36 Electrical System problem

Failure Date: 08/08/2022

Tesla Model 3 main computer system failure. Failure was not cause by any negligence by the operator. The vehicle was parked over night and upon attempting to operate the vehicle the following day there was no power to the screen. There were no warnings prior. The screen which displays vehicle speed, vehicle battery level, seatbelt warning indicators was inaccessible. Also as a result of the computer failure the vehicle did not emit the required pedestrian safety sound, the front and rear collision warnings were disabled, charging was not possible, the ability to disable passenger airbags in case of a child needing to be transported in the front was inaccessible, if the vehicle was operated during winter the ability to defrost the windshield would be impossible and all safety and security features were disabled. The screen/computer has been an issue for several owners as easily viewed by a simple google search. The vehicle is only a year and a half old and was purchased new. The issues that occurred from the defective computer could of easily have caused of an accident or a caused disabled pedestrian to have been hit. The computer was deemed the cause by Tesla’s service professionals.

37 Electrical System problem

Failure Date: 07/06/2022

This "self driving" Model 3, with FL license plate pzyh35, attempted to merge onto i95 south from an on-ramp, and very nearly caused a major accident. The vehicle had a bumper sticker on the back that said something like "please be patient, I am a self driving vehicle. " the vehicle was merging from a left side on-ramp, at a very low speed, and crossed two lanes of interstate traffic, very erratically accelerating, then braking, then accelerating again, and then braking. My vehicle was directly in its path, and I had to brake hard, and take to the shoulder to avoid the collision. If this vehicle's trips are logged, it needs to be investigated. If it weren't for the humans paying attention, the actions of the Tesla car/driver would have caused a major accident, and most likely bodily injury or death.

Https://youtube. Com/channel/ucnkrwnr_lakd4nelwyabuga my youtube channel has 13 videos about Tesla safety concerns. They are the only videos on my channel. The minutes long clips show what happens when the mainframe screen goes black, dies out or powers down while driving. Listed from memory are the following concerns associated with the Tesla ‘black screen of death’: 1. No energy/distance shown 2. Glove box is inaccessible 3. Front trunk ‘frunk’ cannot be opened 4. Proof of signalling is gone 5. Proof of low vs high beam is gone 6. Changing of wiper speed is gone 7. Access to heating/air-con is gone 8. Back up camera is obsolete 9. Cameras used when signalling are missing 10. Speedometer is not visible 11. Odometer is missing (have never found it on screen when running anyways!) 12 air pressure indication is gone 13 gps is obsolete from memory that is all I have to add. Imagine everything that was/is available to the driver in every other cars dashboard and then take those parts away sporadically for minutes at a time and you’ll have an understanding of how precarious driving my Tesla can be. As an uber driver I had the opportunity to speak with a corporate agent who was my passenger. She said Tesla is aware of this issue. Having spoken with a Tesla rep at a Tesla garage I was given the same advice found on internet forums: “find a place to park, park, press the steering volume & station finder buttons for 10 seconds until display starts up” this very rarely works, and is impossible, even dangerous in many situations. I’ve learned to drive with this continually faltering equipment, and I know every Tesla driver I’ve spoken with must do the same to varying degrees. While all Tesla drivers experience this, none are as repetitive as mine and none seem as proactive to inform government agency of this. Next week, may 26, I have an appt with a Tesla garage that will look into this when I bring my car in. Please view my videos.

40 Electrical System problem

Failure Date: 04/28/2022

We were driving on the freeway at 69 mph and suddenly with no warning the center console main screen froze. All electronic functions of the car stopped and the car was stuck at 69 mph. Speedometer and turn signals did not work. We managed to get to the side of the road (mechanical brakes and steering were unaffected). The car could not be put in park so a manual reboot was not possible. The car rebooted itself (screen went black and then came back online) after about 10 minutes or so and then the car functioned normally.

43 Electrical System problem

Failure Date: 02/08/2022

Since the v11 user interface update, when you put the car into reverse, the rear camera sometimes does not show up, or often shows up only after a delay. Sometimes the delay is just a second or two, other times it is a minute or seems to hang forever. Today I was parked in front of my kid's school dropoff zone, and needed to back up after they got out to leave. When I went into reverse the cameras were just black and stayed that way. This was especially worrying in this scenario since small children could be walking behind me that I wouldn't be able to see without the camera. This was never a problem until the v11 user interface update, which also causes other safety problems, by burying important functions behind menus. For instance you now have to dig into a menu and reach all the way to the right side of the screen to operate the wipers, you have to dig into menus to operate basic climate control functions that used to be immediately available, etc.

44 Electrical System problem

Failure Date: 01/18/2022

I was driving north on wisconsin route 14 at about 60 mph in my Tesla Model 3 using the cruise control. . When a large transportation truck came from the opposite direction, my Tesla suddenly braked sharply. A Ford model f150 truck was following behind me and almost crashed into the back of my car. Fortunately the driver was alert and by sharply apply his brakes on driving into the ditch he avoided colliding with me. This could have been (and nearly was) a lethal accident. I would urge that you put a recall on a Tesla vehicles until this problem is corrected. I have contacted other Tesla owners and they have experienced similar problems. I contacted my local Tesla service station and they seemed unconcerned about the problem. I urge you to issue a recall before someone is seriously hurt or killed.

45 Electrical System problem

Failure Date: 12/17/2021

The automatic rear trunk closure button gets water inside wetting the electrical wiring. It has caused my trunk to randomly open at times and more importantly, can cause an electrical fire. This has put my safety, as well as any passengers at risk for injury and or death. I have not reproduced the issue because it has not rained, nor have I had the car washed. I have notified Tesla of this approximately a month ago and they continue to cancel & reschedule my appointment. There seems to be no urgency to investigate or fix the issue. The vehicle has not been inspected by anyone to date. There was no warning lamps or messages prior to the issue.

While driving with cruise and steering control, car will emergency brake like something is in front of the car. Many call it "phantom" braking. One time on a 2 lane highway the car braked hard for no reason, it happened on the way to vegas and a large group of bikers were behind us. Very scary at highway speeds. We let the bikers pass.

Periodically one headlight starts flashing and my front turn signal won’t work. This typically happens in the middle of driving so I’m at risk of getting home safely.

52 Electrical System problem

Failure Date: 06/20/2021

After parking and leaving the car, I realize later the dashboard did not shut down. The dashboard was still illuminated, and I was also able to hear the sound from a tuned fm radio. I re-open and closed both the driver and the passenger doors in an attempt to shutoff the dashboard. Since I did not get the expected result, I decided to get back into the car. I sat down in the driver chair to investigate the problem when the car was instantly activated and switched to a sudden and uncontrolled acceleration. It crashed into a facing wall after a run of about 30 feet.

57 Electrical System problem

Failure Date: 02/20/2021

Heat no longer works in the car's climate control. This apparently is tied to faulty humidity and temperature sensors that must work properly for the heating system to work, and Tesla service centers are aware of this yet are not proactively replacing them. This is a safety issue in cold climates since the windshield defrost no longer works, and the car is unsafe to drive overall in cold temperatures without functional heat. This issue appears to be restricted to the 2020/2021 Model 3/ys with the heat pump that require these sensors to function properly. Another symptom is the climate screen displays an error message of "climate keeper is unavailable due to a system fault. ".
