The Current Claims
A class action alleges that many 2019-2025 Subaru models have an electrical-system defect that prevents certain electronic control modules from entering a low-power “sleep” state, causing a parasitic drain that can leave the battery dead and the car unable to start. The suit alleges Subaru has known about the problem since at least 2014 through a stream of consumer complaints, yet has not fixed the root cause — leaving owners to pay repeatedly for batteries, jump packs and repairs.
A dead battery is an inconvenience once; a recurring drain that survives a new battery is a defect, which is the crux of the claim.
The Prior Settlement
An earlier settlement, approved in 2023, covered certain 2015-2020 Subaru models and required Subaru to cover the cost of a first battery replacement within a set time and mileage. Owners in the newer lawsuit argue that deal addressed the symptom — a dead battery — rather than the underlying electrical defect, so replacement batteries eventually fail the same way as the parasitic draw continues.
That distinction — treating the symptom versus the cause — is exactly what the newer case seeks to force.
What Owners Should Know
Owners experiencing repeated dead batteries should document each occurrence, replacement and repair with dates and costs, and report the issue to Subaru and to NHTSA. That record supports both a warranty argument and inclusion in the litigation, and repeated complaints are part of what builds a defect case.
