I'm thinking Vauxhall, Hyundai and Kia particularly here. Are these warranties giving owners additional protection at no extra cost or is the reality that the conditions, cost and scope of the relevant servicing regimes have been altered accordingly. So, for example, have major/important parts which are now more likely to fail under the extended warranty have been brought into the scope of the servicing regime so they are routinely replaced at the owner's expense before any failures are likely to occur and sooner than otherwise would have been the case?
