Scott Hirsch Law Group PLLC is currently investigating the 2026 Toyota bZ for issues relating to repeated 12V battery drain.

Toyota bZ Owners Report Repeated 12V Battery Problems

Toyota bZ owners report experiencing battery problems after the vehicle has been parked for relatively short periods, including overnight or for several days. Some owners report that replacing the battery did not resolve the issue, with the same problem occurring again after the replacement. Other owners have reported bringing their vehicles to dealerships multiple times while technicians attempted to identify the cause of the recurring issue, with some consumers documenting continued electrical activity while the vehicle was parked. These reports have raised concerns among owners about recurring problems despite attempts to address them.

Toyota Fails To Remedy

Many Toyota bZ owners have sought assistance from Toyota and its dealerships to address the recurring 12V battery drain. In response, Toyota has reportedly advised some owners to remove their vehicles from the Toyota App or disable certain connected services in an effort to prevent further battery drain. However, these measures do not address the underlying cause of the problem and may require owners to give up certain vehicle features. Toyota has reportedly continued to investigate the issue without providing a definitive repair. As a result, owners remain without a permanent remedy for the recurring problem.
