NHTSA complaint #11767432

Owner complaint summary

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 NHTSA investigate the 2020 Subaru Outback TR580 CVT for inherent safety defects leading to sudden loss of motive power.
