The contact owns a 2023 Toyota BZ4X. The contact received notification of NHTSA Campaign Number: 25V577000 (Visibility); however, the part to do the recall repair was unavailable. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The contact stated that the A/C unit was not working properly. The vehicle was taken to the dealer, and it was determined that the compressor had failed and caused the AC unit to fail to perform as needed. The compressor was causing a loud electrical humming sound inside and outside the vehicle. The vehicle remained at the dealership waiting for approximately one and a half months for the repair. The failure mil…
I was driving during heavy rain when I heard and felt a big thump. I wasn't sure what happened as I did not hit anything in the road. I was in my neighborhood driving at low speeds (<30mph). When I got home, I realized my fender liners and lower splash guard of my car were missing. I went back out to retrieve these pieces of my car, and it appeared the fender liners and the splash guard got torn off my car without impact with anything, as nothing was in the road near it. I was going to attempt to reconnect them but the plastic clips on the front bumper also ripped off, making this a very expensive repair requiring bumper replacement and sensor recalibration. This obviously could put ot…
While operating my 2024 Toyota bZ4X at very low speed on the road , I observed a stationary shipping container directly ahead and applied the brake pedal with maximum force approximately 4 seconds before contact. I held the brake pedal at full pressure continuously. I never touched the accelerator. The vehicle came to what appeared to be a complete stop then continued to advance and made physical contact with the container despite my maintained maximum brake input. The vehicle's own ECU-recorded Freeze Frame Data (retrieved by an authorized Toyota dealer using PCS Data Viewer) confirms the following at the time of the event: Driver brake pedal torque was at sensor saturation (4,048 Nm â …
The vehicle experienced a sudden, catastrophic brake-by-wire system failure while operating in one-pedal driving (Regeneration Boost mode). While decelerating at a low speed behind an 18-wheeler semi-truck, the vehicle failed to continue slowing down. I immediately depressed the physical brake pedal, but the vehicle completely ignored the foot pressure. The pedal and braking system became completely unresponsive, and the vehicle kept rolling forward uncommanded. Despite keeping the brake pedal fully depressed, the vehicle did not decelerate, resulting in a front-end low-speed collision with the metal rear bumper of the semi-truck. Because the collision occurred at a very low speed, the o…

There were no warning lights. The failure had occurred 3 times. When attempting to start the vehicle one day, the vehicle failed to start. The tow company came and provided a jump-start, and then advised the contact to drive carefully, but if it failed to go in reverse. The next morning, the tow company's mechanic came again and confirmed…

While driving on the highway under normal conditions with no road hazards present, the engine under cover (part #51441-42210) detached from my vehicle and the bumper clips broke, causing both the under cover and bumper to become damaged and requiring replacement. There was no collision, no debris, no pothole, or any other road hazard involved. The failure occurred solely under routine highway driving conditions. Upon taking the vehicle to my Toyota dealership, the service team acknowledged this is a known and recurring issue with the bZ4X model. Research and owner forums confirm multiple 2023 bZ4X owners have experienced the identical failure â undercarriage cover and bumper detachment und…

In complaints filed with NHTSA for model years 2023–2025, owners most often name: electrical system, unknown or other, structure. 50 complaints are on record.
No. A complaint is an unverified report from an owner. A technical service bulletin (TSB) is the manufacturer telling dealers how to fix a known issue; it is not a safety recall and is usually covered only under warranty. A recall is a formal safety action, and its repair is free.
File a vehicle safety complaint at NHTSA.gov. NHTSA reads every report, and patterns of complaints are what open defect investigations and, eventually, recalls.
