I didn't realize that fast hardware iterations would have this consequence on repairs, but it makes sense to keep parts inventories very low -- and therefore surges of demand (and the Model 3 in 2H18 is nothing if not a surge in repair demand, simply due to total deliveries * expected repair rates) will run into delays in supply chain.
Glad the problem is getting incrementally better, at least!
