2026 TOYOTA BZ Electrical System Problems

I am writing to formally advise Toyota Customer Relations of significant, unresolved performance and safety issues regarding my 2026 Toyota bZ, purchased new on February 14, 2026. Despite having only 976 miles on the odometer, this vehicle is currently demonstrating a battery state of health (SOH) of 82.7% and a maximum range of only 140 miles at 100% charge—even in moderate 40-degree temperatures. Description of Technical Failures: Battery & Range: The vehicle provides a maximum range of 140 miles at full charge. On an 80-mile roundtrip commute, I am forced to drive without cabin heat to ensure I can return home without a mid-trip recharge. Internal diagnostics currently show an 82.7% battery health, which is unacceptable for a vehicle less than a month old. Regenerative Braking: The regeneration system is not functioning properly, failing to recoup energy as designed. Infotainment & Safety: I have experienced consistent Bluetooth disconnections, audio drops...

I purchased a new 2026 Toyota bZ4X on December 30, 2025. The dealer represented that the vehicle could charge in approximately 30 minutes at public fast-charging stations. In real-world use, the vehicle cannot be charged as represented and is only usable at one local charging station with a special adapter that was not disclosed or provided at the time of sale. As a result, the vehicle cannot be reasonably used for daily transportation and creates a risk of being stranded or unable to travel when needed. I believe this is a significant vehicle usability concern affecting safe and reliable operation.

What component or system failed or malfunctioned, and is it available for inspection upon request? The vehicle experienced a failure of the high-voltage battery control system (Battery ECU / main battery control module), resulting in loss of propulsion. The vehicle is currently at an authorized Toyota dealership and is available for inspection upon request. How was your safety or the safety of others put at risk? The vehicle shut down while driving, causing an unexpected loss of power and propulsion. This created a dangerous situation due to the inability to safely maintain speed or maneuver in traffic, increasing the risk of a collision or death. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes. An authorized Toyota dealership diagnosed the issue and confirmed that the Battery ECU / main battery control module required replacement. Has the vehicle or component been inspected by the manufacturer,...
