Automatic Transmission Control Module problems of the 2025 Hyundai Santa Fe

The 2025 Hyundai Santa Fe hybrid has had multiple occasions, most recently on February 3, 2026 with 12,330 miles on the car, where the gas-powered engine fails to provide any power to the drivetrain. The car experiences vast power loss and enters "limp mode" where only the small hybrid battery is powering the vehicle. Max speed ranges from 10 - 25mph and there is little, if any, acceleration, even when the gas pedal is pegged to the floor. It is necessary to pull over, engage the flashing safety lights and try to find a safe place to park. After turning the vehicle off and on several times, eventually, the gas engines re-engages. The first incident of this type for this vehicle was on August 7, 2025 with approximately 4,400 miles on the vehicle. It was taken to the dealer, key Hyundai of salem, who could not find any dtcs and could not replicate the problem. They said "bring it back if it happens again. " they next time was on February 3, 2026 where it happened several times on a trip to and from a local restaurant. This time, at dtc code of p088000 powertrain / powerloss was recorded and reported. However, by the time the car was seen by key Hyundai of salem on February 5, 2026, the code has cleared itself. Hyundai's corporate policy is that historical codes can not be used for warranty claims. So, the dealer tried one potential fix, cleaning the tcm connectors under the driver's seat, and returned the vehicle stating that Hyundai corporate would not authorize warranty work unless/until the car was presented to the dealership with a current / live dtc or visible broken parts. It seems unsafe to put a vehicle back on the road that could lose power and drivability at any time for no apparent reason. I am aware that there have been several other reports of similar power loss / limp mode situations by owners of 2024-25 Hyundai Santa Fe hybrids. At the moment, I am told that there is no current technical service bulletin on this from Hyundai.
