weird noises

Hi everyone! I own a 2007 Accord EX-L 3.0 and I'm hearing a weird knocking noise only on reverse. Breaking doesn't matter to the sound. Plus the car tends to vibrate sometimes. Here's a link for a video so you guys can get a better idea. New video by Patrick .C Thank you for taking the time!

What should I do about my 2012 2.4l 4cyl accord coupe grinding when I start it up after a while ( cold start ) ?

Here recently I have been hearing some weird noise from my car. A 2011 accord coupe ex-l l4. It only happens when the engine is cold and I start it. Other then the annoying noise it makes for a few seconds the only other symptom I have is that my mpg has decreased by 50 miles. Does anyone else...

i spoke to my dad (who i'd say is pretty knowledgable with cars) and he suspects that its the water pump. its been going on for a couple of weeks now. i figured it was something minor that would go away at first, but..... it hasn't! LOL. –*from the inside of the car, it sounds a lot like a lot...
