Warnings problems of the 2020 Tesla Model 3

Incident #1 vehicle sitting at a red light. After several seconds the vehicle operating under Tesla fsd suddenly started to drive as if the light had turned green, which it had not. I stopped it immediately. Incident #2 vehicle was stopped a t a red light and started forward again as it the light had changed but had not. I noticed a flashing red light at the next intersection a few hundred feet away. So, I went around the block and tried again and it behaved the same. After a few seconds it started to go again. There was not another light near where the first incident occurred.

Software update was pushed onto my car, after the update the car autopilot ecu no longer works. When the ecu finally failed these features were stuck or are completely broken/not working: - auto dim rear view mirrors (these were stuck in dim mode, preventing me from seeing in rain or darkened environments such as at night or under shade, 0% visibility under these conditions when changing lanes or reversing) - rear view camera completely stopped functioning, as did all cameras on the car - forward collision warning no longer works - autopilot (adas features in general) no longer functioning including lane keep assist - on screen navigation is locked in place where the car failed (screen shows location where the car ecu presumably failed). I am further unsure if the following features function as required: - airbag deployment - aeb (automatic emergency braking).

Vehicle must have thought a shadow line in the road from a bridge indicated a wall I was about to hit, as it slammed on the breaks in the middle of the freeway. Car behind had to swerve to avoid. On the same trip, several nags of 'keep eyes on the road' were incorrect, as my eyes were directly on the road, but phone was in hand functioning as a microphone taking voice memos. Car proceeded to shut itself down while in the middle of the freeway, causing me to go slower than traffic and put me in danger as cars behind me had to swerve or lane change to avoid me as I tried to pull off to the shoulder. These forced shutdowns from incorrect 'nag fails' are causing safety issues. Nag failures should not forcibly shut the car down. Not sure if this is being enforced by NHTSA, or why Tesla is choosing to disable their auto steer or fsd when drivers are detected to be failing nags - nags should be there to help drivers, and potentially the nag data/cab video can be used after the fact should a user failing nags be involved in an accident for insurance dispute resolution, but shutting the cars down themselves is causing issues.

Since the recall for autopilot / full self driving which required driver alerts (often called steering wheel nag), the alerts are now so frequent and reoccuring that it forces you to stare at the screen and not the road. If you look at the road, both hands on the steering wheel, every few seconds, as little as 10 seconds since the previous, the screen begins to flash (only at the top) indicating that you must now slightly shift your hands. These are often hard to see unless you stare at the screen and give no other noticable indicator. Recently I was just awarded a strike for not adjusting to it, about 30 seconds after the previous indication and it had no audible sound or indication the only warning apparently was a visual one. The screen is not in front of the driver like a heads up display, its off to the side. Other vehicles warn you not to use the on screen displays while driving, even Tesla, so why does this feature force you to stare at the screen your entire drive. It seems unsafe to force -constant- checks of the screen from the driver to determine if you're in autopilot compliance.

When driving in "autopilot" mode which uses adaptive speed control, the car suddenly slows down without any warnings. This happens even when there is no vehicle in front of the car and therefore slowing down is not expected. This has happened several times while driving on freeways. If it weren't for my immediate reaction, serious multiple-car accidents would have happened. My reaction has been to quickly disengage the "autopilot" system and manually accelerating to avoid rear collisions. The other issue is the car suddenly steer the wheel and drag the car to the side even when there is no reason to do so. In such cases, I have to forcefully steer the wheel to the opposite direction to avoid collision with other cars moving on either side, or parked cars on the streets.

Phantom braking issue. Cruise control set at 68mph. Medium freeway traffic at 7pm. Noticed disabled car ahead on the shoulder. No danger. As we approached the car, my car went into a panic stop as if it thought a collision was ahead. Car braked and skidded. I was able to regain control and accelerate and avoid a rear end collision. No waring or repair issues.

The other driver hit the rear of my Tesla Model 3 which cause the car accelerate fast about 40-50 miles, the brake is not working either. I can not brake or slow down the car.

The forward collision warning censor gives an absurd number of false positives. I have Tesla insurance, and the insurance rate is heavily affected by forward collision warnings. Nearly every day, one is triggered with -nothing- in front of me. I mean empty road ahead. Or, a car is about 7 car lengths ahead of me, they begin to slow down to make a turn, begin their turn, and nearly exit the lane. Without slowing down, and still 3 car lengths ahead, I get an angry forward collision warning and a major increase in insurance with -zero- risk of accident. It seems to happen most frequently at low speeds.

We were pulling our car from 5th floor of a parking garage and as the car was coming down the ramp into the 4th floor, it accelerated itself to a high speed, hit another parked car, and came to a stop hitting concrete pillar in the garage. Our car was damaged severely and all the airbags got deployed, smoke came out it. We are still in shock from the incident and it was a traumatic experience for all 4 members of our family including two of our children. It would have been catastrophic had there been another person around or if something more had happened. Our car unexpectedly accelerated and none of the warnings worked. Tesla car usually gives us warning (a shrilling beeping noise) when an unexpected obstacle, be it another car or a trash can or a human, is within a short distance of the vehicle. This warning sound comes up even when no automatic driving feature is used. But on that day, the warning sound did not come and we think the vehicle may have malfunctioned. When we searched in the internet, we found many incidents of unexpected acceleration with Tesla Model 3. When we brought our concern to the insurance, we were asked to report to NHTSA. The car is now with insurance and the manufacturer has not looked into it as we haven’t informed them yet. The car was in excellent condition and there were no warning or failure lamps on before the incident. This warrants your attention and hence we are writing this to you. Please advise us the next steps and if we need to preserve the car to retrieve any data recorded in the vehicle. For the safety of other drivers and pedestrians, this needs to be thoroughly investigated. Kindly do the needful.

Car decides to apply brakes for no reason.

Vehicle approached an upward slope which triggered a forward collision warning and (unsafe) emergency braking.

Driving on autopilot on a city street at 35 mph speed limit, while passing next to a ups truck parked on the right side of the street at the curb, but slightly protruding outside the parking lane, due to its size, my car sideswiped the parked ups truck, causing scratches on my car and totally obliterating my passenger side mirror. My vehicle did not stop or try to veer away from the parked ups truck, causing at a minimum $700 damage to my vehicle.

From the moment I drove my brand new Tesla off the lot - the screen - the only way to control anything about the vehicle - would freeze; black out; and take several minutes to reset itself. While in this completely inoperative state: the audio system would emit a high pitch noise; any ability to tell speed; turning signal status; anything was completely impaired; the climate control blasts on high fan a torrent of cold air. At 2000 miles; this has happened several hundred times - on average once every 10 miles driven; though sometimes twice within a few moments (boots up only to reset again) and sometimes it can go as far as 30 minutes without freeze; black; reset. This is easily the most expensive car I've ever purchased; and had nearly 0 miles upon pickup - it is easily the most frustrating experience I've had with a car. To not be in control or have any visibility to the machine driving at highway speeds when everything goes completely black and the computer takes minutes to reset. The repair facility has estimated $2400 which they're attempting to charge me.
