Critical safety concern regarding the braking system in my Toyota Rav4, 2021 which I believe may warrant further investigation for a potential recall as there are none at this time. The issue pertains to the breaking system, which locks up unexpectadly during use, casuing sudden and severe break locking without warning (unable to break). I suspect as many others online who have mentioned this issue on Toyota Forums is that it is the prime breaking software. I have had my breaks inspected multiple times as I was in a car accident where the breaks did not work and I rolled into the car in front of me when we were starting to proceed through a green light at 5MPH. When pushing on the brakes nothing happened and I rolled into a mother and children. Luckily I did not cause significant damage however I explained to her my breaks would not work. This accident then caused me to be dropped from my insurance (policy termination by Geico) since I had switched providers and happened during my 30 day grace period. This malfunction created a significant safety hazard for myself and others on the road as well as fear that it will happen again and should be investigated as I have have this happen multiple times since the accident.
