I think you’re getting it backwards. Because these are very large and important durable goods there is a robust post-sale monitoring infrastructure to fix problems if they arise afterwards. That’s a good sign, not a bad one. It is moreover a system which does not exist for all products. Separately, there is no quality control process in the world which would guarantee that this kind of product is totally free of any defect which might reduce safety.
