Knocking noise from rear suspension

[Neil Fellows]

Sorry if this isn't a great explanation, but just noticed a loud 'knock' coming from the rear of the car when going over potholes, speed bumps etc. Never done it before. Not sure it would be picked up on a recording if I did one, so trying to explain here instead!

It's almost like heaving a heavy concrete block in the boot and zooming over a pothole. My boot is empty, usual loading covers in place, spare wheel kit bolted down fine.

Has anyone else experienced this please? Its a 2021 MG5 SR, 10,000 miles.

Boot lid fully shut? (Though I expect there is a display telling you if not)

I will double check!

Could also be something rattling around in the boot.

Mechanical knocking / popping noise coming from rear of MG5 Long Range

Hi All I'm new to the forum but have read loads on it over the past 6 months or so whilst deciding whether I should buy an MG5 Long Range or not. .... Well, I took the plunge and bought one in Piccadilly Blue and I have to say I love it. I've had it for about 2 months so far.... But...

Some other owners have had this problem. Turned out to be rear shock absorbers.

Saw a couple of reports the other day of fractured springs! That symptom is absolutely textbook for that problem and the can be surprisingly difficult to spot if the fracture is only an inch or two from the end.
