My 2024 Hyundai Santa Fe (VIN: [XXX] ) was manufactured on March 14, 2024, in [XXX] . The vehicle is currently experiencing dual-clutch transmission (8DCT) juddering, shuddering, and extreme hesitation when trying to accelerate from a complete stop at traffic lights and intersections. This creates a severe lag in acceleration, leaving the vehicle dangerously exposed to oncoming traffic. This component failure directly mirrors the mechanical hazards outlined in NHTSA Safety Recall 263. Because my manufacturing date falls just outside the official recall window, this vehicle has not received a formal recall remedy, yet it actively exhibits the identical, dangerous powertrain defects, suggesting the recall's production scope may be too narrow. Furthermore, in November 2024, the vehicle suffered a catastrophic safety failure where it completely lost all propulsion power for approximately 30 seconds while moving through the middle of a live intersection. Most recently, on XXX, right after being released from an extended 38-day service stay at an authorized dealership, the electronic infotainment displayed an active warning screen stating the car should be shifted to park while the vehicle shifter was physically and securely locked in Park. Time-stamped video evidence of this active transmission/braking sensor failure has been captured and preserved. The vehicle remains an active, uncorrected threat to my physical safety on the road.

We have had several transmission issues with this vehicle for over a year. On March 5th we dropped the car off for an oil leak, a malfunctioning middle row seat belt, and an on going transmission clunk and roll. The dealer repaired the oil leak, replaced the seat belt, (damaged the interior of the vehicle while doing so, then denied it) and said they were unable to replicate the transmission problem. The car went back to the dealer again on March 26 for the transmission clunk and roll. They kept it for 8 weeks, and said they couldn’t replicate the issue. I have confirmation that they didn’t even start the vehicle for 4 weeks. We picked up the Vehicle on May 22, and the issue persists. Yesterday, when pulling out of a gas station, the vehicle accelerated on its own until I intervened stepping on the brake pedal. When I typed in the issue to Google, I was made aware that the vehicle now has a front seat belt safety recall from April 6, which the dealer didn’t even advise us on or offer to repair. I am finding out about this on an interstate family drive and we are of course terrified of driving our vehicle now, based on the unintended accessories and now faulty front seat seat belts. I have asked Hyundai serval times for a buy back which they have refused. Corporate has asked us to bring the car back to the dealer this week, and we are about to sign papers with a lemon law lawyer tomorrow. I wanted to at least file this complaint so that it is in writing should something happen to us in our travels this week. This has all been so unacceptable with Hyundai. We bought this car new and it is paid off.

The vehicle has experienced repeated transmission-related failures beginning at approximately 5,000 miles. The dashboard warning “Transmission System Error – Check Transmission Oil Immediately” first appeared while driving and was accompanied by sudden loss of power. When this occurs, the vehicle loses acceleration and drivability while in motion, creating a safety risk in traffic. The only way to temporarily clear the warning is to pull over, shut the vehicle off, and restart it. Photographs of the warning message were documented at approximately 6,738 miles on [XXX] and again at approximately 12,664 miles on [XXX]. The vehicle was returned to the selling dealer in Massachusetts multiple times for the same issue. During the first visit, the dealer drove the vehicle approximately 19 miles but stated they could not duplicate the problem. During the second visit on or about 3/25/2025, the dealer kept the vehicle for approximately six days while providing a loaner vehicle, but again stated they could not duplicate the condition. The vehicle was later inspected by another Hyundai dealer in New Hampshire on 8/19/2025 for the same dashboard warning and loss of power condition while driving. That dealer found the transmission fluid level below specification but stated they could not duplicate the warning message during inspection. Following that visit, the transmission warning did not reappear until [XXX], when the same “Transmission System Error – Check Transmission Oil Immediately” warning returned again while driving. On [XXX], the situation escalated into a possible rollaway event. While at an auto detailing facility, the vehicle was reportedly placed in Park with the engine running after being repositioned. The operator stated the vehicle indicated it was in Park. Moments later, after the operator exited the vehicle, the vehicle moved from its parked position and rolled into a building. The event was documented in writing by the detailing facility. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION A

I was trying to back up a few times and not being able to see some objects behind while looking at the rear view camera on my Hyundai Santa Fe 2024.

I bought the 2024 Santa Fe XRT Pro new off the lot Sept. 2024. Brought it in for 3 different recalls but the electronic system panel is new: The panel lit up with every warning sign it can convey: from the engine light to the coffee break, to the emergency warnings. This has happened twice; once a few weeks ago and again a few days ago. My car is back at the dealership for repair to the electronic panel. The first time, the dealership replaced the entire panel as it is still under warranty. It's at the shop again and I don't know what they will do this time. I would trade it in, but the trade-in value sucks.
