There are a host of things that can cause the symptom you describe (the only thing we have to go on at this point). Your mechanic might be giving you good info, or maybe not - there's no way to tell from what you typed above.

The prudent thing to do would be to hook up a scanner and see what codes the car are present, which should narrow down the issue dramatically. Ideally, if you could find a Honda-specific bidirectional scan tool, you'd get more specific information, but barring that even a generic reader will move you light years ahead of where you are now.

Give us the info on the codes, and we may (or may not) be able to help.

That's a lot of very specific / seemingly somewhat unrelated systems to be showing codes. I do see that there is a voltage-related failure, which would make me wonder if some (if not all) the other codes could have been triggered by a low-voltage event (like a low battery / bad alternator, etc.). When I have a lot of seemingly random failure codes, I will usually record them, then reset them all and see which ones (if any) come back.

There are procedures for clearing VSA / ABS errors - I'm guessing there should be some mention of it on this forum (or on similar forums). I don't have access to my factory service manual, but search on that and you should be able to find a free and easy download... the FSM is your best friend when you're chasing an issue like this one. I'd try that - hopefully the process for the 1G MDX doesn't require a laptop running HDS (Honda Diagnostic System) but only shorting pins in the OBD connector (daunting for some, but not that difficult).

FWIW, used ABS modules are dirt cheap on eBay (and no doubt elsewhere). I don't think they require programming to work, but you'd want to research that. That's not to say that just everyone can swap an ABS module (with or without programming) but it's certainly worth looking into.

I think you'd benefit checking out this thread on the same subject...
