Recall: APB2 – Checking High-Volt Battery and Replacing if Necessary - Dec. 6, 2023

[Tooney]

Model Year: As of 2020 up to 2023

Concerns: High-volt battery

Cause: It could happen that under certain circumstances the seal between the battery casing and
battery cover on the high-volt battery on the affected vehicles is not sufficiently robust and
does not, therefore, reliably seal over the lifetime of the vehicle.

In the case of an insufficiently robust seal, under certain circumstances, liquid could penetrate inside the high-volt battery over time.

If a conductive liquid entering the battery exceeds a certain limit value, the insulating resistance
decreases. If the insulating resistance falls below a defined limit value over time, a yellow warning message is displayed in the vehicle.

If the insulating resistance continues to fall below a defined limit value in the course of time, a red warning message is displayed in the vehicle.

If customers do not contact a Porsche Center despite a red warning message in the vehicle, and a sufficient amount of conductive liquid has accumulated in the high-volt battery, electric arcs could build up that could heighten the risk of a thermal event.

Action: Check high-volt battery and replace it depending on the test result.
