Tesla active hood deployed after driving over raised manhole cover...

[DavidR1]

I drove over a raised manhole cover a couple of weeks ago (unmarked etc) and the car bottomed out causing the plastic shield to come off (see photo of the manhole cover and part). Surprisingly the active hood was deployed without any front or side collision at all.

Tesla contends that "the car behaved as expected". I really don't understand how that could possibly be the case. Thoughts?

What's "active hood". Do you mean "bonnet" and whats your definition of "active", in this particular case?

Tesla's "Active Hood" Safety Feature Could Save Lives

Tesla's little-known "Active Hood" feature could save pedestrians from severe head trauma, which commonly results in fatality.

What the heck is an "active hood"??

 

[KyleDay]

If you bottomed out and ripped off the bottom cover, that may have been enough force to depress the “escape” button inside the hood that is intended for kids to be able to escape.

Active hood - if I understand it correctly - is where the hood will pop upward in hopes of causing a human less harm. Think of it as a soft platform for pedestrians to fall on. I think Nissan GT-Rs had an issue with this a few years back. Normally it fires one time use struts close the windshield anchor points.

Kind of like this article shows:

Nissan to offer pop up hood safety feature on new Skyline

Nissan will offer a new safety feature when its new Skyline coupe hits showrooms later this year in Japan.

That is what comes to my mind anyways - I could be completely off.

I don't think US cars have this feature, but I could be wrong.

Anyway, I'm not sure how OP is squaring up smashing into a raised manhole cover with enough force to rip parts off the bottom of the car, and "... the active hood was deployed without any front or side collision at all."

Uhh, seems you most certainly collided with something.

No this was definitely the active hood that opens a completely different way with a different mechanism

100% definitely no collision with *anything*

I did not know that this feature exists in MS and MX. ( not very anxious to find out )

Very interesting...sounds like a shitty situation to be in, and I think a lot of us learned something new about their cars in the process. Thanks?

Clearly the car detected some force which their was (you hit something after all) and deployed the "active hood" whatever the hell it is. Apparently force doesn't have to be to the face of the vehicle for this to happen. Did the vehicle lift in the front and come back down with some impact? I mean it kind of must have, right?

As I mentioned, it sounds like this is a euro-only feature. There's no mention of it in the US-spec owners manual.

This is either a collision or a comprehensive claim.

a hood that had too much sugar before bedtime.

It’s basically a double mechanism on the hinge part that support reverse movement if an impact to specific areas. I can’t take a photo of my car now but here is an article about it:

It's even mentioned at the first entry of Glossary | Euro NCAP.

 

[rooter]

It's mandated in the EU and maybe other countries. No US car has it.

You mean other than the raised manhole cover you plowed into and “bottomed out” on, right?
