The reason for one year is because there are usually issues in the car.
In my case:
First the whole dashoard had to be taken out and reinstated as there was a wiring loose, as i had not touched the panel so it was covered in warranty.
twice i have had my horns replaced, this time around the wore has broken from the grip, i have to take it to the dealership for replacement and getting it fixed
So yes let the vehicle run for a few days and get confidence and fix the messup made by assemblers before giving them an easy excuse.
