2021 Subaru Outback problems owners report most
2021 Subaru Outback problems are documented in public: owners have filed 299 complaints with NHTSA, the earliest in 2020 and the most recent in 2026. Sorting those by the component the filer named puts the visibility/wiper clearly first, at 98 of the 299 complaints, close to a third of everything filed.
A complaint is not a repair bill and not a defect finding. It is one owner telling the regulator something went wrong. What makes the count useful is the concentration: when one component takes 33 per cent of everything filed on a car, the pattern is doing more than chance.
| Component | Complaints | Share |
|---|---|---|
| VISIBILITY/WIPER | 98 | 33% |
| ELECTRICAL SYSTEM | 76 | 25% |
| UNKNOWN OR OTHER | 66 | 22% |
| FORWARD COLLISION AVOIDANCE | 29 | 10% |
| ENGINE | 21 | 7% |
| VEHICLE SPEED CONTROL | 19 | 6% |
Against the 2020 car, this model year has drawn 67 per cent fewer complaints (299 against 904). Both years are led by the visibility/wiper, so this is a fault that carried over rather than one introduced with the 2021 car.
Of those complaints, 9 describe a crash and 2 describe a fire. Filers reported 4 injuries.
Recalls on the 2021 Subaru Outback
A recall means the manufacturer or the regulator found a safety defect, and the repair is free at a franchised dealer however old the car is. There are 4 recalls on this model year. Your own car may be covered by some, all or none of them, so check the VIN rather than the model.
Subaru of America, Inc. (Subaru) is recalling certain 2021 Outback and Impreza vehicles. The continuously variable transmission (CVT) select lever cable nut may not have been tightened properly, allowing the nut to loosen.
The risk. 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.
Subaru of America, Inc. (Subaru) is recalling certain 2020-2021 Outback and Legacy vehicles. A programming error in the Transmission Control Unit (TCU) may allow the clutch to engage before the drive chain is completely clamped.
The risk. An improperly secured drive chain may slip and break, causing a loss of drive power and increasing the risk of a crash.
The fix. Dealers will reprogram the TCU, inspect TCU data for chain slip, and visually inspect the chain guide. If evidence of chain slippage or damage is found, the transmission will be replaced. Repairs will be performed free of charge. Owner notification letters are expected to be mailed August 24, 2022. Owners may contact Subaru's customer service at 1-844-373-6614. Subaru's number for this recall is WRK-22. This recall is an expansion of previous recall number 21V-955.
Subaru of America, Inc. is recalling certain model year 2021 Crosstrek, 2022 Forester, 2021-2023 Legacy, and Outback vehicles. An insufficient weld may allow water to enter the inhibitor switch, causing it to fail.
The risk. An inoperative inhibitor switch may prevent the reverse lights from illuminating and the rearview camera image from displaying, increasing the risk of a crash.
The fix. Dealers will replace the inhibitor switch, free of charge. Owner notification letters were mailed January 8, 2024. Owners may contact Subaru customer service at 1-800-782-2783. Subaru's number for this recall is WRQ-23.
Subaru of America, Inc. (Subaru) is recalling certain 2020-2022 Outback and Legacy vehicles. A capacitor in the sensors for the Occupant Detection System (ODS) may crack and short circuit, which can prevent the front passenger air bag from deploying in a crash.
The risk. An air bag that does not deploy during a crash can increase the risk of injury.
The fix. Dealers will replace the ODS sensors on the front passenger seat, free of charge. Owner notifications were mailed February 3, 2025. Owners may contact Subaru customer service at 1-844-373-6614. Subaru's number for this recall is WRA-24.
In owners own words
These are complaints filed about the visibility/wiper, quoted as written. They are one persons account rather than a diagnosis, and they are here because a symptom described by a driver is easier to recognise than a component name.
The component that has failed twice is the windshield. They current windshield is available for inspection but not the first. In fact, I am taking it my Subaru dealer tomorrow so they can look at it. This is the second windshield in 13 months that has failed. The first one became heavily pitted across the entire windshield. This one has a crack starting from the passenger side, 2/3 of the way up and then continues 1/3 of the way towards the driver. I do not recall any impact on the windshield prior to the crack occurring. I am concerned about the frequency of this model's windshield issues an
We purchased a new 2021 Outback Subaru 2 months ago. Three days ago, on 11/12/21, a crack appeared on the windshield overnight, while the car was parked on our driveway. Nothing hit our car while we were driving and there's nothing that stands above the car that could have fallen on it while parked at our house. The crack is linear and started on the very left side right above the driver's sight. It started at about 5 inches long and the next day was already extending almost halfway through the windshield length. We are highly suspicious that the crack is a result of a defective windshield spe
The front windshield spontaneously cracked sometime overnight, while my car was parked in my garage. I noticed it when I got into my car one morning, and a roughly 6 inch horizontal crack had appeared, originating from the driver's side edge about halfway up the glass. I immediately got out and inspected the crack to find a point of impact, but it was a perfectly smooth crack line w/ zero points of impact. I drove the short distance to my destination, and an hour or two later when I got back in the car, it had continued to grow to maybe double the previous size (now 15-20" wide). The crack was
The headlights on this vehicle are obnoxiously bright! I get flashed by oncoming drivers constantly at night. I even get flashed by pickup trucks. I'm not sure if it's the main headlamps or the fog lights. It does seem like the fog lights have really poor beam control. When driving on a country road at night I can tell the fog lights are lighting up the tops of trees by toggling them on and off. I passed an oncoming car just like mine a while back and I could finally understand why I get flashed all the time. They ARE really blinding. I tried to bring it up with Subaru of America and the guy

How other model years compare
The same nameplate across the years we hold. Complaint counts fall naturally for newer cars because fewer of them have been on the road for long, so read the column as a rough signal rather than a ranking. In this set the 2019 Subaru Outback has drawn the most complaints and the 2021 Subaru Outback the fewest.
How to use this before you buy or repair
The reports do not gather around one obvious symptom, so read a handful of the complaints above and see which descriptions match what your car is doing.
Buying a used 2021 Outback
Bring the complaint list to the inspection and ask the mechanic to check the components named most, rather than running a general once over.
If you already own one
Check your VIN for open recalls first. A recall repair costs nothing whatever the age or mileage of the car.
- Check the VIN for open recalls, not the model year.
- Ask the inspecting mechanic about the components named above.
- Get the part number before comparing retailer prices.
- Keep parts and labour as separate lines in any quote.
Where the 2021 Subaru Outback problem data comes from
Every figure on this page is counted from complaints and recalls published by the National Highway Traffic Safety Administration, read November 1, 2026. Complaints are filed by owners and are not verified by the agency before publication. We count each complaint once per component it names, so a complaint naming two components appears in both rows.
