Tesla's full self-driving software continues to malfunction. On January 30th at 9:50 a.m. mountain standard Time I was parked at work and discovered my vehicle was left unlocked with a partial window unrolled. This was my first indicator of many faulty problems signaling the vehicle was not operating properly. The vehicle has a proximity sensor via Bluetooth that locks and unlocks the vehicle on the owners approach was not properly working. On January 31st I experience a catastrophic failure with the software of the vehicle as I was locked out of my vehicle after utilizing summons feature that stopped the vehicle in the middle of the intersection obstructing traffic. Police arrived on scene within 30 minutes and we were unable to put the car in any gear to either drive the vehicle or place it in neutral to roll it out of the way. I have detailed video of the incident which is a better accounting of the incident on both occasions, the 30th and 31st of January. This is roughly the third or fourth occasion of Tesla's system producing a catastrophic failure resulting in damage to the vehicle or property damage.
