What 199 owners told NHTSA about the 2023 Hyundai Santa Fe

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.

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.

We were at full stop with Auto Hold feature enabled. Car lurched / jumped forward with no depression of the gas pedal. This caused us to strike the car in front of us.

The contact owns a 2023 Hyundai Santa Fe. The contact stated that while driving and decelerating to approximately 10 MPH onto an exit ramp, the vehicle suddenly stalled and failed to restart. The contact noticed that there was blue smoke coming from the exhaust pipes, and several unknown warning lights and messages illuminated, including the Check Engine warning light. The vehicle was towed to the local dealer, who diagnosed that a fuel injector had failed and needed to be replaced. The vehicle was not yet repaired. The manufacturer was not yet contacted. The failure mileage was 35,652.

I was driving down the road and came to a stop at a stop light. After accelerating again my car lost the ability to increase speed above 20 miles/hour and would not shift gears. I was heading to the turn lane to get on the interstate and quickly had to change lanes to find an area to pull over as I could not reach highway speeds. I turned the car off. I turned the car back on and the problem resolved. This is the second time this has happened. I have seen this problem mentioned dozens of time on Reddit message boards including Hyundai buybacks on some of these vehicles. It doesn't sound like Hyundai has any idea what is causing this issue. This issue should be looked into further.

While running errands around town, I noticed my 2023 Sante Fe 2.5T was sluggish shifting out of first gear into second. The RPMS revved to about 3K before the transmission shifted into 2nd. I didn't notice any problem shifting into 3rd and above. I drove to a gas station for fuel and shut off my car. When I started it and began to drive, I received an immediate warning to take the car to a dealer and the check engine light came on. The car had the same problem getting out of 1st gear at each of the traffic signals I got caught at on my way to the dealership about 2 miles away. The following day, the service department contacted me and determined I needed a new transmission due to the failure of the Dual Clutch electric high pressure oil pump in the transmission. They submitted a parts request and Hyundai approved a refurbished DCT warranty replacement. The transmission only has 50200 miles on it I am second owner but the car was a CPO so I have full warranty coverage. I was given a loaner under Hyundai' warranty provisions. My main concern is that although this vehicle is a 2023 Sante Fe, it was put in service around August of 2022 and would therefore have the same transmission as the 2021 and 2022s covered under Hyundai recall 236, but this has yet to be acknowledged as far as I know. Please investigate my situation and consider further requirements of Hyundai! Sincerely, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

My vehicle activates the emergency braking system while driving. It has happened several times now, almost causing a collision. I took it to the dealership, they held it for a week and gave it back to me telling me they could not find anything wrong with it. They did not fix anything at all. It has since done it once more.

Shifter malfunction has appeared since I bought the vehicle new. Once I took it in, they said it was the software. The vehicle now skipped and hesitate in the lower gears. When in high gears ride fine. But once it stops and start driving again, lower gears won’t drive properly. Drives with hesitation and skips.

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.

While driving on the interstate, while using cruise control, my vehicle braked and decelerated, uncontrollably. The collision alert alarm went off. I forced the vehicle to accelerate and it stopped the braking and the collision alarm ceased. I took the car to the dealer and they spend the day checking it over. They said they couldn’t get the same reaction I reported, but reset the cruise control. On my way back home on, again on the interstate, and with the cruise control activated, it again had the same failures. I called the dealer and told them. They asked if I had recently mounted any new equipment on the windshield. I said I had Velcro attached and EZPASS toll reader. They asked me to remove it, because might be interfering with the cruise sensor. After I removed it, and while continuing on the interstate, with cruise activated, it again repeated the same failures. The dealer arranged to have my vehicle towed to their shop.

It is not just this vehicle; it is ALL vehicles with adaptive cruise control and automatic emergency braking. When sensors get snow or debris on them, they shut the vehicles down without warning. I have had 3 times this winter when the roads were fine, cruise control set, and because another vehicle was kicking up road salt, the vehicle instantly shut off the cruise control without any warning to the driver, all 3 times I had traffic behind me at 55mph or on the highway at 70mph. The emergency braking is another issue, as it will bring the vehicle to almost a stop, and does not take into account if there are other vehicles behind it or not! How more people have not been killed because of these 2 systems is beyond me! BOTH of these systems and the vehicle they are on NEED to be recalled and either sensors removed or workarounds implemented, that at least give the driver some advanced notice before the cruise control is turned off or before a vehicle decides to hard-brake itself!

The front rotors need machining every 10,000 to 15,000 miles. The rotors experience exceeding distortion due heating by the brake pads. When brakes are applied, there are large vibrations in the front suspension which inhibits braking. This is especially true when braking on wet pavement where stopping distances become unsafe.

The contact owns a 2023 Hyundai Santa Fe. The contact stated that while operating the vehicle, the horn was inoperable and inaudible when pressed. The cause of the failure was not yet determined. The local dealer and manufacturer were not notified of the failure. The failure mileage was approximately 31,000.

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.

On March 4, 2026, at approximately 7:30 AM EST, while driving my 2023 Hyundai Santa Fe Limited on [XXX] , the vehicle experienced a sudden loss of propulsion while traveling at approximately 70 mph (posted speed limit). The vehicle would not accelerate or maintain speed and would not move forward when placed in drive, indicating a failure within the powertrain/transmission system. The vehicle is currently located at a Hyundai dealership and is available for inspection upon request. This incident created a significant safety risk, as I was traveling at highway speed in active traffic when the vehicle unexpectedly lost the ability to move under its own power. This placed me at risk of being rear-ended and made it difficult to safely maneuver out of traffic. The vehicle was inspected by a Hyundai dealership. Diagnostic trouble code P284001 (Shift Fork “D” Position) was identified, and I was informed the failure is transmission-related. The condition was reproduced by placing the vehicle in drive, at which point the vehicle would not move. The vehicle has been inspected by the dealership. The manufacturer has been notified but has not physically inspected the vehicle. No police or insurance inspection was involved. There were no warning lights, messages, or prior symptoms before the failure. The issue occurred suddenly without any indication of a problem.

Oil pan leak.

I have been fighting this issue now for 2 years, vibration while driving interstate speeds, especially right rear seat. I have had tires replaced twice trying to fix balance issue only to find out that one rim will not road force balance correctly, even with tire matched it only reduced road force balance to 20lbs (30lbs with out match). I have had it at discount tire and Gettel Hyundai of Lakewood ranch, FL several times. Hyundai sent a senior tech to look at tires, did not speak to me to get explanation of my concern, did a balance, got same numbers and said was good to go. My other 3 rims have a max road force of 12lbs without even being matched. This causes vibrations when driving, extra wear and force on the tire and is a safety concern. This rim is the issue and Hyundai refuses to fix it.

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.

While driving on the interstate at 70mph the vehicle’s fuel injectors failed causing the vehicle to lose power suddenly.

On 6/7/2023 with the original owner, the vehicle displayed code P1c2D03, according to carfax history the transmission was replaced 7/12/2023. I purchased the vehicle in May, 2025. In December, 2025, while driving to work I experienced intermittent loss of ability to accelerate, followed by the vehicle again displaying code P1C2D03 in the Bluelink app. The dealership performed a software update and told me to come get my car. On Monday, February 16, 2026, I started the vehicle and the dash displayed "Transmission error. Check transmission fluid immediately!", I again had it towed to the dealership where it has remained for the past three weeks. Now I have been called again to pick up the vehicle as the dealership cannot duplicate the error. At this time I am unsure if the service center actually checked the transmission fluid as the warning indicated should be done.

I am submitting this complaint regarding a safety-related incident involving my 2023 Hyundai Santa Fe on February 14, 2026. While driving, the vehicle suddenly began to overheat, creating an immediate safety hazard. I was close to my home and was able to return there safely, but once parked, I observed coolant leaking from the front of the vehicle. Due to the risk of further overheating or engine failure, the vehicle was not drivable and had to be towed to a local Hyundai dealership. At the time of the incident, the vehicle had fewer than 38,000 miles and was purchased brand new. Despite this, the dealership informed me that the repair would not be covered under warranty, claiming the radiator damage was caused by “road debris.” However, they did not provide any evidence of an impact, puncture, or external damage. The only documentation offered was a video showing coolant spewing from the radiator after a technician inserted an object into the grille. This video does not demonstrate any pre‑existing road damage or confirm that debris caused the failure. I requested proof of actual damage multiple times, including photographs or inspection notes showing an impact point, but none was provided. Without verifiable evidence of external damage, I am concerned that this may represent a premature component failure or a potential safety defect in the cooling system. The sudden overheating while driving, combined with the lack of substantiated cause, raises significant safety concerns for me and potentially for other owners of this model. Thank you for your attention to this matter.
