2024 Toyota bZ4X owner complaints

I leased a Toyota bz4x the parking brake lights and other lights come on and off while I am driving and fob is not touched. I took car in to be service for regular maintenance and was told I had to pay $295 and I am under warranty. I was sold the car brand new and I don't think it is. I keep hearing people talking when the car is powered off. I reported this several times and was ignored. My car keeps trying to cut off while I am driving and the car starts shaking, all the lights come on then go off. I was told I could get my car service anywhere for no charge under warranty. I was turned away. Its n been a year and no service car has not been serviced at all. I took it 2 times for service and the car has not been service. It is supposed to be new.

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 contr

On two occasions in the last month, when attempting to start the car, it doesn’t start, the interior dash lights start flickering, and a notification displays stating, “Parking brake cannot be applied”. I then have to “jump” the 12-volt battery. The main issue is the notification stating the parking brake cannot be applied because before shutting off the car the night before, I make sure the parking brake IS applied. However, it seems like the 12-volt battery is dead when I attempt to start it the following day; it automatically turns off the parking brake or at least notifies me that it is in error based on the message I receive.

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 compromis

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 w

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 witho

The air conditioner/heat pump has went out twice in 5 months. AC compressor failure poses several safety risks, including the potential for fires, refrigerant leaks leading to health hazards, and increased humidity fostering mold and mildew growth, which can worsen indoor air quality and lead to respiratory issues. Causing concern of leaking refrigerant into the cabin of the vehicle could lead to cancer and death.

Few days ago I was driving in the rain . suddenly i heard a scratching noise > i stopped the vehicle and looked underneath i saw a plastic sheet hanging . this happened while driving on the flash of water and due to impact of water because toyota used a very cheap quality sheet underneath for protection with plastic bolts . i took the vehicle to the dealer ship and they refuse to fix it under warranty stating that it happened due to impact which is not covered. the cost is $550 to fix it. this all happened due to cheap quality plastic sheet and not my fault . toyota should cover it under warranty.

Left front fender and hood contacted upon going into a dip in the road durning road contruction performed by bituminous roadways, inc. Damage to fender and hood. Vehicle body and or frame wisted.

On [XXX], while driving through a common roadway puddle at a safe speed, the front bumper on my BZ4X detached from the undercarriage shield and tore away from the clips. This type of damage is clearly disproportionate to the conditions and reflects a deficiency in structural design. After researching this issue, I found that many other BZ4X owners have experienced the same bumper detachment and undercarriage shield failure under minimal driving conditions. These consistent reports indicate a widespread manufacturing defect, not isolated driver error or negligence. For example: On multiple owner forums and complaint sites like NHTSA.gov and Reddit, BZ4X owners have documented similar instances of bumpers tearing off from puddles or light snow.

I was driving very slowly (5 to 10 MPH) through a rain storm on May 28th. The water rose to about 6 inches (fairly still, not rushing water), and I heard a loud and alarming noise under the car. I drove on for one block on a neighborhood street until I could get to higher ground. I discovered that the force of the water pulled down the fabric and plastic shrouds from the wheel-well into the wheels. The cloth and plastic shrouds were then pulled under the wheels, and the whole connected assembly was ripped off the car. This caused damage to both front fenders, the front bumper, and possibly to the safety sensors behind the bumper. I took it to my local Toyota dealer the next day, and they said this happens all the time, and that it will cost at least $2,000 to repair -- maybe double

I am very concerned about potential accidents for my self and others driving this vehicle. I have multiple close call accidents because the left view mirror does't have proper view to see cars on left side especially if they are close. The way seat and the side of the vehicle is shaped its very hard to still see manually with head turned to the left rear side. The mirror or the shape or position needs to be changed for safety to prevent accidents.

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 hydraul

Driver sustained severe hand injuries due to airbag deployment while the hand was on the horn pad. Possible over-aggressive deployment or module failure. Incident occurred on [XXX], while driving a 2024 Toyota BZ4X (VIN: [XXX] ). Requesting formal investigation into the airbag system and front structural integrity of this vehicle model.

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-

The contact owns a 2024 Toyota BZ4X. When pressing the accelerator toelerator pedal to go onto the freeway, the vehicle failed to accelerate and suddenly shifted to neutral. The contact would have to press the brake pedal, the contact would immediately shift the vehicle back to Drive and continue forward. While continuing to drive, the vehicle accelerated. 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 battery failure, then recommended the vehicle be taken to the dealer. The vehicle was towed to the

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 conf
