Does anyone else think Renault Laguna's are crap?

I have 5 yr old Laguna and so far, neither of the keys lock the doors and if I lock the doors manually the keys then don't open them, the remote radio keys don't work, the driver door window doesn't go back up once it's down uless I manually force it and now I've been told I have rusty break disks - on a 5 yr old car! Is this normal behaviour for a renault?
