Some Palisade (LX2), Tucson (NX4), and Tucson Hybrid (NX4 HEV) vehicles may experience battery drain due to continuous operation of the cooling fan after vehicle ignition has been turned off, potentially resulting in a no-start condition. The continuous cooling fan operation is caused by a stuck relay in the engine room PCB block. This bulletin provides instructions to replace the engine room PCB block to ensure the proper operation of the cooling fan.

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 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.

The failure pattern owners describe
Water intrusion is a recurring problem. Owners report passenger-side flooding from windshield and firewall leaks on 2024 Tucsons, sometimes undetected for months after purchase. Hyundai issued a service bulletin (11/02/23) directing dealers to apply sealant, but water leak specialists note windshield repairs typically require a glass company. One dealer confirmed eight vehicles with this issue.
Electrical gremlins are persistent. Owners report random warning chimes without any dashboard message or visible alert—one driver had seatbelt buckles replaced, but the chime recurred. Instrument clusters have gone black and caused stalls at highway speeds. Complete electrical shorts have also occurred at delivery.
Safety systems are failing. Both horns failed before 15,000 miles on one vehicle (horns require bumper removal to access). Backup and front cameras stopped working after amplifier service at a dealership, and the dealer couldn't diagnose it after two visits. One vehicle experienced sudden full-throttle acceleration during a slow parking maneuver, jumping a curb and hitting a tree; the dealer refused to check the event data recorder.
Most serious: Hyundai Recall #290 (NHTSA 25V893) addresses water intrusion in the tow hitch wiring harness control module, which can fail stop lamps or cause electrical fires. As of February 2026, Hyundai stated no repair exists, no parts are available, and no timeline is set—while advising owners to keep driving the vehicle.

Both horns failed in less than 15k miles. Any time spent on the internet shows this is a known issue. Reporting as a safety problem as you will not know they are gone until you need them to warn another car or person and you have no sound. Luckily I was not speeding and paying attention but the kid who rode a bike in front of me when my horns failed - wondered right out. I stopped just short of…
See attached document for complaint.
the entire computer system shorted out throughout the entire car. It did not let me select above all of what it affected. The entire car malfunction due to the dealer not doing predelivery inspection. They have the vehicle and have not given me a written explanation or reports as to what happened to cause this. This vehicle was defective and dangerous and should not have been sold.
