2025 TESLA MODEL Y Electrical System Problems

My vehicle experienced multiple safety system malfunctions before a minor collision occurred. While driving, the car displayed warnings indicating that traction control had been disabled, followed immediately by a warning that the automatic vehicle hold/brake hold was disabled. These failures happened before any impact. At the same time, the vehicle’s cameras were not functioning correctly, and the vehicle did not provide any forward collision warning. The automatic emergency braking system also did not activate. Because these systems failed, the vehicle did not warn, slow down, or brake to avoid a collision. After the collision, the vehicle showed several additional safety system failures. These included automatic emergency braking unavailable, and repeated safety restraint system faults affecting both the front left and front right restraint systems. The airbags did not deploy even though conditions suggested they should have, and afterwards the vehicle displayed persistent airbag and seatbelt system error icons. The restraint system appears to have gone offline. The vehicle is currently unsafe to drive due to failures in braking, traction control, perception/camera systems, forward collision warning, automatic emergency braking, and the airbag/restraint systems. These failures occurred before the collision, contributed to the collision, and continued afterward. The manufacturer’s service center has declined to provide towing or a loaner or rental vehicle while the safety defects are being investigated, which will take about 30 days.

The horn becomes MUTED during rain. Major safety defect. Tesla service center checked and replied 'it works normal when water driesd out'. This is a major safety problem. Technician is telling me that's how it is, does that mean raining days I have to drive without a functional horn? Sunny days it works fine, as that's how every vehicle should be. But under slippery, foggy and limited vision raining days, car becomes mute on horn, how would that be fine and normal? The horn is a federally mandated safety feature. A horn that fails in the rain is a safety defect. Tesla need to have attention on this and either fix the issue or replace the horn with other better designed product. I'm not the only model y owner who has this issue, Google it, you'll see that's a 'common problem '

I am filing this complaint regarding recurring safety, security, and system failures in my Tesla Model Y, concerns about unauthorized access, and Tesla’s refusal to provide complete diagnostic and privacy data. These issues have directly endangered my safety and prevent me from confirming whether the vehicle has been compromised. The vehicle’s touchscreen and associated software systems repeatedly failed. An unfamiliar key fob activity was detected on July 27, 2025 and on at least two occasions prior to July 27, 2025, the touchscreen went black and could only be restored via a full hard reboot. Safety Risks: * Loss of touchscreen functionality could disable access to critical driving and emergency controls. * Potential unauthorized access poses risks of theft or malicious interference with the vehicle. * Chemical/gas odors could indicate exposure to harmful substances. Tesla service center inspected the vehicle but reported no issues; I believe the inspection may not have been fully conducted as requested. The vehicle has not been independently inspected outside of Tesla. Police and insurance representatives have not been involved. Warning Signs Prior to Failure: * The touchscreen went black twice in the two days prior to July 27, 2025. * Unfamiliar key fob activity was detected on July 27, 2025. * The charger port opened by itself multiple times. * The vehicle locked while I was inside on one occasion. Attempts to Resolve: * Tesla’s mobile service rescheduling and service center inspection did not identify or resolve the issues. * Five privacy/data requests submitted to Tesla for access and diagnostic logs returned incomplete, empty, or irrelevant files. Desired Outcome: * A complete copy of all records and data related to my vehicle, including access logs, diagnostic logs, security/camera events, and system communications. * A thorough, transparent inspection of the vehicle by Tesla, conducted in my presence, with full documentation of findings provided.

Smoke began coming out of the vents while driving. Battery was at 2%. Driver pulled over, exited vehicle and within 2 minutes flames could be seen (on video) coming from the center, dash area of the vehicle. Fire developed rapidly. Lt.

During the autopilot self driving feature the model Y was stopped at a red light waiting to make a left turn. For an unknown reason it proceeded through the red light. Cross traffic had to aggressively break to avoid an incident. Not sure what causes this glitch.

I bought a tesla model Y 2025 and got my car delivered on [XXX] I barely drove it and within a week, I noticed all sensors stopped working (ALL cameras and camera-related functions stopped working, including the legally mandatory backup camera for new cars, GPS has stopped working, making the premium connectivity package I paid not usable). Not only was I not able to use the self driving capability, which I paid $8000 for, but also the car lacked the most basic safety features. I contacted Tesla service center, they refused to admit that the sensor malfunction is a security concern, and still put me on an appointment three weeks later (dec 13). After the first appointment, they did not fix the problem at all and noted it was a major computer issue, as reported by several media outlets [XXX] ). So my brand new car has a defective core component upon delivery. I was scheduled to meet them after they get the computer part on Dec 27. The appointment was rescheduled to Jan 14 again for missing parts. During the process, I found some weird tricks online and semi-fixed my car’s navigation but the sensor issues still exist. And on Jan 14 again, they claimed the computer part was missing again and I had to wait until that upcoming weekend to fix it. To summarize the situation: I was given a car that is defective upon delivery on its most important core component for 2.5 months, when the car lacks even the basic legally required safety features, as well as premium features that I already paid off! During the process, I also spent a lot of time dealing with their customer service, and rescheduled appointments (I even had to drive to their service center several times to get a loaner and had to return the loaner early before they did not have parts to fix my car). Their negligence on safety, and promised features is simply astonishing and unacceptable. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The contact was an attorney calling on behalf of the owner of a 2025 Tesla Model Y. The contact stated that the owner was driving on a neighborhood street at an unknown speed with Autopilot engaged when vehicle control was lost. As a result, the vehicle crashed into a traffic light pole where it came to a stop and caught on fire. The owner was unable to exit the vehicle and was pronounced deceased on the scene. The origin of the fire was the lithium battery. The location of the fire was under the front end of the engine compartment where the battery was stored. The fire was extinguished by the fire department. A police report was filed. The vehicle was towed currently in the possession of the Police Department pending the cause of the crash. The vehicle was destroyed. The light pole was damaged. It was unknown if the air bags were deployed. The manufacturer was not notified of the failure. The failure mileage was unknown.

Automatic Emergency braking stopped working. Parking assist stopped working. Back window is dismal. You can't see anything behind through the window. All cameras stopped working and it poses a safety hazard.

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 December 7, 2024. I scheduled the soonest appointment available for December 24, 2024 however Tesla contacted me and moved my appointment because they stated that the part was unavailable at this time and should be delivered by January 24, 2025. Not offering me a rental or anything on my brand new 2025 Tesla. It has just under 1,000 miles on it and have the car since November 8, 2024. 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. This has increased the safety risk of my vehicle tremendously. Tesla has not seemed to publicly acknowledge the issue yet either.

On or around December 1 2024, the **AP4 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 **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.

Safety is the first think that I believe
