Safety is enhanced with upgraded airbag systems. Late-2005 Ascender models offer the availability of rollover-sensing roof-rail curtain airbags designed to provide head protection for outboard passengers in the first and second rows. The available OnStar system, which we recommend highly, has been upgraded to better alert emergency crews and summon them to the scene in the event of an accident.
Ascender offers a slightly better warranty than the nearly identical Chevy and GMC models. Ascender comes with Isuzu's three-year/50,000-mile basic warranty, a new seven-year/75,000-mile roadside assistance program, and seven-year/75,000-mile powertrain coverage. The Chevrolet and GMC versions of the vehicle are covered by a three-year/36,000-mile warranty program. Next Page
