Hi 
  
The Nissan garage carried out a repair to the soft top just over a week ago ( well they subcontracted it to a specialist ). 
It was going a bit at the seems and the bottom corners where it meets the back of the doors. 
This seems to have involved them stretching the fabric a bit. 
This was done under warranty. 
Now I find that when I first open the roof, it often gets stuck just at its last phase, and I have to close and open it again, then it tends to go in with a thud. 
This never happened before ( although I have only owned the car for just 5 weeks ). 
The Nissan garage says its probably because of the temperature being low, but as you know, its been mild so far this winter, and I live in Bournemouth near the sea. 
I wonder whether the repairers have over stretched the fabric, putting pressure on the mechanism. 
Am I being fogged off!?
