Hyundai Santa Fe transmission failure problems

Filed Oct 27, 2026 · MA · fire

My 2018 Hyundai Santa Fe XL Limited was at a Hyundai dealership for a transmission replacement. While it waited for parts, it was parked outside on the dealership’s lot. It caught fire there while no one was working on it, and the cause is not yet known.

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)

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 (the federal safety agency 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 the federal safety agency should evaluate whether the affected population should include additional model years.

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.

Complete unmitigated loss of acceleration and power while traveling at highway speeds, creating an immediate life-threatening road hazard. Following a warranty engine replacement and mandatory dealer software flash at Clay Cooley Hyundai (Sherman, TX), the vehicle began experiencing powertrain communication issues. While operating the vehicle at 65 MPH on the highway, the vehicle completely failed to accelerate and lost propulsion power, nearly resulting in a catastrophic rear-end collision with an oncoming 18-wheeler semi-truck. Dealership diagnostics claim "no trouble codes present," but live data telemetry confirms the High-Pressure Fuel Pump (HPFP) is actively commanding and delivering a dangerous 1,600 PSI to the fuel rail at hot idle. This abnormal fuel delivery is paired with a severe powertrain stutter in 3rd gear. Service personnel at multiple locations confirm a widespread, high volume of transmission failures and severe drivability issues specifically tied to this recent Hyundai software update. Corporate has denied repair coverage. The vehicle remains an active highway safety hazard and is completely undrivable.

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 federal safety agency will help in bringing this matter to a positive end result, otherwise I have no choice but to pursue formal legal remedies.

The 2017 Hyundai Santa Fe was brought to dealership on 3/27/26 for an oil change and a computer update was completed for Emissions Improvement. Upon picking the vehicle up after service, it was noticeable that it was not shifting correctly. I spoke to the service department and asked if the memory was cleared with the update an if it was having to relearn how I drive and the said it should not be affected. This went on for a few days and I left the car with them to duplicate as there were3 no stored codes. After a few weeks, the Teck Line recommended a new transmission, which Hyundai offered goodwill assistance. As we were waiting for the transmission to arrive from being on backorder, a bulletin for Service Campaign 9C2 was release on 5/18/26 that described my experience with shifting issue almost exactly. The transmission was replaced and the drivability issues still persist. Hyundai says that I must let my car warm up for 1-3 minutes to allow a catalyst to reach temperature and not cause rough shifting. This rough shifting is the effect of the update and thus te reason that my transmission needed to be replaced. Further investigation showed that this update is a known issue and cannot be reversed once installed. Currently, I must start my car in 90 degree weather to warm it up as a result of this update which is not logical in any thought process. I have asked Hyundai to cover the balance of the new transmission as this is a result of thier faulty software update with no success.

Transmission was replaced under warranty by Hyundai in Nov 2024. Engine was replaced at 100600 miles in Nov 2025. Issues with the transmission were happening at that time but ignored by dealership as issues related to failing engine. Our mechanic confirmed in April that transmission was failing and told us to go to Hyundai. We went to dealer in April 2026. They confirmed transmission needed to be replaced. They were going to contact Hyundai USA. We received no updates despite many calls to the dealer. We had to call Hyundai USA directly. They opened a case. Dealer finally called and took car in and requested good faith repair by Hyundai USA. Hyundai USA responded 2 weeks later and is not covering anything. They replaced our transmission in Nov 2024 with a refurbished transmission that they NO LONGER MAKE. Clearly due to the fact that the refurbished part doesn’t work. They now want me to pay $8000 to repair transmission. My car has been maintained on schedule by my mechanic. All paperwork available. I have had Toyotas, Hondas and chevys that have lasted close to 20 years. This has been a horribly disappointing experience. And I now need to buy a new car for my 17 year old instead of handing down. I will NEVER buy another Hyundai. I want everyone to be aware of my experience. Disgusting customer service by Hyundai USA.
