While slowing to turn into a turn lane, my care unexpectedly accelerated to a very high speed, causing me to crash straight into a signal light post. The light post was knocked over by the force of impact. The car ended up around the corner, facing the opposite direction and having hit another car. Police responded to the scene and inspected the vehicle, which was towed away. An insurance claim has been filed, though I am unaware if they have inspected the vehicle yet. The passenger airbag deployed but driver airbag did not. I had no warning before the sudden acceleration and this is the only time something like this happened.
