Adaptive Cruise Control problems of the 2023 Tesla Model X

My 2023 Tesla Model X began experiencing safety-related failures immediately after a Tesla software update. Right after the update, the vehicle’s cameras stopped functioning correctly and gps/navigation also stopped working properly. Since that point, subsequent Tesla software updates have failed to install successfully. Tesla diagnosed the issue as requiring replacement of the hw4 computer at my expense for approximately $4,500 because the vehicle is just outside warranty. I believe this may be a safety defect or a software-induced hardware failure because the malfunction began immediately after Tesla’s software update and affects safety-relevant vehicle functions, including camera-related visibility systems and vehicle localization. My VIN does not show an open recall, but this vehicle previously received completed Tesla software recall remedies related to camera/hw4 issues. I am filing this complaint because Tesla should investigate whether this failure is related to a broader hw4 defect pattern, software update defect, or inadequate recall scope. I am requesting investigation of failures involving camera function, gps malfunction, and repeated software update failure after an over-the-air Tesla update.

My 2023 Tesla Model X suffers from severe, intermittent safety system failures. Specifically, the automatic emergency braking and steering assist randomly become unavailable while driving. Tesla service refuses to repair this, claiming they are "unable to replicate" the intermittent alerts. However, the vehicle's history proves severe safety flaws: Tesla previously had to replace the entire steering wheel assembly and the driver's seat belt lap pretensioner due to failures, and had to recalibrate the forward adas camera because it went out of spec causing autopilot failures. These unresolved, randomly occurring defects pose a severe crash hazard that Tesla is ignoring.

Fsd hw3 is so f ing dangerous. It’s tried to kill me many times. It forces lane charge or a jerking wheel wrestling disengage or swerve.

Issue description gps freeze: the navigation system remains stuck at one location even when the vehicle is moving. Park assist not available. Fsd not available. Rear camera shows black screen, completely disabling reverse visibility. These issues occur intermittently, often lasting for days, and then resolve themselves unexpectedly. Unfortunately, when scheduling service, the problem often disappears by the appointment date, making diagnosis inconsistent. However, the failures have already occurred more than three times, and each time they severely impact both safety and usability. Safety concerns lack of rear camera visibility creates a direct safety hazard during reversing. Disabled park assist and fsd compromise Tesla’s advertised safety features. Gps malfunction affects navigation and system reliability.

The primary issues are: the vehicle consistently chooses the wrong lane and drifts across yellow lines. The fsd visualization fails to correctly distinguish road markings, lanes, and turning arrows, causing them to move erratically on the display. The car attempts to merge into lanes that appear in the visualization but do not exist on the road. The vehicle attempts to merge into lanes that are ending, without recognizing the lane-ending markers. My service history for this single, unresolved issue is as follows: June 12, 2025 (invoice #3000s0013397552): I brought the vehicle in because autopilot was incorrectly detecting lanes. The service team diagnosed "severe hazing over forward facing cameras," cleaned them, and returned the car to me. The problem was not fixed. July 1, 2025 (invoice #3000s0013588350): I returned for the same issue, stating that the fsd was driving over yellow lines and not recognizing traffic patterns. The diagnosis was changed to a bad alignment; service notes indicate "multiple angles out of specification". A four-wheel alignment was performed, and I was assured the issue was resolved. July 10, 2025 (invoice #3000s0013675264): on my third visit for this issue, the service team verified that the autopilot visualization showed "random turn lane markings". However, I was told this behavior was "considered normal at this time" and would improve with future firmware updates. The "correction" was listed as "remote - education". July 28, 2025 (invoice #3000s0013834479): I returned for a fourth time, explaining that the problems persisted and were a safety concern. I noted that the car had recently tried to merge past a solid yellow line into the shoulder. The service team acknowledged the issue but concluded it is an "issue with v13 due its design" and that "no repairs are recommended for this concern". The assertion that this is a "known characteristic" is unacceptable. The fsd and autopilot features are now unusable and unpredictable.

Episode #2 'near-death-experience" Tuesday[xxx] Tesla Model X "auto steer" abruptly stopped on [xxx] between 1. 10pm - 1. 15pm sent a message to Tesla around 1. 30pm, exactly the same scenario happened on [xxx]. Coming from [xxx] going to [xxx] , after 10-15 seconds, car stopped abruptly. I do not know what happened and still shaken from episode #1, this incident happened with in 2 weeks apart. After Tesla's review, it was noted that autopilot was not active at 1. 30pm. Tesla can't do anything about this incident, as it is under beta version and it is the responsibility of the driver to be aware of such situations and should take full control of the vehicle. At that time in this situation, what control I have to take immediate control of when car stopped abruptly. Luckily no vehicles were coming behind and survived second time. Laptop screen blank, pressed gas pedal, breaks and after 30-45 seconds, laptop screen started showing up on the left side panel and quickly drove from the ramp. Basically malfunction of the software and/or a glitch caused car to stop abruptly. Now. We are shaken and worried what to do and go to work and do other chores. We have two Tesla and we are totally lost, now what to do and what options to choose for driving. Based on details posted on internet and number of complaints filed, it looks like that no action has been taken. What are the next steps from Tesla's perspective and NHTSA? f in the last couple of years, more than 1500 hundred complaints have been filed, fatal accidents and people died. Your help is much appreciated so that more lives could be saved, information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Episode # 1: Sunday, [xxx] near-death-experience 2 times in 2 weeks while driving Tesla Model X 2023 with fsd. Both myself and wife were travelling and coming from toronto to lake george, NJ all of a sudden car stopped in the middle of the highway. Laptop screen was blank. In the mean time, turned on the emergency light. After a minute or so, white ute came (white) color came behind us with in less than a minute came from behind but he was able to steer on the left, honked couple of times and drove. I started panicking and do not know what to do and kept on saying what happened, what happened,,. . . . And at the same time, my wife asked me to pull car aside quickly otherwise someone is coming from behind is going to hit and that is going to be the end of our life (die) in a crash. Somehow started pedalling gas, break and then noticed laptop screen lightning up and quickly put the car in drive and pulled the car on the right hand side (extreme right) and no service lane. Pulled the car partially on road and partially on the road. Reached lake george late evening and stayed in sleep in & suites, queensbury, stayed over night, Monday and left sleep in on on Tuesday, [xxx]. I just drove couple of miles and was not feeling and was looking unstable and wife did not let me drive all the way from lake george to new jersey. As we parked our car at quick chek for a short break for few minutes. She noticed that instead reversing car from the car park and put car in drive and immediately applied breaks and at that time she did not let me drive. As soon as we reached back and went straight to our son's house and as our son is a dr. , and when told him about the episode he took me straight to jefferson's er worrying that I may have small strokes. Emergency admitted me in the hospital and started diagnostics e. G. , ctc, mri and other blood tests. Next day they released from the hospital and referred for a followup to neuro dr. Next day reported to Tesla. Information redacted pursuant to the freedom of information act (foia),.

Issue is with Tesla full self driving subscription for $199/month and is available for inspection. No warnings or symptoms were indicated. The vehicle recommended I re-enable the service every time the vehicle restarted after it was shut off. Tesla's phone support stated the following is normal expected behavior, so an inspection isn't needed: 1. Automatically changed lanes on interstate into the space occupied by another vehicle multiple times. Thankfully, crashes were avoided by attentive drivers of involved vehicles. 2. Confused "40 mph minimum speed" signs for speed limit, resulting in over 30 instances were speed was drastically and suddenly reduced, without warning, every time the sign appeared. 3. Automatically changed lanes on interstate from rightmost lane to center lane despite no traffic present. This seems to be a default behavior that cannot be adjusted. 4. Disabled cruise control and lane keeping assist when driver overrode automated systems (accelerated, braked, manually adjusted steering) to avoid a crash. Kept these systems disabled as a punishment until driver parked car and restarted.

The contact owns a 2023 Tesla Model X. The contact stated that while driving 70 mph with the cruise control feature activated, the braking system erroneously activated causing the vehicle to abruptly stop in the middle of the highway. During the failure, there were no other vehicles or objects nearby. After shifting into park, the contact was able to restart the vehicle and continued driving. The cause of the failure was not yet determined. The local dealer was contacted. The manufacturer was not yet notified of the failure. The failure mileage was 4,200.

The brake pedal feels off due to low brake fluid.

Using Tesla autopilot I was passing a semi truck on ohio turnpike and as I was right next to the semi truck my Tesla suddenly started to flash red warning light and make a loud squealing sound and began to rapidly decelerate. Luckily no one was right behind us or likely a rear collision would have occurred. The semi truck was a little closer than normal to me but was still within its lane. This happened twice that day so I stopped using autopilot as it was dangerous and very frightening to me and my passenger.
