Driver assisst function for cruise control/autosteer failed/malfunctioned. Applied Emergency braking systems while autosteer/driver control active. Multiple times on freeway. OTA software Updates require additional data downloading and are not required to install. Never received update and safety issues resolved via OTA are already being exposed and they are not allowed to do anything to prevent any damage or loss to the vehicle. Wifi at all government EV charging stations is a basic requirement.
Forward collision avoidance, Dec 31, 2023
After the latest update the Tesla autopilot feature is very unsafe to use. The screen constantly pings and nags the driver to pay attention drawing my attention away from the road. The system has become so sensitive that adjusting the AC down a degree causes the warning to pop up which distracts the driver and in my opinion is significantly less safe than the older version. The warnings are too sensitive and the noise/warnings flashing are significantly more distracting
Forward collision avoidance, Nov 20, 2023
The car's autopilot suddenly causes it to slow down without any apparent reason. There are no cars in front of me, and the speed limit hasn't changed. This unexpected deceleration is dangerous because the cars behind me may try to avoid me during the slowdown, which could lead to an accident.

Recently on a trip between Wichita Falls and Quanah Texas, my Tesla Model 3 while on autopilot repeatedly braked hard while traveling at 75 mph in moderate traffic. While this is a frequent occurrence with my model 3, this is the first time I felt at risk of an accident due to how hard the vehicle was breaking.
Vehicle speed control, Forward collision avoidance, Sep 11, 2023
Driving on I-5 North from Los Angeles to San Francisco with adaptive cruise control activated. Suddenly and without warning car activates emergency braking as if it sees an obstruction on the road but obviously road was clear of any obstructions. This happened 4 times then I finally decided to no longer use cruise control. This happened on a clear sunny day around noon time 9/8/23.
Forward collision avoidance, Sep 5, 2023
While driving on a divided four lane interstate state highway, during daylight hours, sunny, clear, dry, minimal crosswind, the car spontaneously braked while under cruise control from approximately 75mph to 45mph. There was no oncoming traffic or mirages. Fortunately no following traffic either because they would have either struck us or run off the road. This happened three times in a very short period and we haven’t used it since.
Forward collision avoidance, Aug 28, 2023
While the Traffic-Aware Cruise Control was engaged, my car abruptly tried to stop 8 times on the interstate while traveling at 80mph (the speed limit on the open stretch of road in central Utah). The weather was clear, no clouds, no wind, very light traffic, very good roads, no debris on the road, about 85 degrees, no shadows were cast on the road and during the day. I was on a 5 hour road trip. Out of the blue on at least 5 of the occasions, with a vehicle about a half mile or more ahead of me and no vehicle next to me my car abruptly braked - like emergency breaking - for no apparent reason. Two of the phantom braking occurrences happened when after passing a vehicle and I signaled and pulled back in to the right lane with at least a 3 second space, and my car emergency braked. This about caused an accident and thankfully it did not cause a road rage incident. Two of the times we were snacking once on vegetables when the car phantom braked and the bowl and vegetables went flying forward. Thankfully none of the times did I have my cup to my mouth as I would have gotten hot coffee on me and could have burned myself or have caused some destruction to my car. The passenger in my car safety was at great risk as well as everyone on the road near me. No warning that the car saw something or was going to emergency brake. My vehicle is available for inspection. I have not taken it to a dealer or elsewhere for replication nor has the vehicle or component(s) been inspected. There were never any warning lamps, messages or other symptoms of the problem prior to the failure. Also, the problem occurs 100% of the time I am at one particular place on a local freeway so it can be replicated. I do know that it will occur there so I plan for it. When I travel this road south bound there is never a problem but when I travel north bound 100% of the time my car will phantom brake regardless if it's day, night, clear or wet. Tesla needs another option for cruise control now!
Service brakes, Forward collision avoidance, Aug 27, 2023
Major phantom Braking at 70mph on interstate 5, 4 times the brakes slamed on as if yo had done an emergency stop from 70mph to 20mph fortunately we were not rear ended as I had my son and grandchildren in the car. The car was in cruise control on each occurrence I finally had to stop using it for fear of a major accident
Forward collision avoidance, Aug 27, 2023
Intro: This is a well known problem with Tesla cars. It's referred to as "phantom braking" in the Facebook Tesla groups and is wide spread. Using only cameras since around 2021 for adaptive cruise control, the car will "slam on the brakes" even though the road is completely clear ahead. This can easily cause an accident if there is a car following you. It has occurred several times since I bought the car Jan 2022. - malfunction component adaptive cruise control. yes available for inspection - a rear end collision could occur when the car's brakes are activated so hard that the car decelerates from 70 to 20 in seconds - the problem is well documented - no, no inspection by any entity. Tesla knows the problems exists - no, no warning of any kind

I was driving west bound on I4 August 12th 2023 at 1236pm at mile marker 45-47. I was in the left hand lane with the cruise control set at 73 mph. all traffic was moving well. there was no car in front of me. there was a car passing me slowly on the right. there was a retaining wall to my left. My car for no reason changed the setting on my cruise control from 73 to 35mph. this caused my husband and I to be thrown forward and I had to jam on the gas to try to regain speed. This was the 4th time this happened and the second time I have reported to Tesla who insists that there is nothing wrong with the car. I am scared if someone is following me closely I will be rear-ended at a high rate of speed. They continue to quote information from the manual and in the invoices insinuating that any incident occurring from this would be my fault. This is a terrifying thing to happen when there is no reason for the car to slow for any reason.

My Tesla Model 3 Phantom Brakes when using Cruise Control, particularly in the morning when the road is clear, no cars or obstacles in front or behind me. The NHTSA KNOWS THIS IS A PROBLEM AND I HAVE PREVIOUSLY MADE THIS COMPLAINT. I contacted Tesla to no avail. They did nothing. WHY HASN'T THE NHTSA DONE ANYTHING ABOUT THIS ISSUE. THIS IS DANGEROUS AS AN ACCIDENT IS WAITING TO HAPPEN.

While the car was parked in a parking lot, I get two notification stating “Sentry mode has turned off due to a sentry system error.” When I checked out the car, the car has completely failed to do any of the computer related task, leaving only the gear, AC, and Bluetooth was working. None of the cameras, GPS, sensors, brightness mode and many others were completely stuck. This continued until the next day. This happened without prior symptoms or warnings. I would have been in deep trouble if I have been driving at the time of the incident. When I took the car to the shop, tesla didn’t update the status for a week. After a week, Tesla told us that the Turbo A, Autopilot main processor chip failed. This caused the autopilot to go on loop. Therefore the whole motherboard needed to be replaced. This happened to a brand new purchased Tesla 2021 standard range. Which cost me $2404.00.

The vehicle was traveling in excess of 75 mph with only the autopilot system enabled. The vehicle brakes engaged by itself enough to squeal the tires and the rear end momentarily broke free from the pavement. I disengaged autopilot and drove for approximately 5 minutes. I reengaged autopilot and approximately 5 minutes later the brakes engaged again. I left autopilot disengaged for the remainder of the trip (~ 4 hrs) There were no other vehicles nearby but the breaking was severe enough that if another vehicle had been behind me, it could have caused a collision. The dealer acknowledges that this unintended breaking does occur on other vehicles. There was no warning that the vehicle would severely brake. The weather was clear with bright sun on route I25 south of Denver.

When cruise control is activated at highways speeds, vehicle sometimes brakes abruptly for no reason whatsoever. Issue is phantom braking. No other cars in sight, no changes in speed limits. Happened repeatedly on CA Hwy 46 between Interstate 5 and US 101 on 7/31/23 and 8/2/23. Similar instances observed on other highways, too.

My 2021 Tesla Model 3 is having MORE occurrences of phantom braking than ever before when I drive with the Tesla Autopilot/Full Self Driving system activated. I paid extra for Full Self Drive (FSD) and engage it mostly on highway driving. A recent software update from Tesla pops up a message on my screen any time I DIS-engage the FSD asking me "What Happened?" and offers me the chance to record a 10-second voice message regarding why I turned off the FSD. Yesterday, on 07/31/2023 between 12pm PST and 2pm PST I must have made at least five such recordings, each time for phantom braking suddenly jerking my car slower while I drove on major highways. In each case I was on a 55 mph highway (or faster). In all the cases, my lane was wide open with NO cars even remotely close to me. Sometimes there was oncoming traffic in the approaching lane of traffic, but not always. It certainly should not be braking due to oncoming cars in THEIR CORRECT LANE. Yet the car slowed down suddenly over and over again. This is a repeated problem, but I haven't had so many instances in one long drive. Yesterday I got fed up and resorted to driving without Autopilot for a large portion of my 150 mile trip home. Sudden braking - for no reason - substantially increases the risk of getting rear-ended by the car behind and frankly causes near-panic with people in the car itself.

“Phantom Braking”. Driving on the interstate approximately 75 mph using cruise control, auto steer, not auto pilot. Within a span of three hours today we experienced at least six episodes of the car emergency braking for apparently no reason. Immediately going from 75 to 40 mph. Thankfully no one was close behind us. We finally stopped using the cruise control. Now afraid to use it at all.

When vehicle is in cruise control or autopilot the car will suddenly brake without warning. It will do this numerous times and could cause an accident if a vehicle is following close behind.

Multiple phantom breaking events while driving at highway speed. Luckily there were no cars behind us, otherwise there could have been a collision. Caused driver and passenger whiplash and items in car to be forcibly displaced. There were no advance warning. Tried to report to manufacturer but they seem to be closed for the holiday, will try again to report after holiday.

Car “Phantom brakes” constantly when going over a hill when it does not have vision. The braking is aggressive at freeway speeds and poses a risk for rear end collisions or road rage incidents if people think they are being brake checked.
