NHTSA Complaint #11464100 — 2021 TOYOTA RAV4 PRIME

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.
