| Nov 2022 | FORWARD COLLISION AVOIDANCE | "Phantom braking" issue. When car is in autopilot or enhanced autopilot mode (an upgrade I purchased after I bought car), will brake suddenly and firmly at high speed for no apparent reason. Until September 2022 car would very occassionally brake too easily in autopilot mode (perhaps 3 times in two years), but it was not sufficiently forceful or frequent to cause alarm. However, on 9/26/22 and 9/30/22 during daytime driving car violently braked on highway at least 6 times over approx 500 miles of driving. Fortunately, these incidents caused no damage, collision, or injury. There was little additional traffic on the road at the time. However, items in car, and two cats in carriers on back seat were thrown forward and displaced, and the incidents were very frightening. When I realized this was happening in autopilot modes, I stopped using feature completely and have not since. At 11/19/22 service appt for issue at Alhambra Tesla dealer I was told this was a "known issue" with no current solution; however, I was told that the more I used autopilot and hit accelorator during phantom braking, the faster car would "learn" not to do this. Given that taking the risk of continuing to use autopilot at all poses a serious risk of injury, I am truly shocked at the suggestion that I continue to use this feature and essentially train my car not to be dangerous. Via Tesla app I gave information and dates to Tesla prior to service appt and was told that they would attach vehicle log to file for service visit. | Crash: No Fire: No | Unknown |

| Nov 2022 | SERVICE BRAKES,FORWARD COLLISION AVOIDANCE | When using autopilot cruise control, the car will brake hard for no apparent reason. I only use cruise control on limited access highways. When this happens, I immediately disengage cruise control and drive manually. This can happen at any time. I have driven the car cross country several times, driving all day. Some days it won’t happen at all, and on some days it can happen several times. I’m concerned that if someone is close behind me, they could hit me from behind. This has been happening for the past two years | Crash: No Fire: No | Unknown |
| Nov 2022 | SEATS,AIR BAGS | The driver seat occupancy weight sensor has to be replaced twice now. The car does not recognize someone is in the driver seat. It is unclear whether the airbags would deploy if I was in an accident as the car is unsure if someone is even inside. When I get out of the car it stays on. When I put it into reverse without having the seatbelt on it slams on brakes. | Crash: No Fire: No | Unknown |
| Nov 2022 | FORWARD COLLISION AVOIDANCE | phantom braking/slowing. Also, please do what you can to stop deployment of FSD by the end of 2022. Not only is the car and drivers not ready for it, the infrastructure is not as well. In addition, the 100% reliance of cameras for auto aware CC and FSD is absolutely flawed. Tesla must add radar—better yet, LiDAR—to their vehicles irrespective of FSD but, absolutely for FSD if they insist on pushing it before drivers, infrastructure, and the vehicles are ready for it. My opinion, FSD should never be allowed on any vehicles—maybe by the 22nd century… | Crash: No Fire: No | Unknown |
| Nov 2022 | STRUCTURE | The 2020 Model 3 uses a fiberboard front skid plate, that is intended to protect coolant lines that protect the battery. When wet, the fiberboard front skid plate degrades and exposes the coolant lines to damage from road debris, which could lead to a battery fire. Attached are photos of this damage. Tesla should be required to use a sturdier material to protect against this risk, and replace existing fiberboard front skid plates with the sturdier material. | Crash: No Fire: No | Unknown |
| Nov 2022 | UNKNOWN OR OTHER,SERVICE BRAKES,FORWARD COLLISION AVOIDANCE | Ever since a recent software update was downloaded and installed, my Model 3's incidence of "phantom braking" events while using traffic aware cruise control/autopilot has gone up by a very noticeable degree. It has always been a known issue, however since the redundant safety systems (radar and ultrasonic sensors) on my model year vehicle were disabled by one of the recent updates, phantom breaking events that can possibly CAUSE a collision event or loss of control of the vehicle happens far more frequently. Instead of occurring once every 1000 or so miles, it now occurs two or three times every 250 or so miles, judging from performance on recent cross-state road trips. My car does not use the "Full Self Driving" package that Tesla offers. | Crash: No Fire: No | Unknown |
| Nov 2022 | SERVICE BRAKES,FORWARD COLLISION AVOIDANCE | Phantom braking when using cruise control. Happens practically daily, but most recently this morning at 9:25am. | Crash: No Fire: No | Unknown |
| Nov 2022 | UNKNOWN OR OTHER,LANE DEPARTURE | Side repeater camera are blurred because of light at night. Cannot see when switching lanes | Crash: No Fire: No | Unknown |
| Nov 2022 | STEERING,EXTERIOR LIGHTING,LANE DEPARTURE | This cocksucker blasts oncoming traffic with DISCO HIGHBEAMS every single fucking time there's a lonely oncoming car on the highway. Someone's gonna shoot my ass for blasting them repeatedly with highbeams. Because autosteer is connected to auto highbeams, I can't turn it off unless I turn autosteer off and drive like a 1995 peasant. | Crash: No Fire: No | Unknown |
| Nov 2022 | UNKNOWN OR OTHER,LANE DEPARTURE | The turn signal is attached to the left and right side blindspot camera. When using the blind spot camera at night, the turn signal light “bleeds” into the camera blocking your view. So it becomes a safety issue when switching lanes at night, especially on a dark freeway. I have contacted Tesla and stated that “the camera performance on older vehicles is neither a defect of materials nor workmanship… which is has been enhanced in newer vehicle production. “ | Crash: No Fire: No | Unknown |
| Nov 2022 | VEHICLE SPEED CONTROL,FORWARD COLLISION AVOIDANCE | Traveling on a clear, dry highway on a sunny morning and once again the next day we experienced phantom braking. This occurred three times in two days. In all cases we were traveling at 75mph and were using the adaptive cruise control. In all cases there were reflections in the road from the heat mirage or from something far down the road. The car acted as if it saw something in the road and braked sharply. The driver had to accelerate to override the braking. | Crash: No Fire: No | Unknown |
| Nov 2022 | ELECTRICAL SYSTEM | The car broke down completely saying that "Electrical system failure". It is immobile. This is dangerous as I was driving on the freeway and it suddenly started showing lot of warnings. Warning included "12v power system failure", "Electrical system failure". "Brakes might not work". Somehow I got in to the garage and the car is now immobile. It does not even lock. It is in the same condition as I parked. Cannot open other doors. This could have been life threatening if it had stopped on the freeway. With the price and safety rating, I never expected Tesla to have total failure. | Crash: No Fire: No | Unknown |
| Oct 2022 | FORWARD COLLISION AVOIDANCE | This vehicle has frequent episodes of phantom braking at highway speeds. No obstacles, stop lights or other vehicles in proximity | Crash: No Fire: No | Unknown |
| Oct 2022 | FORWARD COLLISION AVOIDANCE | Last March we drove to Tampa Florida and on 3 occasions using cruse control the car came almost to a stop felt like I hit brakes very hard. each time we were in the middle of a highway with no cars around us. I called Tesla they said do report a bug. The weird thing is each time it was at dusk. I just read an article and thought to report it. I am not sure if Tesla reported it. It has not happened in the last 6 months but very scary when it happens. | Crash: No Fire: No | Unknown |
| Oct 2022 | FORWARD COLLISION AVOIDANCE | Phantom braking has occurred numerous times on cruise control. No cars or other objects nearby. Set up appointment with Dealer but the service dept said they are aware of the issue and at this time nothing can be done. | Crash: No Fire: No | Unknown |
| Oct 2022 | FORWARD COLLISION AVOIDANCE | While in cruise control the car baraked excessively on a straight 4 lane divided highway even though there was no other vehicles in front, to the side or coming on the opposite direction. This happened on 101 north of Paso Robles | Crash: No Fire: No | Unknown |
| Oct 2022 | ELECTRICAL SYSTEM | The 12 volt battery on my T2020 Tesla Model 3 failed without warning last week when I entered the driver's side and closed the door. There was a very brief warning on the control screen that the "12 volt battery should be replaced soon." Then the screen went blank and all controls to the car were rendered inoperable. I could not open the door. I had to go on line on my mobile phone to the Tesla website to get the manual to remind myself how to use the mechanical latch on the door. I then exited the car, and could not re-enter the car. My biggest concern is that if a child or an animal were in the back seat there would be NO WAY to get them out without breaking a window. The Tesla technician came the next day to change the 12 volt battery. To do this on a Tesla Model 3, he first had to use an external 12 volt battery to open the "frunk", which he did. However, the car's 12 volt battery was so dead that he could not jump it. He then had to "break in to the car" by inserting a pneumatic pillow into the driver's side window so that he could insert a coat hangar he made himself (he told me Tesla does not supply them!). It took him about an hour of fumbling before he was able to open the mechanical latch on the driver's door; this allowed him to disconnect the main battery unit below the rear seat so he would not be electrocuted when he changed the 12 volt battery in the frunk. So even if I had had a set of jumper cables and an eternal battery at the time the car's 12 volt battery failed, I would have had to break a window to get into the car to rescue a child or animal who might have been trapped in the car. This is clearly a design flaw that should be corrected to improve the safety of a car that I otherwise like very much. I should mention that the Tesla technician said he was seeing a lot of these 12 volt battery failures; he had 4 more to address that very day. Thank you. | Crash: No Fire: No | Unknown |
| Oct 2022 | FORWARD COLLISION AVOIDANCE | I had 2 incidents of "phantom braking" in the vehicle this past week. I was just in cruise control, and the roads were in good condition, visibility and skies were clear, there were no cars in front or behind me, and we were cruising about 70 mph. In 2 cases, the car just slowed by itself for a few seconds and then I disengaged the cruise control. In 1 other cases, the car made an abrupt braking from 70 to about 40 mph. I disengaged and then did not use cruise control any longer. I've been told by Tesla service that the car's "radar" feature was replaced/disengaged in lieu of Tesla Vision, which apparently is in "beta" phase. In any event, this should not be happening, especially in just basic cruise control under ideal road conditions. | Crash: No Fire: No | Unknown |
| Oct 2022 | VEHICLE SPEED CONTROL,FORWARD COLLISION AVOIDANCE | While driving on an open highway using the Tesla Auto Pilot (Adaptive Cruise Control, NOT Full Self Driving), we experienced 3 separate instances of unexpected braking. In each case, we were on flat terrain with no vehicles in front of us for hundreds of yards. The weather was sunny and warm with few clouds in the sky. We were driving westbound between 10am and 1pm at the time of the incidents. During the first incident, the vehicle began to brake sharply and violently enough to startle, awake and scare a sleeping adult passenger in the front passenger seat. From memory, the braking rapidly dropped our speed by 15-20 mph. Thinking it was a simple glitch, I attempted to re-engage the system two more times and the same type of behavior occurred each time. I drove the remaining hours of our drive without engaging Auto Pilot. After researching the issue following the drive, I learned of the "phantom braking" issue many customers have reported. We then reported the issue to Tesla and created a service appointment to check out the vehicle. Tesla responded back that the ran a full remote diagnostic and the vehicle has no hardware issues reported by any sensors and said the service appointment was unnecessary because there was nothing to look at. | Crash: No Fire: No | Unknown |
| Oct 2022 | FORWARD COLLISION AVOIDANCE | Car randomly apply brakes when no obstacle present while Auto Pilot is engaged. Also gives a lot of false collision warnings. | Crash: No Fire: No | Unknown |
| Oct 2022 | VEHICLE SPEED CONTROL,FORWARD COLLISION AVOIDANCE | Driving on cruise control (not autopilot), in the following conditions: on an interstate highway with all lanes in the traveling direction clear, no obstructions and no traffic to the front or to either side of the car, on a straight road with no bridge or on or off ramp in front of the car, daylight and no rain or or other participation, the car can unexpectedly and without warning aggressively brake. If the driver does not immediately regain control of the speed (by pressing the accelerator, or turning off the cruise control) the braking has caused the speed of the car to go from 75mph to 30mph. Unlike other Tesla accident avoidance features, the braking occurs with no indication that an obstruction is being avoided. I have owned the car since it was new and until Saturday 8 October 2022, the adaptive cruise control worked as expected. Since that Saturday (less than a week) the braking has occurred several times. Each time it required a sudden depress of the accelerator pedal to recover speed control of the car. The first photo I've attached shows a screengrab of the moment of one deceleration on Monday 10 October saved as a dashcam video. As you can see there is no obstruction and no other traffic around the car at the time. The second photo is a snapshot of the chat session I had with Tesla service where they claim that this behavior is caused by a curve, off ramp, a bridge, a two lane road. As you can see in the first photo, none of this is the case. | Crash: No Fire: No | Unknown |
| Oct 2022 | FORWARD COLLISION AVOIDANCE | The contact owns a 2020 Tesla Model 3. The contact stated while driving 75 MPH with the cruise control activated, the vehicle experienced phantom braking. The vehicle was not diagnosed nor repaired by an independent mechanic or dealer. The manufacturer was made aware of the failure and informed the contact that a technician would inspect the vehicle at the residence. The failure mileage was 26,498. | Crash: No Fire: No | 26,498 |
| Oct 2022 | FORWARD COLLISION AVOIDANCE | Autopilot has repeatedly slowed down very quickly and suddenly on multiple occasions over the past year for no reason on a completely clear road. It’s the same “phantom braking” issue as described in this article: https://www.cbsnews.com/news/tesla-phantom-braking-nhtsa-750-complaints/ | Crash: No Fire: No | Unknown |
