Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering engine 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 Service Information Bulletin provides the Service Manual Correction to the diagnostic procedure for DTC B2A16 (Immobilizer Key Collation Diagnosis).

The failure pattern owners describe
Owners of this 2008 Outback describe recurring engine stalls that happen unpredictably—sometimes 10 times in a day, sometimes a few times per week. When it happens, the dash lights all come on and the steering wheel locks. One owner went to the dealership three times, had the mass air flow sensor and battery replaced, spent over $1,000, and the stalling still happens. Subaru customer service told him the dealer can't fix it unless they can make it happen themselves.
Head gasket failure is the most consistent complaint. Multiple owners report leaks and failure in the 73,000–109,000 mile range—well before you'd expect major engine work. One owner had the vehicle regularly serviced under warranty the whole time but wasn't told about gasket damage until the warranty expired. Subaru acknowledged the defect as a known issue but refused coverage on some claims.
Several owners also report catalytic converter failure early on, cylinder misfires that come back within days of repair despite spending thousands in labor, and excessive oil leaking from head cover gaskets. Dealerships have charged owners thousands for parts and labor with inconsistent results. One owner noted the dealership told him a 2008 should not have head gasket failure but still wouldn't cover the cost.

Common questions
How serious is the engine problem on the 2008 Subaru Outback?
It's a meaningful issue. 13 complaints have been filed and the failure mode causes operational problems for owners. Repairs average $3,100.
At what mileage does the engine typically fail?
Across the 10 complaints that reported odometer mileage, most engine failures cluster between 63,046 and 98,000 miles, with the median around 75,815. A quarter of owners report trouble before 63,046; a quarter make it past 98,000. Maintenance history matters more than the odometer alone — this is the reported failure window, not a guarantee.
What does it cost to fix?
Independent shops typically charge around $3,100 for engine 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.
Are there any recalls related to engine?
No active recalls currently cover engine issues on this vehicle. The complaints filed represent owner-reported failures that haven't risen to the level of a manufacturer-issued recall — but they're still worth knowing about before you buy or budget for repairs.
