Mine have not stuck closed - but they seem to bounce off the door seals unless you really slam the doors hard. IF I decide to buy a 2014 in the months ahead I will DEFINITELY add the soft close door option - NOW I know why!
Until then, I just tell my passengers to slam the doors and pretend that they are getting into a $70,000 Kia.
My opinions are free - you'll get exactly what you pay for!
