Right rear passenger window opens when left knee inadvertently hits down window button while driving

Right rear passenger window opens when left knee inadvertently hits down window button while driving

This may seem weird but it has happened to me more than 20 times in the two weeks that I have owned the vehicle. And I have changed the seat settings twice. Just curious if it has happened to anyone else. There does not appear to be a way to prevent the button from working. It works too well!

Huh. Never happened to me. I'm 6'3' with lots of leg, so my knees generally bang into anything available. ;-)

djwill | October 1, 2013

Happens to me quite a bit. Have to remind leg not to go there.

thatheard | October 1, 2013

This happens to me a lot. I'm also 6'3". I've learned to be careful, but still relax into the button on occasion. I always assumed it's because of the flaps on the leg pockets of my uniform though.

Happen to me while raining…my wife was not happy with the unexpected “shower”

At first I thought it was a malfunction but then when I did it 2 more times, I saw that my knee was causing it….. :) lol

Well there must be some way we can get Tesla to deal with this issue. It is obviously a design flaw.

Theresa | October 1, 2013

I have not had that issue but I do change the radio stations quite frequently when turning as the button is very easy to hit when turning the steering wheel. The first few times it happened I thought I had a software bug. There should be a little more indentation needed to push the up/down station button.

It happened to me a number of times. Spooky. I found a solution though: I don't put my knee there.

pablodds | October 1, 2013

It happens to me too. I have adjusted the seat position, but mainly just focused on not putting my knee there. It is something that could be improved in the interior deign.

I bet it's happened to tttttesla and I'm sure he's not happy about it, either.

bdukov | October 1, 2013

Happens to me as well, especially when turning hard right!!! I just have to be aware of it, as my left leg likes to relax in an angled out position.

bdukov | October 1, 2013

Happens to me as well except it is the right front window, especially when turning hard right!!! I just have to be aware of it, as my left leg likes to relax in an angled out position.

T3SLA | October 1, 2013

The window goes down when I push the button.

DickB | October 1, 2013

It's the right front window that goes down for me. It happens almost every week at least once. Had the car since last December.

bbryant | October 1, 2013

happens to me, 5 10 need to rest the leg and the switch is trigered.
would like to see the techs give us a switch to disable the rear windows....
then duct tape may be the answer

David70 | October 1, 2013

It has happened to me a few times. No big deal if I forget to avoid putting my knee there, but it has confused/surprised me on occasion.

wcalvin | October 2, 2013

Sure it is pressure atop the button? Could it be sideways pressure moving wires?

Bighorn | October 2, 2013

Do all Model Ses have a dead pedal or just the P? If so, there may be a negative correlation with leg leaning against the door.

Don Schmidt | October 2, 2013

Am I missing something here? The window goes down when you put pressure on the down window button? What do you want to happen when putting presure on the down window button?

Push the lock button for the rear windows and this won't happen. That's what I did.

mervyn | October 4, 2013

Don you are missing the point that everybody is making. It is that in a normal comfortable sitting position peoples knees are touching the button - bad design location.

Jdpilot locking the rear window only prevents the controls in the back from opening the window but not the driver. I wonder if Tesla could put out a software update whereby activating the rear window lock also prevented it opening from the front.

Its all very well saying, "don't put your knee there". If I spend $100+k on a car, why should I have to lose my most natural sitting position.

jonlivesay | October 4, 2013

I tried to do this, can't figure out how you do it? Must be lacking a vital part of my knee.

tpmeyer | October 4, 2013


Yes you are missing something.

dglauz | October 4, 2013

I am 5'9" and managed to open the front right window using my knee. Had to pick my foot up off the floor and try. My seat is too far forward to get the back window. I can see this as a problem for someone with long legs. normally my knee falls to the door in front of the buttons.

Ergonomics generally designs around the typical sized person. I am sure that those of you that are extra tall and extra short encounter problems all over the place, as well as in the car.

tes-s | October 4, 2013

Happens to me, but rarely when driving. Usually when just sitting.

mrspaghetti | October 4, 2013

I noticed that my knee was dangerously close to the window controls and worried about it a little while I had it, but it never actually triggered the button.

riceuguy | October 4, 2013

Could be worse...I am 5'5" and with my seat as far forward as it needs to be, do you know how hard it is to use the cupholders?! But hey, I never even come close to accidentally opening the windows!

Brian H | October 5, 2013

It only happens to the physically abnormal.

rdalcanto | October 5, 2013

I'm 6ft, 34 inch inseem. I just went into the garage, and there was no way I could hit the button with my knee to make the window go down. Are you crossing your legs when you drive, so your left knee can flop down onto the buttons somehow?!? Sounds like you need to adjust your driving position.

EESROCK | October 5, 2013

My husband has accidentally opened the rear window with his knee several times. It's never happened when I'm driving, so I'm always surprised when he does it. Made me wonder what was wrong with his anatomy. Glad to know it's not just him.

PBEndo | October 5, 2013

Is there more than one design for the window controls? I am just over 6'2" and I can't even come close to depressing the buttons with my knee in any reasonable position.

Btermanini | October 5, 2013

It happened to me several times when turning right hard with some G force, I suppose because the seats are not very supportive.

Captain_Zap | October 5, 2013

My spouse is over 6' tall and robust. He just went to the garage and tried to open the rear window with his knee. He managed to do it but it was quite a contortion.

I tried to open the window with my knee while in the driver's seat. It wasn't possible.

DallasTXModelS | October 5, 2013

So the button does what it is supposed to do. You are not supposed to rest your knee against the armrest.

Xerogas | October 5, 2013

Happens to me quite often, too. I'm 6'3", and am seeing a trend here: if you're 6'3" and all legs, then this seems to happen more often.

I had to adjust where I put my right heel for the accelerator, too, and it's much more comfortable now that I've found the sweet spot.

DallasTXModelS | October 6, 2013

If your left foot is on the deadpedal and not flat on the floorboard in front of your seat, your knee should not hit the window conrtols.

DonS | October 7, 2013

I'm 5'-11" and I cannot figure out how it is possible to hit the button with your knee. I moved the seat around a bit and I couldn't find anyplace that looked close.

wcalvin | October 7, 2013

Might consider trying some shim stock that is thin enough to fit the thin slot on the right edge of the lever switch. Fold it over on top to protect fingers. Something like a single-edged razor blade with the sharp edge filed off.

Tesla could probably do a snap-in plastic runner for the right side of that switch band.

chrisdl | October 7, 2013

Now if someone's sitting in your lap, they might press the window controls with their knee, though. ... And turn on the wipers... And honk the horn.

Brian H | October 8, 2013

getting a bit carried away imagining an active lap passenger, there? ;P
