Automatic Emergency Braking problems of the 2026 Hyundai Santa Fe

"what component malfunctioned. . . ?" - electrical system (suspected) "how was safety put at risk?" - we were unaware if the dashboard instruments were reading correctly. We also couldn't lock/unlock the doors or open/close the windows. The tailgate would also not open. "has problem been reproduced?" - not yet - plan to have the service center inspect. "has vehicle been inspected by the manufacturer?" - no "were there warning messages or symptoms?" - yes, when the issue occurred. The vehicle reported 13 warnings/alerts. Happened for the first time on 5/2/2026 general description: while the vehicle is parked or idling after sitting for a period of time, the dashboard suddenly displays approximately 13 warning alerts simultaneously, including a message stating "check emergency stopping function" among others. During this condition, multiple vehicle systems become inoperative, including: - power windows - could not open/close - door locks - could not lock/unlock - tailgate operation - could not open (it was closed) the vehicle appears to experience a system-wide electronic failure affecting both body controls and safety systems. The condition is intermittent but has occurred multiple times. Restarting the vehicle does not immediately resolve the issue. After driving for a period of time, the vehicle eventually returns to normal operation. This is a safety concern because: - critical safety systems (automatic emergency braking / driver assist features) are (potentially) disabled - basic vehicle functions (locks/windows) are unavailable. This is a concern if the door can't be opened and one needed to exit through the window in an emergency. - the failure occurs without warning and cannot be reliably reproduced on demand this appears to be a broader electrical or communication system failure rather than a single component issue.
