2022 HYUNDAI SANTA FE HYBRID Power Train Problems

Ever since new this suv will periodically hesitate when trying to accelerate. I have almost been rearended numerous times over the last few years do to this issue. I have had the SUV into the dealer and complained about this issue every time and they cannot seem to do anything about the issue. The have update software (or at least said they have) and done other things and it has made NO difference. This issue almost caused a serious accident just this week when I was trying to merge into traffic on I5.

vehicle will not change out of EV electric mode and return to gas power causing hybrid battery drains to zero, vehicle loses acceleration, you can push the gas pedal to the floor and you have no acceleration, very UNSAFE when you are in traffic, no power to maneuver or avoid other vehicles quickly if needed, potential for accidents, hybrid system warning lights and alarms go on, have to try and pull over safely, battery will not recharge or takes a very long time to do so, only recourse is to shut vehicle off and restart which seems to reset vehicle, which in turn does not leave any warning lights other than codes on to show dealer, very dangerous to lose all acceleration capacity while in traffic, this has happened multiple times with the latest being today 3/23/25, vehicle is available for you to inspect, have had other powertrain codes issues as well, dealer has replaced fuel pump and erg valve but it does not resolve this hybrid issue, this battery drain issue has occurred multiple times but no resolution, help!

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?

When pressing the accelerator from a full stop, the car would either not move at all, idle/roll forward, or unsteadily jerk forward. In addition, the car would brake while driving despite not applying any pressure to the brake pedal. This issue persisted regardless of "drive mode" and no cruise control was in use.

On October 28, 2024 and again on November 26, 2024, a warning light appeared on the dash which said “ check hybrid system stop safely” Within 20 seconds both times , the car became inoperable . When I stepped on the gas nothing happened . The first time I was blocking major traffic , the second time I was on an interstate in the right lane and had time to pull over. In about 15 minutes the light went off and the car drove as normal. The dealer has had the car after both instances , currently for 28 days, and has not been able to replicate the problem .

Transmission faulty needed to be replaced by Hyundai dealership.

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?

Vehicle was being driven at highway speeds and suddenly lost the ability to accelerate with a "Check Hybrid System" warning. After pulling to the side of the interstate, car was shut off and restarted and brought back up to 40 / 50 mph when the same issue occurred with a lack of ability to accelerate and a "Check Hybrid System" warning. The issue appears to be related to some portion of the hybrid drivetrain. Car was then towed but two mechanics (one independent and one Hyundai dealership) could not replicate the issue and the vehicle system did not store any codes or history of the incident. The safety of the driver was put at risk by lacking the ability to accelerate on a major interstate, leaving the driver stranded for two hours waiting on a tow truck on the side of a busy interstate with traffic moving at speeds up to 75 mph.

The contact owns a 2022 Hyundai Santa Fe Hybrid. The contact stated while shifting into reverse (R) and depressing the accelerator pedal, the vehicle hesitated and responded slowly. There was no warning light illuminated. The contact stated that she then shifted into drive(D) and was able to drive; however, the failure recurred while driving and depressed the accelerator pedal. Additionally, the contact stated that the vehicle failed to exceed an unknown speed while driving. The contact stated that she had parked the vehicle and allowed the vehicle to run for 20 minutes. The contact stated that she then turned off and restarted the vehicle, and the vehicle responded as needed while driving. The dealer was notified of the failure and informed the contact that the next availability for diagnostic testing was in a month. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 18,500.

Mileage: 18,500

Loss of power from gas engine at speed car failed over to electric motor at 70 mph on highway unexpectedly and car did not have enough power to maintain speed.

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.
