Two numbers, one recall

Every safety recall carries two identifiers. AMB9 is the number Porsche assigned in its own system: it is what appears on the owner letter, on the dealer’s service screen and on the repair order. 21V697000 is the number NHTSA filed the same recall under when the manufacturer reported it, and it is the one every federal record, this site included, is keyed on.

The repair is free by federal law for vehicles up to fifteen years old. Whether one particular vehicle is included is settled by its VIN against the manufacturer’s build list, not by its model year.

Both lookups check a VIN against the manufacturer’s own list and say whether the repair is still outstanding on that vehicle.

Common questions

Source: NHTSA, 49 CFR Part 573

Is AMB9 the same recall as 21V697000?

Yes. AMB9 is Porsche’s own number for it; 21V697000 is NHTSA’s. One recall, two references.

Which vehicles does AMB9 cover?

2020–2021 Porsche 911 and 1 other Porsche model, 11 vehicles by the manufacturer’s count. A recall covers a build range, so the VIN decides whether one particular vehicle is in it.

Does the AMB9 repair cost anything?

No. The manufacturer must remedy a safety defect at no charge for vehicles up to 15 years old from first sale.
