Reliability & federal safety record

Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.

The first-generation Subaru Forester (1998–2002) shows a volatile but generally elevated complaint pattern, with the 2001 model year representing a notable spike: 146 complaints versus just 79 in 2000 and 93 in 2002, making it the highest-complaint year of this generation. Notably, Subaru responded with a sharp increase in technical service bulletins—111 for 2001 versus 74 in 2000 and 128 in 2002—suggesting the manufacturer was actively disseminating repair guidance to dealers, though the data does not specify root causes. The 2001 carries zero recalls and zero federal investigations, matching 2000, which is favorable relative to 1999 (one recall, one investigation) and 2002 (one recall). The top complaint concentrations—Vehicle Speed Control (23), Power Train (21), Suspension (17), and Engine & Engine Cooling (14)—along with 32 crash-associated complaints, indicate real-world operational concerns that buyers should weigh, though the absence of fire complaints is a positive signal. Within the generation's arc, 2001 sits at a complaint peak sandwiched between quieter years, implying that whatever drove the surge was addressed by 2002 rather than escalating further. Given the elevated complaint volume, the high crash-complaint count, and the fact that the neighboring 2000 and 2002 model years show meaningfully fewer complaints with similar or better recall profiles, the 2001 Forester is not the strongest pick in this generation—a 2000 or 2002 model would be a more defensible choice for a used buyer seeking to minimize known-issue exposure.
