2018 Tesla Model 3 complaints

A portion of the Power Conversion System "PCS" has failed in my 2018 Tesla Model 3 extended range with 34,000 miles, resulting in the inability to charge the vehicle but at 32 of 48 capable amps. Reports from other Tesla owners indicate that remaining portions of the PCS can fail resulting in charge amperage reduction to 16 amps or inability to AC charge completely if all portions of the PCS fail. This issue is apparently not an isolated incident. The PCS in this vehicle appears to be flawed due to reports of early failure and the number of reported failures. The issue goes beyond the previously released service bulletin of 2018 Tesla Model 3s manufactured between June and July 2018. Tesla will not cover the cost for the repair, either in good faith or under the battery and drive unit warranty. The repair is costly, but left unrepaired the car may not be capable to charging using level 1 or 2 charging if the PCS fails completely. The error for this issue is seemingly difficult to find. It is not indicated on the Tesla app. It is only discoverable when in the car, while the car is charging and when trying to charge at or above 33 amps. Unlike a traditional check engine light, the error goes away and because the car still charges, it is difficult to realize an issue exists. I'm unaware of when the error first occurred because of this. It is likely the error existed before the general warranty for the car had expired. It doesn't appear Tesla does a diagnostics scan for this erro

Phantom braking is extremely dangerous and a cause for disaster! While in Autopilot, it will unexpectedly brake while driving on the freeway. This causes a jerk to the human body and cause a possible rear end accident. This is quite frequent.

Newer software disables existing radar in the car; this "Tesla Vision" is objectively worse at providing automatic braking response correctly, often scared literally of it's own shadown Newer cars don't even include the rdar, an ill-advised cost saving initiated by Tesla

Regularly when autopilot or cruise control are engaged, the emergency braking will abruptly slow the vehicle when no object is on the road, highway, or interstate. This creates an unsafe environment when vehicles behind you are not following at a safe distance. We have had several instances a month where the vehicle will slow from 75 to 30 in a few seconds and require human intervention to speed up. This issue has been ongoing since we received the vehicle almost 30,000 miles ago.

Driving down the freeway with Autopilot engaged and the autopilot started hard braking in the middle of the road going 70mph. No accidents occurred but it was a very dangerous situation

I've heard a loud crack while driving, in a curve. The car felt strange when steering, with noises and strange feeling while driving. I was close to home, so decided to just as park and notify Tesla. While I was parking, I've noticed the wheel touched the car on a sharp curve. I've decided to no longer drive it, scheduled a Tesla service center appointment (3 weeks later). We didn't drive the car any longer. On the day of service, I've called a tow truck. As the tow driver was pulling my car into the tow, a large bolt felt from under my car; and steering at this point was impossible (tire would touch the car). The service center replaced both sides LATERAL LINK and bolts. I've looked up this part, and found the recall 21V83500, SB-21-31-003 - which stated a situation very close to mine. My car was 2018, which was out of the recall range; but it is very likely the same issue.

While driving my vehicle, no matter if I am on the interstate, country roads, side roads the vehicle will brake for unknown reasons. It will go from 65mph to 35mph, or 55mph to 45mph, etc. This happens whether in cruise control, auto drive or manual drive. It also will brake behind trash trucks with their flashing lights on, intersection flashing lights or warning flashing lights on the side of the road. It has also done it at night with oncoming vehicles. This is a daily occurrence. I have contacted Tesla service center on a few occasions and I am always told it is a computer issue, there is nothing that can be done. This is an extreme SAFETY issue and can cause a rear-end accident or another type of accident. I can not believe this issue has been going on for years and Tesla can not come up with a solution.

Vehicle developed a loud squeak coming from driver’s side front wheel well that sounded like a something vibrating or rubbing a spring at ~54300 miles. Reported issue to Tesla via the Tesla app. Tesla’s recommended solution is to replace both the right and left Upper Control Arm. Further research found that this is a widespread problem reported by Tesla owners on the web. Indeed when I was at the Tesla Service Center the women in line in front of me was bring in her vehicle for the same problem. The upper control arms include a ball joint that needs to be lubricated. This vehicle’s upper control arms DO NOT have a built in means to lubricate that joint like a Zerk fitting. The vehicle is available for inspection. The safety issue here is a defective and/or poorly designed part which if left un-lubricated would likely experience water intrusion, corrosion and possible catastrophic failure – maybe breaking at speed. Our vehicle has lost lubricant at the ball joint given the noise and is likely susceptible to/experiencing water intrusion. Also found “SB-20-31-006 Service Bulletin Reseal Front Upper Control Arm Ball Joints”, but this curiously does not include our vehicles VIN. My suspicion is our Upper Control Arm has a different part number than the Upper Control Arm in SB-20-31-006 but is likely a very similar part. My concern is part number whack-a-mole is taking place. Tesla did not even have to inspect the car to know what the problem was. No other parties have inspected th

The contact owns a 2018 Tesla Model 3. The contact stated that while reversing, the Back Over Prevention camera became inoperable nearly causing the vehicle to crash into the garage. The dealer and the manufacturer were contacted and stated that the contact had to pay for the diagnostic test even if the VIN was included in NHTSA Campaign Number: 21V00D000 (Electrical System, Visibility, Back Over Prevention. The failure mileage was 90,000.

In 2021 the vehicle reported – “Front passenger safety restraint system fault/Contact Tesla Service”. Tesla performed OCS rework installing an Occupant Classification System (OCS) Filter Module (part SERVICE KIT – OCS REWORK (1479982-00-C)). In 2022 the vehicle reported “RCM_a056 Front passenger safety restraint system fault service required”. Tesla’s proposed correction is to replace seat (part 1ST ROW SEAT ASSEMBLY – RIGHT HAND – PUR BLACK (7654324-91-C)). The safety risk may be serious and alert RCM_a056 is being reported by other owners on the web so the problem is not isolated. My understanding is the Occupant Classification System (OCS) Filter Module is part of the airbag system and weighs occupants in the front seat. The OCS Filter is used to determine if the front seat is occupied and possibly classify occupants by weight to determine if and/or by how much airbags should be deployed. The safety of a person in the front passenger seat maybe at risk because of this faulty OCS which could result in airbags failing or deploying dangerously based on erroneous OCS inputs. The problem was identified by two faults reported by the vehicle, the first OCS failure was confirmed by a Tesla Mobile Technician and the component was replaced (part SERVICE KIT – OCS REWORK (1479982-00-C)). The Tech said the seat heater was causing interference with the OCS’s unshielded wires. The second fault the vehicle reported was also confirmed by a Mobile Service Technician who said the replacemen

The car has had numerous ball joints fail over its service life. None were covered under warranty (at least the first set should have been). Tesla doesn't consider this safety critical, and for the latest round, made me wait over a month for parts to arrive. I don't know how severe the problem actually is and whether its dangerous or not, but they never even bothered to inspect it. This is clearly a design flaw since these keep failing, and the control arms have to be replaced as well since its apparently one assembly.

The horn has failed. It started failing around 40,000 miles, and has completely died now at 147000. I am aware of many other horns that have died on MY 2018 vehicles, and apparently they don't consider it a big deal. They're replacing it (which I have to pay for), and apparently they charge everyone for it. If these really are failing like crazy, these should be a safety recall.

2018 Tesla Model 3 LR RWD with approximately 56,000 miles. A loud squeaking/creaking noise started on front driver side when turning at low speeds. This progressed to higher speeds. I inspected the car and found that the noise is coming from the upper control arm ball joint. It seems this is a common issue for this vehicle according to online research. This is a potential safety issue as this seems to be a premature failure of the part. Basic vehicle warranty recently ended. Tesla plans on replacing the upper control arm and charging me full price for parts and labor.

This defect is regarding Tesla’s FSD (beta). In the FSD mode, the car switched lanes without noticing the presence of a vehicle in the destination lane and caused a non-fatal accident. I was driving on O’Shaughnessy blvd in San Francisco around 8:50 AM. The weather was clear, and traffic was moderate. I had turned on FSD and entered my destination address. I stayed below the posted speed limit as I was new to FSD and wanted to stay extra alert. At this point, O’Shaughnessy is a single lane on each side. The lane gets wider as it nears a major intersection (Portola Drive). And then it splits into two lanes. Finally, the right lane becomes the right-turn-only lane. Per the route, the car was supposed to take a right turn at the intersection. When the lane split into two, the vehicle remained on the left for about 30 feet. Then it rapidly began to shift to the right lane by giving a signal. However, the vehicle behind me had moved into the right lane by this time. My car did not notice the vehicle as it tried to move to the right lane. It hit the other vehicle. This shift to the right lane was so rapid that I could not react to the impending collision fast enough. The other vehicle’s left-hand front fender hit my passenger door. Even as the vehicle collided, Tesla’s advanced driver assistance system failed to notice the presence of the other car. It did not give an alarm. My Tesla had all available safety warning options on. Since there was no injury, we did not file a police co

The ball joint and control arms in the front start squeaking just after warranty ends at 50k miles. Eventually this could lead to it locking up and causing an accident. This needs to be a covered recall, since all 2018 tesla model 3 cars experience this. When researching I found out how much of a problem this is and itvwill cost over 1000 dollars to fix.

I was driving in rain with lane keeping assistance enabled. As the car followed a curve, my tires began to hydroplane and the front end began to lose directional control and drift to the right of my direction of motion. I overrode assisted steering and attempted to keep the front end aligned with the rear so as to avoid a spin. At this moment, I felt the adaptive cruise control add torque to the rear wheels which pushed the rear tires out from behind and aggravating the planing, and defeating my effort to keep the car aligned. I suppose I then fully disabled the cruise control, but the car had already rotated too far to recover directional control, and it spun 180 degrees (front wheels trailing the rear wheels.) This continued briefly until turning tail first up an earth embankment before coming to rest. There were no cars immediately near me at the time or it might have resulted in a multi-car collision in a hydroplane zone, with a good chance of multiple serious injuries. The vehicle was inspected by the insurance adjuster and repaired. The car is available to examine. There were no indications of a system failure and Tesla did not concede to any. I contacted Tesla service and requested to examine the control system data to assess if the adaptive cruise control had contributed to the loss of control. After providing a Tesla agent with the time of the event he asked for, he reached back to me and stated that they were able to archive the data from the time of the accident. H

With NO WARNING, and while on AutoPilot-Full Self Drive, our Tesla TOTALLY HARD AND LONG BRAKED out of nowhere, THRUSTING our necks forward for four seconds until I could disengage the brake, then SLAMMING our heads to the headrest. I have a CERVICAL SPRAIN, WHIPLASH, and a CONCUSSION! I was driving 65mph. I’ve been to the ER, to a chiropractor, and to physical therapy since this incident Sunday, July 31, 2022 at 6:37-6:38pm. On the 405 South. I’ve reported it to Tesla Service who said it was escalated to the Fremont location Engineers to review which takes 2-3 months! I have INJURIES! Phantom braking is usually unwarranted and terrifying but has not HURT ME until this time. I was almost HIT by the car behind us!

The rear back up camera on my vehicle is experiencing intermittent delays in showing a picture. Although there is an open recall on my vehicle that was issued back in December of 2021, Tesla has still not contacted me to advise when my vehicle can be brought into compliance with the recall. When I proactively contacted them earlier today, they stated that they still do not have the part(s) necessary to complete the recall. It seems odd that a vehicle manufacturer can fail--for approximately 8 months and counting--to address an open NHTSA recall without any communication to customers (or their regulator) as to when, exactly, they expect to remedy the issue.

Phantom braking that causes the vehicle to suddenly apply the brakes for no reason. Issue occurs at least once each time I use the Autopilot. Occurs on interstates as well as highways. In my 6 hour drive today it happened 5 times. Each time the vehicle decreases in speed by 15-30mph. This is extremely dangerous for vehicles following behind and for the passengers who are suddenly jolted.

I have the issue recorded on video. The computer display totally froze for several minutes while driving on the highway. The turn signals would not work while the computer was frozen and the system needed to reboot after several minutes before the turn signals would start working again. I was in autopilot at the time of this happening. Video documentation can be provided. Here is a link to the video of the safety issue on Google Photos: https://photos.google.com/share/AF1QipMUiX6JR5ppOGGqTCRlWxH1Hiv7hLr2Gm9G5wjjIfYFKz4-Lg7D-_nfAzTTalFX3Q?key=anRJQWo3TGNiM0F1cEJOczZOZ3RTRnRQMm1WOFpB

The contact owns a 2018 Tesla Model 3. The contact received notification of NHTSA Campaign Number: 21V00D000 (Electrical System, Visibility, Back Over Prevention) however, the part to do the recall repair was not yet available. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The dealer was not made aware of the issue. The manufacturer was made aware of the issue. The contact had not experienced a failure. Parts distribution disconnect.

I have noticed unwarranted braking while using cruise control. I have been able to confirm at least some of it is due reconstruction of the highway. At certain places the car thinks I am on an exit ramp with a 45mph limit when I am actually on the main highway. It then suddenly slows the car until I correct it using the accelerator.

After purchasing the Autopilot feature on February 9th, 2022, on our first trip next day (Feb 10th), we experienced phantom braking with adaptive cruise control turned on, barely avoiding a hit from the rear by a truck in Toledo, OH. Later, during same trip, we experienced phantom braking with both ACC and Autopilot features turned on, and stopped using them out of safety concerns. After a new occurrence, while on cruise control on June 4th, I informed Tesla service in Clarkston, MI, but no repair, deletion of Autopilot and reimbursement was possible as I requested. We never had similar issues form November 2nd 2018 to February 9th 2022 (44.159 miles) , before purchasing and installing Autopilot.

Constant phantom breaking while using cruise control, autopilot or FSD. A reoccurring problem that happens more and more often.

My Tesla 3 suddenly braked while driving on the road from about 40 mph to 10 mph. There was nothing obstructing my car from the front or sides. It was a scary experience. My neck was jolted forward and the seatbelt pressed very tightly against my chest. I immediately scheduled for service with Tesla. I then got a call from them and was told I should be okay to drive my car until my scheduled appointment a week from now! How is this not an emergency?!

The car brakes by it and accelerates by it. Some time it says I am not holding the steering wheel and it cancels the autopilot in the middle of the long distance driving. The defective cabin camera does not see the hand position at all and randomly keeps on distracting from the front road view to the screen which is not in the same line as the road. Too many errors of auto pilot are very frustrating and distracting. The Tesla’s team tries to repair something and keeps on blaming their own departments not to fix things correctly. I have tried many times to make an appointment thru their app which is very buggy and it’s like one way communication. I have multiple recalls on my car but they don’t have time or parts to fix it. They will not allow making any weekend or within 20 mile radius service center. Once they do any repair their technician drops the ball and do not want to fix the original problem correctly. The full self driving is ridiculous I have not been able to complete even 10 miles trip without taking over in few minutes. This FSD software/hardware needs to be more accurate as soon as possible so that there is no harm done to the driver and passenger to the Tesla and other cars.

When the vehicle's directional is activated, the side camera on the activated side of the directional is activated and displays the blindspot area on the car's center screen. I.e. you want to change lanes and you activate the left directional to signal moving into the left lane, the left side camera activates and displays on the screen what is in the left lane. This is a very handy feature, unfortunately at night the "blinking" of the directional completely blinds the camera. It also completely saturates the center screen with a orange/red light when the directional is blinking. Tesla has fixed this problem with newer vehicles, they have an updated side camera that has a partition in the camera to block the light coming from the directional. Tesla will not replace the earlier side cameras. I was advised by Tesla service to shut off the camera at night. I find this solution to be completely unacceptable as I am accustomed to using the blind spot feature. This is a software/hardware incompatibility/defect and I believe there should be a recall in regards to this issue.

1) Ongoing issue with car braking suddenly when no other cars are ahead of it. 2) When in auto-pilot, the car brakes late when carrying speed. This has happened when the car is less than 1 car length behind the car ahead of it forcing me to disengage and brake hard to avoid a collision. In one incident, I had to swerve the car and drive onto shoulder of the highway to avoid a collision. 3) On 7-16 the the undercarriage cover detached from car while driving on highway.

Tesla no longer automatically turns on headlights when the automatic wipers are enabled, this used to be a functionality of the vehicle. The ability to turn on headlights is extremely difficult and requires going through multiple screens while driving, something that is extremely dangerous. Tesla also does not allow you to turn on headlights with voice command. Proposed Fixes #1) Restore functionality that turns on headlights when wipers are enabled #2) Same as #1, but as a preference setting that requires a driver to enable that setting #3) Allow a driver to turn on headlights via voice command. If there is a safety concern that the voice system may turn OFF headlights, disable the ability to turn OFF but enable the ability to turn ON. Long story short the vehicle needs to automatically turn on the headlights when the wipers are on.

There was a recall for the Model 3 trunk harness on Dec 21, 2021. Manufacturer Recall Number: TBD NHTSA Recall Number: 21V-00D Recall Status: Recall Incomplete I attempted to schedule a service appointment with Tesla to remedy this situation but they rejected my appointment. It has been more than 6 months and they still have not reached out on fixing this recall.

Since I purchased this car new in Sept 2018, the car has had a "front Left safety restraint system fault". It has been fixed over 3 times and it is going for the 4th time now. The car is going out of warranty this year and I am afraid I will be stuck with the bill if it happens again. Even though all the fixes have been free so far, it is an ongoing problem Also, the known phantom breaking, just add to the numbers. it is more than common. I almost see it coming when going under overpasses because of the shadow. The computer must see it as an object. I have inquired about the lane departure warning and they keep saying it is just a software issue. If it is activated at any point during the drive, then it says that "lane departure warning" is not long available and may be restored on the next drive.

Intermittently, the main screen that has the map will go haywire, making navigation with the map impossible and putting safety at risk. Even after rebooting the computer (while driving), the issue can persist, making it very difficult to know what speed I'm going due to the issue as it is very distracting. I have video of the latest incident available.

Ghost braking hard and want refunded for full self driving because it’s not there

This car was hit in a T bone on March 15th 2022 by a Toyota RAV4 on the driver side , the driver side was completely smashed and the car spun 2 times and came in the middle ramp. In spite of this heavy impact there were no airbags deployed , after several follow ups with Tesla I have no answer so far. The car was deemed total loss last month and even after consistent follow ups I have no answer from. Tesla. The impact was very heavy that my wife had whiplash and she went through chiropractic treatment for 2 months .. I’m very worried as the impact was so bad that this is a fatal flaw in Tesla and they do not have the airbag curtain deploy to protect the driver side at all - my wife was lucky and she is alive but this could happen to anyone .. I need an answer from Tesla and I found I could get it through this website and need the right measures take so that no one will get injured or cause life in any accident in future

Driving today on I45 between Dallas and Houston on beta autopilot I was traveling at the speed limit of 75 with much room to the next car, maybe 1/2 mile the car suddenly did a panic breaking for no reason. I took control by the time it was at about 30 mph and got back up.to speed but I'm positive the car behind me was alarmed. No damage or incident but it was quite alarming.

Driver Side Supplemental Restraint system reported an issue and need for service. Service department blames faulty electrical harness under the seat. A search of the web shows this is a common failure, leading me to believe that it is a design or a quality control issue. Tesla declines to repair under warranty because warranty expired 610 miles prior to notification.

Autopilot failed and crashed into another car while changing lane didn't detect coming in left lane and tried to changed and crashed into it. It put everyone in the car in life threatening risk

Every time we have it on autopilot on the tollway, we experience phantom braking at the same location regardless if we are going south or north. It is dangerous if there is a car behind us.

Going down an undivided single lane each way roadway at 55 MPH car suddenly hard braked and car behind me almost hit me. Most of these I don't report since it's normal for Tesla FSD or adaptive cruise to be incapable of maintaining reasonable speed for a day trip - this was worse than usual and almost resulted in an accident.

Cruise control was engaged at 70mph. Auto without warning while traveling suddenly started severe braking. Driver was only guiding steering at the time ( foot did not touch brake). The dual lane highway was level and straight. There were no other vehicles in sight. The skys were overcast so there were no shadows. There were no overpasses. I have had this happen several times when autopilot is engaged but never when just cruise control activated. Sudden braking like this at high speeds could cause a vehicle following this auto to rear end that could cause the loss of control of this vehicle that would cause a life threatening event to occur.

The optional "Self Driving Option" we purchased for an additional $8,000 when we purchased this vehicle has never worked properly. The adaptive cruise control will brake for no reason, often multiple times per mile. It seems to be affected by shadows on the road and the vehicle mistakes these shadows for obstacles. The "Self Driving Option" will abruptly jerk the steering wheel in the direction of oncoming traffic and violently disengage. My wife and I find it to be unusable. Multiple service requests to Tesla have resulted in no actions.

PHANTOM BRAKING!!! Ever since purchasing the car in March 2018 and right up to the present, when using AUTOPILOT or more recently FULL SELF DRIVING (FSD), especially at highway speeds, the car will suddenly start significantly braking and slow down for no justifiable reason. This is dangerous enough that if the vehicle behind me is not paying attention, they could rear-end me. It’s totally unpredictable when this will occur, but it does happen frequently at highway speeds. This is a very well-known problem, but even after dozens of software update releases, Tesla has been unable to eliminate or even reduce the frequency of Phantom Braking.

The recent full self driving update that was received approximately one week ago has resulted numerous, substantial, and dangerous Self driving errors. The Vehicle struggles greatly to understand lanes and has on multiple occasions suddenly and without warning jerked the wheel to completely change lanes and then re-jerking the wheel to change back into the Original Lane. There has also been a shocking increase in phantom breaking while driving at highway speeds which is unsafe because other nearby drivers may slam on the brakes. The behavior of the vehicle has a times been so erratic that I could’ve gotten a ticket from an officer. Finally, the vehicle increasingly does not understand lanes and has several times veered into a left turn lane despite having a follow vehicle and despite being on a navigational Straight path, subsequently the vehicle then suddenly jerks the wheel back into the correct lane. This all happens very quickly and is not preventable by the driver even when hands are on the wheel and the driver is fully alert. I love my Tesla car. It is the safest car in the world. However, I feel very strongly that the company has been negligent and has definitely not been safety testing updates appropriately before wide release. I strongly recommend that guidelines be put in place to require Tesla to publicly report the number of FSD disengagement‘s every week. I also feel strongly that Tesla needs to permit drivers to roll back software to a prior version of full self

On June 1, 2022, we left on a roadtrip to CA from UT. Our Model 3 kept having incidents of "phantom braking," in which the Traffic-Aware Cruise Control and Autopilot systems would suddenly, inexplicably cause the car to slam on the brakes, and sometimes even flash a "red" steering wheel and an alarm with a warning that there was an object ahead —when there was NOT! This happened at least a dozen times en route on Highway 95 in Nevada, and continued to happen throughout our roadtrip on other highways until we returned home one week later on June 8, 2022. I have experienced this problem several times over the past year, and numerous other owners have already submitted similar complaints to NHTSA. Indeed, the TACC and AP behaviors are now significantly WORSE than when we first took delivery of the car over 4 years ago in April 2018. It is as though the car suffers hiccups, spasms, Tourette's Syndrome without any warning. I fear that one of these times we will be rear ended by a car behind or to the side of us. I can only speculate as to why this has started to happen, but suspect it is because Tesla decided to stop using its radar sensors a year ago and now only relies on its cameras. These incidents truly frighten my wife to death, so much so that she wants me to get rid of the car. I can't say I blame her, as the problems with the car's TACC and AP systems are now making it unsafe on our highways. If Tesla doesn't restore reliable, dependable, safe TACC and AP in the near futu

I was driving on a one way street when the car suddenly stopped. I was not at an or close to an intersection. There was a pedestrian waiting on the side of the road, standing between cars. He was not in my way. He was not even close to the vehicle. The car sounded audible warning and came to a complete stop. I believe this was the reason the vehicle stopped. This is the 2nd time since my 3 year ownership that this has happened. I provided Tesla with time stamps of the event during my service visit. They told me this is normal function of the vehicle. Just reporting this in case there is a more serious underlying issue that warrants additional investigation.

Our model 3 was purchased with Tesla’s “full self driving (FSD)” software installed in 2018. Throughout our entire ownership period, whenever FSD is active, there are specific locations known to us - mostly at certain points on freeways - where the car will “phantom brake,” in other words suddenly decelerate the vehicle very rapidly and require *immediate* driver intervention. For instance, there is a freeway interchange ramp that passes under a bridge and doglegs to the left. The car will always phantom brake about 200 feet before it reaches the bridge. This has been happening for years, and we’ve reported this defect and this specific location to Tesla many times. There are other locations known to us as consistent phantom brake triggers, but there are of course times where this occurs when we are not expecting it as well, and that’s when it’s most dangerous. We believe it may have something to do with the car’s sensors when they sense certain shapes or objects while the road is also curving slightly, as this is the most common phantom brake scenario for us. Again, this has been happening since we purchased the car in 2018. It occurs randomly at least a few times a month, and it *always* occurs in certain locations.

I was using Enhanced Autopilot on Tesla Model 3. It breaks automatically in middle of road for no reason even when there is no object in front of it. Its a life threatening situation because the vehicle behind my car will not have enough breaking distance and time at high speeds. It happens almost every month and specially under the reflection of bridges. I complained to service center and employees just ask exact time when it occurred and if exact time is not provided than Tesla employees does not do anything to resolve the issue. Looks like Tesla is putting many lives in danger.

I received access to Tesla’s Full Self-Driving system in late 2021. In the lead-up to that access, Tesla used a series of driver scoring metrics to select which users would get access first. Consistently, my metrics for forward collision warnings would show as alarmingly high, despite never coming within remote striking distance of another vehicle. On more than one occasion, a vehicle passing in other lane or turning left but in the other lane tripped the warning. At the time this registered as a red flag but more a bug of the evaluation system than the car’s recognition software. As time with the FSD suite has gone on, and subsequently with every new update, the phantom braking problem a number of users have described has plagued my experiences. Numerous times I’ve been driving with FSD engaged on two lane roads with no cars, shadows, animals or distractions of any kind around only for the car to suddenly and rapidly decelerate. Additionally I’ve received warnings repeatedly, without explanation, that the emergency braking system is disabling itself, then the warning will clear without any indication it’s either become reactive or is still disabled. Further, I’ve noticed through the new blind spot camera feature Tesla has released that my left rear-facing repeater camera can be blinded by the flashing of the embedded turn signal in the housing - but only the left signal, the right is not. This has led to, on more than one occasion, FSD disabling itself while active with litt

While using the adaptive cruise control plus autopilot, car suddenly and rapidly slows to stop. At each instance, there are no cars in front of me or any other obvious obstruction to cause the car to rapidly deaccelerate. It only happens on the freeway at freeway speeds. It is shocking and unnerving. When I quickly take back the control, I can bring the car back up to speed. So far, there has not been a car close behind me to cause a rear-end collision, but that is my fear. This has happened sporadically since I got the car, perhaps ten times total. The form asks for a date, but there are multiple across years so I put the approx latest date.

When driving on local roads and the interstate the card suddenly brakes for no reason when using auto pilot or full self driving. Sometimes it seems to be triggered by shadows from trees or other objects on the road and other times for no reason at all. I have been going 45 mph and the car suddenly braked to 30mph. I have been on the open interstate doing 70 mph when the car will suddenly and violently brake when there is a car on your bumper and this is very dangerous. If you dont keep your foot over the gas while driving and force the car to speed up it will cause an accident bc it will brake until the car is stopped probably. Somone needs to look into tesla and the phantom braking on auto pilot and full self driving. i have owned this car for almost 4 years and over the last 1 year this has gotten progressivley worse when they switched from using the radar sensor in the front to camera only vision called tesla vision. it is unsafe and im sure it's causing accidents today and needs to be investigated since Tesla cant seem to fix it.
