Porsche Taycan battery short circuit can cause fire

NHTSA campaign 24V732000 · Reported 2024-10-01 · Porsche Cars North America, Inc.

critical How serious is it? About this label

Very serious — this is a fire risk; the notice does not tell owners to park outside or stop driving, but follow Porsche's advice to charge only to 80 percent and get your car checked right away.

What's wrong, in plain English

The large battery that powers your Taycan can short-circuit inside one of its sections, and a short in a battery this big can start a fire. Porsche is watching data that cars send in online and will contact owners whose battery looks suspect, telling them to charge only to 80 percent until it is replaced. Dealers install new monitoring software as the permanent fix. If your car does not send data, the dealer will test it and replace the battery section if needed.

What you should do

1. Check your VIN at nhtsa.gov/recalls to confirm your car is covered (owner letters went out August 6, 2025). 2. Call your Porsche dealer or Porsche at 1-800-767-7243 and ask about recalls ARB6 and ARB7. 3. Charge only to 80 percent until the work is done — the software, testing, and any battery replacement are free.
