What is the most reliable year for a Subaru Outback?

The most reliable years for a Subaru Outback are generally considered to be the 2009 and 2017-2019 models, as they represent the end of a generation and benefit from addressed issues while offering modern features. Other strong contenders include the 2012 and 2015 model years, with the 2005-2007 models also receiving high marks from some sources. 
Generally recommended years

• 2009: The final year of the third generation, this model is praised for its lower complaint volume and updated styling. 
• 2017-2019: The end of the fifth generation, these years are noted for improved reliability and technology like the EyeSight safety system. The 2019 model is often cited for offering a great balance of modern features and reliability at a good value. 
• 2012: A good option from the fourth generation, though some models with the CVT experienced issues. 
• 2015: Another solid choice from the fifth generation, with many owners reporting few issues. 

Considerations for specific generations

• Third Generation (2005-2009): The 2009 model year is the most recommended due to its low number of complaints and updated front-end design. 
• Fourth Generation (2010-2014): This generation introduced the CVT, which had some problems in early models, particularly the 2.5L engine. The 3.6L engine models are often considered more reliable during this period, especially those with the traditional 5EAT transmission (pre-CVT). The 2014 model year had high complaint volumes. 
• Fifth Generation (2015-2019): This generation improved reliability over the previous one. The 2015 and 2017 models are frequently recommended as strong choices. The 2019 model is a great choice, especially when looking for a blend of advanced safety and tech without the initial price tag of a brand-new vehicle. 

How to choose

• Prioritize end-of-generation models: These typically have fewer issues because problems were addressed in earlier years. 
• Be wary of early-generation models: The first model years of a new generation can sometimes have teething problems. 
• Consider the transmission: If you want to avoid potential CVT issues, look for models with traditional automatic transmissions or models that came with the non-CVT 3.6L engine (pre-2015) or manual transmission options. 

What is the transmission problem on a 2011 Subaru Outback?

Common 2011 Subaru Outback transmission problems include torque converter clutch failure, which causes the car to stall at stops, and CVT valve body issues, leading to delayed shifting or other malfunctions. These problems can be expensive to fix, with a full replacement costing thousands of dollars, as the Subaru CVTs are not easily rebuilt. Issues with the valve body are particularly common, often affecting the torque converter lockup solenoid.

Common transmission problems

• Torque converter clutch failure: This is a very common issue with the TR690 transmission used in the 2011 Outback. The torque converter clutch can fail to disengage, causing the engine to stall when stopping, similar to a manual transmission car stalling. 
• Valve body problems: The valve body contains solenoids that control fluid flow. A failure in the torque converter lockup solenoid is a common cause of stalling and other issues. Subaru does not sell these solenoids individually, so the entire valve body must be replaced, notes this YouTube video. 
• Delayed or jerky shifting: Another symptom can be delayed shifts, or the transmission jerking or lurching when changing gears. 
• Slipping: The CVT chain can slip due to wear, often caused by a lack of fluid changes or heavy use. 
• Whining or whirring noises: These sounds, especially when driving in a straight line, can indicate a problem, such as the failure of the viscous coupling in the center differential, says this Australian transmission specialist.

Symptoms to look for

• Engine stalling when you come to a stop
• Hesitation or lurching when accelerating or shifting gears
• Delayed response when shifting
• Unusual noises like whining, whirring, or grinding
• Flashing check engine light, brake light, or transmission warning lights 

What you can do

• Check the transmission fluid: Low or old fluid can contribute to problems, so check the level and condition of the fluid regularly, recommends this Facebook post. 
• Inspect for leaks: Look for reddish-brown liquid on the ground under the vehicle, which could indicate a leak. 
• Seek professional diagnosis: Due to the complexity of these CVTs, it's best to have a qualified mechanic diagnose the problem. They can help determine if it's a minor issue or if a major component, like the valve body or torque converter, needs replacement.
