2020 Tesla Model Y visibility problems

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.

I have a Tesla Model Y and a Model 3. Both of them 2020 year purchased. The miles on Model Y is 96K and 43K respectively. In Feb 2025, my Model Y windshield had cracked and I had made a Tesla Insurance claim and paid the 500$ deductible and got it replaced. Now, in May 1st week, the same Model Y's windshield is cracked. When I take to Tesla service center, they say that its because of an external impact and so, they can't consider a warranty claim and I have to make another payment for this. That's the first thing. Now, with my Model 3, there is a crack developing on the rear windshield. I understand from Tesla that it has to be replaced too. I had a chat with Safelite auto glass company technician and he said that Tesla's glasses are too thin to accmmodate sensors and thats why this is happening repeatedly.

Component or System Failure: The HVAC system, specifically the compressor and supermanifold, failed on my 2020 Tesla Model Y. Tesla retained the replaced components during service, so they are not available for inspection. Safety Risk: This failure caused a loss of cabin heating and prevented proper windshield/window defrosting during cold weather, severely impairing visibility and creating unsafe driving conditions. Critically, this system also regulates battery heating. Without it, battery performance in cold temperatures can be compromised, reducing driving range, impairing charging capability, and risking vehicle operability in freezing conditions. Problem Confirmation: Tesla service technicians diagnosed and confirmed failure of the compressor and supermanifold. Full replacement was required to restore proper HVAC and battery heating functions. Inspections Conducted: The vehicle was inspected by Tesla service both before and after the failure. Prior to my ownership, the vehicle had been brought in by a family member (prior owner) for HVAC performance concerns. HVAC issues reappeared around 28,000 miles, but I was unable to immediately schedule repairs due to the Tesla Service Center being approximately 1 hour and 15 minutes away and personal scheduling constraints. The vehicle was finally repaired on April 24, 2025, at 38,511 miles. Warning Indicators: Before the failure, HVAC symptoms included inconsistent heating, occasional HVAC warnings, and degraded cold weather performance. Additional Context: I was required to pay $2,992.89 for the repair out of pocket, as the vehicle was just outside of warranty. Due to this failure, I drove for an extended time without reliable cabin heat, defrosting, or proper battery heating in winter conditions, exposing me to serious safety risks. Tesla has acknowledged HVAC component contamination issues in official service bulletins, suggesting a known systemic problem.

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.

During phone calls, the system would start making sparking noises and stall the calls. While navigation was input parts of the screen would disappear. While backing up, the rear cameras would freeze and stall. The rear camera freezing had caused us to get into an accident, and caused us to have 4 near misses. When I was trying to download the latest software release, the software download froze and never downloaded. I started to drive to the Tesla dealership and as I was doing so, the screen picture of my vehicle disappeared along with the gear shift indicator, the surrounding cameras failed. Then when I put on my turn signal, the sound disappeared. Then eventually the indicator disappeared. The entire screen froze with no information, and then went black while I was driving to the Tesla dealership. The system was black and finally did a reboot after 4 minutes, all while I had no display of my speed. I took it into the dealership, and the checkin girl was concerned about the safety and gave me a loaner. The technician was not really concerned and said it was not able to replicate the issue and said there was no safety issue as you can still drive the car. This is not correct as you do not have the speed indication when your screen freezes or goes black. I sent them pictures as the screen kept doing one thing after the other in a matter on one drive from my home to the dealership in 15 minutes. This is similar to the other recalls that Tesla had to make on the model S and the Model X and some model Y's. This should have been taken care of under the current recalls for the infotainment system that the other models years were facing as it is giving the same issues on my model.

When reversing, the backup camera does not display realtime video. It will display footage that is paused or behind. The pedestrian warning sound occasionally does not "load" when backing up. This has lead to near miss collisions when reversing and has put pedestrians at risk of not hearing the vehicle in motion, whilst being unable to see realtime footage below the rear tailgate. When the car is left in a parking lot or driveway for several hours, the camera will not "load" completely and leads to this condition. It cannot be reproduced unless the car has been sitting for several hours, as most driving events begin. The vehicle was inspected on 4/25/2023 by the manufacturer and have stated the vehicle is operating as expected. The symptoms cannot be captured by an image, only video.

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.

Windshield cracked from midway of windshield to the bottom. I have heard of/seen a significant number of similar cracks on Tesla Model Y.
