2020 Tesla Model 3 FORWARD COLLISION AVOIDANCE

My car was running in auto-steering mode. Last year it did phanthom breaking 3 times in freeway ( Arizona I-10 from casa Grande to tempe direction). Same happened on 2/14/22, it did phantom breaking for no reason. Speed dropped from 80MPH to 55mph. Luckily no one was ahead or behind me. This is high risk for drivers behind me.

On a recent trip, while using the adaptive cruise control on a divided, straight, flat four lane highway, the vehicle would randomly slam on the brakes for absolutly no reason, endangering us and other vehicles behind us, who were not expecting a random slam of the brakes. Driving conditions were ideal - sunny, excellent visibility and very low traffic. There were no oncoming or road-crossing vehicles and no vehicles in front of us on the divided highway to trigger the reaction. This happened 14 times over about 200 miles of driving on our return trip home and over 30 times on the trip out. On the outbound trip, I was using it on both the divided highway and sections where there was only one lane in each direction, so decided to just use the cruise control when there was a divided highway. This is a recent phenomenon, as cruise control has never done that before. The semi-autonomous mode does it all the time as well, so we stopped using it for fear of causing an accident.

The car repeatedly rapidly decelerates when passing semi-trucks on the highway. This creates a problem for vehicles driving behind my vehicle as it creates sudden braking for them and it creates a bit of panic for the driver of my vehicle due to the suddenness of the braking. This problem occurs almost every time the vehicle is driving over 60mph on a freeway and is midway in passing a semi-truck trailer truck. The dealer has replaced the camera but the problem still occurs. Collision lights occur at the time of the error but no other warnings occur.

While using the autopilot function car unexpectedly brakes almost to a stop for no apparent reason. This happened in different driving conditions, day, night, other cars around and on empty roadways, both divided and connected two and four lane freeway and side highways. Brakes so hard that objects fly off the seat and cars traveling behind my vehicle have had to break themselves and or change lanes.

Autopilot regularly will panic brake (phantom brake) it also will often randomly change the set cruise control speed from 70 to 35 or from 75 to 35. This is a dangerous system that should not be allowed on the road.

The contact owns a 2020 Tesla Model 3. The contact stated that while utilizing the ADAS features including the Adaptive Cruise Control, the vehicle independently applied the brakes while driving at highway speeds. No warning lights were illuminated. The vehicle was not diagnosed. The vehicle was not repaired. The dealer nor the manufacturer was notified of the failure. The failure mileage was approximately 25,000.

Phantom braking issue. Cruise control set at 68mph. Medium freeway traffic at 7pm. Noticed disabled car ahead on the shoulder. No danger. As we approached the car, my car went into a panic stop as if it thought a collision was ahead. Car braked and skidded. I was able to regain control and accelerate and avoid a rear end collision. No waring or repair issues

"Phantom braking" issue. When car is in autopilot or enhanced autopilot mode (an upgrade I purchased after I bought car), will brake suddenly and firmly at high speed for no apparent reason. Until September 2022 car would very occassionally brake too easily in autopilot mode (perhaps 3 times in two years), but it was not sufficiently forceful or frequent to cause alarm. However, on 9/26/22 and 9/30/22 during daytime driving car violently braked on highway at least 6 times over approx 500 miles of driving. Fortunately, these incidents caused no damage, collision, or injury. There was little additional traffic on the road at the time. However, items in car, and two cats in carriers on back seat were thrown forward and displaced, and the incidents were very frightening. When I realized this was happening in autopilot modes, I stopped using feature completely and have not since. At 11/19/22 service appt for issue at Alhambra Tesla dealer I was told this was a "known issue" with no current solution; however, I was told that the more I used autopilot and hit accelorator during phantom braking, the faster car would "learn" not to do this. Given that taking the risk of continuing to use autopilot at all poses a serious risk of injury, I am truly shocked at the suggestion that I continue to use this feature and essentially train my car not to be dangerous. Via Tesla app I gave information and dates to Tesla prior to service appt and was told that they would attach vehicle log to file for service visit.

phantom braking/slowing. Also, please do what you can to stop deployment of FSD by the end of 2022. Not only is the car and drivers not ready for it, the infrastructure is not as well. In addition, the 100% reliance of cameras for auto aware CC and FSD is absolutely flawed. Tesla must add radar—better yet, LiDAR—to their vehicles irrespective of FSD but, absolutely for FSD if they insist on pushing it before drivers, infrastructure, and the vehicles are ready for it. My opinion, FSD should never be allowed on any vehicles—maybe by the 22nd century…

This vehicle has frequent episodes of phantom braking at highway speeds. No obstacles, stop lights or other vehicles in proximity

Last March we drove to Tampa Florida and on 3 occasions using cruse control the car came almost to a stop felt like I hit brakes very hard. each time we were in the middle of a highway with no cars around us. I called Tesla they said do report a bug. The weird thing is each time it was at dusk. I just read an article and thought to report it. I am not sure if Tesla reported it. It has not happened in the last 6 months but very scary when it happens.

Phantom braking has occurred numerous times on cruise control. No cars or other objects nearby. Set up appointment with Dealer but the service dept said they are aware of the issue and at this time nothing can be done.

While in cruise control the car baraked excessively on a straight 4 lane divided highway even though there was no other vehicles in front, to the side or coming on the opposite direction. This happened on 101 north of Paso Robles

I had 2 incidents of "phantom braking" in the vehicle this past week. I was just in cruise control, and the roads were in good condition, visibility and skies were clear, there were no cars in front or behind me, and we were cruising about 70 mph. In 2 cases, the car just slowed by itself for a few seconds and then I disengaged the cruise control. In 1 other cases, the car made an abrupt braking from 70 to about 40 mph. I disengaged and then did not use cruise control any longer. I've been told by Tesla service that the car's "radar" feature was replaced/disengaged in lieu of Tesla Vision, which apparently is in "beta" phase. In any event, this should not be happening, especially in just basic cruise control under ideal road conditions.

Car randomly apply brakes when no obstacle present while Auto Pilot is engaged. Also gives a lot of false collision warnings.

The forward collision warning censor gives an absurd number of false positives. I have Tesla insurance, and the insurance rate is HEAVILY affected by forward collision warnings. Nearly every day, one is triggered with -nothing- in front of me. I mean empty road ahead. Or, a car is about 7 car lengths ahead of me, they begin to slow down to make a turn, begin their turn, and nearly exit the lane. Without slowing down, and still 3 car lengths ahead, I get an angry forward collision warning and a major increase in insurance with -zero- risk of accident. It seems to happen most frequently at low speeds

The car has randomly braked multiple times, for no reason at all. Maybe shadows or mirages?

I have reported multiple times that the car suddenly brakes in the middle of the express way with no apparent reason. This issue is known as phantom braking. Tesla postponed the diagnosis of the car multiple times and I was told by the service department that the problem was going to be fixed by replacing the radars when I left the car on May 16, which they did not do. The last events of phantom braking occurred multiple times and even I continued stepping on the accelerator, the car continued to engaging with the emergency braking. This is a safety issue and the company has failed to fix it

"Phantom braking" issue is very real and very dangerous on my vehicle. Problem occurs while operating the car with Autopilot engaged such that the adaptive cruise control is in operation. Problem happens with or without also having the auto-steer function engaged. Problem is that the vehicle will suddenly, very unexpectedly slam on the brakes. This can cause the driver of the vehicle to go into panic mode and for obvious reasons is also very dangerous for vehicles that are following the malfunctioning Tesla. Sometimes, this sudden, hard braking occurs when a vehicle coming toward the Tesla makes a left turn in front of the Tesla at a VERY far away and VERY safe distance - so safe that the driver of the Tesla is caught completely off guard when the Tesla decides to slam on the brakes. And cars behind the Tesla are also caught off guard. Other times, this "phantom braking" happens for no apparent reason at all - totally out of the blue. I am now very leery to use the autopilot feature, even though that was one of the vehicles biggest selling points. I am positive that only reason I have not been rear-ended is I have quick enough reflexes that I have been able to push my foot on the accelerator quickly enough to over-ride the sudden braking before the car behind me hit me. I have called Tesla's service department about this issue. They do acknowledge the issue, although in a vague manner as if they are reluctant to fully admit how prevalent and serious the issue is. I've asked if there are any adjustments I can make to the various settings that might reduce this problem. The representatives that I spoke with had only anecdotal experiences from conversations with other customers complaining about this problem. My Tesla has several control settings which could be related to this problem. They are not well explained in the owner's manual, plus some settings appear to overlap or conflict with similarly named settings. Confusing! Many incidents, so is date is not specific.

The contact owns a 2020 Tesla Model 3. The contact stated while driving 75 MPH with the cruise control activated, the vehicle experienced phantom braking. The vehicle was not diagnosed nor repaired by an independent mechanic or dealer. The manufacturer was made aware of the failure and informed the contact that a technician would inspect the vehicle at the residence. The failure mileage was 26,498.

The car suddenly brakes when the accommodative cruise control or full automatic driving is engaged. This happens at random times when driving on the highway. The braking is sudden and severe requiring driver intervention. Only happens with cruise control or full auto. Has happened several times since the car was purchased.

Vehicle at least once per day automatically brakes. Phantom emergency brakes for no reason randomly when going straight on the road no objects come into obstruction for the cameras. Common Tesla problem. This needs to be fixed. It has almost caused a few accidents for me now.

Autopilot has repeatedly slowed down very quickly and suddenly on multiple occasions over the past year for no reason on a completely clear road. It’s the same “phantom braking” issue as described in this article: https://www.cbsnews.com/news/tesla-phantom-braking-nhtsa-750-complaints/

While traveling on highway with Full self driving engaged car would occasionally brake and had to quickly press on the gas pedal for fear a car would hit me from behind. This seemed to happen when I approach an overpass but not most overpasses and typically happens once or twice during highway trips of about 80 miles on NJ garden state parkway. I had not reported this to Tesla or had the car checked for this issue and report it now seeing that there were formal reports filed on this issue to NHTSA. I do not recall whether any warning lights or audible alerts occurred during these incidents. First occurred after I took possession of car a couple of years back.

Car engages self breaking while on autopilot without any particular reason. Repeated brhavior happened and almost caused rear end collision.
