Within days of delivery, the arm-rest hinged between the front seats, gave way when leaned on. The manufacturers 'tightened' it, but it continued to give way. I have mentioned it at every service, but the consensus from the Service dept. is,
"Arm rests are not really for leaning on". I now keep it permanently up.
After 15,000 miles, the ignition/electrics failed causing engine to sound and move like a tractor at 10 mph. This was easily mended by fitting a new coil at cost of about £250 - and then it happened again at a later date.
At 20,000 miles, occasional scraping sounds from undercarriage worried me, but as no warning light appeared on dash board - I ignored it until convenient to drop in at Renault Service later in the month. It turned out to be very dangerously worn break shoes - (I wasn't even allowed to drive away) and Renault Service explained that the warning light only shows up (in the case of break shoes) in one corner - mine were in the other.
Key handle/fob comes away from metal "key stick". On the first occasion this happened I thought I had lost it, hunted everywhere, only to find it still firmly lodged in the ignition! I stuck it back with super glue but it came away again later.
Tailgate needs very firm 'wham' to shut tight - so anyone helping to unload has to be warned of this (or you might drive away with hatch dangerously loose and waste the interior lighting/battery).
