Warnings problems of the 2022 Hyundai Santa Fe

Vehicle began to display front collision avoidance system error/ radar blocked. This also disabled the 'Smart' cruise control features. This happened any time the cruise control was engaged and we encountered traffic. The unit was in the dealer's service department for a week, and the front radar module was replaced and reprogrammed under warranty.

Vehicle purchased 9/1/24 from courtesy Hyundai of tampa. Dealership failed to file registration/tags until 10/4/24. 7/12/vehicle experienced involuntary acceleration and braking, resulting in impact with my mother’s home. 7/16/dealer issued written report stating vehicle was operating normally and documented a recall-related display/audio/camera software update. 8/14/Hyundai engineering inspection performed without my knowledge. No report has ever been released. 8/27/Hyundai issued corporate denial, blaming driver error and stating braking/acceleration systems were normal. 12/5/second involuntary braking incident at highway speed on I-275. Five uncommanded braking events over ~20 miles. Service manager stated failure was due to sensor/camera malfunction and instructed that the vehicle should not be driven and to tow immediately. Despite this, the vehicle had been released into roadway operation. VIN lookup shows an open, unrepaired federal recall (24v879000 / recall 271) for the rearview camera system, marked recall incomplete, despite the dealer’s documentation that recall-related camera/software work was completed on 7/16/25. Bbb auto line denied my claim only because the vehicle was outside florida lemon law eligibility. No safety determination was made. Hyundai released no engineering, sensor, or camera data despite an engineering inspection. This vehicle has experienced repeated involuntary braking and acceleration at highway speed, involving braking, camera, and automatic emergency braking systems, creating a serious risk of loss of control, collision, injury, or death. Despite repeated failures, contradictory diagnostics, withheld engineering data, and an open federal recall, the vehicle was released back into public roadway operation. I request that NHTSA formally investigate this safety defect.

Front radar system continues to not work without having damaged caused. Makes cruise control not work. Forward collision not work, etc.

On three separate occasions over 18 months, the car has entered into front collision avoidance mode by unexpectedly swerving the vehicle and braking. Twice I was on the tollway doing 70 mph on a 4 lane expressway and I drove in between two tractor/trailer semis. When I reached mid point, the car braked heavy on it's own and swerved first the right, then to left. In each incident, not only did it scare the hell out of me, I thanked god I avoided a major accident from crashing into the trucks and or being hit from behind. In the third incident (date of this complaint) I was driving over train tracks on two lane road at about 35-40 mph, there were yellow black traffic barriers dividing the narrow roadway at the tracks and the car suddenly braked and swerved, nearly getting me rear ended and putting me down into the culvert around the tracks. In each incident it was difficult to take control of the car back from the collision avoidance.

First the check engine light was on and the vehicle was vibrating really bad and making a loud sound. Took it to the Hyundai dealership which claimed to repair the issue. While on my home from the dealership ( Hyundai of slidell), which was almost hours away, the vehicle lost power while driving. Later, multiple lights were illuminated on the dashboard including the epb, auto hold, forward collision, blind spot, check engine, and oil light. The vehicle is currently back at the dealership. Hyundai has been notified numerous times about the issue. This is a safety issue that needs to be resolved. Although there are no current recalls for this issue everything im experiencing with my vehicle are the same issues reported in previous recalls.
