The transmission is the problem that caused the vehicle to downshift while driving and resulted is a sudden jerk and slowdown in speed. My safety was at risk as the car slowed down suddenly and almost caused the vehicle behind me to rear end my vehicle. But luckily the other driver was able to stop. I previously brought the vehicle to Hyundai service (12/12/24) and they indicated that they couldn-??t replicate the problem and there was no situation. The vehicle will be brought to the aforementioned service center again to check the situation (1/07/25). There were no warning the first time it happened, as mentioned earlier and after the second incident the car displayed the message that occurred the first time again which I have attached.

On December4th 2024 my car rolled forward into a barrier post. I stopped to get air in my tires and the Parking Allert went off as I got near the barrier post. I then parked my car. I left my car running and driver door partially opened. I dropped the valve cap between the spokes of the last tire being filled. So, I got into the car and backed up about three feet to get the cap. Parked the car got out and it rolled forward into the barrier post. I was completely out of the car but just by my driver door. I tried to get back in but it was too quick. Subsequently, I drove to work to let my supervisor know i would need time to go to the dealership. I was concerned air bags would deploy since that didnt happen. Also because the car didnt stop on its own felt the integrity of systems were questionable. So, I repeated the steps at work like the incident. Except, I stayed in the car. The car beeped and the dash said Shift to P when my door was open and placing in drive and reverse. I NEVER got any indications of such when the car hit the barrier. I found the two DTC's that showed on my Hyundai App were related to DTC U110387 and U110382. I had 99 miles on the car having purchased it with 15 miles on it. The original date of these DTCs is Aug 27th, 2024, with a last reported Aug 30, 2024. I see recalls 24V529000 and 24V246000. I don't know if they are related. but this has to be addressed. My car is at the dealership being repaired and my insurance rate will no doubt go up and the value of my car down. This isnt right.

My vehicle was in for repairs at both a collision shop and a dealership following a minor accident. When I got the vehicle back, I found that the seat controls were not working, preventing me from moving the seat backward or forward. During a test drive, the car lost power despite the gas pedal being fully pressed; it wouldn't accelerate and then suddenly jerked forward. This could have caused an accident if I had been on a busy highway. Further testing revealed an abnormal noise at 1500 RPM in multiple gears. The vehicle has been towed back to the dealership, but there's no word yet on when it will be fixed. Hyundai has been contacted multiple times, as the car has been awaiting parts and undergoing repairs for over four months. They don't seem to be taking these safety issues seriously nor helpful in resolving the issue.

We purchased our '24 Santa Fe hybrid on 9/18/24 new with no problems. On 10/8/24, about three weeks later, I was stopped at a stoplight after exiting the freeway. When the light turned green, I accelerated and felt a clunk, then the car would not accelerate past about 30 mph. Several warning lights came up on the dash. I could hear the engine revving, but it felt like it wouldn't go into the next gear. I thought I could make it to the dealership, which was only a few miles away. But at the next stoplight, I was stopped in a turn lane, and when I pushed on the gas nothing happened. I tried shifting back and forth from park and restarting the car, but nothing helped. The car would not accelerate at all. CHP shut down the intersection and helped me push the car to the side of the road, where I waited for a tow truck. The car was towed to Folsom Lake Hyundai, where it was purchased. Warning lights said "Check hybrid system, " "Transmission control system" and "Driver assistance system." The app listed these codes under POWERTRAIN issues: DTC P198500, DTC P178400. We picked up the car from the service center on 10/11/24. They said a wire came loose from the oil pump, so they reattached it according to factory direction and it's fixed. 5 days later, on 10/16/24, the car stalled again. This time on the freeway. I entered the freeway and accelerated, then felt a similar clunk and got the same warning lights. This time, the car would not accelerate at all. I stopped on the side of the freeway and was towed to Folsom Lake Hyundai again. It took almost 2 weeks to repair, but they said the same thing happened again. The same wire came loose, causing the car to stall. Their solution was to reattach it again and wish me luck. They said maybe I drove on a bumpy road, but there's nothing else they can do but reattach it and get it out the door. I do not feel like this is an adequate repair and we are now worried that the car will stall again in the coming days.

At approximately 1500 miles on the odometer, I started to receive a warning roughly one out of every 3 times I started my 2024 HYUNDAI SANTA FE. The warning would flash red and read "Transmission System Error!, Check transmission oil immediately" and would refuse to move out of first gear, revving to approximately 5000 RPMs. The onboard vehicle diagnostic system reads all systems NORMAL when performed and this error requires a vehicle restart to clear.

Brand new vehicle purchased through Clement Hyundai. Within a couple hundred miles, multiple times vehicle goes into neutral on its own while driving. Have to stop the vehicle and turn off engine to try to get it into drive to get off the road. Takes several attempts to get into drive. Major safety hazard! Repaired once by Jefferson City Hyundai. Same problem happening again. Car not drivable as it is a safety concern. Have found multiple online forums wherein people are having the exact same problem.

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.

On Wednesday, August 28, 2024, I was driving southbound on Interstate 95 in Florida at 72 miles per hour in the left lane. As I approached my exit, I attempted to switch to the middle lane when, suddenly, the car stalled. Pressing the gas pedal had no effect, and the car rapidly lost speed. Fortunately, the drivers around me, who were all traveling at speeds exceeding 70 miles per hour, slowed down, allowing me to safely pull over onto the shoulder of the highway. The following morning, I contacted the dealer and drove the car in for inspection. I was shocked to learn that the car, which is a brand-new lease with only 1,500 miles and less than two months old, requires a new transmission. After this terrifying experience, I no longer feel safe driving this vehicle, even after the transmission is replaced. This is my first Hyundai, and in 25 years of leasing cars, ranging from Honda to Maserati, I have never encountered an issue like this. The whole point of leasing a car is to avoid situations like this one. This is completely unacceptable.

Transmission failure. Problem confirmed by dealership on 7/22. Problem arose on 7/20 with car jumping forward abrublty and started making a clicking noise and hesitating. Did not learn about recall until I logged into my insurance company website to pay my insurance and it listed a recall on my Santa Fe on 7/20. Dropped car off at dealership on 7/22 and was told later that day it would need a new transmission and the dealership was told by Hyundai to give me a loaner car until Hyundai decided what to do about my car. I filed a claim on 7/23 with Hyundai about doing a buy back. I was told I would receive a call in 2-3 business days but have yet to receive one. I called Hyundai on 7/31 and was told my case manager had left a voice mail for me on 7/29 but I have no vm or missed call. I was given my case managers direct phone number and left a vm. Today is 8/1 and my 2024 Santa Fe Calligraphy that I bought on 6/28 and drove for only 3 weeks is sitting in the dealerships parking lot and per dealership, on 7/31 they are still waiting to hear from HYUNDAI. It has 1300 miles on it and luckily I did not get stranded 400 miles away while on vacation. I am very upset that no one contacted me or when problems started to occur with this vehicle, nothing was done and the vehicles were still being sold to the public
