The contact owned a 2022 Tesla Model 3. The contact stated while driving at approximately 65 mph with the "auto pilot" engaged, the vehicle approached another vehicle in traffic from behind and had gotten to close. The contact stated that she depressed the brake to slow down when the vehicle inadvertently accelerated at high speed. The contact steered to the left to avoid rear end crash with vehicle directly in front. Additionally, the contact stated that the steering wheel had become hard to turn and the vehicle crashed into the highway divider. The vehicle front end had crashed into the divider wall and the vehicle ricocheted across four lanes of traffic and ran off the roadway onto the right shoulder and was stopped by having crashed with small trees and bushes. The contact stated she did not notice any warning lights. The contact stated that she had been transported by ambulance to a trauma center. The contact stated that she had compression fractures of her spine, suffered soft tissue damage to her neck, right wrist soft tissue damage and rib fractures on the left side. The vehicle had been towed to an impound lot, the police were on scene and wrote a report. The contact stated that her insurance provider had declared the vehicle a total loss. The manufacturer had been informed of the failure. The failure mileage was 4,400.

The contact owns a 2022 Tesla Model 3. The contact stated while driving on the highway at 70 mph, with the cruise control activated, the vehicle came to an abrupt stop. There was no warning light illuminated. The vehicle was not taken to be diagnosed or repaired. The manufacturer was notified of the failure. The failure mileage was approximately 2,900.

The contact owns a 2022 Tesla Model 3. The contact stated while driving approximately 65 mph, the vehicle inadvertently started braking with the cruise control was activated.

When I'm driving on an interstate highway with hot lane to the left of my direction of travel, the car erroneously senses the speed limit as 65 mph (the speed limit for the adjacent hot lane) rather than the actual speed limit of 55 mph in my lane. The result is that when I am using the adaptive cruise control in the situation described, the car suddenly and without warning accelerates by at least 10 mph over the posted speed limit. This has happened repeatedly and makes use of the adaptive cruise unsafe.

The contact owns a 2018 Tesla Model 3. The contact stated that while driving 70 mph with the cruise control activated, the braking system erroneously activated causing the vehicle to abruptly stop in the middle of the road. The contact indicated that during the failure there were no objects or vehicles nearby to cause the braking system to suddenly activate. The cause of the failure was not yet determined. The manufacturer was notified of the failure. The local dealer was not yet contacted. The failure mileage was 5,000.

I was driving straight on a highway using traffic aware cruise control when the car suddenly braked hard. If someone had been driving behind me too closely I would have been rear ended at a high speed. I've seen online that people refer to this as "phantom braking," and it seems to be a common issue with Tesla cars.

My wife and I live on a two-lane state route in the country. We were headed home from the farmers' market this morning around 10 a. M. , headed down a hill with three cars behind us. There was an 18-wheeler headed up the hill. I had the cruise control on and traveling 55 mph in a straight line with no curves in sight. When the 18-wheeler coming up the hill was 7 car lengths ahead of us in the opposite lane, my car automatically braked hard enough to bring our speed down to 35 mph before I could override and accelerate. My spouse said, "I hate this car. It's going to get us killed one day. We could have been rearended. " I have used conventional cruise control to drive for more than 20 years, even in town, to keep from inadvertinly speeding. Normal cruise control doesn't behave in this manner. This is my first report of a recurring problem.

The rear trunk lid popped open by itself while driving. I was the only person in the vehicle, and I did not pop the trunk lid. It should be noted that the trunk lid can not be opened by the occupants while the vehicle is in motion. The selection on the screen is not available, the trunk 'button' is not accessible on the screen while in motion. There is no mechanical release. When the trunk opened, it caused the cruise control to become unavailable.

I took delivery of my Tesla at the beginning of April 2020 - I have not been out much because of lockdown. On one of my early journeys the car spontaneously accelerated. I was shocked but thought I had inadvertently done something eg cruise control or heavy foot even though I believed it was totally unprompted yesterday I was driving at slow speed about 20- 25mph approaching a pedestrian crossing when the car spontaneously accelerated- it was undeniable ! I took my foot off the pedal but it didn't slow - I jammed on the brakes to halt the acceleration. When I arrived home I googled 'spontaneous acceleration ' to see what had caused it and was horrified to discover there is a lot of allegations to Tesla which have been denied. I rang Tesla and they said they'd send a mobile engineer within 4 days!!! I live in uk but am aware you are collecting data on the matter - I live in uk so filing the form didn't allow a uk phone number- +[xxx] information redacted pursuant to the freedom of information act (foia), 5 u.

See attached for details. We have experienced at least two unexpected hard braking incidents in our 2020 Tesla Model 3 equipped with autopilot. In one incident, just as autopilot was engaged, the Tesla braked suddenly from 65 mph to 50 mph. Other drivers were forced to brake hard to avoid collision. On the same day, while in adaptive cruise control, the Tesla suddenly braked hard at a speed of 78 mph, down to 60 mph. Tesla has been notified by others who have had similar experiences, so they are aware of this hazardous problem. The issue has been reported by many on Tesla social media sites since at least 2018. It still has not been corrected. I plan to send a copy of this report to Tesla.

While reversing into my 2 car garage into the center of the garage space, I came to a stop (auto hold after braking to a stop but with the rear camera view on display) when I reached far inside (to be able to close the garage door). Using the homelink, I closed the garage door (waited till it fully closed 2 ft from the front nose of the car). While I had both feet flat on the driver floor mat, I tapped the right side gear stalk down to switch from reverse to drive, the car jerked forward and the display screen closed the rear view camera. I normally drive forward slowly to put the nose of the car about 1 ft from the garage door (this allows me walking space at the rear of the car while parked). In the past I have noticed less severe 'jerking/lurching' forward when going from reverse to drive while leaving my garage when I would maneuver in the garage space with two cars parked, I thought it was my imagination. In retrospect this car has done it several times over the span of a year. Consumer states that vehicle seems to be activating the cruise control feature when the car is at a complete stop.

My Tesla Model 3 keeps unintentionally and erratically braking while in motion using the autopilot or cruise control on the highway. I have multiple dates and times of this incident happening. This is known as "phantom braking" a false positive that the autopilot system engages in. This happens at random areas and time (day or evening) on the freeway. I have contacted Tesla service and they have given me the cold shoulder and stated there is no fix for this.

When I shift the car into drive and use the accelerator pedal to move the car forward and it works fine. When I release the accelerator pedal, the car accelerate and requires me to brake. This occurs at low speed. I have taken the car into Tesla and they said user error. The cruise control engages when I shift into drive. This has occurred several times since I have purchased the car.

While driving at ~70mph on the freeway, we attempted to open the web browser app. The entire ui froze, during this time I could not exit autopilot by pressing the brake pedal. The car would decelerate when pressing the brake, however after pressing the brake the car immediately accelerated back to the set cruise control speed. After around 30 total seconds (around 10 seconds after attempting to exit autopilot) the ui unfroze and I was able to exit autopilot.

On 1/17/2010, at 12:12pm, I departed my house in norwell. After 1. 65 miles, between 99 forest Ave and river street (approximately 50 feet from river street), I released my foot from the friction brake, and the car accelerated on its own toward river street. I put my foot back onto the friction brake, and it stopped. The car was not in auto-pilot mode. I am not aware of cruise control being on. In any case, if it was on, I did not put it on on purpose, and further, it should not have been on since I had my foot on the friction brake pedal just before the event. Enclosed is an image of my trip log showing that my drive started at 12:12pm. Also enclosed is a map showing that it was 1. 65 miles from the start of my drive. I do not have dash-cam footage of this since more than one hour has passed and I did not manually tag it when it occurred because I did not know of an investigation at that time.

When on cruise control or autopilot, car stops abruptly going from 65 mph on the highway to 38 mph before I can override and take control. There is no apparent reason. This happens on a clear open highway.

I own a 2018 Tesla Model 3 mid-range (non-autopilot, non-self-driving, software update v10. 2 - 2019. 40. 50. 7). I experienced a cruise control related safety defect on my non-self-driving, non- autopilot Tesla Model 3 several times since 2019. 40. 2. 1 update. First time it happened at highway speeds. I was going 60-65mph with no cars in front of me. I set the cruise control, let my foot off of the accelerator expecting the cruise control to active like it always had in the past. Suddenly, instead of maintaining the speed it was set at it, the car slowed down with full regenerative braking to below 50mph while still indicating the set speed on the display. I have had the car for over a year (purchased in December 2018) and use car with the cruise control more or less daily. The issue never appeared until after the 2019. 40. 2. 1 update. I was away from home when the update was installed, so I didn't actually start experiencing the issue until January 6, 2020 when I resumed my daily commute. The most recent time it happened, I was actually on my way to the Tesla service center in bellevue wa for an unrelated service appointment. In the this instance, I was turning right onto a four lane, non-divided surface street and accelerating from a stoplight. I remember accelerating to 33mph and seeing the user interface feedback (black circle around the set speed) as I activated cruise control. Before I could react, the car had slowed to about 20mph, while the user interface indicated that the cruise control was still active at 33mph. I was going up a moderate hill at time. The uphill combined with the full regenerative braking effect made me feel unsafe to say the least. I felt fortunate that there were no cars following closely behind me.

Driving in freeway fast lane in light traffic at 10:30 am on overcast morning with Tesla adaptive cruise control set for 70 mph and 4-car following distance. The car in front moved 1 lane to the right leaving no cars ahead. My car accelerated gently to 70 and then as I approached an overpass the car suddenly braked (or went to regeneration) and slowed instantly to about 40 mph when I was able to apply the accelerator and return to surrounding traffic speed and move right to the next lane and recovered from the shock and surprise of what other Tesla owners refer to as "phanton braking". I was fortunate that no other cars weren't following me or they likely would have crashed in the back of my car. I spoke with other Tesla owners who report the same random, surprise, powerful braking when approaching overpasses.

When in cruise control mode and a vehicle crosses my traffic lane far enough away to pose no hazard to me, my car slows very suddenly. This slowing for no apparent reason puts me in danger of being rear-ended by following traffic. A similar slow down happens if the car in front of me makes a right turn onto a side street and my cars slows dramatically even if there is no reason to brake; again creating a danger of rear end collision.

In order to cancel cruise control or autopilot in a Tesla Model 3, the primary mechanism is to push the right stalk upwards as far as it will go. However, pushing the same stalk upwards only part of the way will cause the car to shift into neutral. This can cause a driver to put the car into neutral while it is underway. This is especially dangerous in a Tesla because if the car is in neutral regenerative breaking is disabled and it is the common driving habit to use regenerative breaking as the primary braking mechanism. Essentially, a driver can accidentally make the car unable to accelerate and unable to use primary braking when in motion. In addition, there is no audible alert that the car has been shifted to neutral and only a very small visible change to the touchscreen. I alerted Tesla to this issue in August of 2018 and there has been no change to the car's behavior since then, despite numerous over the air software updates.

On 04/13/2019 the car abrupt stopped in the middle of the road while I drove it along northbond santa rita road in pleasanton CA. . Cars coming from behind had to make urgent braking or lane change to avoid hitting us. My young child was crying in horror, and we have no way to get ourself to safety with the car totally unable to move. We called 911, and local police was dispatch to help other card avoiding hitting us, while we waiting for tow truck to arrive. The car was unresponsive for about 20 minutes, with the display showing messages: "unable to drive, pull over to safety. Car shutting down". The car resumed operational after about 20 minutes, without any noticeable change. I drove the car to nearest service center (pleasanton CA). After a few days, I was contact by the service center stating the car can be picked up, while nothing was done to fix the issue. Their official invoice states: "this is currently scheduled to be fixed in 2019. 20, but the customer can continue driving. If it happens again (seems unlikely), they can just get out of the car and get back in to resume operation. ". I pointed to Tesla service representative that their recommended solution is unacceptable - just like what happened to us already - it would be illegal and unsafe to exit the vehicle if it stops in the middle of highway, with no chance to pull over even to the curb. The Tesla representative brought an engineer to help "explain" the information, when he mentioned that this issue is a known characteristic related to use of cruise control. And the engineer said he would personally be ok to drive the car without using cruise control. I asked if that means the cruise control is not safe, they said it would be my own judgment. I think this is a significant safety hazard Tesla is intentionally ignoring and need thorough investigation.

My Tesla Model 3 has a defect with autopilot sensors and sound. When on autopilot (adaptive cruise control), the sensors can sometimes freeze up and or fail, causing autopilot to cease functioning and issue an audio alert. However, system sound (blinkers, notification alert system) sometimes fails, thus preventing the autopilot from alerting the driver that it will no longer be breaking and or steering. For example, I am driving using the autopilot cruise control, which is supposed to steer /brake/accelerate for me and instructed to keep eyes on the road, however, when the autopilot stops working as well as the audio notification, the driver will not know that it has failed and the car no longer brakes, thus making it likely to have a collision. I have recorded the flaws and defects and have it on video. This can happen anywhere, on highway or on a regular road. Tesla has been unable to fix the problem.

The contact owns a 2018 Tesla Model 3. While driving with the cruise control set at approximately 67 mph, the vehicle independently accelerated to 75 mph. The failure occurred without warning. The contact was able to disengage the cruise control. A dealer was not contacted. The manufacturer was contacted and an engineer was sent to diagnose the vehicle. The engineer was unable to provide a cause for the independent acceleration. The contact stated that the failure recurred several times. The vehicle was not repaired. The approximate failure mileage was 4,000. Consumer stated vehicle either slows down suddenly or speeds up. This has happened multiple times.
