2023 Hyundai Santa Fe Hybrid

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.

On highway, emergency braking enacted. I pulled to side the of the road to turn engine off and restart car. When I did, I could not put the car in gear. I have had other similar incidents happen with this vehicle. After about an hour of waiting for roadside assistance and having NYS troopers come help, the car dash lit up and I was then able to put car in Drive. When I talked to dealership and said that I got a diagnostic message on my screen to have transmission component checked TODAY ('today' was in all CAPS on the screen), they said they could not get me in. Then when I said, "I'm supposed to just drive around hoping my car doesn't break down again?" She said, "I'll cross my fingers for you." Are you kidding me!? My safety is at risk is this what a major dealership's answer is to the car's issue?

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

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 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.

vehicle fails to accelerate, engine is “sputtering” and making a rattling sound and battery is draining to nothing on the freeway driving at normal speeds. vehicle is lurching and engine does not appear to be shifting as it should - car losing power and failing to accelerate despite being full of gas. transmission doesn’t feel like it is shifting properly. vehicle only has 8000 miles.
