2023 Hyundai Santa FE other reported problems

UNKNOWN OR OTHER

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.

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.

Vehicle stalled while driving — unsafe loss of power. While driving at normal speed, the vehicle suddenly shut off without warning and the electrical system malfunctioned. I had to pull over and restart car. This created a dangerous situation and could have caused a collision. Prior to this incidenct, the vehicle had intermittent electrical issues during startup (flickering electronics). This is the first time the car has experienced during driving, and is now at the Hyundai dealership. The car has been reported as unsafe to drive. This appears similar to other Hyundai stalling/power loss issues and may indicate a developing safety defect. Requesting investigation.

Two unsafe scenarios in past two months: 1) Driving 80 mph, engine misfire, vehicle will not accelerate past 1 rpm, had to drive home from out of town with very slow acceleration, dangerous to not be able to accelerate efficiently on highways 2) Driving 55 mph, all driver safety systems malfunction, accelaration completely disabled, had to coast to safe stopping point. Restarted vehicle and could drive home with check engine light on, incredibly dangerous for car to lose all ability to accelerate in the middle of a highway.

Today, i received an extended warranty for my horn. There is a known issue with water getting into the horn and causing them to fail. Upon researching this, people have reported having their horns changed several times. This is a safety matter that an extended warranty is not fixing. Please enforce a recall so that this matter may be properly resolved. Canada has already issued a recall, I hope we can do the same. Thank you.

Driving to work and a loud noise (pop) was heard and then I realized the sunroof had basically exploded. Glass was all over the car and all over myself. I immediately got off the road and turned on my hazard lights to assess the situation. This could have caused an accident had I not remained calm. Contacted dealership this morning. Waiting to hear back. No prior warning to this happening.

1. The factory-supplied scissor-type jack that came with my 2023 Hyundai Santa Fe failed. While changing a flat tire on the side of the road, the jack collapsed three times and could not hold the vehicle. Yes, the jack is still available for inspection. I have it in my possession and have provided photographs of the jack, its capacity label, and the incident location as evidence. 2. My safety was put at serious risk. The vehicle fell off the jack three times while I was attempting to change the tire on the road. The car remained on the ground without a tire until roadside assistance arrived. If I or a family member had been under or near the vehicle when it fell, we could have been seriously injured or killed. My wife and three toddlers travel in this vehicle, making this a major safety concern for our family. 3. No. Rosen Hyundai dismissed my concern. Service Manager Jeff Bravieri claimed the jack is rated for 3 tons (6,000 lbs) and blamed user error. But my photo shows the jack's label states 1,200 kg (2,645 lbs). The road was flat. The dealership dismissed my safety concern and refused to replace the jack unless I paid for it. They have not inspected the jack despite my request until the involvement of Hyundai Motor America. 4. Not sure, that vehicle and jack have been inspected by the manufacturer, police, or insurance representatives. However, manager later agreed to inspect it and instead blamed user error. I am reporting this directly to NHTSA because the dealership and Hyundai have not taken this safety defect seriously. 5. No. No warning lights or signs. The jack looked normal. It failed the first time when I used it in an emergency situation. 6. The jack label says 1,200 kg (2,645 lbs). My vehicle weight is 1,724 kg (3,801 lbs) . The jack is under-rated and unsafe. It failed on a flat road. The dealer ignored the evidence. I fear this could happen to others and cause serious injury or death.

Total horn failure, both horns. Took vehicle to the dealership, diagnosed both horns need to be replaced. None in stock. Horns ordered , no dates known by Hyundai when they will be in stock. Hyundai admits it h. Known with many models Driving a car in Buffalo NYwith. Out a horn driving a vehicle,r Nissan , is VERY DANGEROUS and scary. I do not think that Hyundai is taking this issue seriously and they need a recall and plan to fix this problem.

2023 Hyundai Santa Fe Calligraphy repeated horn failures since purchasing vehicle new. Will be having 5th and 6th horns replaced with no effective remedy as vehicle has less than 11K miles on it and this urgently safety failure needs to be corrected. There is no warning of the horn failure until you need them to prevent an emergency/collision warning.

I stopped to fill the gas on my road trip and the gas panel would not open. As a single women driving alone this is not ideal. It took 45 min of continuous unlocking/locking with pushing to get it to pop open. There needs to be an alternative/emergency handle to pull so this does not happen again. I was standing in 32 degree weather the entire time! NOT SAFE

Both horns have failed for the second time since the vehicle was purchased new in November 2023 and is currently showing 25,000 miles. The first set was replaced under warranty at a Hyundai dealership approximately 1 year ago. Not having a functioning vehicle horn is a safety hazard that would fail annual vehicle safety inspection testing in my state.

My back up camera is not working properly. The picture at times is scrambled and starts floating around on the screen. This was not the first time this has happened. I reported it to the dealership service department when I first noticed, about a year ago or longer. They updated the software and told me that would correct the problem. Clearly it did not correct the problem, if it is continuing to have issues.

The horn has broken 4 times. I was told that it is a design defect in the car and there is no permanent fix. Water gets in to the horn when it rains and because of the location of the horn it would have to be moved to fix it. Hyundai is aware of this safety issue and has not issued a recall because there is no permanent fix. They are supposed to be buying back my car but are dragging their feet. I'm sure this is an issue in more than just my car and it's very unsafe for the horn to just stop working.

Vehicles' charging side deck will heat up any phone we put in to charge inside that slot. We brought this to the dealers attention a couple times but they stated I needed to pay a service fee to have it looked at. It began happening a few weeks after we purchased the vehicle. We have not used the port ever since.

AC evaporator drain design problem June, 2024 approx. 3500 miles under warranty, AC evaporator drain line backed up into the passenger front right. Brought it to service - they unclogged and drained the line at no charge. June 2025 approx. 12,K miles under warranty, AC drain backed up again. The excess water drained onto my feet as a passenger and collected under the front seat, saturating the rug area, potentially causing additional mildew and respiratory causing irritation. Service required an appointment. drained it charged $88. Filed a complaint incl Hyundai Motors ; was told the $88 charge was irreversible - cause was weather. The CAR HEALTH HAZARD seems to stem from a major design flaw The air intake is in the windshield wiper cowl resulting in wet tree and leaf debris , bird droppings, etc collect even when the car is not in use. Thus, when heat or air conditioning is activated, air comes in through the air intake and then through the difficult to acces filter recessed behind the glove box , then into the passenger area When the AC drain hose is plugged, it backs up through the dirty filter and then out, to accumulate under the passenger seat allowing more mildew. Re:My 2024 mile blockage, the water was drained, but the filter was not mentioned. In 2025 with the $88 bill, the water was drained no mention the filter. Draining the water does not correct the problem. It should be required at every service the l drain hose is checked, water drained. and filter changed at no charge until a design correction to cover the cowling or an interim solution is installed We lnotice that we have sporadic respiratory problems in the first of miles of riding in all the car From Hyundai Motor America - We expect reimbursement for the $88 service charge. Warranty draining the water and new filter annually. and an NHTSB approved fix of the problem and an NHTSB approved redesign of future models

On [XXX] I was on [XXX] in Houston, TX southbound in the Woodlands area when my vehicle warning light for overheating went on. I pulled over on [XXX] and contacted Vehicle Assistance and the vehicle was towed to my dealer, Northwest Houston Hyundai. There was damage to a tube in front of the radiator and a/c condenser. The damage to the tube was approximately 1/16 of an inch in diameter and supposedly was caused by debris entering through the front grille which is designed like a large egg carton. The dealer spokesperson informed me that they had seen many vehicles like mine (2023 Santa Fe) with the same type of damage. I have been trying to settle this with Hyundai but they feel it is normal road damage and that the wide open grille design that allows it is not their problem. I can't even get them to approve a third party screen to protect the engine radiator from further design. They will not answer the question as to whether or not installing this item will void the warranty or not. It's dangerous to break down on a manor highway in a manor city particularly for us senior citizens. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
