Gen 4 internal rattle

The sensor box is the cover over the camera and other sensors just behind the rear view mirror.

James, Martin, you might be right, my cover was slightly loose and the noise is definately right for a piece of loose plastic.

Of course it won't do it this morning, but I suspect the engine/interior has to get up to temperature before it does rattle and it's fairly cold here.

I stuffed a couple of pieces of soft foam between the edge and the roof lining, it doesn't move now so we will see if that stops the rattle.

Soley, I did check the glove box as the rattle did appear to be coming from that direction, only slighter higher up. However, even with everything that can rattle removed and a co-pilot holding the glove box open it still rattled so don't think it was coming from there.


I get a bit of a strange noise/vibration from the engine bay at around 1,700rpm, it is worse when that range has been used for a while, E.g. off-road, especially in 4WD-L as I use 1,500 to 2,200 rpm a fair bit.

I am not sure if this is anything to worry about or if it sets the internal trim off rattling?

Check the heat shields on the exhaust, especially those around the catalytic converter, cracked welds can allow them to vibrate in specific rpm ranges, just bending them slightly will often silence them.

Thanks Fordem, it does sound a bit like a heat shield and only does it when going slow, so heat may be building up in there.

I will have a look tomorrow.

Ok thanks. Wondered if it was referring to something behind the dash, it sounds more like the speedo binnacle or behind it or the round vent by the drivers door.

I took my Jimny for an hours drive today and tried my best to hit the vibration speed, but no noise whatsoever, so it looks like it was the sensor box cover and the bits of foam jammed in the sides has done the trick.

There was no noise from under the bonnet either, but I still have the heat shield to check.

When the heatshield comes lose the rattle is so loud that people actually turn round in the street to point and laugh at you, so I wouldn't bother crawling underneath in the wet looking, wait until it is dry (May-June maybe?) if you must check it
