1997 Mitsubishi Diamante — 3.5L

The 1997 Mitsubishi Diamante sits roughly in the middle of the model's federal complaint arc, with 34 complaints logged — essentially identical to the 34 reported for 1994 and well below the late-generation surge that pushed totals to 51 in 2000, 79 in 2001, and 133 in 2002. Notably, the 1997 model year carries zero recalls and zero investigations, which is a cleaner record than several adjacent years (1992, 1993, 1998, and 1999 each show at least one recall, and 2000–2003 average two to four recalls annually). One point worth flagging is the elevated TSB count of 56, the second-highest in the entire generation behind only 2001's 66, suggesting Mitsubishi issued a meaningful volume of service guidance even though no formal recall action was taken. The complaint mix is led by Service Brakes, Hydraulic (7 of 34), with Power Train a distant second (3); two crash-related and one fire-related complaint were filed, but the underlying causes are not specified in the data. Taken together, 1997 is positioned before the clear reliability deterioration that begins around 2000, and its zero-recall status makes it a defensible choice within this generation. **Bottom line: 1997 is a comparatively strong year to target in the Diamante lineup, though buyers should specifically inspect the brake hydraulic system given its dominance in the complaint profile.**
