Not trying to stir the pot here, but I doubt that any company that sells products of any kind (except food or drugs) will replace a product which is operating as intended. However, if the product fails for some reason and it is within the warranty period, then it is customary for the product to be replaced with another. I think Toyota will do the right thing and replace the engines that do fail for whatever reason. Toyota is not going to simply start replacing engines that have not failed unless their analysis has proven to them that they have a huge liability on their hands. Time will tell if Toyota, so far, has told the truth about how many units are affected. Until I learn otherwise, I will give Toyota the benefit of the doubt.
