Toyota and Subaru are both being sued over battery failures in their respective bZ4X and Solterra electric vehicles. For many shoppers considering an EV, a failing battery represents the ultimate nightmare, given how staggeringly expensive a replacement can be.
Battery reliability is central to consumer confidence in electric vehicles, making these lawsuits especially damaging. The legal challenges threaten to reinforce the very fears that keep cautious buyers from embracing EVs in the first place.
I have a 2024 Bz4x and had the same problem after I subscribed to an app that monitored my electric usage. Once I deleted the app, I no longer have problems with a depleted 12 volt battery. The only reason I can think of as to why the app caused this problem is that it could have awakened the car too often. In any case, problem solved. The Bz4x is a great EV.
