HYUNDAI Complaints

Adaptive cruise control controls the speed limit based on Maps or actual signs was making an error! I was in a 60 MPH area when the system would read the route number sign and mistake it for speed limit. This happened both on state route 80, and state route 70, the car would accelerate up to that speed indicated by the route sign for a few seconds and then realize somehow it was in error and drop down to legal speed. Its a surprise for the driver.

Vehicle on initial start up shows no issue. Driving for a short distance or stationary for a short time. Vehicle instrument panel will show a fault of Forward safety system. Errors on Lane keeping assist, High beam assist, and Driver attention warning. Smart camera module will be hot to the touch causing failure of Front view camera and Front Radar Module.

Size 245 / 45 R 21 It's already my second tire thta gets a bubble on the side wall without any know crash One tire blew mid driving for no apparent reason on less than 10K miles I recommend you recall all those tires they are dangerous

When stopping on uneven ground ,or steeper down hill the breaks fail to stop. They don’t “catch “ to stop. In separate issue is the “emergency steering” alert flashes on dash randomly and takes over when there is no need to anything out of the normal happening, only happen in very short time maybe under a minute but it shouldn’t come on at all when it does happen

I own a 2023 Hyundai Santa Fe Calligraphy AWD equipped with the 2.5L turbo engine and 8-speed wet dual-clutch transmission. At approximately 39,900 miles, the check-engine light illuminated. Hyundai Bluelink diagnostics reported powertrain/TCU diagnostic trouble code P1C2D03, identified as a high-pressure electric oil pump motor position sensor fault. I am concerned because this same diagnostic trouble code and high-pressure electric oil pump/transmission issue was associated with Hyundai Safety Recall 236 (NHTSA Recall 22V746) involving certain earlier Santa Fe model years. Hyundai's recall documentation described the possibility of the transmission high-pressure electric oil pump malfunctioning and causing loss of motive power while driving. My vehicle is a 2023 model and therefore was not included in that earlier recall, but Hyundai has subsequently issued technical service information covering 2021–2023 Santa Fe vehicles equipped with the 2.5T engine and 8-speed wet DCT, including vehicles displaying DTC P1C2D03. The current Hyundai service procedure indicates that affected vehicles may require transmission replacement. I have stopped driving the vehicle because of my concern about a possible loss of propulsion and have scheduled an appointment with a Hyundai dealership for diagnosis. At this time, I have not experienced a loss of motive power or an accident. I am reporting the issue because a 2023 vehicle outside the original recall population is displaying the same fault code associated with the previously recalled transmission condition. I believe NHTSA should evaluate whether the affected population should include additional model years.

I am reporting a serious engine failure involving my 2013 Hyundai Sonata. The vehicle's engine was previously inspected by a Hyundai dealership as part of a Hyundai engine recall. I followed Hyundai's instructions and brought the vehicle to the dealership for the required inspection. I was informed that the engine passed the inspection, and an orange marking was placed on the oil dipstick. The Hyundai dealership should have the service record documenting this recall inspection. Many years later, at approximately 120,000 miles, the same engine suddenly failed without warning and became locked/seized. A mechanic attempted to turn the engine and determined that it would not turn. I understand that many years had passed and the vehicle had accumulated additional mileage since the recall inspection. I am not claiming that the previous recall issue necessarily caused the current failure. However, I believe the circumstances warrant investigation because this is the same engine that had previously been inspected under a Hyundai engine recall and determined to have passed the inspection. The vehicle had been routinely maintained. Much of the routine maintenance was performed outside Hyundai dealerships by a mechanic in my family and by me, so the Hyundai dealership service history may not contain all maintenance records. I am concerned that the sudden engine seizure may represent a safety-related engine defect or may potentially be related to the previously recalled engine condition. An unexpected engine seizure can result in a sudden loss of propulsion and create a significant safety risk if it occurs while the vehicle is being driven. I am requesting that NHTSA review this complaint, including the vehicle's recall history and any related complaints or investigations involving the 2013 Hyundai Sonata, and determine whether this failure warrants further investigation. The Hyundai dealership that performed the recall inspection have documentation of that inspection.

This report is an addendum to report 11762283 that was made yesterday. The vehicle allows driving with the rear liftgate ajar, however under some circumstances it engages the EPB when the vehicle comes to a stop while the gear state is still Drive. The gear state of the car remains in Drive when the EPB engages. This presents the driver with the choice, in the middle of the road and possibly in the middle of an intersection, of either exiting the vehicle and rearranging contents of the vehicle to allow the rear liftgate to close, or activating the accelerator to continue driving with the traction motor overpowering clamped EPB. Neither option is safe. I have attempted to reproduce this unsafe state of the vehicle and was successful in one case and unsuccessful in another. My hypothesis for the differentiating factor is the top speed reached prior to decelerating to a stop: in the first case, 13mph, and in the second, 15mph. I have attached a single frame from one of two videos, of the successful case. The instrument display shows gear state is Drive, the car is moving, high torque is being applied by the traction motors (but typically the screen center shows ADAS state, and there is no indication of instantaneous traction torque), and the EPB is engaged. The car is in the middle of an intersection at the time.

I bought the car about 2 days ago and while driving the car caught fire and I had to call my local fire department. I never hit anyone or did anything it just caught fire randomly.

The low-pressure fuel pump module assembly, located directly beneath the rear passenger seat cushion, experienced a plastic housing failure. A stress fracture on the upper plastic fuel outlet nipple caused raw liquid gasoline to actively weep and pool on top of the module inside the passenger cabin. This component is retained and available for inspection upon request. RISK TO SAFETY: Raw liquid gasoline pooling inside the interior passenger compartment creates an severe, immediate fire and explosion hazard. Additionally, vehicle occupants were exposed to toxic fuel vapors while driving. INSPECTION & DEALER CONFIRMATION: An authorized Hyundai dealership inspected the vehicle and confirmed raw fuel leaking at the top of the fuel pump module assembly. This exact module had previously been removed and disassembled during a 2024 manufacturer recall service to replace the internal fuel filter and tank seal. Stress applied to the plastic fittings during that recall service appears to have caused the plastic top-hat to fracture over time under line pressure. Hyundai Corporate was notified of the safety hazard and prior recall history, but refused assistance. WARNING SYMPTOMS: The failure began with a strong, persistent fuel odor inside the vehicle cabin. No dashboard warning lights, check engine lights, or diagnostic trouble codes (DTCs) triggered prior to or during the failure. SUMMARY: A stress-fractured plastic fuel pump housing allowed raw fuel to pool in the passenger cabin following a prior manufacturer recall repair involving the disassembly of the same component.

All four rear/side door latch mechanisms have exhibited intermittent failure to release the door from the interior and/or exterior handle. Repeated operation or increased force can sometimes cause the door to release. This creates a potential safety hazard because an occupant may be unable to exit the vehicle through an affected door during an emergency. The manufacturer has previously issued an extended warranty/TSB addressing this latch failure, but the vehicle is now beyond the 10-year extension period.
