I had a Lexus ES350 that had a melting dash, and the recall for it has ended a year prior to me having the issue. Essentially the dash was engineered to be easier to recycle/break down - but inadvertently had a lifetime limitation to it. The rest of the car was in decent enough shape and didn’t give me any real problems. There were alternate solutions to fixing the dash, but once you start talking 200000 miles on a chassis - you’re gonna start replacing things. Touched surfaces start breaking down; things with less robust parts (cd player) start having issues etc. Overall the entire package just starts looking tired, and replacing the whole thing looks more attractive than trying to find parts for a fifteen year old car. Perhaps modularization in the future can help. For instance I wouldn’t have minded replacing the audio system in the car - but it was very much a specialized installation that wasn’t a standardized “double din” setup. Also trying to find basic comforts like replacement seat cushions or leather to match gets tricky after the manufacturer stops keeping stock.
