Key Takeaways for your Subaru

Here are the 4 key takeaways summarizing the common problems detailed below for Subaru

Engine & Oil System

Subaru’s Boxer engines frequently face blown head gaskets, engine failure, and oil leaks, especially after 100,000 km. Symptoms include overheating, knocking, and oil consumption. Timely synthetic oil changes, coolant flushes, and gasket replacements are essential to preserve engine health and avoid catastrophic mechanical damage.

Transmission & Drivetrain

Common Subaru drivetrain problems include CVT failures, unintended acceleration, and O2 sensor malfunctions, particularly between 100,000–150,000 km. These faults lead to jerky acceleration, emissions failure, and transmission warning lights. Regular CVT fluid changes and sensor replacements help maintain performance and reduce costly repair risk.

Electrical & Lighting

Subaru models often experience electrical system issues, battery drain, and defective light switches after 60,000 km. These problems result in non-start conditions, flickering lights, and dashboard errors. Diagnosing the BCM, replacing switches, and updating software are key to maintaining reliable electrical function and safety.

Glass, Cooling & Cabin

Frequent issues like cracked windshields, coolant loss, and HVAC-related faults affect models like the Outback and Forester. These can compromise visibility, engine temperature, and interior comfort. Addressing cooling leaks early, replacing windshields, and flushing coolant regularly improves durability and cabin experience.

Top 10 Subaru Problems

A breakdown of the top 10 common repair and maintenance problems in Subaru cars.

Cracked windshields are a common problem in Subaru models like the Outback, Forester, and Ascent, often occurring within 30,000–60,000 km. The issue is linked to thin glass design, poor insulation, or stress from frame flexing. Drivers frequently report cracks forming without direct impact. Subaru has faced class-action lawsuits over windshield quality. Prompt replacement and avoiding extreme temperature shifts may reduce risk. Some models qualify for warranty repairs or glass recall coverage, depending on production year and VIN eligibility.

Top 5 Most Frequently Asked Questions About Subaru Vehicles

Answers to the most common Subaru problems, maintenance questions, and repair concerns.

The biggest issue with Subaru vehicles—especially those built before 2015—is blown head gaskets, particularly in 2.5L Boxer engines found in the Outback, Forester, and Legacy. These failures typically occur after 120,000–160,000 km and are caused by gasket material breakdown, leading to coolant leaks, engine overheating, and white exhaust smoke. Subaru has since improved gasket designs, but older models remain vulnerable. Regular coolant flushes, oil changes, and early gasket inspections are key to preventing catastrophic engine damage in high-mileage Subaru engines.
