Subaru Outback cvt failure problems

Filed Oct 14, 2026 · Engine, Transmission · CA

I have a 2020 Subaru Outback with just over 70,000 miles on it. Well before hitting 70,000 miles, there were two occasions where a loud, unusual noise occurred while reversing out of my garage. Additionally, I occasionally hear a strange noise when shifting into Reverse from Park. I also sometimes notice a whining or humming sound when accelerating from a complete stop, such as at a traffic light. Regarding the two loud noises I experienced, I have saved an audio file recorded by another consumer who posted it online describing the exact same issue — the sound is identical to what my car produced on those two occasions. The audio file is available upon request and may assist in diagnosing the issue. Please note that the date I provided for when the noise first occurred is approximate, as I cannot recall the exact date. Since the noise occurs most frequently during reverse, I am concerned there may be an issue with the CVT transmission.

Brand new 2026 Outback experienced a "Sudden Unintended Acceleration / Brake Ineffectiveness. This occurred 3 times this week after the car had been driven over 90 miles or over 90 minutes. Engine and components were warmed up. Car was initially reported to dealer 10/6, car was examined by dealer and returned to me later that day.could not be replicated. Car sat at my home until today when it was driven over 90 minutes or 90 miles. Replicated failure by me same as earlier in the week . Car drivetrain felt surged. CVT fighting brake system when trying to turn car at street corner. Would not stop until on straight away ( seems to be triggered when turning and car was hot and when no power applied to engine. Only stops on straight away.. Could be related to cvt torque converter? Software glitch? Force of turning wheel?

Noticed minor hesitation in the reverse down our driveway Aug 2024. By Aug 2026, the transmission hesitation has turned into very noticeable shudder and slip. In reverse down the driveway, the TR580 CVT was showing premature initial failure resulting in unexpected loss of motive power control as well as acceleration hesitation in forward. This transmission defect compromised the ability to safely navigate down the driveway and through traffic, creating an risk of a rear end collision and stranding the vehicle in a hazardous roadway position. The vehicle was driven to Austin Subaru dealer early September 2026 where certified technicians inspected it. They diagnosed a catastrophic internal failure that is pending and stated the entire transmission assembly requires complete replacement. We were quoted an out of pocket retail repair cost of $9,774. Additional consideration: This defect occurred at exceptionally low mileage (<37,000) on a well maintained vehicle as it included Subaru provided services through April 2025. Only had a single oil change at a third party. Furthermore, Subaru of America Corporate Customer Advocacy was contacted regarding this exact VIN. Despite Subaru previously issuing a warranty extension program for identical transmission "judder" and slipping defects on 2019-2020 models (extending coverage to 10 years/100,000 miles), corporate formally denied coverage for my vehicle. This indicates that the dangerous premature CVT failure defect extends beyond the specific manufacturing batches Subaru has currently acknowledged, leaving drivers exposed to sudden loss of propulsion at highway speeds. I am requesting the federal safety agency investigate the 2020 Subaru Outback TR580 CVT for inherent safety defects leading to sudden loss of motive power.

The CVT transmission in my 2013 Subaru Outback failed at approximately 93,000 miles. Approximately three weeks prior to the failure, I noticed an unusual sound while driving, but no other symptoms were apparent at that time, so I continued monitoring it. On the day of the failure, the rear tires began hopping and I lost acceleration while driving. Fortunately, this occurred while I was on my driveway, so I did not need to continue driving further. I parked the vehicle there and had it towed to my mechanic, and later to Rairdon Subaru of Auburn (WA), where the failure was diagnosed by their service department. The vehicle is available for inspection there. This loss of power and erratic rear-end behavior created a safety risk, as the same failure occurring while driving on a road could have affected the vehicle's ability to accelerate and respond predictably in traffic. This is a known issue: Subaru's own Technical Service Bulletin 16-107-17R acknowledges CVT transmission problems in 2010–2015 model year Outbacks and other models, and extended the powertrain warranty coverage for this issue to 10 years or 100,000 miles. My vehicle has only about 93,000 miles, but Subaru is denying full warranty coverage because the vehicle is outside the 10-year time limit, despite being well under the mileage limit. The vehicle has not been inspected by police or insurance representatives — this was a mechanical failure, not a collision.

Needed to move quickly out of way of oncoming traffic, but delay/hesitation in CVT made it almost impossible to avoid traffic.

The CVT failed at 62 miles per hour on a busy interstate, XXX. This caused the drivetrain to lock. The car has been repaired and traded locally in [XXX]. The car was very difficult to steer with locked wheels in traffic. This was a rapid evasive manuver on a busy interstate. An undrivable vehicle on an interstate is life threatening to many. Flat bed driver told me I was lucky to steer off of lanes onto shoulder with four locked wheels. This incident put me in mild shock. The Subaru dealer had to replace the transmission. The dealer and Subaru Regional Rep. examined the CVT failure. It was outside of the 100,000-mile warranty by about 895 miles. Repair invoice attached. I did not have advanced warning of CVT failure. There were no warning lights on before the CVT failure. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

While driving the 2016 Subaru Outback, the vehicle experienced a sudden, catastrophic failure of the Continuously Variable Transmission (CVT). The transmission completely failed, resulting in an immediate and dangerous loss of propulsion while operating the vehicle. This created an immediate safety hazard for myself, my toddler and other drivers on the road, as the vehicle could no longer maintain speed or accelerate safely to clear traffic. A certified repair facility diagnosed the issue as a complete internal mechanical failure of the transmission, requiring a total replacement at an estimated cost of roughly $11,000. This generation of Subaru CVTs has a well-documented history of premature, catastrophic mechanical failure, which Subaru of America has previously acknowledged via past warranty extensions. The sudden loss of power caused by this engineering defect poses a severe and ongoing safety risk to consumers.

SUBJECT: Formal Safety Defect Complaint: 2016 Subaru Outback – Manufacturing Nondisclosure of Latent "Day 1" Design Flaw Causing Ignition Key Entrapment, Uncommanded Steering Column Lockout, and Severe Family Safety Risk I am writing to formally report a severe, unaddressed safety defect and a deceptive corporate practice by Subaru of America, Inc. affecting my 2016 Subaru Outback. This vehicle suffers from a "Day 1" latent engineering flaw that causes the physical ignition key to become permanently trapped in the ignition cylinder, triggering an uncommanded, rigid locking of the steering column assembly. Subaru has possessed documented knowledge of this failure for years, cataloging it under Technical Service Bulletin TSB 16-112-18R. Rather than fulfilling its statutory obligation to issue a comprehensive federal safety recall, Subaru deployed a voluntary, time-bound 8-year warranty extension. Subaru conveniently did not notify me of this warranty extension. By doing so, the manufacturer unconscionably ignored this defect, placing its customers at direct peril. They capitalized on asymmetric information to shift both the financial burden and the severe physical safety risks of a known factory flaw onto my family, the moment an arbitrary time threshold expired. My family and I have been at active, continuous risk in this vehicle since the day we purchased it due to an engineering error that was present when the car rolled off the assembly line. The root cause of this failure is a fundamental engineering defect within the Continuously Variable Transmission (CVT) shifter assembly, specifically, the premature degradation of the electrical contacts within the select lever park-range switch.
