3 known faults

71.4 kWh 218 ch intégrale (2022-2025)

  1. Wheels that can come loose (wheel hub bolt recall)

    Manufacturer recall

    As on the Toyota bZ4X, the wheel bolts could loosen, with a risk of a wheel detaching when cornering sharply, braking hard or accelerating. The repair consists of replacing the wheels and hub bolts. Subaru reissued a recall (1,182 vehicles from 2023 in the United States) because some repairs under the first recall had been done incorrectly. Check with the serial number that the recall work has been done.

    Fixed free of charge by a dealer and not counted in the reliability score: ask for proof the work was done (invoice, or a VIN check at a dealer).

  2. Disappointing fast charging

    Severity 1/3 · Annoying

    A heise test measured a power of around 60 kW at the start, rising to 105 kW, followed by a sharp drop beyond 80% charge. Some owners also report fast-charging sessions that fail to start or are interrupted, the cause (car or charger) remaining debated.

  1. Battery control unit software (2026 recall)

    Manufacturer recall

    A June 2026 recall concerns battery control unit software that can cause the electric drive system to shut down, with loss of drive power while driving; power steering and power brakes remain active. It targets 2025-2026 Solterras (around 4,757 vehicles in the United States, 395 in Australia); the fix is a free software update at a dealership. These figures do not directly concern France: check with a Subaru dealership.
