Hey everybody. Just traded in my 2023 RDX A-spec Advance for a 2025 MDX type S and I am loving it except for one thing. I can't do any system updates. Every time I try it I get error message "Update is Unavailable/ Code S404" and a try again later message. Any suggestions on what may be the issue or what else I should try?

Thanks!

 

Just going out on a limb here, but maybe no update is available?

 

Totally possible, but seems like its been out long enough to have caught at least one update. I can't find any documentation anywhere that tells me either way. Oh well. Will wait and see.

 

I'd suggest adding it to a list to ask your dealer at next oilchange.

Alternatively, post your software version mumber and steps that cause the message. Other 25 owners might be able to see if they see the same.

 

I get the same error message too. Were you able to get yours fixed. I am the Acura dealership now having them look at it
