NHTSA Complaint #11580515 — 2021 TOYOTA redundant SIENNA

In the 2-1/2 years than I have owned and driven this vehicle, I've had no problems. On Saturday, [XXX], driving home from a 80 mile trip, as I deaccelerated to make a left turn onto my street (speed was 7mph) I tapped the break pedal and the vehicle went bonkers! The Sienna veered right at a high rate of speed that the front end cleared the curb; the back end smashed into the curb flattening both rear tires and damaging the metal hubcaps; the vehicle speed tore off the bumper and both rear panels. I was able to steer the vehicle: missing a large 2-foot high tree stump; two other large trees; a 10-foot high solid fence at the yard back. I then drove down the sidewalk to the next intersection and was finally able to slow down. This entire time, my foot was on the break, but the vehicle would not stop. The Sienna is now at Faulkners Collision Center in Mechanicsburg with virtually no front end damage but colossal rear damage. The vehicle had 5-full maintenance checks since purchase. I was not told of any suspected problems and never received a vehicle recall. I could have been killed or may have killed others as there is a playground on the corner of this block.
