| Nov 2022 | WHEELS | The TPMS alerted me that the front driver tire was low at 36 psi. Pulled into gas station within a mile from initial alert and when I unscrewed the valve cap the valve stem broke and shot out of the tire and the tire deflated. The components were found and are available for inspection. The car has not been repaired yet and is currently at the Tesla Service Center in Agoura Hills at 28721 Bldg A Canwood Street Agoura Hills, CA. I drive two children under 5 and am lucky this did not occur at high speeds or while the vehicle was in operation at any speed. There is no reason this should have happened. There was no prior damage to the wheel or tire. | Crash: No Fire: No | Unknown |
| Oct 2022 | FORWARD COLLISION AVOIDANCE | During a road trip from Oklahoma to California and back my Model 3 suddenly and abruptly braked coming almost to a stop on up highway while cruise control was engaged. The braking was such that it caused occupants to lunge forward and seatbelts pretension. This aggressive braking is a common occurrence with Tesla and has been called “phantom braking”. This is not the first time this has happened to me. This is a recurring issue | Crash: No Fire: No | Unknown |
| Oct 2022 | FORWARD COLLISION AVOIDANCE | The contact owns a 2021 Tesla Model 3. The contact stated while driving 70 MPH up a hill, the vehicle made a sudden stop without any warning, causing the contact and his wife go forward in their seats. The contact accelerated and the vehicle continued to operate normally. The vehicle was not diagnosed. The dealer was not contacted. The manufacturer was contacted and stated that the computer needed to be checked. The failure mileage was 4,100. | Crash: No Fire: No | 4,100 |
| Oct 2022 | LANE DEPARTURE,BACK OVER PREVENTION,FORWARD COLLISION AVOIDANCE | In vehicle speaker system occasionally resets, keeping speakers from making noise during a 5-10 second window. This keeps in-vehicle chimes and collision warnings from sounding at appropriate volumes. | Crash: No Fire: No | Unknown |
| Oct 2022 | STRUCTURE | The contact owns a 2021 Tesla Model 3. The contact stated while driving 10-15 MPH through standing water, he heard an abnormal sound coming from the rear of the vehicle. The contact stated that upon parking the vehicle, he noticed that the rear bumper had separated from the frame. The contact found the rear bumper on the ground a block away from his residence. The vehicle was taken to a Tesla Service Center who informed the contact that the failure was caused by water damage. The vehicle was not repaired. The manufacturer was notified of the failure but provided no assistance. The manufacturer advised the contact to take the vehicle to an auto collision repair shop where the vehicle could be repaired by his insurance provider. The failure mileage was approximately 59,800. | Crash: No Fire: No | 59,800 |
| Oct 2022 | FORWARD COLLISION AVOIDANCE | The contact owns a 2021 Tesla Model 3. The contact stated while driving 80 MPH with the cruise control activated, the vehicle inadvertently decelerated to 20 MPH and experienced phantom braking. The vehicle was not diagnosed nor repaired by an independent mechanic or dealer. The manufacturer was made aware of the failure. The failure mileage was approximately 15,000. | Crash: No Fire: No | 15,000 |
| Oct 2022 | ELECTRICAL SYSTEM,UNKNOWN OR OTHER | Driver side window fails to lock completely upon locking the car manually and/or using auto walk away function. This leaves the car very much unsecure and open to being vandalized. Additionally, the driver sides window fails to close fully when auto close button is pressed. The driver side window button has to be fiddled with few times to get a complete window seel. | Crash: No Fire: No | Unknown |
| Oct 2022 | VEHICLE SPEED CONTROL,FORWARD COLLISION AVOIDANCE | Traveling between Colorado and Missouri, multiple instances of "phantom braking" where, without warning, the car would brake suddenly and very sharply, such that the tires would squeal and items in the back seat slid onto the floor. There were no obstacles, the weather was clear and there was no reason for it to do so. We were only using the cruise control and not the self driving program. Our safety was put at risk because had a car or truck been behind us, a severe rear end collision could have occurred. We were traveling at highway speeds at the time this occurred. We requested a service appointment but Tesla told us this could not be addressed in a service appointment. Tesla said this would be addressed in future updates. We told Tesla this was unsatisfactory and dangerous. We wanted the car inspected and the problem addressed but Tesla said the service appointment could not do anything. There were no warning lamps, messages or other symptoms before the failure. In fact the braking did not even disengage the cruise control, which normally is the case when the brake is applied. This had occurred previously and Tesla said it would be fixed with a computer update in July 2022. Obviously it has not been fixed. | Crash: No Fire: No | Unknown |
| Oct 2022 | FORWARD COLLISION AVOIDANCE | On numerous occasions since I bought the Tesla in March 2021, the car will phantom brake when using cruise control and sometimes on it's own. This happens randomly with no warning and is very dangerous as it risks my car getting rear ended. This is an ongoing problem as you know but Tesla did nothing when I reported it and is still not doing anything. NOT GOOD. | Crash: No Fire: No | Unknown |
| Oct 2022 | SEATS,UNKNOWN OR OTHER,ELECTRICAL SYSTEM | Seat sensor fail and was able to drive in the middle of the intersection to make a left turn. Since the sensor fail if vechicle is driven less the 5 mph the car will go in park- very scary when in the middle trying to turn left | Crash: No Fire: No | Unknown |
| Oct 2022 | ELECTRICAL SYSTEM,SERVICE BRAKES,FORWARD COLLISION AVOIDANCE | Since owning this car in January 2022, there have been issues of phantom braking during cruise control or autopilot. However, today 10/6/22 during an hour and a half time frame my car has had phantom braking episodes at least 5 times in the middle of the highway where it's speed suddenly drops by 20mph. | Crash: No Fire: No | Unknown |
| Oct 2022 | VEHICLE SPEED CONTROL,FORWARD COLLISION AVOIDANCE | Driving with cruise control on following another vehicle 150 yards in front of me. I'm not even using Auto-Pilot because on how dangerous and unpredictable it is. I'm using Normal Cruise Control, which is also a disaster. A car built in 80s can perform cruise control without any hassle. It phantom braked and the vehicle behind me had to take corrective action. This has to be addressed to be fixed. Ditching radar for "vision" was a huge mistake that puts mine and many other lives in danger. A simple cruise control feature that every car is equipped with shouldn't be a death sentence waiting to happen. | Crash: No Fire: No | Unknown |
| Oct 2022 | FORWARD COLLISION AVOIDANCE | We have experienced numerous occasions of phantom braking, or sudden breaking while using the adaptive cruise control. The dealer could not find and mechanical or software problem although the issue persists. This is unsafe because the vehicles breaks suddenly and aggressively from speed without warning and when no breaking action is needed. I fear being rear ended by a following vehicle and have been reluctant to use cruise control. Warnings appear intermittently regarding camera visibility and needing cleaning the cameras have been clear when this warning appeared. | Crash: No Fire: No | Unknown |
| Sep 2022 | VEHICLE SPEED CONTROL,SERVICE BRAKES,FORWARD COLLISION AVOIDANCE | Complaint: Phantom Braking -- My wife and I took ownership of our 2021 Tesla Model 3 at the beginning of July 2021. We experienced what is referred to as Phantom Braking (Car initiating sudden braking while at highway speeds). We took it on a 3,000+ mile road trip to visit national parks in the western United States. Having owned electric vehicles since 2015, we found Tesla's charging network to be reliable and hassle-free to operate. On a few long stretches of road in Nevada, Wyoming, and Utah we engaged model 3's adaptive cruise control. Three times during that trip, between July 2nd and July 8th, 2021, the car braked hard, without warning, while traveling at highway speeds. From what we could determine, shadows cast on the road at the approaching side of gentle hills, with the sun in front of us, may have been interpreted by the car's camera's as an approaching or stationary object on the road. This was very unnerving and caused us to lose faith in the adaptive cruise control system. This was both disappointing and a bother since it meant that we were driving a 50 thousand dollar car without cruise control, making driving a more tiresome experience. This past labor day weekend, 2022, we drove to Las Vegas on the same Tesla model 3 and again activated the adaptive cruise control while driving in Nevada. We thought that by now the periodic software updates would have fixed the problem. This time the Phantom Braking occurred more frequently and on seemingly level sections of road. After about four attempts at using the adaptive cruise control we stopped. This was, again, disappointing that we were driving a car whose adaptive cruise control failed to perform as it was designed to. We were disappointed because for what we paid for the car, this feature should be more mature than it is. Luckily we did not have other cars close behind us at the times the car's computer together with the sensors and / or cameras decided it needed to apply the brakes. | Crash: No Fire: No | Unknown |
| Sep 2022 | UNKNOWN OR OTHER,FORWARD COLLISION AVOIDANCE,LANE DEPARTURE | Tesla allows owners to enroll as FSD beta testers however, the owner cannot unenroll when they request. The FSD beta is extremely dangerous and makes the use of even ACC impossible to use. I have requested to leave the beta via emailing fsdbeta@tesla.com, which an automatic response is received stating to unenroll respond to that email with your VIN and they will process the request. However, they do not process the request; I have sent dozens of email requests with no response and am still stuck in the beta software queue. I have attempted to submit service requests but the app recognizes the verbiage and blocks the submissions, stating to send the email instead. There is no other method to contact Tesla. | Crash: No Fire: No | Unknown |
| Sep 2022 | FORWARD COLLISION AVOIDANCE,LANE DEPARTURE | Pillar cameras constantly complain blocked or blinded. Services refused to even look into the issue blaming glare from the sun, even when happening to both on opposite sides of the car at the same time. Report it even happens at night I am told it might be too dark for the camera. Did not occur like this on my 2019 Tesla Model 3. This seems to be causing random unexpected lane departure alerts or failures in lane keeping on cruise control or with lane assist. Message are extremely frequent and distracting. Message placement is blocked by arm while holding the steering wheel requiring me to take my eyes off the road to read. Been complaining about this for months, one of the two cameras (drivers side) was replaced which improved the issues with that side complaining but passenger side complains extremely often. Drivers side issue not 100% resolved but improved after replacement, possible cabling or MCU/ECU issue. Instead of looking at the issue Tesla insists the cameras must be dirty, moisture, too bright, too dark, etc. And fails to even examine components. Recent appointment canceled by Tesla after the scheduled date and time without notice. Camera doesn't appear to detect or recognize people or objects in that cameras visions creating what appears to be a blind spot when viewing in vehicle display. Have repeatedly seen person walking around my car will disappear from the screen around the passenger front quarter but reappear when in front of the vehicle or by the rear quarter. | Crash: No Fire: No | Unknown |
| Sep 2022 | FORWARD COLLISION AVOIDANCE | Unexplained sudden braking while using adaptive cruise control. Almost got rear-ended as a result. | Crash: No Fire: No | Unknown |
| Sep 2022 | VEHICLE SPEED CONTROL,FORWARD COLLISION AVOIDANCE | Unexpected phantom braking occurring randomly but on multiple occasions during a 2000 mile multi day trip. Several incidents of a hiccup resulting on a jolt but at least three incidents of rapid and sudden deceleration without an observed corresponding hazard. Occurred a couple times while cresting a hill on single and multi lane roads. One severe incident occurred while passing a semi truck on a multiple lane highway. Causes high anxiety and potential for a crash, especially from behind. This has not been inspected by Tesla or others but note many reports of this online. No warning prior to event but cruise control did not work properly after event and required reseting. | Crash: No Fire: No | Unknown |
| Sep 2022 | FORWARD COLLISION AVOIDANCE | Cruise control (Autopilot) phantom braking events have gotten very bad. About once every few miles on an empty 2 lane highway the car slams on the brakes. I’ve made numerous bug reports over the years and if anything it’s gotten worse. It seems to have gotten worse with the software update a few days ago (v11.0 2022.24.6 40a0d11b18af). | Crash: No Fire: No | Unknown |
| Sep 2022 | FORWARD COLLISION AVOIDANCE | I was driving in Oklahoma on a straight interstate highway at 75 mph using cruise control (not autopilot) and experience a sudden application of full brakes. The application was so sudden the tires "chipped" and decelerated to below 45 mph before I could take control by applying throttle. On the same trip, I was near Midland, Texas and experience another serious phantom braking on a clear straight highway. By this time I experienced 10 additional minor braking issues. On my return trip, I did not use cruise control or autopilot and didn't have a single incident. I reported the incident to Tesla Service and reported ever incident via the feedback button (when it worked). I'm a retired Boeing engineer experienced in flight controls, fly-by-wire control, and aircraft subsystem design. I have no confidence in this design. | Crash: No Fire: No | Unknown |
| Sep 2022 | FORWARD COLLISION AVOIDANCE | On an empty freeway I5 southbound over a crest, the car emergency braked from highway speed with no obstacles or cars in front of it. The weather conditions were sunny, 98f, and some mirages were on the road surface. Autopilot was engaged and set to the speed limit. Emergency braking alert sounded and the car applied full power braking. Car is running software version 2022.24.6. prior versions of the software with radar support did not exhibit this phantom breaking behavior. The current version disabled radar and used "Tesla vision" | Crash: No Fire: No | Unknown |
| Sep 2022 | STEERING | The steering system malfunctioned. Yes it is available for inspection. The car turned across oncoming traffic turning the vehicle 180 degrees leaving me facing oncoming traffic during rush hour. I could have died in a horrific accident. The service center for the vehicle sulfate they will not evaluate vehicle until body damage to vehicle are repaired. The vehicle had no notifications or warnings prior to the incident. | Crash: Yes Fire: No Towed | Unknown |
| Sep 2022 | FORWARD COLLISION AVOIDANCE | Was driving about 35-40mph on city street when car abruptly applied emergency braking. Car automatically slammed on brakes (screeching) and came to complete stop. This action was dangerous because it could have caused an accident if another car was behind me. Caused fear and panic as I believed something or someone had hit my vehicle, it also scared a pedestrian that was walking along the sidewalk. The sudden braking also caused my body to violently jerk forward and backwards. This has not been reproduced or confirmed by dealership or service center. It has not yet been inspected by anyone. I have made an appointment for car to get inspected, appointment is 9/16. No warning lights or symptoms came on prior to this incident. | Crash: No Fire: No | Unknown |
| Sep 2022 | SERVICE BRAKES,FORWARD COLLISION AVOIDANCE | While using my Tesla's Full Self Driving (FSD) feature (Navigate on Autopilot) on a recent road trip through West Texas, the vehicle, on multiple occasions, would automatically brake while cruising at speeds of 80 mph (speed limit was 75 mph), which consequently dropped the vehicle's speed over 20 mph within seconds. The result was being forcibly slammed forward with such a jarring, unexpected force that would have easily slammed me as the driver and my front seat passenger into the wind shield if we were not wearing our seatbelts. This happened multiple times on the trip. The only way to recover was to depress the accelerator and forcefully hold on to the steering wheel until the braking system released and control was returned to the driver. If this had occurred on a crowded highway rather than on the open spaces of the West Texas interstate system, I am convinced there would have been a rear impact collision. This "phantom breaking" as Tesla claims, is a serious issue that will no doubt lead to fatalities if not corrected. This issue manifested without warning and with no alerting. The issue can be easily reproduced and the component has yet to be inspected by any 3rd party. I fear people will die because of this issue until it is resolved. Thanks, Sean Merino | Crash: No Fire: No | Unknown |
| Sep 2022 | POWER TRAIN,VEHICLE SPEED CONTROL,FORWARD COLLISION AVOIDANCE | The adaptive cruise control (Tesla "autopilot") system has unexpectedly disengaged and applied light to heavy braking numerous times. The system frequently mistakes a particular highway sign for a stopped vehicle and applies moderate braking. The system has also applied light to heavy braking in circumstances where I simply cannot figure out what the camera is interpreting as a hazard. This puts me and other drivers around me at risk as it is unnecessary and unpredictable braking at highway speeds in traffic. Tesla has not been able to remedy this problem and I do not consider the cruise control system to be safe to use. This has happened more than 10 times. | Crash: No Fire: No | Unknown |
