The pre-facelift Subaru Solterra (2023-2025) suffers from severe thermal throttling in its battery management system, causing DC fast charging speed to drop dramatically and often requiring up to an hour to reach 80% charge. Additionally, the system limits drivers to a maximum of three DC fast charging sessions per day to protect the battery, which significantly reduces practicality for long-distance travel. The 2026 model year refresh addressed this with an improved charging curve and a battery pre-conditioning feature, but no permanent retrofit for earlier models is documented.
