Raw complaint counts favor whichever nameplate has fewer vehicles on the road, so the cleaner lens is components: which specific part families concentrate each model's filings? For the MERCURY MARQUIS, the leading complaint category is vehicle speed control (31 filings), followed by power train:automatic transmission and electrical system. For the TOYOTA 4RUNNER, it is structure:body (1376), ahead of suspension and unknown or other. When the two vehicles cluster around the same component, the problem is likely a shared supplier or a shared federal standard under stress; when they diverge, each nameplate has its own defect signature independent of the other.

Average NCAP crash-test scores are not uniformly available for both nameplates in this dataset, which typically means one or both pre-date the 2011 rating methodology refresh. Use the side-by-side table below as your scorecard, but do not treat it as a verdict. Recall counts tell you how many defects the manufacturer has already been compelled to remedy; complaint counts tell you what owners are still flagging today; and safety ratings tell you how the vehicle performs in standardized barrier tests — three different lenses on the same underlying question. The "also compare" links at the bottom of this page let you triangulate against neighboring nameplates in each model's competitive set.
