Liftgate (rear trunk) trying to eat my mother-in-law

[jomo25]

But that is on opening, with the car thinking that the liftgate opening was blocked, yes?

That's different than the OP's case, I'd imagine, where presumably it's been sitting open for a while and just decides to close on its own.

That's the bug. The lift gate 'thinks' it is blocked so it begins to close. But in fact it wasn't blocked. (And mine was on level ground). The issue is the trunk hits the max, thinks its blocked and starts to shut on it s own, while beeping. That's why resetting the open point slightly lower than the max eliminates the issues. It doesn't 'bump' against the physical max and close.

I can't say for certain the OP was having this same issue. Bt it is the one I had. And others had. Which is why the support team knew of and advised this workaround til I next come in for other service.

Then press/hold the trunk close button on the trunk to set memory for that location.

Are you sure it remembers per location? I don't seem to recall this being true for my car, but I'll have to test it.

I'm posting this in case anyone can help me understand why my Model S seems to want to eat my mother-in-law.

I don't see this as a problem, unless you are upset that it didn't succeed.

Seriously, after one of my firmware updates my rear hatch did the same thing. opened then immediately closed. resetting the opening height worked.

I'm pretty sure he meant "for that location of the trunk hatch" not location of the car.

I'm pretty sure he meant "for that location of the trunk hatch" not location of the car.

Oh. I guess I read it wrong. It didn't even occur to me that he could've meant hatch position/height.

Although if possible... Remembering the height per (vehicle) location would be awesomely useful.

Thanks for the tips, everyone.

I'll try resetting the max height and see if that "fixes" it, but I still haven't actually witnessed this behavior for myself.

My wife and I left the kiddos with her mother last night and took the Model S out for dinner and a movie. She drove on the way to dinner, and tried to recreate the issue but couldn't (much to her frustration).

Also, they were on flat, level ground each time the issue occurred.

More as I know it myself.

There is another thread on this. If the hatch is left open over night you need to manually close it to reset it.

OK, didn't know that. Apparently I've never before left the hatch open overnight in the 10+ months I've had the car.

I'm having this issue and would like to try resetting the stop point of the hatch opening, but don't know how to get it to stop. It's either on its way up or its on its way down. How do I either open it manually or otherwise get it to stop so I can reset the stop point?
Thanks!

Quick Update:

As of today (Saturday, Sept. 21) neither my wife nor I have been unable to replicate this issue. I've had my first Ranger service since then as well and they were unable to find anything unusual either. So the mystery continues, and I'll update later if we ever see it happen again.

PS - In what is either an example of the most amazing, most proactive customer service I've ever encountered in my life or an intrusively creepy, Big Brother-esque display of disappearing privacy (I'm choosing the former, although YMMV), Tesla actually reached out to me after I posted this thread. They called and left a message saying they'd seen on the boards that I was having an issue with a car that had, in their words, "developed a taste for mothers-in-law" and wanted to see if everything was okay and what they could do to help. I laughed my butt off when I got the voicemail - these guys are serious about making sure their customers are happy!

So, hi everyone from Tesla who's reading these boards! Thanks for the great car and service! ;-)

Open the hatch and when it stops, move the hatch to the opening spot you want. The press and hold the open button on the hatch lid until you hear a few beeps.

You can always stop the hatch by holding it while it's moving and the move it to the desired position..

Thanks. Mine never stopped. (just went all the way up and then immediately all the way down) But I was able to press and hold the close button when it was almost to the top. That reset the stop point and fixed my problem.

 

[ken830]

After it opens all the way, just pull it down partially.

He was saying that it would automatically begin to go down when it reached the top. So, it never stopped while open. Sounds like he got it set by just setting it while it was in motion.

Stop putting your mother-in-law in the rear trunk.

Put her in the frunk instead.

Has Tesla ever explain this problem or even tried to remedy it?

 

[lhoffjr1937]

Tesla service could not dublicate the problem. But when I arrived home in my driveway it continues every time. If it is the slope as one blogger suggested then Tesla should issue a statement. Tesla's silence is disturbing!

All I had to do was reset the opening height for the rear hatch. it has not occurred since.
