| Date | Component | Summary | Severity | Mileage |
|---|---|---|---|---|
| Nov 2021 | VEHICLE SPEED CONTROL,SERVICE BRAKES,FORWARD COLLISION AVOIDANCE | Whenever TACC (cruise control) is engaged and the car is on a two lane highway with no divider, it will aggressively brake and trigger the collision warning system when a semi-truck passes going the opposite direction. | Crash: No Fire: No | Unknown |
| Nov 2021 | FORWARD COLLISION AVOIDANCE | While using autopilot feature on interstate highway the vehicle independently applied braking while traveling at 70 mph although no other vehicle nor any other physical object was observed. Also while using the same feature and traveling on a two lane highway at 55 mph the car independently applied braking when an large truck approached in the opposite on-coming lane. This exact event happened a second time when another large truck while traveling the same two lane highway. Autopilot was no longer used. | Crash: No Fire: No | Unknown |
| Nov 2021 | FORWARD COLLISION AVOIDANCE | The “traffic aware cruise control” feature is flawed to the point of being unusable add dangerous. My Model 3 (leased in late September 2021) exhibits very frequent “phantom braking” problems when TACC is active. Some are mild, the car applying the brakes and slowing down despite the absence of nearby cars or hazards. Some are dramatic, the car slamming on its brakes and sounding an alarm — again, with no hazards. I have a service appointment scheduled for Dec 3 but I’m not optimistic. | Crash: No Fire: No | Unknown |
| Nov 2021 | FORWARD COLLISION AVOIDANCE | For the past week, my car phantom braked with no obvious danger from a parked car. It just happens on a city road, not a freeway. Ithappened about 4 times | Crash: No Fire: No | Unknown |
| Nov 2021 | FORWARD COLLISION AVOIDANCE | TRAFFIC AWARE CRUISE CONTROL WHILE CRUISE CONTROL IS OPERATING, DRIVING AT 70 MPH OR HIGHER, FOR NO APPARENT REASON, NO VEHICLES AHEAD OF ME, THE CAR BRAKES SUDDENLY. THIS HAPPENED AT LEAST SIX TIMES ON A 1000 MILE TRIP. IF A CAR HAD BEEN FOLLOWING TOO CLOSELY, MY SUDDEN BRAKING COULD HAVE CAUSED AN ACCIDENT. I HAVE NOT FIGURED OUT HOW TO CONTACT TESLA ABOUT THIS. NO ONE HAS INSPECTED MY CAR. THERE WERE NO WARNING SIGNS. AFTER I GOT HOME, I GOOGLED THE PROBLEM AND SAW THAT OTHERS HAD EXPERIENCED IT TOO. I'M WRITING IN THE HOPE THAT YOU WILL TELL TESLA TO FIX THE PROBLEM, OR AT LEAST TO OFFER THEIR CUSTOMERS PLAIN CRUISE CONTROL WITHOUT THE TRAFFIC AWARE FEATURE. THIS HAPPENED EVERY TIME I WAS ON THE INTERSTATE FOR MORE THAN A COUPLE HOURS, MOST RECENTLY ON OCTOBER 31, 2021. | Crash: No Fire: No | Unknown |
| Nov 2021 | FORWARD COLLISION AVOIDANCE | While driving on C-470 westbound going 70 MPH with the car on Autopilot, the car braked hard dropping the speed to 40 MPH. If a car would have been behind me, they would have hit the back of my car. This issue is happening frequently, from neighborhood side streets, city streets, and on the interstate highway. | Crash: No Fire: No | Unknown |
| Nov 2021 | FORWARD COLLISION AVOIDANCE | Traffic Aware Cruise Control in the 2021 Model 3 is down right dangerous. Constant random braking for no reason at all. Happens multiple times if I use TACC on 2 lane roads. Happens nearly every time I use TACC on a 4 lane road. If I have traffic behind me I cannot use TACC at all for fear I would be rear ended. | Crash: No Fire: No | Unknown |
| Nov 2021 | VEHICLE SPEED CONTROL,FORWARD COLLISION AVOIDANCE | "Traffic Aware Cruise Control" (aka Autopilot) applied full braking and sounded collision warning when no collision was imminent. Had traffic been following closely, a rear-end collision could have occurred. Several other similar "ghost braking" incidents have occurred but this was the worst and most dangerous. Vehicle has not yet been taken to a repair facility. Vehicle has not needed inspection by law enforcement nor insurance company. | Crash: No Fire: No | Unknown |
| Nov 2021 | FORWARD COLLISION AVOIDANCE | I have been experiencing very frequent adaptive cruise control breaking for no reason. It is getting worse with every software update. It seems like the car is very scared of oncoming traffic and will hit the breaks or slow down for no reason. Sometimes there will be no traffic at all and it happens. If a car is following closely I’m afraid I will be hit. I wish I could turn off adaptive cruise control but there is no option. This is a serious safety issue. | Crash: No Fire: No | Unknown |
| Nov 2021 | VEHICLE SPEED CONTROL,SERVICE BRAKES,FORWARD COLLISION AVOIDANCE | Starting in June 2021, Tesla removed the radar sensing on their vehicles and switched to a vision-only (camera) system for adaptive cruise control and "auto pilot" operation. On my 2021 Model 3 Performance, I can not use either system without constant "phantom braking" events. Sometimes it will only gently pulse the brake pedal, but often it is very hard braking along with a beep and message on-screen saying I need to take immediate control of the car. This happens daily and is not hard to reproduce. If there is a car behind you, it can be quite dangerous. Even if they don't rear end you, often it will cause them to think you're doing a "brake check" and can lead to road rage incidents. My previous car (a 2018 Model 3 RWD) had a radar sensor and experienced mild (not hard) phantom braking roughly 2~3 times over an 18 month period. I still have access to that car and recently tested it for comparison. Even on the same software revisions, the old car drove flawlessly on ACC and Autopilot modes. | Crash: No Fire: No | Unknown |
| Nov 2021 | ELECTRICAL SYSTEM | The contact owns a 2021 Tesla Model 3. The contact stated that while the vehicle was in full auto-drive mode approximately 10-15 MPH, the vehicle lost motive power. The contact was able to restart the vehicle. The vehicle was not diagnosed or repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 2,300. The VIN was unavailable. | Crash: No Fire: No | 2,300 |
| Nov 2021 | FORWARD COLLISION AVOIDANCE | I was using auto pilot. The road was pretty empty single lane road. There was no car in front of me or coming in opposite direction. The car automatically slammed the brake pretty hard. We were lucky enough no one rear ended us. Looks like a software bug in Tesla. Please investigate. I will never ever again use this [XXX] auto pilot and risk my family life. INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6). | Crash: No Fire: No | Unknown |
| Nov 2021 | LANE DEPARTURE | I was driving on FSD Beta but when an alien landed on the road in front of me. The FSD Beta software did not detect the alien’s vehicle and almost hit her as she was stepping out. System initiated beeps and I tried to take control but it forced control away from me and tried to steer towards the alien. I had to kick the car to get control back. Very dangerous to everyone involved. | Crash: Yes Fire: No | Unknown |
| Nov 2021 | VEHICLE SPEED CONTROL,FORWARD COLLISION AVOIDANCE | Autopilot constantly brakes due to automatic emergency braking on two-way highways at night. Every time a car passes in the other direction, the car starts braking, often as soon as the headlights are visible. This is a significant safety issue and resulted in me disabling AEB, which re-enables automatically every time I drive. I needed to go out of my way and ensure no one was tailing me because the car would brake check them. This wasn't an isolated incident. Every time I've been on a two way highway and sometimes even on multi-lane unlit highways, I have these braking issues constantly. I was driving under the speed limit. | Crash: No Fire: No | Unknown |
| Nov 2021 | FORWARD COLLISION AVOIDANCE | When driving using the traffic aware cruise control, the vehicle experiences frequent abrupt and random rapid deceleration. This causes a safety issue when other vehicles are behind due to the rapid change in speed. Occasionally the vehicle will produce a forward collision warning with nothing in the path of the vehicle. This makes the cruise control function less usable and no option to disable the adaptive function. | Crash: No Fire: No | Unknown |
| Nov 2021 | FORWARD COLLISION AVOIDANCE | Car hits the brakes and activates the emergency braking and forward collision warning very frequently (10+ instances during a 1 hr drive) in instances that absolutely do not warrant it (no obstacles or cars in the lane of traffic). Product is unsafe in the condition that it is in, and car offers no way to revert to standard cruise control. This type of automatic behavior could cause accidents. | Crash: No Fire: No | Unknown |
| Nov 2021 | VEHICLE SPEED CONTROL,SERVICE BRAKES,FORWARD COLLISION AVOIDANCE | Vehicle slams brakes on with on coming traffic when cruise control activated. Have attempted to contacted Tesla several times. Tesla actually canceled a mobile service stating they did an update to fix the issue. It did not. In fact it made the problem worse. The are not answering my emails or texts, calling the service line does no good the say they can’t see the issue in their data | Crash: No Fire: No | Unknown |
| Nov 2021 | FORWARD COLLISION AVOIDANCE | When I use cruise control, the car will brake suddenly sometimes very fast or moderate braking. There is no reason for the car to break. It happens on 2 lane roads and 4 plus lanes. I can not determine if tree shadows cause it. It often breaks when a car is coming from the opposite direction on a curve. It also breaks during the night on a 2 lane road when a car comes from the opposite direction. Sometimes it has freaked so hard that if anything is on the seat, it is thrown toward the floor. I fear I could be hit from behind due to unnecessary braking, so I will only use cruise control if there is little or no traffic on on roads with 4 or more lanes. | Crash: No Fire: No | Unknown |
| Nov 2021 | UNKNOWN OR OTHER | Tesla is now making interactive video games and live internet web searching possible on the main front seat display WHILE THE CAR IS DRIVING. The video games are allegedly restricted only to passengers. Web browsing is available to anyone at any time. Why is a manufacturer allowed to create an inherently distracting live video which takes over 2/3 of the screen which the driver relies on for all vehicle information? Tesla has no gauges above the steering wheel. NHTSA needs to prohibit all live video in the front seat and all live interactive web browsing while the car is in motion. Creating a dangerous distraction for the driver is recklessly negligent. | Crash: No Fire: No | Unknown |
| Nov 2021 | VEHICLE SPEED CONTROL,SERVICE BRAKES,FORWARD COLLISION AVOIDANCE | I noticed you have a recall for SOME Teslas about a glitch with the auto braking after latest Beta FSD rollout. My Tesla has had this since day one, and I don't have or use FSD. I do use the adaptive cruise control, and that is when I have problems with my car slamming on the brakes for no reason. I have been lucky, 3 times I have ALMOST, been rear-ended. I have had it in the shop a couple times for the issue, and they tell me to read the manual and the car is fine. I have talked with 5 other Tesla owners, and they have all had the problem of their car slamming on the brakes for no REAL reason. I think the GLITCH is a bigger problem than Tesla is willing to admit, and applies to most Tesla cars. there are even website forums about, "Phantom Braking", which is lingo for the same thing | Crash: No Fire: No | Unknown |
| Oct 2021 | FORWARD COLLISION AVOIDANCE | System erroneously sounded forward collision warnings about once per minute. Automatic Emergency braking faulted and could not be enabled. Firmware version 2021.36.5.2 | Crash: No Fire: No | Unknown |
| Oct 2021 | AIR BAGS | Car accident , car failed to deploy airbags . | Crash: Yes Fire: No Towed | Unknown |
| Oct 2021 | SERVICE BRAKES, HYDRAULIC,SERVICE BRAKES | break backing plate screw loosened and go into the break disk. it create noise when driving and breaking. the loosened screw might the damage the break rotor. the screw was removed from the break disk and tighten again by independent service center The manufacturer have inspected no warning lamps but it create noise. so it is not hard to detect this issue. it first appear on 19 Oct and I have the service center fix it right the way. | Crash: No Fire: No | Unknown |
| Oct 2021 | FORWARD COLLISION AVOIDANCE | My vehicle is a "Tesla Vision Only" (non-radar) Model 3 on firmware 2021.32.21 although this issue occurred on other firmware I've used as well. At night the car will very very frequently brake 3-10 miles an hour for no reason. It's specifically bad at night. It regularly thinks the ongoing traffic is headed in my lane. It regularly slows me down significantly before the top of a hill. Sometimes this can happen 3-5 times in succession within 5 minutes and causes other drivers to react to my vehicle as if it were dangerous. My only recourse is to tap the accelerator as quickly as I can to override the braking or not use the cruise control. This happens mostly on two lane two way traffic roads, often with gentle curves, and worst at night. I now have a car without even "dumb" cruise control. This is not what you think you're buying when you get a brand new $50k vehicle. When I originally received the vehicle in June I had brought up my experience to a technician while they were servicing the vehicle for other purposes they told me that there doesn't appear to be anything wrong with the camera system and that with more firmware updates it would get better. It is not better, I'd say it's gotten worse since I bought the vehicle. | Crash: No Fire: No | Unknown |
| Sep 2021 | ELECTRICAL SYSTEM,EXTERIOR LIGHTING | 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. | Crash: No Fire: No | Unknown |
