AMA9 – Replacing Threaded Connections on Rear Trailing Arm (Stop Delivery/Recall Campaign)

 

Model Line:

Cayenne (9YA)/Cayenne Coupé (9YB)

 

Model Year:

2021

 

Concerns:

Rear-axle trailing arms

 

Information:

There is a possibility that clamping nuts that were not manufactured within the specified parameters were installed on the rear-axle trailing arms on the affected vehicles.

This can result in stress corrosion cracking on the clamping nuts, which may cause the clamping nuts to break over the service life of the vehicle. A broken clamping nut can result in increased play between the trailing arm and wheel carrier and as a result, vehicle handling may suddenly be impaired.

 

Action required:

Replace clamping nuts on the rear-axle trailing arms.

Affected Vehicles:

Only vehicles assigned to the campaign (see also PCSS Vehicle Information). This campaign affects 1,568 vehicles.
