1999 Subaru Forester

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 1999 Forester.

Body PASSENGER CARTransmission Automatic 4-spd

The 1999 Subaru Forester is classified as a passenger car and is equipped with an automatic four‑speed transmission that runs on 4.2 qt of 5W‑30 API oil, delivering EPA fuel‑economy ratings of 18 mpg city, 24 mpg highway and 20 mpg combined. Its power‑train was the most frequently cited area in owner feedback, accounting for the 141 total complaints recorded for the model year, yet the vehicle required only a single recall. When viewed against the broader 1998‑2026 complaint timeline—peaking at 831 complaints in 2019 and dropping to a low of 12 in 2026—the 1999 Forester sits toward the lower‑end of reported issues, suggesting a relatively solid reliability standing for its early generation.

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 1999 Forester sits within a first-generation arc (1998–2002) that shows a notable spike in owner complaints for this model year. At 141 complaints, it exceeds both the preceding 1998 (112) and the following 2000 (79), and it is the only year in this generation to trigger a federal investigation. While recalls remain steady at one—matching 1998 and 2002—the combination of elevated complaints, an open investigation, and top problem areas concentrated in the power train (28), engine (23), and suspension (21) suggests a year with more unresolved quality concerns than its immediate neighbors. The data does not specify root causes, but the pattern implies that 1999 may carry a higher risk of encountering these reported issues. For a buyer prioritizing reliability within this generation, the 2000 model year, with zero recalls, no investigations, and significantly fewer complaints, presents a more favorable profile.
