2021 TESLA MODEL 3 Visibilitywiper Problems

HVAC system went out at 7500ish miles. It was repaired under warranty, and a "fix" was administered through software by tesla. My HVAC has gone out again at 84k miles FOR THE SAME REASON. about 77k miles after it was just repaired. Quick check online. this is still a very common issue. No heat creates a significant safety hazard due to lack of the ability to defrost the vehicle or frost building up on cold days.

-- Summarized Explanation The automatic windshield wiper system behaves unpredictably and creates unsafe driving conditions. Wipers frequently activate when there is no rain, operate at excessive speeds during light rain, and, most critically, fail to activate during active rainfall. These failures reduce driver visibility and increase the risk of a motor vehicle crash. Automatic wipers are forcibly enabled whenever cruise control or Autopilot is activated, regardless of weather conditions. This requires the driver to repeatedly adjust or disable the wipers while driving. Sudden transitions to maximum speed during light rain are distracting and divert attention from the roadway, increasing cognitive load during vehicle operation. -- Attempted Remedies •Replaced windshield wipers multiple times using different manufacturers •Cleaned forward-facing camera/rain detection area •Applied windshield water-repellent treatments •Installed approximately 30–50 over-the-air software updates over four years •Multiple inspections at Tesla-authorized service centers Tesla has consistently stated the system is operating “as intended,” despite...

The interior rearview mirror exhibits tiny bubbles around the edges and streaking or cloudiness within the layered structure of the auto-dimming (electrochromic) mirror. The problem has occurred in multiple potential replacement mirrors, indicating a design or manufacturing defect. The issue first appeared as small bubbles around the outer edge, then progressed to visible streaking and cloudiness within the mirror surface. These symptoms impair rear visibility, particularly at night or in bright light conditions, when glare and distortion are most severe. This creates a safety hazard by: 1) Obstructing the driver’s clear view of approaching vehicles. 2.) Reducing reaction time Increasing the risk of rear-end collisions or unsafe lane changes. 3.) It compromises overall driver situational awareness, especially in high-speed or congested traffic environments. The defect is not isolated to a single part. Defective mirrors have been retained for documentation and are available for inspection. Mirror replaced with same part number...

The defrost function on the computer went crazy and cracked the windshield in the morning, covered in snow. - It’s hard to see out of, and Tesla said it’s not covered even though it’s only 6 months old and to just drive it. - No, they want $1600 to look at it. I can’t get them to agree to look at it, but don’t give up. - no the defrost was slow and low, as winter is with no issues. So it snowed a lot in KC, MO. I keep my heat at 60 degrees and the fan on low. I unlocked my car with my phone to get some stuff out, but I started clearing off the back door stairs first to make a path. But only 10 minutes after unlocking it, I heard a loud pop. I thought it was electric, so I unplugged it and got in...

Tesla ADAS detects non existent objects and issues collision alerts and phantom brakes randomly if there is no cars in front of the Tesla, braking abruptly and almost getting me into rear end accidents. Tesla ADAS freaks out when making lane changes randomly, shaking violently and giving the driver and its passengers a fishtailing simulation. Auto wiper triggers randomly while it's sunny, distracting the driver and forcing an interaction on the center console to stop it. Auto wiper cannot be turned off as it reengages upon using Tesla ADAS. The rear view camera lags. It stutters and shows me a delayed view. Compounded by the Model 3's very small rear view mirrors and side mirrors, this is incredibly dangerous as I have no way of gaining sufficient visibility of the back of the car. Tesla service told me this is all normal.

The contact owns a 2021 Tesla Model 3. The contact stated while driving in the rain, there was an auto rain-sensing feature on the vehicle that was inoperable. The contact stated that the front windshield wipers did not automatically turn on while it was raining and that the auto rain-sensing feature worked intermittently. The contact stated that the manufacturer was made aware of the unreliability of the auto rain-sensing feature, but stated it was a Beta feature. The contact stated that the risk was that there was no physical control for the front windshield wipers causing a safety issue because the contact could not engage the wipers safely when driving as it was not readily accessible via the entertainment panel when the auto rain-sensing was inoperable. No warning light was illuminated. The vehicle was diagnosed, but not repaired because there was no fix. The manufacturer was made aware of the...

Auto windshield wipers do not turn on often when raining or misting. I constantly have to change the settings which takes my eyes off the road often. Very poor and unsafe system

Auto wipers do not speed up in heavy rain forcing me to manually change the speed which can be dangerous while driving on the highway in heavy rain.

The cruse control is unable to keep its speed and sometimes the vehicule breaks suddently on the highway, especially when the road is wet. The cameras are obstructed by mist or other dirt and the system does not work properly. Related to this problem, the wipers are dangerous to operate. When the cruse control is engaged, then the wipers are forced to automatic mode, which does not work properly. It could start to swipe the dirty mist and actually reduce visibility. Operating the wipers with the touch screen is a hazard, forcing the driver to leave the eyes from the road. I contacted Tesla about these problems last year and the company did nothing. Even worst, on their new cars they removed the stalks completely, which is a non sens. The NHTSA has to intervene.

Heating failed in -10 temperature for approx 40 miles. Window became ice covered and would not clear. Interior of car was 33 degrees and heat came back on when plugged into charger.

This same event has happened to me approximately 3-4 times since owning the vehicle. It occurs randomly without warning. The vehicle screen will randomly and suddenly freeze up and render itself inoperable. Eventually, the screen will reset itself or I will have to manually force a reset. After about 5-10 minutes, the screen will reset and the problem goes away. During the 5-10 minutes of the screen not operating, I cannot see or change any of the vehicles controls; loss of HVAC control, cannot turn on windshield wipers, cannot see vehicle speed, don't know if turn signals are on/off (also lose audible sounds when turn signals are on) are the major safety related losses; you essentially lose all control over the vehicle settings/controls. Vehicle continues to drive as normal, and all functions are restored after reset is complete.

AC/Heat pump total failure at 18,317 miles. Due to cold weather in Michigan and simply running the car, the heat pump went out entirely which creates the climate control in the vehicle. This caused dangerous driving conditions since the windows could not be defogged and the vehicle was below freezing temperatures inside. The service agents I spoke with seemed to understand this was a common occurrence in cold weather climates. The reason I am reporting this, is although mine was replaced at no cost to me under warranty, this is a manufacturing oversight and needs to be addressed by the company. This can cause very unsafe driving conditions for many people, and cost thousands of dollars in repairs all because they sell a vehicle that has parts not suitable for the climates they operate in.

The heat pump failed in 12/2022. The defroster would not work and heating was an issue. I encountered 2 dangerous situations in snowstorms where I could not see out the window and the heating was inconsistent and difficult to control.This was fixed by Tesla. The heat pump failed again (less than a month later). I was told today that there was an ice buildup in the coils possibly due to car wash (?). This problem, I am afraid, is going to continue.

The supermanifold failed, causing the front defroster to not work properly, resulting in loss of visibility in freezing temperatures. This is a common problem with 2021/2022 model 3/model y with the new heat pump that was supposed to be fixed with a software update, but was not. I now have a $3900 repair bill on a 1 year old car with 56,000 miles. The warranty expired at 50,000 miles. The failure was not a result of negligence.

I'm getting a notification that says " cabin climate control system requires service cabin heating/cooling limited or unavailable". As a result of this failure the defroster is not working properly. The windshield defroster will only blow cold air very slowly. This causes the windshield to fog up very quickly in cold temperatures. I cannot see out of the windshield properly.

https://youtube.com/channel/UCNkrwnR_lAKd4neLwYAbugA My YouTube channel has 13 videos about Tesla safety concerns. They are the only videos on my channel. The minutes long clips show what happens when the mainframe screen goes black, dies out or powers down while driving. Listed from memory are the following concerns associated with the Tesla ‘Black Screen of Death’: 1. No energy/distance shown 2. Glove box is inaccessible 3. Front trunk ‘Frunk’ cannot be opened 4. Proof of signalling is gone 5. Proof of low vs high beam is gone 6. Changing of wiper speed is gone 7. Access to heating/Air-Con is gone 8. Back up camera is obsolete 9. Cameras used when signalling are missing 10. Speedometer is not visible 11. Odometer is missing (have never found it on screen when running anyways!) 12 Air pressure indication is gone 13 GPS is obsolete From memory that is all I have to add. Imagine everything...

Tesla offers a blind spot camera, standard on the vehicle, which activates automatically when the turn-signal is active on the appropriate side. The blind-spot camera feed appears on the center screen. The feed comes from each of the side cameras mounted to the external portion of the car. Since the side turn-signal is mounted right above the same blind-spot cameras, the light from the turn-signal often 'bleeds' into the camera feed used by the driver to determine if the appropriate lane is clear. At night, this causes the blind-spot camera video difficult to view since the video feed alternates between 'normal' video and a bright, flushed out video, matching the turn-signal timer. The end result is often times I, the driver having difficulty observing cars on the side of my vehicle at night. More specifically, several times I have missed the headlights of cars in the lane next to me...

While driving from Austin to Nashville, during the last, dark part of our drive, we hit rain. The Auto windshield wiper setting did not work, so I had my passenger help with selecting wiper speeds as the wiper speed control is difficult and distracting to use while driving. We tried the Auto setting a couple more times to see if there was any change, and noticed that the wipers would turn on when we drove under a light, then off again when the there was no light. We tested this a few more times and it appears that the Auto wiper setting only works in well-lit settings (i.e. when it's not raining), and does not work in the dark. It is possible to click a button on the left stalk to trigger a single wipe, but this is ineffective in anything beyond light rain. Due to the inaccessibility of the...

Since the V11 user interface update, when you put the car into reverse, the rear camera sometimes does not show up, or often shows up only after a delay. Sometimes the delay is just a second or two, other times it is a minute or seems to hang forever. Today I was parked in front of my kid's school dropoff zone, and needed to back up after they got out to leave. When I went into reverse the cameras were just black and stayed that way. This was especially worrying in this scenario since small children could be walking behind me that I wouldn't be able to see without the camera. This was never a problem until the V11 user interface update, which also causes other safety problems, by burying important functions behind menus. For instance you now have to dig into a menu and reach all the way to...

In December, Tesla released a software update that made Model 3 and Model Y cars unsafe to operate. They hid the defroster buttons and many other important controls behind menus that require multiple touchscreen presses to operate. This is unsafe to do while driving and as such we don't drive this car if the weather is at all suspect. The interface for safely operating a car should not rely on taking your eyes off the road to navigate touchscreen menus. Tesla has refused to roll back the software update and has promised a future update in the future to address some of these concerns. It's been over a month now. This needs immediate attention.

My vehicle has a VCFRONT_A447 error code and will not heat up. With temperatures as low as -20 and highs of 25 not only is just the temperature potentially deadly but im unable to defog my windshield without freezing. I feel my car is entirely unsafe to drive.

The windshield wipers are controlled by a sensor and the computer. Unfortunately, they come on too slowly. Several times I have been driving in the rain, waiting for the windshield wipers to start clearing the windshield. Each time, the rain on the windshield has gotten so bad that I was unable to see anything out my windshield. If the car in front had braked quickly, or if some pedestrian was trying to cross the street, I would not have known. I tried to tell this to a Tesla service rep, but was told the wipers are controlled by the computer and there is nothing they can do.

Driving on the beltway around Washington DC the weather conditions were variable and the revised user interface in version 11 of the Model 3 software made changing the defroster settings dangerous while in traffic. Previously, it was a single icon on the control screen. Now it requires a push of an icon and a search for the correct controls and adjustments.

The heat stops working at cold conditions. Many other users have reported this problem, after going into service I was told there is a sensor that is out in the open behind the bumper that when exposed to snow and rain can freeze and causes heat to stop working. I have experienced this myself when going on a trip back home from upstate NY to NC , I had no heat with temps outside being at 3 degrees F , not only was the car extremely cold causing me and my wife to get sick , but you can not use the defrost because there is no heat. So there is absolutely no visibility since there’s frost on all windows that you cant do anything about.

Tesla in the December 2021 V11 software update as made the car's common control user interface unsafe. Critical controls, such as defrost and climate control, as well as many others (like trip, tire pressure, heated seats, windshield wipers) , are now only accessible by hunting through menus - - all which require the driver to turn their eyes off the road for longer periods of time than the previous user interface. Font sizes have also been made much smaller which will cause readability issues. This is a road hazard and needs to be addressed, and there is no option available to downgrade to the safer user interface. Please require Tesla to perform an over the air recall for this UI to correct these safety issues.

Tesla pushed out a new user interface over Christmas. The new interface buries the wiper controls and defrost controls under sub-menus and you can no longer quickly access them while driving. It takes multiple clicks and requires you removing your eyes from the road for a long time. Furthermore, there is no way to revert back to their old interface.

Windshield has highly visible internal reflections resulting in vertical ghosting in high contrast situations such as headlights brake lights and even on sunny days service center said it was within acceptable tolerance but it greatly diminishes the clarity of vision through the windshield. Haven't seen anything like it in the four other cars manufactured across two decades that I've driven regularly. Dangerous design or manufacturing defect.

HEAT NO LONGER WORKS IN THE CAR'S CLIMATE CONTROL. THIS APPARENTLY IS TIED TO FAULTY HUMIDITY AND TEMPERATURE SENSORS THAT MUST WORK PROPERLY FOR THE HEATING SYSTEM TO WORK, AND TESLA SERVICE CENTERS ARE AWARE OF THIS YET ARE NOT PROACTIVELY REPLACING THEM. THIS IS A SAFETY ISSUE IN COLD CLIMATES SINCE THE WINDSHIELD DEFROST NO LONGER WORKS, AND THE CAR IS UNSAFE TO DRIVE OVERALL IN COLD TEMPERATURES WITHOUT FUNCTIONAL HEAT. THIS ISSUE APPEARS TO BE RESTRICTED TO THE 2020/2021 MODEL 3/YS WITH THE HEAT PUMP THAT REQUIRE THESE SENSORS TO FUNCTION PROPERLY. ANOTHER SYMPTOM IS THE CLIMATE SCREEN DISPLAYS AN ERROR MESSAGE OF "CLIMATE KEEPER IS UNAVAILABLE DUE TO A SYSTEM FAULT."
