| Date | Component | Summary | Severity | Mileage |
|---|---|---|---|---|
| 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 | 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 | 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 | 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 | 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 | 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 | 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 | 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 | 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 | 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 | 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 | 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 | 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 | VEHICLE SPEED CONTROL | I've had 2 incidents of phantom braking in 13 months of ownership. Both times when using cruise control. Scary stuff. | Crash: No Fire: No | Unknown |
| Feb 2022 | FORWARD COLLISION AVOIDANCE | When vehicle is in full self drive mode, sometimes it mistakenly detects an obstacle on the highway and applies brakes. This event presents risk of getting rear ended at high speed on highways. | Crash: No Fire: No | Unknown |
| Feb 2022 | FORWARD COLLISION AVOIDANCE | When driving in several locations near my home, with cruise control engaged (not full driving, just cruise control), the car will suddenly slow to ~20mph and stay at that speed for a few moments, and then accelerate back up to the legal speed limit of 55mph, 60mph, etc. There are no objects on or near the road, no other cars, and it appears to be a problem with the software that identifies if there is an object in the road to automatically reduce speed or slow down. There are no warning chimes, no feedback to the driver of the reason to slow down, no posted speed limit signs, etc. I can duplicate this every time I traverse these roadways. One of the most significant reasons I purchased this vehicle was it's advertised safety features like emergency braking and such. However, with this problem, I either have to disable the auto-braking feature, or not use the driving assist features (like cruise control). This is a significant issue for me, and I have no doubt going from a 60mph roadway to 20mph for no reason will result in me getting rear-ended or at the very least cause problems for drivers behind me. | Crash: No Fire: No | Unknown |
| Feb 2022 | FORWARD COLLISION AVOIDANCE | When using the adaptive cruise control on the vehicle, which is the only cruise control there is, the car will often brake hard for no reason, or inappropriate reasons. This most recent incident was a two lane highway (one lane each direction) where oncoming cars who were in their lane would cause the car to think a collision was imminent, start beeping, and brake hard. Another incident appeared to brake for shadows, but I am unsure! Overall the experience, and experiences of many other Tesla owners facing similar problems has caused me to just be unable to use cruise control at all as I fear it could cause an accident. | Crash: No Fire: No | Unknown |
| Feb 2022 | FORWARD COLLISION AVOIDANCE | Driving on the interstate in autopilot with nobody in front of me but there was somebody riding my rear. And the vehicle decided to phantom break which almost caused the guy to rear end me while going 75 mph it could have been lethal. | Crash: No Fire: No | Unknown |
| Feb 2022 | SERVICE BRAKES,FORWARD COLLISION AVOIDANCE | When driving at low speeds (below35) we have had 2 instances of the car braking with no obstacles. | Crash: No Fire: No | Unknown |
| Feb 2022 | SERVICE BRAKES,FORWARD COLLISION AVOIDANCE | While driving in cruise control, my Tesla 3 braked for no reason. No accident occurred because no one was behind me. It has happened about 10 times. It has not been confirmed by a dealer because I do not live near a dealer. It has not been inspected by the manufacturer, police or insurance representatives. No warning lights or messages appeared to warn me. | Crash: No Fire: No | Unknown |
| Feb 2022 | FORWARD COLLISION AVOIDANCE | 1st incident Driving on a 2 lane road @ 55MPH with no oncoming traffic emergency braking occurred (with all the warning lights and sounds) with no obstacles in my path. 2nd incident driving on a 8 lane highway @65 MPH (I-71) with very little traffic (and no oncoming obstacles) emergency braking occurred (with all the warning lights and sounds) no obstacles in my path. 3rd incident driving on a different 2 lane road @ 45 MPH emergency braking occurred (with all the warning lights and sounds) no obstacles in my path. I have only owned the vehicle 2.5 months and less the 1300 miles on the odometer. | Crash: No Fire: No | Unknown |
| Feb 2022 | FORWARD COLLISION AVOIDANCE | When using traffic aware cruise control or auto steer the car phantom breaks and issues warning chimes when it senses large vehicles approaching on undivided 2 lane roads. The car also phantom brakes when it misidentifies shadows on these same 2 lane roads. I have almost been rear ended by closely following traffic several times. This has been happening since new. We have been patient, hoping a software update would fix this very well known problem. | Crash: No Fire: No | Unknown |
| Feb 2022 | VEHICLE SPEED CONTROL,SERVICE BRAKES,FORWARD COLLISION AVOIDANCE | 1. Vehicle brakes for no reason while on Traffic Aware Cruise Control 2. At night on come head lights appear to cause braking while on Traffic Aware Cruise Control. 3. Vehicle brakes for no reason when on Traffic Aware Cruise Control when on two lane road (one lane each direction) when on coming large vehicle approaching. 4. Vehicle brakes for no apparent reason while on Traffic Aware Cruise Control when light conditions cause high contrast shadows on the road. | 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 |
