| Jan 2023 | FORWARD COLLISION AVOIDANCE | Trip from Piedmont, California to Salt Lake City, Utah, I experienced three (x3) phantom breaking incidents at over 80 mph on interstate 1-80. The car without warning dramatically de-accelerated from approximately 85mph to 65mph or 60mph without warning and suddenly. Dog was riding in back and thrown into front dashboard on one occasion. Visited Tesla dealership on State St in Salt Lake City Utah upon destination arrival and manager/head at front desk laughed indicents off saying, "we've heard of such incidents just wait for the software update." Horrible. Beyond dangerous. I can report that in all three incidents there were no cars in front or behind me and the phenonenon occurred totally unexpectedly. Reported it also to Tesla repair shop in Berkeley, California, and intake group had zero sympathy and said, "it's a known software glitch." | Crash: No Fire: No Injuries: 1 | Unknown |
| Jan 2023 | FORWARD COLLISION AVOIDANCE | On multiple occasions, the car will suddenly decelerate while using adaptive cruise control on the highway. Malfunctioning component: adaptive cruise control. Safety: rear end collision if another vehicle was following too closely. Manufacturer is fully aware of the problem. | Crash: No Fire: No | Unknown |
| Jan 2023 | SUSPENSION | The wheel control arm bolts that hold the wheel onto the vehicle slowly unscrewed until they fell out (x2 bolts per wheel). It is available for inspection upon request. If a disconnected fully inflated tire is sucked under the car at high speeds, it may potentially flip the vehicle, badly rupture the battery pack or the wheel may jettison from the vehicle onto surrounding vehicles. It is unknown what kind of damage or after-effect would take place if the battery were severely damaged by an inflated tire and rim. The problem was observed, documented and repaired by Tesla. The effects of the problem were only observed at 1 MPH. A recall of this specific issue was listed for other Model 3 2021 vehicles, but our vin # was not included in this recall, while it should have been. Tesla has inspected the vehicle one time and claim the vehicle is now safe to drive. Insurance would not participate in any claims regarding this type of incident because nobody was hurt. We did not receive any warning prior to failure, not even a wobble, shimmy, clunk or precursor of any kind. The car appeared to be perfectly solid and then suddenly the wheel came off. The car did not crash into anything other than the ground when the wheel disconnected. | Crash: No Fire: No Towed | Unknown |
| Jan 2023 | VEHICLE SPEED CONTROL,FORWARD COLLISION AVOIDANCE | I was going 80mph on the interstate coming back from Little Rock to Tulsa. The time was 4am in the morning with little or no traffic on the road. I was using only the cruise control with adaption turned on. The car all of a sudden without any warning almost came to a complete stop on the interstate. I later asked what caused this and was told it is phatom braking but this was VERY dangerous, if someone had been behind me they probably would have been messed up. I merely accelerated to make sure I was at least keeping the minimum speed limit. Please advise. Shawn | Crash: No Fire: No | Unknown |
| Dec 2022 | ELECTRICAL SYSTEM,VISIBILITY/WIPER | The supermanifold failed, causing the front defroster to not work properly, resulting in loss of visibility in freezing temperatures. This is a common problem with 2021/2022 model 3/model y with the new heat pump that was supposed to be fixed with a software update, but was not. I now have a $3900 repair bill on a 1 year old car with 56,000 miles. The warranty expired at 50,000 miles. The failure was not a result of negligence. | Crash: No Fire: No | Unknown |
| Dec 2022 | FORWARD COLLISION AVOIDANCE | Adding our vehicle to the list of those affected by what seems to be commonly known as "Phantom Braking". The most recent occurrence was on Interstate 25 southbound in northern Colorado when the "Autopilot" (Adaptive Cruise Control) suddenly braked and reduced our speed from 75 to 51 mph, with no vehicles or other obstructions visible. We were almost rear-ended by a car following us, however. I want to point out that this was only the worst example of several episodes that occurred that day, and on earlier dates as well. We no longer use Autopilot, which makes long trips much less comfortable. I also want to mention that our vehicle does NOT have Tesla's "Full Self Driving" (FSD) installed, so my hands were on the wheel at all times. | Crash: No Fire: No | Unknown |
| Dec 2022 | STEERING,VEHICLE SPEED CONTROL,FORWARD COLLISION AVOIDANCE | On certain sections of highway unsuccessfully attempted to activate auto-steer (two down clicks) multiple times in a row. Did this multiple times in a row but was unsuccessful to activate auto-steer. Instead a supposed "easter egg" (which activates with 4 down clicks) very loudly plays loud jarring music (called "rainbow road")...this is NOT FUCKING FUNNY--I nearly ran my car off the road and into oncoming traffic. Giant 2000 pound hunks of metal going at 60 mph should NOT FUCKING COME with special surprises. This is incredibly dangerous and jarring to drivers. | Crash: No Fire: No | Unknown |
| Dec 2022 | ELECTRICAL SYSTEM,FORWARD COLLISION AVOIDANCE | The contact owns a 2021 Tesla Model 3. The contact received notification of NHTSA Campaign Number: 22V235000 (Electrical System, Forward Collison Avoidance) however, the part to do the recall repair was not yet available. The local dealer was contacted. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was made aware of the issue. Parts distribution disconnect. | Crash: No Fire: No | Unknown |
| Dec 2022 | ENGINE AND ENGINE COOLING | Driving south on the 5 freeway right northing on Oceanside the vehicle shut down at freeway speed. I had to coast of the to the first Oceanside. Fortunately it was late at night and there were no cars in the immediate vicinity. In addition to this the vehicle has had multiple episode of phantom breaking. I do not feel safe driving the car. | Crash: No Fire: No | Unknown |
| Dec 2022 | SUSPENSION,STRUCTURE,FORWARD COLLISION AVOIDANCE | Random "phantom braking" while using autopilot or cruise control. Causes the car to slam on brakes and has lost control once almost causing me to go off the road. Also, has brake-checked many cars that follow behind me while I'm using autopilot or cruise due to the phantom braking. Also Tesla Repair center in Chicago replaced my front bumper with a discolored front bumper that had the same issue of peeling on the inner edges of the bumper as the prior front bumper. When I brought up the issue to Tesla they said that was a manufacturing process issue due to the molding process of the bumpers and that is how they all are. If that is the case why change the bumper? Could have just told me that's how all the cars are and saved a lot of my time. Also, have had many repairs from Tesla that don't seem to end. These cars arent being produced in a consistent manner. What was promised during the purchase of the car doesn't seem to hold up. | Crash: No Fire: No | Unknown |
| Dec 2022 | UNKNOWN OR OTHER | At some point in 2021 Tesla released a software update that causes the vehicle to ignore the ambient temperature sensor for the first 15 minutes of a drive. Tesla explained to me that this was to avoid errant readings in hot environments with lots of reflected heat from pavement. I’ve reported the following safety issue to them several times through the winters of 2021 and now 2022, to no avail despite numerous software updates since. In cold environments where a vehicle is leaving a warm and potentially higher humidity environment such as a garage to a very cold and dry environment - just as the car begins using the sensor data the windshield will immediately fog up causing a major safety issue. This occurs with the hvac on auto and requires a shift of 30+ degrees, which is not an uncommon occurrence in cold environments. 50 degree garage to 17 degree outside for example. | Crash: No Fire: No | Unknown |
| Dec 2022 | FORWARD COLLISION AVOIDANCE | The contact owns a 2021 Tesla Model 3. The contact stated that while driving at various speeds, the vehicle experienced phantom braking. The contact stated that the adaptive cruise control was activated during the failure. The failure recurred several times. The vehicle had not been taken to the dealer to be diagnosed or repaired. The manufacturer was not made aware of the failure. The approximate failure mileage was 14,169. | Crash: No Fire: No | 14,169 |
| Dec 2022 | ELECTRICAL SYSTEM | The contact owns a 2021 Tesla Model 3. The contact stated while driving 20 MPH, the vehicle inadvertently made a sudden stop and then lost motive power. There was no warning light illuminated. The contact attempted to restart the vehicle; however, the vehicle failed to restart. The vehicle was towed to the dealer, and the contact was informed that the inverter failed and needed to be replaced. The vehicle was repaired. The manufacturer was not contacted. The failure mileage was 9,000. | Crash: No Fire: No Towed | 9,000 |
| Dec 2022 | LANE DEPARTURE | I believe that Tesla's autosteer and Full self driving features are improperly designed. I will speak to them as if they were one and the same. I noticed that you have a check box for Lane Keeping Assistance above, but there is no checkbox for coercive auto steering, which is Tesla's product. The only ability it offers as far as steering the car is to forcibly disengage the autosteering feature. This is not assistance and this is the problem. A properly designed Lane Keeping Assistance feature continuously monitors driver steering action, lane position, and traffic conditions. If the Lane Keeping Assistance system finds itself 'alone' with little or no measurable input from the driver, action is called for. With the Tesla, the feature has an embarrassingly stupid 'driver attention check' which, until recently, could be easily defeated by the simple addition of a weight to one side of the steering wheel or the other. In a misguided attempt to correct this ridiculously poor design, they have recently made matters much worse. Now they distract the driver's attention from driving by forcing the playing of some sort of 'patty cake' type game, which does prove alertness of the driver, but detracts from the real and necessary work of circumventing the actual threats encountered in everyday driving. In short, a proper Lane Keeping Assistance feature should not be totally ignorant of the driver's subtle driving moves (it's an excellent feature as long as autosteering isn't engaged) and should honor requests to move into different parts of the lane long before disengaging, and no attention measuring system should come at the expense of driver awareness of actual issues. I have tried through email and phone to convince Tesla that something needs to be done, but have received no response from them. | Crash: No Fire: No | Unknown |
| Dec 2022 | ELECTRICAL SYSTEM | The contact leased a 2021 Tesla Model 3. The contact stated upon starting the vehicle, the center display failed to operate as designed. The contact was able to drive the vehicle; however, while driving 25 MPH, the vehicle stopped abruptly in the middle of the road. A message indicating that the trunk was opened was displayed. There was also a question displayed whether the contact wished to continue driving. The contact tapped the option YES however, the touch pad center display failed to respond. The contact exited the vehicle and attempted to close the trunk several times; however, the trunk reopened independently. The contact was able to close the trunk after eight attempts. The contact was able to continue driving to her residence. The contact stated that upon parking the vehicle, the trunk reopened independently. The manufacturer was notified of the failure and assisted the contact with towing the vehicle to the local Tesla Service Center where it was diagnosed that an unknown software had failed. The vehicle was not repaired. The manufacturer declined to provide additional information. The failure mileage was approximately 15,460. | Crash: No Fire: No Towed | 15,460 |
| Dec 2022 | ELECTRICAL SYSTEM | The cabin heater stopped working. I received an error code "VCFRONT_a447" recommending to take the vehicle in for service. This issue is a problem in sub-zero climates where the windshield will not defrost before and during driving. I have found 67 other cases from reddit and tesla motors club describing the same issue, on new or <2 years old cars. My components have not been inspected. I tried a full hard reboot of the software and no fix. Tesla service estimates $1,792 repair. Replacing a Supermanifold ($450.37) & A/C compressor ($1273.53) +tax =$1792. I am out of warranty by milage, car is 1.5 years old. 60,200 miles. | Crash: No Fire: No | Unknown |
| Dec 2022 | ELECTRICAL SYSTEM,VISIBILITY/WIPER | I'm getting a notification that says " cabin climate control system requires service cabin heating/cooling limited or unavailable". As a result of this failure the defroster is not working properly. The windshield defroster will only blow cold air very slowly. This causes the windshield to fog up very quickly in cold temperatures. I cannot see out of the windshield properly. | Crash: No Fire: No | Unknown |
| Nov 2022 | VISIBILITY | The contact owns a 2021 Tesla Model 3. The contact received notification of NHTSA Campaign Number: 22V702000 (Visibility) however, the part to do the recall repair was not yet available. The local dealer was not contacted. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was not made aware of the issue. The contact had not experienced a failure. Parts distribution disconnect. | Crash: No Fire: No | Unknown |
| Nov 2022 | SERVICE BRAKES,FORWARD COLLISION AVOIDANCE | While using cruise control on a cross country drive, there have been numerous instances of phantom braking in my Tesla Model 3 SR+ (2021). This has been occurring during both day and night driving on the highway, at speeds of 65-75mph. It appears to happen most frequently when there’s a slight up-hill on the highway followed by a slight downhill and then phantom brake, but there have been instances on flat highway road at night with phantom braking taking place. | Crash: No Fire: No | Unknown |
| Nov 2022 | ELECTRICAL SYSTEM,UNKNOWN OR OTHER | It has been weeks and Tesla has still not provided a fix for this issue. It was supposed to be resolved over the air but we have called Tesla for weeks and they have no idea when the fix will be available. Do they have a time limit to resolve? Sep 19,2022 Manufacturer Recall NumberTBD NHTSA Recall Number22V702 Recall StatusRecall Incomplete | Crash: No Fire: No | Unknown |
| Nov 2022 | SERVICE BRAKES,FORWARD COLLISION AVOIDANCE | I have had the car for about 1.5 years. In the last week it has started to have phantom braking where on a clear, flat road with no traffic, it suddenly has hard braking and slows from about 65 mph down to 40-50 mph. This has occurred when operating on Autopilot with the cruise control and autosteer on. There is a risk of a rear collision with this sudden braking. There was no warning. I do not have Full Self Driving. | Crash: No Fire: No | Unknown |
| Nov 2022 | FORWARD COLLISION AVOIDANCE | Model 3 sudden Max speed reduction (60/55 to 25/30) when using Autopilot. This happens every time and in multiple areas when driving on I-4 through Orlando, FL. | Crash: No Fire: No | Unknown |
| Nov 2022 | SERVICE BRAKES,FORWARD COLLISION AVOIDANCE | Driving in empty highway, no cars in front of me for great distances, on cruise control, the car would all of sudden perform hard braking. It happened many times in the course of two 6 hour drives over a weekend and I couldn't figure out what scenarios were predisposing to this. I also tried out autosteer (not autopilot) and it did it in autosteer too. It was very hard braking, not just disengaging, and so I just drove without cruise control because it is too dangerous and risks getting rear-ended because I am braking without warning and for no reason. | Crash: No Fire: No | Unknown |
| Nov 2022 | EXTERIOR LIGHTING,FORWARD COLLISION AVOIDANCE | The Tesla uses “auto high beam” when in autopilot. The pros of this can allow drivers to utilize the light so the cameras can detect anything to avoid any possible wrecks, but it does not have an option to be turned off. Along with other people online, my brights have flashed at people on the interstate and highways or haven’t turned off at all. This is irritating and limits the way I am comfortable with using autopilot. Please inform Tesla to make the auto high beam feature OPTIONAL. | Crash: No Fire: No | Unknown |
| Nov 2022 | FORWARD COLLISION AVOIDANCE | I was on a road trip on rural highways in Texas and New Mexico. The adaptive cruise control/autopilot system repeatedly hit the brakes when driving at highway speeds for no apparent reason. This would happen even though there were no cars in front of me or other obstructions in the roadway. If there had been another car behind me there would have been risk of a rear end collision because the car would unexpectedly significantly reduce speed. A few times when this happened, the car made warning sounds, but most of the time it would not provide any warning at all. I have tried making a service request with the manufacturer, but they claim that there are no hardware problems with the car and I have to wait for a firmware update. | Crash: No Fire: No | Unknown |
