Falcon Wing Doors - sensors not foolproof

Falcon Wing Doors - sensors not foolproof

An embarrassing moment for the Tesla Model X salesman demonstrating the Model X falcon wing doors to prospective customers. The model X was parked next to my Model S which had an open rear door. The salesman was about to demonstrate the safety sensors on the falcon wing doors of the Model X and I asked if it would be safe for me to leave my door open. The salesman claimed that it would not be a problem and that my door would be safe. Not so! The sensors did not pick up by Model S rear door and the Model X falcon wing door struck my car. Fortunately no damage that I can see. But it does beg the question what if it was a baby in a pram. A very embarrassed salesman claiming he had never seen it happen before and that he would look into it. The door sensors on the Model X are not totally foolproof! It is ironic that it picked its brother model S to hit.

Sorry but I have to say it.
How is this news to any MX owners?

So far, I haven't seen a demonstration with a rear door open on adjacent cars.

May be the salesman should stick to conventional scripted demonstration scenario and not to go off script just because of a suggestion of a customer :)

Now, this happened, can Tesla fix this kind of scenario?

Reminds me of this salesman demo of a Volvo's automatic brakes that didn't go so well: https://www.youtube.com/watch?v=AsTxS6tg6xc (only 20 seconds).

@Tam - fix is to tell Tesla employees not to do that kind of a demo!

What? I do it all of the times. I parked in my very packed garage and the FWD opens only about 1ft gap just wide enough for me to slide in the seat. I demo it often too. I parked about 8-9" away from my cousin's brand-new Toyota $41K van and my FWD opens just perfectly fine. Only 1 times I could not do the demo successfully is when I (very skinny) stood in the way but turn side way, and the door hit me. I am pretty sure if I didn't turn side way, it would have seen be better.

@PoloX 3 times a charm, I've done it before too :-)

Yesterday, my FWD was up in the garage. My wife decided to open the garage door. I didn't even think about it. Half way into it, she asked if it is OK and she didn't even bother to stop it. By the time she told me, I finally realized it and woke up and, looked up, the garage door traveled just about 2" above my FWD.

No need to buy sensor or switches or anything to "sense" the FWD are up and unplug the garage door power....etc as some had done. Just find a piece of foam or something like a piece of carton box cutout and place /hang it at the same hight as the garage door when opened right above the FWD sensor. The sensor is on the roof, in between the 2 FWDs. Simple, quick, cheap, and most effective. With the high tech sensor/relay...method, after each time it triggers, you would have to reset it. This option, you do nothing. :o)

@poloX - My read of the OP's description has the X next to a S with the S car door open, perhaps the door edge an inch from the X FWD. I can see that depending on where the S door is in relation to the sensor, the X FWD sensor may not see anything in the way and start to open. This is quite different than your scenario where the X FWD sensor "sees" a large flat surface of another car next to it and can properly open if there is enough space or remain closed if there is not enough space.

I wouldn't know. I'm not a fool. I take the same precaution as and won't do anything that I would not with regular manual doors. Never had a problem.

poloX | February 26, 2017

The S with an open door, the door is structure. Same as my cousin's Van next to my FWD. Or in my garage, shelves...wall...etc. Same thing, other objects in its way. My WFD does sense these things and open differently and stops about 3" before these objects.

And I just share a trick about hanging something above the sensor between the FWDs to fool the car so it won't open the FWDs too high. This is a tip to not to be hit by the garage door.

If I stand next to my FWDs they just push me out of the way.
One time I forgot to look up at the low overhead beams in the Tampa parking garage before I opened the rear hatch. To my delight it stopped before it hit the beam.

George your doors are defective. Tesla fixed mine to perfection.

georgehawley.fl.us | February 28, 2017

@X90D: Thanks. I figured that out but there is not enough urgency to compel me to do the 100 mile round trip to the Tampa SC. I'm thinking of waiting until my first annual service appointment in May to have them tune the doors.
I was surprised at the rear hatch feature, though. That was neat.

Model - X | February 28, 2017

My rear hatch failed as well. All fixed. Took them forever but it got done.

My falcon wing door attempted to close on me while I was vacuuming the back floor board. Granted, the car was wet from a wash, but, it was a bit scary to have the door hit my legs before stopping. Water seems to be an issue for the sensor.

patswin | March 20, 2017

Jerry, where your keys in your pocket at the time? I ask because I know I have accidentally closed the doors while cleaning car before as well as when getting into the car. Just sitting in it parked I even managed to put it in summons mode. All this when my fob was in my pocket. When I keep it out of my pocket I never have these accidental closings

PedanticOne | March 20, 2017

I have one-click close turned off and instead just use fob triple-click to close them all. Much safer.

Rear Cargo Hatch Sensor??? Not functional on my X, at least for avoiding an obstacle behind the car.

I park my X in the garage with just about 12-14 inches clearance between rear bumper and garage door to allow for front walking clearance in my relatively shallow parking bay.

Opening the rear cargo door would every time smack into the garage door ( I have physically prevented otherwise damaging contact) due to the swing clearance, perhaps the angle of the sensor is not designed for this ultrasonic sensor, or my sensor is not adjusted correctly.

I don't believe there is a rear cargo hatch sensor. other than the backup camera.
