What is the 2010-2015 Subaru Outback CVT Valve Body / Internal Failure (10yr-100k Warranty Extension)?
Early Lineartronic CVT Outbacks (2010-2015) have documented internal CVT failures — most commonly valve-body faults, but also chain/pulley and pressure-control problems — that can cause harsh or delayed engagement, RPM flare, jerking, limp mode, or complete loss of drive. Subaru… Repairs typically run $0-$4,500. Severity: high.
What is the 2010-2014 Subaru Outback Windshield Wiper Motor Overheating / Bottom-Cover Melt — Crash and Fire Risk (Recall 16V694 / WTK-71)?
On 2010-2014 Legacy and Outback models, contamination inside the windshield wiper motor bottom cover can cause internal components to interfere. If an obstruction such as snow or ice prevents the wiper arms from returning to the park position, the motor can overheat: the wipers m… Repairs typically run $0-$150. Severity: high.
What is the 2010-2014 Subaru Outback Takata Passenger Airbag Inflator Explosion Risk (Recall TKB-20)?
Older Outbacks (part of the 2003-2014 Subaru population) are covered by the industry-wide Takata airbag recall for the FRONT PASSENGER airbag inflator. The ammonium-nitrate propellant can degrade after years of exposure to heat, humidity, and temperature cycling, causing the infl… Repairs typically run $0-$0. Severity: high.
What is the 2011-2019 Subaru Outback Excessive Oil Consumption?
The FB25 2.5L engine is known for excessive oil consumption, sometimes using 1 quart every 1,000-2,000 miles. Subaru extended warranty coverage and offered piston ring replacement for affected vehicles. Most common on 2011-2014 models. Repairs typically run $0-$4,000. Severity: medium.
What is the 2012-2019 Subaru Outback CVT Transmission Shudder/Hesitation?
The Lineartronic CVT can develop shudder, hesitation, or jerky operation, especially during light acceleration at low speeds. Subaru has updated CVT software multiple times to address these concerns. Repairs typically run $0-$4,000. Severity: medium.
What is the 2011-2019 Subaru Outback Head Gasket Issues?
While the FB25 has improved head gasket reliability compared to older EJ engines, some vehicles still experience head gasket failures. External oil leaks and coolant leaks can develop, particularly at higher mileage. Repairs typically run $1,200-$2,500. Severity: medium.
What is the 2011-2019 Subaru Outback A/C Compressor Failure?
The A/C compressor can fail, particularly on vehicles in hot climates with heavy A/C usage. Internal compressor failure can contaminate the A/C system with debris. Repairs typically run $600-$1,500. Severity: medium.
What is the 2010-2024 Subaru Outback Front and Rear Wheel Hub Bearing Failure Causing Droning/Humming Noise?
Owners across multiple Outback generations report premature wheel hub bearing failure, most commonly showing up between roughly 80,000 and 120,000 miles. The classic symptom is a low-pitched droning/humming or 'beehive' noise that begins around 45-55 mph and gets louder with spee… Repairs typically run $200-$700. Severity: medium.
What is the 2010-2019 Subaru Outback P0430 — Bank 2 (Driver-Side) Catalytic Converter Efficiency Loss, Often Preceded by Oil-Coked Rear O2 Sensor?
On the Subaru boxer engine, Bank 2 is the driver's side (cylinders 2 and 4). P0430 sets when the driver-side rear (downstream) O2 sensor tracks the front sensor too closely, telling the ECM the catalytic converter is no longer scrubbing exhaust efficiently. On the Outback this mo… Repairs typically run $250-$2,500. Severity: medium.
What is the 2010-2022 Subaru Outback P0455 — Gross EVAP Leak from Failed Purge Control Solenoid or Charcoal Canister Assembly?
P0455 indicates a large (gross) EVAP leak — the system can't hold pressure/vacuum at all during the self-test. Across the Subaru lineup (Outback, Forester, Impreza, Crosstrek) the standout pattern is the purge control solenoid valve failing due to internal seal degradation, which… Repairs typically run $30-$700. Severity: medium.
What is the 2010-2019 Subaru Outback P0011 — Bank 1 Intake Cam Timing Over-Advanced from Clogged AVCS Banjo-Bolt Filter or Faulty Oil Control Valve?
P0011 sets when the Bank 1 (passenger-side) intake camshaft is advanced beyond the ECM's commanded position — the AVCS phaser is stuck advanced or the ECM can't control it. On the Outback this is almost always oil-related: low or dirty engine oil, or the passenger-side intake oil… Repairs typically run $70-$450. Severity: medium.
What is the 2013-2019 Subaru Outback P0016 — Bank 1 Crank/Cam Correlation Fault from Low/Dirty Oil, Clogged Banjo-Bolt Filter Screen, or Failed AVCS Oil Control Valve?
P0016 means the ECM sees the Bank 1 (passenger-side) intake camshaft out of sync with the crankshaft. Subaru's variable valve timing (AVCS) is oil-pressure driven, so on the FB-series Outback (FB25/FB20) this code is highly sensitive to oil level and condition. The common Subaru-… Repairs typically run $70-$2,500. Severity: medium.
What is the 2005-2014 Subaru Outback P0741 — Torque Converter Clutch Stuck Off from Failed Lockup Solenoid, Bad Trans Ground, or Contaminated Fluid?
P0741 sets when the ECM/TCM commands the torque converter clutch to lock up but the expected reduction in converter slip doesn't happen. On the older automatic-transmission Outbacks (4EAT/5EAT, roughly 2005-2014) the dominant real-world causes are a failed torque-converter-clutch… Repairs typically run $150-$1,500. Severity: medium.
What is the 2010-2022 Subaru Outback Sunroof/Moonroof Drain Tube Clog Causing Interior Water Leaks?
Outbacks with a sunroof/moonroof commonly develop interior water leaks caused by clogged, kinked, or (on some 2020 Touring XT builds) factory-blocked sunroof drain tubes. Rather than draining out, water backs up in the sunroof frame and overflows into the headliner and down the A… Repairs typically run $150-$800. Severity: medium.
What is the 2013-2019 Subaru Outback FB25 Cam Carrier / Valve Cover Oil Leak?
The FB25 2.5L engine (2013+ Outback) has a widely reported oil leak from the cam carrier — the aluminum housing that holds the camshafts and functions as the valve cover on this engine. The RTV/gasket seal between the cam carrier and cylinder head degrades and weeps oil, which po… Repairs typically run $1,500-$3,800. Severity: medium.
What is the 2011-2019 Subaru Outback Catalytic Converter / Front Exhaust Pipe Failure Triggering P0420?
2.5L Outbacks are prone to premature catalytic converter degradation that sets a P0420 (Catalyst System Efficiency Below Threshold) check-engine light, often well before 100,000 miles. On some 2015-2016 2.5L Legacy/Outback models the front exhaust pipe assembly (which houses the… Repairs typically run $0-$2,500. Severity: medium.
What is the 2011-2019 Subaru Outback Front Strut/Suspension Noise?
The front suspension can develop clunking or squeaking noises, often from worn strut mounts, sway bar end links, or control arm bushings. This is common on vehicles with higher mileage or those driven on rough roads. Repairs typically run $150-$800. Severity: low.
What is the 2011-2019 Subaru Outback Windshield Cracking (Eyesight Equipped)?
Outbacks equipped with Eyesight can be prone to windshield cracking, possibly due to stress from the Eyesight camera mounting or windshield design. Replacement windshields require Eyesight camera recalibration. Repairs typically run $500-$1,200. Severity: low.
What is the 2010-2019 Subaru Outback Rear High-Mount (Third) Brake Light Gasket Failure Causing Cargo-Area Water Leaks?
The factory foam gasket behind the roof-mounted center high-mount stop lamp (CHMSL) on the tailgate deteriorates within a few years, allowing rainwater and car-wash water to seep past the light housing and run down the inside of the rear glass into the cargo area. This is a widel… Repairs typically run $15-$300. Severity: low.
What is the 2005-2022 Subaru Outback P0442 — Small EVAP Leak from Gas Cap O-Ring or Leaking Purge/Vent Valve?
P0442 means the ECM detected a small leak in the sealed evaporative-emissions system during its self-test. On the Outback the three usual culprits, in order, are: (1) the fuel filler cap — its rubber O-ring hardens and cracks with age, or the cap isn't clicked tight, or a non-OEM… Repairs typically run $20-$400. Severity: low.
