1 Warning problem

Failure Date: 02/22/2022

While using wildly falsely marketed $10k "full self driving" add-on across multiple software revisions and after reporting each and every bug to company I have experienced potentially fatal phantom breaking while at highway speeds and could have been killed by rear ending on at least 4 occasions. Have experienced 20+ erroneous forward collision errors with automatic breaking or lane assist corrections for obstacles such as hills, mailboxes, trees, absolutely nothing at all, etc. When driving around mildly banking left turn corners with 45mph speed limits whenever approaching a left turn lane within median the car will violently lurch into the turn lane causing panic for passengers and nearly causing a collision within resuming concrete median. While using autopilot the car failed to stop, correct or warn when a vehicle entered my lane and caused an accident with several thousand in damages. Car does not properly break for turns on highways requesting driver take over for what should be an easily navigable turn. Doesn't take apex or break early and will drift lanes making other surrounding drivers nervous. Moving the horn from muscle memory location to awkwardly placed touch button has prevented timely use of horn on multiple occasions which could easily result in fatal accidents. Overall this car is a literal death trap not at all even remotely ready for production use on public roads and neither I nor any of my passengers feel safe using the feature that was over priced, over promised and under-delivered. Tesla service center employees too worried about retaliation from management to inquirer about problems because of previous reparations from corporate offices. List of problems is shockingly egregious and should not be legally permitted on roads.

2 Warning problem

Failure Date: 12/14/2021

Autopilot cut off while driving on curved highway exit ramp, leading to driver's side of car grazing guard rail and rims of wheels grazing curb. Mostly paint damage. Repair estimate: $7,000. 00 car sustained minor damage, but I was told by collision center that other similar incidents had occurred, including one in which car had gone off the road into a ditch. I have confirmed this is a consistent software problem, cutting off on all highway exit ramps. Problem reported to local Tesla service, and they uploaded data from the car remotely. There were three dings as an alert, and a warning appeared on driver's display "autopilot guidance complete" and beneath it, in very small letters difficult to read, "tap accelerator to continue. " I consider this a software design flaw. Default on a curve should be to switch from autopilot guidance to lane keeping, not shut off altogether. Also, warning should be more visually an audibly prominent. For example, when guidance is not available on a city street, there is a distinctive alarm and obvious flashing on dashboard display. There should be a similar warning when autopilot is about to shut off.

3 Warning problem

Failure Date: 07/27/2021

On at least nine occasions the car has very suddenly and with no input from driver braked hard during passing another vehicle, when assuming the original lane after passing a vehicle, and, on one occasion when no other vehicle was close by. I have brought all incidents to Tesla's attention. They tell me the problem resides in the software of the car and that they "are working on it". This is a very serious problem, which has been going on for over a year in my case. A totally unacceptable and extremely dangerous situation! occurred in December 21, 2020; several times during the summer of 2021, other sporadic times, and most recently on September 6 and 8, 2022.
