Thumping noise from boot area

[chrisphet]

Hi, can anyone help me with my is300h 2020 . When I go over bumps I'm getting a thumping noise from the boot . I've tightened down the Battery,  removed the framework where the tyre gunk goes, even removed my jack . The boot lid wasn't fitting properly so I've extended the rubber mounts and that fits nice and snug now .  I've even stuck down the rear folding seats but I'm still getting the thumping sound . If anyone has any ideas I'd be really grateful.  Cheers Chris

Have you eliminated the possibility that it might be related to the rear suspension?  Does it appear to originate from the centre of the rear or favour one side?

Strange the boot needs adjusting on a 2020 car. Has the car been rear ended? Have you checked the exhaust?

[chrisphet]

It seems to favour more to the right side . I've given the rear on both sides a good heavy push down and it bounces straight back with no bounce. It's very frustrating as it really spoils the drive and dread hitting heavy bumps . Is there another way of testing the rear suspension?

as far as I know it's a straight car , can't see any evidence of a rear end bump . Yeah I gave the exhaust a good waggle and it seems very secure

Are any of your children missing?They might be locked in the boot.

I suspect a mechanic might put it on a hoist and then jack up the chassis so that the suspension is no longer loaded. - which might reveal any source of movement or wear.

I locked them in my last car and sold it

Next time I'm off work I'll pop round to my mechanic and let him look . Thanks

Have you checked the tool tray in the boot? I would still lean towards suspension however. Keep us posted

You need a garage that has a ramp with “shuffle plates” the car is driven on and the plates shake the car while all the suspension components are checked for play.

In your case the noise in the boot should also show up.
