Assist Problems of Tesla Model 3 - part 1

Speed profiles do not allow safe operation of the vehicle. Changes in speed profiles result in unsafe behavior. Standard speed profile regularly results in speed up to 73+ in a 55mph zone being selected by the vehicle. Chill mode results in speeds of 58 when traffic is traveling at 65mph. Switching profiles from standard to chill results in a rapid deceleration within the lane leading to problems with traffic behind the vehicle. In active school zones, system regularly does not acknowledge school zone speed limit and proceeds at 25-30mph in a 15 mph school zone even on sloth profile. European fsd has a max speed setting that allows these problems to be prevented, but it is missing as a critical safety feature in the us version of fsd 14.

Tesla fsd on hw3 vehicles has become very unstable. Users complain the car ping pongs within the lane and occasionally will steer onto the left or opposite lane. This seems to have happened after a recent update between Feb/March 2026. Growing reports of the same issue reported on reddit. Ping pong Tesla fsd sources: r/teslafsd, r/teslalounge, r/teslasupport Tesla fsd ping pong effect software updates recent updates: many users have reported that the ping-pong effect started after recent software updates, particularly 2026. 8. 6 and 2026. 14. 3.

I purchased the full self-driving (fsd) package for approximately $10,000 on my 2022 Tesla Model 3 long range awd. Tesla marketed fsd as a feature that would enable autonomous driving capabilities including navigate on autopilot, auto lane change, autopark, summon, and city street driving - all to be delivered via software updates. Tesla has since confirmed my vehicle's hw3 (hardware 3. 0) computer cannot support fsd as advertised. There is no hardware upgrade path. The fsd transfer program that allowed owners to move their purchase to a new vehicle ended March 31, 2026 with no accommodation for affected owners. The system regularly fails to perform as advertised. It requires constant human supervision despite being sold as "full self-driving. " I have sent three formal complaints to Tesla's executive team (may 7, 8, and 12, 2026) with zero response. Tesla's own support chatbot confirmed I am not eligible for fsd transfer.

When using fsd in "chill" mode the car attempted to cross over into oncoming lane on a two lane highway. There were no oncoming cars and I overrode the car almost immediately. The car has not been inspected by anybody. No warning light, messages or other symptoms. I have a video of the incident for a viofo dashcam installed in the car.

While using Tesla's full self-driving (supervised) software on the pacific coast highway (pch) and other highways, the vehicle’s automated steering system repeatedly malfunctions by failing to maintain lane centering. Specifically, the car drifts or actively steers across double yellow lines into the lane of oncoming traffic. This issue is a persistent failure of the advanced driver assistance system (adas) and lane keeping assistance. The vehicle has attempted this maneuver multiple times at [approximate speed, e. G. , 40-60 mph], requiring immediate and forceful manual steering intervention to avoid head-on collisions with oncoming vehicles. The system provides no warning chimes, error messages, or "take over immediately" alerts prior to crossing the lines; it appears to perceive the oncoming lane as a valid path or fails to recognize the double yellow boundary entirely. This has occurred during [mention conditions: e. G. , bright daylight with high glare / night time]. The vehicle is equipped with hardware 3. 0 (hw3). I believe the 1. 2-megapixel camera suite or the processing power of the hw3 computer is insufficient to safely navigate the geometry of the pch or any roads within mountains/hills. I have attempted to "clear calibration" and performed system resets, but the life-threatening behavior persists. The vehicle and its internal data logs are available for inspection. I have also sent "bug reports" via voice command to the manufacturer immediately following these near-miss events.

I purchased a 2024 Tesla Model 3 a little over a year ago. Recently, and after an update, myself, and other drivers in my life, noticed the self-driving feature was malfunctioning - to the point I used the audio reporting feature to report this problem twice to Tesla. The car would veer off the road when flasing lights appeared and would jerk suddenly for no reason when it thought there was a obstruction in the road (sticks, plastic bags, etc. ). Last month this malfunction has caused an accident, and my car has been totaled, my insurance will not cover it, and I have been advised by two separate attorneys to sue. This has been litigated in court with lawsuits against Tesla (see benavides v. Tesla; see also in Tesla advanced driver assistance systems litigation). I had notified telsa twice of this issue, the car left the lane and did not notice a concrete barrier on the left side going north on I-95 in or around broward county. To my knowledge no one has inspected the car. I was not warned that this car would cause an accident, the problem first appeared when I reported the issue using the voice reporting feature around November 2025. It is currently located at a tow facility in broward county, FL and can be inspected there.

The steering was hard to turn, and the fully supervised driving mode didn't work. This has happened twice, and both times the issue went away on its own after a few minutes. I performed a soft reset both times, but it did not resolve the issue. The first time, the steering was very heavy, I. E. , hard to turn. The second time was less difficult, but in both cases, fsd (full self-driving) did not function. General guideline questions: 1. The steering system malfunctioned. The car is available for inspection. 2. The car was very difficult to drive. I was able to turn the wheel, but I won't let my wife drive it. 3. No. The nearest service center is 90 miles away, and so far, they want me to bring the car to them. I am still working to resolve this, as I believe this issue requires mobile service. 4. No inspections have been done. 5. Yes. An alert message on the main display stated: "alerts - steering & braking - steering assist reduced/steering may require increased effort. ".

Tesla full self driving software malfunctioned and turned into oncoming traffic lanes instead of crossing over to the correct opposite side of the roadway. This occurred after getting off a on ramp in ukiah, California around 2am Nov 15, 2025. This could have put others in serious danger if there were cars coming in the oncoming lanes heading in the different direction. The problem has not been reproduced by a dealer or other entity. Yet this has happened to other Tesla drivers as well using fsd as you are probably already aware. No inspection and it was sudden and unexpected.

The Tesla fsd performed in a dangerous way. It came into a left lane when a speeding truck was in the lane and nearly hit my car. This occurred on Nov 12 around 5:30 pm near floor and decor at kolb and broadway intersection in tucson az. I engaged fsd to return home in oro valley. First the car did not follow straight path going from the parking store lot to make a right trun and enter kolb road. It made right turn and left turn and then right to kolb road to turn right. It was a busy time in the evening. When an opening was found it entered kolb road and then rapidly zig zagged to change lanes to try to enter left turn lane only on kolb to turn on broadway. In the left most lane, it did not detect a fast approaching truck. The truck honked, and I took control of the car and sped through the intersection to avoid collision.

I was driving on a straight interstate road between 60-70 mph using full-self driving around 4:15pm and there was no traffic in front, behind, or next to me. Suddenly, the car tried to make a sharp right turn that felt like more than an obstacle avoidant move or lane keeping move. I had to grab the wheel even harder than I was (my hands were fortunately on the wheel) and force it back into the lane. If I did not make this intervention, I would've gone off the road and crashed.

On October 17, 2025, while full self-driving (supervised) was engaged, the vehicle made an abrupt, uncommanded steering input to the right, causing a collision with a tunnel wall. This crash appears to be the result of a critical vehicle hardware failure. In the 24 hours prior to the crash, the vehicle logged multiple critical steering errors, including epas3p_a086_dasmia, which indicates the electric power assisted steering system was "missing in action" and not communicating. Furthermore, the vehicle has logged daily, recurring hardware faults for the steering column control module (sccm_a016_hardwareerror) since it was purchased. The uncommanded steering action created an extremely dangerous safety condition resulting in a collision. All stability and traction control faults appeared at the exact moment of impact, not before, indicating the steering system failure was the root cause. The problem has been confirmed by the vehicle's own internal diagnostic logs. The vehicle is available for inspection.

Vehicle self drove took quick into an off ramp and took flight on cattle guard into a pole. The vehicle never attempted to make a emergency stop and no air bags deployed.

The Tesla ran a red light on two separate occasions while in full self driving mode. The first time it went through without me being able to intervene. Given it had done it before, the second time I was able to stop it. Both times occurred at the intersection of [xxx] and [xxx] . It has not done it at other intersections.

Steering rack failure. Steering assist, auto pilot and lane departure prevention failed and would not work properly so this is a safety issue. Manual steering worked fine but the safety and auto pilot functions would no longer function. Paid for Tesla service over $3,000 to replace steering rack and now is working properly. Reporting this as this may happen to others and probably should be a proactive recall on the steering racks so others don't lose these safety features. Maybe related to computer as it failed, worked again and then failed again and was then repaired by Tesla service center.

Component/system involved: advanced driver assistance systems — fsd (supervised)/autosteer (lane keeping assistance) and adaptive cruise control. Possible failure to warn/stop (fcw/aeb). Vehicle and data are available for inspection upon request. I preserved dashcam files and requested Tesla to preserve engineering logs and edr. What happened & safety risk: on Aug 13, 2025 at ~9:30 am pdt on us-101 sb near east palo alto, CA, with fsd (supervised) engaged, the system appeared to misinterpret an exit ramp/gore area as a continuing lane at a highway fork and maintained ~60 mph (posted ~70). As soon as I saw the trajectory was unsafe, I braked and began manual steering takeover, but the vehicle contacted a roadside sign near the gore/shoulder before I could complete the maneuver. I then stopped safely. No other vehicles were struck. Airbags did not deploy. This posed a serious collision risk to me, my passenger, and nearby traffic. Reproduction/confirmation: not reproduced. I have not attempted to reproduce the event. Unknown whether the issue has been reproduced by Tesla or a service center yet. Inspection to date: police responded (report pending). My insurer has opened a claim. I opened a Tesla service request asking to preserve autopilot/fsd engineering logs for the incident window and to coordinate edr extraction; engineering review pending. Vehicle remains drivable. Warnings or symptoms before failure: no audible/visual forward-collision warning was perceived by me and I did not observe automatic emergency braking. No prior warning lamps/messages were noticed before the departure toward the gore. Unknown whether any internal/partial interventions were recorded in logs. . Read more...

Subject: urgent complaint regarding power steering failure in 2019 Tesla Model 3 hello NHTSA, I am writing to file a complaint regarding a very dangerous situation I recently experienced with my 2019 Tesla Model 3. While driving on the freeway at approximately 65 mph, the power steering failed unexpectedly. I struggled significantly to change lanes in order to exit the freeway, and it felt as though my vehicle was going to collide with other cars. After managing to get off the freeway, I nearly hit the guardrail while attempting to turn onto a side street, creating a hazardous situation. I am deeply concerned about the potential consequences; for instance, what if I had struck a pedestrian, or if the car had collided with another vehicle at high speed? I live on a winding mountain road, where I could have easily driven off a cliff. Turning the car off and back on temporarily resolved the issue. However, there are numerous complaints regarding steering rack failures with Tesla vehicles. Tesla has quoted me $2,700. 00 to fix what appears to be a known manufacturing defect. They are aware of this potentially hazardous situation but are not taking responsibility for the repairs. This is a serious safety issue, and I urge Tesla to accept responsibility and cover the repair costs before someone is seriously injured or killed—if such an incident has not already occurred. Please let me know what further actions I can take to facilitate Tesla's resolution of this dangerous problem. Thank you for your attention to this matter. Sincerely,.

I took my car to Tesla service to have 3 tires changed. On the drive home for the service, the car automatically pulled the to right several times with the final time pulling so hard, the car jumped the curb and damaged the car. Speaking with the Tesla service associate after the accident, they admitted that they did not complete alignment of the tires and that the automatic lane correction mechanism uses the alignment to gauge if it should correct or not. Tesla service will not take responsibility for causing the issue.

Curvature assist feature agressively brakes while driving at highway speeds. This is supposed to slow down for curves, but frequently intervenes for straight, clearly marked lanes. Feature cannot be turned off. Drivers behind me have gotten agitated several times for the sudden, harsh braking, and I do not feel comfortable driving this car.

My vehicle is equipped with supervised fsd and has had couple of issued on the intersection of [xxx] and [xxx] in portsmouth, virginia. It seems every time I stop at the light, the system recognizes the red light and stops, but shortly after it wants to keep advancing forward although the light is still red and has not changed. The vehicle has also had a problem staying on lane at light on the intersection of [xxx] and [xxx] in suffolk as it is getting ready to turn left prior to entering the entrance road to [xxx] . The image in the screen is correct and the lines are in place, but the vehicle has trouble staying with in the line and needed to be corrected. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Fsd malfunction, inspection available. Yellow double lines were not recognized around a turn, causing the car to steer towards oncoming traffic. Unknown. Vehicle was declared fully functional by Tesla dealership. No warnings, vehicle had many symptoms prior to the last event in which I decided to service the vehicle. First critical malfunction may 21, 2025.

While making a wide right turn at an intersection I heard three warning beeps before the steering wheel locked. I was unable to correct the steering. When I realized it wasn’t allowing the steering to correct, I began to brake, causing me to drive over a curb, ultimately stopped by a fence and cactus in someone’s yard. This is a huge safety concern, as children could’ve been playing in the yard, or farther up the road where a curve has a 30 foot embankment I could have rolled into. I have scheduled a service appointment with Tesla to have it looked at. I have had this issue occur multiple times before and am sure it can be reproduced.

Tesla fsd incident – exton, PA ([xxx]) just sharing a scary experience I had with Tesla fsd beta yesterday — hoping it reaches the right eyes and helps others stay alert. I was driving on a main road in exton, PA, using fsd with the “avoid highways” option turned on for the first time. This is a route I know well and usually follow using google maps. At one point, fsd turned on the left indicator, and I thought it was taking a regular exit — the road it chose looked like a narrow side street, so I didn’t question it. But within 5 seconds, I realized it had actually taken me into the oncoming traffic lane. It was shocking and totally unexpected. I immediately took over, stopped the car, and when the road was clear, safely steered back into the correct lane. This happened around 3 pm on a bright, sunny day, with normal traffic. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

I have a safety concern regarding Tesla's full self driving (fsd) supervised system. V13. 2. 8 being the latest customer version. Since the update to fsd v13 in December, I have consistently used it on a daily basis. While it performs great on city streets, it consistently caused a serious safety risk on the freeway: it habitually tailgates cars at high speeds of 70-80 mph on the freeway. It does this even when there is no traffic and the other lanes are wide open. I have experienced this on both a Model 3 (2025) and a model y (2024). I am writing this complaint here hoping you will pay attention to it, as despite my best efforts, Tesla has ignored my feedback. I even opened a service ticket about it at one point, and the service tech couldn't care less. Not maintaining proper distance to the cars in front on the freeway puts the passengers at high risk for a rear end collision. If Tesla is to launch an unsupervised version of their fsd system, this problem must be addressed first!.

After installing Tesla ota software update 2024. 45. 32. 15, my vehicle experienced critical system failures. Upon entering the car the next morning, I noticed that all cameras were non-functional, and navigation had completely stopped working. This posed a serious safety concern, as features like autopilot, parking assistance, and basic visibility enhancements (such as rearview camera functionality) were unavailable.

Have to swerve the vehicle back and forth to get the alarm to shut off.

My Tesla was operating in full-self-driving beta when it experienced a sudden uncontrolled accelration event. I was driving on [xxx] at approximatley [xxx] this morning. The road speed limit was 40 mph. The car display was correctly showing that the road speed limit was 40mph. The speed offset in the cars setting was limited to 5 mph max above the speed limit. While the car was driving it suddenly accelerated very hard from approximately 40 mph to over 60mph before I was able to stab the brake pedal and kick the car out of full self driving mode. There were no errors, warnings, or signs that anything was wrong with the car. I have also notified Tesla via the service request function in the Tesla app under the section for "software performance". Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Driver set cruise control has fsd imbedded that causes the vehicle to slow down drastically on its own. The car has brake tested several following vehicles so far. I’ve seen this before many times of other Teslas but thought it was the driver and now I know it was not. This causes a chain reaction of braking and smoking tires. I am positive this has created accidents but the ones involved have no idea how it started many vehicles ahead. The lane keep assist pillar cameras do not work in the dark, this has taken me by surprise already. The phantom braking on highways is awful, it is so bad that I am afraid to drive in the winter. The torque of the wheel sensor is not safe, when auto steer disables it can take you by surprise causing you to swerve into on coming traffic. The car accused me of using a cheat device one time so I decided to try it and surprisingly I found that it is actually much safer than using my body weight. These are extremely unsafe for busy traffic and slippery roads. I have videos showing it and will get more.

I have a 2018 Tesla Model 3 that was involved in an accident on 10/12/2024. It has enhanced autopilot, which was the most advanced version of self driving when I bought the car. It was engaged in "navigate on autopilot" on the freeway. The car was following the freeway as it veered to the left, but then it stopped following the lines and crashed into the side of the freeway. The result of the accident was a total loss on the vehicle. I had shoulder and neck pain that have not required serious medical attention, but it was almost a week of discomfort and difficulty sleeping. My insurance company has deemed the vehicle a total loss and I will have to get a replacement. There were no warning alerts and the vehicle did not recognize that it was leaving the freeway lines. I was not going over the speed limit. The car did not prompt me to take over the vehicle because of danger. It just went straight towards the freeway guardrail. The car is not drivable due to the damage it sustained.

October 12, 2024. I was using the Tesla on autopilot. I was in the far right lane and the freeway was curving to the left. The car was following in the lanes, but then all of a sudden it stopped following the freeway and drove into the right guardrail. There were no alerts by the car. It did not warn to take over the vehicle or attempt to avoid the collision. The car drove directly into the guardrail without warning and was totalled.

Lost power steering suddenly on the road.

Received several "steering assist reduced" alerts when stopped in traffic last week, followed immediately by the failure of the power steering after each alert. Power steering resumed after a soft restart. Tried to make appointment at Tesla service center last Friday to get this addressed, but they said they had no appointments available and would not be able to diagnose my vehicle until today, August 12, 2024. . In the interim, the power steering went out again while on the freeway, forcing me to exit and restart the vehicle again. This is a clear danger to myself and my passengers. After receiving the results of the diagnosis today, they informed me that both the steering rack and harness would need to be replaced at the cost of nearly $5,000. The technician showed me some corrosion in one of the electrical connections where there had been water intrusion. I told him this was surprising since the car is relatively new and it would seem that Tesla would have sealed this connections to resist the relatively dry rainy seasons we experience here in southern California.

The right scroll wheel used to turn on/off adaptive cruise and lane centering doesn't register inputs every time the button is pressed in. This makes turning the system on and off unpredictable and dangerous.

On several occasions, the last being July 19,2024, auto correct on steering took control of my vehicle when no correction was needed. I’ve been taken by surprise and struggled on all occasions to gain full control of the vehicle. In addition, my car is not able to receive the over-air update to address the hood latch recall which leaves me more vulnerable to a catastrophic event. I can not reach a person in service as Tesla pushes every communication through the app. My appointment was pushed out over three weeks and I still have not heard from Tesla to confirm this appointment nor reach out with any concern whatsoever regarding this horrific safety concern.

While driving in the right lane of an interstate using full self driving (supervised) mode (version 12. 3. 6), I was behind a motorcycle that was traveling slower than I. Fsd was gaining on the motorcycle, but failed to move to the passing lane. I had to disengage the system so that the car didn't get too close to, or strike, the motorcycle. I manually moved to the passing lane and reengaged fsd. The car eventually decided to move to the right lane, behind the motorcycle. Again, it was gaining on the motorcycle and got too close, so I once again had to disengage fsd. It seems like the system didn't recognize the motorcycle or didn't recognize that it was traveling than slower than my vehicle.
