Slight beeping sound while driving
 

Hey all,

I have noticed just today (almost at 30k miles) that when my car hits small bumps in the back that my horn kinda goes off. It's very barely noticeable but I am scared one day it'll just go ballistic. I just had the car checked up last week and they did an ECU flash for the idling issues. I know there are two ECU's and this is likely not due to the engine ECU, but do you guys know what the problem can be? I drive an automatic FR-S and have only had issues with the rear headlight fogging up and windows rolling down in the winter. :thanks:

I might be missing something, but that issue is related to the clutch and OP says he has an automatic.
