Do Subaru Outbacks have transmission problems?

Yes — some Subaru Outbacks have experienced transmission problems, particularly among certain CVT-equipped models from the early to mid-2010s. Overall reliability has improved in newer model years, but issues can still arise depending on maintenance and usage.

To understand the question, it helps to know that Subaru has used several different transmissions in the Outback over the years. The primary concern in recent history centers on the continuously variable transmission (CVT) that has been standard on most 2.5-liter models, while some older or higher-performance variants used traditional automatic transmissions. This article breaks down what to look for, which model years have been most affected, common symptoms, recalls, and best practices for ownership or purchase decisions.

Transmission types in Subaru Outbacks over the years

The Outback has used both conventional automatics and CVTs depending on the generation and trim. The most persistent reliability concerns have related to the CVT (often marketed as Lineartronic), which has been paired with the 2.5-liter engines in many models since the early 2010s. Some earlier or top-end configurations did use traditional automatics, but the CVT configuration has been the focal point for transmission-related warranty campaigns and owner reports.

Understanding which transmission your specific Outback has is important when evaluating potential problems, and it also helps explain why some owners report issues more than others. Below is a concise look at a few key points related to transmission types and their potential trouble spots.

Notable takeaways: CVTs have been the source of the most publicized issues in Outbacks, whereas traditional automatics—when present in certain generations—carried different failure modes. As Subaru updated CVT hardware and software over the years, later models tended to be more reliable, though no transmission system is immune to wear or harsh operating conditions.
