Yes there is. Either nobody is engineering towards that aspect or it is a conscious decision, deliberating between two different buckets: bill-of-material cost per unit and estimated impact on your warranty & goodwill budget. Whatever is deemed to be cheaper will win.

Source: I work at an automotive OEM and one of my first projects almost two decades ago was how to anchor after-sales requirements into the engineering process. For example, we did things like introducing special geometry into the CAD models representing the space that needs to be left free so a mechanic can fit his hands with a tool inside. These would then be considered in the packaging process. If you consider these are two completely different organizations, it becomes a very tricky problem to solve.

It's like the manufacturer discovering to their complete surprise they are building a car. :-D
