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.

Backing into the center of my 2-car garage, half-way into the door, the car slammed on the brakes, displayed a large BRAKE warning and, on the 360 degree image, I saw a red "bar" to the immediate left of the driver's door. I thought I'd hit something, although I was still 20 feet from the back wall and there was at least 6 feet completely open on each side of the car. I pulled forward and it immediately slammed on the brakes again. I backed up and it slammed on the brakes again. I pulled forward and it slammed on the brakes again. Finally,…

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 vehic…

The 12V battery in my 2026 Toyota bZ unexpectedly went dead, leaving the vehicle completely unresponsive. The vehicle could not be powered on or driven. There was no prior warning. Upon google search, there are several posts on websites like reddit and toyota owner forums with reports of the same exact issue.

Vehicle purchased late March. Since then, the 12V gets completely drained to 0% over the weekend. This is a biweekly problem. Vehicle taken to dealership, they were not able to replicate problem. Dealership claims battery and vehicle perfectly fine. 12V battery continues to get discharged. This issue puts the customer at risk of being stranded on trips. No warning lamps or symptoms before battery dies making vehicle completely inoperable. Research online and owner forums clearly show a large number of owners having the same issue with this defe…
The vehicle suffers from an overnight parasitic 12V battery drain caused by a continuous cloud activation/software communication loop involving the Data Communication Module (DCM) and telematics system. The vehicle has gone completely dead and required jumping on three separate occasions. The issue was inspected and documented on a service invoice by an authorized dealership, which confirmed the battery itself tested good and recommended disconnecting the mobile application link due to the DCM cloud activation causing battery depletion. The rec…
There is a foul smell emanating from the window areas of the vehicle after rain. The more rain, the more pronounced the odor. It smells similar to cat urine. I have been able to reproduce it many times, after it rains. I was reading online that the smell is caused by mold/mildew which is a huge safety concern. I had also read that this is somewhat of a common issue caused by the type of weatherstripping in use on the vehicle. When I called the dealership they were unaware of any issues concerning an odor around the windows after rain. I…
The 12 volt battery exhibits a consistent parasitic drain. This is intermittent, but results in the vehicle failing to start. The failure to start is an issue because it is happening frequently and could endanger individuals who live in rural areas or areas with cold or hot climate. This issue has happened to us multiple times and Toyota has not recalled or provided guidance to its dealer service network. Many effected owners have a diagnostic data backed theory that links the drain on the 12 volt battery to Toyota digital communication modu…
SUPPLEMENT TO ODI COMPLAINT 11758090 (filed 8/19/2026). Two corrections, an identified component, and a verified manufacturer remedy. Full narrative attached. CORRECTIONS. (1) The prior 12V battery was replaced 5/29/2026, not June 2026; invoice 569207 is correct. (2) The complaint attributed the drain to an armed charging schedule. That was a proxy, not the cause. The trigger is ANY vehicle wake -- key-fob approach at ~8 ft, end of drive, or converter pulse -- which arms a timer of exactly 180 minutes, after which a 0.87-0.9 A sawtooth dischar…
Complete months in the latest six months with at least 10 complaints, at least twice the preceding 12-month average, and at least three square-root deviations above that average.
This is a descriptive screening rule, not a statistical defect finding. Publicity and reporting changes can increase submissions.
No complete months meet the spike thresholds for this selection.
Equal-age model-year comparison
Model-wide cumulative reports during the first three or five calendar years, starting with the model year (age 0). Only fully elapsed windows are compared.
No selected model years have a complete observation window. Choose an eligible year or a shorter window.
Incident date is preferred when valid and no later than filing; otherwise filing date is used. Model year approximates age. Equal observation time does not adjust for sales, distance driven or reporting delays. One complaint linked to multiple model years can appear in each cohort.
