What's wrong?
On the 2020 Porsche 911 Carrera, the front axle differential is the gear unit that helps send engine power to the front wheels on the all-wheel-drive system. A threaded bracket holds that differential to the front-axle cross member, the structural support that keeps the drivetrain in the right position.
In recall 20V381, that bracket was not fully tightened during supplier assembly. One of two threaded joints received only the first tightening torque instead of the final specified torque. If the bracket loosens, the differential can move and contact nearby parts. Porsche's testing found that direct contact between the front drive shafts and the fuel tank can damage surrounding components.
Owners reported loud knocking noises and vibrations from the front of the vehicle while driving. Those sounds or vibrations are the warning sign to take seriously and have the vehicle checked by a Porsche dealer.

What happens at the repair
At the dealer, a Porsche technician removes the front axle differential, checks the screw threads, and inspects nearby components for damage. Based on that inspection, the technician reinstalls the front axle differential or replaces it, using new screw joints torqued to Porsche's required specification. Parts and labor are covered under the recall. Porsche has a general reimbursement plan on file for owners who already paid for this related repair. Bring documentation of the paid repair to the service desk or contact Porsche customer service before your appointment.
