2024 Hyundai Santa Fe: jerking or lurching

Filed Sep 9, 2026 · Brakes · NY

Despite having the DCT software recall repaired, today the parking brake disengaged after the car was idling for a few minutes at my son’s school. It lurched forward, startling me, and then I was alerted that the emergency parking brake deployed. The rollaway could have injured a child in the parking lot. No alerts or lights have been on prior. Additionally, after the rollaway incident, I was stopped at a red light, and my brakes depressed halfway. The last few weeks the acceleration from stop is difficult, and the brakes shudder and partially depress, especially when driving over a bump - feeling every minor flaw in the road rattling beneath my foot on the pedal. To also be mentioned - I have retained an attorney to pursue a Magnusson Moss cash & keep settlement on the car. From June - August 2026 the car was out of service, 4 repair orders, 2 dealerships, and a FSE I demanded finally found & diagnosed faulty O-rings causing the freon to leak and the AC to fail. The car also smelled strongly of fuel one full day, and the dash & steering wheel felt hot to the touch - but no defect was found or diagnosed.

What component or system failed or malfunctioned, and is it available for inspection upon request? Unsure, but likely transmission. I no longer own the vehicle, it is at Tom Ahl Hyundai in Lima, Ohio. How was your safety or the safety of others put at risk? When the vehicle was put in reverse, without pressing the gas the car would rapidly accelerate and jerk as if it was going to stall. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes, the dealership. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? The manufacturer was working on a fix but unable to figure out the issue, so I returned the car. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? No, no warning lights.

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 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.

When I first start my car for the day, I get an error message, which says transmission error get transmission checked immediately. I’m unable to put my car into gear and when I try to go forward the transmission acts as if insufficient transmission fluid and does not accelerate properly and go into gear. I went to a Hyundai dealer in October 2024!to get the car serviced. The Hyundai dealer flushed the transmission system For a while I no longer got the transmission error message on the dash. A few weeks later I had the transmission error again and the car would not go into gear. I took the car in for a second time to be serviced by Hyundai dealer They said that they reset the software. About a week later I got the transmission error message again, along with the difficulty of engage in the transmission. The workaround I had for this was to turn the car off and turn it back on again and that would get rid of the transmission error message until the next day. I plan to take my car in to a Hyundai dealer this week and report to them that I’ve been having this transmission error message almost daily for the last week. This problem makes the car feel unreliable, and it is a potential safety risk to not be able to accelerate and change gear when operating the vehicle. The car also lurches foreard slightly after parking and turning off thr ignition.

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.

After car is idle, when pressing the gas, the car instantly stops as if you have slammed on the break, feeling like you have driven into a brick wall. The intensity of the stop causes you to jerk aggressively in your seat. This has happened on more than one occasion. Without a seatbelt it would cause injury as well as the possibility of causing an accident with other vehicles. When this happens, there were no warning lights or messages shown to indicate an issue. The vehicle is currently at the dealership as of 9/20/2024, they are trying to replicate the issue however it has been more than 2 weeks, and they have not found a resolution. They have run diagnostics tests and there was nothing that indicated the issue with the vehicle. As of today, 10/9/2024, the issue has not been resolved and the vehicle remains in the dealers possession.
