2024 Hyundai Santa Fe Hybrid

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.

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)

I purchased the Vehicle from Ourisman Hyundai of Bowie, Inc. (Bowie, Maryland) on [XXX] (the “Date of Purchase”). Within a few months of the Date of Purchase, I began having issues with the digital dashboard and heads up display. Both the digital dashboard and heads up display would go completely dark, leaving me an inability to view essential operational and safety information, including but not limited to, the speedometer, rear view camera, blind spot cameras, driving mode, driving gear, navigation, warning messages, lane following assist, tire pressure monitoring system, driver attention warnings, etc. (the “Hazardous Condition”). After multiple calls and emails with the service manager at Len Stoler Hyundai (Owings Mills, Maryland), I took my car to their dealership on November 5, 2024, December 30, 2024, and May 28, 2025, to have Hazardous Condition corrected. Although Len Stoler Hyundai was able to slightly improve the Hazardous Condition such that it was more intermittent – going dark for minutes or hours at a time instead of days at a time - the problem was never satisfactorily resolved. Recently, the Hazardous Condition became less intermittent, and all screens went permanently dark. Since Len Stoler Hyundai closed their doors, I reached out to Heritage Hyundai Owings Mills to address the Hazardous Condition. After a detailed call with a service advisor, I dropped off the Vehicle to them on August 15, 2025, and as of the date of this letter, thirteen (13) days have passed without them resolving the Hazardous Condition, or even returning my repeated telephone calls. To date, Heritage Hyundai Owings Mills remains in possession of the Vehicle. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Driver Assistant cruise and steering components relating to the warning system. The system notification is turned off in the settings; however, the issue overrides the setting. Cruise control and steering assist shuts off after brief but consistant warning to keep my eyes on the road. My eyes are on the road. I can do nothing to stop it from warning. It may happen up to 20 times in a distance of 9-20 miles. This has occured since purchase and occurs everytime the car is driven. While passing on interstate highways the system may shut off. Acceleration stops, steering assist shuts off. Four dealerships have seen the vehicle and a claim was issued by Hyundai America. A Service manager finally, after many request, rode with me after a year of many service appointment resulting in a change of passenger facing camera. No change occurred in the system, it continues to behavior the same a prior to the camera change.

Have a 2024 Hyundai Santa Fe Calligraphy Hybrid with a Drivers Attention Warning problem. The warning turns on frequently when using cruise control. When the warning beeps a few times in quick succession it actually shuts down the system, reduces speed to a crawl, and turns off the engine. This only happens while using cruise control, no issue with DAW when cruise control is off. So can't use cruise control on the highway/interstate. Dealer is no help. This is obviously a safety issue when the engine turns off while driving on an interstate. Thanks
