 My all wheel drive lights keeps  coming on. The handbook says do not drive but take car for service. We did four times. Our local dealer will not fix it. Hundai headquarters keeps lying to us. Does not call, tells us they have written to us on Oct. 18. Letter never arrived. Now we have filed the Lemon Law.  This is my second Hundai but I will never buy another one if they do not fix this. Now I do not know if my all wheel drive will protect me when winter comes again. I had  been in Arizona the last winters, so don't really know if this is a serious problem or not but why would the handbook say it is a problem? Hundai will not help you! Be forewarned.
