The official notice
Defect
On certain vehicles, the recall repairs completed by a Porsche dealer during recall APA7 (Transport Canada recall no. 2023-313) may not be effective. As a result, a second repair may be required. On certain vehicles, the high-voltage electric heater could fail. If this happens, you may experience reduced cabin heat, and the windshield defrost system may not work properly. Note: This recall replaces Transport Canada recall no. 2023-313.
Safety Risk
A windshield defroster that doesn't work may cause reduced visibility and increase the risk of a crash.
Remedy
Porsche will notify owners by mail. For certain vehicles, as an interim repair, Porsche will advise you to take your vehicle to a dealership to replace the passenger compartment high-voltage electric heater with a new part of the same design. When the final repairs are available, Porsche will notify owners by mail and advise you to take your vehicle to a dealership to replace the passenger compartment high-voltage electric heater with an improved part.
