Not in the US. First of all, most people only go to a dealer when something goes wrong. Routine maintenance is far cheaper at non-dealer service shops. If there is a manufacturer's technical bulletin on an item (such as a computer update) and you take the car in for any service, they will do the recommended update to programming. But there is no mandatory notification of owners. There are also technical service bulletins on mechanical items that are only done if you are having service done on the involved part. And you generally pay for that TSB being done. Not always, but some you do pay for.
Recalls, yes, if you get a notice of a recall, you make an appointment with a dealer (for your make car) and they will do that for free. Any other work you have done you will be charged for that other work.
If you are one of those folks who look at services to be done every xxx miles/km and take it to your dealer for the xxx checkup, the dealer MAY also do programming updates. Again, not a lot of folks do that over here.
Meaning it's hit or miss on getting updates to programming done.
