2023 Tesla Model X Driver Assist & ADAS Problems

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.

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

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

Autopilot full self driving is making dangerous mistakes and being disabled when you still have your hands on wheel and or looking at road it’s a safety system I paid for and it’s illegal for Tesla to disable it and not fix it

2023 Tesla Model X repeatedly and frequently provides distracting false lane departure warning. A sudden loud noise is generated and the display flashes red. However there is no lane departure occurring when this warning is being generated. Has happened over 20 times in the last 2 to 3 months. Display additionally states "corrective steering applied", however there is no force in the steering wheel. Tesla states this is by design.

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.

UNINTENDED ACCELERATION WHILE DRIVING AT A SLOWER SPEED. THE CAR SUDDENLY SPED UP WHICH WAS VERY ALARMING. I HAD TO HIT THE BRAKE TO CAUSE IT TO SLOW DOWN. IT HAPPENED ONCE DURING A 4 MILE TRIP. MY SPOUSE HAD REPORTED A SIMILAR EXPERIENCE EARLIER IN THE EVENING. ALSO MANY FUNCTIONS LIKE PARK ASSIST, TRACTION CONTROL ETC SEEMED TO BE AUTOMATICALLY DISENGAGING

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.

Subject: Urgent ADAS Issue: UI_a114 Error in Teslas with EAP/FSD in East Oahu I'm reporting a critical, location-specific safety concern affecting Teslas with Enhanced Autopilot or Full Self-Driving in East Oahu, particularly when heading westbound. This widespread issue, known as error UI_a114, disables all Advanced Driver Assistance Systems (ADAS) without warning. It impacts essential safety features, such as Adaptive Cruise Control, Lane Keeping, and Emergency Braking, presenting significant risks. Tesla Support in Honolulu acknowledges this as a multi-year issue among East Oahu Tesla owners with EAP/FSD, regardless of activation status. This suggests a software-related problem or environmental interaction unique to this region, necessitating urgent investigation and resolution to ensure driver and public safety. Further details are provided in the attached PDF. Your attention and action on this matter are crucial.

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.

1.Tesla failed to adequately warn us that the 6 sensors in the front and back of the 2023 Model have been removed. Comment from Tesla Collision Center team in Carlsbad: "We both understand the calibration issue won’t be fixed overnight. A program should be in place to educate customers on the change from sensors to cameras." 2. Objects and images in the rear camera are much closer than they appear and the camera sensors do not work properly. Where was this warning when we bought this car? From Jared's Tesla Service report: "There are certain feature limitations which can trigger warning messages and cause some inaccuracies when using this feature. Service Engineering is aware of these issues and is working towards implementing improvements via future firmware updates." 3. As a result of Tesla's failure to warn us, I relied on the rear camera and camera "sensors" and backed into the corner of my neighbor's open garage causing $6,322 in damage.

I have a 2019 Tesla model 3 with ultrasonic sensors and the parking assist system is great. I always feel like I can trust the system and the reported distances. My 2023 Tesla model x has no ultrasonic sensors and the parking assist system is terrible. So many false positives and false negatives that I just ignore the system. I have to park just by my own eyes and judgement. This puts my own car, other cars and private property at increased risks of collisions.
