2025 Tesla Model Y Driver Assist & ADAS Problems

Car was in FSD mode, backing out of a parking place very slowly when it accelerated and crashed into a post and wall. No other cars or people were involved, but no alarms, beeps, or warnings were sounded and the screen/monitor/camera systems went blank simultaneously. This caused over 5000 worth of damage per the estimate provided by the only body shop in the area allowed to fix Teslas. There is also a gap in saved data per our retrieval from the USB and camera installed in the vehicle.

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 to: 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).

Self driving was maintaining vehicle. Looked at roadway before reaching down to passengers side for water bottle. The weight shift in the seat turned the self driving off immediately while turning sharp left. The Tesla Model Y crossed the left interstate lane barely missing an 18-wheeler. Drove 80mph in the central ditch, branches, and rocks. Car was still in drive, and rolled up to roadside which was covered in dust. The two eighteen-wheelers that I cut off then Drove away, and drove tesla to next exit to see damage.(dashcam footage available.)

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!

Vehicle Autopilot settings with default settings, 1) traveling marked highway speed of 75 mph, vehicle detects something in either the lane to the right or left will slam on the brakes possibly causing a rear end collision, 2) traveling at marked highway speed of 75 mph, vehicle detects curve signs either to the right or left will slam on the brakes possibly causing a rear end collision, 3) traveling in town at marked speed of 40 mph, vehicle detects a vehicle turning at a safe distance for the speed either right or left will slam on the brakes possibly causing a rear end collision. Vehicle Autopilot settings: Forward Collision Warning “OFF”, Lane Departure Avoidance “OFF”. Emergency Lane Departure Avoidance “OFF”, Automatic Emergency Braking “OFF”, Obstacle-Aware Acceleration “OFF”, will remain set for the current drive without any of the above safety issues. Next drive the Automatic Emergency Braking “ON” and the above safety issues can happen. Tesla must make immediate software improvements in the Automatic Emergency Braking system and/or allow continual “OFF” setting disabling of the Automatic Emergency Braking system.

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.

Shortly after purchasing the vehicle in late 2024, I began experiencing multiple safety-related malfunctions. These issues include: Full Self-Driving (FSD) malfunction: On the third use of FSD, the vehicle attempted to enter a left-turn lane but failed to fully move into the lane, resulting in the right front panel of the vehicle colliding with the bumper of a truck in the adjacent lane. There were no warnings from the system prior to the collision. The incident occurred at low speed. The truck sustained no visible damage, and the rubber from the truck's bumper transferred to the car, which was removed by hand later. This event raised serious concerns about the safety and reliability of the FSD system. No police report was filed, and the manufacturer was not present at the scene. Backup alert system failure: On several occasions while reversing, the car failed to issue audible or visual alerts despite vehicles being within 10–15 feet. In one instance, the screen finally showed a red zone when a car was within 10 feet, but still provided no audible warning. This issue has been intermittently reproducible but not consistent. It poses a significant risk to pedestrians and other drivers, particularly in low-visibility or driveway situations. Manufacturer's Response: The vehicle was inspected by Tesla. After one in-person service visit and extended discussions, Tesla service representatives stated there was “nothing more they could do” and that a buyback was the only next step. A buyback request was submitted by a Tesla representative but has not been acknowledged or resolved more than 45 days later.

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.

on 2/15/2025, while backing out of a driveway at about 7:30PM, the vehicle backed into a parked car directly behind it parked in street. There was no warning signal emitted that an object was behind the car. There was no safety alert on the display. Essentially the vehicle's sensors did not see the vehicle directly behind it.

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.

All cameras and related functions stopped working, including back up camera. GPS is not working. Tesla pushed back my service appointment until 1/21/25. Safety is an issue now due to blindspots and they will not give me a loaner car. Tesla informed me the computer needs to be replaced. They reported this is wide spread and Tesla is not sure why it happened. I was informed that even though my new appointment is 1/21 it is likely that it would be pushed back further. I have only had this car for 5 weeks. No warning lights came on prior to this happening.

Here is my draft: Vehicle Information: • Make: Tesla • Model: Model Y • Year: 2025 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. 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. Quality control for Tesla software updat

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.

Computer system failure causing all cameras to fail, mirrors to stay darkened even in daylight, navigation system not updating, collision and lane departure feature failure. Issues were reported to Tesla and an AP 4 computer replacement were scheduled, however service has been delayed for several weeks ( now 9 Jan 2025). The car does not feel sufficiently safe to drive with the impaired mirror visibility couples with the lack of any cameras or safety features working.

The camera and GPS failed with 3 weeks of taking possession of this new lease. After several days in the shop, TESLA informed me THE MAIN computer was broken and needed to be replaced, but it was back ordered. They asked me to reopen their loaner and drive this defective car, until the computer comes in.

The Automatic Pilot Computer (AP4) failed. This controls a lot of Tesla Model Y'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. Another safety concerns is the GPS navigation is no longer function because of the AP4 failure. Navigation is critical in the Tesla ecosystem in order to navigate the charging infrastructure to maintain a charge during road trips. Tesla has admitted to the issue but has done nothing to fix it. I have attached screen shots of the conversation with their service technicians. There is also a picture of the AP4 short remove and replace task for service.

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.
