If it were me I would sell the old lens on ebay as not working and use that money to fund the new 18-135 STM. The old lens is uneconomical to send to Canon for repair. You might find a third party to do the repair but a new lens gets you better optics and another year of warranty for not a lot more money than a repair.

Just my opinion.

Agree.

If you want to DIY, my guess at the symptoms is a bad ribbon cable inside the lens.  They fold/unfold as the lens is zoomed and may have developed a short that misreports the focal length and aperture.  You may (or may not) be able to find replacement cables and do your own replacement.  A third-party repair outfit may be able to diagnose/fix it for <$200, but if it's more I'd do as OhioBob susgests and sell it as is as a "parts mule" for someone and shop for a new lens.

IMHO, YMMV
