Took our 2014 GDI to France last year and in 2500 miles we had no problems at all, as you would expect for a new car. Other than the standard stuff you would take in any car going to France I have two recommendations.
1. The windscreen wipers work great in the rain but are useless at clearing flies/road muck off. Take a wet sponge or cloth in a plastic bag so when you are a couple of hundred miles from the cottage you can clean the screen sufficiently to see to get back.
2. The ground clearance under the gearbox mount is not good and will ground going over the horrific speed humps you will come across in some of the smaller villages, particularly when two up and full of luggage. Take it easy and you will be fine.
Have a great holiday.
