I was driving along with no traffic in front of me and no oncoming traffic when the automatic braking system engaged with no vehicles in front of me, this was at 7:42 am on Monday August 12, 2024. This was not the first time it had done this, but the first time I had the time and no traffic anywhere around to confuse the system. My concern is that if another car was following too closely they would have hit me since there was no reason for the emergency breaking system to engage.
The driver was driving into a parking lot preparing to park, when the vehicle accelerated and started going forward at a higher speed. The vehicle struck a parked vehicle, then travelled across the parking lot, over curbs, a grass median, landscaping, and struck a rock building at a high rate of speed, causing a partial collapse of the wall. The vehicle is available for inspection through the insurance company. No analysis of data was done and nothing was inspected. There were no symptoms of the problem beforehand. The vehicle has automatic emergency braking, but it evidently didn't operate. It is unknown if this was caused by driver error in accelerating and never braking.
