2024 Hyundai Santa Fe Hybrid problems

“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,…”

“Driving the car in a shaded area. All lights went off on the dash telling me every warning. Car stalled out and died on the side of the road. 5th time this exact thing has happened and Hyundai dealer said nothing is wrong.”

“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.”

“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…”

“Everytime with Acc active it activates the Driver attention camera system which never works in sunlight camera reads wrong and disable Acc while driving on freeway all the time due to sun reflection cant even wear polairized glasses Acc never works.”

“Incident Description: I am reporting a recurring and dangerous safety defect involving the ADAS (Advanced Driver Assistance Systems) on my 2024 Hyundai Santa Fe Hybrid. On multiple occasions, the vehicle has exhibited uncommanded steering input. Even when the Lane Keeping Assist (LKA) system is manually disabled by the driver, the vehicle software overrides this command and re-activates the system without driver input, causing unpredictable steering behavior. System Failures & Error Codes: The vehicle intermittently displays a "Check Forward Attention Warning System" failure. Dealership diagnostics have confirmed the following historical fault codes related to module communication: •C164286, C168886, C16B902, C28B981 Related Safety Recalls: This vehicle is currently subject to Recall 265 (NHTSA 24V561000) for main floor wiring harness chafing and Recall 288 (NHTSA 25V808000) for rearview camera wiring tension. I believe the uncommanded steering and camera failures are direct results of the electrical interference or harness damage described in these active safety recalls. Safety Risk: The uncommanded steering override creates an immediate risk of a crash,…”
