Porsche Taycan and Audi E-Tron GT Recalled for Poorly Sealed Batteries

In a modern EV, the battery is one of the most expensive components in the car. Protecting it from harm is thus a primary concern for automakers. Porsche and Audi have recently tripped up on that front, leading to a recall to rectify the problem.

As covered by Elektrek, the recall concerns Porsche Taycan and Audi e-Tron GT models from the 2023 model year. The issue concerns the sealing of the battery, which can allow potentially damaging water intrusion to occur. In these cases, affected vehicles may display a warning message due to the risk of damage caused by liquid entering the battery. Affected cars were built from September 23, 2022 to August 25, 2023. The recall concerns 4,777 Taycan models and 1,899 e-Tron GTs, with the companies expecting roughly three percent of that population to be subject to the water ingress issue.

Liquid ingress poses a serious risk to an electric vehicle's battery. It can cause internal arcing with the potential to cause a "thermal event," which can involve overheating or even a battery fire. It can also cause corrosion to internal battery components which could lead to damage over a longer time period.
