Check if your Porsche has a Recall

 


Chronology :

Beginning in 2022 Porsche became aware of a limited number of non-U.S. field cases involving reduced insulation resistance values, some of which indicated liquid intrusion into the battery. None of these incidents resulted in a fire or thermal event of Porsche vehicles. In September 2022 a Teroson sealant was incorporated into the battery production process for Taycan vehicles in an effort to increase battery sealing robustness.

In March 2023 Porsche began receiving reports of reduced insulation resistance values in vehicles with the Teroson sealant outside of the U.S., and in April 2023 one incident in the U.S. was reported.

Porsche continued investigating the cause of the liquid intrusion and concluded that a further enhanced Teroson sealant should be added to the battery. The enhanced Teroson sealant was added in May 2023 in the production process of the supplier. There have been no reports of liquid intrusion in vehicles with the enhanced Teroson sealant added.

Porsche continued to receive reports of reduced insulation resistance values in vehicles with the original Teroson sealant. In July and August 2023 two additional U.S. incidents were reported. These incidents were reported when reduced insulation resistance values lead to warning messages displayed in the vehicle causing vehicle owners to bring their vehicles to workshops for repair, at which time liquid in the battery was detected. None of these incidents involved a fire or thermal event. On August 25, 2023, in an abundance of caution Porsche has determined to conduct a recall of these vehicles with the original Teroson sealant.
