2020 Tesla Model 3 SERVICE BRAKES,FORWARD COLLISION AVOIDANCE

While driving my Tesla Model 3 with self-driving engaged in excellent conditions, the car suddenly braked to a full stop. There was no apparent reason to do so and the driver did nothing. The road ahead was free of traffic, and no obstacles, pedestrians or animals were visible. It was possible to resume driving by turning self-driving off. Tesla forums online show many instances of others reporting similar problems in various Tesla models over several years. A rear end collision will ultimately be the result of this flaw if it hasn’t yet occurred.

While driving on the highway from philadelphia to allentown using I-476 north i was driving using cruise control and the car suddenly applied brakes ( phantom braking) there was no one either in front or sides or behind me. No accident happened

Driving on the freeway with the adaptive cruise control set to 78 mph. Traveling in the #1 lane, medium traffic, no vehicles in front of us for a while (in our lane or the #2 lane next to us). Roadway was dry, sun was overhead at that time of the day. Weather said it was 72 outside, so not excessively hot. While nearly cresting the top of a slight incline, the car hard-braked, taking the speed from 78mph to 58mph for no obvious reason. (Thank heavens the car behind us was following at a safe distance and was able to brake, too.) There was no debris on the roadway or any other reason why the car would need to brake. Suffice to say that we deactivated the adaptive cruise control for the remainder of the journey.

Hard Phantom braking incident when using cruise control with no vehicles ahead or next to me.

While driving on the freeway I5 in central California in the middle of the day there were no cars in front of me and the vehicle went into sudden PHANTOM BRAKING mode. I was driving at 75 MPH and it suddenly went into hard braking. Extremely dangerous. The vehicle behind me had to swerve around us. We could have been killed. I was using the cruise control but NOT the Enhanced Autopilot. This needs to be fixed. We escaped severe injury or death by sheer luck

This is the first and only time this has occurred as of today, 1/1/23. Around 11:45am EST, I was driving down a side street with no traffic coming towards me, behind me, or in front of me (and with no objects in the road). Suddenly, my brakes were aggressively applied and a warning came up on my screen saying it was the Automatic Emergency Braking that had been applied. It then released a few seconds after. I do not have the Autopilot option on my car, and I did not have any type of cruise control engaged at the time. If this had occurred in traffic for no reason it easily could have caused an accident.

This vehicle has the phantom braking issue whether you are using adaptive cruise or autopilot, and has happened at least 15 times in the past two years. Because of the sudden braking, we almost had a collision with a semi-truck coming up behind us on I-5 heading south the last time and the driver thought I was brake-checking him, making him very angry and giving obscene gestures at us for it. We reported it to the Tesla service center, and they basically said it happens, and they disclosed it in the operator manual. That is unacceptable. This is very dangerous, and lives could be lost in the circumstance where someone is following close behind. Tesla basically is saying it can happen and there is no fix which absolutely unacceptable and this car is dangerous to drive.

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.

When using autopilot cruise control, the car will brake hard for no apparent reason. I only use cruise control on limited access highways. When this happens, I immediately disengage cruise control and drive manually. This can happen at any time. I have driven the car cross country several times, driving all day. Some days it won’t happen at all, and on some days it can happen several times. I’m concerned that if someone is close behind me, they could hit me from behind. This has been happening for the past two years

Phantom braking: While driving down the highway for no apparent reason the car brakes and one time we had a car behind us that almost hit us. This is very dangerous and Tesla need to fix this asap. This has happened multiple times since around March 2022. The passengers in the car are slammed forward without any warning. Today was the scariest because we were almost rear ended and my 6 year old granddaughter was slammed forward. This is unacceptable.

I was driving on a deserted highway on Interstate 395 heading from LA to Mammoth Lakes. There were no cars behind or in front of us. I first put the Tesla into Auto Steering mode, and things were fine for a while. Then I experienced "phantom braking" with no warning. The car started to brake on its own, and then I disengaged auto steer and drove manually. About 30 minutes later, I put the car into simple "cruise control" and things were fine for a while. Then again with no warning, the car started to hit the brakes. I disengaged the cruise control and took over again. In both cases, there was nothing around us. The weather was clear and sunny. This shouldn't be happening. There was a recent Tesla software update where Tesla apparently discontinued its use of 'radar" for the auto steer and is only relying on the car's cameras. I don't know if this is the cause of my recent phantom braking, but this is concerning to me as it is a safety problem especially if there were any cars behind me.

My car when passing under signs or on two lane undivided roads will hit the brakes very aggressively. It’s difficult to reproduce and catches me and other drivers by surprise. The car didn’t do this during my first year of ownership, but now it happens several times a week. This will happen when using cruise control and autopilot. To me it’s rendered both features unusable.

automatic braking happens for no reason. Happened multiple times on freeway .

While driving at highway speed, the vehicle's automatic emergency braking unexpectedly activated, without cause or warning, which caused a very rapid deceleration of the vehicle. Fortunately, the traffic on the highway was light and no other vehicles were around, but this "phantom braking" had the potential for a major collision. This is the first time this has happened on this vehicle. The vehicle has not been inspected by the manufacturer and there were no prior warnings.

Phantom braking when using cruise control. Happens practically daily, but most recently this morning at 9:25am.

Car decides to apply brakes for no reason

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.

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.
