2025 HYUNDAI SANTA FE HYBRID Complaints

SantaFe Hybrid Calligraphy 2025 with about 9000 miles purchased new from Hyundai dealer. Several times and unpredictably, the vehicle loses power while driving mostly on highway 60-70 mph. operator can push the gas pedal to the floor and the car does not accelerate more than about 25 mph. My wife was on an off ramp with no shoulder to pull off. Very dangerous situation. A message on the dash states to "park and let battery charge". The battery is suppose to charge itself while the gasoline engine is operating.A search engine query reveals many folks are experiencing this same situation.

My 2025 Hyundai Santa Fe Hybrid has experienced repeated, dangerously abrupt power loss while driving at highway speeds, causing the vehicle to go into "limp mode" without any warning or prior indication. This safety hazard occurred on three separate occasions: First Incident: 7/29/25; Mileage: 9,205. Situation: While traveling at 70 MPH on the interstate, the vehicle suddenly decelerated to 35 MPH and entered "limp mode" without any warning lights or notifications. Dealer Repair: Replaced ignition coil assembly (Parts: 27301R1H, 27301-2M417). Second Incident: 8/27/25; Mileage: 12,898 Situation: While accelerating to 65 MPH on the interstate, the same loss of power and abrupt forced deceleration occurred, again with no warning. This sudden loss of speed created a serious safety hazard for me and other drivers. Dealer Repair: Replaced fuel pump & O Ring Assy-High Pressure (Parts: 35326-2M500, 35305-2m414 LH). Third Incident: 9/25/25; Mileage: 14,830. Situation: Traveling at 70 MPH on the interstate, the car abruptly decelerated, again entering limp mode. This caused surrounding vehicles to swerve to avoid rear-ending me, putting myself and others at risk. Dealer Repair: Replaced High Pressure Sensor (3534202M400), Packing Fuel Pump (31115-0W000), and Fuel Pump and Tube Assy (31119-L1400). In all three cases, there was never any warning light, check engine notification, or app alert before the incident. Hyundai and my dealership confirmed and replicated the issue during each repair. I have reported the vehicle to the Texas DMV, Hyundai and the dealer.These recurring “limp mode” incidents have repeatedly jeopardized my safety, my family’s safety, and the safety of the public due to the sudden, unanticipated loss of power at high speeds. Since the underlying issue persists and has required three separate major repairs, I am fearful for my safety while operating this vehicle and believe it constitutes a serious safety defect needing federal investigation.

The driver assistance warning system continuosly goes into shutdown mode. Eye monitoring system always states that you are not keeping your eyes on the road. I have tried using different glasses or no glasses. Changing the steering wheel settings also seem to have no effect. This is very dangerous as it will start decelerating and stopping in the middle of a freeway in heavy traffic when this warning is activated. This only happens with the lane keeping assistance and adaptive cruise control are on. Hyundai issued Technical service bulletin 25-GI-001H, but they did not solve the problem

Vehicle was in driveway for 3 days. When I got into vehicle to drive I saw the windshield had a large crack on driver’s side approximately 16” long. No vandalism or rock damage caused this problem. Has to be a stress fracture.

Driver attention warning system constantly gives aggravating notices of "suggest take a break" with chiming sound when driving with or without sunglasses or other glasses. I cannot use cruise control. I have tried several different sunglass types with no success. After first warning, goes off every 4 minutes, either cancelling cruise control when I am using it or just causing annoying aggravation which takes my attention off the road. I cannot turn this feature off. It is so aggravating that it draws my attention from the road ahead and impacts my patience while driving. Due to eye condition, I must use sunglasses while driving in sun. Hyundai did not make this limitation clear when I was buying the vehicle, and they refuse to do anything about it now.

My wife was parking our vehicle near the front of our home, simply rolling forward toward the car in front of her to complete parking on the left side of the street when the vehicle unexpectedly accelerated on its own. The vehicle turned hard to the right, struck the bumper of the parked car she was pulling up behind, continued right across the traffic lane where it hit two parked cars on the other side of the street with significant impact, lifting and turning one onto the sidewalk, at which point our vehicle went across the sidewalk and stopped after hitting a fence. The forward collision avoidance that we have experienced engaging previously, never engaged, despite hitting multiple vehicles on the lefft side and then right side of the street. The collision avaoidance alarms that we have experienced sounding previously, also never went off. The airbags never deployed, despite hitting 3 cars at two different sides of the street, as well as an iron fence that never moved. The vehicle went from traveling less than 5 mph while completing the last few feet of parking to a high rate of acceleration within a path of less than 40 feet, as evidenced by the significant damage it left. Had my wife not come to a stop as quickly as she did, she could have been seriously injured. If anyone had been on the sidewalk - there are 3 shcools on this block that children are often present - someone could have been killed. The vehicle is currently at a body shop being evaluated by insurance adjuster and likely a total loss. We reported tot the manufacturer and they intend to repsond to us by 9/16 and inspect the vehicle in its current state.

The contact owns a 2025 Hyundai Santa Fe. The contact stated that while his wife was driving at an undisclosed speed, the Forward Attention Warning (FAW) system activated. Shortly afterward, the message "System Shutting Off" was displayed, and the Automatic Emergency Braking System briefly engaged, jerking the vehicle and dramatically reducing its speed of the vehicle but not to a complete stop. The vehicle returned to normal functionality, but the failure became a regular occurrence. No warning lights were illuminated. The vehicle was taken to the dealer, who determined that the vehicle was functioning as designed but informed the contact that his wife's glasses may be interfering with the Forward Attention Warning (FAW) system's eye detection ability to monitor her eyes. The vehicle was not repaired. The manufacturer was notified of the failure, a case was opened, and the contact was referred to the NHTSA Hotline for assistance. The failure mileage was 13,000.

The “consider taking a break” warning comes on far too much and has almost made me wreck twice due to being startled.

Vehicle unable to recognize face when wearing sunglasses and disables all driver assist aids, including turning off the cruise control

Hyundai disabling critical vehicle safety systems if people wear sunglasses. I brought MY2025 hyundai santafe hybrid, this has driver attention monitoring system. Since the day i brought this vehicle i have been getting issues related to driver attention warning system. This error is being caused for no reason, this comes on when vehicle comes on and stays on (sometimes for days sometimes for weeks and sometimes for hours). HYundai says this issue is because i have a dash cam in car, error wont go away even when dash cam is removed. Recently hyundai engineers said its because you may be wearing sunglasses. What? Wearing sunglasses will disable AEB and cruise control !!!OMG. I removed sunglasses and tried still wont work. Hyundai sent me list of things not to do, including not to laugh, not to shorten your eyes and not to wink. this is a major safety concern, not allowing drivers to wear sunglass which will disable safety critical systems.
