The 2008 model year was the Ascender's last, and one of Isuzu's final light vehicles in North America before the brand withdrew from that market. Only the five-passenger S remained, powered by the 4.2L inline-six with rear- or four-wheel drive. Low production makes good reference information hard to find, which is why a year-matched manual is worth having. This service and repair manual covers the 2008 Ascender with procedures, specifications, torque values, wiring diagrams, diagnostics and maintenance schedules for the Vortec six, its automatic transmission and the chassis it shares with GM's midsize SUVs.

Known issues on the 2008 Ascender. One recall is on federal record. It covers the headlamp driver module, which may overheat and fail so that the headlamps and daytime running lights do not come on. Headlamp control wiring diagrams and module replacement steps are part of the manual's lighting section.
