Of the 32 electrical complaints filed for the 2012 Subaru Outback, here's the actual mileage breakdown — failures cluster heaviest at 100,000-125,000 mi.
Each bar shows the share of total complaints filed at that mileage range. Peak failure window highlighted. Some owners report problems earlier; some make it well past 150,000 miles symptom-free. Maintenance habits and driving conditions shift the curve as much as mileage alone.
No new NHTSA electrical complaint has been filed on this vehicle in over 5 years — the issue may be aging out of the active population.
The engine turning off unexpectedly can increase the risk of a crash. If a crash occurs under this condition, the air bag may not deploy, increasing the risk of injury.
The engine may inadvertently start and run for up to fifteen minutes. The engine may continue to start and stop until the fob battery is depleted, or until the vehicle runs out of fuel. If the vehicle is parked in an enclosed area, there is a risk of carbon monoxide build-up which may cause headaches, dizziness or, in extreme cases, unconsciousness and/or asphyxiation.
The manufacturer has issued service bulletins covering electrical on this vehicle — documented repair instructions, service campaigns, or warranty extensions sent to dealers. A TSB isn't a recall (it's not a free safety remedy), but it's the manufacturer acknowledging the issue and how to fix it.
This bulletin announces the new procedure and Warranty Fail Code for FirstTime air conditioning (A/C) performance concerns possibly resulting from an undetected A/C refrigerant leak.

The 2012 Outback's electrical system shows a pattern of cascading failures. Multiple warning lights—check engine, ABS, brake, cruise control, traction control, and stability control—flash or stay illuminated simultaneously while driving or parked. Battery resets provide temporary relief, but the problem returns within days or weeks. Some owners spent thousands on repairs (fan coil ~$1500, engine strap ~$3000) without resolution. Dealers often find nothing wrong.
Engine stalling is common during deceleration, hard braking, hill climbs, and gear shifts—sometimes with no warning light. At least one owner experienced complete loss of steering control. Subaru extended warranty coverage for torque converter defects on 2010–2015 models but capped it at 100,000 miles.
Key fob failure tied to RFID interference is location-specific: keys work fine in most areas but fail in certain zones. A Subaru corporate representative confirmed the interference occurs and stated nothing can be done about it.
Additional electrical gremlins include premature low-beam headlight burnout (every 3–6 months requiring tire removal for access), battery drain while parked, stuck electric parking brakes preventing movement, and loose or disconnected underhood wiring causing stalls.
Most concerning: multiple owners report engine fires. Dashboard lights flashing preceded smoke, metal clanking, and total vehicle loss in several cases. One fire was traced to the windshield wiper motor. These vehicles consumed themselves.

It's a meaningful issue. 32 complaints have been filed and the failure mode causes operational problems for owners. Repairs average $850.
Across the 18 complaints that reported odometer mileage, most electrical failures cluster between 50,000 and 125,000 miles, with the median around 90,000. A quarter of owners report trouble before 50,000; a quarter make it past 125,000. Maintenance history matters more than the odometer alone — this is the reported failure window, not a guarantee.
Independent shops typically charge around $850 for electrical repairs on this vehicle. Dealer pricing tends to run 20-40% higher. The exact figure depends on the specific failure mode, parts availability, and your local labor rates. If you're outside factory warranty, an extended service contract often covers this category.
