The Outback is Subaru's rugged estate-based crossover, sitting between traditional estate cars and full-size SUVs. It has a fiercely loyal following among rural buyers, dog owners, and outdoor enthusiasts who need genuine all-weather capability without a Land Rover price tag. In the UK it remains a niche but well-regarded choice, known for go-anywhere symmetrical AWD and strong residual values.

We track 5 known issues across the Subaru Outback range, including 1 rated as safety-critical. Knowing which variants and configurations to approach with caution can save you from expensive surprises after purchase.

5 Things to Know Before You Buy
1
Subframe and suspension mounting point corrosion
Critical £800–£2,000 BL, BR, BS

The rear subframe and suspension mounting points are prone to corrosion on Outback models from 2003 onwards. MOT data shows failures at 897.1 times the fleet average, with the 3.0-litre model particularly affected between 60-80k miles. The corrosion affects the load-bearing structure within the prescribed MOT inspection area around suspension mounting points. This is a structural safety issue that can lead to suspension component detachment while driving.

If the subframe or mounting points fail structurally, suspension components can detach from the vehicle while driving, causing immediate loss of control. Welded repairs to load-bearing areas must meet strict MOT standards and typically cost £800-2000 depending on the extent of corrosion. The vehicle is not safe to drive with significant structural corrosion.

What to check

Inspect the wheel arches, sills, jacking points and door bottoms carefully. Press gently on sills to check for soft spots. Look underneath for corrosion on structural components. Check the MOT history for corrosion-related advisories or failures.

Suspension component wear and corrosion
High £200–£600 BP, BL, BR, BS

Outback models show consistently high rates of suspension component wear across all generations. MOT data reveals failures at up to 897.1 times the fleet average, particularly affecting bushes, ball joints, and drop links on the 3.0-litre models between 60-80k miles. The raised ride height and soft suspension tuning for comfort contributes to accelerated wear of rubber components and suspension joints.

Worn suspension components reduce vehicle stability and handling, particularly in emergency manoeuvres. Severely worn ball joints can separate causing wheel collapse and loss of control. Typical replacement costs for a full corner (shock, springs, bushes, ball joints) range £400-800 per side depending on the specific components required.

What to check

Listen for knocking, clunking or rattling over bumps during the test drive. Inspect the underside for corroded or cracked suspension components. Check the MOT history for suspension-related advisories, which often predict future failures.

3
CVT transmission failure
High £3,000–£4,500 BR, BS

The Lineartronic CVT transmission used in fourth and fifth generation Outbacks has documented reliability issues in the US market with over 200 NHTSA complaints mentioning transmission problems. Common failures include torque converter judder, complete transmission failure, and erratic gear selection. The CVT is particularly sensitive to fluid condition and overheating, with many failures occurring after 80,000 miles despite manufacturer claims of lifetime fluid.

CVT transmission failure typically requires complete unit replacement as internal components cannot be economically rebuilt. Replacement costs range £3000-5000 for a remanufactured unit plus fitting. Some failures occur suddenly without warning, leaving the vehicle immobilised. The car should not be driven if transmission slipping or juddering is present.

What to check

Test the automatic gearbox extensively in slow traffic, car parks and on hill starts. Feel for any juddering, hesitation or clunking during gear changes. Try repeated low-speed manoeuvres as this is where problems are most apparent.

4
Emissions system failure
High £150–£1,200 BR, BS

Failures occur at These failures typically manifest after 80,000 miles and are often caused by catalytic converter degradation, faulty oxygen sensors, or carbon buildup in the intake system.

Emissions failures will cause MOT test failure and prevent road use. Catalytic converter replacement costs £600-1200 depending on whether front or rear cat is affected. Oxygen sensor replacement costs £150-300 per sensor. Neglected emissions issues can damage expensive catalytic converters and lead to engine damage from incorrect air-fuel mixtures.

What to check

Check for any engine warning lights on the dashboard. Ask about the car's MOT emissions history — repeated failures suggest underlying issues. A pre-purchase diagnostic scan is especially worthwhile to check for stored emissions fault codes.

5
Electronic Stability Control malfunction
High £150–£800 BL, BR, BS

Diesel Outback models show MOT failures for ESC (Electronic Stability Control) system malfunctions at The fault typically manifests as a persistent ESC warning light on the dashboard and occurs most frequently on high-mileage diesel variants after 80,000 miles. Common causes include faulty wheel speed sensors, ABS pump issues, or steering angle sensor calibration problems.

ESC system faults cause immediate MOT failure. While the vehicle can typically be driven safely in normal conditions, stability control and traction control systems will be non-functional in emergency situations. Repair costs vary from £150 for sensor replacement to £800+ for ABS pump replacement depending on the specific fault identified.

What to check

Check all electrical functions systematically: windows, mirrors, lights, infotainment, heated seats, air conditioning. Look for any warning lights on the dashboard. A diagnostic scan before purchase can reveal stored fault codes.

MOT Weak Points

Based on 39k real DVSA MOT tests, the Subaru Outback fails more often than average on several items. The biggest outlier is coil springs broken at 41x the fleet average, followed by transmission joint, belt or chain worn (20x).

When viewing a specific car, check its MOT history for recurring advisories in these categories. See the full Subaru Outback MOT failure breakdown for data at every mileage point.

Running Costs

Routine servicing (oil and filter change every 10k miles) typically costs £80–£120 at an independent garage.

The bigger-ticket items to budget for include cvt transmission fluid (£200–£300).

The Verdict

The Subaru Outback has some well-documented weak points, including 1 safety-critical issue that demand careful checking. The right example, properly maintained, can still be a sound purchase — but cutting corners on the pre-purchase inspection is not advisable. The 2017-2019 fifth-generation models offer the best balance of modern safety tech, proven reliability, and value. For newer buyers, 2021 onwards (sixth generation) are the most refined. Avoid 2013 and 2015 models which had the most reported complaints. The 2005-2009 generation is a solid older choice if budget is tight.

Before committing, check the car's full MOT history, verify the service record is complete, and if possible arrange a specialist inspection. Enter any registration into our free report to see the complete picture.
