Known issues

Low
Wheel-detachment issue at launch (2023): wheel hub bolts could loosen on early bZ4X and Solterra. Both Toyota and Subaru bought back affected vehicles before issuing a fix. Pack itself was not implicated.
News
Low
DC fast charging caps at 100 kW (FWD) or 150 kW (AWD). Charge curve drops earlier than peer NCM packs; some owners report sub-50 kW above 80% SOC.
Owner-fleet data
Low
AWD trim has reduced range (~228 mi) versus FWD (~252 mi), and tow capacity is intentionally limited.
Owner-fleet data
Low
Conservative pack management — buffer is large, peak power output modest. Good for longevity, mediocre for performance.
