Hyundai i20 Rattling Sound When Passenger Window Closed

[potblack2win]

i Guys,

A couple of months ago I purchased a i20 N Line (2021) model with only 400 miles on clock.

I have noticed a annoying rattling / squeaking sound when going over uneven bumps from the left side front passenger door side.

This only seems to occur when the window is fully closed shut, but if I open the window between 1-2 inches the noise is gone?
What could be this problem?

Take it to the supplying dealer & let them work it out, the actual cause is not relevant if you are just getting it fixed under warranty.

Will try to get it booked in.

Hopefully they don't just say we cant hear it.

Yes, get it done under warranty. Potentially it is the window lift mechanism, which will need fixing befor it fails and the window drops - bad news when it’s raining! It sounds like a single item is loose or failed, that is, a clip, nylon bush, etc., in the (presumably scissor lift) mechanism.
