4/5 Overall
NHTSA 5-Star Safety Rating
Excessive oil consumption is the dominant theme across 2011 Forester complaints, with owners widely reporting the need to add a quart or more of oil between fill-ups, often accompanied by a burnt oil smell. The engine category draws the most complaints overall, and beyond oil consumption, owners describe stalling or unexpected shutoffs when slowing down, with check engine lights that persist even after repairs like coil replacements. The airbag system generates the second-highest complaint volume, though the specific symptoms owners describe vary. Vehicle speed control complaints include reports of unintended acceleration, typically described as the car surging without driver input during low-speed maneuvering. A smaller number of reports describe smoke or fire originating from the engine compartment, though these appear less frequently than the oil consumption and stalling patterns.

With Injuries
By System
The 2011 Subaru Forester has 14 recalls, the most serious being a passenger-side airbag inflator that can explode and send metal fragments into the cabin, posing a serious risk of injury or death to occupants.
Because multiple recall filings cover this same airbag inflator defect across different model years and registration regions, this is treated as one underlying issue, but it accounts for the majority of open recalls on this vehicle. On the electrical side, turbocharged models have a relay that can fail and allow the secondary air injection pump to run continuously, overheat, and melt, raising the risk of a fire under the hood. There is also a concern with replacement ignition switches: a small internal spring can break and weaken the switch, causing the engine to shut off unexpectedly while driving and leaving the airbags less likely to deploy in a crash. The exterior puddle lights on some vehicles can allow moisture into the circuit board or connector, potentially causing a short.
On the restraint side, the front seatbelt force-limiter may not function correctly in a crash, reducing how well the belt holds an occupant. The rear center seatbelt's automatic locking retractor can also fail to lock properly, meaning a child safety seat installed there may not be held securely.
