Isuzu Ascender
Parts fit 2003 to 2008. Owner reports cover 1996 to 2025, mapped to 1 NHTSA name, so vehicles of very different ages are counted together.
24 of 213 parts name an engine. The other 119 fit any, so choosing one here only narrows those 24.
What owners report
6 of 12 components, the largest by share, together 65.2% of all mentions. 99 reports filed with NHTSA from 1996 to 2025, read through 2 name and year queries against 1 source name. A report can name more than one component, so these 99 reports carry 152 mentions, 1.54 for each report, and every share below is of those 152. 1 more mention was filed as unknown or other and is excluded from both the rows and the total.
What we can sell for it
