If a dealer dismisses a noise as "normal" but you suspect a problem, request a test drive with a master technician present and compare with a known-good identical vehicle. For HPFP issues, Hyundai has reportedly released an upgraded fuel pump design that, combined with software updates, resolves persistent abnormal noise and performance problems. Hyundai 1
