2022 Tesla Model S Speed Control & Cruise Problems

Incident Description: While driving through a parking lot at 20 mi/hr, my vehicle's AEB system activated in response to another vehicle approaching from a perpendicular direction. However, the system's response was dangerously delayed and inappropriate stopping the car right in front of the other car: The system failed to provide any advance warning or alert before applying the brakes The braking occurred too late to create adequate separation from the approaching vehicle The vehicle stopped directly in the path of the oncoming car, increasing rather than decreasing collision risk The abrupt stop left my vehicle in a position where I was at greater risk of being T-boned Only the other driver's quick reaction prevented a collision. Had that driver not stopped in time, the AEB system would have contributed to, rather than prevented, a serious accident.

Car without obstacle will without warning execute a hard slowdown/stop. We have received the latest OTA update and have disabled auto steering and fsd. These unplanned stops are incredibly dangerous when driving in traffic. They charged a substantial fee to enable FSD and we are afraid to use it which sucks but the fact that basic cruise control is so dangerous is criminal.

We took our first major road trip in our new 2022 Tesla Model S on Friday 10/14, leaving at 10:00 am for a 9 hour trip. During the trip the car experienced multiple severe incidents of the car braking hard while at highway speeds and two of the incidents almost caused an accident. The car drops 10 to 15 mph instantly for no reason. We drove the car home on Monday 10/17 without AEB, Auto Steer, FSD Beta, Emergency Lane Departure Avoidance and Obstacle-Aware Acceleration and used TACC occasionally and still had the issue but wasn't as severe. Even on the day we purchased the car (Sept 30) and drove it home (a short drive on highway 95) we had a similar incident but it was so new we weren't sure if it was us or the car but now we know it is a fault of the car and creates a very dangerous driving situation which could result in an accident or death to a passenger in our car or in the car behind us when our car decides to slam on the brakes for no apparent reason. There were no warning lamps, messages or symptoms of the problem prior to the failure. We turned in a service request to Tesla and their response was to drive the car and have it happen again and create a Bug report. So basically Tesla is asking us to put our lives on the line to help them diagnose the problem because they don't want to take the time to review the diagnostic data that is readily available to them. In our opinion, this is a very serious and dangerous problem and the car needs to be taken off the road until Tesla resolves the problem.

The car requires swiping the touchscreen to place it in drive or reverse. The touchscreen does not always register the intended change of direction, leading to unexpected, unsafe motion of the car. The area of the touchscreen that one must swipe is also often occluded by the steering yoke. This has happened multiple times, where the lack of strong enough feedback (or a mechanism that allows for less error-prone input) as to D vs R allows for an unsafe movement in the opposite direction of what was intended. In one case, there was traffic approaching, and the car ended up further in the path of that traffic. In another case The car should provide instantaneous tactile, visual, and/or audio output to clearly indicate that the car has shifted from D->R or R->D. A mechanical stalk or button, as was present in previous model years, would certainly be adequate.

While driving with Traffic Aware Cruise Control engaged and set at 55 MPH the car did a hard break to an almost complete stop in the middle of the lane for no apparent reason. This occurred at least two times and both times there was no traffic in front of me. The road was a two lane highway. There was oncoming traffic and cars behind me but no cars in front of me. The breaking was so hard on both occasions and it startled me and caused me to veer off the road in the first instance . The car behind me had to break suddenly as well. After the second occurrence I disengaged the TACC as it seemed to be sensing the oncoming traffic

I just completed a round trip from Minneapolis to Oregon. During cruise control, the vehicle frequently suddenly braked at highway speeds for no apparent reason. This was extremely dangerous a few times. I have put in a service request with Tesla.

PHANTOM BRAKING: I was driving northbound on the I-5 highway south of Sacramento, California using cruise control and traveling at the 70 MPH speed limit on September 14, 2022. At approximately 2:50 p.m., I moved from the right lane into the left lane by using the turn signal to execute the lane change. Once in the left lane, the car immediately began violently applying the brakes. There was a car behind me that appeared as if it was going to rear end me. I pressed on the accelerator pedal which allowed me to regain control over the vehicle and avoid being hit by the vehicle behind me. The weather was clear and visibility was excellent. There was no apparent reason for the emergency braking system to become operative.
