When traveling on a two-lane highway, oncoming traffic - especially larger vehicles such as semi trucks - cause the car to think it is going to hit the oncoming traffic and engages the brakes and sounds the forward collision warning. If the driver is not quick, there is danger of being rear-ended due to the sudden and unexpected braking.

When the car is in assisted autopilot, the vehicle will brake very hard when not necessary.
While driving on the highway and using auto pilot it has had multiple instances of phantom brakes doing highway speeds it will slow cars down rapidly and for no apparent reason. Really needs to get corrected.
I have experienced several incidents of “phantom braking.” The brakes automatically apply, slowing the car abruptly, when there is no discernible reason.
Phantom braking for no apparent reason. Worst occurrence was this morning driving home from work on cruise control, max speed cruise 73mph, suddenly my car braked on its own down to 59mph in 2 seconds. Very scary. My wrist hurts from that incident & my forehead almost hit the steering. Nothing in front & thank God no tailgating car behind me. This is not safe. It happens to me all the time but this was the scariest of all.
While using the autopilot feature on my Tesla, there have been several instances where the car will brake suddenly for no apparent reason. This has happened at high speeds and at slow speeds under various conditions. The braking is so severe that if a car was following behind they would have to react quickly to avoid an accident. Multiple instances over the last year.
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.
When driving at low speeds (below35) we have had 2 instances of the car braking with no obstacles.
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.
Our 2021Tesla Model 3, delivered in September 2021, has ongoing, repeated problems with sudden, unexpected braking, whenever cruise control or auto-steer is engaged. This happens regularly while driving on two lane highways, usually when a large sized vehicle is approaching in the opposing lane, but it also occasionally happens when there is no oncoming vehicle. Typically, an alarm also sounds and a warning light flashes in the car, warning of imminent collision risk. This happens every time we have used cruise control or auto-steer sometimes with nearly every large oncoming vehicle. This is unsafe because of the risk of a rear-end collision. The car dramatically slows. It also risks injury to the car occupants from being thrown forward unexpectedly. Along with the alarm and flashing signal, the braking is so dangerous and unnerving that it makes cruise control and auto-steer unusable. We have complained to Tesla of this problem. Tesla recently shipped the car to inspect more fully at its facility in Honolulu, but so far has reported that it is operating within "normal parameters." The rep suggested that the cruise control is not designed to work on a two lane highway such as we have on the Big Island of HI, although she says that it does not happen with every Tesla here. It occurs even on straight, level sections of wide, two lane highways with clearly marked lanes and wide shoulders. Tesla still has our car. When we read the Washington Post article explaining that many others are experiencing this problem, we felt we should report as well. We have advised Tesla that the cruise control and auto-steer functions in our car are unsafe and unusable in their current condition. We do not use cruise control or auto-steer except to test whether the problem has been fixed. We do not have full self-driving.
Hello, Driving on a snowy road around 20 MPH. Attempted to slow down in a straight line, used the brakes to try and slow vehicle to go into a driveway. Vehicle would not respond to any inputs. The brake pedal seemed frozen, coming off and back on the brake pedal did not change anything. There sounded like an ABS pulsing but it was not working. Post accident pictures showed it looked like the car was dragging one axle like it was locked in the snow. Car ending up grazing a mailbox post and afterword said 'take control'. I believe the car tried to do an automated braking maneuver which did not work. The road was covered in 1-2" of snow and the mailbox would have been a reference point in the distance. When turning the steering wheel away from the object that was hit, the car continued to go straight like the wheels were not attached. The car never veered left or right during this whole event even though i tried to turn.
I was driving north on Wisconsin route 14 at about 60 mph in my Tesla model 3 using the cruise control.. When a large transportation truck came from the opposite direction, my Tesla suddenly braked sharply. A Ford model F150 truck was following behind me and almost crashed into the back of my car. Fortunately the driver was alert and by sharply apply his brakes on driving into the ditch he avoided colliding with me. This could have been (and nearly was) a lethal accident. I would urge that you put a recall on a Tesla vehicles until this problem is corrected. I have contacted other Tesla owners and they have experienced similar problems. I contacted my local Tesla service station and they seemed unconcerned about the problem. I urge you to issue a recall before someone is seriously hurt or killed.
While driving in cruise control the car will break suddenly for no reason. I had a close call to where I was worried that the car behind me would hit me. The sudden breaking has happened many times. It's terrifying. I had to quit using auto pilot and cruise control when someone is following me for that reason. When I contacted Tesla about the concern they replied saying that they completed a hardware diagnostic on the vehicle and determined that there is no hardware failure. I provided them with the timestamps for the dashcam for several incidents. This is a HUGE safety concern. The cruise control system is dangerous.
Multiple random automatic braking occurred during Freeway cruising
Driving normally, with cruise control (not auto steering) engaged vehicle will spontaneously and dangerously apply emergency breaking. This happens regularly to the point I won’t use it. It’s going to cause accidents, especially when slippery conditions exist.
My new Tesla 3 deployed automatic emergency braking seven (7) times in a 5 hour period. The Tesla Autopilot was turned off due to reports of phantom braking like this from many other drivers in a Tesla online forum. Regardless, the car slammed on the brakes when there were no obstructions or cars in front of me. I almost suffered a rear end collision during one of these phantom emergency braking events, where the car suddenly braked from 70MPH to less than 40MPH. The malfunctioning component is likely the Tesla software that works with the forward-facing cameras which are installed as part of the Full Self Driving feature. While I did not pay the $10,000 for FSD, this system still operates for automated braking and lane departure. I have requested Tesla inspect the car, which has 482 miles on it, but am filing with you anyway due to the similarity between this experience today and the dozens of other complaints I have read about on the Tesla Owners forum called TOO.
On a recent trip, we started experiencing extreme issues with our car's cruise control and autopilot features. Specifically, when in cruise control or auto pilot, the car would randomly disengage the cruise control or auto pilot and start braking. Taking the car out of cruise control or auto pilot, restarting the car, etc did not fix the problem. We noticed the problem was much worse at night and when we were traveling on a two lane highway. We would be in cruise control/auto pilot and often when another vehicle would approach us from the opposite direction the vehicle would suddenly brake. While this happened more often at night, it continued to happen at any point during the day and when we were on many different roads/interstates. This seems extremely unsafe to have our vehicle hard braking randomly when we are traveling at high speeds (60mph+). We scheduled a service appointment with Tesla and were told that this is a software issue and we would have to wait for an update.
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.
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.
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
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
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.
I was pulling up next to a curb inside a neighborhood to park my car. I released my foot on the accelerator pedal to slow and stop my car. I slowly stepped on the brake pedal to switch the gear into reverse and my vehicle sped up very fast and hit the parked car in front of me and ran over the curb, my steering wheel also shifted to the right as if it was trying to dodge an obstacle on the road. It happpend so fast that I could not avoid the impact. I could have ran into a pedestrian and put their life at risk, or injured the person in the car that was parked, and even hurt myself badly. I've been getting neck pain and headaches. This incident was very terrifying and traumatizing. I tried to reach out to Tesla Service Center, but my tesla app was not working after the incident. The Tesla app was frozen for 10-15 mins after the incident. I kept trying to reach out to Tesla Service center and kept getting an automated response to utilize the Tesla App. Finally, the app started working again, I left them a message regarding the accident and photos, and they responded two days after, but did not address the issue about unintended acceleration until I kept asking why are they ignoring my concerns about the uninteded accerlation, and then I received a phone call from a technician. He said that I do not have to bring my car for inspection, instead they will just check the logs and could take up to 8 weeks to see what happened. Estimated cost for exterior damages according to Geico Insurance is 5344.74. Tesla Service Center denied having the car inspected physcially for any sensor issues and malfunction issues, states that I don't have to bring my car in at all, they will submit a report for engineering team to review the driving logs at the time of the accident only. My car is currently towed to a 3rd party body shop that is Tesla certified. No warnings from my car screen alerts or anything prior to the accident.
When driving with the adaptive cruise control on, the car will for no reason, briefly slam on the brakes for no reason. I have almost been rear ended twice because of this. check mark box above in this web page would not allow me to check the adaptive Cruise Control item.
On february 28, 2021 at 4:08 pm.. The approximate time of my arrival at workplace which is also displayed in my navigation. As soon as I'm doing a reverse to park my tesla for some reason and it did happen so quickly accidentally press the accelerator harder and as a result I cause an accident that my rear bumper hit the car behind me that was parked. The damaged was huge that it knock off the parked car front bumper, it broke the right headlight and buckled the engine hood. It really boggles me as to how it happened, I re-create the scenario at home it turns out and I truly believed that I got confused with the current driving mode as I switch the car to reverse while I stop to check my proximity, but the display changes to 'hold brake' font. Not knowing that it still in reverse mode, although the top left vertically displayed drive mode indicator still showing but it is too small/ minimal that it's hard to distinguish which one is active. For an owner that's new to this electric car it is confusing and specially you have other ice car you currently driving at home.tesla should consider an update to the display on the driving mode indicator. The default as you switch the stalk to d, p, n or r, that large font only display momentarily and it changes to your speed and then changes to ' hold- brake font icon'. Those display font p-d- r- n on the top left corner is too minimal and even lightly obstructed with the steering wheel. Even the font color is hardly distinguishable, the current drive mode is only bold in the same color. This is really a safety issue and should be addressed asap. Tesla model 3 display should be updated, the drive mode should be visible enough and permanent on the display. Look at the model s.. It has a very visible/ easy to distinguish your current driving mode. ( p-d- n-r ) [xxx] contact: [xxx] information redacted pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6).
When I test drove the tesla model 3, there was an option to turn regenerative braking to low. This allowed the car to have more of a coasting effect when one lifts the foot off of the accelerator. When I received delivery of the car, the ability to reduce the regenerative braking effect was not available. The removal of this feature is being discussed at length in online forums. The latest version of the owners' manual states that regenerative braking in the standard setting could cause the care to lose traction in winter conditions and that drivers should select the low setting. By removing this ability, tesla, by its own admission, has decreased the car's safety in winter conditions. A rapid deceleration of a car on slippery roads is almost guaranteed to induce a skid and make the car difficult or impossible to control. I find this extremely concerning. Tesla needs to bring the feature back, or publicize other compensations that may have been made unbeknownst to owners. I took delivery of the car on 12/24/20, but according to online forums this seems to have happened starting in october of 2020. A side complaint would be that tesla does not update the owners manual in a timely manner to coincide with the many software updates. The above example is jjust one of many, since the current manual makes a recommendation that is not possible to do in the 2021 model 3 refresh.
