Porsche became cognizant of the problem in 2022 when it received reports of "reduced insulation values" in a number of Taycan batteries. Investigations revealed that the main issue was the leakage of liquid into the batteries. To address this, a Teroson sealant was introduced into the battery production process by the supplier in September 2022.
However, in March, Porsche was informed that cars sold in markets outside the U.S. were still experiencing liquid intrusion issues despite the application of the Teroson sealant. This led the company to revise its battery production process, incorporating an improved Teroson sealant in May. Since that time, additional reports of low insulation resistance and liquid penetration into the batteries have been received.
The recall affects 4,777 Porsche Taycans from the 2023 model year, covering all body types.
Audi is also recalling 1,899 e-tron GT and RS e-tron GT models, specifically from the 2023 model year. Notably, both companies estimate that only about 200 cars, or roughly three percent of the total 6,676 vehicles being recalled, might actually have the issue. The recall is being termed as a global action by the companies.
Authorized dealers will conduct inspections to specifically check for liquid penetration in the battery packs. If tests reveal a "potential for leakage, the battery will be replaced," state Porsche and Audi. Neither company has reported any incidents related to this issue in the U.S., including fires, injuries, or fatalities.
Car owners can reach out to local dealerships to verify if their vehicle is part of the recall. Additionally, the cars come equipped with a built-in monitoring system that activates a yellow warning light on the dashboard if insulation resistance levels fall. If these levels continue to decline, a red warning light will come on. It's advisable not to wait for these warning lights before seeking dealership assistance.
