What 434 owners told NHTSA about the 2020 Tesla Model 3 Bev

On July 11 at approximately 6:47 a.m., I was operating my Tesla Model 3 on Interstate 65 in Hart County, Kentucky, with Full Self-Driving (FSD) engaged during normal highway travel. Approximately one hour earlier, I had departed a highway rest area after sleeping from the previous day’s travel. Rain developed during the trip, but I observed adequate visibility, apparent roadway traction, and I was not impaired. I was traveling in the far-right lane of a three-lane interstate. The posted speed limit was approximately 70 mph; however, FSD limited the vehicle to approximately 65 mph and displayed warnings indicating that the higher speed was unavailable. While FSD remained engaged, the system initiated a lane change from the far-right lane into the center lane. After entering the center lane, the vehicle began displaying repeated warning messages and FSD disengaged multiple times. I attempted to locate settings related to the warnings on the touchscreen but could not identify an available adjustment. During the third disengagement, I perceived that the vehicle continued braking without releasing while steering resistance increased significantly. The steering wheel then rotated abruptly, and I was unable to regain normal directional control before the vehicle departed its intended travel path and struck a concrete median. The collision caused personal injuries and substantial vehicle damage. I have not been able to reproduce the condition. The incident was investigated by the Kentucky State Police. Based on the sequence of repeated FSD warnings, disengagements, continued braking, and abrupt steering behavior, I believe this event warrants investigation. I request that NHTSA review the vehicle’s Full Self-Driving logs, telemetry, Event Data Recorder (EDR) data, steering and braking commands, diagnostic records, and software history to determine whether a vehicle or software malfunction contributed to the collision.

The newer versions of FSD do not allow driver control of the max speed. The current versions allow you to set a maximum speed with a scroll wheel on the steering wheel.

Incident #1 Vehicle sitting at a red light. After several seconds the vehicle operating under Tesla FSD suddenly started to drive as if the light had turned green, which it had not. I stopped it immediately. Incident #2 Vehicle was stopped a t a red light and started forward again as it the light had changed but had not. I noticed a flashing red light at the next intersection a few hundred feet away. So, I went around the block and tried again and it behaved the same. After a few seconds it started to go again. There was not another light near where the first incident occurred.

Vehicle must have thought a shadow line in the road from a bridge indicated a wall I was about to hit, as it slammed on the breaks in the middle of the freeway. Car behind had to swerve to avoid. On the same trip, several nags of 'keep eyes on the road' were incorrect, as my eyes were directly on the road, but phone was in hand functioning as a microphone taking voice memos. Car proceeded to shut itself down while in the middle of the freeway, causing me to go slower than traffic and put me in danger as cars behind me had to swerve or lane change to avoid me as I tried to pull off to the shoulder. These forced shutdowns from incorrect 'nag fails' are causing safety issues. Nag failures should not forcibly shut the car down. Not sure if this is being enforced by NHTSA, or why Tesla is choosing to disable their auto steer or FSD when drivers are detected to be failing nags - nags should be there to help drivers, and potentially the nag data/cab video can be used after the fact should a user failing nags be involved in an accident for insurance dispute resolution, but shutting the cars down themselves is causing issues.

I am filing a complaint regarding a serious safety issue with my 2020 Tesla Model 3 Standard Range Plus. While driving on the freeway, the car displayed a “Power Limited - OK to Drive” message, followed by “Power Reduced,” and then automatically limited my speed to 60 mph. This happened unexpectedly on a busy freeway, nearly causing an accident with a car behind me. The message advised that “exiting and re-entering the vehicle may restore operations.” I took the freeway exit and exited the car, re-entered, and resumed driving, but the error returned, reducing my speed further to 58 mph, and at one point, down to 7 mph. This behavior makes the car unsafe for freeway driving, as the speed can drop suddenly, putting me at risk of a collision. This issue persists on city roads as well, with speed reductions happening within a mile of driving, restricting the speed anywhere between 7-60 mph. I scheduled a service appointment with Tesla on 10/12/2024, but the earliest available date is 11/1/2024. I contacted Tesla’s customer service to prioritize my appointment or perform a remote diagnosis, but they refused to accommodate my request. During my own online research, I found that the car log indicates a “RearDrive Inverter Sensor” detecting high temperatures, likely causing the speed restrictions, along with a non-functional powertrain pump. Although my car is under an 8-year warranty for the battery and drive unit, Tesla has sent me a pre-approval bill for the upcoming service, making me concerned they may try to classify these issues as non-warranty and charge me hefty amounts for repairs. Currently, I cannot safely use my vehicle, especially on freeways, and I have no other repair options outside of Tesla. This ongoing issue is urgent and impacts my safety and ability to drive the car reliably.

The contact owns a 2020 Tesla Model 3. The contact stated that on several occasions while driving with the cruise control feature activated at various speeds, the brakes applied inadvertently. The contact also stated that the cruise control feature failed to operate as intended after dark, after deactivating inadvertently. Additionally, the contact stated that the front and rear cameras displayed phantom images and failed to work as intended. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was unknown.

I took delivery of this Tesla Model 3 last month and have been using it often for my commute. Tesla’s “Traffic Aware Cruise Control” is dangerous and has put my life at risk multiple times now when driving on the highway at night. It slams on the brakes as if it is about to crash when nothing is ahead. It also slammed the brakes when passing a semi truck that was accelerating from being stopped on the shoulder. If anyone was behind me, they would have crashed into me. This “phantom braking” only happens at night. I would disable it immediately but it is not able to be disabled! This is the most frustrating part. I have a long commute on the interstate at night and really need cruise control, and now I am constantly worried when commuting that the car will slam the brakes. The fact that I can’t revert to an old fashioned cruise control with no sensors and no cameras is absurd and extremely dangerous. What component or system failed or malfunctioned, and is it available for inspection upon request? I don’t believe anything “failed”. I believe Tesla’s software is not ready for the real world and this “traffic aware cruise control” should be a beta feature that drivers can use at their own risk. How was your safety or the safety of others put at risk? Unexpected, random slamming of the brakes at highway specs on the interstate at night. In all situations that the “phantom braking” has happened, I would have been rear ended if someone was following behind me. Has the problem been reproduced or confirmed by a dealer or independent service center? No Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? No, as there has been no crash yet Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? No warnings, no messages, nothing. Just sudden braking when using “traffic aware cruise control”.

While operating TACC with lane keeping assist, I experienced multiple iterations of phantom braking when the road and weather was clear ahead. This phantom braking could potentially cause other drivers to collide with the vehicle that unexpectedly braked in the middle of the highway. This problem has been a common issue with multiple people taking their cars to the service center to get checked out with no problem identified. There are no warning lights or indicators that the Tesla is going to phantom brake on the highway. Recommend having Tesla provide information regarding this phantom braking.

We had Model 3 with instance of unintended acceleration at the gate of a parking lot. This car was bought in May 2020. On December 6, 2020, she was on the way out of the parking gate and suddenly the car accelerated, hitting the side wall of the gate. The car flew over a two-way street, resulting in a compound fracture of her right hip requiring internal fixation and transfusion. The vehicle was inspected by the police. There were no warning lamps, messages, or other symptoms prior to failure.

I was already situated in the left turn lane on a two way city street, slowing down, and about to come to a full stop before making a U turn when I felt a surge in power before the car picked up, accelerated uncontrollably, and launched forward. In front of the turn is a raised cemented median strip divider where the car hit and went on top of it. Instinctively, I just held on to the steering wheel firmly to keep the car straight so that it will stay on (top) and within the divider and not veering to the right or left and running onto incoming traffics on both sides of the street. The car came to a stop after coming off the other end of the divider (approximately 100 ft) and ended on one of the lane from the opposite traffic. Thankfully there were no cars on that lane at the time and I was able to sluggishly drive the car safely into an adjacent parking lot. I, as well as other could have been seriously injured or killed. All wheels and tires are visibly damaged and possibly the underside as well. The car is in a body repair shop and waiting for inspection at this time. I already reported the incident to my insurance and Tesla companies. All inspections and reports are pending at this time. There was no police report since there was no collision or bodily injuries. There were no warning signs, signals, messages, or symptoms from the car or from Tesla before the incident. The car 12V battery was changed 3 months prior by Tesla Service Center. This is my first encounter with this sort of problem.

I've had the car since December 2019. The car will "phantom brake" when the autopilot adaptive cruise control is on. This happens intermittently, ~1 time per month on my normal commute. I will be going along, cruise set to 75 and out of nowhere it'll slam on the brakes and lose 10 MPH in a second before I can take over. This occurs with absolutely no traffic or reason, it'll be an empty highway and it does it. I drive with my foot over the accelerator so I can floor it to override the car. This is the exact opposite reaction I would think that someone should have to do with a safety feature. Tesla tells me the system is working fine, but random brake checks on the highway should never be normal. I don't understand how this system was approved to operated by the government.

On 9/3/23 we were traveling from Moab UT to Green River UT and the cruise control was engaged at highway speeds. We were not using the "Autopilot" functionality. Without warning, the car suddenly decelerated under what felt like hard braking. There was no warning immediately before the hard braking started and the car had no warning indicators of any kind either before or after the incidents. The hard deceleration happened at least four times. One of those times a raven flew up from the road, but the other times there was nothing in the road. At least three of the incidents occurred on highway 6 traveling north. The last time it occurred was on I-70 westbound after we stopped the cars and cleaned all the cameras and ensured there was no debris on the front bumper which could cause issues with the forward-looking radar. We lost confidence in the cruise control feature and did not enable it for the rest of the trip. This is a safety issue because the car does not just reduce speed, it feels like it is braking hard or perhaps full regeneration of the battery. Either way, on these 2-lane highways, there are often situations when other drivers are driving too close to the rear bumper and a sudden, inexplicable hard braking is very likely to cause collision. A collision at these speeds could push the car into oncoming traffic, leading to fatalities. We asked Tesla service to look into the issue, and said there is likely footage of at least one of the events (because I honked the horn to start recording). The Tesla service person gave several reasons why it deceleration may occur, but Tesla is neither reviewing the footage, nor taking action to remedy the issue. They said "Our remote diagnostics has confirmed the vehicle hardware is operating as expected and there are no repairs the service team can make in regards to this." With service unable to make a fix to the car, this problem remains unresolved and we have lost confidence in cruise control.

While driving on the freeway, my 2020 Model 3 “phantom braked” multiple times while using the cruise control. No autopilot for lane keeping assistance. There were no cars in front of me or any hazards. The pavement was pretty new. I was using this feature earlier in the trip with no issues then it started all the sudden with multiple incidents in a short amount of time.

Phantom Braking occurred almost 40 times on our recent trip from Northern NV to California and return. We left on July 16 and returned on July 21. Our route was from Minden NV to Las Vegas on Highway 95 and then onto Temecula CA on Highway 15 and 215. The return trip was on Highway 15 to CA 138 to Highway 14 to Highway 395. All travel was during daylight hours. Sometimes phantom braking was so severe, the deceleration cause us to be thrown forward towards the dashboard. We wore seat belts to prevent hitting the dashboard. This also happened on a similar trip in 2022 and was reported to Tesla and were told that nothing could be done. The current software version is 2023.20.9

Unexpected Phantom Braking was experienced in this vehicle on a sunny day at mid day on I-30 going East through Arlington. The car was operating on Traffic Aware Cruise Control. Travelling at approx 70mph the vehicle suddenly slowed very quickly below 50 mph before I interceded to resume control of the accelerator to resume my speed before I was rear ended. This occured as I was approaching an overpass in my middle lane.

Had cruise control on and “phantom braking” occurred about 10 times on a 22hr trip from California to Oklahoma. Very scary. Car went from 80 to about 40mph in seconds. How is this even possible for Tesla to have these vehicles on the road? I’ve only had the car for 2 weeks.

NHTSA ODI 11529898

I was driving from indio,ca to Orinda,ca on interstate 10-210-5 north and the vehicle had at least 6 phantom braking events when the car was in cruise control and one event the auto pilot was on. There was clearly nothing front of me. This is so dangerous and there will be a bad accident if it isn’t fixed. Please have Tesla fix this.

on July 19,2022, when I was driving on driveway, at less than 5 miles, I tried to stop to drop my wife and applied brake. Instead of brake, due to computer mal function, it accelerated & hit the garage door, broke the garage door, door fell on the car parked in the garage, damaged that car,and tesla automatically reversed. while reversing brake wasn't working too so I tried to put in drive & brake still was not working so to stop the car for safety, I hit the curb in my front yard All airbags were deloyed, inuring both of us. All doors were locked & we couldn't open any of them. We could open windshield. We shouted HELP and my neighbor came & open the door from outside so we could get out otherwise we both could be dead inside the car

The car had unintended acceleration. I was driving and suddenly it sped up really fast and I needed to slam on the brakes. This was on a residential street so it was really dangerous. This happened once before, on a highway. Both times this happened, I was touching the wipers controls. I have no idea if it’s connected or coincidence.
