Assist problems of the 2020 Tesla Model Y

I have Tesla’s fsd software that consistently tries to enter closed highway ramps where the flags, lights and barriers are clearly marked as “do not enter”. I have reported this to Tesla a dozen times with no improvement or response. I’m sure there will be retaliation for this but I am sick and tired of swerving to avoid a fatal collision. Too many other safety issues with fsd to document.

Chatgpt subject: safety concerns regarding recent Tesla autopilot changes (campaign #23v-838) dear NHTSA, I am writing to express my concerns regarding the recent required changes to Tesla's autopilot system under campaign #23v-838. While I understand the importance of updates for safety, it appears that these modifications have had an adverse impact on the vehicle's safety and increased the potential dangers of driving. I urge the NHTSA to thoroughly investigate and address these issues to ensure the continued safety of Tesla vehicles on the road. Your prompt attention to this matter is crucial for the well-being of Tesla drivers and the public at large.

On a round trip from albuquerque, nm to tucson, az, we experienced 8-10 instances of phantom braking in our 2020 Tesla long-range Model Y. The occurrences happened when the car was in adaptive cruise control and lane keeping assistance. Highway speed was typically 75 mph, weather was sunny, and roads were clear. Overall, an unnerving experience!.

Prior to the incident a message appeared in the car indicating that the lane departure avoidance features unavailable - features may be restored on next drive. Tacc was activated on the car. Auto steer was not activated. The car is equipped with autopilot only. It was traveling in the furthest left lane. A truck in the center lane attempted to merge into the left lane where our Tesla Model Y was traveling. The car then steered hard left causing the car to be nearly our of control and swerving left and right. We were able to get the car under control, but we nearly were run off the road.

On 9/11/22 at approximately 1:30pm I was driving north on i65 in northern tennessee just before the kentucky border. Conditions were heavy rain. Traffic was moving but heavy. I had autopilot engaged. I was traveling approximately 70 mph. Three lanes of traffic. I was in the far left lane. I had my hands on the steering wheel. Without any prior notice, I lost total control of the car. Seemingly all four wheels were autoplaning due to the wet pavement. I had zero control of the car. The car seemed to slow down, drifted into the full shoulder left lane, then rotated 90 degrees counterclockwise and hit the concrete center median. The car then rotated another 90 degrees counterclockwise and came to a full stop all in the left shoulder lane. The front airbags deployed. There were three people in the car. We were not injured and left the vehicle on our own. Miraculously no other vehicles hit our vehicle.

On open freeway, I 76 between 7 am and 8 am Tuesday November 16, between ogdallala ne and brush CO. Using adaptive cruise control with autopilot steering (as well as without autosteer), multiple episodes of severe "phantom breaking" where the car slams on the breaks for no apparent reason. No other cars around. Flat, clear open freeway. Reported the issue to Tesla service. Even though there were multiple (>10 episodes in one hour) they have demanded to know the exact time stamp. I was able to give time within 1 hour period, vehicle location. Service says if there is a hardware issue they will look at it. If it is "firmware" it will need to wait for a firm ware update. This is dangerous. What if the car slams on the breaks at 80mph, with someone following close behind? you might be rearended. Really serious safety issue. My car has latest fsd beta 10. 4. This is much worse than before this "upgrade".

I installed the full self-driving beta on my Tesla Model Y the morning of 10/24/2021. Immediately after the update installed I began experiencing issues with the autopilot and tacc systems, as well as spurious forward collision warnings. These warnings involved the standard warning beeps and red indicators on the driving display, and at one point included an unnecessary emergency braking incident when no obstacle was in front of me. As such, I had reverted to driving the car in manual mode, not on autopilot, but left the option to use the autopilot systems and associated safety features enabled. I was driving in full manual mode on an interstate in the left lane approaching a tunnel, with no vehicles or obstacles in front of me. The car indicated a forward collision warning with the loud beeps, and the car applied brakes and started to swerve into the lane immediately to my right, in which another vehicle was driving and had to swerve as well. The car detected the event and saved the camera footage to my installed ssd. I have reported the incident to Tesla, including providing the video of the incident. I am awaiting response from Tesla.

We experienced multiple (4-5) "phantom" braking events while driving cross-country using adaptive cruise control & lane keeping assistance on open interstate highways during the summer of 2021. There were no vehicles or other obstacles in our driving lane ahead. Sometimes it seemed like it happened when we approached a shady underpass. Other times we couldn't see anything that might have confused the adaptive cruise control. We did not have full autopilot engaged during any of these times, only adaptive cruise control and lane keeping assistance.

The other day I was stopped at a red light, awaiting green in a left turn only lane. It was a long light and I may have been distracted by a conversation with my passenger. I am 99% certain that I did not have my foot on the brake pedal because I rarely use it now-a-days with regenerative braking and tacc. The green light chimed and I instinctively pushed upward on the right stalk, double checking (in my mind) that I had disabled tacc and autopilot, knowing that I was about to turn left. Unfortunately this 'conditioned' behavior of mine inadvertently put the car in reverse!! I pressed the accelerator and nearly backed into the car behind me. It completely caught me off guard since my expectation was that the car would move forward. Obviously I was wrong. The driver behind me was disturbed, however I did avoid making contact by hitting the brake pedal. While I certainly realize that I am fully responsible for the confusion, I do believe that Tesla safety engineers might want to explore this scenario and seek out a preventive safe-guard. Perhaps software can prevent car from switching to reverse unless the brake pedal is depressed. Or maybe a much larger "r" indicator that blinks and beeps. I'm sure it is an easy fix.

~3 times the car slowed down at ~65mph while on cruise control. Thank goodness no one was closely following us!!! dangerous!!! the car lane assist feature which should warn when us when we're veering to closely to another lane or the edge of the freeway only works intermittently.
