While driving at a normal speed and turning around at an intersection in our neighborhood, the car suddenly went out of control, causing the car to hit a fire hydrant in front of a home, smashed a tree before crashing into the siding of the home. Insurance deemed the car as "totaled". We were reimbursed by insurance so this is not about monetary losses, but a report to protect other drivers and their families. The Tesla database records mentioned user acceleration and error, but this doesn't sound like a reasonable cause. The airbags didn't open and neither did the automatic emergency braking or forward collision warning work. I was unable to brake and control the car to stop. This accident is captured in the security system video of the impacted home.
