2020 Tesla Model 3 Brakes Problems

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.

The complaint was filed on behalf of the contact's daughter. The contact's daughter owned a 2020 Tesla Model 3. The contact stated that while the contact's daughter was driving at 35 MPH, the brake pedal was depressed; however, the vehicle failed to stop as intended. The contact stated that the contact's daughter stated that the brake pedal felt spongy and unusual. The contact's daughter stated that the brake pedal was depressed to the floor; however, the vehicle still did not stop. The contact's daughter enabled the emergency braking system; however, the vehicle still did not stop. The contact's daughter beeped the horn to alert the nearby driver, and the dash cam independently activated. The contact stated that because of the failure, the contact's daughter's vehicle rear-ended the vehicle in front of the contact's daughter's vehicle. The air bags did not deploy. The contact stated that after the crash, the emergency braking system failure warning light was illuminated. The vehicle was towed to a local tow yard. The vehicle was condemned as a total loss by the insurance company. A Police report was filed. The contact's daughter was treated at the local hospital on the following day. The contact's daughter sustained headaches, whiplash, and a concussion. The manufacturer was not made aware of the failure. The failure mileage was approximately 49,000.

Automatic breaking was initiated as I was pulling in a driveway as I got closer to a large trashcan. The braking was aggressive and I now have concerns that it might've given me minor whiplash as it was so sudden. I have pictures of where I parked. I was about 6-8 feet away from the trashcan when the car automatically braked. I've pulled into this spot numerous times and never had this reaction.

My car did a Phantom break while I was driving on President George bush Turnpike E at the Dallas North tollway exit . I was taking the exit with in the speed limit of 40 miles per hour and was keeping the distance from the car in front. Suddenly the car did an automatic break and car slow down significantly. I got hit from behind and had damage to the bumper and trunk. Emergency break feature went out and an alert came. It is very concerning that the car stops in the middle of road by itself and being hit from behind. I would like an answer from Tesla. I have the dash cam footage of the accident

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.

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

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

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.

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

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.

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.

The car has regenerative breaking where the car is supposed to slow down when you lift your feet off the accelerator. Since a new update, some times (10%), when you lift off the accelerator the car does NOT slow down and will maintain speed. This inconsistent behavior is extremely dangerous and you don't know if the car will slow down or not. Tesla refuses to acknowledge this is an issue.

The contact owned a 2020 Tesla Model 3. The contact stated while pulling into the driveway and depressing the brake pedal, the vehicle failed to respond, accelerated unintendedly, broke through the garage door, and crashed into the vehicle parked inside the garage. The other vehicle moved away and damaged the garage. There was no warning light illuminated. The air bags did not deploy. The contact shifted into reverse (R), pulled out of the driveway and shifted into drive (D). The brake pedal was depressed but the vehicle failed to respond. The contact stated that he hit the curb to stop the vehicle, and the vehicle stopped. The contact stated that all the air bags then deployed. The vehicle failed to unlock. The contact rolled down the windows and cried for help until the neighbors arrived and opened the vehicle from the outside. The contact sustained bruises on both arms, and the contact's wife sustained bruises on the right shoulder and on the left leg. Both the contact and his wife received medical assistance. There was no police report filed. The vehicle was towed to a third party it was sold to. The other damaged vehicle was totaled. The manufacturer was notified of the failure, but no assistance was provided. The failure mileage was 9,600.

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.

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.

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.

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.

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.
