Bulletin 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.
About Technical Service Bulletins
A Technical Service Bulletin (TSB) is a document issued by a vehicle manufacturer to its dealers, describing a known issue with a specific vehicle or set of vehicles and the recommended procedure to fix it. Unlike recalls, TSBs are not mandatory and are typically only performed if an owner reports the related issue. However, TSBs can be an indicator of common problems with a vehicle.
