# Service bulletin SIB610222

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

- Type: Service bulletin
- NHTSA id: 10214983
- Published by NHTSA: 2022\-07\-05
- Manufacturer's number: SIB610222

## NHTSA's summary

BMW AG is conducting a Voluntary Service Action on certain Model Year 2019\-2020 BMW Plug\-In HybridElectric \(PHEV\) vehicles that were produced between March 25, 2019, and October 17, 2020. Analyses of transmitted teleservice data indicate abnormalities in the "balancing" of the cells within one or more of the high\-voltage battery cell modules. This could possibly cause a loss of performance of the corresponding modules, such as faster ageing, shorter range, or possible operating failure.
