Period mentioned: 2020–2025
Symptoms: Usually none. In rare cases, a battery fire, including when parked.
Possible cause described: Some cells may have a damaged internal separator. Stellantis has run several recalls since 2023, the latest in the US for about 320,000 cars; until a fix is available it asks owners not to charge them and to park outside. The repair is a software update and, if needed, a battery replacement.
