2024 Hyundai Santa Fe Power Train

On November 18, 2025, at 24,370 miles, the vehicle suffered a catastrophic powertrain failure, triggering a dashboard warning: "Transmission system error! Check transmission oil immediately." The vehicle suffered a loss of reliable motive power. This sudden failure is a severe safety hazard that presents a high risk of stalling or stranding in active traffic, which is especially dangerous as this vehicle is used for a 40-mile round-trip school commute four days a week on local highways. The dealership replaced the transmission, keeping the vehicle out of service for 27 days. However, the exact same critical failure occurred a second time on December 24, 2025, at 24,878 miles. The vehicle was once again completely incapacitated and required a second transmission replacement as well as a new TCU, resulting in an additional 50 days out of service. Two catastrophic transmission failures within a 500-mile span on a brand new vehicle demonstrate a highly dangerous defect that puts the driver, passengers, and other motorists at unreasonable risk of a crash due to sudden loss of power.

Upon first start up of the day, dashboard notification states “Transmission system error! Check transmission oil immediately”, vehicle will not accelerate over 10mph with this error. After turning vehicle off, error is gone and vehicle operates as normal. Dealership is aware of this notification but states they could not duplicate it & found no issues.

I was driving and the car started to loose power and then the engine light came on and the car would not go. Everything happened at one time. The wrecker took the car to the dealer and the dealer confirmed the transmission went out. It is very dangerous for a new car to have the transmission fail while driving. This is a new car. The transmission failed and it is available for inspection at the dealer. The car is currently at the dealer and I am waiting to find out how long it will take to get a new power train.

The transmission is the problem that caused the vehicle to downshift while driving and resulted is a sudden jerk and slowdown in speed. My safety was at risk as the car slowed down suddenly and almost caused the vehicle behind me to rear end my vehicle. But luckily the other driver was able to stop. I previously brought the vehicle to Hyundai service (12/12/24) and they indicated that they couldn’t replicate the problem and there was no situation. The vehicle will be brought to the aforementioned service center again to check the situation (1/07/25). There were no warning the first time it happened, as mentioned earlier and after the second incident the car displayed the message that occurred the first time again which I have attached.

At approximately 1500 miles on the odometer, I started to receive a warning roughly one out of every 3 times I started my 2024 HYUNDAI SANTA FE. The warning would flash red and read "Transmission System Error!, Check transmission oil immediately" and would refuse to move out of first gear, revving to approximately 5000 RPMs. The onboard vehicle diagnostic system reads all systems NORMAL when performed and this error requires a vehicle restart to clear.

Two incidents prior to taking in to the dealership: Thursday, 6/27: Car would not reverse when trying to get out of parking spot. Even though it was indicating reverse it kept moving forward in neutral Friday, 6/28: Car would not go into park. When I tried to set it in park it switched between gears erratically before ending on neutral. Received warning to take it to the dealer and could not turn off car—it stayed in accessory mode. Wednesday, 7/3: Learned from dealer that there was a hole in transmission. No update on how long it will take to be repaired.

My transmission went out at only 1800 miles. It slipped out of gear 2 times while driving. Looking on line I see that I am not the only one. Also people are saying that there 2nd transmission goes out also. I am in the middle of trying to get a buy out.

On Wednesday, August 28, 2024, I was driving southbound on Interstate 95 in Florida at 72 miles per hour in the left lane. As I approached my exit, I attempted to switch to the middle lane when, suddenly, the car stalled. Pressing the gas pedal had no effect, and the car rapidly lost speed. Fortunately, the drivers around me, who were all traveling at speeds exceeding 70 miles per hour, slowed down, allowing me to safely pull over onto the shoulder of the highway. The following morning, I contacted the dealer and drove the car in for inspection. I was shocked to learn that the car, which is a brand-new lease with only 1,500 miles and less than two months old, requires a new transmission. After this terrifying experience, I no longer feel safe driving this vehicle, even after the transmission is replaced. This is my first Hyundai, and in 25 years of leasing cars, ranging from Honda to Maserati, I have never encountered an issue like this. The whole point of leasing a car is to avoid situations like this one. This is completely unacceptable.

DCT transmission issue

UNKNOW

Transmission failure. Problem confirmed by dealership on 7/22. Problem arose on 7/20 with car jumping forward abrublty and started making a clicking noise and hesitating. Did not learn about recall until I logged into my insurance company website to pay my insurance and it listed a recall on my Santa Fe on 7/20. Dropped car off at dealership on 7/22 and was told later that day it would need a new transmission and the dealership was told by Hyundai to give me a loaner car until Hyundai decided what to do about my car. I filed a claim on 7/23 with Hyundai about doing a buy back. I was told I would receive a call in 2-3 business days but have yet to receive one. I called Hyundai on 7/31 and was told my case manager had left a voice mail for me on 7/29 but I have no vm or missed call. I was given my case managers direct phone number and left a vm. Today is 8/1 and my 2024 Santa Fe Calligraphy that I bought on 6/28 and drove for only 3 weeks is sitting in the dealerships parking lot and per dealership, on 7/31 they are still waiting to hear from HYUNDAI. It has 1300 miles on it and luckily I did not get stranded 400 miles away while on vacation. I am very upset that no one contacted me or when problems started to occur with this vehicle, nothing was done and the vehicles were still being sold to the public
