Recalls and safety

The 2017 and 2018 Chrysler Pacifica Hybrid, 16,741 vehicles, fires while parked with the ignition off. And 2020 to 2021 BMW plug in hybrids, where debris entered cells during production.

Not confirmed. In both recalls the federal record names the automaker, not the cell supplier. The Samsung SDI attribution is press sourced and should be cited separately. Reports that Stellantis is exploring an exit from their joint venture are just that. No decision has been announced.

Vehicles using their cells

confirmed: Rivian R1T and R1S, 2170 cells
confirmed: BMW, under contract to 2031
reported, and Porsche declined to comment: Porsche Macan Electric, Korean market

Confirmed means an automaker or supplier statement, a filing, or a recall document named it. Reported means press or analyst claim only. Several automakers dual source, so one model can carry cells from more than one maker.

Plants

operating: Ulsan, God, Xi'an, Tianjin, Malaysia and Vietnamoperating
storage facility operating: StarPlus Kokomo Indianastorage facility operating, two cell plants building
building: New Carlisle Indianabuilding, now wholly Samsung SDI

Read 16 September 2026. Plant status is recorded as operating, building, announced, paused or cancelled, and is not softened.
