2020 Tesla Model Y: windshield wiper failure

Filed Feb 2, 2026 · Electrical, Visibility · OR

Observed intermittent center display/infotainment computer (MCU) crashes/reboots where the center display becomes blank and then restarts. In recorded events, when reverse was selected during an MCU reboot interval, the rearview camera image did not display until the reboot completed. Recorded rear camera unavailability during reverse was approximately 10–17 seconds. MCU crash/reboot behavior was observed to be repeatable, including predictable occurrence while the vehicle was in the built-in Service Mode. After a factory reset, repeated/double boot behavior was also observed. Additional observations: - With the turn signal activated, light leakage was observed in the side repeater camera image (glare/bloom present in the camera view). - With each windshield wiper sweep, the forward camera image was observed to briefly flicker to a purple/green distorted state and then return to normal. - During driving, the on-screen message “Auto Lane Change unavailable” was observed. A separate rear camera symptom has also been observed: intermittent freezing/stale frames (image appears not to update). This rear camera freeze behavior has not yet been captured on video. These conditions have been documented by video/screenshots and reported to the manufacturer/service center for inspection/diagnosis. No crash or injury occurred. The vehicle is currently located at the manufacturer’s service center and is available for inspection upon request.

My 2020 Tesla Model Y Long Range/AWD vehicle has 46,000 miles and can no longer recharge its battery (engine) with an approved charger (L2) due to a commonly failed part inside the battery. This part is called PCS (Power Conversion System). This device attached to the Tesla battery is used to convert power from a charger which is AC (household alternating current) into DC (Direct Current) the battery can understand. This error appeared for the first time on [XXX] at [XXX]. This critical part has failed in thousands of Tesla vehicles, some multiple times easily verified by thousands of customer complaints online. The PCS is NOT a consumable part - such as a tire, wiper blades, brake pads, etc. There is nothing the vehicle Owner can do to prevent the PCS failure. The Cost to repair/replace the PCS part(s) is ~ $3,000 and may fail again after replacement. As required by Tesla, I scheduled a service appointment through their phone app, and received an estimate of ~$280.00 to repair my vehicle on June 26, 2025 at the Irvine, CA Tesla Service Center 2801 Barranca Pkwy. After diagnosis, I was informed the cost to fix/repair the PCS part in my vehicle so that I could charge and drive it, would be ~$3,000. The Manager Ryan Sutherland (949) 404-2989, further stated the repair would not be covered under my Vehicle Tesla Warranty (Tesla battery or drive unit warranty that does not expire until [XXX]). I tried to contact Tesla corporate for assistance at [email protected] and did not receive a response but instead was contacted by service manager Ryan Sutherland via email confirming Tesla's warranty position. Tesla is essentially the only service/repair resource available for these vehicles. This repair is obviously due to a faulty/defective PCS or faulty design by Tesla affecting thousands of vehicles and should covered under my vehicle warranty so that it can be driven.

Tesla has automatic windshield wipers that are supposed to engage at various wiper speeds when rain is detected. The system does not activate soon enough or at an appropriate speed. Example: In rain situations on a highway when passing a large truck, the amount of spray on the windshield will completely occlude visibility at critical moments. Also if driving through a neighborhood in a drizzle, when kids are walking to school, the wipers do not adjust properly occluding visibility at critical moment’s. Potential solution : In both cases above the Tesla cameras detect the truck and the pedestrians, this data should be used to increase wiper activation and frequency. Tesla also collects user input data from drivers and perhaps collecting data when drivers activate their wipers compared to what the cameras are seeing will help adjust the wiper activation algorithm.

I am writing to formally file a complaint against Tesla, Inc. concerning a significant issue that has arisen following a software update issued to Model Y and Model 3 vehicles in early December. I am a Tesla Model Y owner, and following this update, I have experienced complete failure of critical vehicle systems including cameras, navigation, lane departure warnings, auto braking, forward collision warning, adaptive cruise control, windshield wipers, self-driving features, and car location data. The malfunction of these essential features not only compromises the safety and functionality of the vehicle but also indicates a severe underlying problem with the vehicle's computer system. The cost to replace the affected computer in my vehicle amounted to $2,400. However, upon reviewing discussions on Tesla forums, I have discovered that this is not an isolated incident; numerous other owners are facing similar failures, with some repair bills exceeding $3,000. Given the widespread nature of these issues and their chronological association with the December software update, there appears to be a high correlation between the update and the catastrophic failure of the vehicle computers. The financial burden of these repairs has unjustly fallen on consumers, although it is my belief that Tesla should be held accountable for these failures, given the direct link to their software update. I urge the federal safety agency to investigate this matter thoroughly. It is critical to ascertain whether the December software update directly caused the failures of the vehicle's computer systems and to ensure that Tesla takes appropriate responsibility for the safety and reliability of their vehicles. This includes compensating owners for the costs incurred due to these failures and implementing measures to prevent such incidents in the future. Thank you for your attention to this serious matter.

A recent software change removed the automatic activation of headlights with wipers. Headlights on with wipers is the law in most states and a common sense practice. However, with the removal of the automatic activation, you are forced to tap into several sub menus on the touchscreen in order to manually activate the head lights, all while driving in less than ideal conditions.

Tesla recently release their version 11 user interface. This update took a lot of safety features and put them behind menus. Windshield wipers, defrosters, seat warmers were all easily accessible in the previous version. Now they are wall hidden behind menus. If you need one of these features while driving, you get distracted while trying to find it which is dangerous. But these features are necessary to use while driving.
