Loss of power while trying to accelerate. RPM's were going up, but the vehicle was very sluggish. Nearly got rear ended as I had turned right on a red from a stop to merge onto a 55mph road. I could not get up to speed and had to pull to the side of the road and engage my hazard lights. I turned the vehicle off and let it sit for a few minutes, then turned it back on and the issue went away. No lights/warnings or sounds were associated with the problem. First time driving the car today. Weather is mid 70's and overcast.

The contact owns a 2025 Hyundai Santa Cruz. The contact stated that while driving at various speeds at night on several occasions, the headlights were dim and created a shadow across the roadway. The vehicle was taken to a dealer on multiple occasions. The dealer was initially unable to duplicate the failure but later diagnosed that the driver-side headlight bulb needed to be replaced. The vehicle was repaired, but the failure persisted. The vehicle was taken back to the same dealer on several occasions. The dealer ultimately deemed the headlight performance normal. The manufacturer was not notified of the failure. The failure mileage was approximately 200.

Making a left turn against oncoming traffic into a convenience store parking lot. There was a car in the driveway waiting to exit the convenience store parking lot. As I crossed the oncoming traffic lane the crash avoidance light on the dash came on and the brakes locked up nearly causing me to be broadsided by the oncoming traffic. An obvious malfunction of the crash avoidance system. I contacted the dealer and reported the issue. They advised my software was up to date and it was probably a ghost reading by the camera and software. No further action taken by the dealer.

Make: Hyundai • Model: Santa Cruz • Year: 2025 • Trim: Limited • Mileage: 2600 miles • Date of Purchase: July 2025 Description of the Problem: I am reporting a safety issue with the Forward Attention Warning (FAW) system on my 2025 Hyundai Santa Cruz Limited, which unexpectedly disables Smart Cruise Control (SCC) during highway driving. The FAW system, which uses an in-cabin camera to monitor driver attentiveness, frequently misinterprets normal driving behavior—such as wearing polarized sunglasses or holding the steering wheel at the 12 o’clock position—as inattention. This causes SCC to deactivate abruptly, resulting in sudden speed changes that create a safety hazard, particularly at highway speeds (e.g., 65–70 mph). The issue occurs multiple times per drive, especially when wearing sunglasses, and persists even after attempting to disable FAW in the vehicle’s settings (Settings > Vehicle > Driver Assistance > Driver Attention Warning > Off). For example, while driving on [XXX], SCC deactivated without warning due to FAW detecting my sunglasses, causing the vehicle to slow unexpectedly and requiring immediate manual intervention to maintain speed. This has happened regularly, creating a risk of rear-end collisions or driver distraction. I contacted my Hyundai dealership and they stated that no software fix is available and the system is “working as designed.” Hyundai’s Technical Service Bulletin (TSB 25-GI-001H) acknowledges FAW issues with sunglasses and hand position but offers no solution. I also contacted Hyundai Customer Service (1-800-633-5151), but they provided no resolution. This issue is widely reported by other 2025 Hyundai owners (e.g., Tucson, Santa Fe) in online forums INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
