Newer diesel with least problems

Take the online reviews with a grain of salt, it doesn't matter what vehicle you are looking at somebody somewhere is going to be yowling. I still see people concerned about rumours of the Cummins overheating in pickups, that was resolved thirty years ago. The new crop are very reliable and will give years of service with prudent driving habits and reasonable maintenance. Sure, there are failures after all they are machines designed and built by humans (we are not infallible)but in the grand scheme of things the record is pretty good.
