Hello everyone,
Last year, I bought a brand new 2022 Honda Odyssey EX. Currently it has 24000 miles. At about 500 miles when I was climbing this hill, the car began making a kind of a rattling noise like a metal wire rattling around inside a steel spraycan. It has been making that sound ever since and it hasn't gone away. It always seems to make it at about 1800 rpm at various speeds and always when the acceleration pedal is pushed and maintained at about those RPMs.
I took the minivan to two different dealerships. One couldn't replicate the issue, while the other was able to replicate it, but couldn't give me an answer as to what it is. They said they have to take apart the whole dashboard because they thought it is coming from underneath there somewhere. They also said that de-constructing the dashboard and re-assembling it can cause all kinds of other noises later, so I declined their offer to investigate this issue further.
Could this be coming from the transmission or the engine? It's really a bummer that this noise is still present. It makes the car sound like junky. It doesn't appear to affect performance though.

Please check the FAQ
almost for certain this is from the VCM( Variable Cylinder Management)actuating, the car goes from 6 to 3 cylinders around these rpm's.
I had a 2018 odyssey when I first became aware of the issue, now have a 2021 same thing. not so much a noise but vibrations in the steering and chassis when the car is running on 3 cylinders that the special engine mounts are supposed to eliminate but DONT!
have have installed on my current 21 and previous 18 the S-VCM Controller that takes about 15 minutes to install and keeps the car from going into 3 cyl mode, maybe lost 1/2 mpg and car runs smooth ALWAYS
also the VCM is known to cause wear on the engine and the expensive to replace engine mounts so look into this or one of the similar products on the market
I would not have purchased any Honda again if i had to live with the VCM and its flaws
Good luck hope this helps
FYI Honda is well aware of the problems and will NEVER admit to it
