KIA SOUL vs MERCURY GRAND MARQUIS
Side-by-side comparison of the KIA SOUL and MERCURY GRAND MARQUIS drawn from the NHTSA consumer-complaint database, defect investigations, recall history, and NCAP crash-test ratings.
According to the National Highway Traffic Safety Administration (NHTSA), more than 2,054,142 consumer complaints have been filed against U.S. vehicles since 1995, as of June 2026. This is a head-to-head safety comparison between the KIA SOUL (2010–2025) and the MERCURY GRAND MARQUIS (1977–2011), drawn from that federal complaint and recall record; see our methodology for how the figures are compiled.
The KIA SOUL (2010–2025, 16 model years) carries 7,144 NHTSA consumer complaints and 34 safety recalls, while the MERCURY GRAND MARQUIS (1977–2011, 33 model years) carries 4,949 complaints and 39 recalls. Severity indicators for the pair split as follows: 400 vs 395 crashes, 456 vs 277 fires, and 29 vs 17 reported fatalities.
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 KIA SOUL, the leading complaint category is engine (2908 filings), followed by unknown or other and steering. For the MERCURY GRAND MARQUIS, it is exterior lighting (710), ahead of vehicle speed control and electrical system. 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.
NHTSA's New Car Assessment Program gives the KIA SOUL an average 4.4/5 crash-test rating versus 0/5 for the MERCURY GRAND MARQUIS, aggregated across all model years with published scores. 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.
