There are 2 owner-reported engine complaints for the 2025 Subaru Legacyin NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
Less than 500 miles cabin fills with engine fumes - smells like exhaust/crank case vapors - especially at idle and with outdoor air damper open on HVAC. If you open hood the engine bay smells like gas fumes. Upon inspection looks like passenger side exhaust manifold is leaking with splatter marks on exhaust manifold - fire and health hazard. Subaru corporate in past has been poor to deal with and makes statements like our dealers are independent and we have no control over our dealers when trying to get them to take action. Now I'll have to battle this out and likely with BBB claim. I have Asthma and cannot drive this vehicle with this smell.
