Porsche Cars North America is recalling various Taycan models from the 2020 through the 2023 model years because the high-voltage battery may undergo a short circuit without warning within the battery modules of its first four-door electrified SUV.*
According to the required safety defect filing released by the National Highway Traffic Safety Administration today, the hybrid battery modules were produced by LG energy Solution in Wrocław, Poland.
An owner notification letter will advise that affected vehicles should only be charged to a maximum of 80% of the battery capacity until the affected modules in the high-voltage battery will be replaced.
Chronology
- In 2021 Porsche became aware of a report of a single vehicle battery fire that occurred shortly after charging. Porsche investigated this incident and began obtaining comparable undamaged batteries from the field for analysis.
- In 2023, Porsche became aware of further instances of battery fires in Taycan vehicles after charging.
- December 2023 – Although the root cause analysis was still ongoing, on 6 December 2023 Porsche determined that a safety-related defect exists in the identified vehicles (manufacturer recall identification code APB5). Porsche continued investigating this issue together with the battery cell/module manufacturer, using in particular data analytics and hardware analyses.
- With this additional investigation and analyses on 13 March 2024 Porsche determined that a safety-related defect exists in additional vehicles identified via data analytics and hardware analyses.
- As there are different batches of potentially affected Porsche Taycan vehicles which require different remedies, Porsche decided to conduct two different recalls on 13 March 2024 (manufacturer recall identification code ARA4 and ARA5): ARA4 applies to a vehicle population where Porsche has sufficient vehicle battery data. ARA5 applies to a vehicle population where Porsche does not or not yet have access to sufficient vehicle battery data.
- Owner notification letters are expected to be mailed 17 May 2024. Dealers have already been notified. Owners may contact Porsche customer service at 1-800-767-7243 about Porsche recall ARA4 or ARA5. Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.nhtsa.gov about NHTSA 24V215 or 24V217.
