Which year of Subaru Outback is the most reliable?

The latest model years—2020 through 2024—are generally the most reliable. Independent reliability ratings tend to favor the sixth generation, with fewer major recalls and refined drivetrains compared with earlier Outbacks. That said, reliability still depends on maintenance history and how a vehicle was cared for by its previous owners.

To understand where reliability stands, this article reviews data from Consumer Reports, J.D. Power, and recall histories, and explains how outcomes vary by generation, engine type, and model-year refinements. It also offers guidance for buyers evaluating used Outbacks and what to look for when assessing long-term durability.

Reliability by Generation

Overview of how reliability has evolved across the generations and what that means for buyers today.

• Sixth generation (2020–present): Broadly the most reliable in the Outback line, with refined CVT operation and fewer large recalls; owners report strong long-term durability when serviced regularly.


• Fifth generation (2015–2020): Generally dependable, with solid drivetrain performance and good overall durability; some model-year groups experienced CVT-related quirks or recall campaigns, but reliability remains strong overall.


• Earlier generations (1990s–2014): Reliable in many ways, but older powertrains and age-related maintenance drive higher ownership costs; traditional Weak Points like head gasket tendencies in older EJ engines have influenced reliability perceptions.

Bottom line: Newer Outbacks deliver the strongest reliability, while older models require careful maintenance and a thorough pre-purchase check.

Notable Issues and How They Impact Reliability

Key issues that have shaped reliability perceptions across model years include the following.

• Head gasket and engine sealing concerns in the oldest Outbacks; these problems are far less common on the modern engines used in the sixth generation.


• CVT wear and software/driveability concerns in mid-generation models; Subaru issued recalls and service campaigns to address transmission issues.


• Occasional electrical glitches and infotainment glitches reported by some owners; these are typically resolved with software updates or component replacements under warranty or recall programs.

These patterns underscore the importance of maintenance history and a thorough pre-purchase inspection when evaluating reliability.

Buying Tips for a Reliable Outback

When shopping for a used Outback, the following steps help identify a more reliable example.

• Check full maintenance records, including regular oil changes, cooling-system service, timing-related work where applicable, and any recall repairs.


• Verify that recall items have been addressed by an authorized dealer; request proof or VIN-level recall history.


• Prioritize models with low to moderate miles and a documented service history, ideally with multiple years of Subaru service records.


• Have a pre-purchase inspection performed by a qualified mechanic, focusing on the engine, CVT condition, cooling system, head gaskets, and suspension/steering components.


• Test drive to assess CVT smoothness, transmission response, and idle behavior; listen for abnormal noises during acceleration and deceleration.

Concluding: A thorough pre-purchase inspection and a clean service/recall history are the best indicators of future reliability.

Bottom Line: Which Year to Choose?

For most buyers, the safest bet is a 2020–2024 Outback with a clean maintenance and recall history. If you are buying used from older years, target late-2010s models (2018–2019 or 2016–2017 depending on availability and history) that have full service records and an inspection from a trusted shop. Avoid unloved older examples with patchy maintenance histories or unresolved recalls.

Summary

Reliability in the Subaru Outback has generally improved with the sixth generation, making 2020–2024 models the best overall choice for long-term durability. However, the true measure of reliability is maintenance history; regardless of year, a well-serviced Outback with a clean recall record is likely to be the most dependable. Buyers should prioritize recent model years and insist on thorough maintenance documentation and a professional pre-purchase inspection to maximize confidence in reliability.

What is the least reliable year of the Subaru Outback?

The worst years for Subaru Outback include 2010–2014 and 2017–2020 due to major issues like airbag defects, engine failure, CVT transmission problems, electrical faults, and frequent windshield cracks. These model years show high NHTSA complaint rates and known recalls.

Newer models

• 2022-2025: Excellent safety ratings and reliability. The 2022 offers modern tech and a great driving experience without the highest price tag.
• 2017-2019: Strong contenders from the previous generation, with the 2017 featuring an upgraded infotainment system. 

Older models

• 2009: The final year of its generation, it is known for high owner satisfaction and fewer complaints compared to other model years. 
• 2005: A good budget option with solid ground clearance and standard all-wheel drive. A 250-horsepower turbocharged engine was also available. 

What to consider

• Safety: Every Subaru Outback from 2010 onward has earned an IIHS Top Safety Pick or Top Safety Pick+ award. 
• Resale value: The Outback holds its value well, making it a smart investment. 
• Reliability: While most model years are reliable, some specific years like 2010-2014 had engine and transmission issues and should be approached with caution, according to this AGT Europe Automotive Import SA article. 

What is the most reliable year of the Subaru Outback?

The most reliable years for the Subaru Outback are generally considered to be the 2017-2018 models and the 2008-2009 models. Newer models like the 2022 have also received good ratings, while the 2010-2014 and 2019-2020 model years have been noted for having more common issues, particularly with the CVT transmission in 2.5L models. 
Reliable models

• 2017–2018: Part of the fifth generation, these models are praised for improved reliability and the updated infotainment system with EyeSight safety features. 
• 2008–2009: The final years of the third generation, these models received above-average scores from J.D. Power for initial quality and reliability. 
• 2022: The 2022 model has received praise for its safety and is considered a reliable option from the current generation. 

Models to approach with caution

• 2010–2014: These years saw the introduction of the CVT, and some 2.5L models experienced transmission issues. The 3.6L models with the 5-speed automatic are often considered more reliable during this period. 
• 2019–2020: Some owners and mechanics report a dip in reliability for these model years compared to earlier or later versions. 

Tips for buying a used Subaru Outback

• Avoid the first year of a new generation: The first year of a new design or significant technology update often has more issues that get ironed out in later model years. 
• Inspect for common problems: Depending on the generation, be on the lookout for issues like head gaskets on 2.5L engines, oil consumption, or rust on the subframe, especially in older models. 
• Prioritize maintenance records: A well-maintained Outback of any year will likely be more reliable than one that has been neglected.
