| Feb 2022 | UNKNOWN OR OTHER | The new Tesla touch screen UI is a major safe risk. Tesla has decided to hide the controls for the defrosters and wipers to such a degree that we are required to trust the automatic solutions for both and they both are abject failures. The manual controls worked fine, but the new UI is such a disaster, that we can no longer safely use the controls without taking our eyes off the road and touch the screen multiple times. I have contacted Tesla multiple times about this and will continue to do so requesting a way to roll back the software update. They refuse to do anything about this, so I have no recourse except to file safety complains to the NHTSA. | Crash: No Fire: No | Unknown |
| Feb 2022 | FORWARD COLLISION AVOIDANCE | With Autopilot/adaptive cruise control engaged, the vehicle slows precipitously on the freeways before large overhead signs across the freeway. There is no need for this reduction in speed due to safety. The system phantom brakes. | Crash: No Fire: No | Unknown |
| Feb 2022 | SERVICE BRAKES,FORWARD COLLISION AVOIDANCE | - Yes - The cruise control portion of autopilot has some dangerous bugs in it ('21 Model 3 Long Range). At freeway speeds, the phantom braking is scary ASF!!! Potentially, getting someone killed. While on my road trip between Los Angeles and Denver then back. I experience at least 20 to 30 phantom braking events from mild to dam near scaring the f$$k out of me. Most of these events were during the day at speeds that would have caused a serious accident if someone was following me too close!! During the night time the events were all mild in comparison to the day time events. -Yes -No -No | Crash: No Fire: No | Unknown |
| Feb 2022 | VEHICLE SPEED CONTROL,UNKNOWN OR OTHER,FORWARD COLLISION AVOIDANCE | Phantom breaking. The basic autopilot cruise control frequently + aggressively brake as it detects phantom threats due to obscured sensors. Car can brake from 65 to e.g. 40mph rapidly, causing more risk, due to the rapid deceleration. Car needs a basic cruise control feature | Crash: No Fire: No | Unknown |
| Feb 2022 | VEHICLE SPEED CONTROL,FORWARD COLLISION AVOIDANCE | We recently purchased a new Tesla Model 3. This vehicle has Tesla Vision and doesn't have the radar unit to assist with TACC or Autosteer. With this vehicle, it has phantom braking on a frequently basis. For example, I drive on a two lane highway and in a 20 mile drive in clear daylight the vehicle will phantom brake anywhere from 5-10 during the trip. These phantom braking vary from random light braking for no reason to full on hard braking. Fortunately, we've been lucky not to have anyone behind us when these incidents occur. I've contacted Tesla and given them multiple dates and times. I was told that they were able to look at some data on the car and it appears everything is working as it should and it "should" get better with updates. I was also given a bunch of excuses why it was working as it should. I even sent Tesla a video of it doing a hard phantom brake and i was told that the highway was narrow. I've argued with them that this is occurring every day on every drive when we are on a two lane highway. I basically get told that it's functioning as it should, which clearly it is not. When I tell them I owned a 2019 Model 3 and we had zero phantom braking issues with it, but they have no answers. I feel their go to answers are it's a software issue and blame the engineers, which us customers don't have access to. This is going to cause a crash one day if this issue isn't taken seriously. | Crash: No Fire: No | Unknown |
| Feb 2022 | FORWARD COLLISION AVOIDANCE | The car has been phantom braking wrecklessly since July and has not been fixed. It almost caused an accident yesterday morning on the way home from my work. There was a vehicle approaching in the oncoming traffic lane and the lights were on. My car slammed on its brakes causing the person behind me to swerve. If it is low light conditions and a car is approaching in the oncoming traffic lane my Tesla will phantom brake almost always. This started with the vision only vehicles as my past Teslas with radar did not do this. It is now impossible to drive in low light conditions even with cruise control without the car slamming on its brakes constantly in autopilot or cruise. | Crash: No Fire: No | Unknown |
| Feb 2022 | VEHICLE SPEED CONTROL,FORWARD COLLISION AVOIDANCE | What component or system failed or malfunctioned, and is it available for inspection upon request? - cruise control. How was your safety or the safety of others put at risk? - traveling at 55-60 mph on a 2 lane highway at night when the car suddenly put on brakes because it must of saw something but there was nothing. I believe this is called "ghost braking". There was a car behind us and had to slow down as well. Luckily no accident was caused but scared my wife and I. Has the problem been reproduced or confirmed by a dealer or independent service center? No. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? NO Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? It happened so fast I did not see any warning lights. The car just suddenly started to brake hard. | Crash: No Fire: No | Unknown |
| Feb 2022 | FORWARD COLLISION AVOIDANCE | Adaptive cruise control is becoming dangerous on two lane roads. It repeatedly tries to slam on the brakes as if there is an obstacle whenever a large truck or similar vehicle passes in the oncoming lane. It is dangerous to vehicles driving behind us and defeats the purpose of having adaptive cruise control. | Crash: No Fire: No | Unknown |
| Feb 2022 | FORWARD COLLISION AVOIDANCE | The car keeps abruptly braking between 10-20 mph speed reduction while at highway speeds. Seems to be when there's minor hills or curves but otherwise entirely open road without nearby vehicles. Happening in a 4 lane and 2 lane highway with cruise control set (not self driving or autopilot) and the autopilot, autosteer, forward collision warning, and automatic emergency braking options are all confirmed OFF. | Crash: No Fire: No | Unknown |
| Feb 2022 | VISIBILITY/WIPER | In December, Tesla released a software update that made Model 3 and Model Y cars unsafe to operate. They hid the defroster buttons and many other important controls behind menus that require multiple touchscreen presses to operate. This is unsafe to do while driving and as such we don't drive this car if the weather is at all suspect. The interface for safely operating a car should not rely on taking your eyes off the road to navigate touchscreen menus. Tesla has refused to roll back the software update and has promised a future update in the future to address some of these concerns. It's been over a month now. This needs immediate attention. | Crash: No Fire: No | Unknown |
| Feb 2022 | FORWARD COLLISION AVOIDANCE | This has happened frequently since I took delivery of the vehicle, I did have one repair request with tesla but they said they could not duplicate and the vehicle did not store enough data to confirm an issue. when driving with adaptive cruise control or cruise control with lane centering (autopilot) enabled the vehicle will SLAM on brakes (Like full emergency braking) with nothing in front of me. sometimes it chimes warning of a potential collision, sometimes it gives no visual or audible reason. It also will have more frequent events of mild to moderate braking. These events happen on interstates and two lane roads mostly but has also happened on multiple lane lower speed roads as well. it has gotten to where I do not use these features as I have almost been rear ended multiple times now due to these events. Tesla's general attitude to this was that it wasn't a big deal which i completely disagree. I have driven older teslas that still have a radar chip and it happens much less frequently and less severe on those. When I purchased the vehicle they informed me that the radar was no longer necessary and that it was to REDUCE these events. This happens from 20mph to 80+ all the way from 10 miles to the current 15,000 | Crash: No Fire: No | Unknown |
| Feb 2022 | VEHICLE SPEED CONTROL,FORWARD COLLISION AVOIDANCE | I've complained to Tesla as well. No known fix at this time. When Autopilot is engaged, it will pick up phantom objects and brake hard to avoid. I notice this happens mostly when passing semis, RVs, trailers. I see this happening on any turn where a vehicle is in the lane next to you or on the other side of the road. The latest one I had autopilot engaged, I was alone on the highway, and it braked hard for no reason. Brought me from 75-80 mph down to 20 mph in an instant. It then accelerated hard up to 80 again. Within a couple of seconds, it braked hard again down to 20 mph. Autopilot doesn't work. Tesla had no fix and their recommendation was to not use it anymore. I bought the Tesla for that reason. Full Self Driving is even worse. I'm afraid to use it because I have a delayed reaction in Full Self Driving mode. It is unsafe and it will cause an accident. | Crash: No Fire: No | Unknown |
| Feb 2022 | ELECTRICAL SYSTEM | On January 26th at about 4:30 pm pm on a clear day I was proceeding west at approximately 55mph on US33 between Barboursville and Ruckersville VA on a straight section of the road with a slight downward slope. I was not using cruise control. A tractor-trailer sized truck was going east and as it approached my Tesla braked hard, maybe maximally, and the panel flashed red, I think. I think I stepped on the brake pedal, but the braking ended instantly as the truck passed. There was no skidding or swerving. No car was close so there was no collision. There was no warning. The police were not called. I have not contacted the manufacturer - yet, as I assume it is a software problem that they are already working on. | Crash: No Fire: No | Unknown |
| Feb 2022 | VEHICLE SPEED CONTROL,FORWARD COLLISION AVOIDANCE | Any time I have the car in autopilot, it unexpectedly phantom brakes. Even when I'm not using autopilot, and I am using cruise control, the phantom braking still occurs. In several instances I have had people come close to hitting my car's rear. The braking is not subtle. It is rapid and aggressive. This issue creates a major danger for anyone in my car and others on the road. | Crash: No Fire: No | Unknown |
| Feb 2022 | SERVICE BRAKES | I have experienced several incidents of “phantom braking.” The brakes automatically apply, slowing the car abruptly, when there is no discernible reason. | Crash: No Fire: No | Unknown |
| Feb 2022 | FORWARD COLLISION AVOIDANCE | I was driving 65 on Highway 12 in California with the cruise control on and the car hit the brakes for no reason. I was not using autopilot, I was still controlling the steering. The car behind me had to slam on their brakes to avoid hitting me. This has happened several times and I am not afraid to use cruise control | Crash: No Fire: No | Unknown |
| Feb 2022 | FORWARD COLLISION AVOIDANCE | Car continues to have instances of phantom braking, no acknowledgment from Tesla regarding the issue. Occurs randomly and unpredictably, causing a serious safety hazard for cars following behind on the road. | Crash: No Fire: No | Unknown |
| Feb 2022 | SERVICE BRAKES,FORWARD COLLISION AVOIDANCE | While driving on the highway and using auto pilot it has had multiple instances of phantom brakes doing highway speeds it will slow cars down rapidly and for no apparent reason. Really needs to get corrected. | Crash: No Fire: No | Unknown |
| Feb 2022 | ELECTRICAL SYSTEM,FORWARD COLLISION AVOIDANCE | While using adaptive cruise control the car unexpectedly and unnecessarily brakes, rather sharply at times. This occurs especially frequently on two lane roads with curves and with trucks coming from the opposite direction. This does not occur, in my 6 months of owning this Tesla Model 3, on freeways. | Crash: No Fire: No | Unknown |
| Feb 2022 | VEHICLE SPEED CONTROL,FORWARD COLLISION AVOIDANCE | The car phantom brakes a lot. When sun is directly hitting from front, the car wouldn’t go in autopilot. The car phantom brakes on 1 lane streets a lot when there is a car coming from the front. When going the speed limit, it changes automatically to lower speed limits out of nowhere and is a hazard and dangerous because there are cars coming from the back and can hit the car when it reduces the speed very fast. Have submitted multiple phantom braking issues with Tesla with pressing and holding right scroll wheel but nothing has happened so far to correct this issue. When a big trailer changes lane and comes to the near lane of the car, the car thinks it’s going to hit the truck so it phantom brakes. | Crash: No Fire: No | Unknown |
| Feb 2022 | UNKNOWN OR OTHER,SERVICE BRAKES,FORWARD COLLISION AVOIDANCE | When the car is in assisted autopilot, the vehicle will brake very hard when not necessary. | Crash: No Fire: No | Unknown |
| Feb 2022 | FORWARD COLLISION AVOIDANCE | Car applied brakes while cruise control was engaged. There were no other vehicles around (either in front, approaching, or behind) | Crash: No Fire: No | Unknown |
| Feb 2022 | FORWARD COLLISION AVOIDANCE | Since about November Tesla has been doing random emergency braking both day and night in the middle of the highway almost causing numerous near miss accidents while on auto pilot. Also scaring the hell out myself and other passengers. It sends my dog in the back seat flying forward too. | Crash: No Fire: No | Unknown |
| Feb 2022 | VEHICLE SPEED CONTROL,FORWARD COLLISION AVOIDANCE | Our Tesla Model 3, while using the Adaptive Cruise Control, will apply full brakes with either nothing in the road ahead or with oncoming traffic on a 2-lane highway. This is extremely dangerous and a hazard to vehicles behind us. This occurs every time it is used, with frequency up to 4 times in a single minute. Tesla has cancelled 2 service requests this month stating this is normal operation. | Crash: No Fire: No | Unknown |
| Feb 2022 | FORWARD COLLISION AVOIDANCE | On several occasions, when the car was on cruise control and for no apparent reason, it suddenly braked from 70/65 mph to 30. Not only was this startling and frightening, it could have caused a rear-end collision, especially on Interstate 66 in VA where cars often follow too close. I contacted Tesla twice about the issue and set up a service appointment. Tesla cancelled the appointment the day before, saying they needed to have specific "time stamps" of the incidents. When I gave them a several day range, they said that wasn't specific enough, that I should drive the car and "time stamp" the next incident. Great idea, Tesla, for me to risk injury so they can get a "time stamp". In a word, they were dismissive and responded as if this were the first they'd heard of such a problem. It is a significant safety issue not only for the driver but for anyone in nearby cars.I have only had the car 4+ months and it terrifies me. The Washington Post had an article this week indicating this is a problem with many Teslas. Now I know I'm not alone. Would appreciate NHTSA's assistance in getting this safety issue resolved. | Crash: No Fire: No | Unknown |
