I mean that sounds more like "It's a pain in the ass to change a headlight in my girlfriend's car, so I have her bring it to a shop" than a right to repair issue. Or are you saying the shop needs special tooling to get the job done? What kind of car is it? There's usually a few YouTube videos showing how to do things like this.

I have an older gas guzzling SUV on a truck chassis. Lots of repairs are a lot easier than my wife's car, because there is a lot more space. But that is a fundamental tradeoff between two vehicle classes and gas guzzlers versus high MPG crossovers. My SUV is newer than her car too.
