**Report to NHTSA â’ 12-Volt Battery Issue in Toyota BZ4X** **Vehicle Information:** — **Make & Model:** Toyota BZ4X — **Issue:** 12-Volt Battery Drain **Description of the Problem:** I have been experiencing repeated issues with the 12-volt battery in my Toyota BZ4X. If the vehicle is not driven for one or two days, the battery depletes, requiring a jump-start to operate. I have taken the car to the dealership for inspection on two separate occasionsâ’once in November and again recently. On both visits, the dealer was unable to identify any issues. However, despite these inspections, the problem persists. Most recently, after taking the vehicle to the dealership, the car once again failed to start the following day and required another jump-start. **Safety Concern:** This recurring battery failure presents a significant safety risk, particularly if the vehicle becomes inoperable in a remote location or in an emergency situation. The inability to start the car reliably raises concerns about potential hazards, especially in extreme weather conditions or areas with limited access to assistance. **Request for Investigation:** I urge the NHTSA to investigate this issue further, as it affects the reliability and safety of the vehicle. A resolution is necessary to ensure that the 12-volt battery functions as intended without leaving drivers stranded.
