2020 Subaru Outback transmission problems

Filed Nov 3, 2026 · Transmission · TX

Hendrick Honda Cars of McKinney sold me a 2020 Subaru Outback with severely mismatched tires, completely failing to identify the issue despite passing the vehicle through three separate pre-sale and/or safety inspections. Subaru strictly requires identical tire tread depths across all four wheels on its symmetrical All-Wheel Drive (AWD) system to maintain stable power distribution and vehicle control. Selling and operating an AWD vehicle with a critical tread depth variance (5/32" vs 10/32") forces the tires to rotate at different speeds, putting severe, un-designed friction and heat stress on the center differential. This introduces an immediate, permanent risk of unexpected drivetrain binding, catastrophic mechanical failure, or sudden loss of vehicle control at highway speeds. To further mask this hazard, the dealership installed subpar new tires and actively deleted the vehicle's wheel alignment data from Internal Repair Invoice #369267 to hide the defect. When I subsequently forced the facility to run a proper alignment check, the data confirmed the vehicle was dangerously out of alignment. I complained about slipping and the smell of rubber numerous times to be told my tires and vehicle were safe. By intentionally deleting tracking data and pushing a dangerously misaligned, mismatched AWD vehicle through three consecutive inspections, the facility actively covered up a severe mechanical safety risk, exposing the driver and public to potential drivetrain failure and loss of control. They have admitted to this in writing also..

I was driving my 2020 Outback and all of a sudden, I heard a thump, like something dropped and it shut down. I was on a major highway and it totally scared me. Thankfully, the car right behind me swerved, preventing a collision. I have around 160,000 miles on it. It was then towed. Adventure Subaru in Fayetteville, AR looked it over. The transmission is bad, and it needs to be replaced. I am not sure if there have been any recalls on my vehicle that pertain to the Transmission. I have also contacted Subaru of America and waiting to hear back. No, there were no warning signs.

1. What component or system failed or malfunctioned, and is it available for inspection upon request? The rear differential assembly completely failed, disabling the vehicle's all-wheel-drive capability. The component was replaced by Shingle Springs Subaru, so the original failed part is no longer available for physical inspection, but all diagnostic and repair receipts are available upon request. 2. How was your safety or the safety of others put at risk? Around 73,000 miles, during a major winter snowstorm, I was starting to drive up a hill when the vehicle lost traction and the car would not move forward and began sliding. This sudden loss of control in severe weather put me, my [XXX] child, and all surrounding drivers at immediate risk of a catastrophic crash on a hazardous road with no warnings. 3. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes. The complete failure of the rear differential was officially diagnosed, confirmed, and replaced by the service department at Shingle Springs Subaru. 4. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? The failure was inspected and documented by Shingle Springs Subaru. Furthermore, corporate Subaru (the manufacturer) reviewed the dealership's case files and confirmed the situation enough to issue a $1,000 goodwill assistance gesture toward the repair. 5. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? There were no warning lamps, dashboard messages, or obvious symptoms prior to the incident. The vehicle had its major 60,000-mile factory service completed around 61,000 miles, and no issues were flagged by the mechanics. The catastrophic failure of the all-wheel-drive system only became apparent when the vehicle was subjected to the slick conditions of the winter storm.

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.

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.

From when we purchased this car new until the day we traded it. There were many times on the freeway at 60-65 MPH that you would need to move over a couple of lanes and went to wide open throttle and the car would simply do nothing for 1 to 2 seconds. I recently learned that in 22' Subaru had a software update to rectify this issue. Meaning there are plenty of Subaru owners who are driving around in cars that put their safety at risk. When you step on the gas you need and expect the car to accelerate .

My transmission has started to fail. The check engine light came on the error code read p0867, transmission fluid pressure. Other lights came on as well because it tripped the rest of the sensors because of the CVT failure. This seems to be a common problem in Subarus

I was reversing out of a residential driveway onto a county highway when the I had a complete loss of movement. Shortly after the total loss of power, the CEL illuminated. If I had been on the highway, the driveway is near a blind curve, I would've been sitting in the road with no way to move putting me in a dangerous situation. The transmission failed at right at the end of the driveway so I was able to put it in neutral and move the vehicle by hand. There were no symptoms or warning lights prior to the failure. I had it towed to the nearest dealership where they diagnosed a complete transmission failure and recommend a complete transmission replacement.

I'm writing to request assistance with my recall. This recall was first reported to the local dealership over one year ago. They have had me take the car back 4 times for inspection. Since that time as the problem has proceeded to get worse, which will now cost even more to repair, and increase the likelihood of the transmission damaging other parts of the drivetrain. Now I just received notification that they will not perform the recall as my vehicle doesn’t qualify. It has the problem of transmission slipping which is what the recall is for. I saw the pictures they took that looked exactly like the problem specified. I do not have $7000 dollars plus to fix the transmission. I can’t sell the car because the VIN will show the recall (which I’m sure they will try to just remove). All they have done is waste my time for the last year to do what? Gather enough evidence to try and get out of the recall?

On December 28, 2025, my 2020 Subaru Outback lost the ability to engage any gear (Drive, Reverse, or otherwise) while maneuvering at low speed to make a U-turn. The vehicle became inoperable immediately and was towed to the dealer. The dealer confirmed via text and written estimate that there was no external damage, the failure was internal to the CVT transmission, and the transmission requires replacement. This vehicle has approximately 90,023 miles. The failure occurred under the mileage and age range covered by Subaru CVT warranty extensions for similar vehicles. Subaru of America reviewed the case and denied coverage, citing VIN exclusion and prior service gaps that predated my ownership. The vehicle is currently inoperable and presents a safety risk due to loss of propulsion. I am reporting this to the federal safety agency because it may indicate a systemic defect in CVT transmissions on this model year Outback.
