I have two gripes, one is rather insignificant and the other is really annoying.
1) I have a car seat, and the vehicle constantly is telling me that the seat belt isn't done up even though the seat is empty. The weight sensor must be very sensitive. It's annoying to have the screen show an error basically all the time. I suppose a workaround would be to buckle it up even when not in use but that's pretty annoying too.
2) Sunscreen is a disaster on the seats. I tried using an armour all leather wipe to clean it off and that was a huge mistake- it gave a shiny gloss to the areas I used it on, now they don't match the rest of the seats. Baby wipes work pretty well for getting the suncreen off but it's summertime and I have a 6 year old.. I don't want to be one of those jerks that lays down towels when I have people in the car but I've never seen a car more prone to staining than this one.
