Blind Spot Detection problems of the 2025 Hyundai Santa Fe

While I was driving on the highway, a diagnostic trouble code (dtc) related to the blind-spot safety system appeared.

Side view camera that displays blind spot area in dash screen cluster, screen intermittently shows just a green screen and not the blind spot.

Dear NHTSA team, my car was in a minor accident last. After that, the repair shop replaced my bumper and front camera. Don franklin somerset Hyundai performed a calibration on my new radar. They calibrated it six times, but there are still many issues with the hda driving system. 1. False dual-side warning when a vehicle is present only on the right side, the vehicle camera system incorrectly detects vehicles on both the left and right sides. In reality, there is no vehicle on the left side. In this scenario, both the radar warning and the camera detection are incorrect. 2. Wrong-side warning in some cases, when a vehicle approaches from the left rear, no warning is issued on the left side, while a warning is incorrectly displayed on the right side. In this scenario, both the radar warning and the camera detection are incorrect. 3. False warning during Smart driving while driving on the highway using the Smart driving function, when the vehicle is required to turn left or right, the system may generate a false dual-side warning. As a result, the vehicle aborts the intended left or right turn and continues driving in the center of the lane. In this scenario, both the radar warning and the camera detection are incorrect. 4. While driving manually (without hda engaged) or parking, the vehicle shows left-side or right-side collision warnings without clear cause. I reported these issues to Hyundai USA approximately three weeks ago. I was instructed to bring the vehicle to the dealership for inspection. However, during my recent visit, the dealership representative only reviewed the videos I provided and concluded that no issues were present, without conducting a physical inspection or test drive of the vehicle. Given the ongoing safety concerns and lack of proper diagnosis or resolution, I am submitting this complaint for your review and assistance. Thank you for your attention to this matter. Thanks, best regards, [xxx] [xxx] information redacted pursuant to the freedom of information act (foia), 5.

I own a 2025 Hyundai Santa Fe that was purchased on 08/15/2025. The first malfunction occurred on 08/25/2025, only days after purchase, and the vehicle has experienced repeated safety-related issues since then. The vehicle has repeatedly displayed false forward collision warning alerts, blind spot warning failures, park/neutral errors, and intermittent disabling of safety features. The most serious incident occurred when the vehicle unexpectedly entered “limit 20 mph” mode while I was pulling into active traffic with my toddler in the vehicle, limiting acceleration and creating a safety risk. I have also experienced false collision alerts while parked and after the vehicle was shut off. The vehicle has been taken to the dealership multiple times for diagnosis and repair attempts. Some issues were duplicated by dealership personnel, while other visits were documented as “could not duplicate. ” a front ultrasonic sensor was replaced, but the vehicle continued experiencing safety-related concerns afterward. During the repair process, I was informed and observed that dealership personnel appeared limited in what repair actions could be taken after consulting Hyundai through their diagnostic system. I was also informed that Hyundai influenced what could be included on service reports and that dealership personnel were instructed to “print the book” rather than fully document observed concerns. I believe this may have affected repair efforts and documentation of ongoing issues. The vehicle has been out of service for extended periods and the issues continue despite repeated repair attempts. Due to the ongoing malfunctions and inconsistent operation of the safety systems, I no longer feel safe driving the vehicle because I am concerned it may not function properly during a real emergency situation. Attached are photos of various dashboard errors and warning messages that occurred during these incidents to document the alerts and malfunctions experienced.
