Adaptive Cruise Control Problems of Tesla Model Y - part 2

Vehicle was stopped at a red light. On its own it began driving- accelerating forward from a complete stop - ramming the car in front - then into an active intersection. Thankfully the steering was responsive but not the brake until a few seconds after incident began. Miraculously no one was injured. We have Tesla’s dashcam video of incident but unable to upload onto this platform (it only takes photos).

When using fsd, I've noticed that on occasion at a red light, the car will start moving, albeit very slowly, a fraction of a second before the light turns green. I've assumed the car was watching the traffic lights from the other direction using its cameras. So on the [xxx] when this happened, and the car started moving I let it go thinking the light was about to turn green. But I was shocked that the car drove through the red light. Admittedly there were red lights in all directions. I know I'm supposed to be keeping control but it was so shocking that by the time I reacted the car was already in the intersection so I let it go. I downloaded a recording of it. [xxx] information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

After installing software version 2024. 45. 25. 15 (full self driving software 12. 6. 2) on my 2020 Tesla Model Y with autopilot hardware v3, I experienced unsafe behavior by the autopilot/automatic safety system. On my second drive after the software update, I was unable to engage the autopilot system. Two “phantom” cars appeared on the full self driving visualization. One “phantom” vehicle was on the left side of the vehicle in my blind spot. A second “phantom” vehicle was shown about 20 feet ahead and 50 feet to the left of my vehicle. (see screen shots). When I attempted to turn left, the automatic lane keep and blind spot warnings took over and attempted to avoid the phantom vehicle. I was able to override the system, but it caused repeated alarms and attempts to move the vehicle back into the lane.

This complaint addresses the recent changes made to the cruise control system in Tesla vehicles, as per NHTSA guidance in 2024. While the update aims to simplify the activation of enhanced cruise control, it introduces significant disadvantages and safety risks that need to be addressed. 1. Cruise control activation update: NHTSA guidance: in 2024, Tesla was required to modify the activation process for enhanced cruise control, allowing it to be engaged with a single pull when the option is selected. There are two options available: single pull and double pull. Advantages: ? the update simplifies the process, enabling users to activate enhanced cruise control with a single pull, which is more convenient and user-friendly. Disadvantages: ? when the enhanced cruise control is activated and the turn signal is engaged, the system automatically deactivates. ? this deactivation causes the vehicle to stop maintaining its set speed, leading to a slowdown or complete stop. 2. Safety risks: driver reaction: ? the sudden deactivation of cruise control requires drivers to quickly move their feet back to the gas pedal to maintain speed. ? this is particularly concerning when attempting to change lanes or merge into tight spaces, where maintaining speed is crucial for safety. Loss of safety features: ? upon deactivation of the enhanced cruise control, the vehicle no longer maintains a safe following distance, transferring full control back to the driver. ? this abrupt transition means that the driver is left without the system's assistance to ensure safe driving and timely reactions, potentially increasing the risk of collisions. Increased driver workload: ? drivers must frequently reactivate cruise control after changing lanes, which demands additional effort and diverts attention from the road. ? this constant need to manage the cruise control system can lead to driver distraction and increased cognitive load, potentially compromising road safety. 3. Recommendations: see attche.

Tesla full self driving v13. 2. 2 attempted to make a left turn while having a red light. The vehicle successfully came to a complete stop due the red light but once traffic cleared the intersection it attempted to proceed with the left turn while still having a red light. I immediately took over preventing the car from entering further into the intersection.

I was trying to reverse the car from my garage. I turned on the engine and put the vehicle in reverse gear. The vehicle just zoomed out of the driveway leaving me without the ability to control it and hit a tree on a neighbor's house and stopped. Then I tried to bring the car into the garage by engaging the drive gear. Again, the vehicle zoomed into the garage, hit a few objects in the garage and stopped. At that point I just turned off power and walked out. I took pictures of the damaged parts. At that time, I only noticed damage to the rear on the driver side and the front on the driver side. When a tow-truck came a couple of days later, I noticed damage on the front on the passenger side also. When the incident happened , the street was empty and luckily no one (including me) was hurt n.

On drives longer than 40 miles, camera faults cause cruise control systems to degrade in function and then when the faults are cleared, full functionality resumes without driver alerts. Side repeater camera feeds and rear camera feeds inconsistently load, or take an extended time period to load (10+ seconds). Tesla has confirmed that the autopilot computer (hw3) likely needs to be replaced, but this error/messaging is not directly accessible to the customer. The inconsistent failure behavior of the vehicle could easily lead less technical owners/drivers to incorrectly interpret how the car is behaving. The only message you receive while driving could be that 'cruise control is not available', and 'automatic emergency braking unavailable' with a message that the features may be restored later in the drive. My coworker has a 2022 Model Y and the same component failed on his vehicle and needed to be replaced under an extended warranty that was purchased from Tesla. I'm unsure how widespread the failure of this critical safety system is; we both purchased fsd and both had the same component fail and need replaced. I don't personally know others who own this vehicle with the fsd package to know for sure.

I took delivery of the Tesla Model Y yesterday (12/24/2024). The car has 73 miles on it as of now. First, the rear view camera stops working this morning (12/25/2024) and parking assistant is not available. Then the autopilot won't turn on and the car shows an alert that "power limited". After I arrived home from a supercharger (the car is charged to 80% as of now) around 1pm, the screen turns brick, and it will not turn on again after rebooting. It can drive, but the power feels weak. I called Tesla roadside service. The car has been towed to the fresno service center.

The fsd feature for which we have paid in full to Tesla does not work. No cruise control and no assisted steering control or cruise control works. As per their service department, ap4 car computer has internal short and camera can not communicate for above mentioned features.

Cameras stopped working which made all of the safety functions and gps stop working as well.

The car lost all adas functions, and gps on the onboard navigation system. In addition. It can't use regular cruise control and it does not have rear view mirror blind spot warning capability any more. This all happened when the car attempted to install the "holiday" updated from Tesla automatically around 11/29/24 .

While using cruise control (tacc) or fsd, the vehicle inadvertently brakes until vehicle stops, due to detecting light glare or other things as a collision threat. This happened many times. Reported to Tesla service, they said it is a bug and I should file a bug report. I have previously filed many bug reports about this but no software update fixed the problem. Incident happened many times, Tesla should have records of all, because when there is a disengagement, driver is asked to tell what happened by voice.

Accident report [xxx] I was driving on [xxx] fort smith ar to bentonville car was on autopilot, it was raining on and off and with all other cars we were driving around 70-80 mph all the sudden it started a short slip on the right then second after that it started spinning and took us out of the road car totaled car. I believe problem is autopilot did not disengage when car started to slip but instead it was still on until the car got out of the road and hit a large tree. This is 3rd time for me to have this type of accident with same situation slip then spin then out of the road. I believe autopilot is the problem here 100%. This autopilot system is very dangerous. I had enough of this and im hoping national highway traffic system will step in. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

On 12/16/2024 my vehicle received software update 2024. 39. 15, after installing the update I went to the grocery store and noticed nothing was working in the car except basic driving functionality. Cameras were showing up as a black screen. Tacc, aurosteer and fsd supervised were no longer working as well as aeb,fcw,bsm,ldw,lkas and the gps had me in the middle of the ocean, headlights on during broad daylight. I informed a service center by my home and they simply didn’t care, I took it to another service center 50 minutes away and they took two days to do repairs and diagnostics, I was told the computer had shorted out and the technician replaced the car computer and ai4 (hw4) computer system which runs safety features. A software update physically pushed from Tesla should not be shorting out computers on its vehicles, I heavily rely on the cameras and safety features since living in a state where nobody knows how to drive (lol). I hope my vehicle is fixed and this issue doesn’t persist anymore.

Around Dec 16 all cameras in my 2024 Model Y Tesla stopped working and it has not worked since that date. This affects many systems, the most important of which is that I now have no rear backup camera. I believe vehicle manufacturers are required to have functioning back up cameras. I notified Tesla service on 12/16 and was told there was a known computer hardware problem which would cause my incident. Tesla service told me they were unable to obtain the needed computer replacement for a month at least. They informed me there was no safety risk, but I disagree since I don’t have a functioning back up camera, nor lane change camera assistance. Also the display panel is very dark and impossible to read most of the time, posing another safety concern. Why has Tesla not issued a public statement about this problem, and why has NHTSA not mandated a formal recall?.

Vehicle information: • make: Tesla • model: Model Y • year: 2024 description of the problem: after a software update pushed by Tesla, the ap4 computer in my 2024 Tesla Model Y shorted out, causing a complete failure of all systems controlled by this computer. The following safety-critical and driver-assist features have become non-functional: cruise control (adaptive or otherwise) back up camera forward collision warning lane departure warning lane keeping assistance blind spot warning parking collision warning full self-driving and auto park features cameras required for autopilot functionality additionally, because the gps system has failed, the vehicle’s navigation system is inoperable. This impacts Tesla’s unique route planning feature that sets up supercharger stops during long journeys. Without a functioning navigation system, I cannot properly plan my travel or locate charging stations, which severely affects the usability of the vehicle. Safety concerns: the failure of these systems, especially safety features like forward collision warning, lane keeping assistance, and blind spot monitoring, puts both the driver and others on the road at risk. Losing access to safety-critical functions after an update is unacceptable and poses a serious danger to vehicle occupants and surrounding traffic. Incident details: • the issue occurred immediately following a software update. • Tesla pushed the update remotely without providing any warning or indication of potential risks. • the failure appears to be related to a hardware short in the ap4 computer, directly caused or exacerbated by the update. Desired outcome: • a thorough investigation into Tesla’s software update process and its effect on vehicle hardware and safety systems. • a resolution that prevents similar failures in other vehicles and ensures system updates do not compromise vehicle safety or critical functionality.

Navigation is frozen. No cameras work. No full self driving features work. No cruise control.

After a recent software update - all cameras/sensors/cruise control/adas systems are no longer functioning.

Bought my Tesla Model Y on [xxx]. Exactly one month later on [xxx] I start my car to find that none of the cameras are working. This means autopilot, cruise control, rear camera, blind spot monitoring and many more safety features are completely down. In addition the gps does not function meaning my car is not trackable and maps don't work, another safety concern and main reason we bought the car. This is a widespread issue that Tesla service centers have been informed about from Tesla that it is a bad computer that needs to be replaced - in a 1 month old car. My only option is to wait for a computer to be assigned to me which is at earliest on January 21st of 2025, almost 6 weeks without a fully functioning brand new $46,000 car with only 1400 miles on it. Tesla are also unwilling to make any kind of restitution such as a loaner car, or a refund for the full self drive and connectivity packages I just purchased but cannot use as my car is broken. Here is a link to an article showing this - [xxx] information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

All the cameras on the vehicle were unavailable starting today (12/08), including the rear view camera. The vehicle was not drivable and no cruise control was working.

All of the cameras on the vehicle are no longer working after the latest update. This means all sensors (even as simple as windshield wipers) do not work. All driver safety assistance does not work.

According to Tesla the ai4 computer experienced an internal short circuit. This has rendered all cameras including backup camera, gps, parking sensors, and automatic wipers inoperable. The visibility out of the vehicle is very poor to the rear without the backup camera. Parking without the rear camera and parking sensors is difficult. Not having physical controls for the wipers makes turning them on/off and changing speeds difficult, causing a lot of drivers distraction.

After a software update pushed by Tesla, the ap4 computer in my 2024 Tesla Model Y shorted out, causing a complete failure of all systems controlled by this computer. None of cameras on my vehicle are now viewable. Due to the design of the vehicle, reversing without having a backup camera functional is a hazardous event. Also, the following safety-critical and driver-assist features have become non-functional: -cruise control (adaptive or otherwise) -forward collision warning -lane departure warning -lane keeping assistance -blind spot warning -parking collision warning -full self-driving and auto park features -cameras required for autopilot functionality -gps system has failed, the vehicle’s navigation system is inoperable. Safety concerns: the failure of these systems, especially safety features like forward collision warning, lane keeping assistance, and blind spot monitoring, puts both the driver and others on the road at risk. Without a backup camera, the risk of causing injury to people or property is greatly increased. Losing access to safety-critical functions after an update is unacceptable and poses a serious danger to vehicle occupants and surrounding traffic. Incident details: • the issue occurred immediately following a software update. • Tesla pushed the update remotely without providing any warning or indication of potential risks. • the failure appears to be related to a hardware short in the ap4 computer, directly caused or exacerbated by the update. Desired outcome: • a thorough investigation into Tesla’s software update process and its effect on vehicle hardware and safety systems. • a resolution that prevents similar failures in other vehicles and ensures system updates do not compromise vehicle safety or critical functionality.

The automatic pilot computer (ap4) failed on my 2025 Tesla Model Y after approximately 400 miles. This controls a lot of the vehicle's auto pilot features but it also controls a lot of its safety features, such as the back-up camera, forward collision warning and blind spot warning. As of 19 December, the Tesla service center has had my vehicle for 14 days with no fix for the foreseeable future.

They advertise it as a computer failure. The cruise control doesn't work, none of the cameras displays, causing me to hit the lawnmower in my garage. Other functions as navigation, range prediction, and automatic light/dark display switching don't work either.

After latest Tesla software upgrade, all cameras and gps stops working. All automatic functionalities of the car stops working without cameras, and it is really unsafe to drive, for example back up the car since the physical rear view mirror is very small, and car is naturally designed with those cameras to function properly.

The computer is not working which connects to the forward collision warning system, navigation, and all safety when it comes to driving. I am still waiting to hear back from Tesla about the problem and haven't had a resolution.

2024 Tesla Model Y. All cameras and gps used for safety and convenience features suddenly stopped working. Everything was working when vehicle parked for the evening, next morning cameras and gps stopped working. No accident or other incident associated with it. No longer able to use: backup camera automatic cruise control (including full self drive (supervised)) blind spot warning when changing lanes. Navigation parking collision warning automatic braking there is concern with safety of vehicle overall since many of the safety features rely on Tesla cameras.

Safety is the first think that I believe.

Tesla has told me the ap4 computer has failed in my car which has resulted in them having to replace it. I had this issue start right around thanksgiving. I scheduled the soonest appointment available for 12/16 however Tesla contacted me and moved my appointment because they stated that the part was unavailable at this time and should be delivered by 01/20/25. Not offering me a rental or anything on my brand new '24 Tesla. It has just over 1,000 miles on it and is ~3 months old now. 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 to 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.

Tesla shared I have an ap-4 computer short that disables all cameras (rear back up camera, blind spot camera, lane deviation detection, emergency assisted forward braking), navigation, and auto lighting features are disabled. Other non-essential features do not work as well.

We were driving east on I-40 at mile marker 245 Friday Nov 29 2024 around 8:50am in the right lane. We were passed by a gray Ford f-150 on the left. We had the "traffic aware cruise control" enabled. Our Tesla braked hard when the f-150 was directly beside us. The Ford was not in our lane at any point, and never changed lanes. Luckily a car behind us was not following too closely or an accident could have happened.
