Sunroof rattles, after three visits to my dealer trying to get it fixed I gave up.
Two major electrical faults which were very expensive to fix.
Remote door opening buttons on keys stopped working after 18 months.
Driver door restriction mechanism broke after 18 months.
Good engine, excellent handling.
Poor overall build quality and soft/uncomfortable seats let this car down.
I had a 306 Spinnaker and I had major problems too.
The main problem was the central locking, the button in the key stopped working, and then you would go along and then the doors would all of a sudden lock you in.
Also if you were getting something from the boot the doors would lock and unlock themselves continuously until you shut the tailgate.
Another problem is the reversing lights never worked and the wiring has been checked several times by a dealer.
Another niggle is the drivers brake light stays illuminated when the tail lights are on.
I found it to be a nightmare, but overall satisfactory.
