2027 Hyundai Palisade Hybrid

My new 2027 Hyundai Palisade Hybrid experienced a hybrid-system/power-supply malfunction with fewer than 500 miles. The Hyundai dealer diagnosed DTC P0C381C on August 28, 2026 and has retained the vehicle since that date. Hyundai Motor America has issued Limited Coverage Campaign LA39, titled “HPCU Warning Light On – HPCU Software Update – DTC P0C381C.” However, Hyundai's communication states that LA39 is currently for impacted dealer-stock vehicles only. It states that already-retail vehicles must wait for a separate campaign that is “pending review/approval” and that those customers should be placed in alternative transportation. I am concerned that Hyundai is presently correcting affected unsold inventory while vehicles already sold to consumers that actually experience P0C381C remain unrepaired pending approval of a separate retail campaign.

"Stop vehicle and check power supply" warning lights accompanied and panic alarm goes off on new 2027 palisade hybrid calligraphy with 72 miles. The passenger rear brake grabs much more than the others which you can barely feel. Johnson Hyundia of Apex,NC, where we purchased the vehicle tell us not to bother bringing it to them because unless it has a fault code or constant message, they can't do anything. Hyundia corporate gave me a case number but acted like they never heard of it happening to anyone else. Reddit posts have at least 20 other cases of this same thing happening to new hybrid vehicles.
