This is the SECOND occurrence in the past two weeks. I was traveling on a HEAVILY trafficked 10 lane divided interstate, doing the speed limit on cruise control when the vehicle suddenly and inexplicably lost power. It went into "limp mode" (will not go over 30 mph). Thankfully i was able to negotiate to the shoulder but the maneuver was EXTREMLY dangerous as the rest of traffic was moving between 60 and 80 mph. It was harrowing and extremely frightening. Warning lights that were displayed- First, a "Check hybrid system" message appears. Accompanied by SEVERAL other warning lights. Eventually, a "stop vehicle and check power supply" message appeared and would not even move in "limp mode". This appears to be either a bent connection plug or fuel injector issue. …
I was driving the hybrid vehicle uphill on a highway and there was traffic so we were driving under 5 mph for about 20 minutes. When speed picked up I went to accelerate and the vehicle, it never accelerated when I depressed the gas pedal, and stayed in electrical mode rather than switching over to gas. The vehicle then shut off in traffic and I could not pull over safely on congested two lane interstate 17 and I was afraid as vehicles were swerving and driving past and we could not get out safely. The "check hybrid system, Stop safely" warning came on the dash. This vehicle at the time only had 8,808 miles on it and is relatively new. I brought the vehicle in to the dealership but they said "tech scanned for codes. No DTC present. No warnings on cluster at this time. Tech checked for ECM SW upgrades. None available. Tech Road tested vehicle without any issue. …
I was stopped at a red light. When the light turned green, I proceeded to apply the gas and accelerate. I quickly noticed that the vehicle began accelerating at a faster rate than I was intending. The vehicle continued to accelerate without me applying my foot to the gas pedal. Nothing would stop the continued acceleration (application of brake). I crashed into the rear of a vehicle in my lane going approximately 50-60mph (estimate). I am unsure what the issue was that resulted in this crash. In doing some internet searching, it seems it could have something to do with the transition from electric to gas when I was stopped temporarily at the intersection. It could have been a faulty sensor (throttle position) or software glitch. These components have not been inspected by the manufacturer, police, or insurance representatives. …
The contact owns a 2025 Hyundai Santa Fe. The contact stated that while driving approximately 65 MPH, the vehicle unexpectedly decelerated to 25 MPH with a "Vehicle Will Shut Down" warning message displayed. The contact stated that the engine then began to shut down, and although the accelerator pedal was depressed, the vehicle failed to accelerate and stalled. The failure occurred on multiple occasions, requiring the vehicle to be towed each time. The vehicle was towed to the dealer; the vehicle was not diagnosed or repaired and the contact was informed that the failure could not be duplicated. The manufacturer was made aware of the failure and multiple cases were opened, The failure mileage was approximately 3,300.
Original letter to Hyundai below. The car is currently at a dealer again for repair of the same issue. Fuel pump replaced in Nov 2025 but issue has returned in March 2026. Videos of the issue recently occurring are available. Good morning, We had our 2024 Santa Fe Hybrid lose power while merging onto the freeway in November 2025. I was pressing the accelerator and it did not do anything, just kept rapidly decelerating. Pulled the car to the shoulder and turned it off completely and back on, and the car started up with the engine running which was unusual- typically the car starts up in silent electric mode. It would not accelerate past a few miles per hour. This has now happened on multiple occasions, disappearing for a few days only to return. It has gotten very dangerous to lose speed and acceleration into a busy freeway and almost caused an accident yesterday. …
While driving on the highway, my 2024 Santa Fe Hybrid suddenly and without warning lost propulsion power. The loss of power was immediately accompanied by multiple simultaneous warning lights across the instrument cluster, glitching and abnormal behavior of the cluster display, and then a complete electrical shutdown of the vehicle. After the shutdown, the vehicle would not restart. The failure occurred in connection with a software update on the vehicle. At the time of the incident the vehicle had approximately 12,828 miles on it. Losing motive power while traveling at highway speed created a serious crash risk, as the vehicle was unable to maintain or recover speed in moving traffic. No crash, injury, or fire resulted. The vehicle was towed to an authorized Hyundai dealer for diagnosis. …
The contact owns a 2023 Hyundai Santa Fe. The contact stated while driving at approximately 30-35 MPH, the vehicle lost motive power. The contact restarted the vehicle and the vehicle worked as designed for several miles before the failure recurred. The contact stated that several unknown warning lights were illuminated. The vehicle was towed to the local dealer, where it was diagnosed and determined that the failure was due to the accelerator switch. The vehicle was repaired, but the failure recurred. The contact stated while driving 10 MPH in the driveway, the vehicle lost motive power. The manufacturer was not contacted. The failure mileage was approximately 6,800.
The issue I'm about to describe has occurred multiple times during the seven (7) months I've owned the vehicle - including again today. In all cases, I was attempting gradual acceleration to merge onto a highway or high-traffic street (e.g., when exiting a mall parking lot onto a busy city street). When I press the accelerator nothing happens - NO power whatsoever for at least two seconds! And on three of these occasions, I was almost broadsided by oncoming high-speed traffic! I've reported this issue to my dealership (both sales and service) and their response was that this is a known problem with the Hyundai hybrid models BUT that there is NO fix available nor, to the best of their knowledge, is there one in the process of being developed! …
