I experienced a sudden vehicle acceleration event on April 6th. I followed Toyota's investigation procedure and even met with a technical expert and we agree on the following points: The event would have shown up as two separate events in the ABS history queue. An initial vsc event (sudden acceleration) closely followed by the ABS event (my pressing on the brake pedal harder in response to the sudden acceleration) if a check of the ABS history queue would have been done immediately, both events would still have been stored in the ABS history queue. The small capacity of the ABS history queue, coupled with the recording of many frequent traction control (trac) events pushed the record of my ABS- and vsc events out of the ABS history queue. The ABS system should not engage when the vehicle is stopped or moving slowly as in my incident. So, there was a malfunction of the control system that remains unresolved. Toyota refuses to acknowledge the existence of the problem. Because the ABS system should not have engaged when the vehicle was either stopped or moving slowly, there is absolutely clear evidence that there is something wrong with my vehicle. I think Toyota is engaged in a cover-up regarding the sudden acceleration problem. I request that the us federal government order Toyota to do the following since they refuse to do it voluntarily or at my request: Include an immediate examination of the ABS history queue in the health check. Create, and install in my Rav4, a new version of electronic control software that implements the following changes: A.separate queues for each for each of the three types of ABS history events: ABS, trac, and vsc B.increased ABS history queue capacity to ensure that 90 days of each of the three types of events are stored. C.all ABS history events are time-stamped and date-stamped.
