Suspension broken?

Earlier this week I was in Cornwall and had to take the car over some pretty rough roads.

When I was driving back on Wednesday night I slowed from 70 mph for a junction when I heard a bang (like something hit the underside of the car, followed by metallic rattling for a second or so).

The car sat right down on its suspension on both sides.

I'm puzzled as to what could break to cause both sides to drop.

I don't really know but do I remember that the roadster shocks are fed by an external gas reservoir or was that some kind of aftermarket thing? Could it be both rear shocks are fed by the same source? e2a: and therefore if one point of failure occurred both sides would droop?

Otherwise, dunno, I thought my knowledge of suspension/car components was decent but can't think off the top of my head what would cause both sides to drop like that, apart from one side breaking causing the other side to break also due to the shock/strain but I can't imagine that... :-(

So I picked the car up this morning.

Tesla said there was nothing fundamentally wrong with it. They checked all the joints and road tested it a couple of times.

Driving it back, it seemed to me things were a lot more taught and predictable - i.e. like normal. The splitter is at normal height and it seems the camber angle on the rear wheels is less severe. I'm thinking they may have just tweaked some stuff.

They also thoroughly cleaned the car inside and out, even the PEM looks clean.

Total cost was £0.00 so I certainly can't complain about that :)


Here's the offending bolt (apologies but the TMC server has turned the pic upside down)

That's a nasty bolt.

I had a wishbone replaced once because its tolerance was getting a bit too much, so was very interested in what had happened to your RS.

Fortunately its just this AND it didn't hit anything vital :)

- edit -

I'm confused...is that bolt from somewhere on the car, or is that some road debris that got picked up and thrown into the underside of the car?

With the SC having done a really close inspection, I presume its not from the roadster.

Glad to hear that Tesla did not find anything wrong with your Roadster. It appears that bolt penetrated a non-essential part of the car. Based on the photo (which appears right side up in Tapatalk on my iPad) I don't see how it could cause a problem with the suspension or anything else. Am o missing something here?
