2024 HYUNDAI SANTA FE Complaints

When accelerating from a stop, the transmission fails to engage causing the engine to rev but not allow for movement until the gas pedal is disengaged then engaged again. This happens sporadically and I have not been able to find a pattern or reason for this issue. I have reported this to Hyundai and taken the vehicle in but the dealership was unable to reproduce the issue after driving the vehicle for 20 miles. This is a safety issue as the vehicle does not always accelerate as expected from a stop and could potentially cause an accident.

The contact owns a 2024 Hyundai Santa Fe. The contact stated that while driving behind a trailer at 61 MPH with the cruise control activated, the indicator was activated to switch to the left lane, and the vehicle independently accelerated to the set speed of 68 MPH. The contact immediately depressed the brake pedal to slow down. There was no warning light illuminated. The failure had occurred several times and now occurred whenever the cruise control was activated. The vehicle was taken to the dealer, who was unable to determine the cause of the failure; however, the contact was unable to duplicate the failure. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was 26,434.

The "take a coffee break" system is out of control. Encourages me to take a break repeatedly, even when i have both hands on the wheel and am staring straight ahead. It's distracting and frustrating, and cannot be turned off.

While driving my 2024 Hyundai Santa Fe on the interstate, the “Keep your eyes on the road” alert repeatedly activated even though the driver was attentive and looking forward. After multiple warnings, the system escalated to a message that the vehicle was about to be disabled, which created a serious safety concern. This happened even though the Driver Attention Warning feature is disabled in the vehicle’s settings. The issue appears to be caused by the steering-column driver monitoring camera system falsely detecting inattention. The constant alerts are distracting, and the threat of the vehicle disabling features while driving at highway speeds is dangerous.

Having great difficulty releasing the seat belt. At times, have to repeat pressing red release button. I’ve been using seat belts in more than 50-75 cars on my life experience and never had trouble releasing my seat belt. This problem is consistent with all family members who drive this car. I’m concerned if an emergency situation occurs, my family will not be able to get out of car quickly.

Vehicle was not driven for 2 days. The check engine light is one and says "active airflap issue" the flaps appear to be open when a/c is on and closed when vehicle is off. There is no debri or anything arount the air flaps. This could cause potential overheating and should not happen in a years time. We travel for my husband's job and this could be very dangerous. We thought we were buying a new RELIABLE vehicle.

The transmission was replaced and I picked up my vehicle on 16 September. 23 September, all of the transmission lights, warning, lights and check engine light came on. The vehicle is being towed back to the dealership with transmission issues again.

We had notice that my wife's 2024 Santa Fe Hybrid Calligraphy AWD, is shuddering and vibrating at low speeds 20 to 40 mph always. Probably now is a little more accentuated. There is nothing on the steering wheel, but in the whole vehicle. Because this is not new, and I am not always driving this vehicle, I need your assistance as soon as possible.

Vehicle Information: 2024 Hyundai Santa Fe Hybird SEL VIN: [XXX] Purchased date: [XXX] (Less than one year) Mileage at incident: 12,753 Incident date: [XXX] Dealer: Kengarff Downtown Hyundai Summary of Problem: I am filing this complaint because of a serious safety concern caused by clear dealership negligence and potential engine failure. During a routine service, the dealership failed to add engine oil, but recorded in the service invoice that it was added. I unknowingly drove the vehicle 3–5 miles without oil, and multiple DTC error codes (P052400, P001100, P001400) appeared. The oil warning light, which should have alerted me, did not activate. Although a later borescope inspection stated there was “no immediate damage,” since then, the vehicle has shown: Significant loss of power and acceleration Abnormally high RPMs, even when the car is stopped Louder engine noises RPM is increasing suddenly while driving downhill without acceleration This vehicle is less than one year old and costs over $40,000. I should not be forced to drive a new car that may have hidden or delayed engine damage. Safety Concern: I have a [XXX], and I cannot risk sudden engine failure, stalling, or fire while driving. This is not only a reliability issue, but a serious safety hazard for my family and others on the road. Attempts to Resolve: Reported to Hyundai corporate, case opened. The dealership admitted the mistake but denied responsibility after the inspection. Hyundai corporate stated “no action until further inspection,” despite clear evidence of negligence. I continue to experience performance and safety issues. Requested Action: I urge NHTSA to investigate this incident and hold Hyundai accountable for both the dealership’s negligence and the potential safety defects (oil light failure, possible hidden engine damage). Consumers should not be left to drive unsafe vehicles, especially when children’s safety is at stake. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The drive attention warning system turned off the cruise control. Causing the vehicle to unexpectedly decrease speed on the interstate, which forced the cars behind me to brake hard to avoid hitting me. This system is constantly giving alerts for no reason distracting my attention to the road. I can have both hands on the wheel and looking straight forward and the system gives an alert tone and flashes a message on the screen stating it can see my face. If the cruise control is on it will disengage the cruise. If the cruise is not engaged it just keeps alert every 20 miles or so. I have taken it to the dealer, who showed me how to turn it off , but it still alerts over and over again.
