TRAILER HITCHES

Hyundai Motor America (Hyundai) is recalling certain 2019-2023 Santa Fe, 2021-2023 Santa Fe HEV, 2022-2023 Santa Fe Plug-in HEV and Santa Cruz vehicles potentially equipped with a tow hitch harness installed as original equipment, or purchased as an accessory through a Hyundai dealership. Water accumulation on the tow hitch harness module printed circuit board (PCB) may cause an electrical short, which can result in a fire.

POWER TRAIN

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.

ELECTRICAL SYSTEM,SERVICE BRAKES,FORWARD COLLISION AVOIDANCE

Collision warning sensor alarm randomly comes on my dash and my car slams on the breaks. Very dangerous, I’m scared to drive down the highway going 60mph. 80,109 miles 2023 Hyundai Santa Fe. I have not brought it in to a Hyundai dealership because they want a diagnosis fee and everything else. Hyundai should fix it. This alarm has happened several times than it will go away and come on like 3 times in a row, usually daily when I use the car

POWER TRAIN

Subject: Formal Dispute: Warranty Breach and Failure to Repair – 2023 Hyundai Santa Fe Timeline & Facts:11/2/25 (~52,000 miles): I officially reported an intermittent loss of power and severe engine revving (up to 7,000 RPM). This created a severe safety hazard when merging and accelerating from an idle stop.3/28/26 (Under 60k miles): After months of diagnostic delays, Hyundai confirmed the Dual-Clutch Transmission (DCT) needed replacement under the 60,000-mile warranty. A Hyundai Case Manager tracked the issue.Service Delay: Hyundai delayed repairs due to a lack of loaner vehicles, which were grounded for recall updates. Commuting pushed my mileage to 60,218. The Case Manager assured me coverage was locked in because the defect was documented before 60,000 miles.4/8/26: Due to corporate protocol, they ordered a valve body installation instead of a new transmission.8/11/26: The valve body failed. Hyundai delaership resubmitted the transmission replacement request. Corporate denied 100% coverage because the odometer was now over 60,000 miles (60,218). They are offering only 80%, leaving me with a $1,000 plus out-of-pocket expense.Legal & Contractual Position:Hyundai is contractually and legally obligated to cover 100% of this replacement. Under federal and state consumer protection laws, any defect reported prior to warranty expiration must be fully repaired by the manufacturer, even if the final repair occurs after the mileage threshold. The current mileage is a direct result of Hyundai’s internal diagnostic and loaner delays.Demanded Resolution:I demand that Hyundai cover 100% of the transmission replacement costs immediately. I am hoping this escalation to the NHTSA will help in bringing this matter to a positive end result, otherwise I have no choice but to pursue formal legal remedies.

POWER TRAIN,UNKNOWN OR OTHER,FUEL/PROPULSION SYSTEM

This complaint concerns a serious, unresolved powertrain/propulsion safety defect in my 2023 Hyundai Santa Fe. While traveling approximately 70 mph, the vehicle suddenly lost propulsion and would not accelerate normally while surrounded by highway traffic.MOST IMPORTANTLY, THERE WAS NO WARNING OR ADVANCE INDICATION. No warning lights, messages, or symptoms appeared before the loss of propulsion. I had no opportunity to anticipate the failure or prepare to safely exit traffic. This placed me and other motorists at immediate risk of a serious or potentially fatal collision.A Hyundai dealership inspected the vehicle and documented DTC P284001, Shift Fork D Position Fault. Despite this documented fault, the underlying safety issue remains unresolved. Hyundai has not identified a permanent correction or established that the vehicle is safe to operate.There has not been another incident because I will not risk another sudden loss of propulsion by driving the vehicle. The absence of another failure does NOT mean the problem is resolved. The vehicle remains available for inspection.I have repeatedly sought assistance from Hyundai and the dealership without a meaningful resolution. Newer information regarding a possible computer reset/relearn procedure has also been presented, but the dealership refuses to perform it.I reviewed NHTSA complaints for 2023 Santa Fe vehicles and found multiple reports describing similar safety symptoms, including sudden loss of propulsion, inability to accelerate, abnormal transmission shifting, and loss of speed. This raises serious concern that this may not be an isolated failure.A vehicle that can unexpectedly lose propulsion at highway speed WITHOUT ANY WARNING creates an extreme crash risk. I respectfully request that NHTSA review the similar complaints, investigate whether a broader transmission/powertrain safety defect exists, and determine whether corrective action is necessary before this results in serious injury or death.

ENGINE

I was driving, and the SUV all of a sudden lost power. I was trying to press harder on the gas pedal to keep up with the traffic, but the SUV was stalling. The SUV would not move, and as I kept trying to press on the gas pedal, a roaring noise like something was trying to turn but the engine kept trying to move the car. It felt like something in the car was trying to move but something kept slipping. I had to turn the car off in the middle of the street and restart it before it would move. Cars were blowing their horns. This is a safety issue and a dangerous Problem. The SUV just did the same thing a few days ago. I am calling the dealer to see what is wrong. I brought this car new 2023. It is under 12,000 miles

UNKNOWN OR OTHER

The horn stopped working.

POWER TRAIN,VEHICLE SPEED CONTROL

COMPONENT/SYSTEM: The powertrain launch control system — the Transmission Control Unit (TCU) and 8-speed wet dual-clutch transmission paired with the 2.5T engine — fails to deliver engine power in response to full accelerator input from a stop. The engine does not rev and the vehicle does not move for approximately 1–2 seconds despite the accelerator pedal being fully depressed, then power engages abruptly and violently. The vehicle is available for inspection upon request. SAFETY RISK: The failure occurs when launching from a stop into intersections and cross-traffic. In the most recent incident, I was turning left across the roadway from a stop with an oncoming vehicle approaching. I applied full accelerator and the vehicle did not respond at all for approximately 2 seconds — no engine response, no movement — leaving me stationary in the oncoming vehicle’s path. Power then engaged violently and without warning, causing the vehicle to lurch across the road. I was nearly struck. Similar events have occurred multiple times throughout my ownership; this was the closest to a collision. DEALER CONFIRMATION: Not yet inspected by a dealer. A dealer service appointment is being scheduled. OTHER INSPECTIONS: The vehicle has not been inspected by the manufacturer, police, or insurance representatives. WARNING LAMPS/PRIOR SYMPTOMS: No warning lamps or messages have appeared before, during, or after any of the events. The failure is intermittent and occurs without warning. The condition has been present since I purchased the vehicle in October 2022 and has occurred regularly throughout ownership — numerous occurrences over more than three years. No warning lamps have ever accompanied it. ADDITIONAL: Condition persists with Idle Stop & Go disabled, ruling out engine-restart delay. Same 8-speed wet DCT was subject to Recall 236 (NHTSA 22V-746) on 2021–2022 models for similar throttle non-response; 2023 excluded despite identical hardware.

SERVICE BRAKES

My dealership has reground the rotors on my car twice. Now with less than 40,000 mileson the car the brakes need ground again. The issue with the brakes is it causes the front end of the car to shake when the brakes are applied. This could lead to loss of control on down hill stops in slippery conditions.

VEHICLE SPEED CONTROL,UNKNOWN OR OTHER,LANE DEPARTURE

First Failure occurred 7 months after purchase at 5,270 miles on August 1, 2024. The vehicle suddenly went into "Limp Mode" abruptly decelerating to 25 mph with a non-responsive gas pedal. A code reader displayed PO653 Sensor Reference: "Voltage B Circuit High". Dealer found corroded wire to battery and cleaned it. Second Failure: Horn loss to 1 tone. Fixed at 30K mile dealer service on June 12, 2026 and found to have faulty packing resulting in corrosion. At the same standard service the Brake System was flushed. 3rd Failure was 5 days and 437 miles (30,712 miles) after the 30K dealer service. On June 17, 2026 during my early morning commute while merging onto the interstate, alarms began to blare and the gas pedal suddenly became unresponsive. The initial alarms read Blind Spot Failure. Car would not accelerate from 40 mph that it was going coming down the bridge ramp so I took the very close off ramp down from the aqua duct and the console display alert showed "Engine Management System: details: Braking and Body Control System with a recommendation to get "a full system check...TODAY". I brought it to the dealer that afternoon and as of yesterday, 6/26/26 they can find nothing wrong, declaring it an intermittent issue and asked me to come get the car, refusing to continue looking or providing alternate options other than referring me to Hyundai Consumer Affairs.
