Subrogation and the Cargo-Manufacturer Question
If a defective EV starts a fire, can the hull insurer subrogate against the manufacturer? The answer is moving — and the case law is being made now.
After a casualty, hull underwriters pay first and ask questions second. The question they ask is whether anyone else can be made to pay them back. In the EV era the most interesting answer is "the cargo manufacturer" — and the legal infrastructure for that subrogation route is still being built.
What the route looks like in theory
- Hull insurer pays the owner.
- Owner assigns subrogation rights to the insurer (standard policy provision).
- Insurer pursues the cargo manufacturer for product liability — a defective EV battery as the proximate cause.
- Recovery, if any, returns to the insurer's claims reserve.
Why it is hard in practice
Proving a specific defective vehicle was the ignition source in a fully burned PCTC is forensically difficult. Establishing manufacturer liability under product-liability frameworks designed for road-traffic context is novel. And bills of lading and carriage contracts can limit cargo-side claims in ways that complicate insurer recovery. MOL's litigation against Volkswagen over Felicity Ace is testing several of these dimensions simultaneously.

Questions, answered
Can a hull insurer subrogate against an EV manufacturer after a fire?+
In theory yes: the hull insurer pays the owner, takes assigned subrogation rights, and pursues the manufacturer for product liability with a defective battery as the proximate cause, with any recovery returning to the claims reserve. In practice the legal infrastructure for that route is still being built.
Why is manufacturer subrogation hard in practice?+
Proving a specific defective vehicle was the ignition source in a fully burned PCTC is forensically difficult; establishing manufacturer liability under product-liability frameworks designed for road traffic is novel; and bills of lading can limit cargo-side claims. MOL v. Volkswagen is testing several of these dimensions at once.
Why does the subrogation question matter for underwriting?+
Today the cost of EV casualties is absorbed by hull and P&I. If subrogation routes back to manufacturers become viable, they would shift the underwriting calculus dramatically by relocating where the loss ultimately sits. The case law is the bottleneck.

When a PCTC declares General Average, every cargo owner contributes proportionally to the loss. Most don't grasp this until the demand letter arrives.
