Porsche 911 Carrera loose front differential fire risk

NHTSA campaign 20V381000 · Reported 2020-07-01 · Porsche Cars North America, Inc.

critical How serious is it? About this label

A fuel leak and fire are possible if the differential comes loose, so this is serious; Porsche has not told owners to park the car, but schedule the free repair promptly.

What's wrong, in plain English

The bracket that holds the front differential, the gearbox that sends power to the front wheels, may not have been tightened correctly. If it works loose, the differential can shift around and bang into nearby parts, including the fuel tank and the drive shafts. A damaged fuel tank can leak gasoline, and leaking fuel near anything hot or sparking can start a fire. Your dealer will remove the unit, check the bolt threads, look for damage, and reinstall or replace it.
