highly likely that this is because i doubt CA or NV are classified as "cold weather states". They are only issuing recalls for certain states, more than likely they are all the northernmost states or those that are not coastal where the ocean can help to keep the areas somewhat warmer. i would suggest you dont worry about fixing it just yet because i was told that a warranty on the fuel system or something was going to be issued on these cars in the next few weeks. if it is so bad you cannot wait then by all means fix it otherwise you might be able to save urself a pretty penny :P
