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 navigation and head unit software changes introduced in the 2026 1st Navigation Map and Software Update. The changes may vary depending on vehicle type, model, and navigation system. Refer to the 2026 1st Navigation Map and Software Update Key Improvements and Additional Improvements tables in this TSB for a list of specific changes. The software can be downloaded via Navigation Updater (NAU) and updated by USB.

This may be due to an occasional disconnection on Verizon’s communication network. Follow the procedures in this bulletin to verify Bluelink Data Communication Unit (DCU) network connection and if needed, reset the DCU in Dealer Mode to resolve the connection.

Owners of 2024 Hyundai Santa Fe models are documenting widespread electrical failures affecting safety-critical systems. The digital instrument cluster intermittently blacks out, flickers, or displays static while driving, leaving drivers without a speedometer, warning lights, or vehicle status information. One owner entering a school zone lost all speed indication. When the cluster fails, the heads-up display also goes dark. These blackouts happen unpredictably within the first week to first month of ownership, and at least one occurred around 1,300 miles.
Multiple owners report dealerships acknowledging the problem is common across all Hyundai digital display models, yet no permanent fix exists—software updates attempted on at least one vehicle only provided temporary relief before symptoms returned.
Beyond the cluster, owners describe the Forward Attention Warning camera system triggering false inattention alerts when wearing polarized sunglasses or adjusting the visor, disabling cruise control without recourse. Infotainment screens flicker and glitch; audio loops and continues playing after shutdown. One owner's battery-to-fuse box wiring melted, another's Body Control Module failed entirely at 12,000 miles (vehicle rolled backward in Park), and ignition start failures have persisted through dealership service attempts. Hybrid battery connections lie exposed under the chassis, and one owner's $5,000 repair resulted from road debris striking it at 27 mph.

Synthesized from 19 NHTSA owner complaints — unverified consumer allegations, summarized for patterns. The verbatim filings appear below.
I was riding on a suburban street and ran over a branch I did not see due to rain and darkness. I went back and looked at the incident and the branch did not seem like it was that big but I quickly lost power and my car stalled and I could not get it restarted. I later found out that that branch took out my hybrid battery connection under the car which rendered the car useless. It is a 5000 fix.…
