Subaru Repair & Service in Union City, CA: Subaru-Only Maintenance, Diagnostics & Performance

Union City Subaru owners don’t have to rely on dealerships for expert service. Servicing your Subaru outside the dealership does not void your factory warranty—as long as factory requirements are followed. That’s exactly how we operate at Garage One.

We’re Subaru-only experts based in Campbell, not a dealership. Every appointment is scheduled in advance for focused, Subaru-specific care.
