Wiper problems of the 2021 Tesla Model Y - part 2

Wiper failure when set to automatic (rain-sensing) when vision system shut down due to poor visibility. A little background: I've been driving for 50+ years, about 1. 5m total miles, most of it commuting. I'm a software engineer with 45+ years of experience, mostly in embedded systems. Problem drive: most settings, including headlights and wipers, on auto. Autopilot was on. Drove into a heavy rainstorm, auto wipers worked well, speeding up until they were on high. Traffic speed dropped from 70+ to less than 35 due to rain. Drove into a band of torrential rain. Saw a pop-up on the screen that said something like autopilot turning off due to diminished visibility. Autopilot (speed control) then turned off. Then the wipers shut off. Let's see, guy designing vision system: can't figure out anything from camera images, so let's warn user and shut off stuff that relies on the camera. Like autopilot. Wipers? leave them in the last state? nah, turn off the enable signal to the auto wiper state, too. Torrential downpour, almost no visibility, and my wipers just shut off. I frantically kept pressing the wiper button on the turn signal stalk to force a couple of swipes and force the wiper pop-up menu, then take my eyes off the road with possibly someone stopping right in front of me (yes, I slowed down) to do hand-eye coordination on the wiper pop-up to hit the manual setting full speed button! related to Tesla model s/x recall for touchscreen failure disabling defog/defrost. Proper design requires hard controls (not just touchscreen) for safety-critical items, like lights, wipers, defog/defrost. That's why a hard control for hazard flashers is required. I've spent years designing life-critical medical systems. They all have hazard mitigation matrix sections - analyze possible fault modes, assign chance of happening and severity of impact if they happen, then have a mitigation strategy. This seems to be a system design flaw.

We picked up out new Model Y on 2/13/2021 from minneapolis, due to living in iowa and that being the closest store. After leaving minneapolis, the interior heat quit working. We messed with the controls all we could and it would not start again. The exterior temperature was in the negative teens. At one point on the 2 hour 45 minute drive home the interior cabin temperature was in the single didgets. It continues to not work correctly from the interior controls. I was unable to get ahold of anyone at Tesla to find a better solution other than just getting home. Online research says that this is an issue many people have come across that I was not made aware of. The windows of the vehicle were beginning to frost over during our drive home. We restarted the vehicle multiple times, and have been able to get the car to warm by using the Tesla app on our phones, but once we start driving the heater stops working. I feel it is unacceptable to have received a new vehicle with 6 miles on the odometer in the upper midwest with a heater that does not work as intended.

My defroster has failed for the second time. The car fails to provide heat in cold temperatures, suddenly and without warning. This presents a dangerous condition when driving in winter climates and results in the windshield icing up inside and out. I have been in constant contact with the dealer and they have replaced sensors. Now they have stated that the car performs as it should, and is made for warmer climates. The last time the failure took place, I was driving in a snowstorm and the windshield iced over, bad enough that the windshield wipers froze in place. I am also being told that the car must warm up for 45 minutes prior to driving, due to this condition. My car is no longer drivable when the tempi tire is below 15f without reasonable risk of becoming impaired. I have requested the service department to repair my car again, they have refused, stating it is normal operation for this model. Again, when on hi defrost in temperatures below 15f, the cars climate control cannot supply enough heat to properly keep the windshield clear.

Heat doesn't work on new Model Ys. For cold climates this should be a huge issue. Cannot defrost windows. Can't get the cabin heat on could result in hypothermia if tire goes flat. This is a wide spread issue, apparently faulty sensors, and they're still producing with known problem.

I took delivery of a Model Y Dec 27, 2020 and was concerned re the diver's side view mirror. I also enquired when a service call was needed for an unrelated issue soon after delivery. The mirror adjustments do not allow visualization of the lane on the left or to the rear without bending to the side and craning my neck. It creates an unsafe situation while driving and Tesla says there is nothing wrong. I have tried every possible adjustment and it is a clear design flaw. I am 6 feet tall, so I am sure I am not alone in this issue.

The driver side mirror cannot extend to allow normal side view visibility. I am only 5'8" and at full outward electrical motor stop, about 1/3 of the mirror shows the car body. I have 55yrs of driving and never had a car with this limit. My wife, at 5'2" is able to get proper adjustment.

The driver side mirror does not got far left or up enough. I am 5'11. I had another Model Y before this without the auto dimming mirrors. Did not have an issue at all with the mirror. Right now the mirrors I cannot see anything on my next lane on driver side. Nearly hit someone already because of this. Not sure if it is mirror assembly or the glass itself. But I imagine most likely something to do with how it is install. I think the mirror's initial setting is not placed correctly so the motor can't go past anywhere. The mirror also doesn't sit flush with the door and trim of the car.

Driver side mirror won't go outward and up enough. I can't see anything in the next lane. Really dangerous for tall people like 6'00".

The driver side mirror cannot be angled left enough to display properly what's on the left side of the vehicle. As such, more than 1/3 of the mirror displays the car itself instead of potential other cars or objects on the rear left (see attached picture). There is a way to angle further the left the mirror if it is angled down. However this leads to a worst situation where we see only the ground next to the vehicle instead of cars or objects on the rear left. This is a recent issue introduced in Model Ys with auto-dimming mirrors only and I believe this will cause accidents if not already if Tesla does not release a fix for this issue.

Tesla added new auto-dimming mirrors if you adjust for a person 5'10" or above the mirrors don't adjust to see the left lane. It points down and to the right. I took delivery of vehicle and made formal complaint to delivery team on 11/27/2020. I went with senior service tech at the service center and all new delivery with these new mirrors do not adjust up and to the left for taller drivers. I have a previous VIN without new auto dimming mirrors and does not have this safety issue. Have discussed with a multitude of owners with new mirrors and it is a very common issue. I have also attached others vehicles with same issue along with mine. . Read more...
