2021 Subaru Outback recalls & complaints
Source: NHTSA, updated daily. Last checked 2026-10-18. Recalls apply to specific VINs — run your VIN to confirm.
4 safety recalls, most serious first
1. Transmission / drivetrain
What's wrong, in plain English: The parts that send engine power to the wheels. Failure can mean a sudden loss of power or the car rolling away. The continuously variable transmission (CVT) select lever cable nut may not have been tightened properly, allowing the nut to loosen.
What could happen: A loose nut can lead to a lost of retention in the CVT select lever cable and the gear selector not functioning properly, increasing risk of crash.
The fix: Subaru will notify owners, and dealers will inspect, and, if necessary, tighten the nut, free of charge. The recall began February 12, 2021. Owners may contact Subaru customer service at 1-844-373-6614. Subaru's number for this recall is WRA-21.
What to do
- Check whether your car is affected: enter your 17-digit VIN at nhtsa.gov/recalls. A recall covers specific VINs, not every 2021 OUTBACK.
- Book a repair at any authorized Subaru dealer. Quote NHTSA campaign 21V024000 (manufacturer code WRA-21).
- The repair is free. By US law, safety recall repairs cost the owner nothing, no matter the car's age or mileage.
- Manufacturer hotline: 1-844-373-6614.
- Buying this car used? Ask the seller for proof the recall was completed, or run the VIN yourself before paying.
