2025 TESLA MODEL Y Complaints

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.

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.
