1989 Subaru GL-10

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 1989 GL-10.

The 1989 Subaru GL-10 rides on the "10" chassis designation and specifies 4.2 quarts of 5W-30 API oil for its engine, marking it as a distinct iteration within the model lineage. Reliability data for this model year shows minimal volatility, with only nine total owner complaints registered and a single recall campaign focused specifically on seat belts rather than powertrain or structural concerns. This low-complaint profile positions the 1989 GL-10 as a relatively unproblematic reference point in the series, offering researchers a stable baseline for examining late-eighties Subaru build quality and maintenance standards.

Reliability & federal safety record

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

Owner complaints about the 1989 Subaru GL-10 dominate in one area — the seat belts, 5 of 9 reports (56%), well ahead of the next concern. None of this vehicle's 1 recall campaigns target the seat belts, so those reports read as owner-reported wear-and-tear rather than an acknowledged defect. 2 of the reports describe a crash and 0 a fire — a small share of the total, but worth weighing against the seat belts pattern above. These are tallies of what owners actually reported to the federal government, not an editorial score — and higher-selling models naturally rack up more reports.
