Headed to my work, outside temp 26 deg F, when on hiway entrance ramp, vehicle lost all acceleration. Vehicle is a hybrid, condition no warning lights on dash, vehicle was stuck in EV mode, which the ICE engine would not start to help as normally would do. Hybrid battery began draining very quickly. There was a semi truck right behind me accelerating hard to get on highway.This time I managed to pull over on the debris filled shoulder before the system fully shut down as it has done before with the warning -??? HYBRID SYSTEM FAILURE, PULL OVER NOW ! and loud alarm going off. This is a serious loss of total motive power, which I've reported to Hyundai Corporate, and dealerships for repair before, to which they say " we can't duplicate, all systems are fine", and blame me for the problem. Hyundai has washed their hands of this dangerous situation and won't help me. This is the 5th occasion of this problem, I now know from my experience and reading Hyundai forums this issue is wide spread among Hyundai Tucson and Santa Fe hybrids, with some places replacing parts, that doesn't fix the issue. I know how to react by pulling over immediately, shut off the vehicle completely, wait... Then restart the vehicle, and so far, it will drive normal with no codes or warnings after that, until the next random occasion it happens. This is extremely dangerous in cold weather and around other traffic posing a major collision hazard and stranding someone who knows less about this condition. Hundreds have reported this as per the forums, yet no recall or TSB or real fix has been issued by Hyundai.

The contact owns a 2022 Hyundai Santa Fe. The contact stated that while driving on the highway at 80 MPH, the "power low" warning message was displayed, immediately after the contact vehicle proceeded to decrease in speed. The contact proceeded to pull over onto the side of the road to restart the vehicle. The vehicle was able to successfully restart, and the contact successfully drove to a local dealer where the vehicle was diagnosed however the failure could not be replicated. The vehicle was not repaired. The manufacturer was notified of the failure. The approximate failure mileage was 40,000.

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?

- Flushing, NY, USA

My vehicle made 3 ringing sounds and began to decelerate from 67mph to 0 in less than 2 minutes. I had to pull over quickly to avoid getting rear ended. This incident happened twice already. I took it in to the dealer and they were not able to recreate what happened. This occurrence happened 2weeks ago.

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.

Middle of May 2024 car begins to feel like it's shifting when accelerating and stopping. Nothing found by Hyundai Service Dept. Lakeland. On apx. [XXX] while driving stepped on gas pedal and felt no power. Kept pumping the pedal & car started jerking. Managed to get to light and get in left lane to turn into plaza honking horn. Car slid to a stop at entrance. On apx. [XXX] my husband was driving home and same thing happened. Managed to slide car into our driveway. Both times the car had to be towed to dealership. Two fuel injectors have been changed and when I asked them to change other two they said warranty would not allow. Worst case scenario is if this happens on the interstate traveling at 75 miles per hour. Not only could we be killed but others. Both times there was no warning lights or any other warning. The car just started jerking and lost power. It can very well cause a car to rear end us and a multiple car chain reaction hurting or worse killing others. I am filled with anxiety every time I take the car out for errands. I also saw a similar incident reported in the Better Business Bureau here in Tampa by another person. I reported my incident to Hyundai Corporation by phone and email and asked the rep to reported it to her superiors to see if they could just please let the dealership replace my other two fuel injectors & I was told they could do nothing. The dealership has told me several times the injectors must fail before they can replace. Apparently, the cost of the injectors is more than someone's life.

My vehicle has been having repeated issues within 2.5 years of my purchase. Initially it was the transmission and Hyundai service center with poor customer service kept the car for almost 20-25 days before replacing the vehicle. Now, I have picked up the vehicle for less than a week and I get another Powertrain DTC code P030100 and check engine light on. Hyundai service centers are worst in the country, very poor customer service. I have to take my caribou 100 miles away to a different service center because the in town service center wouldn-??t even look at the car and says has no appointment. I have to drive the car for about 100 miles with engine light on which poses a major risk to the car and myself to even ben able to get the car service done under warranty. The company advertises best warranty in the industry but makes it hard to fix the vehicle under warranty. Please stay away from buying an Hyundai in future. Thank you.

On the second occasion, the vehicle was steered to the side of the road and restarted. The vehicle was taken to a dealer where the failure was not able to be replicated. The manufacturer was notified of the failure. The failure mileage was approximately 10,000.

- Kennett Square, PA, USA

The vehicle shuts off completely when stopped at a stop sign, traffic light, or parking space. This has occurred multiple times. Hyundai can not find the problem after multiple times in the shop. The last time it occurred I was in the middle of a busy intersection and was almost broadsided.

- Northampton, PA, USA

The car completely shut off in the middle of driving and I was unable to put the car into park or use the emergency brake and hazard lights because all of the controls are electronic. The lack of mechanical safety features is a danger.

I was driving on the freeway when suddenly I heard a clunking sound. Suddenly I was unable to accelerate at all. My speed was 60 mph and I had the gas pedal pressed all the way to the floor. Nothing happened and my speed would not go over 60. Then a message began flashing on my dashboard. I cannot remember the exact verbiage, but something along the lines of Hybrid System Failure. My car began losing speed and I was unable to accelerate to make it go faster at all. I lost complete control of the speed control. I was in the middle lane of a 5 lane freeway and struggling to get over since I was unable to accelerate at all. It was an extremely dangerous situation as I could no longer control the speed of my vehicle on a freeway. Finally, I was able to exit to an off ramp. My car continued to lose acceleration and finally came to a complete stop on a side street. My car was then towed to the dealer and they are unsure what the issue is. On doing some internet research, I have found a lot of postings of people having this same exact issue with the Hyndai Santa Fe Hybrid 2022 and I think it's a dangerous defect in the car.

On November 28 2023, I was pulling onto a small highway when an alarm went off, car stopped (engine off) as other cars were coming towards me. The message displayed was "autostop is off. Shift to P or N and start engine manually". Because the alarm was so loud and I was concerned, I snapped a picture which will be attached. I immediately pushed start button and was able to get out of the way. I had not turned the Idle Start Stop (ISS) button to off - so supposedly it was on. (You have to push this button to turn ISS off. This happened twice until I was able to get to service department. After much time (and using a loaner car) Hyundai agreed to provide a new battery because of its health. This happened again. I took the car back and the manager showed me a technical service bulletin - regarding my car - "Rough Shift and Hesitation Improved Logic". This didn't sound like Idle Start Stop bulletin but I was assured it was (attached). Though the stall has not occurred since, the ISS icon at times just isn't there. My dealer is communicating with Hyundai to try to keep my car again and provide a loaner. I am reporting this because many others on Hyundai Forums are describing the same incidents. Yet I haven't seen anyone mention the Technical Service Bulletin, even though many have taken this problem to their dealer. To me this needs to be considered for a recall. I had a daughter and grand daughter in my car and had no idea what to do with cars approaching. Fortunately, just pushing start worked. I have read the manual and know what is required for ISS to work. All requirements were net. It is possible the TSB has fixed stall issue so I am mainly reporting for other drivers.

Was driving on the highway while it was in cruise control and on several occasions when trying to accelerate the vehicle would jerk aggressively and struggle to accelerate. It did this about 3 times on my way to my destination. Took it in and they said they couldn-??t find anything wrong with it nor could they replicate the issue. No work was on done on it.

I was driving in the freeway and all of a sudden my engine power became week. I try to step accelerator but it did not cooperate.

- Ewa Beach, HI, USA

Loss of acceleration while driving. This has occurred multiple times (always while moving or actively driving). The first time we were driving up a significant hill and the car slowed, lost power and we had to pull over and coast back down the mountain to a repair center. The second time, I was on the freeway and lost acceleration causing me to pull off the road in median. The third time, I was at a stoplight and when the light turned green, I had almost no movement after edging into the intersection. Eventually, at about 5 mph, the car regained speed. The check light went on in the first event and the car was supposedly repaired at the second dealership by re-tensioning "pins". However, no lights or warnings went on for incident #2 or #3 that occurred after the earlier repair effort. The vehicle is currently at the dealership service center for it's 7th day of "unable to replicate the problem" after incident #3.

The car was idling for about 30 mins as I waited for delivery of groceries at curbside pickup. I put the car in drive but the motor did not kick on. I was able to drive on electrical power until the hybrid battery died. I lost complete power in the middle of the Interstate but I was able to coast to the shoulder. I had a check engine light and other warning lights on the dashboard but they went away when I restarted the car
