   On Tuesday, [XXX], around [XXX] returning home and in my driveway when the following happened. Pulling into the left side of the driveway because a utility van was parked on the right side of the driveway with the rear door and driver’s side door opened with no one in the vicinity. There was not enough room to go forward into the garage. I was almost at a complete stop with the intention of getting out of the car to shut the drivers side door. That was when the car sped up…

   On drives longer than 40 miles, camera faults cause cruise control systems to degrade in function and then when the faults are cleared, full functionality resumes without driver alerts. Side repeater camera feeds and rear camera feeds inconsistently load, or take an extended time period to load (10+ seconds). Tesla has confirmed that the autopilot computer (HW3) likely needs to be replaced, but this error/messaging is not directly accessible to the customer. The inconsistent…

   I own a 2020 Tesla Y with Hardware version 3 and after a few weeks of a free trial, purchased Tesla's Full Self-Driving Software (FSD) version 12.3.6.

   While driving in cruise control mode, not auto steer, and with no vehicle in or obvious obstruction in front, the brakes will be applied without warning (phantom braking). It has happened multiple time in the years of ownership. It has happened once or twice with a vehicle following resulting in near rear-end collision. In one case this resulted in the follower reacting with "road rage," passing with horns blaring and braking in front of my vehicle. I have this recent…

   While driving at highway speeds (50mph-80mph), on 2 lane or 4 lane highways, in the day or night, in sunny conditions and overcast sky's, while using the cruise control (auto-pilot), the car will suddenly and unexpectedly apply the brakes. It happens between 8 and 10 times on every road trip, each way. Not only is it a shock to me as there is never a visual obstacle that seems to be causing the hard braking, but it is a dangerous safety issue to other motorists too. This has…

   During phone calls, the system would start making sparking noises and stall the calls. While navigation was input parts of the screen would disappear. While backing up, the rear cameras would freeze and stall. The rear camera freezing had caused us to get into an accident, and caused us to have 4 near misses. When I was trying to download the latest software release, the software download froze and never downloaded. I started to drive to the Tesla dealership and as I was…

    • Cruise control braked hard unexpectedly and for no reason. I'm describing a specific instance here, but this happens regularly. Specifically, the traffic aware system frequently misinterprets the data it is collecting. In this case, a car in an exit lane, slowing down to take a ramp. I was not in that lane, but there was no painted line between my lane and the exit lane. My car slowed to match the speed of the car on the exit ramp. In other cases, my car has slowed…

    While driving on the highway at 59 mph using Tesla Autopilot functionality the vehicle braked so hard the wheels locked up and skidded without warning. There was no vehicle directly in front but there were two semi trucks on either side and vehicle directly behind me. The vehicle behind had to brake hard not to run into me. I took control of the vehicle and pressed the accelerator to regain speed and avoid an collision.
