This bulletin replaces bulletin Group 4 49/21 AMA3, dated March 31, 2021.
As of 2020 up to 2021

Hexagon clamping nut M12 x 1.5 on various threaded connections on the chassis
There is a possibility that clamping nuts, on which the thread was not manufactured
according to specifications, were installed on various threaded connections on the chassis
on the affected vehicles.
As a result, the required tightening torque was reached before the threaded connection was actually
tightened fully when installing the clamping nuts. There is therefore no guarantee that the affected
threaded connections will remain sufficiently tight over the service life of the vehicle.
Action required: Rework threaded connections on the front and rear axle.
On vehicles that have already been delivered to customers, the screwed components must also be
checked for damage.
Information
Please note that different screw positions on the front and rear axle must be reworked on the affected
vehicles.
The following specific campaign scopes have therefore been defined for reworking the threaded
connections. Every vehicle is clearly assigned just one campaign scope.
The relevantM12 x 1.5 fastening nutsmust be replaced on all affected vehicles, depending on the
assigned scope.
In addition, the relevant fastening screws must also be replaced.
On vehicles on which a component is screwed at the relevant screw point (e.g. actuator or
connecting link), depending on the assigned scope, the thread on the relevant component must be
checked and the component may also have to be replaced, depending on the result of the check.
On vehicles that have already been delivered to customers, the components that are screwed
together must also be checked for damage caused by relativemovements while driving as
installings, contact surfaces or bores on the individual components may have been damaged.
The relevant components may also have to be replaced, depending on the result of the check.

AMA3 – Reworking Various Threaded Connections on the Chassis (Recall Campaign)
Revision: This bulletin replaces bulletin Group 4 49/21 AMA3, dated March 31, 2021.
Model Year: 2021
Model Line: Taycan (Y1A, Y1B)
Concerns: Hexagon clamping nut M12 x 1.5 on various threaded connections on the chassis
Information: There is a possibility that clamping nuts, on which the thread was notmanufactured according
to specifications, were installed on various threaded connections on the chassis on the
affected vehicles.
As a result, the required tightening torque was reached before the threaded connection was actually
tightened fully when installing the clamping nuts. There is therefore no guarantee that the affected
threaded connections will remain sufficiently tight over the service life of the vehicle.
Action required: Rework threaded connections on the front and rear axle.
On vehicles that have already been delivered to customers, the screwed components must also be
checked for damage.
Information
Please note that different screw positions on the front and rear axle must be reworked on the affected
vehicles.
The following specific campaign scopes have therefore been defined for reworking the threaded
connections. Every vehicle is clearly assigned just one campaign scope.
The relevantM12 x 1.5 fastening nutsmust be replaced on all affected vehicles, depending on the
assigned scope.
In addition, the relevant fastening screws must also be replaced.
On vehicles on which a component is screwed at the relevant screw point (e.g. actuator or
connecting link), depending on the assigned scope, the thread on the relevant component must be
checked and the component may also have to be replaced, depending on the result of the check.
On vehicles that have already been delivered to customers, the components that are screwed
together must also be checked for damage caused by relativemovements while driving as
installings, contact surfaces or bores on the individual components may have been damaged.
The relevant components may also have to be replaced, depending on the result of the check.
Please note: All additional parts required to repair damage revealed by the test result are not part of
this campaign and must be determined independently in the Porsche Electronic Parts Catalogue (PET).
For warranty processing for these additional parts, see the section on  Technical Information ‘Warranty
processing’.

*******************************************************************************************************

This notice is sent to you in accordance with the National Traffic and
Motor Vehicle Safety Act. Porsche has decided that a defect that relates
to motor vehicle safety exists in certain 2021 Model Year Porsche 911
Carrera, Taycan, 718 Boxster, Spyder and Cayman vehicles. Our records
show that you are the current owner of a vehicle affected by this recall.
What is the issue?
There is a possibility that locknuts that were not manufactured to
specification were installed on threaded connections of your vehicle’s
suspension.
What should you do?
The necessary remedy parts are now available.
Please contact any authorized Porsche dealer
to schedule an appointment to have this recall
performed as soon as possible and to arrange
for Porsche-provided alternate transportation, if
necessary.
To find your nearest authorized Porsche dealer,
visit: www.porsche.com/usa
As a result, the specified tightening torque may not have been met on the threaded connection and therefore cannot be
guaranteed over the service life of your vehicle. A loose suspension component could in some cases detach, causing a
sudden loss of vehicle stability and control, and increase the risk of an accident.
What will Porsche do?
Porsche is conducting a safety recall to replace the affected suspension nuts and bolts. Authorized Porsche dealers will
also inspect surrounding components for damage, and replace damaged parts as necessary. Repairs will be performed free
of charge.
