Subaru is facing a proposed class action lawsuit alleging that certain vehicles have a defective electrical system that can drain the battery even when the vehicle is turned off, potentially leaving drivers stranded without warning. Plaintiffs allege the issue has affected a wide range of Subaru models and that the automaker failed to properly disclose or resolve the problem despite years of complaints.
What is the problem?
The lawsuit claims that one or more electronic control modules in certain Subaru vehicles fail to enter a low-power “sleep” mode after the vehicle is shut off. Instead, these components allegedly continue drawing power from the battery, creating what’s known as parasitic battery drain, and over time, this excessive power consumption can cause the battery to fail prematurely.
According to the complaint, affected owners have reported repeated dead batteries, unexpected breakdowns, and vehicles that fail to start despite receiving replacement batteries. Plaintiffs argue that replacing the battery alone does not solve the underlying problem because the alleged electrical defect remains present within the vehicle’s systems.
The lawsuit further alleges that Subaru has known about the issue for years through technical service bulletins, warranty claims, and consumer complaints, yet failed to provide an effective long-term remedy. The proposed class action covers several Subaru models, including 2021-2022 Subaru Outback’s, 2021-2024 Subaru Forester’s, 2021-2023 Subaru Legacy’s, 2021-2023 Subaru WRX’s, 2021-2022 Subaru Ascent’s, 2019-2023 Subaru Crosstrek’s, 2019-2024 Subaru Crosstrek Hybrid’s, 2022-2025 Subaru Forester Wilderness’s and 2019-2023 Subaru Impreza’s.
What owners should do
Drivers who have experienced repeated battery failures, difficulty starting their vehicles, or the need for frequent jump-starts should arrange an inspection and keep records of all repairs, battery replacements, towing costs, and communications with Subaru. These documents may become important if issues persist or additional legal remedies become available.
Owners should also stay informed about developments in the proposed class action and monitor whether any future recalls, warranty extensions, or reimbursement programs are announced via the NHTSA website.
How Subaru owners can take back control
Being stranded unexpectedly because of a faulty battery can disrupt work, travel plans, and everyday responsibilities, particularly when the same problem returns after multiple repair attempts.
