2025 TESLA MODEL Y Lane Departure Problems

SUMMARY OF SAFETY DEFECT: Multiple critical safety systems randomly disengage without warning while the vehicle is in operation, creating an immediate crash hazard. DETAILED DESCRIPTION: For approximately one month, my vehicle has experienced intermittent, unpredictable failures of multiple safety-critical systems while driving. These failures occur randomly during operation and include: Regenerative Braking System Failure (PRIMARY SAFETY CONCERN) Lane Departure Warning System Failure Automatic Vehicle Hold System Failure Traction Control System Failure Automatic Emergency Braking System Failure Electronic Stability Control System Failure SAFETY HAZARD ANALYSIS: The sudden disengagement of regenerative braking while driving poses an acute collision risk. Tesla vehicles are designed with regenerative braking as the primary deceleration method when releasing the accelerator. Drivers develop muscle memory and expectations based on consistent vehicle behavior. When regenerative braking unexpectedly disengages mid-drive, the vehicle's deceleration characteristics change dramatically and without warning, creating a dangerous situation where: The driver expects normal deceleration upon releasing the accelerator The vehicle instead continues at speed, requiring sudden brake application Reaction time is insufficient to compensate for the unexpected behavior change Rear-end collisions or other crashes become likely, particularly in traffic Similarly, the Automatic Vehicle Hold feature unexpectedly disengaging means the vehicle may roll when the driver expects it to remain stationary at traffic lights or stop signs. PATTERN AND FREQUENCY: These system failures occur randomly and unpredictably while driving. The issues sometimes resolve after: Restarting the vehicle Restarting the cent However, the failures recur without warning during subsequent driving.

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!

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.

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.

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 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.

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
