On XXX, while traveling southbound on [XXX], the vehicle crossed the intersection of [XXX]. Approximately 50 feet past the intersection, the vehicle experienced a sudden, complete loss of motive power and total electrical system failure without any prior warning. The entire instrument cluster and infotainment system went completely dark. All electrical controls failed immediately, including the hazard warning flashers, which could not be illuminated to warn oncoming traffic. Because the vehicle utilizes an electronic gear selector, the transmission could not be shifted into Park (P) or Neutral (N). I was forced to bring the vehicle to a stop directly in the active roadway lane and manually hold down the mechanical brake pedal to prevent rollaway. This sudden vehicle blackout and total loss of propulsion in active traffic created an immediate life-safety hazard, stranding the unlit vehicle in a live traffic lane without emergency signals. The vehicle had to be towed via tow truck to dealer. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Our 2026 Hyundai Palisade has experienced repeated dangerous electrical failures while driving. XXX All instrument displays went completely black while driving. The engine continued running. Gateway Hyundai in Fargo, ND, checked the vehicle but verbally reported finding no diagnostic codes. XXX While driving on the highway at night, the interior displays and exterior lights repeatedly flickered off and on. XXX The vehicle unexpectedly lost power and shut down at highway speed, requiring a tow to Don Bessette Hyundai in [XXX]. The dealership documented 36 stored diagnostic trouble codes, primarily communication faults. The codes were cleared, and an ECM software update was performed. No confirmed cause was identified. XXX The instrument panel went completely black twice while driving, lasting approximately 10 minutes and 14 minutes. XXX While driving at night, the interior and exterior lights again flickered off and on. Approximately 30 minutes later, the instrument panel went black and the exterior lights dimmed. We pulled over, activated the hazard lights, and restarted the vehicle, but normal lighting did not return. We drove approximately 14 miles with hazard lights on to reach the nearest town. The lights eventually returned, but the instrument panel continued flickering, the front camera repeatedly reported being disabled, and driver-attention warnings appeared during the drive home. These failures continued after dealership service and a software update. We are concerned about another sudden loss of engine power, headlights, or critical driver information at highway speeds. These failures pose a serious safety risk to occupants and other motorists. We request that the federal safety agency investigate these electrical failures.

Vehicle purchased new in August 2026. Within 80 miles, it began experiencing a recurring electrical fault causing simultaneous warnings across the steering, braking, and driver-assistance systems (DTCs C28C586, C164286, C181486, C181483, logged via Hyundai's Bluelink diagnostic system). The fault has recurred at least 9 times between 80 and 1,121 miles despite three repair attempts (8/28/26, 9/8/26, 9/14/26), including one escalation to Hyundai's national TechLine (Case #2026091700002) referencing TSB 25-GI-016H. Each repair was declared successful, and the identical fault returned within days each time. During active occurrences, dashboard alerts have included "Check Driver Assistance System," "Check Rear Cross-Traffic Safety System," and simultaneous warnings for lane departure, forward collision, blind spot, and anti-lock braking systems. This represents a loss of reliable communication between safety-critical systems (steering assist, ABS, and driver-assistance) while driving, creating a risk of degraded steering or braking response without warning. Manufacturer has declined to repurchase or replace the vehicle.

The instrument cluster automatically turns on (and stays on) when a car door or the trunk is opened without the car being started. This lead to the battery draining twice while packing and unpacking the car while on a recent camping trip. If I was not with another family that was able to jump my car, my family would have been stranded in the woods. The automatic wake up is considered a feature, but it can put people's safety in serious jeopardy by causing them to be stranded in remote areas. The trim level of this vehicle is marketed as the off-road package, but this feature makes using the vehicle in the manner it is marketed dangerous.

On September 15, 2026, my 2026 Hyundai Palisade Calligraphy would not start and could not be driven. AAA responded, tested the 12-volt battery, and advised me that it had a bad battery cell. The vehicle was towed to Larry H. Miller Southwest Hyundai Albuquerque for diagnosis and repair. A service representative later told me that a parasitic electrical drain or malfunctioning component may have depleted the battery, but I have not received a written diagnosis confirming the cause. As of September 28, the vehicle remains at the dealership and has not been repaired or returned to me. I have also experienced two seat-related safety concerns. The driver’s seat moves backward automatically and presses into the second-row captain’s seat area where my child’s rear-facing car seat is installed. This movement pushes the child’s head forward. In addition, the second-row seat controls sometimes do not respond when pressed, or the seat moves in the opposite direction from the one selected. I am concerned about my child’s safety from the seat movement and about being stranded with my three children if the vehicle fails to start again. I am reporting the conditions I observed. Hyundai has not provided me with a diagnosis explaining the no-start failure or the seat behavior.
