Kei Truck Problems Database

These engines were built to run for decades, and most of what eventually goes wrong with an imported kei truck is age and neglect, not a design flaw. Almost every issue below is fixable, often cheap, and easy to check for before you buy or right after the truck lands. Each page is a structured breakdown of one specific, owner-reported problem — what it looks like, what causes it, what it costs to fix, and how to check for it yourself.
