What's wrong?
The rear upper control arms on the 2020 Porsche Taycan are suspension links that help hold each rear wheel in the right position as the suspension moves. The screw connections fasten those arms to the wheel carrier and the chassis subframe, so the rear axle keeps its intended alignment under load.
On affected Taycans, those screw connections were not installed to Porsche specifications. The problem traces to a production process adjustment that was not properly safeguarded. If a connection is loose, the control arm can move against its mounting points instead of holding the wheel carrier firmly in place.
There is no guaranteed warning sign before failure. Owners can hear abnormal noises from the rear suspension when the affected components move.

What's the safety risk?

What happens at the repair
At the dealer, a Porsche technician replaces the screw connections for the front and rear upper control arms on the rear axle. Parts and labor are covered under the recall. Porsche is not offering a separate reimbursement program because the affected vehicles remain covered by the Porsche New Car Limited Warranty. If you already paid for related work, ask the service desk how that warranty coverage applies to your paperwork.
