1999 Subaru Impreza — 2.5L

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 1999 Impreza 2.5L. Covers both the standard and High Output 2.5L.

Engine 2.5LTransmission Automatic 4-spd

The 1999 Subaru Impreza pairs the 2.5L engine with a four-speed automatic transmission and earns an EPA rating of 20 city, 26 highway, and 22 combined mpg, with service calling for 4.2 quarts of 5W-30 API oil. Owner-reported data for this model year shows 22 complaints led by the suspension, alongside three recalls, a figure that sits well below the 300-complaint peak the Impreza would reach in 2002. Viewed across the model's 1990–2026 reporting span, the 1999 belongs to the early, lower-complaint end of a curve that later climbed to its high in 2002 and ultimately bottomed out at a single complaint in 2026. For a researcher, the implication is that this particular year stands out on the quiet side, with suspension as the defining issue and three recalls as the headline service record.

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 model sits near the low‑point of the generation’s complaint curve, with only 22 complaints—well below the mid‑1990s peaks of 64 (1995) and the 1998 rise to 46, and far under the dramatic surge after 2002 (e.g., 300 complaints in 2002). Recall activity for 1999 (3 recalls) is comparable to the surrounding years (3 in 1998, 3 in 2000) and does not reflect the heightened recall counts seen in the 2008‑2011 window (15 recalls per year). Technical Service Bulletins (TSBs) peaked in 2000 (71) and then exploded after 2008 (over 200), whereas 1999’s 36 TSBs are modest relative to later years but higher than the early‑1990s baseline. The top complaint areas—suspension, vehicle‑speed control, power‑train, and airbags—are limited in number and severity, with only two crash‑related complaints and no fire complaints reported. Overall, 1999 falls in a comparatively quiet segment of the model’s history, suggesting it is a relatively safe year to consider for purchase.
