2025 Hyundai Santa Fe Hybrid power train problems

“I am filing a safety complaint regarding my 2025 Hyundai Santa Fe Hybrid, which I purchased as a Certified Pre-Owned vehicle in April 2026 with approximately 15,000 miles. The vehicle currently has approximately 27,000 miles. While driving on the [XXX], my vehicle suddenly and unexpectedly lost propulsion. The vehicle’s electrical systems remained on, but it would no longer accelerate normally. There were no warning lights, messages, or alerts before the loss of power. I was in active freeway traffic with numerous vehicles behind me. Because my vehicle could no longer maintain speed or accelerate, I was placed in an extremely dangerous situation. I feared being struck from behind by another vehicle. It was a terrifying experience. I was eventually able to pull over to the side of the freeway. I turned the vehicle off and waited briefly before restarting it. I was then able to get off the freeway and reach a gas station. Once at the gas station, multiple warning lights illuminated on the dashboard, and I observed that the hybrid battery was not charging. The vehicle ultimately became undrivable. The vehicle was towed to Centennial Hyundai in [XXX] for diagnosis.…”

“My 2025 Hyundai Santa Fe Hybrid has multiple ongoing problems. Several are intermittent. BRAKES: The brake pedal intermittently sticks when I first start the car. STARTING/ELECTRICAL: On two occasions the vehicle would not start and roadside assistance had to come to start it. It is also sometimes hard to start. The Digital Key on my phone intermittently fails to unlock the doors or start the car. On occasion, all audio is lost at startup, including the radio, speakers, and turn signal sound. The front left speaker intermittently cuts out or sounds distorted. The passenger front door exterior handle/unlock intermittently fails. The driver side temperature knob is stuck at 77 degrees F. POWER TRAIN: The vehicle hesitates/stutters during the first half mile of driving after starting. SEATS: The driver seat memory intermittently fails to move to the saved position when the car starts. SUSPENSION: A creaking, spring-like noise occurs when the car rocks during initial acceleration and braking, possibly from the driver side front. I have reported this to the dealer twice before. Inspection: I have reported these problems to Westlake Hyundai in Thousand Oaks, CA, on…”

“Beginning in early October 2026, my 2025 Hyundai Santa Fe Hybrid Calligraphy has repeatedly experienced a sudden and complete loss of propulsion while driving. During these incidents, dashboard warnings appear stating "Check Driver Assistance System" and "Check Hybrid System. Stop Safely." The vehicle indicates EV mode and completely loses the ability to accelerate or maintain speed. This is not reduced performance or hesitation. The vehicle loses all usable propulsion. The vehicle continues moving briefly while slowing, providing only a short window to reach the roadside. In moving traffic, this creates an extremely dangerous situation because there may be insufficient time or space to safely change lanes before the vehicle slows substantially. The failure occurs without advance warning. Shutting the vehicle off and restarting it temporarily restores normal operation, but the malfunction continues to recur unpredictably. On October 21, 2026, I brought the vehicle to an authorized Hyundai dealership specifically for this problem. The service department reported finding no diagnostic trouble codes and no applicable software updates. No cause was identified, and…”

“On 2 seperate instances while driving down the highway the car suddenly loses power and goes into limp mode. The battery and the engine are not communicating to power the vehicle. It will no go over 30 MPH and then says to pull over and charge the battery.”

“Vehicle was turned on and in park. I placed my child in the back seat, opened the driver door and was able to enter the vehicle. The car began to roll down the driveway, while in park, and ran me over. It continued to roll backwards into a tree and was stopped by rolling into my neighbors home.”

“The vehicle has a recurring intermittent failure that can leave it completely undriveable. When starting the vehicle, the instrument cluster displays “Check Hybrid System,” “Check Emergency Stopping function,” the check-engine light, and multiple warning indicators. The vehicle remains in Park and will not shift into Drive. This has happened multiple times. Disconnecting and reconnecting the 12-volt battery temporarily restores operation, but the problem later returns. After a reset, the check-engine light may remain illuminated for approximately one day before disappearing. During the most recent occurrence, the vehicle became disabled at approximately 8:00 PM in a retail parking lot while my family, including two young children, was with me. The vehicle would not move. We had to leave the vehicle and walk in the rain to obtain tools so the 12-volt battery could be disconnected and reconnected in order to get the vehicle operating again. The problem was reported in writing to a Hyundai dealership before an August 10, 2026 service appointment, including a request to retrieve and document stored and history diagnostic trouble codes. The condition remains…”
