Adaptive Cruise Control problems of the 2024 Tesla Model Y - part 2

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.

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.

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.

On Nov 23, 2023, I was reversing car from my driveway in the morning. Car started giving warnings with issue on all its cameras. While reversing car, it will give error that rear view camera not available. While giving left/ right turn signal, it is showing blank screen for that view. All other safety features like blind spot detection, lane assist are not working at all. I also started getting error message that emergency brake is not available. I have been contacting them for immediate repair/ provide loaner car from same date (11/23/2023). Earliest appointment date given is Dec 11, 2023. This is not acceptable at all. It is very dangerous to drive the car without those safety futures. I am also concerned on any other issues which it has not reported. I don't feel safe to drive the car.

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, specifically [xxx]. I scheduled the soonest appointment available for 12/13 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 2500 miles on it and is ~2 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 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. Additionally, the vehicle came to a stop on the highway when my wife and I were in the car on the night of [xxx], forcing us to perform an emergency pullover and abandon the car 22 miles north of rochester, mn overnight. This has increased the safety risk of my vehicle tremendously. . . Tesla has not seemed to publicly acknowledge the issue yet either.

One day the cameras, gps, and sensors just stopped working and haven’t worked since. Been 4 weeks.

All safety features and cameras on this vehicle are currently disabled. Specifically, the following functions are not operational: forward and parking collision warnings, blind spot warning, lane departure and lane-keeping warnings, rear cross-traffic warning, self-driving capability, adaptive cruise control, navigation system, location tracking, sentry mode, premium connectivity features, reverse camera, front and side cameras. Additionally: the headlights remain on continuously during daylight hours. The interior control panel screen and the side and rear mirror displays are stuck in night mode.

#issue description I experienced an issue with Tesla’s full self-driving (fsd) system when a trailer hitch was attached to my vehicle. From what I observed, the fsd system appeared to detect the trailer hitch as an object in close proximity to the vehicle. This caused the vehicle to accelerate rapidly to the fsd maximum speed of 85 mph, regardless of the road conditions or posted speed limits. This issue occurred when the lane markings were visible, but the hitch obstructed the rear camera’s view. On the fsd display, this obstruction was represented as a persistent “cloud” following the vehicle. I attempted to adjust the maximum speed limit manually to mitigate the acceleration, but this did not prevent the behavior. Each time I engaged fsd, the car would accelerate rapidly, even in situations where such high speeds were not appropriate for the road conditions. # steps taken to resolve the issue I covered the rear camera, which allowed fsd to function normally and prevented the rapid acceleration. The “cloud” visualization on the fsd display also disappeared once the camera was covered. # trailer mode Tesla offers a “trailer mode,” but I did not enable it since I was only using a hitch without towing a trailer. My understanding is that fsd does not operate in trailer mode. # reference: this issue has been reported by other Tesla owners, as discussed here: [xxx] information redacted pursuant to the freedom of information act (foia), 5 u.

I have had multiple incidents of “phantom braking” when using traffic aware cruise control and auto steer. It usually happens on one lane state highways with opposite direction traffic, sometimes with turns or hills. The vehicle has slammed on the brakes without warning, sometimes the warning tone also sounds. Each time there was absolutely no danger, nothing abnormal. On a couple occasions there was traffic behind me, and it must have scared them. They probably thought it was a hard brake check. If I wasn’t able to quickly over ride the braking with the accelerator it very easily could have caused an accident. On two occasions my pregnant wife was in the car and it scared her very much. I am personally afraid to use it now, knowing it’s going to slam on the brakes is nerve wracking and unsafe. Tesla does not seem to care about addressing the issue, rather putting all eggs in the “full self driving” basket instead of improving this very obvious safety defect. From reading online forums it seems to affect just about everyone. I’m hoping their engineers address it and they release a software update correcting it, but as mentioned above it doesn’t seem to be on their list of priorities; the problem has been happening for several years now and has resulted in at least one known fatality. Hopefully the NHTSA can light a fire under them and have this scary safety defect addressed.

While using adaptive cruise control the vehicle regularly decelerates for no reason and without warning "phantom braking". I experience this about once a week, but experienced it multiple times on a longer drive this weekend. The unexplained abrupt braking could result in being rear-ended by another vehicle.

On multiple ocassions when using adaptive cruise control the vehicles slams on the brakes without warning and for no reason and brings car to a near standstill in the middle of traffic unless I slam the accelerator down and fight the car. Engineers from Tesla inspected the vehicle and said everything was working normally, but it continues to malfunction and almost causes accidents with cars behind in traffic having to slam on their brakes as well.

I am reporting a safety defect in Tesla’s full self-driving (supervised) system. On xxx, while using fsd, my 2024 Tesla Model Y (VIN: [xxx]) failed to recognize that the road terminated into the desert after a roundabout on the [xxx] road near [xxx]. The vehicle accelerated straight instead of making the sharp 90-degree left turn, left the roadway, traveled down an embankment, and crashed. Airbags deployed and the vehicle was declared a total loss. Vehicle data recorder (vdr) data confirms that autosteer was active and available during the critical braking sequence. I applied very strong sustained braking (brake master cylinder pressure exceeded 129 bar with abs activation). The tow truck driver, [xxx], stated at the scene that this was the fifth Tesla he had recovered from this exact same location due to similar crashes. This documented cluster of at least five identical Tesla crashes at one hazardous spot indicates that Tesla had actual notice of a dangerous defect in its fsd mapping and road geometry recognition but failed to correct it. This incident aligns with NHTSA’s ongoing investigations into fsd performance issues (including ea26002). I am also pursuing a private product liability claim for damages. I can provide supporting documents including vdr screenshots, the wickenburg fire department report, and a witness statement.

1st incidence: the car with full self driving mode self-changed to shoulder lane on fwy 10 west bound for unknown reason. I had to steer back to my lane to avoid hitting the fwy divider. 2nd incidence: with autosteer/cruise control mode, the car self changed to left lane, again I quickly guided the steering wheel back to my lane to correct the action and it caused a car accident.

My family and I were on i680 heading toward sacramento when the Tesla y suddenly braked. We were using autopilot and going around 70 mph. The car was trying to pull a full stop in the middle of the freeway! I quickly disengaged the autopilot and stepped on the pedal to speed back up. I'm guessing the Tesla saw a hazard on the road and put on the brakes. The problem is there were no hazards. Our safety was put at risk because we could've been reared, and it could've caused a pileup. Luckily, it was early Sunday, and there weren't a lot of cars on the road. We stopped using the autopilot immediately, so the problem has not been reproduced. We have an appointment with Tesla in four days. I will be reporting the incident to them. I'll ask for an inspection then. There were no warning lamps or other symptoms prior to the sudden braking. It was a very jarring experience. I have my kids in the back seats.

I was driving down the highway with my wife and baby at about 65 mph. I was using regular cruise control with no one in front of me when all of a sudden, the car braked extremely hard. Luckily, the car behind me was far enough back to switch lanes and pass me. If it was closer, this could have resulted in a highway accident. The car stopped braking maybe around 30 or 40 mph. I may have it recorded in the Tesla camera system since I pressed the save button approx 4 min after it happened. I also scheduled a service call with Tesla that will hopefully happen on may 7th.

My wife and I purchased a Model Y 2024 just a few weeks ago. We have had multiple experiences when using cruise control where the car inexplicably slows down rapidly when there are no vehicles in front of us decelerating.

While using autopilot with beta self driving installed and stopped at a traffic light, left or right turn traffic signal turning green causes car to move into oncoming traffic (moves straight through intersection).

While driving to work, using fsd, the autopilot steered me into the path of an overtaking vehicle moving at about 20 mph faster than my vehicle. By quickly taking over steering and speed control, I was able to avoid a collision. A couple miles further down the road, the car could not decide on which exit lane to use, and weaved between two possibilities, probably alarming and angering drivers behind me. Again, I had to take over control. Taking over speed and steering control was necessary two more times in my 25 minute trip, most of it on well-marked multi-lane highways. Of the four incidents, only one would have resulted in a serious high speed collision, had I not taken over very quickly. Having coached robotics competitions, and piloted aircraft with autopilot, it is my opinion that the fsd (supervised) software is at alpha stage in development (not yet up to beta stage, at which it could be safely released only to select skilled drivers, with suitable disclaimers and warnings) . At delivery, no introduction to the car's controls is provided, so customers are on their own regarding finding out, by trial and error and the occasional potentially lethal collision, how to safely drive the vehicle with fsd engaged. The manufacturer should be required to instruct all customers on the very high level of vigilance required to operate with fsd engaged.

While using autopilot or beta self-driving - when a minimum speed limit sign is detected on I-75 in georgia, the system usually reduces to the speed of the vehicle to posted minimum speed (40 miles an hour) instead of maintaining current speed limit.

We purchased a 2024 Tesla Model Y approximately one month ago. We have experienced multiple occurrences (10-15) when traffic adaptive cruise control was engaged. Our car suddenly braked for no apparent reason. Last night, while traveling at 65 mph, on a four lane major highway, it happened again, nearly causing a rear end collision. We are hesitant to use cruise control because this feature (t. A. C. C. ) is built into cruise, no way to separate it. After researching online, we discovered this is not a new or unusual event and has been reported by hundreds if not thousands of Tesla owners, dating back at least 3-4 years (if not longer). There are no warnings prior to the event. The car suddenly slams on brakes in what seems to be a “panic stop. ” we understand a record of these occurrences are recorded and available from Tesla at your request. We have registered a complaint with Tesla as well.

Car decelerated drastically to a low speed when driving on the highway using cruise control.

When adaptive cruise control is on random phantom braking occurs. It can be very severe and drops speeds of 20-30 miles within seconds. Occurs on highways and is random and occurs daily. ( multiple times in a day) has been serviced 4 times and Tesla cleans the cameras and adjusts them. It has progressively gotten worse and Tesla said don't bring it in because they cannot fix it. They describe it as a software update.
