We have a 2004 Honda Civic that makes a roaring noise the faster the car goes - doesn't affect the performance of the car.

SOURCE: roaring noise front end

it sounds like a bad hub bearing

try raising the front end off of the ground and spin the tires by hand and feel for roughness in the hubs

SOURCE: My 2002 honda civic has a steady clicking noise

sounds like rockers need adjustment or timing belt or even the timing belt has split and frayed causing a slapping noise on the engine components as upon acceleration will cause such a noise happened to me a few times before as well ..open hood and visually inspect ....then start engine if nothing is seen and locate the source of noise this way just keep your hands etc away from moving parts

Could be the squeler on the brakes. Does that to let you know it's time for brake job. Have your brakes checked

This may sound really dumb but have you tried shutting the alarm off with the remote before turning the key? I am sorta wondering if your key is worn out and the alarm system reads it like someone putting a screw driver in there to unlock it. Just a thought. I am guessing here so please be gentle on me.

I know this original question was written quite a few months back but I was wondering if you ever found out what the high pitch sound was. I just purchased a used 2005 Honda Odyssey and it is doing the exact same thing. Any advice?
