Warning problems of the 2026 Hyundai Palisade

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.

While driving, the vehicle displays a warning of "eyes on road, hands on wheel". It has happened 6x since vehicle purchase, most recent on 10 Jan 26. The most recent occurrence was 10 Jan 26. Hyundai has issued a bulletin that this could occur when wearing sunglasses. The most recent time it was raining, no sun, no sunglasses and hands were on wheel at 10/2. Warning message displayed for several seconds (eyes on road/hands on wheel) and then went into stop mode on the highway. Tapping the brakes broke the lock and are continued without stopping. Been to dealership 3x. Hyundai says it can be caused due to sunglasses. Most recent time, no sunglasses.
