2026 INFINITI QX80 Service and Repair Manual

In its second year, the redesigned QX80 swaps the Sensory for a new Sport trim, sitting between the Luxe and Autograph with darkened exterior trim, unique 22-inch wheels, semi-aniline leather and massaging seats. All 2026 trims, Pure, Luxe, Sport and Autograph, keep the 450 hp twin-turbocharged 3.5L V6 and nine-speed automatic. Trim-specific wheels, seats and electronics make year-exact data valuable, and this service and repair manual is matched to the 2026 QX80, with procedures, specifications, torque values, wiring diagrams, diagnostics and maintenance schedules.

Known issues on the 2026 QX80. Two recalls are on federal record. An infotainment software error at startup may stop the rearview camera image from displaying in reverse, which is fixed with a software update. On vehicles with 22-inch wheels, the axle weight rating on the certification label is incorrect, so new labels are installed. No owner complaints have been filed. This service and repair manual covers infotainment and camera wiring diagrams, module diagnostics and tire and wheel specifications.
