Why didn't you take it back immediately?

Because they assured me it was normal for those cars. And that they would put it right if it turned out they were wrong. I gave them the benefit of the doubt, not having driven that exact model before. It was quite subtle vibration at the time (now much worse).

Reject it OP. It's clearly not fit for purpose so get your money back.

If you don't get rid now though, at least make sure you do so within six years.

just the 6 years....
