    On the 2023-2026 Genesis G90 3.5L Twin-Turbo V6 (Smartstream), on G90s painted in Savile Silver, the aluminum-heavy paint formulation at the corners of the front bumper cover reflects the corner-radar signal back into the sensor. Highway Drive Assist (HDA) interprets the reflection as a vehicle cutting into the lane and applies sudden, unintended braking — reported at low speed (below ~12 mph) and when Lane Change Assist is active. Only Savile Silver cars are affected. Covered by NHTSA Recall 25V833 (483 U.S. vehicles).

    Common Symptoms

    • Sudden unintended braking
    • Phantom emergency braking with no obstacle
    • False forward-collision alerts
    • Braking when Lane Change Assist engaged

    How to Fix

    Under recall 25V833 a certified Genesis technician seals the front bumper beam so the radar signal is not transmitted through the body panel to strike the paint. Free of charge. As an interim measure owners can disable HDA/forward-collision-assist braking if experiencing phantom braking, and confirm the bumper-beam remedy has been applied.

    On the 2023-2026 Genesis G90, on second-generation G90s, the driver and front passenger seat belts attach to the seat frame through a snap-on anchor that can break, so the anchor does not securely fasten the belt to the structure. If the anchor separates in a crash the belt cannot restrain the occupant, which defeats the restraint entirely at the moment it matters. This is a different defect from the earlier pretensioner over-pressurization problem - nothing ruptures or fires here; the load path simply comes apart at the seat-frame end. Hyundai and Genesis covered roughly 294,000 vehicles across several nameplates in this action, with the 2023-2026 G90 among them, so late-model and even current cars are in scope and many are still in owners' hands unremedied.

    Common Symptoms

    • Seat belt lower anchor feels loose or moves at the seat frame
    • Belt webbing sits abnormally or the buckle stalk shifts
    • Rattle or clunk from the base of the seat belt
    • No warning light - the defect is usually silent

    How to Fix

    Free recall remedy under NHTSA campaign 26V218000. Genesis retailers inspect the driver and front passenger seat belt anchors and reinforce or replace them as necessary at no charge; owner notification letters were mailed beginning May 29, 2026 and affected VINs became searchable on nhtsa.gov in April 2026. Enter the VIN at nhtsa.gov/recalls to confirm status - a used-car purchase completed before the notification date will not have been contacted. There is no safe interim workaround: an anchor that has already snapped cannot be detected by the occupant, so schedule the inspection rather than waiting for a symptom.

    On the 2023-2025 Genesis G90, a software bug supplied by LG Electronics in the digital instrument cluster causes the entire IP display to go blank at startup on 2023-2025 G90s built Apr 21, 2022 - Apr 7, 2025. With no speedometer, warnings, or system status visible, the condition violates FMVSS 101. Genesis recall 027G / NHTSA campaign covers 2,345 G90 units (part of a 4,754-vehicle total with GV60).

    Common Symptoms

    • blank instrument cluster at startup
    • no speedometer
    • missing warning lights
    • intermittent display dropout

    How to Fix

    Recall 027G: free OTA software update pushed to the cluster, or a dealer flash if OTA fails. If your cluster is blank, do not drive — pull over, key-cycle, and contact Genesis at 844-340-9741 (reference recall 027G). Owner notification letters were mailed no later than September 15, 2025.

    On the 2023-2025 Genesis G90 3.5L twin-turbo GDI V6 (Lambda III), on the second-generation 3.5L twin-turbo G90, the retention fasteners on the fuel crossover pipe at the fuel-rail connections were tightened during assembly with an insufficient concentration of thread/torque stabilizer (thread retainer). Over time the fasteners can gradually loosen, allowing gasoline to seep from the crossover pipe joints. Fuel leaking near hot engine components creates an engine-fire hazard. This is a manufacturing/assembly-torque defect covered by NHTSA recall 26V229 (Genesis campaign 033G). It affects 4,231 G90 units within a larger ~94,760-vehicle Genesis action (G80/GV80/GV70 also covered), part of a combined ~235,000-unit Kia-Genesis fuel-leak action. It is a fuel-delivery-rail failure distinct from the low-pressure fuel-pump impeller recall and the turbo oil-feed-pipe fire recall.

    Common Symptoms

    • Fuel odor around the engine bay or under the hood
    • Fuel stains/wet residue near the fuel rail
    • Risk of engine-compartment fire

    How to Fix

    Under recall, dealers inspect the fuel crossover pipe and its fasteners, re-tighten them to spec with the correct torque stabilizer, and replace the fuel pipe if a leak or damage is found - free of charge regardless of warranty status, with reimbursement for prior out-of-pocket repairs. NHTSA advises parking outside and away from structures until the repair is done. VINs became searchable on NHTSA.gov April 11, 2026 and owner letters were mailed June 8, 2026.

    On the 2019-2024 Genesis G90, on rear-seat-package G90s - the Ultimate and Prestige rear entertainment/executive rear seat configurations, and the second-generation 2023-plus cars - the rear-console touchscreen and the rear seat adjustment controls stop responding together. Because the rear display, the rear climate and audio controls and the rear seat motors share the console harness and control module in the center tunnel, one failure takes all of them out at once, which is the diagnostic tell that separates this from a front-infotainment software freeze. A 2023 owner reported the rear LED screen failing and the repair taking three weeks because the technicians had to remove both rear seats, the tunnel and the rear console to reach the harness and module. It is not a safety defect, but it disables the feature set that most justifies the trim's price.

    Common Symptoms

    • Rear console touchscreen black or unresponsive
    • Rear seat power adjustment does not work
    • Rear climate and audio controls dead at the same time
    • Rear screens work intermittently after a battery disconnect

    How to Fix

    Confirm the rear display is enabled, perform the documented head-unit reset and test the correct fuses. If the screen and seat controls remain dead together, diagnose the console harness and rear control module; teardown, programming and part identity are VIN-dependent.

    Typical repair cost:$0 - $2,500
