Model Line:
Taycan (Y1A)

Model Year:
As of 2020 up to 2021

Concerns:
Threaded connections on upper control arms of the rear axle

Information:

Therefore no guarantee that the affected threaded connections will remain sufficiently tight over the service life of the vehicle.

Action required: Replace threaded connections on control arm on rear axle.

 

Information

On vehicles that have already been delivered to customers, the components that are screwed together must also be checked for damage caused by relative movement while driving as fittings, contact surfaces or bores on the individual components may have been damaged.

Depending on the result of the check, the affected components may also have to be replaced.

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 theTechnical Information ‘Warranty processing section’.

Affected Vehicles:

On November 15, 2021, Porsche decided to recall the subject vehicles to remedy this issue.
