2024 Hyundai Santa Fe

Our vehicle does this all the time and has done so for almost two years. After starting the vehicle and then shifting to a gear, either drive or reverse. The vehicle does not always go into gear. When you take your foot off the brake to push on the accelerator, the vehicle will start to roll in the opposite direction if you are on a very small incline in the opposite direction. If you are on flat ground, the car will not move for a few seconds. If the incline is in the direction of your selected gear, you start rolling in that direction with no power from the transmission. In one to three seconds you get power to the transmission. This happens at any time of the day, from the very first start up, to anytime during the day when in use. If you stop to get gas and when you restart the vehicle it can happen. We have almost hit other cars and people several times from rolling backwards when we have drive selected because the transmission does not properly engage. Everytime it happens I say to the car, why are you doing this? The only reason we haven't hit anyone or another car is because I hit the brakes again very quickly once we start rolling backwards after we do not start going forward. Not sure if it is associated or not, but driving through the parking lot a few times in drive. We have lost all power to the transmission. You are driving along and without any visual indications or sounds, you just start slowing down. If you press on the gas more, it does nothing to increase the speed of the vehicle. It has only happened once to us on a road going 45 mph. The power came back after a few seconds.

2024 Hyundai Santa Fe VIN [XXX], June 2024 build, 62k miles. Vehicle experienced total loss of power and drive, matching NHTSA recall 24V-529 / 263 for DCT failure. Dealer is refusing to perform recall, refusing to provide diagnostic codes via email, and demanding title and all service records before any work. Dealer claims new engine needed but won’t provide proof. This is a safety defect and dealer is violating recall law."

I purchased a 2024 Hyundai Santa Fe SEL with 16,087 miles that has a the 8-speed Wet Dual-Clutch Transmission (DCT) stutters to catch gear properly while accelerating from low speeds and back to high, example driving onto a highway ramp and matching speeds with ongoing traffic). Unfortunately, there have been multiple fears and risk of safety where accidents almost occured due to the transmission not catching the engines rotational speed to exact, causing slow to no acceleration. This is very dangerous and unsafe to not be considered under investigation. This unresolved issue will deteriorate the clutch and transmission itself over time. HELP!

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.

The contact owns a 2024 Hyundai Santa Fe. The contact stated that while driving at various speeds, the vehicle jerked and shuddered and lost motive power. There was no warning light illuminated. The vehicle was taken to the dealer, where the contact was initially informed that the failure was not related to the transmission; however, the dealer later diagnosed the vehicle with transmission failure. The contact was informed that the transmission needed to be replaced. The transmission was replaced, and the contact was advised to pick up the vehicle; however, the failure recurred while driving. The vehicle was taken back to the dealer. The vehicle was not yet repaired. The contact's Attorney notified the manufacturer, who proposed an unsatisfactory settlement. The failure mileage was approximately 28,000.

We just brought this vehicle in for the ongoing transmission problem (previously reported to your agency after the car self-accelerated), as well as the missed seatbelt recall that was not addressed at the last dealership. I advised the service advisor that the seatbelt recall needed to be fixed. The service advisor contacted us several hours later to tell us that they were replacing the transmission. 10 days later we picked up the vehicle after the transmission replacement, and the service advisor told us they did not do the seatbelt repair, citing lack of parts and/or special order. I asked if this was a safety issue and if I should leave the vehicle with them for longer, but was told not to worry about it, and to bring the vehicle back at another time. Fast forward to today, and the vehicle is rolling forward when we start it. This is worse than the way it rolled forward before the transmission replacement. Coupled with the disregard for the seatbelt recall, I believe there is a serious safety issue with this vehicle. I have notified Hyundai Corporate, as well as our attorney, and will be contacting the dealership to drop the vehicle off. I have a video recording of the car rolling forward during startup, but it appears I cannot upload it here. I have forward that video to the above mentioned entities, and am happy to share it with your agency as well.

I have had my vehicle inspected twice for an intermittent issue with the rear driver's-side brake light. The brake light continues to go in and out even though the issue has not been identified during inspection. Multiple people have informed me that the brake light was not working, but when checked later, it was functioning again. Because the problem is intermittent, I am concerned that it has not been properly diagnosed. In addition, I have experienced ongoing transmission and drivability concerns. While stopped at traffic lights, the vehicle has occasionally accelerated unexpectedly or surged, and it can be difficult to shift into gear to proceed. I have also experienced hard shifting when moving from Park or Reverse into Drive. These symptoms continue to occur despite being told that no problems were found during inspection. I am requesting a more thorough diagnosis of both the brake light issue and the transmission/drivability concerns, as these problems are ongoing and may present a safety risk.

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.
