2024 Tesla Model Y: windshield wiper failure

Filed May 24, 2026 · Visibility · MI

I am reporting a safety‑critical issue with the automatic windshield wiper system on my 2024 Tesla Model Y. The vehicle uses a camera‑based “Auto Wiper” system, and it consistently fails to activate fast enough during heavy rain, spray from passing trucks, or sudden visibility loss. During moderate to heavy rain, the Auto wipers often stay on a slow or intermittent setting even when the windshield becomes fully covered with water. The system does not increase wiping speed quickly enough to maintain visibility. This results in several seconds where I cannot clearly see the road ahead. This problem is made worse because the Model Y makes it difficult to quickly switch to manual wiper control while driving on the freeway. The driver must look down at the touchscreen and navigate menus to adjust wiper speed, which is unsafe at highway speeds. The delay between losing visibility and being able to manually increase the wiper speed creates a dangerous situation. This behavior has occurred multiple times at highway speeds. When passing large trucks or encountering sudden water spray, the wipers do not react, and the windshield becomes momentarily opaque. This creates a serious risk of losing lane position or failing to see vehicles in front of me. This is a safety hazard because: 1.The Auto wipers do not clear the windshield when visibility is urgently needed. 2.Manual override requires taking eyes off the road to use the touchscreen. 3.The delay in response can lead to loss of visibility for several seconds. I am requesting that the federal safety agency investigate this issue, as it affects visibility and could lead to collisions, especially at highway speeds or during sudden heavy rain.

The automatic rain-sensing wipers on my 2024 Tesla Model Y fail to activate during rain from delivery date, leaving the windshield uncleared and forcing manual activation. To be clear, this feature does not work at. This happens consistently and creates a significant safety hazard due to impaired visibility while driving. Tesla uses a camera-based system rather than a dedicated rain sensor, and despite service visits and software updates, the issue persists. I believe this presents an undue safety risk that should be investigated.

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 on 1/12, and I scheduled the earliest appointment available for 1/30. They did not offer me a rental or any assistance during this time, and I need my vehicle to commute to work and conduct other essential activities. It has just over 1,000 miles on it and is ~3 months old now. This issue impacts: backup camera, 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, and i have received no reparations for it.

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 [XXX]. I scheduled the soonest appointment available for 12/30 however Tesla contacted me and moved my appointment because they stated that the part was unavailable at this time and should be delivered by 01/9/25 but now it has been pushed back to 1/20/25. Not offering me a rental or anything on my brand new '24 Tesla. It has just over 1,000 miles on it and is ~3 months old now.

The computer suddenly failed on [XXX] due to a short circuit caused by a manufacturing defect in certain 2024-25 Model Y vehicles. This causes nearly all advanced functionality and safety features of the car to fail completely, including all cameras, parking assist, full self-driving, autopilot, autosteer, autopark, cruise control, lane keep, lane departure warning, blind spot monitoring, auto windshield wipers, map, GPS navigation and more. Also, the car does not sleep, resulting in excessive battery drain. The problem is widespread. It's this problem: [XXX] As a result the vehicle is significantly less safe to drive. Tesla continually delays service appointments due to unavailability of parts. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

According to Tesla the AI4 computer experienced an internal short circuit. This has rendered all cameras including backup camera, GPS, parking sensors, and automatic wipers inoperable. The visibility out of the vehicle is very poor to the rear without the backup camera. Parking without the rear camera and parking sensors is difficult. Not having physical controls for the wipers makes turning them on/off and changing speeds difficult, causing a lot of drivers distraction.

After a software update pushed by Tesla, the AP4 computer in my 2024 Tesla Model Y shorted out, causing a complete failure of all safety 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 9. Auto headlight dim / Auto wiper system 10. BACK UP CAMERA RENDERED INOPERABLE 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. This system also initiates preconditioning of the battery (heats it up to be able to charge), so super charging is extremely slow without the gps system availability. 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. Rear visibility in the car is very limited without the federally required backup camera. 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.

All of the cameras on the vehicle are no longer working after the latest update. This means all sensors (even as simple as windshield wipers) do not work. All driver safety assistance does not work.
