The car braked from 65 mph to 35 mph with no obstructing traffic, the car has done similar things on many occasions however. On the occasion of the most recent occurrence, I noticed that the car indicated a change in the posted maximum speed for that location from 65 mph (normal highway speed) to 35 mph, at which time it began slowing to the erroneous 35 mph limit. There was no reason for the change in speed, as there was no posting, construction or traffic.
Phantom braking can occur when vehicles are passing at night and during the day for no reason. There is no adequate control to enable the windshield wipers. Many menus to access the wiper controls. Not safe
I have had too many phantom braking incidents to count, it has happened hundreds of times since I bought the car. Most incidents were mild slowdowns (3-10 mph) on some two lane roads through interstate and but some were quite quite violent, 20 mph or more slowdowns in a second or two. For example, using only adaptive cruise control or with autopilot also engaged and no other vehicles nearby, the car suddenly slammed on the brakes before I was able to step on the pedal and stop the deceleration. If there had been a truck behind me following close, it would have rear ended me. This sort of instance happens regularly, at least once or twice a week. Mild slow downs, as noted above, happen a handful of times most every time I drive the car. It happens when roads are empty or full, and slow downs also occur even when lines in the road are clear, there is no traffic. It also can occur when I am cresting a hill or making a blind turn
late November of 2021, sunny weather, dry pavement. I was driving with Auto pilot (auto aware cruise control) on a 2-lane highway in rural MN. No traffic, I came upon a shadow cast by trees across the highway and the car suddenly braked. Later that same day, I was driving on a 4-lane expressway in a rural area—again with CC on. I was approaching an overpass that cast a shadow onto the roadway and the car suddenly braked. In both cases the car did not come to a complete stop but significant reduction in speed. Luckily in both cases no one was following close behind me. I have no interest in FSD and don’t agree with it as our highway/roadway infrastructure is a long way off from being ready. However, cruise control should be solid and I am now wary of using it and am tense under same conditions—I can’t rely on it. Tesla (Elon Musk) made a bad directive to have this system rely on cameras only. This system should also have LiDAR or at least radar. I informed Tesla of this issue. They acknowledged receipt of the complaint but never offered what they would do about it. Phantom braking is a big issue and FSD ought to be outlawed until infrastructure, vehicles and drivers are ready for it. For the life of me, I don’t understand why anyone would want FSD. Anyway, the issue with my car is not with FSD. Thanks
My car has experienced phantom braking for no apparent reason when on cruise control or auto pilot. Tesla claims to have to looked at the cars programming remotely and found no problem. I took the car to a Tesla dealer for a seat belt recall and asked them to also repair the phantom breaking. Again they said that they found nothing wrong with the car.
While driving down Interstate-5 my Tesla has been known to automatically brake from traffic safe speeds down to 40 immediately. It has happened multiple times. I have video to prove it as well. My video is too large at the moment but it does exist.
On to different occasions while vehicle was in Enhanced Autopilot the car braked hard for no apparent reason. If another car had been close behind it might have hit me. Problem has not been confirmed by a service center or the dealer, nor has the vehicle been inspected by anyone. The described actions happened in a construction area on highway I-25, both northbound and southbound. Problem appears to occur at off ramps.
Countless times, while driving on a two lane highway at speeds from 45-70 mph while on adaptive cruise control, the car unexpectedly braked when a vehicle was in the oncoming lane. This became so much of a problem that I needed to keep my foot on the accelerator if there was a car or truck in the other lane. It was dangerous because a car following me could have run into me or I could have skidded on ice. This has been happening for about a week. I think it is called phantom braking.
I recently brought my car in for routine servicing and informed the Tesla service technician that I’ve been experiencing significant lag with the rear (reverse) camera video feed since roughly early-December 2021. The rear (reverse) camera lag makes reversing hazardous, as any reliance by the driver on the the rear (reverse) camera feed can cause serious (potentially fatal) injury and/or property damage. I asked the technician to look into and address the issue; I told him I was aware there had been a recall and that I received a notice. He informed that they were unable to replicate the issue—which I find hard to believe, given it happens constantly—and that rear (reverse) camera lag is common in Model 3s as they age. My car is less than two years old—hardly classifying as “aged”. In looking at Internet forums, this appears to be a very common issue with Model 3s, and one that has yet to be resolved by the manufacturer through either hardware or software update(s).
Car will brake without any warning and with not reason to brake. Many complaints I’ve read online call this phantom braking. It has happened over ten times now and can be extremely dangerous as it will brake the car almost instantly and I have almost been rear ended because of it. Only matter of time before this happens and it results in a wreck.
Tesla model 3 has side repeater cameras that work as blind spot monitor cameras and provide visuals for safe lane changes. However, my model 3 suffers from a manufacturing defect in the camera assembly which causes the visuals to wash out at night due to light bleed from the turn signal. This caused an unsafe condition where i almost ran into a car in my blindspot being unable to see them on the camera visual. I raised the issue with service and they do not consider it a manufacturing defect. The defect however has been confirmed by independent researchers like here https://www.youtube.com/watch?v=_BUPsjguqdY
automatic braking happens for no reason. Happened multiple times on freeway .
On Tuesday 2/1/2022 approximately 9:20am EST, as I was sitting in a stop-and-go traffic, as the traffic was freeing up and started moving going roughly 5 to 10 mph, the vehicle automatically applied phantom brake - with a notification of emergency braking applied. I was not on cruse control or autopilot. i was in full control of the car yet it suddenly applied the ebrakes nearly causing someone to rear end me since the traffic had started moving.
I read this morning that there have been complaints about the automatic emergency braking engaging when it shouldn't and I would like to add my car to the list. I've had my Tesla a little over two years and turned off the feature about a year ago because it would hit engage the emergency braking when there was no reason to. After a software update a month ago Tesla reactivated the feature without my permission and the only reason I knew it was activated is because the brakes slammed while I was on the freeway. The forward collision warning also activates often when there is no threat of collision of near by. The details below are an approximation of the last time the emergency braking engaged but this happened probably 4-5 other times during the year I had it activated.
Emergency braking kicks in at times when there's an oncoming vehicle in the opposite lane. It happens on straight roads in normal traffic when the oncoming vehicle is maintaining it's lane. The car will suddenly slam on the brakes when there's no chance of a collision. Afraid of getting rear ended, I avoid using the cruise control and "autopilot" due to this erratic behavior.
Car decides to apply brakes for no reason
There are two problems: (1) braking and (2) windshield wiper operation. (1) Braking: When driving on a highway and going by an on-ramp on the right side, without any warning, the vehicle would, al of a sudden, slam violently on the brakes, even though the cars entering the highway are nowhere near where I would be driving. This has happened repeatedly to me, creating a hazard of a rear-end collision. The Tesla Model 3 in such cases would already be in a mode that would drive itself (by me having clicked on the right stalk twice). Additionally, the car often misreads a traffic sign for a different part of the road, such as a stop sign for a side road. The violent braking would take place in such a scenario also. (2) Windshield wiper operation: I'm not sure if this would qualify as a safety issue, but the windshield wiper operation doesn't work in automatic mode. I rely on this while driving in a rainy or snowy day so that I can concentrate on the driving itself without worrying about something else to do (turning on the windshield wipers). This is problem that has plagued the car right from the beginning, and to me, it presents a safety hazard. For example, about a week ago, I drove in bad weather (snowy) on a turnpike to get to a medical appointment. The weather turned bad, and cars would pass me by, splashing water/snow onto the car's windshield. The automatic mechanism should have kicked in to help me focus on the driving, but it did not.
Vehicle was driving on concrete-divided highway around 70 MPH. An ambulance with flashing lights came around a bend on the OPPOSITE side of the highway from the vehicle. Vehicle began to unnecessarily slow upon detecting the flashing lights.
My car has experience phantom breaking issues since 1 month after purchasing in December 2019 when using autopilot. Each time phantom braking so far only happens during interstate driving. During the two year period, it has happened over 10 times. Fortunately, no vehicle was very close behind me when phantom braking occurs. Oddly, no forward collision warning occurred during the phantom braking.
Vehicle approached an upward slope which triggered a forward collision warning and (unsafe) emergency braking.
I have experienced phantom breaking twice with my model 3. The first time was on the 101 freeway near Santa Clause Lane outside of Santa Barbara. There was no car in front of me or a hazard on the road but the vehicle made a sudden stop while I was traveling around 55MPH. The second occurrence happened on the 101 freeway near Santa Maria. Again, the vehicle made braked suddenly while traveling around 65MPH. The closest car in front of me was about 100 feet away. There was a car behind me but I was able to quickly hit the gas peddle to avoid an accident. I searched online at the time to see if anyone else had this issue but didn't have much luck. I'm thankful that I saw the Washington Post article.
After the OTA software updated to 2021.44.25.2 there were several changes to the graphic user interface and software system. Two direct issues of the update are: 1) The rear and side cameras that assist during backup now take longer to activate and have very jumpy (laggy) video feeds. So much so that the driver can backup at least 10 feet at low speed before an updated image is shown. This causes a very unsafe condition when backup up as there are multiple blind spots in the car. 2) The simplification of touchscreen controls requires the driver to be more distracted by having to navigate additional menus to turn on wipers, climate control, the radio, and safety features like the dashcam. Waiting on an appointment with Tesla but that is at least 20 days away.
Using either cruise control or Full Self Driving mode, driving on divided highway, experienced sudden hard braking not due to any highway obstruction, road hazard, other vehicle, or weather. Without warning car dropped out of assisted control and abruptly applied brakes. This happened yesterday at 2:10 pm, 2:53 pm and 3:01 pm.
There is A LOT of phantom braking, not just on specific stretches of highway around Austin, but almost anywhere. There is a specific spot on US Highway 183 north in Austin where the speed is set at 65 and the Tesla M3 will rapidly brake without any warning. There is a danger of being rear ended. I manually disconnect the ADAS in anticipation. I shouldn’t have to. In general, phantom braking is dangerous and could be attributed to using vision only sensors?
Driving on Autopilot on a city street at 35 MPH speed limit, while passing next to a UPS truck parked on the right side of the street at the curb, but slightly protruding outside the parking lane, due to its size, my car sideswiped the parked UPS truck, causing scratches on my car and totally obliterating my passenger side mirror. My vehicle did not stop or try to veer away from the parked UPS truck, causing at a minimum $700 damage to my vehicle.
https://youtu.be/_vSGyqX0HZg My car is constantly running red lights when on "Full Self-Driving". They claim that it should stop at red lights but it very often confused the left turn red for the green in the straight lane. The car randomly serves at other traffic for no apparent reason. The car randomly slams on the brakes super hard for no apparent reason. Full Self-Driving is UNSAFE
The lane departure assistance in my car was malfunctioning. Yes it is available for inspection if you would like. Today I.e. 10/25/2021, I was driving manually on Interstate 5. The car wasn’t on autopilot or cruise control. I was trying to merge into right lane and had my right turn signal on and made sure there was no one in my blind spot. As I was merging there was a warning signal and message displayed on the screen that read something like- lane departing corrective steering applied. The car was trying to pull me back into the lane I was departing from and it was applying sudden brakes to slow me down. I had to apply lot of force to the steering wheel to pull the car into the lane I was trying to merge. It was rush hour traffic and the cars around me were going pretty fast. It was a really dangerous situation and there could have been a big collision if I didn’t apply that force to bring the car into the right lane. There were no warning signs leading up to what happened today. But there was some malfunctioning in my car previously when the car just stopped without any warning on the ramp to my driveway. It’s a steep ramp and the car stopped all of a sudden and would not move. I contacted Tesla service about this and no action was taken whatsoever. I am really concerned about the safety of myself and the drivers around me not knowing what kind of bugs are going to come up in the future. Please take some action to make Tesla responsible for this.
I was parking at a trader joe's when the car suddenly accelerated by itself without giving me any chance to break to avoid colliding with the curb. My car got scratched underneath.
I get repeated warnings that the door pillar cameras are blinded. When I check it is condensation between the camera and the pillar glass. They attempted to repair this last year by removing a seal for better air circulation. The problem remains. In cold weather this happens, and it means that any of the automated functions that depend on the cameras can't work correctly or at all. They have no solution. The front camera actually has a defogger in the glass in front of it. Why tesla can't solve this problem is absurd. This happens while driving on any street or highway and is always the camera facing the sunny side, so moisture is evaporated from around the camera and condenses on the glass, which obscures it.
