I generally agree, although it seems like Tesla service might be the problem, not the design. The article states that the depot the car was sent to only had the option to replace the battery. In other words, they don't have the tools and/or parts to remove the broken part and replace it. The repair could be done by Tesla if they wanted to, which means it's not necessarily bad design, but certainly bad service at a minimum.
