Repeatedly overcharging certain Porsche Taycans could lead to battery module degradation, leading to recall of 205 examples in the U.S.
Porsche Taycan drivers should exercise caution when charging, as the automaker has identified a problem in the high-voltage battery system of certain vehicles that has the potential to result in a fire. Unfortunately, the automaker has not yet determined the root cause of this issue.
The first indication of a potential problem arose in 2021 when Porsche received a report of a battery fire involving a Taycan. Following this incident, the automaker conducted an investigation and analyzed similar, undamaged battery packs for further study.
In 2023, the automaker became aware of two additional battery fires, each occurring shortly after the vehicle had completed charging. Although Porsche has not yet determined the exact cause, it suspects that repeated overcharging may, in some instances, damage battery cells, ultimately resulting in a short circuit.

Interestingly, even though it hasn’t yet determined a root cause for this issue, it reports that it has used machine-learning to find production clusters that may be affected by it. It also looked at real-time battery performance anomalies from vehicles in the field, and determined that a total of 205 American Taycans from the 2021-2023 model years must be recalled.
Unfortunately, there are no warning signs for drivers to detect this flaw. Those who want to see if their Taycan may be involved in this recall can check using the National Highway Traffic Safety Administration’s VIN look-up tool.
Porsche will also reach out to owners by mail starting on February 9. Their batteries will be checked, and any modules that may be dangerous will be removed and replaced at no cost. Owners who already paid to replaced their own modules may be entitled to reimbursement.
