I have complained about the fan on numerous occasions and the dealership tells me it's absolutely normal. It is unbearably loud now that it is cold out and I am very annoyed by this because even my car-dumb friends notice how loud it is. I don't know what else to do. I know if I call American Honda to complain, they'll tell me "Has the dealer replicated it?". When I say "no", they'll say "then theres nothing we can do to help you."
This was the same nightmare I went through with 3rd gear in my 2006 Si.
I had this issue (much less intensely) on my 2010 EX-L. One dealer said it was normal, the other heard it and replaced the blower motor and it was fine for awhile, but it came back. They won't touch it on my 2012 Si despite my complaints. I did see my service writer put down "blower motor bulletin" on a piece of paper. Unfortunately, I lost access to the Honda Service News Bulletins to see if this has been addressed on there, so I'm feeling very hopeless here. (and yes, for those 8thCivic members who saw the
Service Bulletin Archive (take a look), that was me that did it. Let's see how many of you remember me

).
I also have the seat back popping issue. On my first 2012, they caught it - said they'd try to insulate "it" so it wouldn't do it anymore, otherwise they'd have to replace the frame. Car was totaled (not my fault) before they would replace the seat frame. My replacement Si is starting to do it too, but I'm just going to wait for it to sound like a roll of bubble wrap before wasting my time.
I think I'm just going to make a T-Shirt with "We were unable to replicate your concern" on the front of it and wear it every time I go to the dealership.
Keep us posted about the issues OP. If necessary, I am willing to start a thread devoted to sharing case file numbers from American Honda Customer Service about the noisy fan - who you spoke to, what was said, etc. I did this on 8thCivic for third gear before the TSB came out and it was pretty helpful. When Honda told us "We've never heard that before.", we were able to say "actually, I have 30 case file numbers right here that are complaining about the same exact thing. Would you like to check any of them or are you going to tell me you've never heard of it again?" When I had her check one of them "That case file doesn't exist."
See HERE for Example.
I bet it doesn't Honda, I bet it doesn't.
Thoughts? It might be helpful. We can all call in and complain about the noisy fan (and I KNOW we're not the only users on here that have it), and report our results and information using a predetermined layout I can put together (similar to what I did on the case file numbers).
