MERCEDES-BENZ GLS 450 vs TOYOTA RAV4 PRIME

Side-by-side comparison of the MERCEDES-BENZ GLS 450 and TOYOTA RAV4 PRIME 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 2,000,000 consumer complaints have been filed against U.S. vehicles (2,054,142 as of August 2026). This is a head-to-head safety comparison between the MERCEDES-BENZ GLS 450 (2017–2024) and the TOYOTA RAV4 PRIME (2021–2024), drawn from that federal complaint and recall record; see our methodology for how the figures are compiled.

The MERCEDES-BENZ GLS 450 (2017–2024, 8 model years) carries 241 NHTSA consumer complaints and 31 safety recalls, while the TOYOTA RAV4 PRIME (2021–2024, 4 model years) carries 242 complaints and 7 recalls. Severity indicators for the pair split as follows: 23 vs 52 crashes, 23 vs 1 fires, and 0 vs 0 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 MERCEDES-BENZ GLS 450, the leading complaint category is electrical system (45 filings), followed by unknown or other and engine. For the TOYOTA RAV4 PRIME, it is electrical system (68), ahead of unknown or other and service brakes. 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.
