Car makers are almost as bad.
The rubber radio volume knob on my 2017 Ford Focus has started breaking down. Officially it is available as a spare but only with the facia for £152!
I've tried to pull it off unsuccessfully but before I use mechanical assistance to get off (which will mangle it to an unsightly mess) I emailed Ford to ask if it is pull off [1] they just referred me back to a dealer, who've said they don't know. Knobs that look like they fit are only £4 on ebay (No 'Vol' text on it but I could live without it)
Yes there is volume up/down paddles on the steering wheel but I know my wife will have the heebie jeebies as a passenger or occasional driver as she won't be using the paddles.
[1] Google/youtube searches are flooded with irrelevant answers. I've lost my google mojo.
