17-20 mph and would not go any faster. Pedal was to the floor. The vehicle then gave several alarm lights and system failures. I limped the car home and called roadside assistance. Tried to put car in reverse for an easy tow and the car wouldn't move in reverse.

The rear power liftgate on my 2024 Hyundai Santa Fe Hybrid (VIN [XXX]) repeatedly opened and closed on its own, without any command from the key fob, interior button, or any occupant. This occurred over a period of several months. It happened while the vehicle was parked and, more dangerously, while the vehicle was in motion at normal driving speeds. An un-commanded liftgate opening while driving creates a serious safety hazard: loss of rear visibility, the risk of unsecured cargo being ejected onto the roadway, and the gate striking a person or object when it deploys unexpectedly. The overnight, un-commanded cycling while parked is extensively documented on my home security cameras, which recorded the gate opening and closing repeatedly throughout the night. The dealer (Williams Hyundai, Lansing, MI) diagnosed the cause as a faulty resistance fault in the rear hatch wiring harness assembly, which sent false signal inputs to the vehicle and triggered the motorized latch and actuators. The repair was completed under the New Vehicle Limited Warranty. A secondary effect of the continuous overnight cycling was repeated deep-discharge of the 12V battery, leaving the vehicle dead on multiple mornings. I am reporting this because the un-commanded operation of a motorized liftgate — particularly while the vehicle is moving — is a safety defect that may not be isolated to my vehicle. I have retained service records, the dealer's diagnostic notes, and the home security footage, and can provide them on request.

While driving on the highway, my 2024 Santa Fe Hybrid suddenly and without warning lost propulsion power. The loss of power was immediately accompanied by multiple simultaneous warning lights across the instrument cluster, glitching and abnormal behavior of the cluster display, and then a complete electrical shutdown of the vehicle. After the shutdown, the vehicle would not restart. The failure occurred in connection with a software update on the vehicle. At the time of the incident the vehicle had approximately 12,828 miles on it. Losing motive power while traveling at highway speed created a serious crash risk, as the vehicle was unable to maintain or recover speed in moving traffic. No crash, injury, or fire resulted. The vehicle was towed to an authorized Hyundai dealer for diagnosis. I have photographs of the instrument cluster taken at the time of failure showing numerous warning indicators illuminated at once. The symptoms I experienced — progressive or sudden loss of drive power, 12-volt/charging-related faults, and failure to restart — appear consistent with charging-control and DC-to-DC converter failures that have been the subject of prior recalls and complaints on Hyundai electrified vehicles. I am filing this report to document the incident as a safety concern.

The contact owned a 2024 Hyundai Santa Fe Hybrid.  The contact stated that while stopped in highway traffic, the vehicle was rear-ended as part of a multi-vehicle collision.  The contact's vehicle was identified as the fourth vehicle in the crash sequence.  The entire rear bumper area sustained significant damage. The first vehicle that originated the crash was distracted by his phone, which caused him to crash into the rear of the second vehicle, causing the second vehicle to crash into the rear of the third, resulting in the contact being rear-ended. No property damage.  The air bags did not deploy. The vehicle was rendered inoperable, towed to a repair facility, and subsequently declared a total loss by the insurance adjuster.  The driver sustained multiple injuries, including a ruptured right breast implant, two lower back herniations, and a neck herniation.  A minor child occupant seated on the front passenger's side also sustained a neck herniation.  The driver and minor child occupant received medical treatment following the incident. The contact also had her service dog in the rear, and due to the severity of the impact, there was difficulty removing the service dog safely from the vehicle. The contact expressed concern that the seatbelt system did not provide adequate restraint during the collision and related the issue to NHTSA Campaign number 26V218000  (Seat Belts).  The dealer and manufacturer had not been notified of the failure. The approximate failure mileage was 30,000

Our 2024 Hyundai Santa Fe Limited Hybrid, which was purchased brand new in Massachusetts in 2024 has been rattling at the passenger side B-pillar since [XXX] and has been in the dealership now 5 times for repairs and 16 service days. They have found that the vehicle is missing spot welds from point of assembly. Hyundai, as repair attempt #5, provided the dealership with documented instructions to hammer and chisel the frame 6.5 inches apart and insert foam NHVpads to see if the rattling would stop, it did not. Hyundai Techline instructed the dealership to repeat this step again. The dealership refused citing major safety concerns with the frame of the vehicle. All documentation including Hyundai Techline guidance is available and submitted with this complaint. Thank you.

Original letter to Hyundai below. The car is currently at a dealer again for repair of the same issue. Fuel pump replaced in Nov 2025 but issue has returned in March 2026. Videos of the issue recently occurring are available. Good morning, We had our 2024 Santa Fe Hybrid lose power while merging onto the freeway in November 2025. I was pressing the accelerator and it did not do anything, just kept rapidly decelerating. Pulled the car to the shoulder and turned it off completely and back on, and the car started up with the engine running which was unusual- typically the car starts up in silent electric mode. It would not accelerate past a few miles per hour. This has now happened on multiple occasions, disappearing for a few days only to return. It has gotten very dangerous to lose speed and acceleration into a busy freeway and almost caused an accident yesterday. We were thankfully close to a dealer (Glassman Hyundai in Southfield, MI) and were able to limp it a mile down the shoulder at low speed to drop it off. However, they are telling us they have no loaners available to provide us which seems unacceptable with a car under warranty with 18k miles on it. Is there anything you’re able to do to assist? Are there any known fixes for the issue that can be reported to the dealer? Thanks, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The National Highway Traffic Safety Administration (NHTSA) has identified the presence of substandard and dangerous driver’s-side airbag inflators manufactured by Jilin Province Detiannuo Automobile Safety System Co., Ltd. (DTN). These inflators were not supplied, approved, or authorized by the vehicle manufacturers and have primarily been found in vehicles that previously experienced a crash and underwent airbag replacement using non-genuine parts. These dangerous inflators have ruptured during deployment, posing a serious risk of injury or death due to metal fragments entering the vehicle cabin. To date, Hyundai is aware of three people who have died while driving a Hyundai vehicle with one of these substandard replacement airbag inflators that deployed in what likely would have been a survivable crash. NHTSA has issued a public advisory urging vehicle owners and service professionals to have vehicles inspected if there is reason to believe that a non-genuine replacement airbag may have been installed. Vehicles with salvage or rebuilt titles, prior airbag deployments, or unknown repair histories may present a higher risk. NHTSA strongly cautions against self-inspection by vehicle owners and recommends inspection by trained technicians.

The National Highway Traffic Safety Administration (NHTSA) has issued an urgent safety advisory regarding dangerous, counterfeit driver‑side airbag inflators manufactured by Jilin Province Detiannuo Automobile Safety System Co., Ltd.
