2023 Hyundai Santa Fe: complete transmission failure

Filed Sep 6, 2026 · Transmission · IN

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.

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.

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)

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.

Front brake failure at 3k miles. Rotors warped so badly they failed to properly stop the vehicle. Vehicle shaking immensely Transmission failure at 11k miles. While vehicle is in Drive mode the transmission is stuck in first gear and will not shift. The tachometer was redlining at 6k I had to use the paddle shifters to get the transmission to shift. I was driving the vehicle as a manual transmission when I own an automatic.
