NHTSA Complaint #11680030 — 2023 SUBARU SOLTERRA

Component/System that failed: Battery range performance and charging system on 2025 Subaru Solterra. Vehicle is available for inspection upon request. Safety risk: The vehicle loses significant range after charging, creating a real risk of being stranded in traffic, on the freeway, or in remote locations — even during short in-town trips. This could leave me without power in unsafe conditions. Problem details: On one occasion, after charging for 48 minutes at a Level 3 DC fast charger, I gained only 53 miles of range, then lost 17 of those miles in just 2 miles of driving. On other occasions, I have lost 21 miles in 1 mile of driving and 27 miles in 6 miles. No climate control was in use during some of these tests. Reproduction/confirmation: The problem occurs repeatedly and has been documented with photographic evidence. Gresham Subaru has claimed this is “normal,” but it is not consistent with expected EV performance. Inspection history: The vehicle has been looked at by Gresham Subaru but no thorough diagnostic or battery inspection has been completed. Subaru of America is aware of the issue. Warning signs: No warning lamps, error messages, or other dashboard indicators appear before or during the loss of range. The issue began shortly after purchase and has continued despite software updates.
