2024 Hyundai Santa Fe: complete transmission failure

Filed Sep 17, 2026 · Transmission · MS

I am filing an urgent complaint against Hyundai motor America for a direct violation of the national traffic and motor vehicle safety act. The manufacturer is actively refusing to honor and execute the mandated remedy for federal safety recall 263 (the federal safety agency campaign 24V‑529). My 2024 Hyundai Santa Fe XRT suffered an immediate transmission failure, throwing DTC P086800, which is the precise fail-safe error logic covered under this safety recall. When escalated to Hyundai Motor America Corporate Consumer Affairs (Case #XXX), a corporate case manager issued a formal written denial. The manufacturer explicitly stated that the safety recall remedy would not be covered because the vehicle is "past its 10-year/100,000-mile warranty period". This denial is legally fraudulent. Under federal law, safety recalls do not carry mileage, time, or warranty status restrictions. Furthermore, my vehicle is a 2024 model year, making the manufacturer's claim of it being "over 10 years old" a clerical impossibility. Because my vehicle is a primary tool for my livelihood as a rideshare driver, this unlawful denial has caused extreme, compounding injuries. The vehicle entered limp mode and was rendered entirely undrivable. Hyundai's refusal to provide a loaner vehicle or repair the safety hazard has completely cut off my ability to earn an income. As a direct result of this prolonged corporate delay, I have suffered sudden job loss and immediate housing displacement, rendering myself and my family homeless and stranded in the state of [XXX]. I have suffered greatly having to sleep on the streets due to this non-compliance. I request that the federal safety agency immediately investigate Hyundai Motor America Case Management for systemic compliance violations regarding Recall 263, and compel the manufacturer to replace the failed transmission assembly immediately at zero cost INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

2024 Hyundai Santa Fe gasoline model. My VIN was included in Hyundai Safety Recall 263 / the federal safety agency Recall 24V‑529 involving the Transmission Control Unit and potential damage to the dual-clutch transmission. On September 25, 2024, at fewer than 5,000 miles, the transmission failed and the vehicle was taken to a Hyundai dealership. The transmission repair/replacement was approved and the vehicle remained out of service until October 21, 2024. On June 5, 2026, the vehicle would not start and required towing to an authorized Hyundai dealership. The vehicle has remained at the dealership continuously since June 5 and has not been returned to me. The dealer has undertaken multiple unsuccessful repair/diagnostic efforts during the current visit. I am currently being told that the condition involves the engine/powertrain. Hyundai is now sending an engineer to the dealership because the condition remains unresolved. I am reporting this history because this vehicle experienced a transmission failure shortly after being subject to a federal transmission-related safety recall and has now developed another major engine/powertrain condition while still relatively new.

The contact owns a 2024 Hyundai Santa Fe. The contact stated that while driving at various speeds, the vehicle jerked and shuddered and lost motive power. There was no warning light illuminated. The vehicle was taken to the dealer, where the contact was initially informed that the failure was not related to the transmission; however, the dealer later diagnosed the vehicle with transmission failure. The contact was informed that the transmission needed to be replaced. The transmission was replaced, and the contact was advised to pick up the vehicle; however, the failure recurred while driving. The vehicle was taken back to the dealer. The vehicle was not yet repaired. The contact's Attorney notified the manufacturer, who proposed an unsatisfactory settlement. The failure mileage was approximately 28,000.

We just brought this vehicle in for the ongoing transmission problem (previously reported to your agency after the car self-accelerated), as well as the missed seatbelt recall that was not addressed at the last dealership. I advised the service advisor that the seatbelt recall needed to be fixed. The service advisor contacted us several hours later to tell us that they were replacing the transmission. 10 days later we picked up the vehicle after the transmission replacement, and the service advisor told us they did not do the seatbelt repair, citing lack of parts and/or special order. I asked if this was a safety issue and if I should leave the vehicle with them for longer, but was told not to worry about it, and to bring the vehicle back at another time. Fast forward to today, and the vehicle is rolling forward when we start it. This is worse than the way it rolled forward before the transmission replacement. Coupled with the disregard for the seatbelt recall, I believe there is a serious safety issue with this vehicle. I have notified Hyundai Corporate, as well as our attorney, and will be contacting the dealership to drop the vehicle off. I have a video recording of the car rolling forward during startup, but it appears I cannot upload it here. I have forward that video to the above mentioned entities, and am happy to share it with your agency as well.

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.

The transmission was replaced and I picked up my vehicle on 16 September. 23 September, all of the transmission lights, warning, lights and check engine light came on. The vehicle is being towed back to the dealership with transmission issues again.

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.

Less than 6 months of buying the vehicle, Hyundai replaced the transmission and now I’m still having problems..it revved up to 2.3 rpms but didn’t change gears then jerks into gear..not everyday but atleast once a week. I’m waiting now on the dealership to look at my car now..but they’re dragging their feet.

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.

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
