While the motor vehicle is in drive, the digital cluster will randomly reboot causing the digital cluster screen to go blank.

While traveling the following have happened multiple times. It has already been serviced by the dealership who corrected all pending recalls and then informed me they could not replicate the problem. It has now happened since the vehicle was returned to me. This morning while driving at freeway speeds. Multiple times Total HUD Failure: The Heads-Up Display (HUD) completely cuts power and turns off. Dashboard Cascade: The digital instrument cluster momentarily flashes almost every critical warning light simultaneously (including Brake, EPS, Charging, and Lane-Keep systems) before clearing itself. Powertrain Integrity: The engine and hybrid powertrain continue to run smoothly with no loss of propulsion or mechanical stuttering when the event occurs.

Driver alert system frequently comes on with blinking lights and on several occasions has slowed the vehicle while on cruise control even though both hands were on steering wheel. It appears that system is overly sensitive to glare from the sun. Hyundai should issue either a recall or software fix.

My instrument cluster goes completely blank while driving the vehicle. It will also have every light come on when it does come back on all of the check engine lights, and every other diagnosis light comes on. It continues to do this while driving. I have already had the safety recall done and it is still failing.

I am reporting a safety concern involving the rear turn signals on my Hyundai Tucson 2026. When the turn signal is activated, the signal is difficult to see from a vehicle that is very close behind the Tucson, particularly when the following vehicle is positioned directly behind or at certain angles. The location and/or visibility of the rear turn signal may make it difficult for a following driver to recognize that the Tucson is signaling a lane change or turn. I believe this presents a potential safety concern because a driver following closely may not receive a sufficiently clear visual indication of the vehicle's intended maneuver. I am requesting that NHTSA review whether the rear turn-signal design and visibility on this vehicle presents a safety-related defect and whether similar complaints have been reported for this model. I can provide additional information, photographs, videos, or details about the circumstances in which I observed the visibility problem if needed.

My cameras (front and back) show blue or green signal error screens intermittently. Dealer was not able to replicate, so basically told me to bring it back when it happens all the time. Google search told me that this is a widespread problem, some dealer somewhere must have been able to replicate the issue. Unable to use cameras to monitor for traffic and/or pedestrians. A few examples of when this has happened this morning: Backing out of my driveway, rear camera working, go to drive, front camera green screen. Parallel parking, rear and front cameras not working. Pulling into parking space, front goes to green screen about half way. Backing out of parking space, green screen.

Some Tucson (NX4, NX4A, NX4M), Tucson Hybrid (NX4 HEV), and Tucson Plug-In Hybrid (NX4 PHEV) vehicles may exhibit a 12-volt battery drain due to the passive entry feature of the Digital Key 2 premium causing repeated wakeup of the vehicle. This bulletin provides instructions to perform software updates for the Ultra-Wide Band (UWB) and Body Domain Control (BDC) modules.

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.

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.

The National Highway Traffic Safety Administration (NHTSA) has identified the presence of substandard and dangerous driver’s-side airbag inflators manufactured by Jilin Province Detiannuo Automobile Safety System Co., Ltd. (DTN). These inflators were not supplied, approved, or authorized by the vehicle manufacturers and have primarily been found in vehicles that previously experienced a crash and underwent airbag replacement using non-genuine parts. These dangerous inflators have ruptured during deployment, posing a serious risk of injury or death due to metal fragments entering the vehicle cabin. To date, Hyundai is aware of three people who have died while driving a Hyundai vehicle with one of these substandard replacement airbag inflators that deployed in what likely would have been a survivable crash. NHTSA has issued a public advisory urging vehicle owners and service professionals to have vehicles inspected if there is reason to believe that a non-genuine replacement airbag may have been installed. Vehicles with salvage or rebuilt titles, prior airbag deployments, or unknown repair histories may present a higher risk. NHTSA strongly cautions against self-inspection by vehicle owners and recommends inspection by trained technicians.

The National Highway Traffic Safety Administration (NHTSA) has issued an urgent safety advisory regarding dangerous, counterfeit driver‑side airbag inflators manufactured by Jilin Province Detiannuo Automobile Safety System Co., Ltd. (DTN), that have been identified in U.S. vehicles following prior crashes, theft, or non‑certified airbag replacements. These inflators are not approved for use, may rupture during deployment, and have caused serious injuries and fatalities. Please see attached announcement, provided by NHTSA, for more details.

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.
