A True story: I was visiting a local junkyard several years ago and noticed a number of late model Nissan vans in the lot.
I asked how much they were and was told "Not for sale". It seems that a few of this model had engine fires and Nissan couldn't find an immediate reason why, so they paid people off and destroyed them. Car companies do this to avoid liability and warranties and hassles. It's just easier and simpler. You'll also notice that perfectly good useable buildings are invariably torn down to build new buildings ( Walmart comes to mind, in my locale). It's just simpler and quicker. Confront a major car company with a group of emotional electric car fanatics - who will bother and annoy them and claim warranties and demand service and demand parts supplies for years to come ... And what happens? They crush the vehicles.
