        How this compares

        2020 Subaru Legacy121
        Median 2020 model here (75 vehicles)219
        Median 2020 sedan here (14)201

        121 complaints is 1.8 times fewer than the median 2020 model on this site and 1.7 times fewer than the median 2020 sedan. Among the 6 Legacy model years here it ranks 4th for complaints. Counts follow sales volume as much as reliability, so a truck that sells 700,000 a year draws more reports than a sedan that sells 200,000.

        Service bulletins for the 2020 Subaru Legacy

        Subaru filed 587 bulletins and other notices with NHTSA that list the 2020 Subaru Legacy. 17 of them deal with a problem owners have reported on this car. Newest first.

        Federal rules make a manufacturer send NHTSA a copy of any notice about a defect that goes to more than one dealer or owner. Most of these are service bulletins, the repair instructions manufacturers send to dealers. NHTSA generally leaves safety recall bulletins out of this file, and recalls are listed separately.
