2017 Subaru Outback Common Issues by Mileage

The 2017 Subaru Outback, part of the fifth generation (2015-2019), is a popular choice for its blend of SUV utility and wagon efficiency. Known for its standard Symmetrical All-Wheel Drive and impressive ground clearance, it’s a favorite for outdoor enthusiasts. While generally reliable, like any vehicle, the 2017 Outback has a few common issues owners report as it ages. Understanding these potential problems, organized by mileage, along with their estimated repair costs, can help you budget for maintenance and keep your Outback running smoothly for years to come.

In its early life, the 2017 Outback is largely robust. Most issues encountered are minor or relate to routine maintenance and known characteristics. * **Windshield Cracking/Chipping (All Mileages):** Many owners report the windshields on this generation of Outback are prone to cracking or chipping from minor impacts. This isn't a mechanical issue but a common complaint. * **Cost:** $400 - $800 for a standard replacement. If equipped with EyeSight, calibration adds complexity and cost: $800 - $1,500+. * **Battery Drain/Premature Failure (Approx. 30,000-50,000 Miles):** Some owners experience a battery draining quickly or failing earlier than expected, often linked to the infotainment system or parasitic draws. * **Cost:** $150 - $300 for a new battery and installation. * **Infotainment System Glitches (All Mileages):** Occasional freezing, slow responses, or connectivity issues with the Starlink infotainment system are reported. While frustrating, these are often resolved with software updates or hard resets. * **Cost:** Usually free (software update) or minor diagnostic fees ($100-$200) if deeper electrical investigation is needed.

As your Outback approaches and passes the 60,000-mile mark, expect to address standard wear and tear components. Proactive maintenance, especially for the CVT, is crucial. * **Wheel Bearings (Approx. 60,000-90,000 Miles):** Due to the AWD system and general driving conditions, front and rear wheel bearings can begin to fail, presenting as a hum or growl that intensifies with speed. This is a common wear item. * **Cost:** $300 - $600 per wheel, including parts and labor. * **CVT Fluid Service (Around 60,000 Miles):** While Subaru often states the CVT fluid is 'lifetime,' many owners and technicians strongly recommend a fluid drain and fill around 60,000 miles to prolong transmission life. * **Cost:** $200 - $400 for a drain and fill. * **Brake Components (Routinely, e.g., 60,000 Miles):** Pads and rotors are typical wear items. Expect to replace them based on driving habits. * **Cost:** $300 - $700 per axle for pads and rotors.

Beyond 90,000 miles, the Outback may start to show signs of more significant component fatigue. Keeping up with fluid changes becomes even more critical. * **Lower Control Arm Bushings (Approx. 90,000-120,000 Miles):** The rubber bushings in the front lower control arms can wear out, leading to clunking noises over bumps, uneven tire wear, or loose steering. * **Cost:** $400 - $800 per axle, depending on whether just bushings or entire control arms are replaced. * **Spark Plugs (Around 60,000-100,000 Miles):** Standard maintenance dictates spark plug replacement around this interval for optimal engine performance and fuel economy. * **Cost:** $250 - $500, due to the Boxer engine's design requiring more labor. * **CVT Transmission Concerns (Potentially 90,000+ Miles):** While many CVTs perform flawlessly, some owners report issues like shuddering, loss of power, or unusual noises at higher mileages. Early symptoms may indicate valve body or solenoid issues. * **Cost:** Valve body replacement can range from $1,000 - $3,000. A full CVT replacement is a major expense: $5,000 - $9,000+.

Outbacks can easily exceed 150,000 miles with diligent care, but prepare for more extensive maintenance and potential major component replacements. * **Suspension Components (Approx. 120,000+ Miles):** Struts, shocks, and associated bushings will likely be worn, affecting ride quality and handling. * **Cost:** $1,000 - $2,000+ for all four struts/shocks and associated labor. * **Engine Gasket Leaks (Approx. 120,000+ Miles):** While the 2017 Outback's FB engine is less prone to head gasket issues than older Subarus, valve cover gaskets or timing cover seals can develop leaks over time. * **Cost:** $500 - $1,500+, depending on the specific leak and labor required for access. * **Continued CVT Vigilance:** At these mileages, any prior minor CVT symptoms could escalate. Regular fluid changes become even more critical, and any new symptoms should be investigated immediately. * **Cost:** As above, major CVT repairs or replacement remain the highest potential expense.
