What 412 owners told NHTSA about the 2023 Tesla Model 3 Bev

Brake Feature Malfunction Vehicle Details: •Model: Tesla Model 3 •Year: 2023 (approximately 1 year old) •Mileage at Incident: ~11,000 miles Incident Description: On 10/29, while manually driving my Tesla Model 3 on a public roadway, I experienced a critical braking failure. As I approached a vehicle in front of me that was decelerating, I initiated regenerative braking, then immediately applied the brake pedal forcefully. Despite pressing the brake pedal hard multiple times, the vehicle did not decelerate as expected and ultimately collided with the vehicle ahead. Throughout this incident, no collision warning, automatic braking, or other safety features activated, despite having all safety features enabled. This failure significantly impacted my confidence in the vehicle’s braking and safety systems. After the accident, I reviewed the Tesla incident report, which shows I attempted to brake but that acceleration was not reduced until the collision occurred. Despite the report documenting my attempts to brake, the system did not function properly, suggesting a potential mechanical or software defect in the braking and/or safety alert systems. Aftermath: •My vehicle sustained considerable damage. •I now feel unsafe driving the vehicle, particularly on highways, as I am concerned the brake failure could recur. Request for Investigation: Given the severity of this issue, I am seeking an investigation to determine: 1.Whether there is a defect in Tesla Model 3 braking systems that could result in brake failure under normal driving conditions. 2.If there is an issue with the vehicle’s safety features failing to activate appropriately. This incident has raised significant concerns regarding my safety and that of other drivers, especially given the car’s relatively new condition and low mileage. I would appreciate a prompt investigation into these safety concerns.

The system failed to detect the driver having a seizure and had no way for the passenger to break the vehicle. People in the vehicle and Others were put at the risk of a seizing person accelerating in a car that could not be prevented by the car or by the passenger. No dealer/service center has confirmed the issues. The vehicle is currently being inspected by police. No known warning signs/messages before the incident.

With the TACC system activated when traveling on a 2-lane road with a right-hand curve, if there is a semi-truck in the opposing lane, the emergency braking engages with a hard brake application. It can be overridden with accelerator pedal, but it endangers the car from collision with a following vehicle. There have been multiple incidents. I attempted to report the condition to Tesla customer support.

NHTSA ODI 11612673

When traveling on an interstate highway with a speed limit of 65 mph, with navigation system operating and with TACC engaged, the system sometimes resets the maximum speed to that of the speed limit of the exit ramp (usually 40 mph) when I am NOT exiting the highway. This results in rapid deceleration significantly below the prevailing highway speed with the potential of causing a rear end collision from following traffic. This is consistent some certain exit ramps along I-93 in NH, and is prevalent when traveling in the right traffic lane.

While using standard cruise control (without autosteer), car sporadically & aggressively brakes for no reason with no obstruction or cars ahead and while at highway speeds. With cars close behind, a serious, life-threatening accident could've occurred. Can not determine how to recreate issue on demand. This is a known issue with Teslas that has not been addressed by Tesla. I have not reported this issue to Tesla.

Since I purchased my car in July 2023, I’ve had multiple false forward collision warning resulting in my insurance premium increasing by sizeable amounts and has caused me undue stress. I’ve reported this problem to Tesla but to no avail. Today 8/9/2024, between 5:17 and 5:21 pm, while driving my cars forward collision warning was activated while no vehicle was in front of my but instead to a parked car on the pavement. This has happened multiple times and Tesla denies being aware of any issues.

On [XXX] around [XXX], my daughter drove her Tesla Model 3 on [XXX] from school. Two strange/scary accidents happened to two different Tesla cars (Model 3 and Y). It was raining with low/medium visibility. One of the cars was driven by my daughter, and luckily, both drivers were safe with very minor injuries. The cars had significant damage but were drivable, and there were no airbags out. These two accidents occurred within 3 to 5 minutes at the “SAME LOCATION.” When I asked them what happened, my daughter and other Model Y drivers described a sudden loss of control, with their cars spinning and becoming unresponsive to steering and braking. They then hit the guardrail on the center line. I checked the video recordings of our car multiple times; no vehicle-to-vehicle collision was involved. I also checked the road to see if there was any oil spillage, but the lane was clean. She didn't use Auto Pilot, FSD, and Cruse Control. The office recorded it as Hydro Plane in his report, but my concern was incidents that happened only to Teslas. Also, when I posted this incident on a Tesla WhatsApp group, multiple Tesla owners reported that they had a similar issue when it was raining. It seems like Sensors malfunctioning in the rain. Also, my daughter was driving below the posted speed (68/70), and she gave a written note to the officer too, but the officer recorded it as 70/70. I need to check that in the Wake County traffic court. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The contact owns a 2023 Tesla Model 3. The contact stated while driving at various speeds with the Adaptive Cruise Control or ADAS Self Driving feature activated, the vehicle would independently decelerate without warning. During the failure, there were no other vehicles or objects nearby. The Service Center was notified of the failure through the Tesla App. The contact was informed that since a time stamp could not be provided for each failure, the Technician could not determine the cause of the failure. The manufacturer was not yet made aware of the failure. The vehicle had yet to be repaired. The failure mileage was approximately 28,000.

On [XXX], I was driving my Tesla model 3 from California to my new home in Idaho as part of my move there. During the day, I had 6 or 7 situations where the car would suddenly go into full regenerative braking, or outright apply the brakes for no apparent reason. Most of these events took place of freeways at freeways speeds, or on highways (not freeways) at the local speed limit. Every situation was when I had supervised self drive or traffic aware cruise control enabled. These situations were extremely startling and in my opinion potentially dangerous. I don't want to imagine what might have happened if one of these "phantom braking" events had occurred with a heavy 18 wheeler behind me in traffic.

Tesla Motors has two self-driving features, a mode they call enhanced autopilot and Full Self-Driving. Enhanced Autopilot is used primarily on freeways, and allows the car to switch lanes without driver's assistance, while maintaining the speed of traffic. Full Self Driving is a separate system in and of itself that relies on far more sensors, and is far more complex, as it needs to be in order to handle all the nuances of allowing a car to drive itself on and around city streets. During the month of April ,Tesla previewed the supposed improvements in its full self driving mode by releasing it to everyone for free for that month. I was exiting the 101 freeway in Los Angeles, utilizing the enhanced autopilot feature to navigate myself to my destination. At this exit, the car makes a right on Main St, drives downabout 500 feet and then makes another right so that you're briefly traveling underneath the freeway from you'd just exited. As the car made that second right, while on what should have full self-driving mode, the car failed to navigate the angle of that turn and ran right into a steep curb at a fairly fast speed, destroying the right drive train, the right tire, the entire front bumper, and the cars wheel chassis and suspsnesion system all still have to be fixed. I believe the malfunction was caused by the car failing to properly switch vbetween enhancd autopilot and full self-driving if they utilize GPS to mmake that determination, because it felt almost as if the car was trying to switch into the lane to the right (which didnt exist there was the curb there) and not like it was attempting to negotiate or preparing to make a wider turn maneuver. I don't believe it even decelerated as it hit the curb. I broke my toe but otherwise am all right. Tesla won't honor their warranty and is threatening to repo the car they won't fix.

Full self drive FSD took car in opposite road direction, sudden lane changes, almost crash in upcoming traffic. Sudden stops in middle in road. FSD autopilot very dangerous driving that could cost crash. I can’t trust FSD

The contact owns a 2023 Tesla Model 3. The contact stated while driving approximately 72 MPH with the cruise control activated, the vehicle abruptly decelerated and nearly came to a complete stop. During the failure, there were no other vehicles or objects nearby. The cause of the failure was not yet determined. The local dealer was notified of the failure, but no assistance was offered. The manufacturer was not yet contacted. The failure mileage was 6,730. The contact stated the primary concern is that unexpected emergency braking for no apparent reason on our 2023 Tesla Model 3 was dangerous. The dealer indicated that their review of the data for the approximate date and time did not show anything and cancelled the appointment.

when I was driving my Tesla Model 3 with FSD exiting [XXX] , the FSD directed me to a wrong routing. I corrected the direction by taking over the FSD, the car then lost its full braking system. I was not aware of it until my car slipped backward at a stop and hit a car behind me. The other driver is good enough to let me go, but my Tesla back bumper was damaged. When I got home and read the message on the screen, I was told that the braking hold was disabled, autopilot was disabled, braking charge was disabled, and wheel alignment was disabled, and more. I contacted Tesla and make an appointment half a month later. I was also told that the Tesla recommends to have alignment adjusted every 6000 miles or every 6 months- while I was not aware of this, I thought Tesla is maintenance free. This was what I told Tesla representative then: If this disfunction is safety related, it should be mandatory, not recommended! I feel I was lucky that I only have a small accident, it could be worse. I just dropped my car to Tesla for repair yesterday, the estimated costs was originally $275, then it went up to ~$1500, then ~$1800, When I was talking to a representative, the costs increased to $2167 in a few minutes! I asked why the prices go up, they said the previous prices are mistakes, and if I don't want to pay, I can drive my car home! I believe this happens to many other Tesla users as well, it needs to be addressed before more accidents and damages. The fragile safety operation and the way Tesla treat its customer are not acceptable, at least to my case. Thanks for your attention, if you need more information about my report, or have any question, please feel free to contact me.

1. My 90 year-old mother-in law got trapped inside the car in very bad weather because my phone key wouldn't open the door after I got out and walked her elderly friend to the door of her house about 20 feet away, and then walked back to the Tesla. I've been able to reproduce the problem repeatedly, of course without my mother-in-law in the car. 2. Several near-misses because, unlike most other cars, the Tesla's blind-spot warning system, and many other basic control functions such as adjusting the windshield wipers, opening the glove compartment, etc, require you to take your eyes off the road. For example changing lanes requires you to look away from the lane you're about to move into to check the blind spot display on the touch screen. 3. Several near misses because easing up on the accelerator slows down the car forcefully 98% of the time, but does nothing 2% of the time. Specifically, accidentally flicking down on the right-hand control stick, which turns on the windshield wipers in most cars, activates cruise control and gives minimal feedback to the driver that cruise control has indeed been activated. In this circumstance, easing up on the accelerator pedal doesn't slow down the car at all. This is very frightening and unexpected and could easily cause an accident.

When using cruise control, my 2023 Tesla Model 3 will aggressively brake without warning or apparent cause. The braking is near maximal - as though the vehicle is attempting to prevent an imminent collision. This defect poses a hazard to occupants of vehicles behind mine as well as myself and my passengers as sudden braking could cause a rear-end collision and cascading loss of control. Inclement weather would have exacerbated the problem. This problem is documented. From my brief research it appears Phantom Braking has been the subject of a NHTSA investigation previously but for prior model years. The issue persists. When I questioned Tesla Service regarding this life and limb threatening problem their staff was aware and well versed at requesting the customer report the issue as though it were a minor software glitch. This is a significantly more serious problem necessitating an appropriate response.

I was driving behind someone when a suv came over from left lane into the right lane in front of the cars that were in Front of me and made a sudden turn into a business. I was already applying the brake and was the 3 second rule behind the car in front of me, however the car did not stop as I slammed on the brakes as hard as I could. There have been other times that the car will automatically slammed brakes on because it feels that it need to…when it’s not necessary at all. But the other day when I needed the brakes to help me stop abruptly…they failed to do so. I hit the car in front of me and was cited as well. If I had been going faster..this could have been way worse. This definitely needs to be evaluated on Teslas. I have a dahcam video that I’m unable to upload.

The adaptive cruise control of the Tesla Model 3, like other Tesla models, rely on the cameras for determining speed. While driving on the freeway the Tesla Model 3 began to abruptly break almost causing a car to rear-end me. This has occurred multiple times since the full self driving was released to everyone. I discovered that the software reads the freeway's "Minimum Speed Limit" signs as the maximum speed limit. I reached out to Tesla and was told that there would be a firmware up-date but one has not come out since.

Constant lane change while driving has gotten out of control. A couple of instance the vehicle has changed lanes without manual manipulation. This is getting out of hand and has certainly put risks on my family while operating vehicle.

The car phantom brakes constantly (at least every 10 miles) when using cruise control. You will be driving highway speed and the car will slam on the brakes for no reason,, making the cruise control dangerous and unusable

Driving normally down I-5, no other cars nearby and system suddenly phantom brakes. I am lucky no other cars were behind me as it may have well caused an accident. There were no other cars in front of me within at least 1 mile.

Back in February my Tesla Model 3 started acting up Emergency Brake was disabled, automatic vehicle hold was disabled, and traction control was disabled all issues I reported to the company app with photo. This problem stated when a software update happened after the Tesla app requested it.

As I was approaching my off ramp (which has a very tight turn), my automatic brakes failed which caused me to slam onto the brakes, and skid into one of the off ramp signs. All 3 of my children were in the back, the back driver side window shattered, I lost my driver side mirror, and there was damage done to the back door and wheel well (all on the driver's side). Although the damage looked minimal, no one was willing to work on the vehicle and I was strongly encouraged by my insurance company to claim it as a total loss. Granted, I had this vehicle for approximately 2 months, and had put at least $4,000 into it.

I decided to take my first road trip in the new Telsa Model 3. The trip was from Seattle to Portland down [XXX] which is a pretty straight and easy road. Because of this I decided to use the Autopilot feature (I purchased the FSD package) to help take the stress out of driving. (Note, this is my first Electric Vehicle AND even my first vehicle with a screen, so I stayed very aware and present the whole time driving with hands on wheel). After a while of driving I noticed the 'Arrow' icon on the maps, which indicates my car, wasn't centered on the road and was in fact about quarter to half an inch to the right of the road. I didn't think much of it as I've seen my Google maps do this before and after a little bit it readjust and fixes it. As the car was driving, it performed a SUDDEN deceleration and then put on the blinkers to turn left (which I'm on the interstate so there was no left turn). What I noticed was that because the icon on the map wasn't centered on the road, it thought I was off the side of it. When it came up to a side street, it then thought I was on the side street. Thus it rapidly slowed me down to the side street speed limit (35 mph vs the 70 on the interstate), and then thought it needed to turn left to get on to an on-ramp to get me back on the interstate highway. Luckily I was able to catch it in time, but I had to fight with the blinkers for almost a full minute to get them to turn off. After this happened again several more miles down the road, I decided to manually drive the rest of the way. Once I got to a charging station and powered the car off and on, the icon then was centered on the road again. I have noticed a few times since, that it 'gets confused' on what road I'm on and it is concerning that this has a lot of control over the car. It would be great to have a manual way to tell the map that I am currently on which road so it can then note that.
