If the car is still under warranty then why not complain?
I noticed on the dealer paperwork a note that seemed to be the cost of the track rod end, I think it was around £50 I only got a quick peek though! Anyway the track rod was replaced as were both front tyres, the tracking was checked and all for £0.00. All for the price of one email and two phone calls.
Check the inside edge of your front tyres and walls to see if they are worn, if so then it's up to you whether you put up with it or get if fixed, in my opinion it's a no brainer.
After the run over the bumps yesterday there was perhaps a very slight creak but my wife could not be certain if it was the suspension or my old bones creaking, then again it could be us being paranoid and hearing something that was not there. Time will tell.......
