Adaptive Cruise Control problems of the 2024 Tesla Model 3

Component/system that failed: Tesla full self-driving (supervised) software version 14. X (2025. 38. X and later). The issue is software-only and remains installed on any vehicle updated to v14. Description of safety defect: fsd v14 deliberately removes the driver’s ability to set or adjust maximum speed offset using the right scroll wheel (feature present in all prior versions including my current v13. 2. 9). As a result, the system routinely exceeds posted speed limits by 5–20 mph with no way for the supervised driver to correct it short of fully disengaging fsd. The vehicle ignores speed-limit signs, relies on inaccurate map data, and follows surrounding traffic speed instead of the legal limit, even in school zones, construction zones, residential areas, and adverse weather. This significantly increases risk of collision, injury, and traffic citations. Reproduced/confirmed: widely reproduced by thousands of owners on Tesla forums, reddit, and x immediately after v14 rollout in late 2025. I have chosen to remain on v13. 2. 9 to avoid this exact defect. Inspected by manufacturer or others: no in-person inspection required; Tesla has full remote log access. Multiple owners have submitted in-car bug reports. Warning lamps/messages: none. The speed-offset control is simply grayed out and non-functional by design in v14. Vehicle available for inspection upon request.

The forward-facing camera on my vehicle repeatedly fogs up inside the sealed camera housing, creating a light to severe haze across the camera lens. This internal fogging obstructs the camera’s view and affects the vehicle’s safety systems that rely on it, including forward collision warning, automatic emergency braking, lane keeping, and adaptive cruise control. The components are available for inspection upon request. This obstruction puts my safety at risk because these systems either disable themselves or operate unpredictably when the camera view is blocked. The issue occurred again this year under normal outdoor temperatures, and the fogging cannot be cleared by the driver or by using defrost or cabin heat. The problem has been confirmed previously by a Tesla service center, where technicians inspected the camera area and told me my vehicle had one of the worst cases they had seen and told me this is a common issue. They attempted a repair, but the issue has returned, making it a recurring defect. No police or insurance representatives have inspected it. During the first occurrence, the vehicle displayed messages indicating that features like autopilot, cruise control, and lane assist were disabled due to camera obstruction. The current recurrence produced visible internal haze over the camera lens and a warning message appeared which I do have that Tesla acknowledges this is an issue and that rather than fixing it, you can bring your car in for expedited cleaning. I have read others stating Tesla changed their windshield design and it doesn't heat up this area properly any longer. This issue has happened in multiple winter seasons and directly affects the proper operation of safety-critical driver assistance systems.

While driving with fsd engaged and set to standard profile, fsd accelerated to 76mph in a 55 zone. This is on software version 14. 1. 4. Unfortunately this new update no longer allows you to set your speed while using fsd, you can only select sloth, chill, standard, hurry, or mad max.

Full self drive 14. 1 removes the max speed setting that allows drivers to control the speed of the vehicle while under computer control, leaving no way to prevent the car from speeding when the speed profiles choose to drive over 28+ mph over the speed limit. The lack of ability to control the speed of the system is fundamentally unsafe by design.

A recent update has caused the vehicle to no longer acknowledge an important speed sign. This was confirmed by another Tesla, it is due to an update. This is unsafe and is capable of allowing the vehicle to travel through town at 75 mph where pedestrians cross the highway. If the camera gets blinded at the wrong time then it will not see people or vehicles as it plows into them. I made Tesla service aware and tried to submit a bug report but Tesla app simply says they are aware that the camera may not always read the signs. However, this was never an issue until a recent update. When are you going to make them liable?.

Recently I had three back to back near miss head on collisions on highway early morning still dark. These three along with a previous near miss the vehicle had zero reaction to the imminent collision with roughly half a second to spare. It happened so fast that I must have let go of the record button as there was no saved video. I am working with lemon law firm and class action firm, get your crap together because these recent accidents reported in az are also your fault for not reacting appropriately to previous complaints.

I am filing an urgent complaint regarding multiple incidents involving my 2024 Tesla Model 3 (VIN: [xxx] ) that caused major safety risks, personal property loss, and serious disruption to my life. [xxx] – while in a left-turn lane with autopilot engaged, the car attempted to go straight. When I took over, the system malfunctioned severely. (photo evidence available) [xxx] – remote support failed; car towed to Tesla upland service center. June 27, 2025 – issued loaner vehicle. July 1, 2025 – Tesla claimed I must pay for repairs. I requested a written evaluation report, but to date it has not been provided. July 20, 2025 – without consent, Tesla remotely locked my vehicle with my personal belongings inside, violating my property rights. Aug 1, 2025 – Tesla promised review and report but refused to unlock my car. Aug 12, 2025 – after 10+ days, still no report. Upland “options” included threats that my locked car in my garage could be deemed stolen, causing severe mental distress. Demands: 1. Full investigation into autopilot failure and handling delays. 2. Immediate delivery of written evaluation report. 3. Accountability for delays, threats, and property rights violations. 4. Compensation for all losses and disruptions caused. Contact: [xxx] I request a written response within 24 hours. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Vehicle: 2024 Tesla Model 3 date of incident: [insert date] location: intersection of [xxx] operating mode: Tesla autopilot (engaged) on the above date, while driving with Tesla autopilot engaged, the vehicle initiated an unexpected and improper right turn at the intersection of [xxx] this maneuver was not indicated in the planned navigation route, nor was it consistent with the legal road markings or signage in the area. The vehicle turned into a clearly marked “do not enter” and “wrong way” zone, without any driver input or confirmation. I attempted to intervene, but the turn happened abruptly and could not be safely overridden in time. This resulted in a collision, vehicle damage, and physical trauma to both occupants — including nausea and vomiting in my wife immediately after impact. Dashcam footage from the right repeater camera confirms the presence of multiple “do not enter” signs visible at the point of the turn. We have requested the Tesla event data recorder (edr) logs to confirm that autopilot was active and that steering input came from the system, not the driver. I am reporting this as a serious safety concern related to Tesla’s autopilot system and its decision-making at intersections. If this had occurred in a busier traffic environment, the result could have been far worse. This type of navigational or perception failure should be investigated immediately. Both occupants are seeking medical treatment and continuing to deal with the emotional and physical aftereffects of this incident. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

While driving from costco in fountain valley to best buy in costa mesa, I was using fsd for the entire route. Everything was running smoothly until we approached south coast drive near the I-405 interchange (costa mesa, CA). At that point, the fsd system incorrectly directed the vehicle to enter a freeway off-ramp, effectively driving into an I-405 freeway exit ramp in the wrong direction. This created a highly dangerous situation, as the ramp was intended for vehicles exiting the freeway, not entering. Fortunately, I was able to take over control of the vehicle and prevent a potential accident, but this was a very close call. Incident details •date: March 21, 2025 •time: between 2:00 – 3:00 pm •location: south coast dr near I-405 on/off-ramps (costa mesa, CA) •route: costco fountain valley ? best buy costa mesa •navigation mode: full self-driving (beta) enabled throughout •conditions: daylight, dry roads, moderate traffic what happened •fsd turned the car onto a road segment that functions as a freeway exit. •the vehicle entered the lane facing oncoming traffic exiting from I-405. •I immediately disengaged fsd and took manual control to correct the situation.

Multiple instances of phantom braking, car will suddenly slam on brakes without any indication of danger or anything to avoid. This has happened at least a dozen times and we are fearful that it will cause an accident. Vehicle will also alert lane departure and attempt to automatically adjust, turn to another lane while in the appropriate lane. Multiple incidents, at least 30 in 6 months of ownership. No collisions as of yet, concerned there could be.

Tesla has told me the ap4 computer has failed in my car which has resulted in them having to replace it. This issue impacts: emergency braking, blind spot detection, lane keep/centering, assisting with parking, automatic high beams and wipers, cruise control/ adaptive cruise control, vehicles built in gps to be stuck at one location every time, has made my touchscreen not automatically brighten or dim, my auto dimming mirrors be too dim in most driving conditions, constantly fail to install system improvements and safety updates, and because my vehicle keeps trying to do this, it has caused increased battery drain as well. This has increased the safety risk of my vehicle tremendously. . . Tesla has not seemed to publicly acknowledge the issue yet either.

The car consistently has phantom braking. The speed will drop around 15 miles of speed immediately. It also will slow on rolling hills and random long turns on cruise control. Most recent date listed.

12/26/2024 around 5-6pm, full self drive abruptly tried to accelerate into the intersection while sitting at a stop light. I stopped it immediately but was very surprised as fsd v13 has been exceedingly reliable and a pleasure to drive. This is the 2nd time this has happened after the holiday update of fsd 2024. 45. 25. 5 (v13. 2. 2). Both times mine was the lead car at the light with no others ahead of me. This behavior has been reported multiple times in social media groups this past week by other fsd users. I entered a Tesla service request but have not heard back other than an automated appointment scheduled at the service center 8 weeks from my request and the incident.

Car randomly breaks or swerves when using cruise control. When there is nothing ahead of me have called Tesla and been told it is called phantom breaking and that it is normal happens multiple times a day, almost causes collisions. Very dangerous.

The front camera that is known as Tesla vision consistently stays fogged up. This creates an issue when using auto-pilot that makes the car beep loudly and disengage auto-pilot putting others at risk if the car disengages and the driver is not quick enough to respond to the the disengagement. After several months of this and the problem does not go away after following Teslas advice per their user manual of pre conditioning the car and DE fogging the windshield for a long period of time, I have scheduled a service appointment. The vehicle I own has not been inspected by Tesla, nor a third party service at the moment. There is no warning when the system will deactivate and I have had it happen several times on corners which is very concerning and scary when in the vehicle.

Using cruise control to go with the flow of traffic the vehicle will slow down for any random flashing lights far away or vehicle in next lane causing all vehicles to slow down unnecessarily. Fsd and beta programming does not belong in driver set cruise control.

While using traffic aware cruise control the vehicle would rapidly decelerate with no warnings of potential collision and with no actual emergency situation existing on the road. In a single trip that spanned both day and night there were three rapid declaration events occurring both when light or dark outside. Vehicle display wouldn't show any messages as to the reason for declaration.

There is a a very dangerous software issue with new Tesla models where there is a 1-2 second lag between when cruise control is disengaged and when it actually disengages. Especially, at high speeds this is dangerous because the car can continue maintaining acceleration for several hundred feet against driver controls. I’ve had to slam on the breaks several times because of this. This is not a glitch, and this is not unique to my Tesla. It’s a known issue reported by the community that needs Tesla’s attention.

My wife and I recently purchased a new 2024 Model 3 Tesla with the autopilot and full self-driving feature. We chose this vehicle because my wife has a long daily commute and we wanted to make the drive easier for her. We test drove a similar model in early August. When we were testing the full self-driving feature, the car failed to safely exit the freeway three times in our short test drive, causing my wife to have to take over. Both times, the car seemed to become confused by traffic cones as it prepared to exit the freeway, causing it to either miss the exit or to change lanes rapidly and unexpectedly, nearly colliding with other vehicles. When we reported this to the employees at the Tesla dealership, we were told that the car needed a software update to address the issue. It is now a month later and we received our vehicle a couple of weeks ago. I have not heard of the release of any software update addressing the issue we experienced. Given that this is the exact feature that prompted us to purchase the car and our intention was to make things safer for my wife, not the other way around, I would very much like to find out when this will be addressed. There are many drivers who currently use the full self-driving feature and I am concerned that it is extremely unsafe.

Twice, could not disengage adaptive cruise control using right scroll wheel. Multiple times, haptic turn signals malfunctioning.

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.

Several times while using traffic aware cruise control, the system will suddenly brake severely for apparently reason. At these times, I was on a lightly traveled interstate with no vehicles ahead of me. Each time, it was during daylight hours and it was sunny. This has also occurred while using autopilot with autosteer and with full self driving. Once, there was a vehicle close behind me, so this sudden braking can be dangerous.

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.

Incident description: one week after purchasing our new Tesla Model 3 2024 , we encountered several error messages upon returning to our car after a brief stop: "app_w264 - lane departure avoidance feature unavailable," "gtw_w075 - steering assist reduced," and "ui_a020 - steering assist reduced. " with no cell signal available, we had to drive back slowly with hazard lights on. The steering was extremely tight, making it very difficult to maneuver. Tesla roadside assistance suggested towing the car and using an uber coupon, which was impractical due to our location in the outskirts of vancouver, canada, with no uber services, and our home in seattle, USA. We drove over 100 miles to the nearest service centre in vancouver, posing a significant safety risk on curvy freeway roads. The service centre confirmed that the wire supplying power to the steering was cut due to contact with the fan, and they repaired the issue. Conclusion: the steering failure of our Tesla Model 3 was a major safety concern. Driving with impaired steering could have led to a severe accident. The issue was due to a design flaw, with the wire contacting the fan. We request a thorough investigation to prevent future occurrences and consideration for the inconvenience and risk we faced. Component/system failure: the wire supplying power to the steering mechanism was severed due to contact with the vehicle's fan. Safety risk: the steering became extremely tight, making large turns nearly impossible and small turns very difficult. This posed a significant safety risk, especially while driving on curvy freeway roads. Inspection & problem confirmation: the problem was confirmed by the Tesla service centre in vancouver. They verified that the wire was cut due to contact with the fan. Errors: "app_w264 - lane departure avoidance feature unavailable" "gtw_w075 - steering assist reduced" "ui_a020 - steering assist reduced".
