2023 Hyundai Santa Fe Hybrid

As I was driving today my Santa Fe Hybrid lost all power while on the road. The hybrid battery gauge went from 3/4th full to empty in 20 second and I could not get the vehicle to move. Thankfully there was no one behind me and I could safely pull off. When I stopped and restarted the car, the system said ready to drive but the car wouldn't move

Occurred on [XXX] while travelling in the middle lane of a 3-lane highway just west of Raleigh, NC and heading west. The Emergency Brake Light came on, the car stopped suddenly and my head shook from side to side. This could have been a major accident if the traffic wasn’t light. I do not tailgate and there were at least 6-8 car lengths between me and the car in front. No cars on either side. There was no beeping warning from the vehicle about being too close to other vehicles before the car stopped. I pressed on the gas pedal and the car moved forward. The weather was about 50-60 degrees, dry road and sunny. Next Step: Called Hyundai Customer Care on [XXX] and was advised to bring the vehicle in for inspection and correction. Took the car into the Hyundai Autonation dealership in Buford, GA, where the vehicle was purchased. They found nothing wrong. Note: Have researched this problem online and found multiple instances of the same occurrence.

In a parking lot at a church I slowed down, going 1 mile per hour or less. Upon taking my foot off the accelorator to put my foot on the brake pedal, so I could come to a complete stop, the moment my foot came off the accelorator, the engine reved up and lunged forward at about 10 mph. I was suprised and took an extra second to apply the brakes. In the mean time, my car went over the curb, grass and onto the side walk, a good 10 feet. If anyone had been on the side walk, I would have hit them. Additional information: the transmission was in "Snow Mode", it was snowing and cold outside. Attached photo shows tire tracks of the incident.

4 times there has been an error message with a large P symbol and a red triangle on the dash board. The large P is surrounded by a yellow circle and it says below to check P Button. This is an intermittent situation and does not always do it when at the dealer, BUT they have witnessed it. They tried 2 fixes but neither worked. I am concerned since there is a red triangle at the bottom of the dash that this is a serious issue. Hyundai will not expedite this and will not allow me to speak to anyone about it that might be able to explain what might be causing this issue. Customer service just says we couldn not replicate the problem. I told them I understand this. I WISH to know what is causing the computer to send this message and they will not tell me or look into far enough to determine what it is. I am not driving the vehicle until they can tell me if it is a safety issue or not and they will not do that.

I purchased a brand new 2023 Santa Fe hybrid in August 2023. So far, on four separate occasions (Oct ‘23, Dec ‘23, Jan ‘24, Feb ‘24) I have lost accelerator/gas pedal power while driving down the highway. There is no warning, no lights on dash, nothing. I just all of the sudden lose power. On one occasion in particular, [XXX], I was driving on the highway with my 5 year old in the back seat. I suddenly and totally lost all accelerator/gas pedal power while in the passing lane. I rapidly lost speed and was decelerating with a truck directly behind me and another vehicle to my right in the regular lane. I had to quickly turn on my emergency flashers and pray the truck behind me was paying attention and didn’t hit me. I was jamming up traffic until I was able to get pulled over off the road. My vehicle has been into Hyundai’s garage a total of four times now for the same issue. They have yet to find the root of the problem or fix it. I recently picked up my car on [XXX] from the garage and exactly two weeks later it did it again, this time with my husband in the car so it is once again back in the garage. The last trip to the garage they were able to duplicate the issue but can’t find a cause. Twice my check engine light came on after the fact but only two of the four times. I do not feel safe driving this vehicle but corporate Hyundai did an “investigation” into my case and told me today they found I am not eligible for a refund or replacement and to continue to take it to a certified Hyundai garage if/when I continue to have problems. I’m very concerned I’ll be in a traffic accident when this happens again and now the occurrences are happening more frequently. This not only puts myself and my passengers in danger but other vehicles on the road around me as well. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The automatic emergency braking system engaged (the red warning flashed on the dashboard and tone beeped) while I while driving on the highway at 65 mph, in clear weather conditions. This engagement caused the steering wheel to jerk violently left and right, almost causing the car to fishtail on the highway. There was a concrete barrier next to the lane I was driving in, and this was a very dangerous situation. Luckily, there was no car in the lane next to me.

The engine/ability to accelerate seemed to fail. It would not accelerate past 45mph and then couldn't even maintain that speed, even with the pedal to the floor. The engine sounded like it was revving at high RPMs and wasn't shifting into gear, even though it had just been in drive and operating normally. Yes, it is available for inspection. My safety was put at risk by not being able to accelerate when merging onto the highway, leading me to be going much slower than the traffic around me. I have not asked the dealer to reproduce the problem. The component has not been inspected. There were no warning signs, messages, or alerts of any kind. There was no information about the status of the car whatsoever.

Bought the car in July 2023. Nov 23: I had a check hybrid system followed by check engine + red battery warning while driving in the interstate. The car lost power abruptly. Coasted out of the interstate, took the exit, and turned it off. Restarted after 15 mins. Only the check engine light came back on. We drove it back home. Just as we were entering the garage, the sequence happened again: Check Hybrid System warning followed by Red battery warning followed by car losing power. We had to push it back into the garage. Started it two days later and the check engine light was on. Check Hybrid System and red battery warnings did not come back on. Nearby Hyundai dealer's service said that they are not certified to work on Hybrid cars. Hyundai roadside assistance refused to tow it to the dealership that I brought from. So, I had to drive it to the next nearby Hyundai dealer service center who is one hour away. There, the technician ran diagnostics for the check engine light and got an error code: P01E0100. He said that Hyundai's website for running error codes is down. He reset the check engine light and no warnings came back upon restarting the car, so he sent me out. Dec 12: While driving in the residential neighborhood near my home, check hybrid system followed by check engine + red battery warnings came on; car sputtered and jerked and lost power; I did the mistake of turning left to try and bring the car back home; car lost power in the middle of the turn. Fortunately, there were no oncoming cars, so I could coast at 2mph and cross the road. This was extremely dangerous. I am concerned on two fronts: 1. The dealership service technician might not be able to get the warnings again, reset the check engine light, and send me back on my way. 2. If this issue occurs while driving in the interstate or while turning left at a busy signal, then this will likely result in an accident. I am concerned for my safety.
