Rattle over bumps

[mobar]

When I go over bumps around my home I am getting a rattle from underneath the car, it also happens sometimes when I take my foot off the accelerator. I am curious if anyone has any idea what this is or if anyone has had this problem before. I have taken it into the technicians twice and they cannot replicate it or find any sort of problem. I will attach some videos for reference.
Thanks in advance!

Hi,

I recently purchased a new 1L 110 Kamiq and I'm experiencing the same rattle sound underneath the car. It happens both when going over bumps and when I let off the accelerator. Have you found any solutions for this issue? Any insights would be greatly appreciated!

Thank you in advance,

I had an odd rattle and it turned out to be a small stone trapped behind the front brake caliper shield.mine was more noticeable on bumps when turning left but worth a look.
