2021 Genesis G80 Service and Repair Manual

This factory service and repair manual for the 2021 Genesis G80 treats two turbocharged gasoline engines — a 2.5L DOHC inline-four and a 3.5L DOHC V6 — in one four-door sedan sold as Base, Advanced and Prestige. Both are boosted, and both are direct concerns of the fuel and induction sections, where line routing, sealing and pressure specifications are given in detail. Elsewhere the arrangement is conventional: system-by-system procedures, torque values, wiring diagrams and diagnostics for the chassis, brakes, restraints and body of a single shell.

Known issues on the 2021 G80. Four recalls sit on the federal record. Three concern fuel: a tube between the high-pressure pump and the fuel rail that may not seal, a leak at the pipe-to-rail connection, and a pump that can fail outright and leave the car without drive power. The fourth is a restraint fault, where a front seat belt pretensioner can rupture as it fires and throw metal fragments into the cabin. Owners have filed 9 complaints, led by tires at 3 with the electrical system and service brakes at 2 apiece — all areas specified and tested here.
