Received this little love note in the mail today from Nissan.
I assume this does NOT apply to all model years, but Nissan IS acknowledging the fact that there are some faulty master cylinders out there. Though they are not calling it an all out recall, they will replace the master cylinder at no charge to you should you show symptoms. If you already paid for the repair out of warranty, they will reimburse you. Good to know, especially if you are now second owner of your Altima (noobs!). I for one had mine replaced under warranty about 2.5 years ago. Symptoms is just like it says, brake light on with no brake engaged.
PS to Mods: Im not sure if this is Altima Coupe specific or not. The letter only states "Altima". It might be a good idea to ghost this thread into Altima Gen Chat as well.
