KENWORTH T660 vs VOLVO VNL (4)
Side-by-side comparison of the KENWORTH T660 and VOLVO VNL (4) 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 KENWORTH T660 (2008–2014) and the VOLVO VNL (4) (2023–2026), drawn from that federal complaint and recall record; see our methodology for how the figures are compiled.
The KENWORTH T660 (2008–2014, 5 model years) carries 10 NHTSA consumer complaints and 37 safety recalls, while the VOLVO VNL (4) (2023–2026, 3 model years) carries 10 complaints and 15 recalls. Severity indicators for the pair split as follows: 2 vs 4 crashes, 1 vs 3 fires, and 0 vs 1 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 KENWORTH T660, the leading complaint category is engine and engine cooling:engine:diesel (2 filings), followed by unknown or other and steering. For the VOLVO VNL (4), it is steering (3), ahead of electrical system and air bags. 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.
