What did you expect with a Renault?
I had always thought they were a good make but it seems loads of people have trouble with the electrics on them. I have replaced 2 lots of drivers door central locking and 2 tailgate locks plus drivers side electric window motor and switches. The drivers side electric window is still playing up, if you open it and then go to close it it goes down not up and then wont close again. I picked my wife up from Heathrow and after opening the window to put the ticket in the machine to open the barrier it stayed down and I drove all the way back to Southampton on a freezing cold day with it wide open!!
I think its time to get something else!!
All this with a car that has only done 49,000 miles!
My 2wd Sapphire that I have had for 21 years has had fewer problems with its so called outdated technology!
