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.
full bulletin at NHTSA ↗Some vehicles may exhibit difficulty starting in cold weather. This bulletin provides the procedure to perform an inspection on the starter magnetic switch for potential freezing and, if necessary, replace the starter magnetic switch (solenoid) assembly.
full bulletin at NHTSA ↗Some vehicles may exhibit a loss of connectivity or interruptions in the middle of using Bluelink functions. 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 Konas report a spectrum of electrical failures, with complete power loss being the most consistent complaint. Multiple owners describe all electrical systems cutting out for 1-3 seconds while driving—headlights, dashboard instruments, infotainment, and exterior lighting all go dark simultaneously, though the engine continues running. This happens repeatedly over months, occurring in daylight and at night. Dealers cannot replicate the issue despite extended test drives and multiple visits; no fault codes register. One owner lost headlights at 40 mph at night, creating a serious safety hazard.
Battery failures are epidemic, striking vehicles with under 1,000 miles. Owners report waking to completely dead batteries with no prior warning from Bluelink or onboard systems. One owner's battery drained rapidly immediately after a Theft Prevention system software update, requiring replacement along with terminals and wiring harnesses.
Infotainment screens glitch and flicker, becoming increasingly static-filled and eventually going blank—issues sometimes similar to defects Hyundai acknowledged in other 2024 models. One owner also reported Lane Assist preventing the vehicle from turning left, requiring excessive steering force to override.
Key fob failures, starter refusals, and anomalous gauge behavior (miles-to-zero readings jumping rapidly, AC lights staying on when the car is off) compound the reliability picture. A recall for electrical issues exists but parts remain unavailable.

The dashboard lights, HUD and exterior lights all have been turning off for 4-5 seconds every 6-8 weeks for the last 14-15 months. The brake and accelerometer remain active but because of the situation it presents every time, all that can be done is stray straight and try to look for a safe lane change.
