A preliminary evaluation is NHTSA's first step, to gather information and decide whether to look further. An engineering analysis is a deeper review, usually opened after a preliminary evaluation. A recall query is a review of whether a recall covered the right vehicles or whether its fix works. NHTSA lists investigations by make, model and model year only, so one can apply to only some versions of a model, such as one engine; its summary says which.
