I noticed the same thing after a cold snap in Colorado. I took it in and after it cooled down they heard the noise for a second. The dealer ordered a new belt tensioner and a new belt, I'm awaiting the call that the part came in. I will post when the repair is completed and if it fixed the problem.
I have the same sound for a second on 1st start up in cold weather too.
I get the same sound from Chev Express work van too, also the same with my previous vehicle which was a Chev Astro.
sounds like a normal thing to me ....I think
But I have a problem when my Honda sounds like a Chevy I'll mention it to the dealer next time I am in.
I definitely have the noise...kind of a grinding-of-the-gears sound. At first I thought it might have me holding the key too long in the start position. But now after testing I'm convinced the sound definitely isn't caused by anything I'm doing during the start process.
I definitely don't like grinding sounds during the first month. I'll be watching this thread and talking to the dealer soon.
Thanks to all who post here - as a one month new owner I continue to be amazed at all the valuable info that is posted and available.
I noticed this sound on mine as well and seen this thread. Just wondering if anyone got an answer from honda as to what it is. Doesn't sound healthy to me. It makes that sound as though you were to turn the ignition and hold it after it's started. As with everyone else, it's only during a cold start and only for a second.
I'll be taking my truck in this week to fix a leak. I'll try to remember to ask about it then.
This post is by no means official, but i heard the noise the last couple of mornings. it has been below 20 in the mornings here. The noise is the same noise i used to get with my 03 F250. it was the power steering pump. Except on the ford, it used to last for close to a minute, or until i moved the steering wheel.
I think it may have something to do with the type of power steering fluid that is now in use. in the 3 years i owned the ford, it never got worse or better. it was something i got used to.
we have it up here also. fortunately it happens in many other makes and models. that i have driven. i guess the cold here in canada is more common. i have had it in a jeep,chevy venture, and astro for sure oh and yes the ridge. has to be cold to here it. sounds like a blader(gas pump) when it is priming for the first time in the cold. never asked a mech or had anything done to my other trucks. hope this helps
