2024 Tesla Model Y Speed Control & Cruise Problems

The car spontaneously accelerated while approaching a stop sign. I was able to hit the brake to stop it.

Recently Tesla released it's latest version of FSD, v14.1.4. One of the key features is the revamping of the driving modes: sloth, chill, standard, and mad max. Tesla also removed the ability to manually increase or decrease the speed of the car. This is a problem. Let me illustrate it with a real-life example. Yesterday I was driving of a 40 mph road and the car correctly set the speed. I was using the standard mode so the car allowed an overage of around 10% so the actual speed was 45 mph. In our area this is typical for most drivers. As we entered a village, the posted speed limit was changed to 30 mph. The panel was perfectly visible and readable. The car did not register it and continued at 45 mph. I changed to mode to "sloth" and the car decreased its speed to 40 mph but I was still 10 mph above the legal speed limit. I came across a second 30 mph panel and again the car "ignored" it. Because I did not have the ability to manually reduce the speed of the car, I had to disengage FSD and drive the car by myself. Tesla claims FSD must be supervised. Fine. But removing the ability to manually change the speed of the car should be a requirement not a design preference.

Tesla removed the speed limit offset feature in FSD version 14.1.4 and now only uses speed profiles called Sloth, Chill, Standard, Hurry, and Mad Max, and this has made my car extremely unsafe to drive. The problem is that these profiles make the car go either way too slow or way too fast and I cannot adjust it to match actual traffic conditions anymore. To make matters worse, the speed limit detection is broken and frequently shows the wrong speed limit for the road I am on. When I use Sloth, the car never goes over the detected speed limit no matter what, so if the system thinks I am in a 35 mph zone when I am actually on a 55 mph highway, my car crawls along at 35 while traffic is flying past at 60-70 mph. I have people tailgating me, honking, flashing their lights, swerving around me dangerously, and I have almost been rear-ended multiple times because my car is going so much slower than everyone else. Without the ability to set a maximum speed offset, I am stuck going whatever speed the broken detection system thinks is right. If I switch to Standard, Hurry or Mad Max to try to keep up with traffic, sometimes the car goes way too fast for the actual conditions or blows through school zones and residential areas at unsafe speeds. I cannot fine-tune the speed anymore to drive safely with the flow of traffic. I am forced to either be a rolling roadblock and risk getting hit from behind, or use an aggressive profile that might go dangerously fast. This happens every single time I use FSD now and the combination of broken speed limit detection plus no manual offset control has created a seriously unsafe situation. I feel endangered every time I drive and I am genuinely worried about causing or being in an accident.

After a recent software update - all Cameras/Sensors/Cruise Control/ADAS systems are no longer functioning.

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: 1.Cruise Control (adaptive or otherwise) 2.Forward Collision Warning 3.Lane Departure Warning 4.Lane Keeping Assistance 5.Blind Spot Warning 6.Parking Collision Warning 7.Full Self-Driving and Auto Park features 8.Cameras required for Autopilot functionality Additionally, because the GPS system has failed, the vehicle’s Navigation system is inoperable. The GPS stays in the last position prior to the update. 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.

Starting on 12/4/2024, my car's camera stopped working, no blind spot warning, no navigation, no rear view camera and no cruise control. Reported to Tesla on 12/8 and they said it is a known problem nationwide and some Autopilot computers are getting shut or something. They have given me an appointment for 1/4/2025. The vehicle is really unsafe to drive without these components working and the vehicle draws on heavy amount of battery usage without these controls and for my commute on highway, I am always nervous about if there is going to be enough for me to reach the next charging station. I would expect this falls into safety recall and Tesla should at least send out a service bulletin as well as provide alternate vehicles for the owners to use until this can be fixed.

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 01/03. Not offering me a rental or anything on my brand new '24 Tesla. It has just over 1,000 miles on it and is ~1 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, back camera, 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.

#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.S.C. 552(B)(6)

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.

The contact owns a 2024 Tesla Model Y. The contact stated that while driving approximately 15 MPH the vehicle suddenly experienced unintended acceleration causing the driver to lose control of the steering and crash into a second vehicle. During the crash, the frontend of the vehicle was severely damaged but the air bag did not deploy. The contact sustained a right-hand injury that did not require medical treatment. Three occupants from the second vehicle sustained undisclosed injuries and were transported to the hospital. A police report was taken at the scene and the vehicle was towed away. The cause of the failure was not yet determined. The manufacturer and local dealer were notified of the failure. The failure mileage was 7,608.

I was parking the Tesla Model Y at very low speed, when there was a sudden unintended acceleration. The car banged against the wall of a building and was severely damaged. My family - wife and two children were in the car.

The vehicle was under full self-driving mode and approaching a shopping center. There was a crossroad with signs on the corner. The vehicle was supposed to turn left but kept slowly approaching the signs on the corner. I was ready to step on the brake to stop the full self-driving mode while expecting the vehicle to turn left or step on the brake. Instead, the vehicle accelerated toward the signs, so I had to steer the wheel to the left and apply the brake immediately. The vehicle jumped a bit as it ran over the corner of the crossroad and stopped after about 10 feet. I was fortunate because I took action immediately, avoiding hitting other people or property. However, human reactions seem not to be quick enough to prevent some accidents as in this case. During this incident, the right corner of the front bumper of the vehicle hit the signs, and the top right corner of the vehicle (right above the front window) was also slightly damaged.

The contact owns a 2024 Tesla Model Y. The contact stated that while his wife was driving at slow speeds in the driveway, the vehicle independently accelerated. The driver lost control of the vehicle and came to a complete stop after crashing into the garage door. The air bags did not deploy. No warning lights were illuminated. A police report was not filed. There was no injury reported. A dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was 100.

I was on [XXX] heading towards Chicago and following the traffic. I started changing the line to pass the vehicle in front of me and suddenly my tesla completely lost control and started drifting to the sides. I released the accelerator right away but it made it even worse. It seems that acceleration continues to happen that’s what made car to drift. Eventually car slowed down and I was able to make it to my line. I don’t understand why line assistance didn’t work to keep the vehicle stable, why after releasing accelerator the vehicle continued to gain the speed. It was sunny day and dry road. No foreign objects on the highway. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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 or Beta self-driving - when a Minimum Speed Limit sign is detected on [XXX] 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.
