What 131 owners told NHTSA about the 2024 Hyundai Santa Fe Hybrid Hev

I was merging onto the highway and the acceleration stopped working and the vehicle would not go more than 25 mph. Had to restart car in shoulder, isue seemed to self correct but then it happened 10 minutes later stranding me in between the highway and exit ramp. This was a huge safety issue and myself and others lives were at risk. I am bringing the vehicle in for inspection but this seems to be a recurring hyundai issue. There were no warnings that came on. The auto mode on the dash went from green to an amber color. When i restarted the vehicle nothing changed. After the second time it occurred a check engine light came on.

When the car is off and in park and you go to turn on the car on by pressing the brake and power button button, the electrical system doesn't register and wont turn the ignition on and the brake gets stuck and you cant start the car. The same thing happens when the cars auto ignition is turned off at a red light then you press the gas to go but it doesnt show the gear is in drive and the ignition turns off and wont turn back on. The major safety concern is when this happens at a red light or in traffic and my car stalls and I am at risk of getting rear ended. I have taken the car to the dealership twice now for the same issue. The first time they claimed it was fixed but it wasnt and now it is at the dealership again for the same issue and I have not received any remedy yet. There is no warning to this issue it happens out of know where and is extremely dangerous. The issue has been going on for several months.

When making a right turn from a complete stop, the vehicle intermittently exhibits noticeable hesitation and reduced acceleration compared to normal straight-line launches. This has occurred approximately 5–6 times. The delay in power delivery creates an unsafe condition when merging from on-ramps into higher-speed traffic, as the vehicle does not accelerate as expected. This mismatch between expected and actual acceleration can lead to misjudgment of traffic gaps. No warning lights or diagnostic messages have appeared. The issue appears intermittently and specifically during right-turn launches from a stop.

Vehicle was not driven for 2 days. The check engine light is one and says "active airflap issue" the flaps appear to be open when a/c is on and closed when vehicle is off. There is no debri or anything arount the air flaps. This could cause potential overheating and should not happen in a years time. We travel for my husband's job and this could be very dangerous. We thought we were buying a new RELIABLE vehicle.

this truck has repeatedly gone in for service over 6 times for multiple issues. The worst issue which they cannot fix is the vehicle going into limp mode while driving . Loosing all acceleration then racing on its own . This is a very dangerous problem when on the highway.hyundai service keeps telling me that the diagnostic is not showing a problem. This can be caused due to many things including transmission electrical or computer problems. I have reported to the office of consumer affairs and they claim hyundai dealership in myrtle beach has not responded to them. meanwhile i am driving in a very scary situation not knowing when this will occur. This happens at random times with no warning. This has happened at least 10 times in the last few months.

Vehicle has about 4k miles. Received “transmission system error, check transmission oil immediately”. The vehicle barely drives. Has a hard time changing gears. Hyundai says there are no recalls and are not being helpful in getting help. They say everything is fine but it is clearly not working. Brand new vehicle and cannot get it fixed.

Transmission. Less than 6 months of buying the vehicle, Hyundai replaced the transmission and now I’m still having problems..it revved up to 2.3 rpms but didn’t change gears then jerks into gear..not everyday but atleast once a week. I’m waiting now on the dealership to look at my car now..but they’re dragging their feet.

The issue I have is related to the transmission and exactly what is outlined in the Hyundai Santa Fe recall 236. My car was not included in that recall though. But the problem is exactly the same.

While the car was in park, we used the auto start feature to get the A/C going as we walked to the car. We heard a loud popping sound then shut the car off. My husband looked under the hood to look around for what could have made the noise and asked me to start the car. When I did, the car started moving forward on it's own with my husband standing in front of it and our 3 kids in the car to witness, which was scary but fortunately nobody was hurt and we were parking and not in traffic. I was able to use the brakes to get it to stop moving. We drove it about a mile and when attempting to put it in park, it prompted me to use the parking break because the Park function wasn't available. When I attempted to put it in drive, it flashed through all of the gears before saying, "Shift gear malfunction" then "Service Immediately." I used the parking break and was able to turn the car off after a few attempts of it going into accessory mode. This was 30 days after purchasing the car brand new with 10 miles on it leaving the lot. We found the safety recall posted online on July 8th, but were not informed by the dealership.The dealership didn't have a loaner to provide, so we had to pay out of pocket for a rental car for 7 weeks before they finally provided a loaner for the final week before it was repaired 60 days later. We were told there was no ETA on when the parts would be received, but we had to call the Service Advisor or go in person because they were not responsive by phone or email. The transmission, software and battery were replaced. We are pursuing a buyback. No consumer of a new vehicle should be expected to pay their car payment for a new vehicle while also renting a car. Our reimbursement from Hyundai's Corporate office is still pending. The official safety recall notices came within the last week of the repairs being completed.

Shuddering/shaking when driving. Whether or not when accelerating. Turn vehicle on and it jolted and died but would start up again after a few minutes.
