I don't think this is true. Lot's of folks on a forum like this would pick it. But the social norms around repair have degraded significantly (in large part no doubt, to it not being a cost-effective option). But my main point is that it will take more than just availability. And thus there is no market pressure, so it doesn't appear to me that this is indeed a market failure, instead it looks like the market responding to the demand.

Let me illustrate further, if a top provider of electronics and appliances, but not fully market dominate in many niches, say LG, pledged and followed through on their pledge to ensure the repairability of their products, and remained price-competitive, would they gain significant market share over their competitors? In phones? In appliances sold at a big box store? Or would people choosing an Apple device, or GE Fridge still choose those options because of features and market clout and ignore the repairability? I predict they'd gain some marginal sales, but really wouldn't incentivize change amongst their competition.

Now there are markets where the dynamic is different. Farming equipment, where there are some strong challengers to Deere and one of the things they sometimes use to different is repairability. There the market failure I'd be concerned with is the vertical alignment of dealers with service.
