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 p…

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.

I submitted this form earlier, but I’m unsure whether it went through. If this is a duplicate, please disregard. An incident of sudden, unintended acceleration occurred while pulling into a gravel parking area on a hillside at dusk. While turning, the vehicle suddenly lunged forward and struck a tree stump. It would have been avoided without the sudden acceleration. The driver slammed on the brakes, and the vehicle came to rest right at the edge of a downward slope.

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 c…

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.

These consistent reports indicate a widespread manufacturing defect, not isolated driver …

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…

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.

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 c…
