| Dec 2022 | SERVICE BRAKES,FORWARD COLLISION AVOIDANCE | This vehicle has the phantom braking issue whether you are using adaptive cruise or autopilot, and has happened at least 15 times in the past two years. Because of the sudden braking, we almost had a collision with a semi-truck coming up behind us on I-5 heading south the last time and the driver thought I was brake-checking him, making him very angry and giving obscene gestures at us for it. We reported it to the Tesla service center, and they basically said it happens, and they disclosed it in the operator manual. That is unacceptable. This is very dangerous, and lives could be lost in the circumstance where someone is following close behind. Tesla basically is saying it can happen and there is no fix which absolutely unacceptable and this car is dangerous to drive. | Crash: No Fire: No | Unknown |
| Dec 2022 | FORWARD COLLISION AVOIDANCE | While using the autopilot function car unexpectedly brakes almost to a stop for no apparent reason. This happened in different driving conditions, day, night, other cars around and on empty roadways, both divided and connected two and four lane freeway and side highways. Brakes so hard that objects fly off the seat and cars traveling behind my vehicle have had to break themselves and or change lanes. | Crash: No Fire: No | Unknown |

My car is totaled. | Crash: Yes Fire: No | Unknown |
| Dec 2022 | VEHICLE SPEED CONTROL,FORWARD COLLISION AVOIDANCE | Phantom braking: While in cruise or autopilot mode, it suddenly brakes on freeway without any obstacles observed. | Crash: No Fire: No | Unknown |
| Dec 2022 | FORWARD COLLISION AVOIDANCE,ELECTRICAL SYSTEM | The contact owns a 2020 Tesla Model 3. The contact stated that while driving at an undisclosed speed on the highway, the vehicle was experiencing phantom braking. The contact stated that the failure reoccurred while driving at various speeds with the cruise control or while using the autonomous self-driving feature. The contact stated that the battery warning light was illuminated. The vehicle was not taken to an independent mechanic or local dealer to be diagnosed or repaired. The manufacturer was not made aware of the failure. The failure mileage was unknown. | Crash: No Fire: No | Unknown |
| Nov 2022 | FORWARD COLLISION AVOIDANCE | The contact owns a 2020 Tesla Model 3. The contact stated that while utilizing the ADAS features including the Adaptive Cruise Control, the vehicle independently applied the brakes while driving at highway speeds. No warning lights were illuminated. The vehicle was not diagnosed. The vehicle was not repaired. The dealer nor the manufacturer was notified of the failure. The failure mileage was approximately 25,000. | Crash: No Fire: No | 25,000 |
| Nov 2022 | FORWARD COLLISION AVOIDANCE | 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 | Crash: No Fire: No | Unknown |
| 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 | 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 |
| 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 | 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 |
| 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 |
