2024 Hyundai Santa Fe Hybrid

When driving, the speed control was not working and the vehicle was not allowing me to accelerate. This has happened three times. The first time it happened to my husband (around beginning of October 2026) while he was on surface streets. He had to pull over and fully restart the car to make it work normally. The second time (on 10/31/26) I was in the middle of driving the car and 15 minutes later I noticed that the gear shift felt off and the car stopped accelerating past 65 mph while on the highway. I had to pull over four times for the car to function normally. We took in the vehicle to the service center at the Hyundai dealership as soon as we could after that incident where they were not able to reproduce the issue and they did not find anything wrong with the vehicle (11/2/26). The third time it happened (11/8/26), I noticed the issue right away as I pulled out of my parking spot. As I press down on the gas pedal, I could feel that the car was hesitant to accelerate. I attempted to drive the vehicle onto the highway, but I had to exit off the highway at the first exit as I felt it was not safe to drive since I could not accelerate above 45 mph. The only way to fix the issue that I found is to turn off the engine, get out of the car, lock it, wait for it to reset fully, unlock the car, and turn it on again. The car never gives me any warning lights on the dashboard ever when this issue occurs.

On September 28, 2026 our 2024 Hyundai Santa Fe would not accelerate while in the drive, while driving. My husband tried to accelerate and while pushing the gas pedal, it would not accelerate. On the screen it told him to pull over, and charge hybrid battery. He pulled off, let the car charge, and all indicators seemed find to drive again. Upon starting to drive again after 10mins of letting it sit and charge, and driving 15mins, the car again would not accelerate, and gave indicators to charge the battery. The vehicle was towed to the nearest Hyundai dealership. At this dealership, they replaced the Throttle Body System (TPS) and 12-v battery which they indicated was drained. Upon asking about the hybrid battery, we were told that those tests or indicators did not flag while running the assessments on our vehicle. Our car was out of service until 10/8. We received the car with a new TPS and brand new 12-v battery. The vehicle was driving, starting, and charging fine for 4 days, until the acceleration once again became an issue. On 10/13, I was driving the car and it would not accelerate, and the check engine light was on. I pulled over, turned off the car, turned the car back on--at this point the car was able to accelerate however still had a check engine light on. Approximately 10mins of driving, the car once again would not accelerate. I tried the same process, called the dealership, and drove the vehicle to the Hyundai dealership in that area. While driving the vehicle on the interstate, the same acceleration problem occurred. YES--multiple people including children have been in danger/safety put at risk due to this. The dealership/mechanic forman was able to drive the car while I was inside, and noted the same acceleration issues on 10/13. Our 12-v battery dying has been a constant and consistent issue since 4/2026, however this is the first time we have experiences loss of acceleration, leaving at time myself, husband, children stranded.

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.
