On July 24th, I experienced sudden unexpected acceleration with my 2021 Toyota Rav4 Prime XSE (41,600 miles) while driving in the electric mode. I was lining myself up to reverse into my garage and as I paused to switch gears to reverse, the car suddenly accelerated full-speed towards my neighbor's house. I slammed the brakes but that had little effect. The car slammed into the house, through the garage door and my car was only stopped when hitting an SUV parked in the garage, pushing it forward about 2 feet. No air bags were deployed, the collision detection system on the vehicle did not seem to work and tire marks from my braking were visible from the middle of the road. I have found a number of very similar incidents with Toyota cars described online. Cars were often turning into parking spaces at slow speeds and ended up accelerating into lamp posts or buildings. If there hadn't been a car parked in the garage, I can't imagine what might have happened as the car was probably going 35 mph+ upon impact. There were no warning lights and the collision shop informed me that there were no diagnostic codes when they downloaded the computer.

During snowy but manageable conditions, the brake system on my 2021 RAV4 Prime SE failed to respond, and the vehicle did not decelerate when I pressed the brake pedal. A “Pre-Collision System Malfunction” warning appeared shortly before impact. I was unable to steer away despite attempting an evasive turn. The vehicle collided with the car in front of me, and the airbags did not deploy. I was driving at a reduced speed due to snow. The vehicle ahead (a BMW SUV) began slowing. When I applied the brakes, my RAV4 Prime did not slow down at all—there was no deceleration, no ABS pulsing, and no traction control intervention. The vehicle continued moving forward as if the brakes were not engaging. At the same time, I saw a dashboard warning indicating a Pre-Collision System (PCS) malfunction. I attempted to turn the wheel to avoid the collision, but the vehicle did not respond to steering input quickly enough to prevent impact. Despite the collision, no airbags deployed. The vehicle has been regularly maintained (oil changes every 5,000 miles, new tires last year, all service intervals followed), and there were no warning lights or issues beforehand. Safety Concerns: •Complete or partial brake failure •Electronic braking or stability control malfunction •Pre-Collision System malfunction •Airbag non-deployment in a front impact •Potential systemic issue affecting Toyota hybrid/Prime models This incident caused significant fear and distress for both me and my child who was in the vehicle, and raises serious concerns about whether similar failures could occur for other owners.

When engaged, this system cannot tell the difference between traffic lanes/markings and groves on the road/lines separating different coasts of asphalt and will try to steer the vehicle following those lines. It constantly tries to drive the car into the medians

My 2021 Toyota RAV4 Prime had traction control, braking issues and failure to warn in the event of a possible forward collision. On a few occasions the brakes seem to just slide and the car would keep moving. Last week I was in an accident and the emergency braking system, the forward collision warning system and all the air bags failed. The California Highway Patrol was surprised that even though the estimation collision speed was 60 mph the air bags did not deploy. I would have not had a chance to test out the air bags, emergency braking system or the forward collision warning prior to the accident.
