2022 Hyundai Santa Fe Hybrid: sudden loss of power

Filed Feb 14, 2025 · Electrical, Engine · OK

Our vehicle continues to experience loss of power driving , on cold days below freezing. When driving normally this hybrid vehicle will be in hybrid mode at a stop, then when accelerating, the ICE engine will not start to assist the hybrid, causing a bare minimum of power to be available, just enough to pull over. On several occasions this has led to very near rear end collisions from the driver's behind. So far I've been able to avoid injury, as I recognize the condition and am hyper attentive to its possible happening. The vehicle handed shown any Check engine warnings until yesterday. As it was dying I pumped the accelerator to see if it would go, latching a TPS out of range code. The condition has been brought to Hyundai Corporate and dealerships with no repair, and no resolution, they say it's fine. This is well documented by others driving Santa Fe Hybrids, and Tucson Hybrids on forums. No one fix has been established, with some dealerships replacing parts, and others no work being done because their scan tool sees nothing. With dozens of recalls for minor inconvenience issues, I do not understand why a recall for this drivability safety issue has not been mandated! These vehicles are defective, and potentially very dangerous. Loss of power, acceleration when others are behind you anticipating you to go, is a real serious danger, not to mention you being stranded in frigid weather. This began happening at 23k miles and continues today with 48k miles on mine. If the vehicle is shut off, then restarted, it is again drivable, until the next happening. One reason Hyundai, says nothing's wrong, and often blames the owners. I can't be without a vehicle, and Hyundai has washed their hands on this, so I'm stuck Hyundai must be forced into an investigation, and a safety recall on this or nothing will be done. How many accidents or deaths are required to get a recall accomplished?

Was driving home from work on the highway at highway speeds and suddenly lost the ability to accelerate with a "Check Hybrid System" warning. At the time of loss of power, I was crossing a bridge and got stuck in the middle of the bridge. I also notice the oil indicator light come on. The engine remained on as far as I can tell but it wouldn't go with the accelerator pedal pressed. I placed the car in park and turned off the vehicle while blocking bridge traffic. 15 seconds later, I turned the vehicle back on, vehicle said ready to drive. I put the car in drive and everything worked normally as best I can tell. Still nervous driving the car for fear of it happening again. Called dealer service but they were closed. What I don't understand is there was 2 recalls for Hyundai Sante Fe hybrids 2022 but when I put in my VIN it said no recalls. Why is it only associated with a VIN?

Power loss with no warning or errors - hybrid system frequently fails to start gasoline engine when needed, resulting in sudden power loss and limited to 35 mph without warning. Serious concern at intersections and on major roads.

2022 Hyundai Santa Fe Hybrid. This incident has occurred twice at the time of this write up. Both incidents have happened on the first start up of the vehicle engine for the day in the early morning (on the way to work). The temperature outside was cool (10-35 degrees, Maine). On at least one occasion it had rained during the night before using the vehicle. It may have been damp on the other occasion as well. After about 3 miles of driving the vehicle it completely loses power. No amount of movement to the accelerator changes the sudden loss of all power. This is a hybrid and the battery gauge below charge/economy/power rpm area of the vehicle starts to completely and instantaneously drain to what would be zero had I not been able to pull the vehicle over and turn the vehicle off. At this point, on both occasions, leaving the vehicle turned off for a minute and then restarting the vehicle seems to alleviate the problem. The incidents have occurred about 2 months apart and since the vehicle turned 20,000 miles. I also feel like it takes more push on the accelerator to get the same response that I got on day 1 when I drove it off of the lot at the dealership. I also notice that the EV indicator light does not come on as frequently as it used to. It would always come on when coasting - and now sometimes it does not.

Between January and March 2023, the vehicle had lost power twice when attempting to move after a red light. The vehicle would only move about 5 to 10 miles per hour. In order to make the vehicle work again, you have to turn off the vehicle and turn it back on.
