Adaptive Cruise Control problems of the 2025 Tesla Model Y

The vehicle was in supervised full self driving on the turnpike, when all of a sudden it darted out of the lane into th grass hitting a guard rail.

Incident report – Tesla y – unintentional acceleration Saturday November 29, 2025, approximately 2:40 pm on the above-referenced date and time, we were returning home with the intention of pulling the car into our garage, an activity performed over a hundred times in the one year we have owned the car. Because of the need to back in to allow the car to be charged, the following procedure is adhered 1. Disengage self-driving (if it was being used) in the street prior to entering the courtyard for residence. 2. Pull forward three-quarters of the way into garage (since the residence is the last on the courtyard and the car cannot be pulled beyond the garage opening to directly back in). 3. Place car in reverse and slowly perform k-turn to back into garage. On the date in question. The following anomalies occurred: 1. After placing the car in reverse (action 2), instead of starting to back out, the car lurched forward. The brake was immediately applied and the car stopped about a foot before hitting the garage wall. 2. The brake was applied again to assure self-driving was disengaged and proceed with action 3. 3. Car was placed in reverse and accelerator was lightly pressed to slowly back out of garage. Rather than slowly back out (as was done hundreds of times) the car immediately accelerated and rapidly gained speed. 4. The brake was applied to stop the car but could not overcome the acceleration (pictures of skid marks were taken). 5. In order not to directly hit the wall located across from garage, car steering wheel was turned to minimize any direct contact ( skid marks will show turn). 6. Car came to a stop when it hit the wall causing significant damage to the car and causing damage to the wall (pictures can be forwarded).

While on a two lane road, my car decided to go around the car in front of me into on-coming traffic while in full self-driving mode. I had to jerk the car to the right to prevent a head-on collision!!!! I missed the on-coming vehicle by seconds!!! this was terrifying!.

In fsd mode, my Tesla Model Y always heads to the "do not enter" road and I have to take over manually to prevent entering the "do not enter" road. This has happened almost all the time I am there. This is a very unsafe. Tesla needs to correct this issue at their highest priority.

I have had multiple incidents of "curvature assist active" message appearing on screen while on cruise control. It suddenly reduces the speed of the car. This happens on a straight road with no curves or slope. It also happens at random. On the same stretch of road at the same time of the day, this issue pops up sometimes and doesn't on other times. Every time this comes up, the car reduces speed suddenly. For example, I go from 45 mph to 23 mph in a few moments. If there is a lot of traffic behind me and the car behind me was not expecting such a sudden decrease in speed as there is no obstruction in front of me, this could lead to a safety issue. I took the car in for repair. The technicians could not find out what the issue was. They said they recalibrated the sensors and test drove and did not see this occur. As this is occurring randomly it might not have shown up when they test drove. But, it happened to me when I took the car back and it keeps happening randomly at least twice a day. There is no specific location and/or time of the day. Tesla doesn't provide an option to disable this "curvature assist" feature for something so basic as cruise control. Along with this I have had 2 incidents where my car applied brakes suddenly when there was no obstruction in front of me. In both incidents, I had to immediately take over and speed up to avoid any issue with traffic behind me. If there is any safety incident due to these issues, Tesla will have to be held liable.

It is impossible to disable automatic emergency, breaking system permanently. The vehicle brakes strongly and abruptly causing the cars behind to slam on their brakes and potentially cause accidents. Every time I disable it, it comes back on next time we get into the car. There has been several instances where the vehicle hit the brakes really hard, even if there was nothing in front of it. . I was told that this is happening because Tesla does not use sensors but realize on cameras for these features and it can be quite wrong. I don’t know how to drive this car safely because the car makes decisions for me. Since it happens all the time, I’m having to keep my foot on the gas, and when it slams on the brakes, I counter it by pressing the gas pedal. The incident date is just an estimate, but it happens all the time.

While driving westbound on lee jackson memorial highway (u. S. Route 50) after passing the intersection with stonecroft boulevard in chantilly, virginia, the autopilot system on my Tesla Model Y malfunctioned. Without any warning or obstacle in my lane, the vehicle suddenly and sharply veered to the right, directly toward two vehicles traveling in the adjacent lane. I was holding the steering wheel at the time and was able to immediately countersteer to prevent a collision. There were no audible or visual warnings from the vehicle before or during the incident. The autopilot system did not display any messages or alerts, and no braking or turn signal was engaged by the system. The lane shift was abrupt and uncommanded. The dashcam footage clearly captured the incident, and it is available for inspection upon request. To my knowledge, the issue has not yet been reproduced or inspected by the manufacturer or service center. The vehicle has not been examined by police, insurance representatives, or others at this time. This unexpected maneuver created a serious safety risk for myself and nearby drivers.

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.

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 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.

Safety is the first think that I believe.

On or around December 1 2024, the * computer** in my 2025 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 *-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 * 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 * 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.

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.

2025 Tesla Model Y cameras and sensors all stopped working within 700 miles driven from brand new. Affected systems included all cameras, including backup camera, as well as gps navigation, with the gps system believing the vehicle to be static at a Tesla facility in California. This not only prevented the self-driving and navigation from functioning, it caused numerous safety features to be disabled including (mandatory) backup cameras, collision-avoidance system, lane-departure warning system, cross-traffic alert system, rear collision avoidance system, and automatic safety braking. Upon reporting to Tesla, was told a "new component" was required, which later was told was a new computer. The manufacturer initially set a date 2 weeks in the future for a repair; then they pushed it a month; then tried to push it another month before I pushed back. This resulted in it being taken in earlier than the repair date. The vehicle is still awaiting repair. There were no warnings of this failure, it simply all happened at once. Upon confronting Tesla service with this being a known issue [xxx] ) and requesting a loaner for the meantime, they eventually found one, but only after great protestation and pushback, with eventual threats of legal action leading to a more personal touch. This is clearly a known issue which they are downplaying. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).
