I am submitting this report to the federal safety agency regarding a recurring safety issue with my 2018 Tesla Model 3 involving unintended “phantom braking.” On multiple occasions, my vehicle has abruptly decelerated without any apparent obstacle or hazard present. These incidents have primarily occurred while using driver assistance features such as Autopilot and Traffic-Aware Cruise Control on highways and well-marked roads under normal driving conditions (clear weather, dry pavement, consistent traffic flow). The braking events are sudden and significant, creating a serious safety risk—particularly when other vehicles are following closely. In several instances, the deceleration was forceful enough that I believed a rear-end collision was likely. There were no visible triggers such as overpasses, shadows, vehicles merging, or roadside objects that would reasonably justify the system’s response. Below are details to assist your investigation: •Driver Assistance Features Active: Just cruise control, not auto pilot on these occasions •Weather/Road Conditions: Clear and dry •Frequency of Occurrence: This is an ongoing problem that has occurred dozens of times in the past few years. The March 30th incidents were only the most recent ones. •Any Warning Messages or Alerts: No This behavior appears unpredictable and difficult to anticipate or mitigate, increasing the risk of a crash. Given the potential safety implications, I respectfully request that the federal safety agency review this issue to determine whether it reflects a broader defect affecting other vehicles. Thank you for your attention to this matter.

Repeatedly and randomly, with cruise control (not FSD) engaged, the car would brake, sometimes aggressively. The last time, it braked so hard the tires or brakes squealed and the car swerved slightly before I was able to regain control. This was on the freeway (in Colorado, if I remember correctly) while I was cruising at 70 or 75 MPH. I decided that that was the last time I would use cruise control; it was just not safe. I had an appointment on October 22 to take the car in for service. But then a friend told me this was called "phantom braking" and that there was no fix. A friend suggested that I contact the federal safety agency.

On 9/6/2024 I was driving on I-10 E going about 70 mph in the left lane. I had engaged the cruise control but not the Autopilot because I’ve had dangerous experiences with the Autopilot phantom breaking and misinterpreting cracks in the road as lane markers and dangerously changing lanes. So even though Inoaid thousands of dollars for Autopilot I never use it. So I was driving approaching a big rig in the lane to the left of mine and the sun was low in the sky casting a shadow on the road. The car thought the shadow was a car and slammed on the breaks and almost came to a complete stop until I pressed on the breaks to release the cruise control. We are very lucky the car behind us didn’t hit us. The car behind us almost hit us and my passenger and I both sprained our necks. The same exact thing happened 5 minutes later. After that I am too scared to use cruise control which is very inconvenient when on a road trip. My car is a 2018 Tesla Model 3 that is equipped with LIDAR radar when I bought it, however Tesla turned this feature off awhile back. I never had issues with cruise control when the LIDAR was still enabled. I am very angry that a carmaker can turn off a safety feature that I paid for without my consent. I would have bought a different electric car if I had know I’d have to go back in time to the 1990’s before cruise control was invented. Most cars use some kind of radar for their cruise control systems and this seems to much safer. There are many, many complaints on line of other Tesla drivers having lots os problems with phantom braking. This is an important safety issue that needs to be addressed immediately.

I got a recall notice from Tesla and Tesla is still in safety violation and is refusing to fix the issue, so I need your help to force Tesla to fix their abusive ways. The recall 23V‑838 is related to "when Autosteer is engaged". Autosteer/Autopilot/FSD now DISABLES even when NOT engaged, alleging "improper use" when it wasn't even being used. It also disengages Autosteer/Autopilot/FSD while driving if it detects "improper use" (even if it's detection system itself is buggy), forcing the car to slow down like in the middle of the freeway! When the battery is low and there's only a mile or two to go to a charger, the software will slow down and force the car to pull over to get a tow, taking on average 2 hours to get a tow truck to go 2 miles, rather than allowing the driver to reach the charger with the remaining battery it shows. Tesla keeps changing the battery percentage for when it shuts down. It used to be 0%, then 3% and recently 6%. This randomness creates "range anxiety" and distrust in the battery percentage being a useful indicator. Tesla should use 0% as "shut down" and leave the rest of the battery as "drivable" to reach a charger to have an accurate indicator. It also flashes alerts on the SCREEN to "Pay attention to the road", which is ironic to have a screen display to distract attention to the screen... rather than pay attention to the road. Tesla took AWAY my Autosteer/Autopilot improperly, and no one in the Service Center or Support at Tesla knows how to fix this BUG or give it BACK to me, so I can drive SAFELY like with lane centering. I paid $10,000 for this "safety" that Tesla takes away at random, claiming they can do whatever they want because they've now labeled it BETA software! This is an abusive practice the federal safety agency should force Tesla to stop doing and give the power back to responsible drivers like me. Tesla abuser names include [XXX] and [XXX] . Teslas also don't detect cars in blind spots and still phantom brakes. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORM

There are two issues. 1) The adaptive cruise control brakes for no reason. If someone was behind me they could've rear ended me. 2) At night the blind spot camera is flooded by the turn signal and it's hard to see the blind spot warning. When the turn signal is on the blind spot camera shows on the screen and blind spot warning shows up as a red shaded area. It's hard to see the warning itself because the turn signal light floods the screen.

The contact owns a 2018 Tesla Model 3. The contact stated that while driving at various highway speeds with the Forward Collision Avoidance Adaptive Cruise Control activated, the vehicle experienced phantom braking, causing the vehicle to stop abruptly in the middle of the highway. The contact stated that the failure had occurred on four separate occasions. The cause of the failure was not yet determined. The manufacturer and local dealer were notified of the failure, but no assistance was provided. The failure mileage was 27,000.

while driving my Tesla Model 3, using the ACC and self-steering option, I occasionally get "forward collision warnings" when going over a hill, where you can't see the road until you get over the hill. I have also had the same "forward collision warnings" on a flat stretch of road when there is clearly nothing in front of me in my lane. I have also been experiencing "phantom braking" episodes, noticing a pattern where they will happen as I approach a bridge overpass, as if the car thought the bridge overpass was perhaps an obstacle. These occur on a fairly regular basis, as in, at least 5-10 times per month. I drive a lot of highways, and drive approx 20,000 miles per year

Vehicle has experienced dramatic increase in so-called phantom braking incidents when adaptive cruise control is turned on. The vehicle suddenly and forcefully brakes for no apparent reason even when there are no vehicles or other hazards in front or on the sides of it. I have revisited sites where the incidents have occurred to see if there is some environmental factor such as reflective signs that might have triggered the incidents but have been unable to replicate them. They are completely random. I am aware that this phantom braking issue has previously been reported but based on a review of various Internet sites such as Reddit, owners have reported a dramatic increase in incidents over the past month or so.

I have owned my Tesla Model 3 since early 2019. The adaptive cruise control worked incredibly beautifully for years up until a few weeks ago - I think sometime in June 2023 (could have been May 2023). All of the sudden, I was *frequently* experiencing phantom braking, ie. braking with no explanation, while using adaptive cruise control. Sometimes the braking was gradual, other times more forceful. It would happen at random places - Sometimes in/near intersections or around other vehicles, other times just out on the open road with no vehicles or stoplights anywhere in sight. Even on a 20 minute drive, it can happen three or four times. To me, this is a severe hazard. I have a disability, and I purchased this vehicle because of the incredible safety features. Prior to this, it has 100% lived up to what people said about it - just amazing. But now, the very reason I purchased this vehicle, its advanced safety features, I find not just unreliable but somewhat terrifying. I *believe* that Tesla may have (effectively / unintentionally) disabled the built-in radar in vehicles like mine. This is because I've read online accounts of people with the same year having the same problems as mine, also at around the same time that mine started. Specifically, my model year has radar built in. But I understand that newer Teslas rely solely on cameras, ie. "Tesla Vision." I understood that because my vehicle physically has radar installed, that my adaptive cruise control would still work at least as good as it had in the past - certainly not worse. If this can't be fixed I'll be forced to sell the car, which I desperately don't want to do, as I love the car and I think the world of Tesla. I just want it to work properly again.

Multiple "phantom braking" events in which the car, on a clear day & no cars around, would suddenly slam on the brakes and try to stop. No messages were displayed on the screen. Tesla Service seems uninterested as it is a "software" issue. I tried a full reset of the car with no improvement.

On a trip today from Pasco wa to Spokane WA (us395) there autopilot and full self driving would randomly phantom brake for no obvious reason. It happened every 5 minutes or so in both directions. Scary and dangerous.
