2016 BMW 330E Power Train Problems

Vehicle disengaged itself from gear while driving on hwy going between 75-85 mph. Failed to re engage into gear when stepping on accelerator causing vehicle to just coast and slow down as fast moving traffic (semis) we’re approaching. Construction zone didn’t have shoulders to pull aside which made situation worst. Car did accelerate after a few attempts. The car did illuminate a “unable to recharge batteries, stop carefully and contact your nearest service shop” just prior to the situation. Seems like the i3 models are currently under a class action lawsuit for a similar defect and I fear that given that these cars are designed similarly within the same years using the same parts that this could be a similar situation. I noticed that the car acted in this way once the battery level indicated under 3% charge on the dash.
