This Problem Across All Years
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.

Upon entering a light controlled intersection at a relatively slow speed (probably less than 20 mph} on wet pavement, an oncoming car suddenly made a left turn directly in front of me. I applied the applied the breaks hard and slid into the passenger side of the turning vehicle. The ABS system did not function. The air bag did not deploy. At the moment of the collision my speed was reduced and I do not know the threshold for airbags to deploy, but this was a direct front end collision. I was able to brace myself and was not injured. I am not claiming the airbag malfunctioned as the speed at the moment of impact was not high. However, I have complained to the Toyota dealer service department almost since the car was new, that the ABS does not function. They have repeatedly told me that it is fully operational based only on the fact that the system registers as "on." Being "on" does not mean it is functioning. Questions: What component failed? ABS and possibly airbag How was my safety at risk? Non functioning ABS resulting in a potentially preventable accident Has the problem been confirmed? Yes, byt the dealer though they claim the sliding of the car is due to old tires. However, the tires are withing the legal limist for tread depth and I have complained about the problem since the car and the tires were nearly new. Has the vehicle been inspected? yes, byt the Toyota dealer and an independent Toyota crash inspector Were there any warning lights etc? No

MY [XXX] ’S) SUDDEN ACCELERATION INCIDENT [XXX] - TOYOTA RAV4 2021: I was gliding into a parking space with my foot on the brake and as I went to straighten out the wheel to come to a full stop the car lurched forward full speed and smashed into the car parked in the row that was facing me. Good thing there was no one in that car, it had been backed in so I hit the rear end of it. The damage is so extensive it is beyond comprehension. My airbags did not deploy, which they should have. I saw that the ‘malfunction brake’ orange light was illuminated as I went crashing into the parked car and could not believe that the automatic anti-collision brake system failed - it was as if the car was possessed and the scariest thing ever. Towed to the dealer I bought it from. I have now read all of these other incidents that are the same as mine and this is no joke. We all could have been killed and there are people that most likely have been that have never been reported. I have been driving for over 40 years and have never experienced anything like it. Computers and software have glitches all the time, and if Toyota does not do something about this that means they do not care if their customers die. That makes them murderers. I loved my RAV4 more than anything, it is an eplugin hybrid and the best! I would/will never drive that car again, ever, and I am going to see to it that Toyota Corp, who is liable, reimburses me every penny I spent on that car, plus any legal fees and hourly wages for how much time I now have to spend on dealing with this whole thing, one of which is having to prove to my insurance company that this was NOT my fault so my rates do not go up! The dealer paid off my lease and never made me come pick up the car as I never had it fixed. Of course my insurance went up as they had to pay the damage to the other car! I now have filed a small claim with my local court to recoup the money for increase in insurance, deposit for Rav4 INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT

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.

My RAV4 PRIME was in stop and go traffic. Brakes did not switch from regen braking to physical brakes. Slammed on the brakes several times, they did not slow the car enough. Eventually the brakes locked up as the RAV4 rear ended the car in front. Pushing that car into the one in front of it, and that one in front of that, and that one in front of that. Causing damage to three other cars. Two other people are claiming medical, the driver went to the ER. Air bags did not deploy. Taking to the repair shop. They were shocked that the air bags didn't go off given the the condition of the frame. Toyota Motor North America (TMNA) did an inspection to read the event data recorder (EDR). Brake were applied at -1.5 seconds before impact. And here is the weird part, saying that the ABS activated then too. There was no notification, and the brakes locked up. Speed went from 46 to 21.1 mph. This occurred at 3,573 miles on only a few month old RAV4. I'm well aware of what ABS feels like when it goes off.
