Fuel/propulsion system
While driving at freeway speeds in normal traffic conditions, the vehicle experienced a sudden, complete loss of motive power and rapid deceleration. The accelerator pedal became entirely unresponsive. No warning messages, check engine lights, or diagnostic indicators appeared on the dashboard during or immediately after the failure leaving me blind to the vehicle's state. This loss of propulsion on a high-speed live freeway created an immediate, extreme safety hazard, forcing an emergency maneuver across active lanes of traffic without predictable vehicle control. Component or System: Engine / Powertrain / Fuel System (High-Pressure Fuel Pump / Fuel Rail Sensor) Recurring / Prior History:…

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…

I initially reported a rattling noise near the B-pillar to an authorized Hyundai dealership. A repair order was created documenting my complaint. Following further investigation, I was informed that spot welds in the B-pillar area had separated, requiring structural body repairs.

On September 28, 2026, my 2025 Hyundai Santa Fe Hybrid (49,682 miles) experienced a second sudden loss of propulsion while driving on the highway. The vehicle would not accelerate normally, the hybrid battery gauge dropped to a very low level, and the dashboard displayed a warning instructing me to stop the vehicle and leave the engine running to recharge the battery. I pulled over and waited with the engine running until the battery recharged sufficiently to drive to the dealership. This was the SECOND occurrence of a dangerous loss-of-propulsion problem. On August 21, 2026, while driving approximately 70 mph on I-75, the engine RPM increased dramatically despite the vehicle slowing down,…
Sep 28, 2026Seats
While driving on the interstate at highway speed, the power driver's seat began moving forward on its own without any switch being pressed. It didn't stop and kept moving toward the steering wheel. I am 6'3" and normally sit far back, so the seat was pushing me into the steering wheel and I could no longer sit safely or control the vehicle normally. I had to exit the highway abruptly and pull onto the shoulder to avoid a crash. This put me and other drivers around me at risk. Since the incident, the power driver's seat does not respond at all. None of the seat switches (forward/back, recline, height, tilt) produce any movement or sound. I checked the fuses and they are all intact. I have…

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 went into â limp modeâ It is a hybrid and the electric motor was in operative and top speed is around 35 MPH Unsafe to drive
Jun 28, 2026Electrical system
The vehicle has a recurring intermittent failure that can leave it completely undriveable. When starting the vehicle, the instrument cluster displays âCheck Hybrid System,â âCheck Emergency Stopping function,â 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…
