Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering electrical on this vehicle — documented repair instructions, service campaigns, or warranty extensions sent to dealers. A TSB isn't a recall (it's not a free safety remedy), but it's the manufacturer acknowledging the issue and how to fix it.
This bulletin provides information related to the changes introduced in the 2025 1st Navigation Map and Software Update. The changes may vary depending on vehicle type, model, and navigation system as described in this TSB.
full bulletin at NHTSA ↗A software update is available for multiple vehicles equipped with either Display Audio 2.0V or the AVN 5th Gen Wide system.

The failure pattern owners describe
Owners of 2022 Hyundai Santa Fe identify a cluster of electrical failures affecting critical systems. Dashboard display outages occur intermittently, with one owner describing the screen going black for 10–15 minutes while driving—a safety hazard they reported to the dealer without resolution. Check engine lights appear repeatedly in multiple vehicles, sometimes without stored diagnostic codes; one owner was stranded on a highway when a fuel injector failed after being cleared by service. Engine control harness melting under the fuse box appears in at least two narratives with identical symptoms: loss of HVAC airflow, and dealers confirming they've seen this same defect in multiple 2022 Santa Fe units.
Horn systems fail repeatedly—one owner replaced theirs 4–5 times over two years. Child safety concerns emerge: a child locked inside with the key fob when the smart-key system failed to prevent locking, and rear-door auto-unlock function failing over 25% of the time, trapping passengers inside. Engine stalling occurs mid-drive with complete loss of electronic steering, braking, and hazard controls. Reverse camera systems fail to activate. One vehicle experienced an interior fire while parked, originating at the lower dash/BCM wiring junction. Battery drain issues prevent starting, even after replacement. One fuel injector failure led to complete engine replacement at four years old—unusual for this vehicle age.

Synthesized from 21 NHTSA owner complaints — unverified consumer allegations, summarized for patterns. The verbatim filings appear below.
What owners are reporting 2 most recent
Engine control harness with under fuse box due to melted fuse box. This caused my blower motor and relay to go bad. No air flow currently in car due to control harness. Dealership stated that there has been several Sante Fe that has came in this year with the same issue.
The integrated thermal monitor is stuck. When I took it to Ken Vance Hyundai today, they said it is a common issue and if left unfixed. It would blow the engine.
