1991 Subaru Loyale

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 1991 Loyale.

Transmission Automatic 3-spd

The 1991 Subaru Loyale shipped with a 3-speed automatic transmission and EPA fuel-economy ratings of 21/24/22 mpg, requiring 4.2 quarts of 5W-30 API oil for routine service. Reliability records from the 1990–1994 production span show this model year generated only 14 owner complaints—concentrated in the power train—and two recalls, a significantly lower volume than the 47 complaints tallied for 1992. Positioned early in the model run with markedly fewer reported issues than the peak-trouble 1992 variant yet substantially more than the final 1994 edition’s single complaint, the 1991 Loyale represents a midpoint in the line’s quality trajectory before its late-run refinement.

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 1991 Subaru Loyale occupies a relatively calm position within this generation's federal record, with complaint volume (14) holding nearly flat against 1990's 15, while recalls dropped from four to two and investigations from three to two—suggesting some of the prior year's regulatory attention was beginning to resolve. The most frequently cited complaint areas for 1991 center on the power train (four complaints), followed by latches/locks/linkages and engine cooling (two each), with one crash complaint and zero fire complaints reported. Notably, 1992 saw a dramatic spike to 47 complaints alongside a collapse in recalls and investigations to one and zero respectively, indicating that problems likely materialized after the 1991 model year rather than before it. The 1993 and 1994 model years then taper off sharply, though that decline may reflect lower production volumes or aging-out of the model rather than improved quality. TSBs held constant at 11 across all five years, indicating manufacturer technical guidance remained consistent throughout the generation. **On balance, 1991 represents a reasonable year to buy within this generation**: it benefits from the post-1990 reduction in recalls and investigations while avoiding the complaint surge that characterizes 1992, making it one of the more stable entries in the Loyale's federal record.
