How 4,000 Fisker Owners Built an Open Source Car Company

When Fisker Inc. filed for Chapter 11 bankruptcy in June 2024, roughly 11,000 Ocean SUV owners were left holding $40,000-$70,000 vehicles losing their software brains. No more over-the-air updates. No more connected services. The manufacturer was dead — but the cars weren't.

What followed was remarkable. Owners formed the Fisker Owners Association, grew to 4,000 members, and began reverse-engineering proprietary software, hacking CAN bus networks, and building open-source tools on GitHub. Developers like MichaelOE created Home Assistant integrations exposing cloud APIs, while CAN bus files for the Ocean were published with DBC files for multiple buses running at 500kbps. Majd Srour published guides on decoding diagnostic trouble codes. The community negotiated key fob prices down from ~$1,000 through bulk purchases.

A $2.5 million deal with American Lease collapsed when they asked owners to cover 58% of operational costs without itemized invoices. Nikola, Canoo, and Arrival face similar fates — this won't be isolated. The question is whether we'll have systems in place to prevent functional vehicles from becoming e-waste when manufacturers disappear.
