2023 Hyundai Santa Fe Hybrid

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

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.

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.

On 8/14/23/ I got the first oil change for my new car at the dealer. On 8/15/23 as I cruised at 65mph on a crowded Detroit expressway, I pushed further on the accelerator to get away from an aggressive driver on my tail. Nothing happened; The car engine shut down. No warning, no lights, no beeping, no alarm, no dash screen message. Dead engine in the middle lane with cars all around. After i miraculously made it to the shoulder of the freeway, The engine light and oil light came on. Not before, only after the car died. The dipstick indicated The car was out of oil. Unbeknownst to me the parts used to change the oil the previous day were defective. The oil had leaked out over the course of the day and over night. (I later discovered my driveway full of oil). THE PROBLEM, additional to the defective parts is the fact that I HAD NO WARNING THAT THE ENGINE SHUT DOWN WAS IMMINENT. I HAD NO WARNING THAT THE CAR HAD NO OIL. I came close to getting killed that day, and still have nightmares. Had i known the car was oil-less, I would not have driven it. This is a car that beeps and pushes and tells one how to drive at every juncture. It tells low gas, low tire pressure, etc. WHY WOULD IT NOT WARN ABOUT THE LOW OIL OR THE IMMINENT ENGINE SHUTDOWN??? I was told the car has a “FAILSAFE” feature for the oil. HOW SAFE IS A FAILSAFE IF THE DRIVER GETS KILLED WHILE THE CAR ENGINE PROTECTS ITSELF???

On nine separate occasions between mid-June 2023 (mileage appx. 600) and July 21, 2023 (mileage 1994), my vehicle lost power (decrease or loss of power and/or hesitated, sputtered, or stalled) when I was accelerating from a stop or slow speed. During these times, I have noticed that the air conditioner starts blowing only warm air. The only way to correct the issue has been to turn off the engine and then restart it. No error codes have ever been generated, and only twice did warning lights come on (engine oil light and battery light). I will upload my documentation file (to date) with the specifics of what happened along with dates and mileages this has happened. This happened one time on the freeway; I had to pull over to the side to stop/restart my engine. It was very unsafe and put my family at risk. This is a significant safety issue, and I do not feel comfortable driving because if I pull out into traffic and experience this loss of power, I could easily get hit by oncoming traffic. The vehicle has been at the Hyundai dealer since July 5, 2023 (three weeks tomorrow), and it is still there. They had not been able to replicate the problem. I went to pick up the vehicle on July 21, 2023, and as soon as I left the parking lot, the problem happened. I did a U-turn to come back to the dealer, and the vehicle lost all power. I had the vehicle in reverse, and there seemed to be no engagement of the transmission. Even with the gas pedal pushed all the way to the floor, there was no engine revving and no movement of the vehicle. The Hyundai technician and service advisor came to see the issue firsthand (since they had not been able to replicate it). The issue was only resolved when the vehicle engine was turned off and restarted. The vehicle remains at the dealer for further testing. Yes, I will gladly make my vehicle available for inspection upon request.

Check engine light and HEV warning light come on and vehicle looses all power. It has been confirmed by myrtle beach Hyundai also they tried fixing the problem gave me back car supposedly fixed just to have same problem within 24 hours.The problem started later part of April and is still ongoing vehicle has been towed 3 times so far.My concern is what happens if I loose all power while driving.

This is related to Complaint Number 11526621 filed June 13, '23. Today I experienced the same issue described in my previous complaint but under different circumstances. I was at an intersection of two 2-lane highways, one going east-west and the other going north-south, and was facing oncoming traffic as I waited for a gap in the oncoming traffic that would allow me to make the left turn. Once a gap appeared (perhaps 4 or 5 car lengths long), I pressed the accelerator to turn left but there was zero propulsion for about 2 seconds. I was simply stalled in the path of the oncoming traffic. At the end of the 2 second delay, as the vehicle transitioned from EV (electric) to internal combustion (gasoline) mode of propulsion, my vehicle GRADUALLY accelerated just enough to allow me to complete the turn; however, I came very close to being broadsided by the oncoming traffic. This is a dangerous fault of the 2023 Hyundai Santa Fe Hybrid vehicle and needs to be addressed asap! There is obviously something wrong with the EV/internal combustion synchronization/communication causing the momentary loss of power!
