2021 Tesla Model 3 Window & Wiper Problems

Owner reports

Selected complaints filed with NHTSA by 2021 Tesla Model 3 owners, lightly cleaned up (personal details are redacted by NHTSA).

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 to leave and immediately was shocked to see and hear the heater on so high I didn't know it went to that level. It had to have been 100 degrees in the car then before I even sat down... …

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 power liftgate strut failed in normal use and bent the trunk liftgate, which now strikes the rear glass every time the trunk opens or closes. The vehicle has not been in a crash and the trunk was not obstructed or misused. The driver-side power strut stopped operating and the trunk would not open or close properly. On [redacted] Tesla Service ([redacted]) inspected the vehicle. The service record states the liftgate power strut was stuck in the closed position because the liftgate is bent to the right, hitting the glass on opening and closing. Tesla installed a new power strut, then removed it. A service message stated the hinge was replaced and the liftgate remains far out of alignment; the service record does not list a hinge replacement. The visit was marked resolved. The power trunk no longer functions. …

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. …

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. …

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. …

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.

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.

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 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.
