Ever since I bought my 8, I've noticed that theres a little vibration under the driver seat, but lately it has been more noticeable. Now when I'm at idle, I can feel it more and more... Anyone know what this is, or is it normal?

 

This car just does not idle smooth, which is strange because it runs so smooth at any other time besides idle. If it is abnormal vibration, it could be bad motor mount(s). There have been some members that have had them replaced under warranty. Some searching and reading on idle & vibration should give you plenty of additional info.

 

Oh no I already know that, I had my motor and engine mounts replaced under warranty due to wear and tear... but it just seems like its still a little abnormal! Highly doubt that the motor/engine mounts have to be replaced again.....i have no clue

 

Yup its them dam motor mounts
