Recalls on the 2024 Toyota BZ4X

A complaint is one owner's allegation. A recall is the point at which the manufacturer or a regulator agreed the defect is real and dangerous enough to fix for free — however old the car is.

United States — NHTSA

25V744000

Recall 2025594 99,178 units in Canada

Visual System

Issue: Under certain conditions, a software problem could cause the rearview camera image to freeze or not to display. If this happens, the rearview image may not display when the transmission is shifted into reverse. Canadian regulations require the rearview image to display when the vehicle is reversing. Note: This recall only affects certain vehicles equipped with a panoramic view monitor system. Safety Risk: A rearview camera image that doesn't display correctly could reduce a driver's ability to see behind the vehicle while backing up. This could increase the risk of a crash. Corrective Actions: The company will notify owners in writing and advise you to take your vehicle to a dealership to update the parking assist ECU software.

Recall 2025451 16,052 units in Canada

Heater And Defroster

Issue: On certain vehicles, a software problem could cause the heating, ventilation and air conditioning (HVAC) system to enter a failsafe mode. As a result, the heater could stop working. If this happens, the windshield defroster may not work properly. Note: This problem could cause an "EV System Malfunction" or "Drive Start Control Malfunction" message to display. Safety Risk: A windshield defroster that doesn't work properly could cause reduced visibility and increase the risk of a crash. Corrective Actions: The company will notify owners by mail and advise you to take your vehicle to a dealership to update the HVAC system electronic control unit software. The dealer will also inspect and, if necessary, replace the electrical compressor.

UNKNOWN OR OTHER

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 — the maximum value the sensor can record) for approximately 1.75 seconds prior to impact. Brake hydraulic line pressure peaked at 12.144 MPa and remained above 7.8 MPa throughout that period. Throttle position was 0.0% for the entire recorded interval. All four wheel-speed sensors recorded 0.00 km/h for approximately 2.95 seconds prior to impact. Steering input was effectively neutral; no skid or loss of directional control occurred. The longitudinal accelerometer recorded a peak deceleration spike of -8.97 m/s² at the moment of impact — a value that requires forward velocity and is physically inconsistent with the wheel-speed data showing the vehicle stopped. The Pre-Collision System (PCS) main switch was ON throughout, with no faults, no obstruction flags, and no warning, pre-brake, brake-assist, or auto-brake activation recorded. The Parking Support Brake (PKSB) did not activate. No diagnostic trouble codes were set. In plain terms: with maximum brake pressure applied and zero throttle input, my vehicle continued to move forward into a clearly visible stationary obstacle. The brakes did not maintain authority over the powertrain's creep torque, and no advanced safety system intervened. This indicates a potential defect in the vehicle's brake-override / creep-suppression

UNKNOWN OR OTHER

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 operator of the commercial truck was unaware of the impact and safely continued driving forward without stopping. The vehicle's brakes entirely refused to re-engage until I frantically pumped the physical brake pedal and cycled/pressed vehicle control power switches. This action seemingly forced the electronic braking modules to reboot or re-establish hydraulic pressure, allowing the vehicle to finally come to a stop. The vehicle was subsequently removed from the active roadway. This is a severe, life-threatening safety defect involving a total loss of electronic brake-by-wire and friction braking application without any mechanical override intervention, presenting an extreme hazard. The vehicle has been towed directly to an authorized Toyota dealership for a comprehensive electronic diagnostic pre-scan of the Skid Control ECU, Electronic Parking Brake system, and 12-volt auxiliary power systems to retrieve the stored DTC fault logs and freeze-frame data.

WHEELS

Steering system, potentially related to electric power steering (EPS) or driver-assist systems (lane keeping or steering assist). While completing a routine right-hand turn, my husband began to straighten the steering wheel when the steering system suddenly and sharply turned further right without any driver input. This caused the vehicle to strike a curb, damaging both passenger-side wheels and the front tire. There were no warning lights or indicators, and road and weather conditions were normal. The uncommanded steering input appeared to come from the vehicle itself. The incident resulted in loss of directional control and could have been severe had another vehicle, pedestrian, or cyclist been present. This behavior reflects a serious and unexpected failure in the steering or driver-assist system, posing a direct threat to driver and public safety. I reported the incident to my local Toyota dealership. I have since signed Toyota’s EDR (Event Data Recorder) consent form, and an official inspection has occurred but they haven't provided detail. They also did not make me aware the inspection was taking place and did it without coordination. They have not confirmed that this has happened before. A similar, though less severe, issue occurred previously while I was driving on the highway. As I approached a merging lane to my right, the car suddenly pulled sharply to the right, seemingly misinterpreting the lane markings or misjudging its position. There were no vehicles next to me at the time, and I was able to regain control. While it did not result in a collision, it was alarming and appears to have been a driver-assist or steering control malfunction.

STRUCTURE:BODY

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 others at risk of running over a large number of components that were left in the road. I read many other instances of other people with the same vehicle (as well as with the Solterra) having an issue where the felt fender liners can become saturated with water, sag, and get caught in the wheels, ripping them off. I was one of those unlucky people to lose both sides and the splash guard all at the same time. The dealership / body shop inspected the vehicle. No warnings at all - just sudden ingestion of the fender liners into my drivetrain.

Houston, MD

VISIBILITY:DEFROSTER/DEFOGGER/HVAC SYSTEM:COMPRESSOR

What component or system failed or malfunctioned, and is it available for inspection upon request? The HVAC system, specifically the electric A/C compressor, has failed. The system produces a loud grinding/buzzing noise and has been diagnosed by authorized Toyota dealerships as requiring full compressor replacement. The vehicle is available for inspection upon request. How was your safety or the safety of others put at risk? This failure directly impacts the vehicle’s defrost system, which is critical for maintaining windshield visibility. Reduced or failed defrost capability creates a safety hazard by impairing visibility while driving, increasing the risk of an accident. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes. The issue has been confirmed by multiple authorized Toyota dealerships, including Sheehy Toyota and Mike Calvert Toyota. Both independently diagnosed a failed A/C compressor requiring replacement. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? Yes. The issue has been escalated to Toyota Corporate, and a case manager has reviewed the dealership findings. Documentation has been submitted to Toyota for warranty and goodwill consideration. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? Yes. A grinding/buzzing noise began when the A/C system was activated and was formally reported to Sheehy Toyota on October 27, 2025, while the vehicle was under warranty. The issue was not repaired at that time. The condition progressively worsened and resulted in confirmed compressor failure on March 25, 2026.

Gardena, CA

ELECTRICAL SYSTEM

The vehicle experienced repeated electrical and brake system malfunctions that pose serious safety concerns. On multiple occasions, the brake pedal became stiff and unresponsive while driving, and the parking brake system failed to engage properly. In addition, the ignition system often failed to start, even when the battery and all power indicators appeared normal. At times, the vehicle’s electrical system completely shut down without warning — causing loss of power functions, dashboard lights, and essential safety controls. These failures occur intermittently and unpredictably, making the vehicle unreliable and unsafe to operate. The issue has been reported to the dealer for inspection, but the problem continues to occur. It appears to be related to the vehicle’s electronic brake control and ignition system. This malfunction places the driver and others at potential risk, especially if the brake system or electrical components fail while the vehicle is in motion.

WHEELS

I am writing to formally report ongoing issues with my Toyota bZ4X that raise serious safety concerns. The vehicle has been inspected twice by authorized Toyota service centers, and each time I have been told that no problems were found. However, the following issues continue to persist:     1.    Inaccurate Battery Readings: The electric system appears to malfunction regularly. The displayed battery percentage and estimated mileage are inconsistent and unreliable. For example, the battery may indicate a higher percentage while simultaneously showing a drastically reduced range, or vice versa.     2.    Lane Departure Warning Malfunction: The lane departure system activates erratically, sometimes without any lane deviation. At other times, it fails to engage when it should, which compromises the vehicle’s safety features.     3.    Tire Pressure Monitoring System (TPMS) Alerts: Warning lights frequently come on indicating that the tires are losing pressure, even after verifying that tire pressures are within recommended levels. These warnings occur unpredictably and without cause. Despite having the vehicle inspected twice, I have not received a resolution or acknowledgment of any defects. Toyota has stated that nothing is wrong with the vehicle, but the issues are ongoing and continue to impact the car’s drivability and safety. These problems are not only frustrating but also present a potential risk while driving. I am requesting that Toyota take this matter seriously, investigate the root cause of these electrical system malfunctions, and provide a resolution that ensures the vehicle operates safely and reliably.

ELECTRICAL SYSTEM

The 12 volt battery does not maintain a charge. I have had it replaced twice. I purchased new January 2025; first battery replaced on March 20, 2025; second battery replaced August 13, 2025. I am currently having the same issue with the battery management system which controls temperature and battery usage. After sitting overnight, I drove my car approximately three miles parked and attempted to use the key fob to secure the vehicle, it failed. I had no problem or indication at the start of my trip. I had to secure the door with my physical key. I returned to the vehicle 15 minutes later and the key fob would not work at all. I accessed the vehicle with the physical key. The alarm was activated upon entry. I tried to use my key fob to get the vehicle to deactivate the alarm system but it would not work. Approximately five minutes later and after several attempts, the alarm stopped and the vehicle was showing ‘Ready’ but ‘No Key Detected’ was flashing on the information screen and vehicle would not change mode from park to reverse or drive. After several attempts of holding the key fob directly over the ‘START/STOP’ button, the car showed ‘ READY’ and I was able to change modes. The vehicle started flashing ‘NO KEY DETECTED’ continuously while I quickly drove back home. I parked in my driveway and made an appointment with Toyota for service. Later in the day, I attempted my key fob again, to no avail. I was able to get the key detected, display showed ‘Ready’ and mode changed. My car does not start (READY) until after several attempts. The dealership advised the battery failed a load test overnight and was replaced (August 15th) After the second replacement my car sat overnight. I drove a few miles to a charging station. I placed the car in ‘My Room Mode’ to have access to the climate control system and radio. The car started flashing ‘low voltage/battery’, I turned off the accessory mode, returned to the dealer, and awaiting resolution. Case filed with NCDS/CDSP.
