 All though I have enjoyed my hyundai very much, in the winter it is very cold. I can't leave my car running to warm up without staying in it.  There is a saftey feature that won't allow you to lock your doors with the car running so that you won't lock your self out.  This may be good for people in warm places but for me it is very frustrating.  When I asked my local dealer about it they weren't much help at all.  Also for "SAFTEY REASONS" you should be able to lock yourself in in case an extreme situation forces you to do so.
