Same issue with it for me too - husband had a Megane and battery used to go flat if we didn’t drive it for a few weeks (holidays etc). Apparently electrics is a common fault with Renault - i was told this.I had one in the late nineties so things have changed a bit since, but it was ok. Reliable. The only real issues I have had with it were electrical gremlins that seemed to plague that particular model.
it was quite the step up from the 1970 morris minor I’d driven for years before it though so I might have been easily impressed![]()
after having car issues last month I would recommend a breakdown service provision for sure. One of those ones you grumble about paying it but when you need it and don’t have it then it’s a mare!!!!
